Central Heating Installation South London
Full central heating installation for South London's Victorian terraces, ex-council flats moving off communal heating, and larger family homes — boiler, radiators, pipework and controls, fitted and certified in one job. From £4,000.
How Much Does Central Heating Installation Cost in South London?
Full central heating installation in South London starts from £4,000 for a smaller flat, rising to £6,500–£8,500+ for a typical 3 to 4 bedroom Victorian or Edwardian house. This includes the boiler, radiators, pipework, controls, and your Gas Safe certificate. Converting an ex-council flat from communal to individual heating is priced separately after an assessment, since building permissions and pipework routing vary by block.

South London Property Challenges We Handle
Communal-to-individual heating conversion
A common job across ex-local authority blocks in Peckham, Lewisham and Croydon. We assess existing systems and any housing association permissions needed.
Larger period houses needing more radiators
Three to four bedroom Victorian and Edwardian houses in Croydon, Streatham and Tooting typically need 8 to 12 radiators rather than 4 to 6.
Riverside new-builds already pipework-ready
Greenwich and Battersea riverside developments are typically pipework-ready, so most work here is boiler replacement.
Common Questions
Can central heating be installed in an ex-council flat with communal heating?
Yes, in most cases. Converting from communal heating to your own individual central heating system is a common job across ex-local authority blocks in Peckham, Lewisham and Croydon. We assess the existing setup and any freeholder or housing association permissions needed before quoting.
Do larger Victorian houses in Croydon and Streatham need more radiators?
Yes. Larger three to four bedroom Victorian and Edwardian houses common in Croydon, Streatham and Tooting typically need 8 to 12 radiators, compared with 4 to 6 for a smaller flat.
What size boiler do I need for a South London terrace?
A typical two to three bedroom South London terrace needs a 27kW to 30kW combi boiler. Larger houses with two or more bathrooms typically need a system boiler instead.
Do riverside new-build flats in Greenwich need central heating installed from scratch?
No, typically. Riverside developments in Greenwich and Battersea are built with heating pipework already installed, so most work here is boiler replacement rather than a full system install.
How long does central heating installation take in South London?
A full installation typically takes 3 to 5 days for a Victorian terrace. Communal-to-individual heating conversions in ex-council flats can take slightly longer due to additional permissions and pipework routing.
