Meilleur hébergement Web écologique au Royaume-Uni (2026) – Haut 9 Comparaison des hôtes verts

Four of the six hosts on the last version of this list publish no evidence in the Green Web Foundation's directory. That nonprofit checks a host's renewable-energy paperwork before listing it. HostPapa quietly dropped green energy from its UK homepage in late 2024. And 123-reg's only environmental claim is "low-energy systems". So we rebuilt the list around proof: who publishes a certificate, where your server sits, and what the plan costs after year one.


Réponse rapide: Krystal is the best eco host for most UK sites. It costs a flat USD 9.34/mo (GBP 7) and runs from Netwise's East London data centre on power matched 100% with renewables. Vous obtenez également 60 jours pour changer d'avis. Kualo matches that evidence and hosts registered UK charities for free. Mythic Beasts is the cheapest verified-green UK option at a flat USD 3.34/mo (GBP 2.50).

Dernière révision: septembre 2026. Prix ​​et fonctionnalités vérifiés.


What changed since the last update? Eco Web Hosting cut its refund window and raised its prices in 2026. HostPapa no longer makes any green claim on its UK site. GreenGeeks' Lite plan is capped at 25 GB, not the unlimited space our old table showed. We kept all six original hosts, labelled the weak ones honestly, and added three UK hosts with published evidence: Krystal, 20i and Mythic Beasts.


Comment nous avons sélectionné ces fournisseurs

Every host here had to face one question first: can anyone outside the company confirm the green claim? Sur 19 septembre 2026 we ran all nine through the Green Web Foundation directory and its public checker. Where we could find a server that hosts customer sites, we tested its IP address, not the marketing site.


New additions had to clear three bars. They needed a directory entry with published evidence, a UK data centre for shared hosting, and an entry plan under USD 15/mo (GBP 11.24). We kept the six original hosts because none has shut down, even where the green case is thin.

What the Green Web Check Found

Here's the trap we hit first. A green result for a host's own website can be meaningless. greengeeks.com, hostpapa.co.uk and kualo.co.uk all pass because Cloudflare, which is registered as green, serves those pages. That describes the marketing site's front door, not the machine your website will run on.

So we looked at what each directory entry actually publishes, and tested server IPs where we could:

  • GreenGeeks: listed with a 2025 Bonneville Environmental Foundation report and a US EPA confirmation of its 300% correspondre. All four data-centre test IPs pass under GreenGeeks' own name.
  • Hébergement Web écologique: son parent, Enix Ltd, has an entry but publishes no supporting documents. The IPs behind its website, control panel and status page don't pass.
  • Kualo: listed with a certificate covering Netwise, its data-centre operator, de 1 avril 2026 à 31 Mars 2027. It shows Netwise buying REGOs (Renewable Energy Guarantees of Origin) for its whole supply. These are proof of renewable generation, registered with Ofgem, the UK energy regulator. A carbon-credit certificate sits alongside it.
  • 123-reg: no entry, and its domain doesn't pass.
  • HostPapa: no entry in the UK, Canadian or US directory. Its domains pass only through Cloudflare.
  • La pensée combinatoire de HowToHosting.guide a conduit à l'inclusion d'une représentation graphique moderne des données sur SiteCountry et à notre analyse approfondie des sources: no entry, and its domain doesn't pass.
  • Krystal: répertorié, and its sites resolve to Krystal's own registered network. Its entry publishes no documents, but its London servers sit in the building Netwise's certificate covers.
  • 20je: répertorié, but the only published evidence is 20i's own green-hosting page.
  • Bêtes mythiques: verified since March 2024, with reports from Telehouse, Digital Realty and Equinix, its data-centre operators.

We weighted proof of green power at 35%, a UK server at 25%, three-year cost at 25%, and refund and uptime terms at 15%. Sources were official pricing, terms and data-centre pages, plus the documents each directory entry publishes. We also used Netwise's efficiency figures, the Uptime Institute's 2025 survey, and Internet Archive copies to date policy changes.

