British Gas cavity wall insulation explained

British Gas customers can now receive grants for home improvements if their home qualifies, such as new insulation for the loft and cavity walls and grants for electric heating upgrades such as electric storage heaters, among others.

This means you can have some work done on your home to improve its energy efficiency targets, and it won’t cost you a penny!

If you’re eligible for the grant, the work will be paid for through your energy supplier like British Gas, thanks to the Energy Company Obligation scheme initiated by the UK government.

Does BritishGas do free cavity wall insulations?

Yes. Among other UK energy suppliers like EON, EDF energy or Scottish Power, for example, BG participates in the government’s Energy Company Obligation (ECO) program and therefore is obligated to issue grants for home improvements.

Similarly to Carbon Saving Obligation, the ECO scheme is designed to support low-income households. You might be eligible for the new scheme if you receive one of the qualifying benefits. The process of having free loft and cavity wall insulation by British Gas is straightforward for homeowners, but it can be a little more complicated for tenants due to your landlord’s legal obligations.

This service is completely free. The installation time depends on what work is being done as well as your home’s technical requirements.

How is cavity wall insulation done?

Cavity walls (exterior walls and interior ones as well) are typically insulated by drilling a series of small holes in the mortar at regular intervals (around 25mm across) and then injecting the insulating material into the cavity.

After the British Gas wall cavity insulation is installed (or any other suppliers, for a matter of fact), the holes are refilled.

In some circumstances, a telescopic lance system for walls is used.

A new-build property will usually have rigid insulated boards installed into the wall cavities as part of the construction process.

The pros and cons of the Cavity wall insulation:

The pros and cons of cavity insulations are often debated online, and people tend to have different opinions, depending on their experiences and whether it’s done for BG customers or other energy companies.

If your house meets the following criteria, it is likely that it will be eligible for a standard British Gas cavity wall insulation grant:

The walls of your home are probably already insulated if it was built in the last 20 years or so. If you’re not sure whether you have unfilled cavity walls or so, you can contact your local authority’s building control department to find out. Another option is to have a registered installer or chartered surveyors perform an inspection at a convenient time by drilling a small hole in your external wall to find out if your walls are hollow or filled.

  1. There are no filled cavities in its external walls.
  2. The cavity is at least 50mm wide as well as clear of debris.
  3. Your property’s masonry or brickwork is in good condition.
  4. There is no risk of flooding at your house.

Installers will conduct a free survey to determine whether your house is suitable for British Gas free cavity wall insulation.

Does my house have cavities?

Cavity walls are made up of 2 brick layers with a cavity between them. Insulated cavity walls can be accomplished by inserting insulation into the spaces between them.

Solid walls are often reinforced with bricks placed across them rather than along them. From the front, these look like half-sized bricks. A cavity wall is built with bricks laid in the same direction so that they all appear the same size.

Your home was probably built with cavity walls if it was constructed after 1920. If your house was built in the last 20 years, the cavity walls were probably insulated during construction.
