Free Cavity Wall Insulation Grants in Cardiff, Swansea, Bridgend, Caerphilly,
Newport and throughout South Wales.
Is Free Cavity Wall Insulation really available throughout South Wales?
Under the Cavity Wall Insulation Grant scheme, Cavity Wall Insulation is Free in 99% of the cases for those that qualify for the Grant.
The Enhanced Cavity Wall Insulation Grant qualification, has been broadened and many people who did not qualify for this Grant in the past, will now qualify.
There is also a new Cavity Wall Insulation Government Grant scheme available which is based on where you live, but is not based on benefits.
We would of course be pleased to give a quote to those that do not qualify for a grant on either scheme.
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.
Water resistance — “SuperBead” cavity wall insulation will resist the transfer of water across the cavity, so no damp caused.
Condensation — “SuperBead” cavity wall insulation will contribute to limiting the risk of condensation because the internal 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. There are about 30% fewer holes than using fibre, and the holes are smaller. This leaves a “solid” blanket of polystyrene wrapped around your home, and reduces 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, and have approval for use in even the most extreme of conditions.
As a part of the initial survey we also carry out a CAS + ISA (Cavity Assessment and 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 Grant scheme.
How is Free Cavity Wall Insulation Funded?
The Government have massive European targets to reduce Carbon Emissions, so they 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 a 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
But it is not as simple as that.
As a part of the initial survey we also carry out a Cavity Assessment Survey (CAS). This is a PAS2030 and OFGEM compliant survey, with an Independent Surveillance of the Assessment (ISA) by CIGA (the underwriter of the 25 year guarantee).
The suitability of the walls to be insulated will be assessed by way of an extensive survey of the property.
This survey includes drilling a small test hole into the wall of each elevation. A borescope will be inserted into each hole and the cavity will be examined. Photographs of the cavity will be taken, along with measurements of the depth of the cavity.
All walls are carefully examined and any remedial work noted , such as cracks, unfilled holes, etc. This remedial work has to be completed before the walls can be insulated
Gutters and down-pipes are examined for any leaks, blocks, or spillage and proper drainage.
The survey will take about 2 hours, and is free of charge.
The report and photographs are then uploaded to the CIGA platform for auditing.
This is a part of the greatly improved quality control measures found within the new free Cavity Wall Insulation in Wales Grant scheme.
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 CAS + ISA 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 CAS + ISA 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 semi-detached house with easily accessible walls. It is simple, quick – and with no mess.
Cavity Wall Insulation can reduce the amount of heat escaping from your home by up to 35%. This is 70% of the heat lost through the walls. It can also reduce carbon 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.
Our Installers are among the best in the business. They have been insulating cavity walls for the past 45 years. They will make good the holes with closely-matching filler. You will have a first-class result with the minimum of fuss and disruption. Most of our customers are amazed at how quickly and neatly this operation can be carried out. Our work is also guaranteed for 25 years by CIGA – the Government backed Cavity Insulation Guarantee Agency.
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, and peace of mind.
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 so if they do occur, CIGA has the expertise to ensure that they are swiftly rectified. The new CAS + ISA survey will also reduce the potential for future problems, because only suitable walls will be insulated.
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.
