what we do
Common Boiler Faults We Fix
We see a wide range of boiler problems across the properties we attend in Gloucestershire. Some of the most common include:
- No heating or hot water: The boiler fires but does not produce heat, or fails to ignite at all. This can be caused by a faulty diverter valve, a broken motorised valve, a failed pump, or an ignition issue.
- Boiler losing pressure: The pressure gauge drops below 1 bar, sometimes repeatedly after topping up. This usually points to a leak in the system, a failing pressure relief valve, or a problem with the expansion vessel.
- Leaking boiler: Water around the base of the boiler or visible dripping from internal components. Causes range from a failed seal or pump to a cracked heat exchanger.
- Strange noises: Banging, kettling, gurgling or whistling sounds. Banging can indicate trapped air or a failing pump. Kettling (a noise like a boiling kettle) is often caused by limescale buildup on the heat exchanger.
- Pilot light or ignition failure: The boiler will not light or keeps cutting out. This may be a faulty thermocouple, a blocked burner, or a gas valve issue.
- Error codes and lockouts: Modern boilers display fault codes when they detect a problem. Our engineers are familiar with the code systems used by all major manufacturers and can quickly identify what the boiler is reporting.
- Frozen condensate pipe: In cold weather, the condensate pipe that runs outside can freeze, causing the boiler to shut down. This is one of the most common winter callouts and is usually a quick fix.
- Radiators not heating properly: Cold spots, radiators that heat unevenly, or radiators that do not warm up at all. This can be caused by trapped air, sludge buildup, or a balancing issue within the system.
OUR PROCESS
How We Handle a Boiler Repair
- Get in touch: Call us on 01452 452002 or use the contact form. Let us know your boiler's make and model if you can, along with any error codes or symptoms. This helps our engineer prepare before arriving.
- Diagnosis: Our engineer will inspect the boiler, run the necessary tests, and identify the fault. We will explain what has gone wrong in plain language.
- Quote and repair: You receive a clear price for the repair before any work starts. If we have the part on the van, we can often fix it there and then. If a part needs to be ordered, we will let you know the expected lead time and arrange a return visit.
- Testing: Once the repair is complete, we test the full system to make sure everything is running as it should before we leave.

When to Repair and When to Replace?
We will always give you an honest assessment. There are times when a repair is the right call, and times when putting more money into an old boiler is not worthwhile. As a general guide:
- If the repair cost is approaching half the cost of a new boiler, replacement is usually the better investment.
- If the boiler is over 12 to 15 years old and parts are becoming difficult to source, ongoing reliability will be a concern even after the repair.
- If the same fault keeps recurring, it may point to a deeper issue with the system that a repair alone will not solve.
If we think replacement is the better option, we will say so and explain why. We can then arrange a free home survey through our installation team to quote for a new boiler.
FAQs
Frequently Asked Questions
How quickly can you attend a boiler repair?
We aim to arrange a visit as soon as possible, and we prioritise jobs where there is no heating or hot water. Availability depends on demand, but in most cases we can attend within one to two working days. If you have a genuine emergency, let us know when you call and we will do our best to get to you sooner.
How much does a boiler repair cost?
It depends on the fault and which parts are needed. Minor repairs such as replacing a pressure relief valve or resetting an ignition fault are at the lower end. More involved work like replacing a heat exchanger or a gas valve costs more. We always provide a clear price before starting the repair so there are no surprises.
My boiler has an error code - what should I do?
Make a note of the code displayed on the boiler's screen and contact us. Error codes tell our engineers what the boiler has detected, which speeds up the diagnosis. If you can, include the boiler make and model when you get in touch.
Is it worth repairing an old boiler?
It depends on the boiler's age, the cost of the repair, and how often it has been breaking down. If the boiler is under 10 years old and the repair is a one-off, fixing it usually makes sense. If it is over 12 to 15 years old and needing regular repairs, the money may be better spent on a new installation.
My boiler has lost pressure - is this an emergency?
Low pressure is not usually dangerous, but the boiler may stop working until the pressure is restored. You can try topping up the pressure yourself using the filling loop (usually a small valve or tap beneath the boiler). If the pressure drops again within a few days, there is likely a leak in the system and you should book a repair.
Do you carry parts for same-day repairs?
Our engineers carry a stock of the most common boiler parts on the van, including valves, pumps, ignition components and sensors. This means many faults can be fixed on the same visit. If a specific part needs to be ordered, we will arrange a return visit as quickly as possible.
