Additional Recommended Service For Longevity of Your Heating System
As heating specialists, we highly recommend Powerflushing, this is a deep-clean solution for older heating systems that removes sludge and improves performance. This is especially beneficial after boiler servicing or when upgrading to a modern, high-efficiency boiler. Powerflushing can extend the lifespan of your central heating, lower bills, and prevent cold spots in radiators.

Boiler Servicing & Maintenance Across London: Overcoming Regional Challenges
At 0800 Homefix, we provide expert boiler servicing across London, tailored to the unique challenges of each area. From hard water issues in North and West London to older homes in East London, our Gas Safe registered engineers ensure your heating system runs efficiently year-round.
North London
North London’s varied housing stock includes period and modern homes. Radiators failing to heat, boiler breakdowns, and sludge accumulation are common & hard water increase the occurrence of these issues.
Our Approach:
We provide thorough diagnostics and tailored solutions, including descaling and system flushing. In hard water areas we also suggest considering a powerflush of your radiators with your boiler service as a preventative measure to keep the whole system running smoothly. Please request this service if this is of interest when making your booking
East London
East London features many older properties, which can mean inefficient heating systems and increased wear on boilers and heating systems. The area also experiences high demand for boiler repair services, especially in winter months. Water hardness is moderate, so limescale can build up over time. Our qualified engineers will advise you if a powerflush is necessary.
Our Approach:
We maintain a large, fully trained team of Gas Safe registered heating engineers. Our team can service, descale, and service boilers, providing same-day call-outs and emergency boiler repairs when needed.
South London
South London features a mix of older Victorian terraces and newer developments, which can lead to differing boiler issues. Ageing systems in period properties often suffer from inefficiency and wear, while modern homes still face risks of breakdowns during peak winter demand. The area also has hard water, which makes limescale buildup a common problem over time increasing the demand for boiler repairs.
Our Approach:
We have a team of Gas Safe registered heating engineers covering South London, providing expert boiler servicing and preventative heating system maintenance. Our engineers carry out descaling and system flushing as needed, also in hard water areas, we often recommend a powerflush alongside the boiler service to keep heating systems running at their best. If you would like this service added please discuss with one of our agents when making your booking.
West London
West London has many high-value properties with complex heating systems. Common issues include noisy boilers, water leaks, and gas odors. Hard water is a major factor, causing limescale build-up that can reduce efficiency and lifespan.
Our Approach:
0800 Homefix engineers have extensive experience in installing water softeners, descaling, and performing comprehensive boiler servicing. In areas with hard water such as West London, we highly recommend a powerflush to remove sludge and limescale, protecting your system and improving efficiency. If this is of interest and you would like it included during your boiler service, please let us know at time of booking.
Central London
Central London faces significant challenges from very hard water due to the local chalk and limestone geology. This causes limescale buildup inside boilers and pipes, reducing efficiency and increasing boiler breakdown risks.
Our Approach:
Our Gas Safe registered heating engineers are experts in servicing boilers in hard water areas. We perform thorough limescale inspections during an annual boiler service, & strongly recommend a powerflush in this area, in addition we can also install water softeners or scale inhibitors to protect your central heating system and improve energy efficiency. Please let us know at time of booking if you would like this service included.
