Cavity Wall Insulation Bristol Grants in Bristol, Bath, Gloucester, Taunton and throughout the South West.

Is Free Cavity Wall Insulation really available throughout Bristol and  the South West?

The Enhanced Cavity Wall Insulation Grant qualification,has been broadened. Many people who did not qualify for this Grant in the past, will now qualify, including those in receipt of child benefits/family allowance.  Click here to see what benefits qualify you for a higher rate Government Grant.

An average 3 bedroom semi-detached house will take about 3 hours to insulate.

The average “cash price” for installing cavity wall insulation into a 3 bedroom semi-detached house is close to £1,000. A customer contribution of £100 means the Government Insulation Grant is still covering 90% of the cost.

If you do not qualify for a Grant we would be happy to give you a quote as a paying customer.


What Free Cavity Wall Insulation do we use?

We always install “SuperBead” Polystyrene Beads and not “RockWool” (fibre). Polystyrene Bead is a superior material for insulating Cavity Walls, but it is more expensive. “SuperBead” cavity wall insulation has been certified for the following.

Thermal properties — “SuperBead” cavity wall insulation has a declared thermal conductivity of 0.035, so it will keep the heat in.

Water resistance — “SuperBead” cavity wall insulation will resist the transfer of water across the cavity and prevent damp.

Condensation — “SuperBead” cavity wall insulation will contribute to limiting the risk of condensation because the inside walls will be warmer .

Behaviour in relation to fire —  “SuperBead” cavity wall insulation does not prejudice the fire resistance properties of the wall.

Durability — “SuperBead” cavity wall insulation is durable, rot-proof and water resistant. It is sufficiently stable to remain effective as an insulation for the life of the building

“SuperBead” cavity wall insulation is up to 20% more efficient than fibre insulation. The insulation is blown into the cavity with an adhesive which “goes off” in about 20 minutes. This leaves a “solid” blanket of polystyrene wrapped around your home, reducing heat loss through the walls by about 70%.

The beads have been thoroughly tested and will not deteriorate over time. They are fully fire resistant. They have approval for use in even the most extreme of conditions.

As a part of the initial survey we also carry out a CASS (Cavity Assessment Surveillance Scheme) survey. The suitability of your walls to be insulated will be assessed. This is part of the much improved quality control measures found in the new free Cavity Wall Insulation Bristol Grant scheme.

How is Free Cavity Wall Bristol Insulation Funded?

The Government have (for at least another couple of years) massive European targets to reduce Carbon Emissions. The Government, as Governments do, passed the buck. They gave a Legal Obligation to the Gas and Electricity companies to reduce Carbon Emissions. This is know as the Energy Company’s Obligation, ECO for short.

The system was simplified in April 2017, with energy assessments being no longer required. Instead, the Government have “deemed” an amount of Carbon Emission savings for each type of property – terraced, semi-detached, detached, etc. These Carbon Emission savings are then sold to one of the Gas and Electricity companies. That is how it is funded. We all pay an amount on our fuel bills towards this fund. So yes, we pay for it in the end, as usual.


Are my Cavity Walls suitable for insulating?

Houses built after 1925, are likely to have external walls are made of two skins of brick. There would be cavity between them. The two walls would be held together with wall ties.

Insulation for Cavity Walls fills that gap, keeping the warmth in – thus saving energy. It can also help reduce condensation inside the house if this is a problem on your external walls.

Your home will usually be suitable for cavity wall insulation if:

  • the external walls have an unfilled cavity
  • your cavity is at least 50mm wide
  • the masonry or brickwork of your property is in reasonably good condition
  • properties built after 1982 now qualify for a grant 


What if there is damp in the house?

If there are any damp patches on your external walls then they should not be insulated. The cause of the damp has to be resolved first. In fact, if there is damp, the property will fail the CASS survey. Therefore, we will not be able to install cavity wall insulation into damp walls. To qualify for a Grant there must be a 25 year guarantee. To obtain a 25 year guarantee, the property must pass a CASS survey. So if there is damp there is no Government Insulation Grant – simples.

If it is “Black Mould / Spots” then this is probably Condensation and not Damp. Statistics show that most of the time Condensation is a lifestyle issue rather than a structural issue. However, Cavity Wall Insulation can help reduce/eradicate Condensation by keeping the internal walls warmer.


How is Cavity Wall insulation installed?

Filling cavity walls is not a job you can do yourself. We do the job in around 2-3 hours for an average house with easily accessible walls. It is simple, quick – and with no mess.

Cavity Wall Insulation Bristol can reduce the amount of heat escaping from your home by up to 25%. This is 70% of the heat lost through the walls. It can also reduce CO2 emissions by up to 3 tonnes per year.

  • Most homes built of brick
  • Blown into the gap between two skins of brick.
  • Installed from the ground floor to the roof.

Peace of Mind

The Cavity Insulation Guarantee Agency provides independent 25 year guarantees for Cavity Wall Insulation fitted by registered installers in the UK and Channel Islands.

Government regards cavity wall insulation as the most effective energy savings measure that most people can do to their homes”. 

It is a major contributor to reducing carbon emissions.

The Cavity Insulation Guarantee Agency was established with the Energy, Environment and Waste Directorate. They provide householders with an independent, uniform and dependable guarantee covering defects in materials and workmanship.

Independent research carried out for the Department of the Environment, Transport and the Regions (DETR) has confirmed that
the insulation of cavity walls is a very reliable process.

Problems are therefore extremely rare. If they do occur, CIGA has the expertise to ensure that they are swiftly rectified. The new CASS survey will also reduce the potential for future problems, by only insulating walls that are suitable.

CIGA also administers the Cavity Wall Insulation Self Certification scheme (CWISC) in association with the British Board of Agrément. The scheme provides the comfort of knowing that work by registered contractors complies with the requirements of the Building regulations.
