How Much Does Website Maintenance Cost in the UK (and What Should It Include)?

Ask what website maintenance costs and most of the answers you find are quietly selling you something. The figure stretches to fit the care plan of whoever wrote the page, the "average" arrives without a source, and somehow nobody ever mentions that some websites need very little maintenance at all.

So here is the honest version: realistic 2026 UK prices with the sources named, what you should expect for the money at each level, and a straight answer on when doing it yourself is perfectly sensible.

What does website maintenance mean, and what does it not cover?

Maintenance is the work of keeping the website you already have running safely: software and plugin updates, backups that are tested, security patching, uptime monitoring, and renewals for your domain and hosting. It is the website equivalent of servicing a car.

What it is not is improvement. Redesigning pages, adding features, writing content and working on your search visibility are growth work, a different product usually sold as a retainer at a different price. The distinction matters because a common trick in this market is blurring the two, so a business that needs £50 of upkeep is sold a £500 plan on the promise of vague "improvements". Keep the two questions separate: what keeps the site running, and what makes it earn more. This guide prices the first.

How much does website maintenance cost in the UK?

Built from published UK prices rather than a finger in the air. UK IT Services' 2026 pricing guide tiers the market at £30 to £75 a month for basic cover and £75 to £200 for a standard business plan, with premium and ecommerce cover above that. FMEOS, a UK provider that publishes its prices, charges £45 a month for its basic package with two support hours, £129 for six hours, and £520 for its premium plan with thirty. Those two independent sources agree closely enough to draw an honest map.

Two notes on reading the table fairly. Most agency prices are quoted excluding VAT, so compare like with like, and if you are not VAT registered the real cost to you is a fifth higher than the sticker. And the growth retainer row is there for the boundary, not as the next rung of the same ladder: our own growth retainers start at £700 a month and include maintenance, but what you are buying at that level is improvement work, and no business should buy it believing it is paying for upkeep alone.

What should each tier include?

The price tells you less than the contents. At any paid tier, a plan that cannot answer yes to these four is overpriced at any figure:

• Updates applied on a schedule, not when someone remembers: the platform, plugins and themes.
• Backups that are stored somewhere else and tested. A backup nobody has ever restored is a hope, not a plan. When we take over an existing site, restoring a backup is one of the first jobs we do, precisely because that is the moment you want to discover it does not work.
• Security patching with a named response time, so a vulnerability announced on Tuesday is not still open in December.
• A human who answers, with the support hours and response time written down.

Standard plans should add uptime monitoring that alerts someone before your customers tell you, and a short monthly note of what was done. Ecommerce plans should add checkout and payment testing after every update round, because a plugin update that silently breaks a checkout is the most expensive kind of quiet. If a plan cannot tell you what happens when something breaks at 4pm on a Friday, that is your answer about its value.

Three questions worth asking any provider before you sign: who owns the backups and where do they live, what is the response time when the site is down rather than merely imperfect, and what happens to your site and its credentials if you leave? The answers tell you more about a provider than the price does.

Why does maintenance matter more on some platforms than others?

If your site runs on a hosted platform such as Shopify, Squarespace or Wix, the platform company patches the core software as part of your subscription. There is still work worth doing, reviewing apps, checking backups of your content, keeping an eye on performance, but the security-critical patching is largely handled. A modest plan, or a capable owner with a checklist, covers it well.

Self-hosted WordPress is a different proposition, and the numbers explain why. Patchstack's State of WordPress Security whitepaper counted 11,334 new vulnerabilities across the WordPress ecosystem in 2025. The reassuring part is where they were: 91% in plugins and 9% in themes, with just six in the WordPress core itself. WordPress is not the problem. Unmaintained plugins are, and Patchstack found the most heavily exploited flaws see their first attacks within a median of five hours of disclosure, while 46% of vulnerabilities had no fix available by the time they were made public.

None of that is a reason to fear WordPress, which remains an excellent platform we build on regularly. It is a reason to treat a plugin-heavy WordPress site without a patching routine as a liability on a timer, and to see the £75 a month plan as insurance priced well below the excess.

What does skipping maintenance cost?

The general picture first: the government's Cyber Security Breaches Survey 2025/2026 found 43% of UK businesses identified a breach or attack in the previous twelve months, which it estimates at around 612,000 businesses. Most of that is ordinary crime like phishing rather than website hacks, but it sets the honest baseline: incidents are normal, not rare.

The website-specific failures tend to be quieter and more avoidable. The classic is the renewal nobody owned. In 2017, the marketing platform Marketo, a business whose entire product is reaching customers online, went dark when its domain auto-renewal failed; a member of the public re-registered the domain and handed it back, and its chief executive publicly blamed human and process error while caching meant some customers were affected for up to two days. In 2020, Microsoft Teams went down for several hours because an authentication certificate was allowed to expire. Billion-pound companies with entire IT departments forget renewals. The lesson for a ten-person business is not that the internet is dangerous, it is that "whose job is the boring stuff" needs a written answer.

That is, in the end, what a maintenance plan is: a named owner for the unglamorous jobs, at a price that only looks optional until the week it does not.

Can you do it yourself?

Sometimes, and a guide that never says so is selling rather than advising.

DIY is a reasonable choice when your site runs on a hosted platform, when a plain brochure site changes rarely, and when you are comfortable spending a little time each month in an admin panel. The real costs are hosting, typically £10 to £50 a month for a business site, a domain at £10 to £30 a year, and your attention. If that describes you, put a monthly reminder in the calendar for updates and a backup check, and spend the saved money elsewhere.

Paying makes sense when the site takes bookings, orders or a meaningful share of your enquiries, when it runs on self-hosted WordPress with more than a handful of plugins, or when the honest answer to "who owns this job" is currently nobody. What you are buying is not mystique, it is the certainty that the dull things happen on schedule, with someone accountable when they do not.

If you are weighing this up alongside bigger questions about the site itself, our guides on whether your website needs a refresh or a rebuild and how to tell if your website is working pair well with this one, and our UK website cost guide covers the build side of the ledger.
