What and How? Understand Underfloor Insulation

Even if your walls and ceilings are insulated, up to 20% of your heating can escape through uninsulated floors. Underfloor insulation (UFI) is an essential yet often overlooked solution to energy loss. Through the UK Government’s ECO4 Scheme, you can now get this insulation professionally assessed and potentially installed for free, depending on your home’s suitability.

Underfloor Insulation Grants

Under the ECO4 funding scheme, Ranova Energy will help you determine if your home qualifies for underfloor insulation. This is a great opportunity to improve your home’s warmth and energy efficiency—especially in older properties with suspended timber floors that lose heat through the gaps beneath them.

Is Your Home Eligible?

You may qualify if:

  • You have a basement, cellar, or void beneath your ground floor.

  • Your home has ventilation or air bricks on external walls.

  • The property is sloped or raised, which often suggests a suspended floor.

A qualified surveyor will confirm your eligibility before work begins.

Cost and Savings

The typical cost of underfloor insulation ranges from £300 to £1,200, depending on property size and layout. However, under the ECO4 Scheme, you may not have to pay anything at all—with grants available to cover the full cost for qualifying homes.

 

Benefits of Underfloor Insulation:

  • ✅ Save Money: Lower your energy bills by up to hundreds per year.

  • ✅ Boost Comfort: Eliminate draughts and cold spots underfoot.

  • ✅ Reduce Carbon Footprint: Use less energy and cut your emissions.

  • ✅ Government Funding: Take advantage of ECO4 grants for energy upgrades.

Adding the Final Touches

Once insulation is installed between the floor joists, a vapour control layer is placed on top. This prevents moisture buildup and enhances insulation performance. All edges and overlaps are sealed tightly before your flooring is replaced—leaving you with warm, energy-efficient floors that feel just as great as they perform.

Looking Beyond: Consider Heat Pump Integration

For even more savings and comfort, pair underfloor insulation with a heat pump system. Average installation costs:

  • Air-to-Air Heat Pump: £1,500–£3,500

  • Air-to-Water Heat Pump: £8,000–£18,000

With up to £7,500 in ECO4 grants available, Ranova Energy can guide you through the process and help you unlock the most cost-effective energy solutions for your home.
