Why Choose Us
The Benefits of
Proper Home Insulation
At SEF Ltd, we offer expert insulation and exterior cleaning services backed by 50+ years of experience. Our trusted, Checkatrade-approved team provides tailored solutions that enhance your home’s efficiency, comfort, and value.
Improve your EPC rating
Adding insulation or upgrading it can make a big difference to your home’s EPC rating (Energy Performance Certificate), an indication of how much it costs to heat and light.
Add value to your property
A good EPC rating as a result of proper insulation can make a property more appealing to prospective buyers and therefore add to its value.
A healthier home
A well insulated home is much more comfortable and will avoid many of the issues with damp and mould that are experienced in less well insulated homes.
Reduce Your Energy Need
With an energy efficient home, you’ll retain far more heat, therefore requiring far less energy to keep it warm.
Lower your energy bills
With better heat retention and less energy waste, your energy bills will be lower as a result, sometimes by as much as 50%.
Reduce carbon emissions
A properly insulated home means a much reduced carbon footprint, so it’s a plus for the environment.
We Have You Covered
Fully Managed Project
Many insulation solutions and energy efficient improvements that we provide currently have zero VAT applicable, saving you 20% on the actual cost of the installation. Act now as the incentive won’t last forever – with the 0% applicable only up to the end of March 2027 – after which it will revert to a reduced rate of 5%.
You can rest assured that your installation will be managed by us from start to finish. From the initial contact to the survey and the installation, we’ll handle it all, ensuring you won’t have to get involved and will have peace of mind during the whole process.