Les limites sont réelles. We didn't run speed or load tests, and we read certificates rather than audit them. SiteCountry doesn't publish renewal prices, 20i doesn't say whether its prices include VAT, and Mythic Beasts publishes no refund period. Plus "renouvelable" claims here mean annual matching, not hour-by-hour supply. Prices exclude VAT unless noted and use the ECB rate of 18 septembre 2026 (GBP 1 = USD 1.3344).

GreenGeeks - Best for Certified Renewable Matching Outside the UK

À partir de 2,95 USD/mois (GBP 2.21), renouvelle en USD 13.95 | 25 GB SSD | Nearest server: Amsterdam | 30-jour de remboursement

GreenGeeks has the strongest paperwork of the international hosts here, and no server in Britain. Its four data centres sit in Chicago, Montréal, Amsterdam et Singapour. A UK visitor's request crosses the North Sea at minimum. Pour un blog, that hop barely registers; for a UK shop with a busy checkout, choose Amsterdam on purpose, pas par accident.

The green case holds up. GreenGeeks pays the Bonneville Environmental Foundation (BEF) to buy RECs (renewable energy certificates) equal to three times its estimated power use. It also plants one tree per new account and cites EPA Green Power Partner status since 2009. Its directory entry carries a 2025 rapport, and its customer IPs pass the check under its own name.

Year two is the problem. Lite costs USD 2.95/mo for the first 12 mois, then USD 13.95/mo, une 4.7x saut de renouvellement. Three years on Lite total USD 370.20 (GBP 277.42). C'est à peu près 3.1 times the USD 120.10 (GBP 90) Mythic Beasts charges for Web 25 sur la même période. Pour être juste, vous obtenez 25 GB contre 5 GB. You also get LiteSpeed caching, from a fast web server with built-in page caching. Un CDN gratuit (réseau de diffusion de contenu) serves files from locations near each visitor.

Avantages

  • 300% renewable matching, soutenu par un 2025 BEF report
  • Customer IPs pass the Green Web Check under its own name
  • LiteSpeed caching and a free CDN on every plan
  • One tree planted per new account

Les inconvénients

  • Pas de centre de données au Royaume-Uni; Amsterdam est la plus proche
  • Lite renews at USD 13.95/mo
  • Seulement 25 GB sur le plan d'entrée

Tarification: Lite 2,95 USD/mois (GBP 2.21) pour 12 mois, puis USD 13.95 (GBP 10.45); 1 site, 25 GB SSD. Pro USD 4.95 en USD 18.95 (GBP 3.71 à 14.20); sites illimités, 50 GB. Prime USD 8.95 en USD 30.95 (GBP 6.71 à 23.19); 100 GB. Facturé en USD. 30-jour de remboursement.

Meilleur pour: a site whose visitors are spread across Ireland, the Netherlands and the rest of Western Europe, not just Britain. Ignorer si: most visitors are British, or you plan to stay on Lite past year one.

Choose GreenGeeks only if certified renewable matching matters more than a UK server. For documented green power on a London server, Krystal costs a flat USD 9.34 and still undercuts Lite's three-year total. If price rules, Mythic Beasts costs about a third as much over three years.

Hébergement Web écologique - Best for Monthly Billing on UK Servers

From USD 5.99/mo (GBP 4.49), idem au renouvellement | 10 GB | Centres de données britanniques | 30-jour de remboursement

Start with two changes this year. Eco Web Hosting cut its money-back guarantee from 45 à 30 days in May 2026. Archived copies of its homepage place the switch between 10 et 13 Mai. Eco Web Hosting also raised Essential from USD 4.66 en USD 5.99 un mois (GBP 3.49 à 4.49) entre 9 juin et 25 juillet 2026. C'est un 29% hausse des prix, and older reviews still quote the old terms.

