Most businesses underestimate what it takes to maintain a website properly. In the UK, you will often see website maintenance advertised for around £50 per month. In most cases, that simply means a system runs automatic WordPress plugin updates and sends a report afterwards. There is usually no testing, no staging environment and no real checking if something breaks.
Proper website maintenance is different. For example, as part of our website maintenance packages , updates are applied carefully, the site is checked afterwards and security and performance are monitored over time.
Understanding what businesses typically pay helps set realistic expectations about the level of support your website actually needs. In this article, we explain what website maintenance typically costs, what affects the price and what businesses should expect to receive for their money.
Most professional website maintenance services are based on allocated hours each month, rather than a flat fee for unlimited work. For example, a business might retain 2, 5 or 10 hours per month depending on how much support their website needs. Those hours are then used for things like updates, security checks, fixes, performance improvements or small development tasks.
At ALT Agency, our website maintenance work is typically delivered through monthly retainers charged at £90 per hour, with a defined number of hours allocated each month. Unused hours roll forward for up to three months, which gives clients flexibility if priorities change or work slows down temporarily. Our retainers also run on a three month minimum term, after which clients can cancel with one month’s notice.
Website costs vary widely depending on what you are building. As we explained in our guide on how much a website costs , a simple brochure site and a complex platform sit in completely different categories.
The same applies to how much website maintenance costs per month in the UK in 2026. Monthly costs usually reflect how many hours of support and monitoring a website needs, along with the complexity of the platform itself.
At the cheaper end, maintenance is usually limited to automated plugin updates. A system runs the updates and sends a report showing whether they succeeded. In many cases, the updates are applied directly to the live site without being tested first.
For very small websites that rarely change, this can be enough. But if something breaks after an update, there is often no process in place to catch it quickly.
This is where proper website maintenance usually starts. Updates are applied more carefully and checked afterwards to make sure the site still works as it should. Security monitoring is usually included, along with basic performance checks and regular reporting.
Most businesses move into this range once their website starts generating enquiries or playing a bigger role in marketing.
Higher maintenance retainers are common for ecommerce websites or platforms that receive a lot of traffic. Updates are managed carefully, security is monitored closely and performance is reviewed regularly. There is also usually development time available to fix issues or make improvements.
For businesses that rely heavily on their website, this type of website maintenance helps reduce the risk of downtime, security problems or performance issues affecting sales.
Website maintenance costs vary because websites themselves vary significantly in complexity and risk. A few common factors usually determine how much maintenance a site needs:
Website size and structure: A simple website with five or ten pages is relatively easy to maintain. A large site with hundreds of pages, custom templates or product listings requires a much more thorough testing process when updates are applied.
Plugins and integrations: Most WordPress websites rely on plugins for things like forms, bookings, ecommerce, analytics and marketing tools. Each of those plugins and WordPress API integrations introduces another dependency. When updates are applied, those systems need to be checked to make sure they still work together properly.
How important the website is to the business: A website that generates the occasional enquiry carries less risk than one processing orders every day. If the website is central to sales, marketing or operations, maintenance usually needs to be more proactive to reduce the chance of downtime or technical problems.
Security risk: As WordPress is widely used, it is also a common target for automated attacks. For example, outdated plugins, insecure themes or weak configuration can create easy entry points for attackers. We explain the most common threats and practical ways to protect your site in our guide on how to keep your WordPress site secure , but regular maintenance helps identify vulnerabilities like these early. If you have been hacked, our hacked website repair service can quickly restore your site and secure it against future attacks.
Response times: Some businesses only need occasional help and are happy to wait a day or two for support. Others need a fast response if something goes wrong.
A good maintenance service follows a clear process to keep the site stable, secure and performing properly. That usually includes a few key actions:
Updates handled properly: WordPress core, theme and plugin updates need to be applied carefully. Updates should normally be tested in a staging environment before they go live. This reduces the risk of updates breaking layouts, functionality or integrations.
Checking the site after updates: Once updates are applied, the main parts of the site should be checked properly. Forms, navigation, templates and key user journeys need to be reviewed to make sure everything still works.
Basic security checks: Website maintenance should also include regular checks for security issues. That means monitoring for known vulnerabilities, running malware scans and fixing weak points before they become a problem.
Performance monitoring: Websites tend to slow down over time. Plugins add extra database queries, images get heavier and small inefficiencies start to build up. Regular checks help identify performance problems early so they can be fixed before they affect users or search rankings.
Clear monthly reporting: Finally, a maintenance service should show you what has actually been done. A simple report should outline the work completed, any issues found and any improvements that are recommended.
If your website generates enquiries or sales, it needs proactive maintenance on a monthly basis. Website maintenance should keep your site stable, secure and running properly so small technical issues do not turn into bigger problems later.
