Free Insulation Available to UK Households In 2024

In the ongoing quest to increase energy efficiency in UK households, the government has introduced the Great British Insulation Scheme, formerly known as ECO+. This initiative aims to provide free insulation to 300,000 households, marking a significant stride towards the government’s goal in tackling fuel poverty, achieving Net Zero and reducing energy consumption in buildings and factories by 15% before the year 2030.

Key reasons for home insulation:

  • 15% of the UK total carbon emissions are attributed to residential homes.
  • The UK ranks lowest in Europe when it comes to the energy efficiency of its residential buildings, particularly in terms of insulation.
  • 8, 000 pensioners lose their lives every year due to the health implications of living in cold homes.
  • 5 million households in the UK are experiencing fuel poverty, struggling to afford basic heating needs.
  • By investing in the insulation of UK homes, we not only reduce energy consumption but also reduce energy bills.
  • Improved insulation reduces the need for constant heating, contributing significantly to the reduction of carbon emissions from households.


Who qualifies for the free insulation?

Unlike the ECO4, this free insulation scheme is available to a wider group of people. It is targeted to two types of groups: the “low-income group” and “the general group”. If your home has an Energy Performance Certificate (EPC) rating of D or lower and falls within the lower council tax bands (A to D in England, and A to E in Scotland and Wales), you could be eligible for this scheme.

The scheme focuses on specific insulation types. Popular types Include:
  1. Cavity Wall Insulation: Homes constructed between 1920 and 1990 commonly feature a gap between internal and external walls. Introducing insulating material into this cavity effectively stop cold air coming in, ensuring the retention of warm air. However, important to know that this method may not be suitable for all housing types.
  2. Loft Insulation: A quarter of a home’s heat can escape through the roof. Laying mineral wool beneath the rafters serves as an effective solution. Alternatively, insulating the loft by placing mineral wool between the beams on the floor also achieves heat retention. For those with less than eight inches of insulation, adding an additional layer proves advantageous.
  3. Solid Wall Insulation: This technique entails the installation of insulation material on the interior or exterior walls, subsequently concealed by another layer for decorative purposes. External wall insulation might necessitate planning permission, making it a rewarding process. Find out more


Embracing insulation, particularly loft and cavity wall insulation, can translate to substantial savings on heating bills, potentially amounting to £100s annually. And most importantly reduce CO2 emissions

We are a privately owned block of 30 leasehold apartments on 5 levels, Tax band B and C , EPC (10xC; 2xF; 2xE; 16xD), mixture of tenants renting from private landlords and owners occupiers. We are predominantly low income households.Our local authorities – West Sussex County Council and MidSussex District Council do not participate and has no intention to participate in ECO4 and GBIS Flex.
Different apartments have different energy suppliers, and we cannot get referral via local authority.
There is no incentive for any one of energy supplier to insulate the entire block of flats.
