Your boiler needs a service — here's why it matters.

Think of your boiler like your car. You wouldn't drive 20,000 miles without an oil change and expect the manufacturer's warranty to still be valid — and the same logic applies to your boiler. An annual service isn't just routine maintenance; it's the single most important thing you can do to protect your warranty, your safety and your heating bills.

⚠️ Missing a service can void your boiler warranty

Most boiler manufacturers — including Vaillant, Viessmann, Worcester Bosch and Ideal — require annual servicing by a Gas Safe registered engineer as a condition of their extended warranty. Skip a year and you could find yourself with a faulty boiler, no warranty cover and a four-figure repair bill. We'll remind you each year so this never happens.

Our standard annual service follows the industry standard model of servicing by emissions. It will keep the warranty of most younger appliances valid, but appliances over 3 years old may benefit from a full service, your boiler safe and your heating running efficiently — carried out by a Gas Safe registered engineer with a signed service record issued on completion.

Three reasons to never skip a service

Warranty protection

Most manufacturers require annual servicing to keep extended warranties valid. We issue a signed service record every visit.

Lower bills

A well-tuned boiler burns gas more efficiently. Most customers see a measurable drop in energy costs after a proper service.

Safety

A service catches faults early — before they become dangerous. Carbon monoxide leaks and gas escapes are silent risks a service can prevent.

Common questions

Yes — and it matters more than most people realise. Virtually all major boiler manufacturers, including Vaillant, Worcester Bosch, Viessmann and Ideal, specify annual servicing by a Gas Safe registered engineer as a condition of their extended warranty. Skip a service and you risk voiding cover that could be worth thousands. Beyond warranty, regular servicing keeps your boiler running efficiently and safely.

A boiler service is a thorough maintenance check following the manufacturer's schedule. A CP12 (Gas Safety Record) is a legal document certifying that all gas appliances in a rental property are safe — it's a legal requirement for landlords. If you're a landlord, see our dedicated landlord page. We recommend booking both on the same visit to save time and cost.

Our engineers are experienced across all major brands — Vaillant, Viessmann, Worcester Bosch, Ideal, Baxi, Glow-worm, Potterton and many more. We follow manufacturer-specific service schedules, not a generic checklist, so your warranty documentation will always be in order.

A standard annual boiler service typically takes between 45 minutes and an hour. We'll give you a realistic time estimate when you book.
