FAQs: Boiler Maintenance

Do I need a boiler service every year?

Annual servicing is recommended to help keep your boiler safe, efficient, and reliable. It can also support warranty requirements for newer boilers. We’ll advise on the right service interval for your boiler type and usage.

What does a boiler service include?

A typical service includes safety checks, inspection of key components, cleaning where required, performance testing, and a written record of what was checked and any recommendations. The exact steps depend on the boiler model and manufacturer guidance.

How much does a boiler service cost?

Pricing depends on boiler type, accessibility, and whether it’s a straightforward service or there are faults to diagnose. We’ll confirm the service price in advance and discuss any repair costs separately if issues are found.

My boiler pressure keeps dropping — is that something you can check during a service?

Yes. We can check for common causes such as system leaks, a faulty pressure relief valve, or expansion vessel issues. If a repair is needed, we’ll explain options and costs before doing any additional work.

Should I get my heating system serviced as well as the boiler?

In many homes, yes. Boiler servicing focuses on the appliance, while system performance depends on pipework, radiators, inhibitors, and sludge levels. We can recommend checks like system balancing, a powerflush (where appropriate), or water quality testing based on symptoms and age.

Do you service boiler controls, smart thermostats, and heating timers?

Yes. Controls and thermostats can affect comfort and running costs. We can check configuration, diagnose common issues, and advise on upgrades if controls are outdated or unreliable.
