Your agency charges to maintain your site, then charges again when their updates break it

What the maintenance retainer is supposed to cover

A WordPress maintenance retainer usually covers three things: keeping the software up to date, fixing things when they go wrong, and making sure the site stays online. That is the whole pitch. It is why agencies charge between £100 and £200 a month for it.

If updates are included and fixes are included, then an update that causes a fault is covered work. The agency runs the update. The update breaks something. The agency fixes it. That is one job, not two.

The moment they send you a separate invoice for that fix, the retainer has stopped being maintenance. It has become a fee for the privilege of being on their list.

Why WordPress updates keep breaking your site

WordPress sites are built from layers of small add-on programs called plugins - one for the contact form, one for the booking calendar, one for the photo gallery, and so on. Every plugin is written by a different person. When WordPress itself updates, or one of the plugins updates, the others sometimes stop working with it.

This is not a freak event. It is the predictable, weekly behaviour of a WordPress site with ten or fifteen plugins on it. Any agency that has run WordPress sites for more than a year knows this happens. They build their pricing around it.

• WordPress core releases an update - other parts of the site stop talking to it
• A plugin author updates their plugin - it clashes with another plugin
• The theme (the design layer) updates - the layout breaks on mobile
• Two plugins update on the same day - nobody knows which one caused the crash

The honest fix is to use fewer plugins, test updates before applying them to the live site, and absorb the occasional repair as part of the retainer. The profitable fix is to apply updates without testing, wait for something to break, and bill the client for the rescue.

The double billing pattern explained

Here is what the pattern looks like from your side. You pay £150 a month. An email arrives saying "we have applied the latest WordPress updates to keep your site secure." A week later your contact form has stopped sending or your booking page is showing an error.

You ring the agency. They tell you it is a plugin conflict caused by the recent update, and the fix will be £180 plus VAT. You pay it because the site is broken and you need it working.

The unspoken arrangement is that the retainer pays for the routine work and the breakage pays for the bonus.

Two months later it happens again. Different plugin, same invoice. Over a year you have paid the retainer twelve times and the "emergency fix" four or five times on top. The total comes out closer to £2,500 than the £1,800 you thought you signed up for.

Questions to ask your agency before paying again

Before you pay the next "update broke the site" invoice, ask them these in writing:

• What does my monthly retainer include, line by line?
• If you applied the update that caused the fault, why is the fix billed separately?
• Do you test updates on a copy of my site before applying them to the live one?
• How many plugins does my site use, and which ones could be removed?
• Can you give me a list of every extra invoice I have paid in the last twelve months on top of the retainer?

The answers will tell you everything. If they cannot itemise the retainer, the retainer is not really for anything specific. If they do not test updates first, they are using your live site as the test environment and charging you when the test fails.

How to stop the cycle for good

You have two routes. Stay on WordPress with someone who actually tests updates before applying them, or move to a site that does not need weekly updates in the first place.

Most small business sites - a plumber in Leeds, a therapist in Bristol, a cafe in Sheffield - do not need WordPress at all. They have five or six pages, a contact form, and a photo gallery. A hand-built site of plain web pages does the same job, loads faster, and has nothing to update. No plugins means no plugin conflicts. No conflicts means no surprise invoices.

If you do need a content system because you write regular blog posts or update prices often, the answer is fewer plugins and tested updates - not a bigger retainer.

This is the gap I built SkipTheAgency to fill. The Maintained plan is £65/month and covers updates, fixes, and the things that go wrong because of updates - all of it, no separate invoices when something an update touched stops working. Most small business sites I take on get rebuilt without WordPress entirely, which removes the breakage problem at the root. Migration from your current agency is free.
