Booking your annual boiler service? Smart move! A well-maintained boiler keeps your home warm, your energy bills lower, and your hot water flowing all year round. At DTS Plumbing & Heating, we’re here to make the process easy, efficient, and maybe even a bit enjoyable (yes, biscuits are involved).

Here’s everything you need to know about what happens during a boiler service—and how you can help us help you on the day.


Before We Arrive – A Bit of Prep Makes All the Difference

To help things go smoothly, here’s what you can do before we knock on the door:

  • Clear the way – make sure there’s easy access to the boiler and any relevant controls. No need to deep clean, just keep the clutter at bay.
  • Gas meter check – we may need to access this, so please make sure it’s not blocked by bins, boxes, or last year’s DIY project.
  • Background music? Sure! – something mellow is perfect. Our engineers have been known to hum along to a bit of Fleetwood Mac.

And of course:

  • Stick the kettle on – we’d never demand a brew, but we’re not likely to turn one down either.
  • Biscuits welcome (strongly encouraged) – Rich Teas, Hobnobs, or a wildcard like a Viennese Whirl? We don’t judge.

What We Actually Do During a Boiler Service

We get it—you want to know what you’re paying for. Here’s what’s included in your boiler service:

  • Visual inspection – we check for signs of leaks, corrosion, or anything that looks a bit “off”.
  • Internal check – we remove the boiler casing and take a close look at key components like the burner, heat exchanger, and seals.
  • Cleaning – we clean any parts that need a little TLC to keep everything ticking along.
  • System testing – we test flue emissions, gas pressure, safety devices, and controls to make sure your boiler is running efficiently and safely.
  • Paperwork – we fill out your logbook, let you know how everything looks, and offer any advice if we spot something worth keeping an eye on.

Got an Older Boiler? Here’s What to Know

Older boilers have served you well—but just like a favourite old car, sometimes a service can highlight parts that are on their last legs.

After a service, there’s a small chance that:

  • worn-out part might pack in once it’s been cleaned or tested. (Sometimes things that were just hanging on call it quits.)
  • Replacement parts may not be readily available for very old models. We’ll always do our best to track things down or suggest suitable alternatives.

We’ll always keep you in the loop. No pressure, no pushy sales—just honest advice and clear options if anything needs attention.
