How Can Cavity Wall Insulation Improve Energy Efficiency?

All Posts

Ensuring that a home is properly insulated can offer a wide range of benefits relating to the efficient use of energy. Many newer houses are built with cavity wall insulation but some older homes have not had cavity wall insulation installed. The first step is assessing whether or not cavity wall insulation can work for your home. Some properties are not suitable for cavity wall insulation as a result of exposure to moisture. However, if your home is suitable for cavity wall insulation and it is professionally installed this can provide significant benefits in reducing utility bills.

Read more for some further information on the benefits of cavity wall insulation in improving energy efficiency.

Cavity wall insulation

Installation

The process of installation for cavity wall insulation typically only takes a couple of hours. This process usually involves drilling a number of holes in the wall and then using these holes to inject the insulation. The insulation will typically be made up of a material such as polystyrene beads or mineral wool. Once installed, cavity wall insulation provides long-lasting insulation and is designed not to need replacing as long as it is not exposed to moisture. In order to get the most benefit from cavity wall insulation, it is important to ensure that high-quality materials are used and that it is installed professionally by an experienced contractor.

Alternatives To Cavity Wall Insulation

If a property has persistent issues with damp then it can be worth looking into alternatives to cavity wall insulation. If a house is in an area with a high-flood risk or where weather conditions are particularly harsh then this can also lead to issues which reduce the effectiveness of cavity wall insulation. Some other effective steps which can be taken to reduce heat loss include loft insulation and the installation of double-glazed windows. With ECO4 funding, loft insulation grants are available to help make homes more energy efficient. It can also be useful to look into more efficient heating solutions. Electric storage heaters can provide one solution to this by storing energy from off-peak times.

Check Eligibility

Changes such as cavity wall insulation, loft insulation and the use of electric storage heaters can make a big difference to utility bills. If you are in receipt of government benefits then you may be entitled to an ECO4 grant. This is a government grant to help improve energy efficiency in your home. To check your eligibility fill in our form taking just a couple of minutes to complete. Alternatively, get in touch with our team to discuss your eligibility by calling 0191 466 1185.

Don't worry, many homes do not have a current EPC certificate. Let's find your address from the Royal Mail instead:

 

Your address does not have a valid EPC certificate

Don't worry, whilst your property doesn't have a current Energy Performance Certificate (EPC) we can still check your eligibility by taking some more details from you. Just click next button to proceed.

Your rating score is:

C

The lower your home's energy efficiency rating, the more money the government make available for you to improve it.

Due to the EPC rating of your property, your home's rating is unlikely to be improved by the measures we install. We are sorry that we cannot help you further in this instance.

Consent form for sharing data with the Energy Saving Trust

We need to check you are eligible for the Energy Company Obligation (ECO) and/or Great British Insulation Schemes (GBIS) and/or Land Registry (LR). To do this, for ECO and GBIS we would like to share your information with the Department for Work and Pensions (DWP) via Energy Saving Trust who will verify whether or not you are receiving the relevant benefits to be eligible for either scheme. To check the ownership of your property as registered with HM Land Registry, we need to submit your information through an online checking service provided by the Energy Saving Trust (EST). This will enable us to securely verify the property’s private ownership against the data on the register. EST will not use this data for any other purpose.

Please note that it is not possible for Energy Saving Trust or us, the company using this service, to see which benefits you are through this service. DWP will only confirm whether you are in receipt of a qualifying benefit, not which one. This will not have any impact on future benefit payments.

If you do not want us to share your data with DWP via Energy Saving Trust, you will be required to provide copies of documents that provide proof of the benefits you are in receipt of from the DWP.

If you go on to receive funding through ECO4 or GBIS your data may be audited by Ofgem and/or your Energy Supplier to ensure a valid eligibility check has been completed for you. For full information on what will happen to the data we collect about you, please refer to the privacy notices from your Energy Supplier and installer, Energy Saving Trust, DWP, and Ofgem.

By ticking the box below, and providing your details, you agree to share this data with the DWP via Energy Saving Trust.

You can contact us to withdraw your consent for us to share your data with DWP via Energy Saving Trust. If you withdraw consent, the collected data will continue to be processed, however no new data will be collected or used for further processing. We will be required to keep a record of any data already processed for the purposes of Ofgem audits however your data would only be audited in cases where you have received funding from ECO4 or GBIS. Data relating to ECO4 and GBIS eligibility checks will be retained until 30 September 2026 unless otherwise notified by Ofgem.
