I get asked about website maintenance more than almost any other question in my web development business. Usually it goes like this: "My developer built my site two years ago. I haven't touched it since. Do I need to pay for maintenance?"
The answer is almost always yes. But most small business owners have no idea what that actually means, what it should cost, or what happens if they skip it.
I run WebDev Wales, a web development studio in Neath, South Wales, and I maintain websites for over 30 small businesses across Wales. Plumbers, cafes, accountants, tradespeople, fitness studios. This is what I've learned about what website maintenance actually involves, what it costs in the UK in 2026, and what happens when you don't do it.
What Website Maintenance Actually Means
The phrase "website maintenance" hides a lot of different work. When a good developer or agency offers a maintenance plan, they are usually covering some or all of these:
Security updates. WordPress, Joomla, Drupal, and every plugin they use release security patches constantly. If you don't apply them, your site becomes a target. A neglected WordPress site can be compromised within weeks of missing an update.
Backups. Daily or weekly backups stored somewhere that isn't on the same server. When something breaks, this is how you recover.
Uptime monitoring. A tool that pings your site every few minutes and alerts someone if it goes down. Without this, you only find out your site is down when a customer calls complaining.
SSL certificate renewal. Most are automated now but not all. An expired SSL certificate means browsers show a scary red warning and customers leave.
Broken link checks. Internal and external links that break over time. Google penalises sites with lots of broken links.
Software updates. PHP version updates, database updates, framework updates. These compound if ignored and eventually force an expensive migration.
Content updates on request. Changing prices, adding staff, updating service descriptions. Usually included up to a limited number of hours per month.
Performance monitoring. Checking page load times and fixing regressions when they appear.
What It Actually Costs in the UK
Prices for website maintenance in the UK vary enormously because the scope varies enormously. Here are honest ranges based on what I see in the South Wales market and discussions with other UK web developers:
DIY Maintenance: £0-£50/month
You handle updates yourself. You need a backup plugin (UpdraftPlus or similar, £40/year for the premium version), a security plugin (Wordfence free tier is decent), and about 2 hours a month to check things.
The hidden cost is your time and the risk if something goes wrong. Most small business owners who try DIY maintenance abandon it within six months because the first time a plugin update breaks their site they realise they have no idea how to fix it.
Basic Managed Hosting with Auto-Updates: £15-£40/month
Services like Krystal, 20i, or WP Engine handle security updates and backups automatically. This covers the bare minimum. You're still responsible for content updates, broken link fixes, and anything that breaks.
Good option if your site is simple and you don't plan to touch it often. Not a real maintenance plan.
Standard Small Business Maintenance: £40-£100/month
This is what most reputable UK agencies charge for a basic small business site. Includes security updates, daily backups, uptime monitoring, SSL management, a few hours of content updates per month, and emergency support when something breaks.
For context, this is what I charge at WebDev Wales. £55/month for a standard brochure site with up to 2 hours of content updates included. It covers about 90% of small businesses I work with.
Premium Maintenance: £100-£300/month
Adds performance optimisation reviews, SEO monitoring, monthly reporting, priority response times, more content update hours, and usually some level of strategic input. Worth it if your website is a major source of leads.
E-commerce Maintenance: £150-£500/month
E-commerce sites are more complex. Payment gateway compatibility, plugin conflicts, inventory sync issues, checkout flow monitoring, abandoned cart system health. The higher price reflects the higher risk. a broken checkout means lost revenue, not just lost visibility.
What Happens If You Skip Maintenance
A few real examples from businesses I've audited:
The plumber who got hacked. Their site was running WordPress 5.8 with outdated plugins. Someone exploited a known vulnerability, injected malware, and Google flagged the site as dangerous. Anyone searching for them got a warning page. It took me three days to fully clean the site, reset compromised credentials, and get Google to remove the warning. Cost to fix: £650. Cost of a £50/month maintenance plan: £300 over six months. Skipping maintenance was the more expensive option.
The cafe with the expired SSL. Their hosting provider auto-renewed the SSL certificate for four years then changed their policy. They stopped auto-renewing and didn't notify the customer clearly. Site went from "Secure" to "Not Secure" on every browser for three weeks before anyone noticed. Reviews started dropping because customers thought the site was fake. Fix took 20 minutes. Damage took months to recover from.
The accountant whose site disappeared from Google. Their site was hosted on a cheap shared server that kept going down. Brief outages several times a week, sometimes lasting hours. Google's crawlers kept hitting a down site and eventually de-indexed pages. They lost about 40% of their organic traffic over four months. Nobody was monitoring uptime so nobody noticed until enquiries dropped off a cliff.
How to Tell If Your Current Maintenance Is Worth Paying For
If you're already paying for maintenance and wondering if it's good value, ask your provider for:
A list of software/plugin updates applied in the last 3 months. If they can't produce this, they probably aren't doing updates.
Access to your latest backup. You should be able to download it. If they control the only copy and won't give you access, that's a hostage situation waiting to happen.
Uptime reports for the last 30 days. A good provider will have this automated and will share it freely.
Evidence of SSL certificate monitoring. Screenshot of their monitoring dashboard or a confirmation email when it last renewed.
If your provider can produce all four, you're in good hands. If they can produce none of them, you're paying for nothing.
The Honest Take
Website maintenance is unglamorous and invisible when it's done well. If your website hasn't gone down, hasn't been hacked, and is still ranking on Google, your maintenance is probably working. It's the kind of cost that feels pointless until it isn't.
For a typical UK small business, expect to spend £40-£100/month for proper maintenance. Less than that and someone is cutting corners. Significantly more than that and either your site is complex or you're being overcharged.
If you're in Wales and you're unsure whether your current setup is adequate, happy to take a quick look. No obligation, just honest feedback.
