Boiler Problems We Repair

No heating or hot water

Losing access to heat or hot water is one of the most common reasons homeowners call for repairs. This issue can be caused by faulty sensors, broken valves, damaged internal components, incorrect thermostat settings or problems with water pressure. We check each part of the boiler and heating circuit to pinpoint the cause and restore consistent performance.

Boiler pressure issues

Boilers rely on stable pressure levels to work correctly. If the pressure becomes too low, the system may shut down completely. If the pressure becomes too high, it can cause leaks or damage internal parts. We test for leaks, inspect safety valves, check expansion vessels and ensure the pressure is restored to a safe level for long term operation.

Strange noises from the boiler

Boilers should operate quietly, so any unusual noises such as banging, rumbling, whistling or tapping can be a sign of trouble. These sounds often indicate trapped air, a worn pump, limescale buildup or loose internal fittings. Left unresolved, these issues can place further strain on the boiler, so early repair helps prevent major breakdowns.

Boiler not firing up

If your boiler refuses to ignite, the fault may be linked to ignition failure, blocked flues, faulty flame sensors, damaged wiring or an issue with the gas supply. Our engineers carry out thorough safety checks and inspect all ignition components to ensure a safe and complete repair.

Leaks or dripping from the boiler

A leaking boiler can cause significant water damage if it is not repaired quickly. Leaks often develop due to worn seals, damaged heat exchangers, loose connections or internal corrosion. We locate the exact source of the leak and complete a secure repair that prevents further deterioration.

Faulty thermostats, timers and heating controls

If your heating is turning on and off at unpredictable times or your temperature controls no longer respond, the issue may be linked to outdated or malfunctioning thermostats. We test wiring, sensors and control units to restore accurate and efficient heating regulation.

Our Repair Process

Step 1: Initial assessment

We begin by discussing the symptoms you have noticed, reviewing your boiler’s behaviour and examining the layout of your heating system. This helps us build a clear picture of the fault before we begin testing.

Step 2: Fault finding

Using advanced diagnostic tools, we test key components to identify the exact cause of the breakdown. Once the fault is confirmed, we explain the problem clearly and outline your repair options.

Step 3: Repair or replacement of parts

If the repair can be completed on the first visit, we will carry out the work immediately. If new parts are required, we will provide a clear quote and arrange a follow up visit. We only use high quality, manufacturer approved parts to support long term reliability.

Step 4: System testing

After the repair is completed, we run the boiler through extensive performance checks and safety tests. This ensures the heating system is operating correctly and safely before we leave your property.

Step 5: Aftercare, advice and optional servicing

Once the repair is finished, we provide guidance on how to avoid similar issues in future. We also offer annual servicing, system inspections and maintenance plans to keep your boiler performing efficiently throughout the year.
