Frequently Asked Questions

Everything you need to know about our boiler repair service.

Do you handle both urgent and non-urgent boiler repairs?
Yes. Boiler Repair covers everything from urgent breakdowns (no heating, no hot water) to non-urgent faults like a fault code or an intermittent issue — it's one service, with urgency affecting how quickly we prioritise the visit rather than which service you book.
What counts as a boiler emergency?
No heating, no hot water, a boiler that will not fire up, a leak from the boiler, or a winter breakdown affecting vulnerable occupants are all common reasons to request urgent help.
What is included in a boiler repair visit?
The visit includes engineer dispatch (rapid, for urgent cases), diagnosis, a temporary fix where possible, and upfront pricing for any extra work needed.
Do you offer same-day boiler repair?
Often yes. Same-day response is available when schedules and location allow, and is prioritised for urgent cases.
What should I do before the engineer arrives?
Check whether the thermostat is calling for heat, whether the pressure is low, whether the condensate pipe may be frozen in cold weather, and whether there is a fault code on the display. If you smell gas, do not keep testing the boiler.
Can you always fix the boiler on the first visit?
Not always. Some faults need replacement parts or further testing. Where possible we aim for a first-visit fix or a safe temporary solution.
Do you repair boilers with no hot water but heating still works?
Yes. That is a common boiler fault pattern and can be caused by several issues, including diverter valve or control problems in some systems.
Do you repair boilers with no heating but hot water still works?
Yes. This can happen because of settings, thermostat issues, air in radiators, valve problems, or system faults depending on the boiler type.
Can you help if the boiler keeps switching itself off?
Yes. Boilers can switch off due to pressure issues, thermostat faults, frozen condensate pipes, overheating, or internal component faults.
Can you diagnose fault codes on the display?
Yes. Fault codes are useful clues and help narrow down the likely issue, although final diagnosis still depends on inspection and testing.
Can you help in cold weather when the condensate pipe is frozen?
Yes. A frozen condensate pipe is a common winter issue on condensing boilers and can stop the boiler from running.
What if my boiler is leaking water?
A leak should be treated seriously. Water can damage internal components and surrounding areas, and the underlying cause can range from pressure problems to failing seals or corroded parts.
What if I smell gas near the boiler?
Treat that as an emergency. Turn off the gas supply if it is safe to do so, open windows, avoid flames or electrical switches, leave the area, and contact the National Gas Emergency Service and a Gas Safe professional.
Do you repair old boilers?
We assess older boilers where possible, but if parts are obsolete or the repair is poor value compared with replacement, we will explain your options.
