Boiler repairs & servicing

Boiler repairs and servicing in Keynsham

A boiler that's losing pressure, banging or not heating properly doesn't have to mean a replacement. We diagnose what's wrong, fix it and get you back to hot water and heating. Annual servicing also catches problems early and keeps your warranty valid.

Why Keynsham boilers need regular care

Hard water and older systems wear faster here

Keynsham sits in an area with hard water, and that's tough on boilers. Limescale builds up in the heat exchanger, the water pump works harder, and the boiler has to keep fighting against it. Most homes here were built in the 1970s and 1980s, and a boiler that's been running for eight to ten years is starting to earn its repair bills.

Many properties also still have system boilers with a cylinder in the airing cupboard, and older radiator systems that have picked up sludge over the years. A tired boiler paired with a clogged system means it's working twice as hard to deliver less heat, and faults start to pile up.

A service every year catches corrosion and wear before they become a breakdown call. And if the boiler is heading towards the end of its life, we'll tell you straight: a new one might make more sense than pouring money into repairs.

Signs your boiler needs attention

  • It's making noise: banging, whistling or rumbling in the pipework
  • Radiators are cold at the bottom or take a long time to warm up
  • The boiler is losing pressure and you're topping it up regularly
  • It's not reaching the temperature you set on the control
  • It shuts down unexpectedly or struggles to restart
  • It hasn't been serviced in more than a year

Two kinds of Keynsham home, two different jobs

Detached and semi-detached houses

Boilers in kitchens or garages

Most Keynsham homes have the boiler tucked away in a kitchen corner or garage, often paired with a cylinder upstairs. A service is straightforward access, though we check the flue and the gas pipe for signs of age. If radiators are sluggish, sludge in the system is often the culprit, and a powerflush can be the cheaper fix before replacing a boiler.

1970s and 1980s builds across the town

System boilers with sludge problems

Houses built in that era often have larger radiator systems that have accumulated sludge and debris. The boiler works overtime trying to push heat through a clogged system. We diagnose whether it's a quick fix (a new pump, a powerflush) or whether the boiler itself is failing, so you can plan ahead.

What happens during a service or repair

Step by step: from inspection to handover

A service takes around an hour. A repair depends on what's wrong, but we'll give you a clear picture as soon as we know.

  1. We inspect and test

    We check the burner, electrodes, heat exchanger and flue. We test for gas tightness, measure the combustion efficiency and look for corrosion or wear.

  2. We clean the internals

    Scale and debris come out, the boiler is flushed, and we replace the filter if it's clogged. A clean boiler runs more efficiently and uses less gas.

  3. We explain what we find

    If there's wear or a small fault, we tell you what it is, show you and explain whether to fix it now, monitor it or plan for a replacement.

  4. We fix what needs fixing

    Common repairs: replacing a valve, reseating the burner, fixing a faulty pump or control. We use genuine parts and give you a written guarantee.

  5. Final check and paperwork

    We commission the boiler, confirm it's running safely and efficiently, and update the service record. You get a certificate and a copy of what we've done.

What affects the repair bill

Three things that change the cost of fixing your boiler

We can't give you a price over the phone, because we don't know what's wrong. Here's what moves the figure.

What part needs replacing

A thermostat or valve is a smaller job and a smaller bill. A pump, circuit board or heat exchanger costs more. We tell you the price of the part before we order it.

How long the job takes

A simple clean and reset might take an hour. If the boiler needs to be taken apart, the part ordered and fitted, it's a longer job. We agree the time before starting and update you if it changes.

Whether the system needs attention too

If a powerflush is needed to clear sludge from the radiators, or radiator valves are stuck and need replacing, that's extra time and cost. We spot it at the inspection and discuss it with you first.

No callout charge, and we give you a price in writing before we start the work. If something unexpected comes up, we tell you then.

Questions we get asked

Boiler repair and service questions, answered

How often should I have my boiler serviced?

Once a year is standard and keeps your warranty valid. If your boiler is over ten years old or you've had a repair, an annual check is a good idea. We can set you up on a reminder if you like.

Can you service any boiler?

Yes, we service most gas boilers, regardless of the brand. Oil boilers are outside our scope. Tell us the make and model when you book and we'll confirm we can handle it.

What if the repair is going to cost more than a new boiler?

We'll be honest about it at the inspection. If you're looking at a large bill on a boiler that's already ten years old, a replacement often makes more sense in the long run. We can survey you for a new one and give you both prices.

Is a powerflush worth doing?

If your radiators are cold at the bottom or the boiler is struggling, sludge in the system is often the reason. A powerflush clears it, costs less than a new boiler, and makes the heating work as it should. We'll recommend one if we spot the problem.

Do you charge for the callout?

No callout charge. You only pay if you go ahead with the repair. We give you a written price before we start work.

What's the guarantee on repairs?

We give a 5-year guarantee on any parts we fit and the labour. If something fails within that time and it's because of our work, we'll come back and fix it at no charge.
