Fonctionnalités et services

The company has been hosting since January 2000 and calls itself a managed provider. That word does a lot of work here. Cheap shared plans exist, but the business is built around servers somebody else runs.

Types d'hébergement proposés

• Hébergement partagé, Linux et Windows – five tiers, 1GB to 15GB of disk
• Hébergement premium – plafonné à 30 sites per server, with dedicated vCPU and RAM
• VPS géré – five tiers, cPanel ou Plesk
• Serveurs dédiés – virtual and physical, quoted individually
• Revendeur, e-mail uniquement, Microsoft 365, and managed AWS or Azure

Principales caractéristiques mises en avant par les clients

Read the reviews and a pattern shows up fast. People aren’t praising the control panel or the speed. They’re praising a free UK number that reaches someone who fixes the problem.

• Gratuit 24/7 Assistance téléphonique au Royaume-Uni – the most mentioned feature in the reviews, par une large marge
• Named contacts – reviewers describe reaching the same engineer repeatedly
• Migrations gratuites – sur chaque plan, and quantified on VPS tiers (5 à 50 depending on size)
• Offsite backups included – daily R1Soft CDP backups kept 7 journées, plus weekly server snapshots
• ISO 27001 et ISO 9001 – the ISO 27001 certificate comes from a UKAS accredited body

Emplacements des centres de données

Everything sits in the UK. The primary site is Telehouse Europe in London Docklands, with a secondary network in Reading, both rated Tier 3+. Transit runs over 10G links to Telia and NTT, with extra capacity from Cogent and GTT. As a RIPE member, catalyst2 can assign IP addresses in your own company’s name.

Voici le compromis. UK-only means low latency for British visitors and a clean data residency story. It also does nothing for an audience in Sydney or Sao Paulo.

Attentes en matière de performances

No independent benchmark data for catalyst2 turned up during this research: no third-party speed tests, pas de surveillance externe de la disponibilité. That gap is worth naming.

What does exist is catalyst2’s own public status page. À partir de 3 août 2026 it shows 100.0% uptime over the trailing 90 journées, across all six monitored components. The incident log going back to 2022 listes 12 événements. 2024 was the rough year. Reading data centre network problems ran from 20 à 27 février, and Telehouse was unstable from 10 à 12 avril. It’s been quiet since.

Une mise en garde: catalyst2’s uptime marketing quotes three different numbers, unpicked in the transparency section below.

Expérience client

Sur Trustpilot, catalyst2 holds a 5.0 score de 532 Commentaires. The distribution is extreme: 523 cinq étoiles, 7 quatre étoiles, no three-star, one two-star and one one-star. C'est 98.3% cinq étoiles.

Before you weigh that, two things are worth knowing. The profile isn’t a paid one, so catalyst2 isn’t buying placement. But volume has collapsed. Twenty three reviews arrived in the last twelve months, contre 52 dans 2021 seul.

Ce que les clients louent

Soutien, soutien, soutien. Reviewers describe ringing a free number and getting a human quickly, often the same one as last time. Recent titles read “Catalyst2 support is really excellent” et “Excellent service since 2002”. This isn’t a company people compliment for its dashboard, and several reviewers describe relationships measured in decades.

Plaintes courantes

Here’s the honest difficulty. Only two of 532 reviews are negative. That isn’t proof of perfection, it’s a very thin sample.

That single 1-star review, from September 2019, is worth reading before you sign up. A long-standing customer praised the technical support, then turned on the accounts department. They said cancellation emails went ignored, and a card on file was charged twice in twelve months. That’s one account from seven years ago, and the company has changed hands since. But billing is where a corpus this positive tells you least. Check how cancellation works before you need it.

A clearer complaint is structural rather than reported. Storage is tight: 1GB sur le plan d'entrée, 15GB on the top tier. Email is tighter still, at 150MB per mailbox on Startup and 500MB even on the GBP 61.99/mo Group plan.

Commentaires de la communauté (Reddit et forums)

There isn’t any. We searched Reddit for the company name, le domaine, and both with hosting terms. The results are all about a Garmin dash camera and a video game. No hosting subreddit mentions catalyst2, and no forum discussion surfaced.

Autre part, two review platforms carry catalyst2 profiles with zero user reviews between them. One has an expert write-up from December 2024, still quoting a 500MB entry plan.

