Gas boiler service, Bristol

Keep your gas boiler safe, efficient and reliable.

Annual boiler servicing is an essential way to keep your gas boiler in peak condition and avoid serious, long-term breakdowns. Our fully qualified Gas Safe registered engineers carry out a range of tests and checks to make sure your boiler is working as safely and efficiently as possible.

Gas boilers need regular servicing to keep operating safely. A service involves our experienced heating engineers inspecting and maintaining the boiler’s key components to keep it in good working order. Having your gas boiler serviced every 12 months can extend its lifespan, minimise the likelihood of future faults and is often a requirement of your boiler’s guarantee or warranty.

Working throughout Bristol and the surrounding areas, we service all common makes of gas boiler. We also provide boiler repairs, gas boiler installations and boiler servicing for landlords, including the annual Gas Safety Certificate.

What’s included

What does a gas boiler service include?

Our engineer removes the boiler casing and works through a full set of safety and efficiency checks. Here’s what a gas boiler service covers.

Flue gas analysis

We test the flue gases to check the boiler is burning gas cleanly and safely, and that combustion products are leaving the property as they should.

Gas pressure test

We check the gas pressure at the boiler, and the fan pressure, so the burner gets the right supply and runs at its designed efficiency.

Ignition and electrics

We test the ignition probe and replace it if it has degraded, and check the boiler’s electrical connections are sound and safe.

Heat exchanger and seals

We clean the main heat exchanger and fit new seals where required, keeping heat transfer efficient and the combustion chamber sealed.

Condensate trap and filter

We clean the condensate trap, a common cause of winter lockouts when it blocks or freezes, and clean the system filter.

Expansion vessel and water

We check the expansion vessel pressure and test the system water’s pH, re-inhibiting it if required. On request, we can check the wider central heating system too.

Gas safety

Don’t skip the service. Know the warning signs.

A badly maintained gas boiler can leak carbon monoxide, a poisonous gas you can’t see or smell. An annual service is the best way to catch a problem early. Between services, keep a working carbon monoxide alarm near the boiler and call us if you notice anything unusual.

[VERIFY RESPONSE TIMES — hours confirmed by AMW 14 Oct (Mon–Fri 7am–5pm, Sat 7am–12pm); copy still makes no same-day or emergency response promise until AMW confirms one]

Call a Gas Safe engineer if you notice:

Smell gas? Don’t use electrical switches or naked flames. Open windows, turn off the gas at the meter if you can, leave the property and call the National Gas Emergency Service on 0800 111 999.

On the day

What happens during your gas boiler service.

01

Get ready

Clear the area around the boiler so the engineer can reach it and the pipework. If you’re confident doing so, switch the boiler off about 30 minutes before we arrive so it can cool.

02

Inspect and clean

We remove the boiler casing, inspect the components inside and clean the heat exchanger, condensate trap and filter.

03

Test and measure

We run the flue gas analysis and the gas, fan and expansion vessel pressure checks, and test the ignition and electrics.

04

Report and advise

Most services take around 30 to 40 minutes. If we find a fault, we show you, explain your options and can quote for the repair there and then.

We strongly advise having your gas boiler serviced at least once a year to keep it running safely and efficiently. During the annual service, our fully qualified Gas Safe registered engineers carry out a thorough inspection, finding and fixing small faults before they escalate into long-term problems. An annual service also keeps any boiler guarantees or warranties you have in place valid, and many home insurance policies expect one too.

Most of the time, a gas boiler service takes around 30 to 40 minutes. The engineer works through a series of safety checks and measurements to make sure everything is working as it should. That includes removing the boiler casing to inspect and clean the components inside. If we find something that needs more attention, we’ll explain what it is before doing anything further.

A couple of simple preparations help. Make sure the area around the boiler is clear, so your engineer can easily inspect the boiler and its pipework and remove the boiler casing. If you’re confident doing so, you can also switch the boiler off around 30 minutes before your appointment. This lets the key components cool down ahead of time, so the service can start straight away.

If our engineer finds a fault or issue, they’ll show you the problem, explain what it is and talk you through your options for repairing or replacing components. They can give you a quote for any repair work there and then, on the same day, so you know exactly where you stand. Find out more about our boiler repairs.
