What people say

Helen M.
I was surprised to discover my home was eligible for the scheme, as I’d never thought about improving its insulation before.
Clive B.
Free Insulations were great – they took care of everything. I only filled out a quick form, and they did the rest. Thanks Dom!
Ash J.
For once, I can’t wait for winter to roll around. I’m excited to see how much I’ll save on my energy bills now that Free Insulations have improved my home.
Jason P.
I rent, so was unsure whether I’d be eligible. Luckily, my advisor Liam was able to work around that with my landlord.
Ben T.
The process was quick and easy and my insulation was fitted in no time at all. Very happy with the service.
Alice R.
I knew about the ECO3 scheme but was confused by the options. Using Free Insulations made everything much simpler. Thank you.

Frequently asked questions

ECO4 is a four-year scheme and is intended to run from 1 April 2022 to 31 March 2026.The main objective of ECO4 is to improve the least energy efficient housing stock occupied by low income and vulnerable households. Major energy suppliers are obligated to provide homes with energy-saving measures ranging from boiler replacement to cavity and loft insulation.

Under the UK government’s ECO4 scheme, the installation of home insulation is free of charge for the end-user (you). The costs are covered by a grant from the government, which is paid to us for the service. We’ll never ask for any payment details from you as a result.

The exact criteria for the ECO4 scheme depend on numerous factors. The main ones are that you’re a low-income or vulnerable household, your home’s current insulation and heating setup, and its energy rating. This must be C (not all eligible), D, E, F, or G.

Our insulation scheme is available to homeowners and rental tenants, but tenants must get the landlord’s permission before we can begin. Please complete the contact form above for more information on your specific circumstances.

The exact job time ultimately depends on the size of your home. The application process can take a few weeks depending on how quickly we can come and survey your property. Installation of loft and cavity wall insulation usually takes a day or two, but can be more if you have a larger home.

The ECO4 grant money comes directly from the government’s scheme, although the actual support comes from an energy supplier. We get paid directly by the scheme, so you don’t have to worry about paying anyone anything.
