Does your home feel cold and draughty in winter, yet stuffy in the summer? It could be poor insulation costing you comfort and money. Professionally installed home insulation helps to regulate the temperature in your home, reduce heat loss, and cut hundreds off your energy bills each year.

Why insulate your home?

Homes lose heat through the roof, walls, and floors, and without effective insulation, your boiler or heat pump has to work overtime to keep you feeling comfortable.

That leads to:

  • Cold spots and draughts
  • Overheating in summer
  • High, unpredictable energy bills

Upgrading your insulation helps create a more efficient thermal envelope around your home, keeping warmth in during winter and helping your home stay cooler in summer.

Types of insulation we offer

As a highly experienced insulation and fabric installer, we offer a full range of solutions to suit all property styles and budgets. Whether you're looking to insulate your loft, floors, or walls, we’ll guide you to the right choice.

Internal wall insulation

The average 3-bed home could save around £560 a year* on heating with internal wall insulation. It adds a layer of warmth from the inside and is ideal for solid walls or room-by-room upgrades, without altering your home’s exterior.

External wall insulation

Perfect for older or solid-wall homes, external wall insulation adds a thermal layer to the outside of your property to lock in warmth. Homeowners typically save between £195–£650 a year* on heating bills.

Loft insulation

One of the easiest ways to boost efficiency. Loft insulation prevents up to 25% of heat loss and could save you up to £340 a year** on heating bills.

Underfloor insulation

Got cold floors or chilly draughts? Underfloor insulation tackles heat loss from below and is ideal for homes with suspended timber floors that feel cold underfoot.

Room in roof insulation

Room in roof insulation keeps warmth in and cold out, making your top-floor spaces more comfortable all year. It could save you up to £393.64* a year on heating costs.*

* Savings based on Ofgem estimates. Actual savings will vary depending on property type and energy usage.

Cavity wall insulation

Cavity wall insulation fills the gap between external walls, keeping in warmth where you need it most. This upgrade can save up to £370 a year** on energy bills in some homes.

** Savings based on Energy Saving Trust data as of July 2024. Individual results may vary.

Could you get insulation for free?

With energy prices still high, improving your home’s insulation could make a big difference - and it could cost you nothing.

Through schemes like the ECO4 Scheme and the Great British Insulation Scheme (GBIS), many households qualify for free or partially funded insulation, which includes measures such as loft, cavity wall, underfloor, and room-in-roof upgrades.

You could be eligible if:

  • You receive certain benefits or income support
  • Your home has a low EPC rating
  • You’re in a hard-to-heat or off-gas property
  • Even if you're not sure, it’s worth checking.