The trees are real; the evidence for the power is thinner. Each plan funds monthly tree planting in Nepal, Indonesia and Haiti, from one tree on Essential to four on Ultimate. The company says its data centres run on "100% sustainable energy" but names no facility. Its parent is Enix Ltd, which also runs HostPresto, Brixly and a separate brand called Eco Hosting. Enix has a Green Web Foundation entry, but it publishes no supporting documents.

What you do get is a UK server on a rolling monthly contract with no teaser price. Essential's USD 5.99 achète 10 GB, 25 boîtes aux lettres, a web application firewall and SSH access (command-line control of your files). Mythic Beasts' Web 35 gives the same 10 Go pour USD 4.67 (GBP 3.50). C'est des dollars américains 1.32 moins, with named data-centre evidence behind it.

Avantages

  • Centres de données britanniques, no promo-then-spike pricing
  • SSH, 25 mailboxes and a firewall on the entry plan
  • Monthly tree planting tied to your plan
  • Migration gratuite, généralement à l'intérieur 24 heures

Les inconvénients

  • Refund window cut to 30 journées en mai 2026
  • Essential up 29% depuis juin 2026
  • No published evidence behind the energy claim

Tarification: Essential USD 5.99/mo (GBP 4.49), ou USD 60.04 (GBP 44.99) a year with two months free; 1 site, 10 GB, 50 Bande passante GB. Professionnel USD 9.33 (GBP 6.99); 10 des sites, 50 GB per site. USD ultime 17.33 (GBP 12.99); sites illimités. The monthly rate is the ongoing rate. 30-jour de remboursement.

Meilleur pour: a small UK site owner who wants monthly billing, UK servers and tree planting they can point to. Ignorer si: you need documented renewable power; Kualo and Krystal both publish it for a few pounds more.

Pick Eco Web Hosting if a monthly, no-commitment UK plan with SSH is the whole brief. Si le mot "éco" has to survive scrutiny, Kualo's Solo costs USD 3.34 more and comes with a Netwise energy certificate. If price is the brief, Mythic Beasts is cheaper and better documented.

Kualo - Best for UK Charities and Small Businesses

From USD 9.33/mo (GBP 6.99), idem au renouvellement | 10 GB SSD | East London data centre | 60-jour de remboursement

If you run a registered UK charity, Kualo will probably host your site for nothing. Its Solo plan is free or half price for eligible charities, and Kualo says it has supported more than 1,000 jusqu'à présent. The conditions are light: move your domain to Kualo and add a small footer link.

The evidence is the best documented on this list. Kualo's directory entry links an energy broker's certificate for Netwise, valid until 31 Mars 2027. It states that REGOs covering 100% of Netwise's supply were retired into Netwise's own account on the Ofgem register. Kualo says it buys the power from Statkraft, whose sites include the Baillie wind farm in the Scottish Highlands.

Efficiency is the other half. Netwise lists its London East facility at a PUE of 1.10 (power usage effectiveness: total power drawn divided by power reaching the servers). le Uptime Institute's 2025 survey puts the global average at 1.54. So overhead drops from 54p to 10p per pound of server power. One loose end: Kualo's green page still describes a rooftop solar array due "par 2025" as planned.

Sur le prix, Solo costs USD 9.33 (GBP 6.99) against Krystal's USD 9.34 (GBP 7) pour le même 10 GB. Prepay three years and Kualo drops to USD 6.74 (GBP 5.05) un mois.

Avantages

  • REGO-backed renewable power, certificate valid to March 2027
  • Free or half-price hosting for registered UK charities
  • 99.9% garantie de disponibilité avec crédits de service
  • 24/7 phone support and 30 sauvegardes quotidiennes conservées

Les inconvénients

  • Seulement 10 GB SSD on Solo
  • Solo hosts one site; unlimited sites start at USD 14.67
  • Solar array promised for 2025 is still "planned"

Tarification: Solo USD 9.33/mo (GBP 6.99); 1 site, 10 GB SSD; ou USD 242.52 (GBP 181.74) for three years upfront. Startup USD 14.67 (GBP 10.99); sites illimités, 30 GB. Performances USD 24.01 (GBP 17.99); 50 GB, Redis et Memcached. No introductory discount. 60-jour de remboursement.

