A selection of some of the brands we repair

After our boiler suddenly failed mid-cold-spell, Andrew arranged a same-day visit and fixed the problem far quicker than expected. Honest pricing, helpful maintenance tips, and genuinely outstanding service. We'll definitely be calling Andrew again.

Very responsive plumber — contacted on a Saturday afternoon about the boiler not working. He came within 3 hours and sorted the issue. Really saved the day. Highly recommend 👌

Andrew came at very short notice when our boiler stopped working. He found the programmer/timer was at fault and replaced it. Explains everything thoroughly, very tidy, and definitely recommend to everyone. Thanks Andrew.

Repairs That Fix the Cause, Not the Symptom

Repeat call-outs for the same fault waste time and money. We trace the problem to its source before recommending anything. Our repair service includes:

Proper fault diagnosis – error codes, pressures and components checked in order
Quote before work – you see the cost and the options before we start
Parts matched to your boiler – manufacturer-approved where available
Tested before we leave – heating and hot water both confirmed working
Plain explanations – what failed, why, and how to avoid a repeat

How a Boiler Repair Works

Step 1 - Describe the problem

Call 07501 619 738 and tell us what the boiler is doing, any error code and the make and model.

Step 2 - Visit booked

We arrange a visit with a Gas Safe engineer who carries common parts for the most frequent faults.

Step 3 - Fault traced

The engineer tests the boiler and system to find the real cause rather than guessing.

Step 4 - Quote and options

You get a clear quote. Where it makes sense, we also tell you if replacement would be better value than repair.

Step 5 - Repair and handover

We fix the fault, test the system and explain what was done.

Faults We Diagnose and Repair

Our engineers see the same problems again and again across Hemel Hempstead homes, including:

Boiler pressure dropping or too high
Radiators cold at the bottom or the top
Banging, kettling or whistling noises
Error codes and lock-outs
Boiler not firing up or igniting
Leaks from the boiler or connected pipework
Faulty diverter valve, pump or circuit board
Blocked or frozen condensate pipe
Thermostat, timer or programmer faults
Hot water that never gets properly hot

When Repair Makes Sense, and When It Does Not

A repair is usually worth it when the boiler is fairly young and the fault is limited to one part. If the boiler is old, parts are scarce or repairs keep repeating, we will tell you so.

In that case we show you the replacement route so you can compare like for like. See our Boiler Replacement page.