So what does the silence mean? A 12-person business host doesn’t generate forum arguments the way a mass-market brand does. But it means one thing. Apart from the review platform, there’s no unfiltered record to check the official one against.

And that source has changed character. À travers 2021 the reviews arrived unprompted: 51 organic against one invited. Dans 2026, tout 14 came from invitation links. The rating hasn’t moved, but who’s talking has.

Qualité de l'assistance

Channels are a free UK phone line on 0800 107 7979, email, and a ticket portal, all advertised as 24/7/365 and UK staffed.

The phone number is the point. Most hosts at this price bury voice support behind a top tier, or drop it. catalyst2 puts it at the top of every product page.

One data point on behaviour when things break. A network transit disruption on 4 Mars 2025 lasted eight minutes. Three days later catalyst2 published a postmortem, admitting the cause was maintenance wrongly classified as non-service-affecting. Plenty of hosts would have quietly closed that ticket.

When to Use catalyst2

There’s a specific buyer this host fits, and it isn’t the one most hosting reviews are written for.

Idéal pour

UK businesses that need to phone someone: If a broken site costs you money per hour, un libre 24/7 phone line beats extra disk. That’s the whole proposition, and the reviews say it works.

Agences gérant des sites clients: Migrations gratuites, plans revendeurs, a dedicated account manager, and an ISO 27001 certificate you can show clients. The 30-sites-per-server cap on Premium is a real commitment, pas de commercialisation.

Organisations with UK data residency requirements: Everything sits in Telehouse London and Reading, which answers the question cleanly for UK-only contracts.

Anyone tired of renewal games: No promo pricing means no cliff. If a host has ever tripled your price in year two, c'est rafraîchissant.

Vous l'apprécierez si

• You want backups you didn’t configure, because 7-day offsite retention is standard
• You need IP addresses in your own company’s name, because catalyst2 is a RIPE member
• Your compliance team asks for ISO 27001 and Cyber Essentials certificates

When NOT to Use catalyst2

Aucun hôte ne convient à tout le monde. catalyst2 is the wrong choice in several cases.

Regardez ailleurs si

Vous êtes sensible au prix: GBP 22.99 a year buys 1GB of disk and one mailbox. Budget hosts give many times that. Pour un projet de loisir, you’re paying for support you’ll never call.

You need a modern stack documented: Every shared plan card lists “MySQL 5”. MySQL 5.7 reached end of life on 31 octobre 2023. The WordPress page advertises “PHP 7”, et PHP 7.4 was retired on 28 novembre 2022. The Windows order page still specifies “les fenêtres 2012 R2 with IIS7”, which Microsoft stopped supporting on 10 octobre 2023. These may be stale pages rather than stale servers, so ask before you buy. A managed host shouldn’t advertise retired versions in 2026.

Cheap compute matters more than management: A managed VPS starts at GBP 74.99/mo for 1 vCPU et 1 Go de RAM. If you can administer Linux, unmanaged providers offer far more for a fraction.

Your audience isn’t in the UK: No data centres outside Britain, and no CDN. Visitors from other continents will feel it.

Mailbox size matters: catalyst2’s dearest email plan gives 500MB per mailbox. Microsoft 365 Business Basic costs GBP 5.40 per user per month ex VAT and includes 100GB. You’d pay more per head for roughly 200 times the space.

Drapeaux rouges pour votre situation

• You want an uptime guarantee in writing: The homepage says “100% Disponibilité du réseau”, but the terms contain no percentage. Clause 1.3.2 États: “We shall not be liable for hosting hardware downtime or interruptions to the Service.”
• You want prices before talking to sales: Every dedicated configuration says “call for pricing”, and the cheapest VPS tiers can’t be ordered online.
• You want a clean refund: The 30-day guarantee deducts a GBP 10.00 admin fee, excludes add-ons, and clause 4.1 makes it subject to catalyst2’s acceptance.
• You register a lot of domains: A .co.uk is GBP 20.88 with no introductory rate, roughly double the market price every year.

Si l'un de ces éléments s'applique, voir les alternatives ci-dessous.

catalyst2 Plans and Pricing

All prices are in pounds and exclude VAT. Ajouter 20% if you can’t reclaim it.

