Insulation Extraction Grants News
CAVITY WALL INSULATION
We are the largest manufacturer of EPS bonded bead CWI in the UK. Our products are installed in over 800 homes per week.
All our installers are NVQ2 qualified insulation specialists and we have been operating for over 50 years.
We also manage grant funding for homeowners in Northern Ireland under the Northern Ireland Sustainable Energy Programme (NISEP), ensuring affordable cavity wall and loft insulation is available to people throughout the Province.
Is my house suitable for CWI?
If your home has a cavity with a minimum 40mm gap, it may be suitable. Our surveyors can assess the walls and recommend what steps to take to insulate.
How long will it take to install CWI?
It usually takes our trained operatives around two hours on site to complete an installation but, it can take longer for large houses.
How much will I save on heating?
According to the NI Energy Savings Trust (as of Jan 2025) the amount saved on your heating bill depends on the size of your house and heating type but, typical homes can save up to £250 a year.
Are there grants available?
In Northern Ireland there are grants available through the NISEP scheme. Contact us to see if you may be eligible.
ENHANCES existing homes
Up to 35% of a home’s heat is lost through uninsulated walls. That’s why energystore have insulated over 400,000 homes in the past 50 years! Our technical experts will help you to assess whether your property is suitable for cavity wall insulation to be installed.
STAY WARMER FOR LONGER
Insulating your home creates a buffer so heat can’t escape through your walls. If your home is able to retain the heat, it takes less time to comfortably heat your home and it stays warmer for longer. These factors can help reduce your fuel bills.
Help the environment
