Free or subsidised insulation through CERT.
The Carbon Emissions Reduction Target (CERT) scheme provides reduced cost and sometimes free loft and cavity wall insulation and is paid for by the ‘big six’ energy companies (British Gas, EDF Energy, nPower, E.ON, Scottish and Southern Energy, and Scottish Power) but you don’t have to be one of their customers to benefit. Anybody can qualify for a discount for the total cost of cavity wall and loft insulation under this scheme regardless of their income or savings, typically there is around a third or more off the cost. Applicants must be home owners or have the permission of their landlord and are designated as being in one of two groups: ‘Able to Pay’ or ‘Priority’.
Able to Pay
If the applicant is not on benefits and/or under 70 they are classed as Able to Pay. This means that the client, if a homeowner, pays an amount towards the cost of the insulation (see Table 1) with the remainder being subsidised by the energy companies.
Priority
Under the CERT scheme, people over 70 or on various benefits and allowances qualify to have cavity wall and/or loft insulation for free unless the property is larger than average for its type (see Table 2 for sizes). The following benefits and allowances qualify for Priority funding:
Council Tax benefit (not 25% single occupancy discount)
Housing benefit
Income support
Income-based job seekers allowance
Attendance allowance
Disability living allowance
War disablement pension (must include a mobility supplement or a constant attendance allowance)
Disablement pension (must include constant attendance allowance)
State pension credit
Child tax credit and the household income is £15, 592 or less
Working tax credit and the household income is £15, 592 or less
or
Aged at least 70

There is an excess of £4.21 (inc. VAT) per additional square metre for cavity wall insulation and £5.26 (inc. VAT) per additional square metre for loft insulation. This means there is an additional £5.26 for every square metre over the free square metre allowance. Some examples will help explain what this means:
- Example 1 (using Table 1).
A homeowner – classified as Able to Pay – could have 95m2 of cavity wall insulation or 50m2 of loft insulation installed for £129 if the depth of the loft insulation they have currently is less than 60mm (2.63”).
- Example 2
If their loft had an area of 50m2 but an existing depth greater than 60mm it would cost £199.
N.B. Because the loft had more than 60mm of insulation, increasing its depth to 270mm is classed as a top-up. The reason why a top-up is more expensive than getting the full 270mm is that although both procedures are subsidised by the ‘big six’ energy companies, top-up saves less carbon and so it is subsidised less. This means the installer get less money from the energy companies when doing a top-up and has to pass the cost onto the customer.
- Example 3
A loft with an area of 60m2 and a current depth greater than 60mm would cost (60-50) x £5.26 + £199 =£251.60.
- Example 4 (using Table 2).
If the homeowner is given Priority status and lives in a semi-detached, three bedroomed house and has a loft with an area of 50m2 with less than 60mm/2.63” of insulation, they would get the loft insulation for free.
- Example 5
If all the parameters remain the same except we increase the area to 75m2 they would get the first 50m2 for free as before, but they would have to pay the loft insulation excess of £5.26 for each m2 over the 50m2 limit. Meaning they would pay (75-50) x £5.26 which is £131.50.
Draught-proofing
Our preferred insulation installer will also draught-proof one external door for free for Priority customers if insulation is installed on the same day. To draught-proof a second external door (Priority) costs £20. Able to Pay customers pay £20 per door.
