Green Homes Grant Voucher Scheme UPDATE


As you may be aware, the Government has ended applications for funding for loft insulation through the Green Homes Grant Voucher Scheme.

At DKM Developments Ltd we are proud to have helped at least 100 homeowners by quoting for installations and supporting their applications for funding. Luckily as these were submitted before the scheme ceased taking new applications they should be honoured.

This means that we can still help our existing customers get the grant money and have their installation completed.


We are just in the process of becoming accredited for ECO for loft insulation installation and other measures (e.g. room in the roof) so please get in contact with us for any home energy improvement that you are considering and we will see how we can help you.

For more information about the ECO scheme click here.

At DKM Developments Ltd we offer an energy improvement retrofitting service. This includes standard loft insulation upgrades to meet the regulation minimum 270mm requirement.

Green Homes Grant Voucher Scheme.

As approved installers with the BBA for Trustmark we are proud to be able to offer our installation service for loft insulation. This measure is covered by the Government Green Homes Grant Voucher Scheme (GHGVS). All homeowners who are eligible can claim up to two thirds of the cost of the installation of this measure. Some may be able to claim all of the cost depending on your personal circumstances. Get in touch today to organise a FREE survey and help with claiming your voucher.

The video below explains how the scheme works:

Our services.

In the first instance a qualified and accredited Retrofit Energy assessor will carry out a professional survey of your loft. The purpose of this survey is to find out what type of loft hatch is in place, the level and condition of the existing insulation, inspect the roof for any possible defects, identify pipes that will need lagging as well as any hazards such as wasps nests, asbestos tanks, pipes, ductwork etc… and evidence of any pests or protected species.

If your loft insulation is currently less than 270mm it is not being as effective in reducing heat loss as it could be. We recommend upgrading to 280mm as a minimum.

If your loft is boarded and used for storage then this will need to be cleared out prior to the installation. We offer a full loft clearance service in addition to the installation of insulation.

Once the survey is completed we will carry out a risk assessment, prepare a method statement and provide a quotation for your consideration. We will also be able to guide you through the process required to obtain government finance such as the Green Homes Grant Vouchers.

If you accept the quotation we will book in a time to carry out the installation. We will take a deposit to secure the work. If, for any reason you wish to cancel then your deposit will be returned to you under our deposit protection scheme guarantee.


On the day of the installation we will arrive and carry out the works agreed with yourselves. This includes protecting your stairs, landing and any other floors with protective sheeting. removing any rubbish, boarding and disposing of this. Upgrading the existing loft insulation to a minimum of 280mm, draught proofing the loft hatch and issuing a certificate of installation pinned to the rafters in the loft as well as warning signs.

We then take any waste materials away from your home, remove our protective sheets and vacuum floors.
