Insulation Solutions for Every Home

Not sure which type of insulation is right for you? Here's a plain-English guide to what we offer — and why it matters.

Loft Insulation

Save up to £255/year

One of the easiest ways to cut your heating bills — and most UK homes don't have enough of it.

Up to 25% of the heat in your home escapes through the roof. If your loft isn't properly insulated — or the insulation that's there is old and thin — you're quite literally paying to heat the sky.

IHI installs loft insulation to the government-recommended 270mm depth, ensuring your home reaches its maximum energy efficiency. Most jobs are completed in just one day with minimal disruption.

Saves up to £255 per year on energy bills
Keeps your home warmer in winter, cooler in summer
Reduces your carbon footprint
Improves your home's EPC rating
Installed to 270mm depth
Typically completed in a single day

Room in Roof Insulation

Year-round comfort

Got a converted loft or a room in your roof space? Standard loft insulation won't cut it — here's what does.

If your home has a room built into the roof space — such as a loft conversion, dormer, or rooms in a chalet-style property — standard loft insulation simply isn't suitable. These spaces have sloped ceilings, walls, and unique shapes that need a different approach.

Room in roof insulation creates a warm, well-insulated envelope around the entire space — stopping heat escaping through every surface.

Keeps loft rooms comfortable year-round
Reduces heat loss through sloped ceilings & roof walls
Cuts energy bills in hard-to-heat spaces
Improves the usability of upstairs rooms
Fully installed by certified professionals

Internal Wall Insulation

Save up to £400+/year

Own an older home with solid walls? Internal wall insulation could slash your heating bills by up to £400 a year.

Most homes built before the 1920s have solid walls — meaning there's no gap to fill with insulation. These thick stone or brick walls can lose enormous amounts of heat.

Our solution fits insulating boards to the inside of your external walls, finished with fresh plasterboard and plaster — a neat, clean result that blends seamlessly with the rest of your home.

Can save up to £400+ per year on energy bills
Prevents up to 35% of heat loss through walls
Helps reduce damp and condensation
Leaves a clean, freshly plastered finish
Ideal for pre-1920s solid-wall properties
Increases your home's EPC rating and value

FAQ

Got Questions?

Everything homeowners usually ask us before getting started.

Possibly. Many older homes have insulation that was installed decades ago and is now well below the recommended thickness. Current guidelines recommend a minimum of 270mm — if yours is thinner than that, topping it up could make a real difference to your bills.
