Boiler servicing

The annual service most manufacturers ask for, and the one that catches the faults that turn into a January breakdown.

A gas boiler is meant to be checked once a year. It keeps the appliance burning cleanly and safely, it is usually a condition of the manufacturer's warranty, and it catches the small faults that turn into a breakdown in January. We service domestic gas boilers across Nottingham and the surrounding area.

What happens on the visit

We start with the boiler where it stands: controls run up, the flue terminal and its route checked outside, the meter and gas pipework looked over, and ventilation checked if the appliance sits in a cupboard or a room that needs it. Then the casing comes off.

Inside, we inspect the combustion chamber, heat exchanger, burner and injectors, clean what needs cleaning and check the seals. We run a flue gas analysis with a calibrated analyser and read the combustion figures against the manufacturer's, check the gas rate and working pressure, and test the appliance for gas tightness. Condensate trap, expansion vessel charge, system pressure and the safety devices are all checked before the casing goes back on.

Older appliances, boilers built into fitted units and anything needing a real clean take longer than a boiler that is accessible and in reasonable condition.

Why an annual service matters

Warranty comes first for most people. Manufacturers generally require a documented annual service to keep cover in place, recorded in the benchmark book or on a service record, so it is worth checking what your paperwork says. If the boiler has been missed for a year or two, have it looked at anyway.

Then safety. A boiler burning badly, or a flue that has cracked or pulled at a joint, is not something you would necessarily notice from the kitchen. The combustion readings and the flue inspection are the parts of the service that find it.

Most breakdowns also give notice. Pressure dropping over a fortnight, a condensate trap silting up, a diverter valve starting to stick, a pump running noisy: all of it shows up in a service while it is still a small job.

If we find a fault

Finding something does not mean work starts. We tell you what it is, what it means for the boiler and what it would take to put right, and you decide. Pricing is open and agreed with you before anything is done, on the same rates and procedures explained when you booked.

If an appliance is genuinely unsafe we have to say so and explain how it has been classified. Turning off or capping an unsafe appliance needs your permission. You are left with the warning notice and a clear account of what has to happen before it can go back into use. Where a repair needs parts, we quote for the work and book it in with you.

Common questions

How long does a boiler service take?

It depends on the boiler. An accessible appliance in reasonable condition is straightforward. A boiler boxed into a fitted cupboard, one that has gone a few years without a service, or one where the burner and heat exchanger need a proper clean all take longer. The checks are worked through in full either way.

Do I need a service if the boiler is working fine?

Yes, for two reasons. Manufacturers commonly make a documented annual service a condition of the warranty, so it is worth reading what your own paperwork asks for. And the checks that matter most for safety, the combustion readings and the flue inspection, test things you cannot see or hear from the room.

What do I get at the end of the visit?

A written record of the checks made and the readings taken, and the benchmark book or service record filled in if your boiler has one. If something needs attention you get it in plain terms: what it is, whether it can wait, and what putting it right involves. Keep the record with your boiler paperwork, as a warranty claim will normally depend on being able to show the service history.

Is a service the same as a landlord gas safety certificate?

No. A CP12 is a safety check on the gas appliances, pipework and flues in a rented property, while a service is the strip-down, clean and adjustment that keeps one appliance running properly. Many landlords have both done on the same visit. If you want both, say so when you book so the right amount of time is allowed.
