What affects the price
- •Number of radiators and the size of the property.
- •Whether pipework already exists or has to be run from scratch (lifting floors, chasing walls).
- •Boiler type and brand.
- •Controls — a smart thermostat and thermostatic radiator valves add cost but improve efficiency.
- •Making good floors, plaster and decoration afterwards.
Regional price variation
Labour is the biggest regional swing. London and the South East typically run 20–30% above the national average, while the North of England, Scotland and Wales tend to sit 5–15% below it. Material prices are fairly consistent nationwide — it is day rates that move the total. The ranges on this page assume South of England pricing unless stated.