Meilleur pour: registered UK charities, and small businesses that want a certificate they can show a client. Ignorer si: 10 GB is too tight and energy isn't your filter; HostPapa gives 25 Go pour USD 2.60.

Kualo is the pick when the green claim has to hold up in a supplier review or grant report, and for any registered charity. Need more than 10 Go pour environ USD 9? Mythic Beasts' Web 70 donne 25 GB. Against Krystal, you're choosing between two hosts in one Netwise building, so decide on site limits and support.

123-reg - Best for Keeping Domains and Hosting in One UK Account

À partir de 2,66 USD/mois (GBP 1.99) pour 3 années, renouvelle en USD 9.33 (GBP 6.99) | 25 GB NVMe | 14-jour de remboursement

USD 2.66 un mois (GBP 1.99) buys three years of 123-reg's Economy plan. The next three years cost USD 9.33 un mois (GBP 6.99), a 3.5x step. That renewal matches Kualo's Solo to the penny, and Kualo's price comes with a renewable-energy certificate.

123-reg's entire environmental statement is one line on its About page: son "eco-friendly data centres are powered by low-energy systems." There's no renewable-energy claim, no certificate and no Green Web Foundation entry. (Credit where it's due: that's more modest than a green badge with nothing behind it.) It stays on this page because it was on the previous version, and removing it quietly would hide that finding.

The hosting itself is ordinary in a useful way. Economy gives one site 25 Go de NVMe (stockage flash rapide), sauvegardes quotidiennes, cPanel and DDoS protection against floods of junk traffic. 123-reg has sold UK domains since 2000 and has been part of GoDaddy since 2017. Refunds are tight: 14 journées, and you have to phone to ask.

Avantages

  • 25 GB NVMe sur le plan d'entrée
  • Sauvegardes quotidiennes et protection DDoS incluses
  • Domains and hosting on one UK bill

Les inconvénients

  • No renewable claim, certificate or directory entry
  • Economy renews at 3.5X le prix d'entrée
  • 14-jour de remboursement, the shortest on this page

Tarification: Economy USD 2.66/mo (GBP 1.99) pour une durée de trois ans, USD 95.60 (GBP 71.64) dès le départ, renouvellement en USD 335.79 (GBP 251.64) tous les trois ans. Deluxe USD 3.99 en USD 12.00 (GBP 2.99 à 8.99). USD ultime 6.66 en USD 16.00 (GBP 4.99 à 11.99). Maximum USD 7.99 en USD 21.34 (GBP 5.99 à 15.99).

Meilleur pour: someone whose domains already live at 123-reg and who wants a single bill. Ignorer si: green credentials are the reason you're reading this page.

Don't buy 123-reg as an eco host; it doesn't claim to be one. If your domains are there, keep them and point them at Kualo or Krystal. Both cost the same USD 9.33 à 9.34 au renouvellement, with evidence attached. If you want the lowest bill, Mythic Beasts renews at USD 3.34.

HostPapa - Best for Cheap NVMe Storage (Not a Green Pick)

From USD 2.60/mo (GBP 1.95) pour 3 années, renouvelle en USD 6.66 (GBP 4.99) | 25 GB NVMe | Nearest server: Amsterdam | 30-jour de remboursement

Where GreenGeeks still publishes a 2025 renewable-energy report, HostPapa's UK site no longer mentions energy at all. HostPapa removed the green-energy section from its UK homepage between 25 septembre et 4 décembre 2024. Today its plan, About and data-centre pages say nothing about renewables either.

Older reviews, including the previous version of this page, still describe HostPapa buying RECs. We couldn't find that claim on any current HostPapa page. HostPapa has no Green Web Foundation entry in the UK, Canada or the US, and its domains pass the check only through Cloudflare. Notre Comparaison HostPapa et GreenGeeks covers the two on speed and pricing.

