Website maintenance costs in the UK are one of the least transparent parts of buying a website. Build prices get compared endlessly. The monthly fee that follows, which over three or four years often adds up to more than the build, tends to get waved through with a quick 'that includes hosting and support'.
This guide breaks down what maintenance actually is, what small businesses typically pay for it, which parts are genuinely needed and which are padding, and how to work out whether a plan you have been quoted is fair.
What does website maintenance actually cover?
'Maintenance' is a loose word, so the first job is to split it into its parts. Most of it is invisible when it works and very visible when it does not.
- Software updates: the content management system, theme and plugins (on WordPress), or the framework and libraries on a custom build. Out-of-date software is the most common way small business sites get hacked.
- Backups: a copy of the site and its data taken on a schedule, stored somewhere other than the server itself, and occasionally test-restored so you know they work.
- Uptime monitoring: an automated check every minute or few minutes that alerts someone if the site goes down.
- SSL certificate: the padlock. Free certificates renew automatically every few months; if renewal fails, visitors see a security warning.
- Hosting: the server the site runs on. Often bundled into maintenance, sometimes billed separately.
- Fixes: something breaks after an update, a form stops sending, a page layout collapses on a new phone.
- Content changes: new photos, updated prices, a new service page, opening hours over Christmas.
- Checks: forms tested, speed checked, broken links found, Search Console errors looked at.
Website maintenance costs by type of plan
These are typical UK market ranges for a small business site at the time of writing, not quotes. The spread is wide because the word covers everything from an automated backup to a developer on call.
| Arrangement | Typical cost | What you usually get | Who it suits |
|---|---|---|---|
| DIY on a website builder | Included in the £10–£40 a month subscription | Platform handles updates, hosting and security; you do all content changes | Owners with time who are happy with a template |
| DIY on self-hosted WordPress | £5–£30 a month hosting, plus plugin licences | You run updates and backups yourself, and fix what breaks | Owners who are comfortable with the technical side |
| Freelancer, pay as you go | £30–£75 an hour, often a one-hour minimum | Work done when you ask; nothing happens in between | Sites that rarely change and are low risk |
| Small business care plan | £30–£150 a month | Updates, backups, monitoring, hosting and some monthly changes | Most small businesses |
| E-commerce care plan | £100–£500 a month | As above, plus checkout testing, payment and stock integrations | Online shops taking real orders |
| Agency retainer | £200–£1,000+ a month | A block of developer or marketing hours, reporting, priority support | Larger sites with frequent changes |
Why some sites cost more to maintain than others
Two sites that look identical can have very different maintenance bills. The main drivers are how the site was built and how much moving machinery it has.
A WordPress site with twenty plugins is the classic example. Each plugin is written by a different developer and updated on its own schedule. Updating one can break another, so a careful maintainer updates, then checks the site, then fixes what went wrong. That checking is the real cost. A site with three plugins needs a fraction of the attention.
A hand-built site with no plugin ecosystem has less to update, but when it does need changing, it needs the person or team who understands the code. That is fine if the builder is the one maintaining it, and awkward if they are not.
- Number of plugins, apps or third-party integrations.
- Whether the site takes payments or stores customer data. More risk means more care.
- How often you want content changed.
- How fast you need a response when something breaks: next week, next day or within the hour.
- Whether hosting is included, and what kind.
What is worth paying for, and what is padding
The parts of maintenance that protect you are updates, off-server backups, monitoring and someone responsible for fixing things. If a plan covers those properly, it is doing its job.
The padding tends to sound impressive and change nothing. Be wary of these as the main selling point of a plan:
- A monthly 'SEO report' that shows rankings but never results in anything being changed on the site.
- 'Security scanning' that emails you a list of warnings but does not include fixing them.
- Unlimited changes with no stated turnaround time. Unlimited at a two-week wait is not the same as two changes done in a day.
- 'Premium' hosting on a site that gets a few hundred visitors a month. A small local site does not need an enterprise server.
- Charging separately for the SSL certificate. Free, automatically renewing certificates have been standard for years.
Pay as you go or a monthly plan: which is cheaper?
It depends on how often you need anything. Take a freelancer at £50 an hour and a care plan at £60 a month. If the site needs a morning of updates and fixes once a quarter and you never change content, pay as you go costs roughly £200–£400 a year against £720 for the plan.
Now add real life: new photos in spring, a price change, a new service page, a broken form in August that costs you a week of enquiries before you notice. Once you want even one or two small changes a month, a plan usually works out cheaper, and the monitoring means problems get caught before customers find them.
The hidden cost of pay as you go is that nothing happens unless you ask. Updates get skipped because you forget or do not want the bill, and skipped updates are how small sites end up hacked.
Questions to ask before you sign a maintenance plan
- Exactly what is included each month, in writing: updates, backups, monitoring, hosting, number of changes.
- How often backups run, where they are stored, and when one was last test-restored.
- What counts as a small change and what gets quoted separately.
- How fast they respond to a site-down emergency, and whether that includes evenings and weekends.
- Whether the plan has a minimum term, and the notice period to leave.
- What you get when you leave: your domain, your content, a copy of the site.
- Who actually does the work. The person you spoke to, a junior, or an outsourced team.
How we handle maintenance
Every Nerdsharks site includes maintenance in the monthly fee rather than as an extra: hosting, SSL, 24/7 uptime monitoring, daily backups, out-of-hours emergency fixes and two small changes a month done for you. We build without a pile of third-party plugins, which keeps the maintenance load, and the risk, low. On our Monthly plan that is £99 a month after a £299 setup fee; if you pay for the build upfront it is £49 a month. Put that next to any other quote using the questions above.
