Boiler repair in Biggleswade, with same day response on no heating and no hot water. Our engineers carry common parts for the main brands, so most faults are diagnosed and fixed on the first visit.
Pressure dropping, a boiler locking out on a fault code, no hot water but heating still on, kettling noises, or a pump that has seized after summer. Most of these come down to a handful of parts. Diagnosis is the important bit, because swapping parts on a guess gets expensive.
More Information
We will tell you honestly which makes sense. If a boiler is under ten years old and parts are available, repair is nearly always the better option. If the same boiler keeps failing, parts are obsolete or the heat exchanger has gone, we will explain why replacement is the sensible route.
The van carries pumps, fans, valves, thermistors and pressure sensors for the brands we see most. When a part has to be ordered, we tell you when it will land and get you working again as fast as we can, leaving temporary hot water on where it is possible.
Repairs are treated as urgent, especially in cold weather and for households with young children or older residents. We work on all the main boiler brands and have done for 20 years. Every repair is tested afterwards and the controls checked, rather than just clearing the fault code.

STILL NOT SURE?
Water is escaping somewhere or the expansion vessel has failed. Check radiator valves and visible pipework for damp first. If nothing shows, it is often a leak under a floor or a failed vessel or pressure relief valve. We test the vessel and trace the leak rather than just topping it up.
Fault codes point to a general area rather than an exact part. The same code can mean a blocked condensate pipe, a failed sensor or a flow problem. Tell us the code and the make when you call, because it helps us bring the right parts to the first visit.
Yes. We take calls 24 hours a day, seven days a week, including weekends and bank holidays. No heating or no hot water in cold weather is treated as an emergency. Ring and we will tell you when we can be there and what the visit will cost.
