  • Heating cables and mats
  • Foil systems for carpet and vinyl
  • Loose wire systems
  • In screed heating solutions

2. Wet Underfloor Systems

Our wet underfloor heating systems use warm water underfloor heating connected to your gas boiler or heat pump:

  • Water-based system networks
  • Integration with condensing boiler systems
  • Compatible with heat pumps for greater energy efficiency

Underfloor Heating Costs Breakdown

What’s the Average Cost of Underfloor Heating in London?

The average cost of underfloor heating in London can vary significantly based on several factors, including the type of heating system, the size of the area to be heated, and the level of insulation in your home.

On average, you can expect to pay between £60 and £135 per square meter for underfloor heating installation. For smaller, straightforward projects, the total cost might be a few hundred pounds.

However, for larger, more complex installations, such as whole-house systems, the costs can escalate to around £10,000. This range reflects the diversity of underfloor heating projects, from single-room installations to comprehensive home heating solutions.

Electric Underfloor Heating Costs

Electric Underfloor Heating Installation Cost:

  • To install electric underfloor heating, basic heating mats cost £75-100 per square metre
  • Installing electric underfloor heating cables: £80-120 per square metre
  • Professional installation: Additional £200-300 per day

Running Costs for Electric Systems:

  • Average energy bills: 8-12p per kWh
  • Typical bathroom: £25-35 Monthly
  • Smart heating controls can prevent unnecessary heat usage

Wet Underfloor Heating Costs

Wet System Installation Costs:

  • New build: £100-150 per square metre
  • Retrofit with existing gas central heating system: £150-200 per square metre
  • Integration with gas boilers or heat pumps: £750-1,200

Running Costs for Wet Systems:

  • More energy efficient than traditional radiators
  • Lower heating bills compared to electric systems
  • Costs vary depending on your heat source (gas boiler or heat pump)

Initial Investment vs Long-term Savings

While the initial investment for installing underfloor heating might seem substantial, it’s important to consider the long-term savings. Underfloor heating is known for its efficiency, potentially reducing energy bills by up to 25% compared to traditional radiators. This efficiency stems from the even heat distribution and lower operating temperatures required. Additionally, underfloor heating can enhance the value of your property, making it an attractive feature for future buyers. Thus, the upfront costs can be offset by the long-term financial benefits and increased property value, making it a smart investment for homeowners.

Running Costs of Underfloor Heating

The running costs of underfloor heating are influenced by the type of system you choose and the insulation quality of your home. Generally, underfloor heating systems are more cost-effective to run than traditional radiators. For instance, the average monthly cost to run underfloor heating in a typical 4m² bathroom is around £10. This efficiency is due to the lower operating temperatures and the even heat distribution that underfloor heating provides. By optimising energy use, underfloor heating can help keep your monthly energy bills manageable while maintaining a comfortable home environment.

Choosing Between Electric and Water Systems

Perfect for Electric Underfloor Heating:

  • Single room installations
  • Properties with good insulation
  • Homes with existing central heating
  • Projects requiring minimal floor height

Ideal for Wet Underfloor Systems:

  • Whole house heating
  • New builds with heat pump installation
  • Properties upgrading from gas central heating system
  • Larger spaces seeking energy efficiency

Underfloor Heating vs Radiators

When comparing underfloor heating to radiators, several factors come into play. Underfloor heating offers a more efficient and comfortable heating solution, especially when paired with modern boilers or energy-efficient heat pumps. Unlike radiators, which can create hot and cold spots, underfloor heating provides consistent warmth across the entire floor surface. This not only enhances comfort but also improves energy efficiency. While radiators might have a lower initial installation cost, underfloor heating can lead to significant long-term savings and a more pleasant living environment.

Heating Efficiency and Cost Comparison

Underfloor heating operates by emitting heat evenly across the floor, creating a gentle and consistent warmth throughout the room. This method of heating eliminates the hot and cold spots often associated with radiators, resulting in a more comfortable living space. In terms of efficiency, underfloor heating systems, particularly when used with modern boilers or energy-efficient heat pumps, outperform traditional radiators. The average cost of running electric underfloor heating is around £2.90 per hour, while a water-based system costs about £2.10 per hour. In contrast, running radiators can cost approximately £3.50 per hour. Although underfloor heating systems may require a higher initial investment, the long-term savings and increased property value make them a worthwhile consideration for homeowners looking to enhance their heating efficiency.
