When your boiler stops working, you probably don’t want a technical lesson, you just want to know what’s wrong, whether it can be fixed and what it’s likely to cost. That’s how we approach boiler repairs. We’ll diagnose the problem, explain what we’ve found and advise you on the most cost efficient way forward. If your boiler can be repaired, we’ll aim to get it back up and running. If we think you’re better off putting the money towards a replacement, we’ll tell you that too. We can help with a wide range of boiler and central heating faults.
Sometime's its simple, but sometimes you need a professional
Sometimes the problem is something simple. Before calling an engineer, there are a few safe checks you can make:
make sure the display is on and it hasn't been switched off accidentally.
low system pressure can prevent some boilers from operating.
make sure it's switched on and calling for heat.
check timers and programmers haven't been changed or reset.
if you have another gas appliance, this can help establish whether the issue is isolated to the boiler.
Still not working? Don’t remove the boiler casing or attempt a repair yourself. Give our team a call and we’ll take it from there.
Not every faulty boiler needs replacing.
Even if your boiler is over 10 years old, a repair may still make sense depending on the fault, the condition of the boiler and whether replacement parts are readily available.
We’ll give you a straightforward assessment. If a sensible repair can give your boiler more life, we’ll tell you. Equally, if repair costs are starting to mount up and replacing the boiler would make better financial sense, we’ll explain your options.
If replacement is the better route, you can also speak to us about a new Worcester Bosch boiler installation in Aylesbury.

Common signs include no heating or hot water, unusual noises, regularly losing pressure, leaking water, intermittent heating or a fault code appearing on the boiler display. If something doesn't seem right, get in touch and we can help diagnose the problem.
Yes. We provide boiler repairs across Aylesbury and the surrounding areas, helping homeowners with boiler faults, breakdowns and central heating problems.
Our engineers can diagnose and repair faults on a wide range of boiler makes and models. If you're unsure whether we can help with your particular boiler, just give us a call.
Boiler pressure can drop for several reasons, including a leak somewhere in the heating system or a problem with a component inside the boiler. If you're regularly having to repressurise your system, it's worth having the cause investigated.
Age alone doesn't mean a boiler needs replacing. If the fault is relatively inexpensive to fix, parts are readily available and the boiler has otherwise been reliable, repairing it can still make good sense. We'll advise you if we believe replacement would be the more economical option.
It depends on the boiler's age, condition, repair cost and history of breakdowns. A single straightforward fault may be well worth repairing, whereas repeated expensive repairs can make investing in a new boiler the better long-term decision.
Potentially, yes. Once your boiler and heating system are working correctly, speak to us about our Boiler Care Plans. We offer different levels of ongoing maintenance and cover, including an annual boiler service.
Make a note of the fault code displayed and check your manufacturer's instructions for any basic checks you can safely carry out. If the fault remains, contact a Gas Safe registered engineer rather than attempting to open or repair the boiler yourself.
