Boiler Repair Bath

We repair boilers in Bath when the heating stops, the pressure drops or the hot water runs cold. Our engineer finds the actual fault first, explains it in plain English, then gives you a fixed price before any parts are ordered or fitted.
Boiler repair in Bath
Boiler repair in Bath is mostly a winter call, whether it is a flat on the Upper Bristol Road with no hot water or a house up Widcombe Hill where the radiators have gone cold. If you live near the Rec, mention any match day when you ring so we can plan where to park. Up on Claverton Down, a student let with a dead boiler over the holidays can turn cold and damp fast, so report a fault before everyone heads off. If you rent and repairs are dragging on, the council's advice on damp, mould and cold homes sets out where to get help.
We fix boiler breakdowns across Bathwick, Twerton, Combe Down and Bathampton.
Homes and heating systems
Breakdowns here tend to involve combis in flats that have run for years on hard water, older regular boilers in the southern suburbs, and the odd floor-standing boiler in a basement. Long flue runs and shared gas meters in basements are common, which affects how quickly we can trace a fault.

Breakdowns we see most often across the city
Hot water that runs hot then cold
In this hard water area, the plate heat exchanger in a combi slowly fills with scale. The hot water starts surging, then the boiler locks out on overheat. We confirm the cause with a few simple tests, then descale or replace the heat exchanger and talk to you about scale protection.
Blocked terminals in lightwells
Basement flats often flue into a small lightwell or area at the front. Leaves, litter and nesting birds can build up around the terminal and starve the boiler of air, which shows up as repeated ignition faults. We clear and check the terminal, and add a guard if the position allows it.
Leaks under old floorboards
Georgian and Victorian houses hide decades of pipework under their floors, from old steel to joined copper. A slow leak shows up as pressure that keeps dropping. We trace it with as little disturbance as we can, lifting only the boards we need to, and repair the joint or section that has failed.

What helps when your heating stops in a flat or townhouse
Before you call, check the pressure gauge, the programmer, the boiler's fuse spur and whether other gas appliances are working. Note any fault code on the display. If you have a prepayment meter, check there is credit on it, as that catches people out more often than you would think.
In many converted buildings the gas meter and stopcock are in a shared basement or a locked cupboard. Find out where yours are now, and keep any key somewhere you can reach in the dark. It makes a real difference if we need to isolate the gas or water quickly.
Let us know about parking and stairs when you book, as some flats are four floors up with no lift and no space outside. If you think you can smell gas, call the gas emergency line first, and then read our page on gas leak repair for what happens next.
Why choose Wisp for boiler repair in Bath
Frozen condensate pipes
Exposed plastic condensate pipes on north-facing walls up Lansdown freeze in hard frosts. We thaw them, then reroute or insulate so it does not happen again.

Boiler installation BathBoiler Repair Bath FAQs
My boiler pressure keeps dropping. Is that a leak?
Often, yes. It can be a weeping radiator valve, a failed pressure relief valve or a leak under the floor of an older terrace. A heating engineer can pressure test the system, trace the loss and fix the cause, rather than you topping it up every few days.
Can you repair an old floor-standing boiler in a period house?
Usually. We work on older floor-standing and back boilers as long as parts are still available and the appliance passes its safety tests. If it fails one, we will explain exactly why, make it safe, and talk through replacement options so you can decide without being rushed.
I smell gas. Should I call you?
Call the National Gas Emergency Service on 0800 111 999 first. Open windows, do not use light switches or naked flames, and turn off the gas at the meter if you can do it safely. Once the emergency service has made the supply safe, we can trace and repair the fault.
The gas meter for my flat is in a shared basement I cannot get into. Is that a problem?
It can slow a repair down, because we sometimes need to isolate the gas or check the meter pressure. Ask your managing agent or freeholder for access, or for a key, before anything goes wrong. If you are a tenant, your landlord should be able to arrange it. We will tell you when booking if we need meter access.
Is it worth repairing a combi that keeps scaling up?
Often, yes, if the boiler is otherwise in good order. Replacing or descaling the heat exchanger and fitting a scale reducer can give it years more life. If the boiler is old and other parts are starting to go, we will price the repair and a replacement side by side so you can compare.
