How often should a WordPress site be updated?
There's no single answer, but leaving a WordPress site untouched for months is how small updates turn into a broken site. Here's a realistic schedule for a small business.
If you're asking how often a WordPress site should be updated, the short answer is: check weekly, update at least monthly, and deal with security patches within a few days rather than letting them sit. That's a realistic baseline for most small business sites, not an obsessive schedule.
The longer answer depends on what the site is actually doing. A simple brochure site that barely changes can get away with a lighter touch. A site with forms, bookings, payments, or plugins doing real work needs more regular attention, because there's more that can go wrong and more at stake if it does.
A realistic update schedule for a small business site
Security updates (the ones flagged as critical) should go out within a few days, not left until the next scheduled check. Plugin and theme updates that aren't security-critical can wait for a weekly or fortnightly review. WordPress core updates are usually safe to apply on the same cadence as plugins, once you've confirmed nothing else is likely to conflict with the new version.
The part people skip is testing afterwards. An update applied without checking the site still works properly isn't really finished. At minimum, that means loading the homepage, checking the contact form actually sends, and glancing at the site on mobile.
Why leaving it too long causes more problems, not fewer
It feels safer to leave a working site alone. In practice, the opposite tends to happen. The longer plugins and themes go without updating, the further they drift from what WordPress core expects, and the more likely a single eventual update is to conflict with something else on the site. A site updated in small, regular steps rarely breaks badly. A site updated once a year, all at once, is exactly the situation that tends to knock a plugin sideways or expose a theme that was already quietly out of date.
There's a security angle too. A lot of plugin updates exist specifically to patch a known vulnerability. Leaving updates sitting for months means leaving that hole open for months, on a site that's publicly reachable the whole time.
Where this fits with maintenance and support
None of this needs to be complicated, but it does need to actually happen, on a schedule, with someone checking the result. That's most of what a WordPress support retainer covers, and it's a big part of why WordPress sites keep breaking after updates when nobody owns that job. If you're weighing up what proper cover costs against doing it yourself, how much does WordPress maintenance cost in the UK? has the numbers.
If you want someone keeping your WordPress site updated on a proper schedule and checking it actually still works afterwards, have a look at monthly website support.
Frequently asked questions
How often should WordPress plugins and themes be updated?
Check for updates weekly, and apply them at least monthly for most small business sites. Critical security updates should go out sooner, usually within a few days of release.
Is it bad to update WordPress too often?
Not usually, as long as each update is tested afterwards. The risk isn't updating too often, it's updating without checking the site still works properly, particularly the contact form and any booking or checkout flow.
What happens if I never update my WordPress site?
Plugins and themes drift further out of sync with WordPress core the longer you leave it, which makes each eventual update more likely to conflict with something. It also leaves known security holes open for longer, since a lot of plugin updates exist specifically to patch a vulnerability.
Can I just turn on automatic updates and forget about it?
You can, but automatic updates with nobody checking the result afterwards is how sites end up broken for days without anyone noticing. Automatic updates plus a quick manual check after each one is a safer combination.
