Will a Service Fix My Boiler?

Is your boiler acting up — no heat, weak hot water, or strange banging sounds? You might be wondering: will a service fix it, or do I need a proper repair?

Here’s the honest answer: it depends. Let’s break down when a boiler service can solve the problem — and when it’s time to call for a repair instead.

What’s Included in a Proper Boiler Service?

A thorough service is more than just a five-minute pressure check. We always include:

• A full visual inspection of the boiler and flue
• Gas pressure and combustion checks
• Cleaning of key components (burner, heat exchanger where accessible)
• Safety checks on seals, sensors and the expansion vessel
• Checking system pressure, inhibitor levels, and pipework
• Logging service records and flagging potential issues

It’s all about keeping your boiler safe, efficient and catching small issues before they become big problems. Regular servicing can also help extend the life of your boiler.

Can a Service Fix an Issue?

Yes — if the problem is minor or caused by build-up, a service might be all you need. For example:

• Your boiler’s noisy due to sludge or air in the system
• Efficiency has dropped due to dirt on the burner
• The pressure keeps dropping from minor airlocks
• Your smart thermostat isn’t syncing properly

We’ve seen plenty of cases where a thorough service brought a misbehaving boiler back to life — without needing any parts replaced.

When a Service Won’t Fix the Problem

If your boiler has a deeper fault, it’ll need a repair — not just a service. Signs you need a boiler repair include:

• Error codes or your boiler won’t switch on
• No heating or hot water at all
• Visible water leaks or pressure dropping constantly
• Strong smells or loud banging/clanging sounds

In these cases, a service won’t fix the issue — it’ll just confirm that there’s a fault that needs attention.
