What happens during boiler servicing in Emsworth?
During boiler servicing in Emsworth we work through a set of checks on the boiler, the flue and the controls:
- Visual check: we look at the boiler, flue and pipework for signs of leaks, corrosion or damage.
- Open the boiler: we remove the casing to inspect the burner, heat exchanger, fan and seals.
- Clean: we clean parts as needed, including the condensate trap on condensing boilers.
- Test: we check the gas pressure and use a flue gas analyser to confirm the boiler is burning safely.
- Check controls: we test the safety devices, system pressure and controls.
- Report: we record the results and tell you about anything that needs repairing.
How often should a boiler be serviced?
A gas boiler should be serviced once a year. Most manufacturers ask for an annual service to keep the warranty valid. Landlords must also have gas appliances in rented homes safety checked every 12 months under the Gas Safety (Installation and Use) Regulations 1998.
| Visit | What it is for | When you need it |
|---|---|---|
| Boiler service | Cleans and tests the boiler so it runs safely and efficiently. | Every year, and to keep most warranties valid. |
| Gas safety check | A safety-only check of gas appliances, pipework and flues. | Every 12 months by law in rented homes. |
| Boiler repair | Finds and fixes a specific fault. | When the boiler stops working or shows a fault code. |
What are the signs my boiler needs a repair?
Your boiler probably needs a repair if it stops heating, loses pressure or shows a fault code. Look out for:
- No heating or hot water, or hot water that runs cold.
- The pressure gauge keeps dropping below about 1 bar.
- Banging, gurgling or kettling noises from the boiler or pipes.
- A fault code or a flashing light on the display.
- Water leaking from the boiler or the pipes underneath it.
A yellow or orange flame, soot or staining can mean the boiler is not burning safely. Turn it off and do not use it. If you smell gas, call the National Gas Emergency Service on 0800 111 999.
Can you repair my boiler?
Yes. We diagnose boiler faults and replace parts such as fans, pumps, valves, sensors and seals. The photo on this page shows a worn fan impeller we removed during a repair. If a boiler is old and repairs would cost more than they are worth, we explain the options honestly so you can decide.
