What Insulation Methods Do nPower’s Insulation Grants cover?

nPower primarily offers two types of insulation which you can claim through an insulation grant. These are loft insulation and cavity wall insulation, which are also considered to be the two most popular methods of insulation to install in your home. 

Cavity Wall Insulation

Whereas cavity wall insulation relates to the process of injecting insulation material into the gap between the outer and inner walls of your home. While this area also acts as a protection barrier to stop moisture from the outer wall reaching the inner wall, the gap also causes the movement of air and the loss of heat. Below, we have included a table with the advantages and disadvantages related to cavity wall insulation:

Cavity wall insulation



  • Cavity wall insulation helps your home retain heat whilst also reducing draughts.
  • With the elimination of the gap between the outer and inner wall, if moisture were to get into the inner wall, or the insulation itself, then it will not work effectively and may cause condensation and damp.
  • By retaining more heat, your house will not be as reliant on your boiler, resulting in a reduction in your energy bills.
  • Certain cavity wall insulation materials are liable to sag over time.
  • This type of insulation is considered to be cheaper than other insulation methods.
  • Poorly fitted insulation will not be as effective.
  • Cavity wall insulation is quick to install and won’t change the outward appearance of your property.
  • If the cavity between your outer and inner wall is smaller than average then the method won’t be as effective.
  • Insulated homes typically see a reduction in condensation, which can lead to the development of black mould.
  • Like loft insulation, cavity wall insulation can help soundproof your home.

Loft Insulation

As you can expect, loft insulation refers to the installation of insulation in your roof space. Typically the insulating materials will be installed between the joists or the rafters in your loft, with the aim of ensuring that the heat your home is generating does not escape via the roof. Below, we have included a table with the advantages and disadvantages related to loft insulation:


Loft insulation



  • Insulated homes tend to see a reduction in condensation.
  • Poorly installed loft insulation will not be as effective.
  • Loft insulation will make your home more energy efficient, leading to a reduction in your energy bills.
  • Your loft space will be colder as a result of the insulation, which could lead to condensation or damp issues as well as burst pipes, if left untreated.
  • Insulation will make your house warmer in the winter as you use your central heating, and colder in the summer.
  • Loft insulation can also work to soundproof your home.
  • Insulated properties also see an increase in property value compared to those that don’t feature any measures.

Am I Eligible For The nPower Insulation Grants?

The ECO4 government-backed scheme aims to reduce domestic household emissions across the UK, while also helping the UK reach its net zero emissions goal by 2050. It is through this scheme that energy companies like nPower are able to provide free insulation grants to help households become more energy efficient and reduce their energy bills. 

In order to receive an nPower insulation grant through the ECO4 scheme, you must fulfil the following criteria:

Your property must have an EPC energy rating of D or lower.
AND your combined household income must be £31,000 or less. Or at least one member of your household must be actively claiming income-related benefits.

The list of benefits that are included in the above criteria are:

Child Benefits
Child Tax Credit (CTC)
Housing Benefit (newly eligible under ECO4)
Income-based Jobseekers Allowance (JSA)
Income-related Employment and Support Allowance (ESA)
Income Support
Pension Credit Guarantee Credit
Pension Credit Savings Credit (newly eligible under ECO4)
Universal Credit (UC)
Warm Home Discount Scheme Rebate
Working Tax Credit (WTC)

If you meet the criteria, then you will be eligible to claim energy efficiency methods through the insulation grant scheme.

How Does 0% VAT On Insulation Help Me?

The UK government has applied 0% VAT on all Energy Saving Materials in the UK – and this applies to cavity wall insulation, too. First introduced in April 2022, 0% VAT on insulation is set to last until the end of March 2027.

This is automatically applied on any qualifying purchase, so you don’t have to apply through a scheme or anything – you just get to enjoy cheaper cavity wall insulation, which will help stretch those government grants even further.