As plain hosting, the numbers are decent. Essentials gives 25 GB of NVMe for USD 2.60 (GBP 1.95) et renouvelle en USD 6.66 pour une durée de trois ans. C'est un 2.6x step, against GreenGeeks' 4.7x. The data centres are Toronto, Les anges, Buffle, Miami et Amsterdam, so UK traffic goes to Amsterdam. HostPapa bought the US host Hostwinds on 29 avril 2026, ajout de Seattle, Dallas and Amsterdam facilities, none of them in the UK.

Avantages

  • 25 GB NVMe for USD 2.60/mo
  • Renewal prices published for every billing term
  • Isolement CloudLinux, CDN and staging on Essentials

Les inconvénients

  • No current green claim and no directory entry
  • Pas de centre de données au Royaume-Uni; Amsterdam est la plus proche
  • Monthly renewal reaches USD 13.33 (GBP 9.99)

Tarification: Essentials USD 2.60/mo (GBP 1.95) sur 36 mois. Il se renouvelle en USD 6.66 (GBP 4.99) sur 36 mois, USD 10.66 (GBP 7.99) sur 12, ou USD 13.33 (GBP 9.99) mensuel. Croissance USD 3.27 (GBP 2.45); 5 des sites, 100 GB. Prime USD 3.94 (GBP 2.95); 200 GB. Élite USD 6.61 (GBP 4.95). 30-jour de remboursement.

Meilleur pour: a budget site that needs room to grow and isn't choosing a host for its energy source. Ignorer si: you came here for green hosting; Mythic Beasts costs USD 0.74 more a month and has published evidence.

HostPapa is a budget storage pick, not an eco pick, and we've labelled it that way. Buy it for 25 Go en USD 2.60 if energy isn't your filter. Si c'est le cas, Mythic Beasts carries directory-verified evidence for a little more, and Krystal puts you on a London server.

La pensée combinatoire de HowToHosting.guide a conduit à l'inclusion d'une représentation graphique moderne des données sur SiteCountry et à notre analyse approfondie des sources - Best for Very Cheap Side Projects Hosted Outside the UK

From USD 1.31/mo (GBP 0.98) pour 4 années, renouvellement inédit | 100 GB NVMe | Pas de serveur au Royaume-Uni | 30-jour de remboursement

Besoin 100 GB for a hobby project and don't care where the server sits? SiteCountry's price is hard to argue with. Premium Cloud Lite costs USD 1.31 a month on a four-year term, ou USD 62.64 (GBP 46.94) dès le départ. That's less than 19 months of Mythic Beasts' Web 25, pour 20 times the storage.

The green side is a label and nothing more. SiteCountry's data-centre page says "green-friendly hosting" without naming an energy source, certificate or partner. It has no Green Web Foundation entry. Its servers are in Dallas or North Carolina, Germany or Poland, et Inde, and none of them is in the UK.

Read the terms before paying for four years. The renewal price isn't published; the only reference is the struck-through USD 4.35 prix catalogue, 3.3 times the four-year rate. Refunds cover the first purchase within 30 journées, jamais de renouvellement. (Four years is a long time to trust a sale price.) The terms also let SiteCountry delete an expired account's data from 24 hours after expiry. A missed renewal can cost you the site.

Avantages

  • 100 GB NVMe et 100 sites for USD 1.31/mo
  • LiteSpeed and CloudLinux on the entry plan
  • 30-day refund on the first purchase

Les inconvénients

  • No UK data centre and no green evidence
  • Prix ​​de renouvellement non publié
  • Expired data can go after 24 heures

Tarification: Premium Cloud Lite USD 1.31/mo on 4 années (USD 62.64 dès le départ) or USD 2.17/mo on 1 an (USD 26.06); list price USD 4.35. 100 des sites, 100 GB NVMe, 2 Go de RAM, 90 Bande passante GB. Pro starts at USD 2.19 et Turbo en USD 2.82 on the same four-year term. These are summer-sale prices, vérifié 19 septembre 2026.

