As autumn begins and colder weather approaches, many homeowners are switching their heating back on. This is the most common time of year for problems to show up. That’s why boiler servicing and repairs in East London are essential to keep your home safe, warm and efficient. At DL Gas & Maintenance, our Gas Safe engineers specialise in seasonal boiler servicing, emergency breakdown repairs and new installations across East London, South East London and Dartford.

Why Boiler Servicing and Repairs in East London Are Essential in Autumn

There are a few reasons why autumn tends to be the busiest season for boiler repairs:

Dormant Systems Restarting: After months of little or no use, parts like pumps, valves, and fans can seize up when the boiler is switched on again.

• Pressure Problems: Cold weather causes pipes and joints to contract, sometimes leading to leaks and drops in boiler pressure.

• Airlocks in the System: Turning the heating back on often reveals air trapped in radiators or pipes, stopping hot water from circulating properly.

• Frozen Condensate Pipes: Even in early autumn, overnight temperatures can dip low enough to freeze external condensate pipes, leading to boiler shutdowns.

• Faulty Thermostats: Thermostats that haven’t been used since spring may stop communicating with the boiler, leaving the heating unresponsive.

Common Boiler Repairs in East London During Autumn

Our engineers are regularly called out to repair these common issues:

• No heating or hot water – often linked to broken diverter valves or airlocks.

• Strange noises – banging, gurgling, or whistling usually indicate limescale build-up (kettling) or air in the system.

• Low pressure – caused by leaks, faulty pressure relief valves, or bleeding radiators.

• Pilot light keeps going out – often related to thermocouple faults or gas supply issues.

• Radiators not heating evenly – sludge build-up in the system may require a power flush.

If you notice any of these warning signs, it’s best to call a Gas Safe engineer before the issue worsens.

Benefits of Autumn Boiler Servicing

Booking a boiler service now gives you peace of mind before winter. During a service, our engineers:

• Check all major components for wear and tear

• Clean internal parts to improve efficiency

• Test gas pressure and emissions for safety

• Inspect for leaks and potential carbon monoxide risks

• Make sure your heating is ready for the colder months

A well-maintained boiler not only runs more reliably but also helps keep energy bills down – a big advantage with rising energy costs.
