Central heating keeps London homes warm, safe, and comfortable. Many homes across London still use old or broken heating systems. A new central heating installation can improve comfort, save money, and increase property value.
In this guide, we explain how central heating installation works in London properties, step by step. This guide is easy to read and helpful for homeowners, landlords, and businesses.
What Is Central Heating?
Central heating is a system that heats your whole home from one main source. The heat usually comes from a gas boiler, but it can also use electricity or renewable energy.
The system sends hot water to:
Radiators
Underfloor heating
Hot water taps
Most London homes use gas central heating because gas is affordable and reliable.
Why Central Heating Installation Is Important in London
London properties are very different. Some homes are old Victorian houses. Others are new flats or apartments. A proper heating installation is important because:
London winters can be cold
Old systems waste energy
New systems reduce heating bills
Landlords must meet legal heating standards
Homes with good heating sell faster
A professional central heating engineer in London ensures the system is safe and efficient.

Step 4: Pipework Installation or Upgrade
Pipes carry hot water from the boiler to radiators.