Meilleur pour: a test site or side project where storage per dollar is the only metric. Ignorer si: the site earns money, serves UK visitors, or needs to count as green.

SiteCountry doesn't belong on a green shortlist on current evidence. For a throwaway project, it's the cheapest storage on the page. For anything that matters, Mythic Beasts costs about USD 2 plus d'un mois, sits in the UK and has evidence.

Krystal - Best Overall Eco Host for UK Sites

From USD 9.34/mo (GBP 7), idem au renouvellement | 10 GB NVMe | Netwise East, Londres | 99.99% garantie de disponibilité | 60-jour de remboursement

Krystal is the benchmark the rest of this list gets measured against. It rents space in Netwise's East London data centre, where power is matched 100% with renewables. It has been a certified B Corp since 2023, meaning B Lab audits its environmental and governance practices. It also plants a tree every month for each active client.

What sets Krystal apart is how carefully it words the claim. Its green page says "matched", ne pas "powered", and explains that grid electricity can't be traced to one wind farm. It also quotes a PUE of 1.17 pour 2024/25, reported under the UK's Climate Change Agreement scheme, which ties energy-tax discounts to efficiency targets. That's less flattering than the 1.10 on Netwise's own page, and more believable for it. The Netwise certificate that backs Kualo's listing covers this building's supply too.

Le prix est forfaitaire. Amethyst costs USD 9.34 (GBP 7) now and at renewal, so three years on monthly billing total USD 336.27 (GBP 252). GreenGeeks' Lite, which starts at a third of the price, coûte USD 370.20 au cours des mêmes trois années. Amethyst covers one site and 10 GB, avec un 99.99% garantie de disponibilité and a 60-day refund.

Avantages

  • London servers on renewable-matched power
  • Certified B Corp with a published 2026-2029 climate plan
  • Flat pricing and a 60-jour de remboursement
  • LiteSpeed and NVMe on every plan

Les inconvénients

  • One site and 10 GB sur Améthyste
  • Free domain only from the Ruby tier
  • Nearly three times Mythic Beasts' entry price

Tarification: Amethyst USD 9.34/mo (GBP 7); 1 site, 10 GB NVMe, 2 Go de RAM. Rubis USD 14.68 (GBP 11); 5 des sites, 25 GB, domaine gratuit. Émeraude USD 25.35 (GBP 19); unlimited sites and NVMe storage. Économies de facturation annuelle 16% and biennial 25%. Même prix au renouvellement.

Meilleur pour: a UK business, freelancer or blogger who wants London servers, published evidence and the same price at renewal. Ignorer si: your budget is under USD 5; Mythic Beasts delivers verified green UK hosting for USD 3.34.

Krystal is our default recommendation for a UK site that must be green on paper and quick for British visitors. Charities should compare Kualo first, since a free Solo plan beats any price. Developers on a tight budget will get more from Mythic Beasts.

USD 1.33 (GBP 1) premier mois, then USD 13.34/mo (GBP 10) | 10 GB | Centre de données britannique | 30-jour de remboursement

20i's published green evidence points back at 20i. Its Green Web Foundation entry links to 20i's own green-hosting page, not to a certificate or a data-centre operator's report. That page claims 100% renewable power through "renewable energy suppliers and cloud partners" and a PUE of 1.2 in its own data centres.

The numbers still compare well. A PUE of 1.2 beats the Uptime Institute's 1.54 global average, though it trails the 1.10 that Netwise reports for Krystal's and Kualo's building. 20i's head office at Ransom Wood in Nottinghamshire runs on 2,088 solar panels. Nice touch, but that powers the office, not your server.

The platform is why you'd pay more. 20i autoscales shared sites during traffic spikes, includes a free CDN, and keeps 30 days of site backups and 60 days of database backups. Startup costs USD 13.34 (GBP 10) après un USD 1.33 premier mois. C'est des dollars américains 4 more than Krystal's Amethyst for the same 10 GB, ou USD 132.11 more over three years.