Renewal check: catalyst2 does something unusual, and it deserves credit. There are no promotional first-term prices, so there’s no renewal cliff. Le GBP 5.49 you pay in month one is the GBP 5.49 vous payez la troisième année. Deux prises. The opening price is already what many hosts charge on renewal, and clause 3.1.5 lets catalyst2 raise it at any renewal.

Hébergement partagé

Méga offre: GBP 22.99/yr. 1Disque Go, 5Transfert de Go, 1 boîte aux lettres, 1 domaine. Facturation annuelle uniquement.

Méga Plus: GBP 5.49/mo or GBP 59.99/yr. 2Disque Go, 20Transfert de Go, 10 boîtes aux lettres.

Puissance: GBP 8.99/mo or GBP 95.99/yr. 3Disque Go, 40Transfert de Go, 50 boîtes aux lettres, 2 domaines.

Power Plus: GBP 13.99/mo or GBP 149.99/yr. 5Disque Go, 80Transfert de Go, 100 boîtes aux lettres, 5 domaines.

PowerXtra: GBP 19.99/mo on the website, GBP 21.99/mo in the order cart. 15Disque Go, 160Transfert de Go, 150 boîtes aux lettres, 10 domaines.

That last line isn’t a typo. The web hosting page prices PowerXtra at GBP 19.99 un mois, and the store charges GBP 21.99. C'est 24 pounds a year, on the tier a business is most likely to buy. Check the cart total before you confirm.

Paying annually saves 8 à 11 pour cent. Mega Plus is GBP 59.99 a year against GBP 65.88 payé mensuellement.

Hébergement Premium

Linux: Bronze GBP 49.99/mo (10GB), Silver GBP 79.99/mo (20GB), Gold GBP 111.99/mo (50GB). Windows matches at Bronze, then costs less: GBP 73.99 et GBP 101.99.

Premium buys a server holding no more than 30 des sites, plus dedicated vCPU and RAM, SSH access and separate mail servers. Il exécute LiteSpeed, a web server that handles busy sites more efficiently than Apache.

VPS géré

Squirrel GBP 74.99/mo (1 vCPU, 1Go de RAM, 20GB). Kangaroo GBP 137.99/mo (2 vCPU, 2GB, 40GB). Girafe GBP 196.99/mo (3 vCPU, 3GB, 60GB). Zebra GBP 316.99/mo (4 vCPU, 6GB, 100GB). Guépard GBP 417.99/mo (6 vCPU, 10GB, 200GB).

These are fully managed prices, and they’re high. GBP 74.99 a month for one vCPU isn’t competing with unmanaged providers, and isn’t trying to. You’re paying someone to patch it and answer the phone at 2am. One oddity: only Giraffe, Zebra and Cheetah are orderable online.

Serveurs dédiés

From GBP 99/mo, but every published configuration says “call for pricing”. You can see the specs, de 4 à 8 vCPU virtual or Xeon 4-core to dual 8-core physical. You can’t see a number without a quote form.

Coûts cachés à surveiller

• Domaines: GBP 20.88/yr for .co.uk and .uk, GBP 27.84/yr for .com. There’s no first-year discount, so registration and renewal cost the same. IONOS UK renews a .co.uk at GBP 10.00 hors TVA, making catalyst2 2.09 times the price every year.
• SSL: Let’s Encrypt is free and included. Paid certificates run GBP 99/yr, or GBP 499/yr for extended validation.
• Sauvegardes et migration: both included, but retention beyond 7 days is a quote, not a listed price.
• Remboursements: GBP 10.00 is deducted from any refund, and add-ons aren’t refundable at all.

Verdict sur les prix

catalyst2 is expensive and honest about it, which beats cheap and misleading. Nobody gets a nasty surprise at renewal. But the entry plan is 1GB and one mailbox for GBP 22.99 une année. Domains are the weakest line: double the going rate, jamais réduit.

catalyst2 Transparency Score

This rates how openly catalyst2 publishes information, separate from service quality.

