Fast, reliable boiler breakdown repairs from Gas Safe registered engineers across Northampton.
A broken boiler is never convenient, especially in winter. We diagnose and repair boiler faults across Northampton quickly, carrying common parts so many repairs are completed on the first visit. Every repair is carried out by a Gas Safe registered engineer.
We identify the fault properly rather than guessing, and explain what's wrong and what the repair involves before any work starts.
No hot water, no heating, leaks, pressure loss, error codes, pilot and ignition faults, noisy boilers and frozen condensate pipes.
We carry common spares so many repairs are done same-visit; anything else is ordered quickly with a clear quote.
If a boiler is beyond economical repair we tell you straight, with no pressure, so you can decide.

Whatever your boiler is doing, we'll find the cause before quoting. Here are the faults we see most often:
If your boiler pressure keeps dropping below 1 bar, it usually points to a leak somewhere in the system, a failing pressure relief valve, or a waterlogged expansion vessel. We trace the actual cause rather than just re-pressurising and sending you on your way — a re-pressurise that doesn't hold is a symptom, not a fix.
If your radiators stay cold, common causes include a faulty diverter valve, a seized pump, a failed thermostat, or an airlock. We work through the system methodically to find which it is, then quote before carrying out the repair.
No hot water but heating still works (or vice versa) usually points to a diverter valve fault on a combi boiler. We diagnose and, where possible, repair on the first visit with parts carried on the van.
If the boiler won't ignite, it can be an ignition or flame-sensing fault, a gas supply issue, low pressure, or a blocked condensate pipe. We identify the specific cause for your make and model.
Water around or under the boiler should never be ignored. Leaks can come from internal seals, the pump, the pressure relief valve or corroded pipework. We find the source and advise on the safest repair.
Banging or kettling usually means limescale or sludge in the heat exchanger; whistling can be trapped air; gurgling often means air or low pressure. Each has a different fix, and we identify which applies.
Modern boilers display fault codes that mean different things across brands (Worcester Bosch, Vaillant, Ideal and others). We read the code, interpret it correctly for your specific boiler, and explain what the repair involves.
Cold at the bottom points to sludge build-up; cold at the top means trapped air. Depending on the cause we'll bleed, balance, or recommend a power flush — see our central heating page for flushing.
A faulty or poorly-sited thermostat can cause a boiler to short-cycle, overheat rooms, or fail to fire at all. We test the thermostat and controls as part of diagnosis and can upgrade to smart controls if wanted.
We don't guess. Every repair starts with a proper diagnosis: we run the boiler, read any fault codes, check pressure, gas supply and key components, and identify the root cause. Our first hour includes full diagnosis at £105 inc VAT, and we always quote any parts and further work before we carry it out — so you're never surprised by the bill.
Sometimes a repair is the sensible choice; sometimes an ageing or repeatedly-failing boiler is costing you more than it's worth. We give you an honest assessment based on the age, condition and running cost of your boiler — with no pressure. If a new boiler genuinely is the better option, we'll tell you, and you can read about that on our Northampton boiler installation page. If not, we'll fix what you've got.