Avantages

  • Mise à l'échelle automatique pour les pics de trafic, plus a free CDN
  • 30-day site and 60-day database backup retention
  • Royaume-Uni, US and Singapore data centres from one account

Les inconvénients

  • Only published green evidence is 20i's own page
  • USD 13.34 for one site and 10 GB
  • Prices can change on 14 days' notice

Tarification: Startup USD 1.33 (GBP 1) pour le premier mois, then USD 13.34/mo (GBP 10); 1 site, 10 GB, 50 Bande passante GB. Plan 1 USD 26.69 (GBP 20). Plan 2 USD 53.38 (GBP 40) pour 3 des sites. Pas de contrat. The plan page doesn't say whether prices include VAT. 30-jour de remboursement, one per customer.

Meilleur pour: a UK shop or campaign site that sees sudden traffic bursts and needs the host to absorb them. Ignorer si: you run a steady brochure site; Krystal is USD 4 a month cheaper with stronger evidence.

Choose 20i for autoscaling and long backup retention, not for the strongest green paperwork. If documentation matters most, Kualo's REGO-backed Solo costs USD 4.01 moins. If price matters most, Mythic Beasts costs a quarter as much.

Backups run daily, with a guarantee to restore files to no more than 36 hours before a failure. la toile 25 est 64% cheaper than Kualo's Solo but holds half the storage. la toile 35 closes that gap at USD 4.67 (GBP 3.50) pour 10 GB.

Eco-Web-Hosting-in-the-UK-howtohosting-guide

Charity with one small site: A registered UK charity with one site under 10 GB should take Kualo Solo, free or half price. Nothing else here beats zero. A community group without charity registration should look at Mythic Beasts’ la toile 35 en USD 4.67 (GBP 3.50), the cheapest verified plan with 10 GB.

Budget: en dessous du dollar 5 un mois. You want a UK server and published evidence for less than USD 5 (GBP 3.75). Pick Mythic Beasts Web 25 or Web 35. Skip SiteCountry even though USD 1.31 looks better: no UK server, no evidence and no published renewal. HostPapa’s USD 2.60 (USD 6.66 au renouvellement) fails the same first two tests.

Public: mostly British, 2-5 des sites. Si 80% or more of your visitors are in the UK and you need under 25 GB in total, Krystal Ruby fits. It covers five sites on a London server for USD 14.68 (GBP 11). Past five sites, Kualo Startup costs USD 14.67 (GBP 10.99) for unlimited sites and 30 GB. GreenGeeks Pro is cheaper in year one, but it serves you from Amsterdam and renews at USD 18.95.

Staying five years or longer? Favour flat pricing over a low first bill. Plus de 36 mois, Mythic Beasts totals USD 120.10 and Krystal USD 336.27. GreenGeeks Lite totals USD 370.20, despite starting at USD 2.95.

Questions fréquemment posées

Can I trust the Green Web Check result for my website?

Only if you test the right thing. Check your own site’s address once it’s live, not the host’s homepage. greengeeks.com, hostpapa.co.uk and kualo.co.uk all pass because Cloudflare serves them, which says nothing about the servers behind them. If your site also sits behind Cloudflare, ask your host for the server IP and test that.

Which green UK host is cheapest over three years?

Bêtes mythiques, en USD 120.10 (GBP 90) pour 36 months of Web 25, with no price rise. Kualo’s Solo costs USD 242.52 (GBP 181.74) if you prepay three years. GreenGeeks Lite looks cheapest at USD 2.95, but it totals USD 370.20 once the renewal starts.

Does GreenGeeks have a UK data centre?

Non. GreenGeeks runs data centres in Chicago, Montréal, Amsterdam et Singapour, and Amsterdam is the closest to Britain. For renewable-matched hosting on a London server, Krystal and Kualo both use Netwise’s East London facility.
