Boiler Repair in West London & North West London
Boiler repairs in West and North West London cover fault finding, leaks, pressure loss, ignition faults, pump problems, thermostat issues and no heating or hot water.
The Happy Heating Co sends Gas Safe registered engineers to diagnose the fault, explain what has failed and repair it where it is safe and sensible to do so. A few simple checks, like topping up low pressure, can be homeowner jobs. Anything involving gas, combustion, flues, seals or internal boiler parts must be handled by a Gas Safe engineer.
If your boiler has locked out, is leaking, keeps losing pressure or is showing an error code, we can usually get you back up and running fast.

Covering West & North West London
If your boiler's doing any of this, we can help
We repair common boiler faults across West and North West London, including Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm and more.
No heating or hot water
Usually caused by a valve, pump, thermostat, pressure or ignition fault. We diagnose the issue and explain the repair before work begins.
Leaking or dripping boiler
Water around or under your boiler can point to a seal, valve, pipework or heat exchanger issue. We find the source and explain the safest next step.
Boiler losing pressure
If your boiler keeps dropping below 1 bar or needs topping up often, there may be a leak, expansion vessel issue or pressure relief valve fault.
Boiler keeps switching off
A boiler that locks out or cuts out repeatedly may have low pressure, poor circulation, an airlock, blocked condensate pipe or faulty sensor.
Banging or gurgling
Kettling, banging and gurgling can be caused by trapped air, sludge, circulation problems or a sticking pump. We check the system and explain the fix.
Fault codes or ignition problems
If your boiler shows an error code or will not fire up, we read the fault, test the likely cause and quote clearly before carrying out the repair.
If you smell gas, do not book online.
If you smell gas, turn off the gas at the meter if safe, open windows, avoid electrical switches and call the National Gas Emergency Service on 0800 111 999. Contact us afterwards for boiler repair advice.

Which boiler brands do you work on?

What if my boiler cannot be repaired?
If your boiler cannot be repaired safely or economically, we’ll explain why and talk you through your options. We do not push unnecessary replacements. If a new boiler is the better long-term choice, we can provide a clear replacement quote.
Are boiler repairs guaranteed?
Yes. Our labour is guaranteed for 12 months on boiler repairs. If manufacturer parts are fitted, those parts will usually be covered by the manufacturer’s own warranty terms. We’ll explain what is covered before work is completed.
Are your boiler repair engineers Gas Safe registered?
Yes. Boiler repair work is carried out by Gas Safe registered engineers. Our Gas Safe registration number is 657972.
What should I do if I smell gas?
If you smell gas or suspect a gas leak, do not use electrical switches, flames or appliances. Open windows if safe to do so, leave the property and call the National Gas Emergency Service on 0800 111 999. We do not treat suspected gas escapes as a normal boiler repair booking.
