How Much Does it Cost to Install Central Heating in the UK?

Jump to:

Installing central heating introduces consistent warmth and comfort throughout your home. It’s a significant investment, so understanding the associated costs helps you budget effectively for this important upgrade.

What is the Average Cost to Install Central Heating?

In the UK, the average cost for installing a new central heating system ranges from £3,500 to £7,000. However, several factors determine where your project will fall within this range.

Factors Affecting the Cost of Installing Central Heating

  • Size of your home: Larger homes naturally require more radiators, a potentially larger boiler, and more extensive pipework, driving the cost upward.
  • Type of boiler: Your choice of boiler system greatly influences the price:
  • Complexity of installation: The state of your current heating setup and the accessibility of areas for piping impact labor costs. Complex or first-time installations will be more expensive than straightforward replacements.
  • Choice of radiators: Radiators come in an array of styles, sizes, and materials, impacting the price.
  • Additional features: Choosing enhancements like smart heating controls or underfloor heating increases the overall cost.
  • Geographic location: Depending on where you live in the UK, labor costs may fluctuate slightly.

What Does a Central Heating System Include?

  • Boiler: This central unit heats the water that circulates through your system.
  • Radiators: Panels installed in rooms that release the heat from the hot water.
  • Thermostatic Radiator Valves (TRVs): These valves allow for individual room temperature control.
  • Pipework: The network of pipes that carries the heated water.
  • Heating Controls: Thermostats and programmers manage the timing and temperature settings.
  • Hot Water Cylinder (Optional): Provides hot water storage for homes with system or regular boilers.

  • Smart heating controls further enhance efficiency by optimizing your heating usage.
