WordPress maintenance checklist (UK): what you must do monthly

WordPress Maintenance Security Performance UK

WordPress maintenance is the difference between a site that quietly works for years and a site that breaks at the worst possible time (often after an update you forgot you ran).

This is a practical checklist you can use monthly — plus what to check after updates.

Monthly WordPress maintenance checklist

1) Updates (but safely)

  • Update plugins (start with low-risk ones)
  • Update theme (and check WooCommerce overrides if you use them)
  • Update WordPress core
✅ Best practice: take a backup first, update in small batches, test key flows after.

2) Backups (verify, don’t assume)

  • Confirm daily backups exist
  • Confirm you can restore (at least once per quarter)
  • Store backups off-server if possible

3) Security basics

  • Remove unused plugins/themes
  • Check admin users (remove old accounts)
  • Enable 2FA for admin accounts (recommended)
  • Review login attempts / WAF logs if you have them)

4) Uptime + error monitoring

  • Uptime monitor (even a basic one)
  • Check for recent 500 errors / “critical error” emails
  • Scan WooCommerce logs if you run ecommerce

5) Performance quick checks

  • Run a quick Lighthouse test (Home + a key landing page)
  • Check image sizes (hero images are common offenders)
  • Confirm caching is working (but not caching checkout)

6) Database housekeeping (light touch)

  • Remove old post revisions (carefully)
  • Clean expired transients
  • Check for plugin tables growing unexpectedly

After every update: what to test

Don’t update and walk away. Test the flows that matter:

  • Contact form: submit and confirm email arrives
  • Checkout (if WooCommerce): add to cart → checkout → payment
  • Core pages: Home, Services, Contact (layout + speed)
  • Admin: can you edit content without errors?
✅ A 2-minute test now can prevent a week of “why did leads stop?” later.

What UK businesses often forget

  • Renewals: domain, SSL, hosting, premium plugins
  • Email deliverability: SMTP still working after changes
  • Tracking: GA4/GTM still firing after theme/plugin updates

When to get help

If you’re updating and something breaks, the risk is usually:

  • plugin conflicts
  • theme overrides
  • server/PHP version mismatches
  • custom code not compatible with updates