• Informations sur la société: Limité. Founding date, staff size, certifications and both data centre locations are published, which beats most hosts. But the About page never mentions that catalyst2 is part of team.blue. Only the privacy policy does, and that policy names company number NI049920 as data controller. Companies House records NI049920, Catalyst 2 Services Ltd, as dissolved on 23 décembre 2025.
• Transparence des prix: Mixte. Strong where it matters most, because no promo rate hides a renewal jump. Weak on consistency. The web hosting page’s title tag reads “Prices now start at GBP 20.99”. Its body copy says “from just GBP 1 par mois”. The cheapest plan is actually GBP 22.99 une année.
• Documentation technique: Mixte. The infrastructure page is unusually good, naming the data centres, transit providers and backup software. Then the product pages undercut it by advertising MySQL 5, PHP 7 et Windows 2012 R2.
• Conditions et politiques: Good on money, poor on uptime. The refund clause is specific down to the GBP 10.00 admin fee. But no service level agreement appears anywhere in the terms, while the marketing advertises three different availability figures.

Overall transparency: middling, and the gaps cluster in one place. catalyst2 is candid about cost, refunds and infrastructure. It falls down on anything that needed updating: la possession, software versions, uptime claims, and an awards page whose newest entry is from 2021.

Alternatives to catalyst2

These three cover catalyst2’s gaps.

For Lower Cost: mainstream shared hosting

Want more than 1GB of disk, and no phone line? The big shared hosts undercut catalyst2 heavily, but watch for the renewal jump it avoids. Notre comparaison d'hébergement mutualisé shows promo and renewal prices side by side.

For Cheaper Compute: unmanaged and semi-managed VPS

GBP 74.99 un mois pour 1 vCPU is a management fee, not a server price. Notre Guide d'hébergement VPS covers providers that still manage the server for less.

For a Written SLA and Bigger Mailboxes: another UK managed host

Other UK hosts offer UK support and data centres, and some commit to uptime in the contract. Notre managed hosting comparison puts catalyst2’s price in context. If it’s the 500MB mailbox cap that’s blocking you, notre guide d'hébergement de messagerie covers hosts giving tens of gigabytes per user.

Conclusion

Copiez ce résultat

catalyst2 earns its 5.0 hors de 5. The reviews are real, the phone gets answered, and the pricing is honest in a market where that’s rare.

L'essentiel

Avec 5.0 à travers 532 Commentaires, catalyst2 delivers support customers describe in terms most hosts never earn. It falls short on value, on published specifications, and on backing its uptime marketing with a contract. Buy it if you’re a UK business that will use the phone number. Skip it if you want disk space per pound.

Two things to hold in mind. catalyst2’s original operating company, Catalyst 2 Services Ltd, was dissolved on 23 décembre 2025. catalyst2 now trades under Team Blue Internet Services UK Limited, part of team.blue. Any review describing it as an independent Belfast business is out of date. Deuxième, the review flow has thinned to 23 une année, all now invitation-sourced.

Questions fréquemment posées

Is catalyst2 good for beginners?

Oui, if you can afford it. Le libre 24/7 UK phone line means you’re never stuck alone with a problem. But the entry plan gives 1GB of disk and one mailbox for GBP 22.99 une année. Beginners can get more elsewhere. Support is the reason to choose it.

Is catalyst2 worth the price?

Depends what you’re buying. As disk space and bandwidth, non. As a managed service with a phone number, souvent oui. There’s no renewal shock, which is real money over three years. The weakest value is domains, en GBP 20.88 a year for a .co.uk, roughly double the going rate.

De quoi les clients se plaignent-ils le plus ??

Almost nothing, which is itself worth knowing. Only two of 532 reviews are negative. The one 1-star review, from September 2019, described the accounts team ignoring cancellation emails and charging a stored card. The weakness nobody complains about is storage.

Does catalyst2 guarantee uptime?

Not in the contract. The website advertises 100% disponibilité du réseau, the VPS plans mention a 99.9% SALADE, and the infrastructure page cites 99.97%. The terms state no percentage, saying catalyst2 “shall not be liable for hosting hardware downtime”. Its status page showed 100.0% pour le 90 jours pour 3 août 2026.

Is catalyst2 good for WordPress?

It sells managed WordPress plans from GBP 44.99 un mois pour 25,000 visites, a premium price for a modest allowance. The bigger concern is that the page still advertises PHP 7, retired in November 2022. Ask which version you’ll get before ordering.

Does catalyst2 offer refunds?

Oui, 30 journées, avec conditions. Un GBP 10.00 administration fee comes off the refund, add-ons aren’t covered, and domain registry charges are excluded. The terms also make the refund subject to catalyst2 accepting it. Cancelling deletes your site, so back it up first.
