Cavity wall insulation

Around 35% of all heat loss occurs through the walls of your home. However, a fully insulated cavity can save an average household up to £210 a year*.

There a multiple type of blown cavity wall insulation available in the UK. Our partners install some of the highest performing products available which reduce the risk of condensation and provide the maximum amount of potential savings. We recommend ‘Bonded Bead Insulation’ is an oil-based, waterproof product which is injected within the cavity walls and bonded with a glue to form a solid structure however allows water to pass through it into your homes damp proof course. Following the installation of Cavity Wall Insulation, you will be issued with a 25 year insurance backed guarantee

Cavity Wall insulation extraction

Unfortunately, due to a combination of factors including rogue installers, there are many properties in the UK that have cavity wall insulation installed that were unsuitable for the measure. This has led to a number of problems across the country, including damp and condensation.

Thankfully injected insulation can be extracted from within cavities and replaced with Bonded Bead Insulation providing that the property is suitable.


Wind and driving rain against exposed brickwork can damage bricks, or more commonly, the pointing, allowing water through the wall and into the cavity. Some of the materials used in the past, particularly anything fibre-based, can absorb and hold this water, allowing it to cross the cavity to the inner walls of the home, causing damp problems. In addition, if a property does not have a Damp Proof Course (DPC) cavity wall insulation is not suitable. Coastal areas are the most effected


Extracting the cavity wall insulation is a quick, clean process, completed from the outside of the property. Compressed air is blown into the wall through drill holes, and the insulation is removed via strategically removed bricks at the bottom of the wall. Once the process is completed, the brickwork is repaired and Bonded Bead Insulation is reinstalled into the property. For properties / walls that are highly exposed products such as ThermiDry can be applied to the external wall which provides a waterproof barrier to stop driving rain penetrating through the walls into the cavities whilst still allowing the cavity to breathe.

Solid wall insulation

For homes where cavity wall insulation is not an option, solid wall insulation is another viable solution.
There are two types of wall insulation; external and internal.

External wall insulation

A system of insulation boards and render is applied to the outer walls, refreshing the look of the property and improving the insulation and draught-proofing properties internally as well.

Internal wall insulation

Perfect for those who are unable to alter the outside of their house for any reason (for example the building is listed, or the house is in a conservation area and unable to get planning permission), internal wall insulation applies a system onto the internal walls on a room by room basis, creating a dry-lined, insulated internal wall. All fixtures and fittings are put back as new, with the new wall taking around 10cm of space from the existing wall.

Loft insulation

Around 25% of heat escapes through the roof and according to the Energy Saving Trust, a typical detached house could save up to £215 by installing loft insulation. It is one of the quickest and easiest ways to make your home more energy efficiency. Although most homes have some form of insulation, not all have the correct amount.

Room in roof

Around 25% of all the heat is lost in an un-insulated room in the roof. You could save you up to £400 a year on your fuel bills by adequately insulating yours*.

If you have a Room in Roof/Loft Room, it may not be properly insulated, especially if it is an older property. A room-in-roof if defined by having a permanent, fixed stair case to your loft room which is heated and has a window. Roof rooms are often difficult to keep warm in the winter and can get uncomfortably hot in the summer.

Room in Roof insulation is for dedicated loft rooms not boarded storage spaces. Room in Roof insulation is a combination of measures, ensuring that all ceilings, eaves, and sloping rooves are correctly insulated.
