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.
