Central heating engineers in London
domestic and commercial
London Property Services provides Gas Safe registered central heating engineers across London for homes and businesses. Our specialists work on the whole system, not just the boiler, from cold radiators, faulty controls and worn pumps to power flushing, HIU servicing and full system upgrades.
When your heating isn’t performing, the cause isn’t always the boiler. Radiators that don’t warm up, uneven heat between rooms, a system that’s slow to get going, or one that loses heat quickly can all point to problems in the system that need investigating.
Our engineers look at the whole system to see how it’s performing, diagnose the real cause and give you straight-up, honest advice before repairs begin.

Central heating repairs in London
A central heating fault is often somewhere in the wider system rather than the boiler itself. Cold radiators, poor circulation, trapped air, worn pumps, faulty valves, ageing controls or sludge build-up can all stop your heating working as it should.
Our London central heating engineers diagnose and repair faults across the whole system, including radiators, pipework, pumps, programmers, thermostats, control valves and cylinders. This is especially useful if your heating is working in some rooms but not others, making unusual noises or takes too long to warm up.
If the fault is with the boiler itself, our emergency boiler repairs team handles breakdowns, whilst our gas engineers in London conduct boiler servicing and general gas work when required.


Power flushing
Over time, sludge and debris build up inside radiators and pipework, restricting the flow of hot water around the system. If this is happening with your heating, you might notice the radiators stay cold at the bottom, are slow to warm up or need frequent bleeding. You might also notice that your running costs start to increase as the system loses some of its efficiency.
A power flush in London performed by our central heating engineers will clean the system, removing sludge, allowing water to move freely, and returning the system to its efficient best. Power flushing can also help extend the lifespan of your system and reduce the risk of future breakdowns. Our engineers will advise whether this is the right solution before carrying out any work.
Radiators, controls and pumps
Much of what keeps a home comfortable sits in the parts of the system around the boiler, and these are the components our team replaces, repairs or upgrades:
- Radiator removal and replacement when required
- Thermostats, programmers and heat controls
- Circulation pumps
- Motorised and thermostatic radiator valves
- Hot water cylinders, tanks and immersions
Upgrading tired controls or an inefficient radiator can make a home noticeably more comfortable and cheaper to run. Before we repair or replace anything, we’ll discuss options with you, so you can feel confident in your decision.


HIU service and repair
We are specialists in servicing, repairing and maintaining Heat Interface Units (HIUs). These units provide heating and hot water to individual flats connected to a communal or district heating system.
Repairs: We diagnose the fault with your HIU and, where it can’t be resolved on the first visit, provide a feedback report detailing the work that is required. Speak to us today about HIU repair in London.
Servicing and maintenance: Many HIUs need an annual service to keep the warranty valid. We carry out heat interface unit servicing within a call-out and provide you with a follow-up report highlighting any faults, if any, along with an estimate for any work that may be needed.
For managing agents, developers and landlords responsible for blocks with communal heating, we are the perfect fit for rapid assessment, repairs and maintenance.
Central heating installation and upgrades
Some older heating systems can often be improved without the need to replace everything. Updating the controls, replacing inefficient radiators or upgrading worn components can all make a property more comfortable and cheaper to heat.
We install and upgrade central heating systems for homes and businesses across London, and we’re not tied to one manufacturer, so our recommendations are based on your property, your system and your budget.

Our Happy Clients

How much does a central heating engineer cost in London?
We remain fully transparent with our pricing. Every central heating job is different, so our quotes are prepared based on the scope of the job. A minor repair such as a faulty valve is priced very differently to a power flush or a full system installation.
For a power flush, pricing is determined by the size of the system and the number of radiators in your property. With London Property Services, the price we quote is the price you pay.

We don’t just maintain, repair or replace residential central heating systems. We work on commercial central heating repairs in London too. Whether it’s commercial premises, a managed block or a communal system, our team can be dispatched to make it safe, make it functional and make it efficient.
