Strange noises, no hot water or a pilot that won't stay lit? Start here
Most boilers give a warning before they fail. Kettling or banging from the heat exchanger, radiators that stay cold at the bottom, pressure that keeps dropping, a yellow or orange flame, or black marks around the casing are all worth getting looked at. So is a boiler that has started cutting out when the weather turns cold.
We look after gas boilers, whether combi, system or regular with a separate cylinder. A repair visit starts with finding the actual cause, rather than swapping parts and hoping. Typical faults include failed pumps, diverter valves, faulty thermistors, blocked condensate pipes, ignition problems and sludge in the heating circuit.
A service is a different job. It's a planned check that keeps the boiler efficient and safe, and it often catches small faults before they turn into a no-heating call in January.
If a repair isn't worth the money, we'll say so and talk you through the options for replacement. You make the decision, and we won't push a new boiler when a repair will do.

What happens on the day, from the first question to the last test
Whether it's a breakdown or a yearly service, the visit follows the same disciplined order.
- 1
Talk it through and look it over
We ask what the boiler has been doing, when it started and whether anything has changed. Then we check the visible condition: casing, pipework, flue, signs of leaks, pressure gauge and the controls.

Find the cause before touching a part
We test the boiler through its cycle and work out why it's failing. If a part is needed, we tell you what it is, what it does and what it will cost before we fit it.

Service or repair, done to the manufacturer's instructions
On a service we inspect and clean the key components, check the condensate trap, seals and flue, and test the safety devices. We use a flue gas analyser to check combustion is clean and efficient. Repairs follow the manufacturer's instructions and gas safety regulations.

Test, record and explain
We run the boiler and heating again to confirm everything works, then show you what we found. You get a clear explanation of any advice or follow-up work, in plain English, and a written record of the visit.
A boiler engineer who explains the problem and the bill
Handing over the keys to your heating is a big ask. Here's what we do to earn it.
Gas Safe registered, properly insured
Anyone working on a gas boiler must be on the Gas Safe Register by law. We are, and we carry public liability insurance. You can check any engineer's registration on the Gas Safe website before they start.
Honest about repair versus replace
Age, how often it fails, whether parts are still available and how efficiently it runs all matter. We lay out the facts, then leave the decision with you.
Pricing explained before work starts
Cost depends on the fault, the parts needed, the make and age of the boiler and how easy it is to reach. We quote before we fit anything, so there are no surprises on the invoice.
Work guaranteed for 5 years
We stand behind our workmanship for five years. Replacement parts may also carry their own manufacturer's warranty, which we'll point out when it applies.
Sensible aftercare
We'll tell you your boiler's correct pressure, what to check between services and when to ring us. We also recommend a working carbon monoxide alarm in any home with a gas appliance.
What boiler customers have told us
Brilliant service from start to finish. Our boiler stopped working and the team came out quickly, diagnosed the problem and had everything sorted. Really friendly and professional.
Excellent experience. Turned up on time, explained everything clearly and the pricing was exactly as quoted. Would definitely recommend PlumbTap.

Boiler repair and servicing: your questions answered
How often should my boiler be serviced?
Once a year. It keeps the boiler running efficiently and safely and can pick up faults early. Many manufacturers also require an annual service by a Gas Safe registered engineer to keep the warranty valid, so check your paperwork.
Is a boiler service the same as a landlord gas safety check?
No. A service checks and maintains the boiler. A landlord gas safety record is a legal safety inspection of all gas appliances and flues in a rented property. They are separate jobs with different paperwork. If you're a landlord, mention it when you call so we can book the right visit.
How long does a boiler service take?
A straightforward service on one boiler usually takes about an hour. Older systems, awkward locations or faults found along the way can take longer. We'll tell you before we carry on with anything extra.
Should I repair or replace an older boiler?
It depends on the fault, the age of the boiler, whether parts are still available and how efficient it is. If it's a one-off fault on a sound boiler, repair usually makes sense. If it keeps failing or parts are scarce, replacement may cost less in the long run. We'll give you a straight answer.
My boiler keeps losing pressure. What should I do?
Check the pressure gauge and, if your manual shows how, top it up using the filling loop. If it keeps dropping, there's probably a leak or a faulty expansion vessel or pressure relief valve. Don't keep topping it up. Get it checked, as water loss can damage the boiler.
What should I do if I smell gas?
Turn off the gas at the meter if it's safe to do so, open windows and doors, don't use switches or naked flames, and leave the property. Call the National Gas Emergency Service on 0800 111 999 straight away. Don't wait for a repair booking.
