As of 15/5/25, you can now get both free cavity wall insulation and free loft insulation together.

Do I qualify for a grant?

There are two main pathways to qualify for a loft insulation grant in Newport:

1. The General Group

To qualify under this group, you must meet two key criteria:

Council Tax Band: In Wales, your property must be in bands A, B, C, D, or E. In England, it must fall under bands A to D.
You can check your council tax band on the Gov.UK website. ✔

Energy Performance Certificate (EPC) Rating: Your property must have an EPC rating of D, E, F, or G, which can be verified on the EPC Register. ✔

2 ticks and you qualify!

These conditions apply to homeowners and private renters (with the landlord’s consent). However, private tenants must also receive a qualifying benefit to be eligible for free loft insulation, and the EPC rating of the property must be a D or E.

F or G rated rented properties, must have a legal exemption registered to qualify.

2. The “Low Income” Group

To qualify through this group, you need to be receiving one of the following benefits, and your EPC rating must be D, E, F, or G:

A full and thorough survey of the loft space is carried out, including a health and safety survey, to ascertain its suitability.

Any findings or concerns will then be discussed with you.

These could include but are not limited to, damp, ceiling cracks, high amp cables, down-lighters, wasp nests, evidence of rodents, condensation, shallow lofts with less than 1 metre head height, etc.

If Bats are present, you cannot have your loft insulated- it’s illegal. They are a protected species and must not be disturbed.

However, the loft can be insulated during their “away period”.

free Loft Insulation

We don’t use the “itchy stuff” any more.

For our free loft insulation, we use what can be described as a “quilt” which the manufacturers state “you could comfortably sleep on”.

The rolls are brought into the house in “poly bags” and taken into the loft, where the insulation is removed from the bags.

The first layer of free loft insulation is then laid between the joists. A second layer is then laid at right angles to the first layer, that is, across the joists, therefore “sealing off” the insulation below.

The recommended depth of loft insulation is 270mm ( 11 inches).

Our technicians will then ensure that there is sufficient ventilation within the loft space. Each loft will have its own set of circumstances, such as down-lighters, electricity cables, etc., but these would have been noted during the initial survey and discussed with you.

An average semi-detached house would take less than 2 hours to insulate. The empty bags are removed from the loft, and no mess to be seen.

All our technicians are fully insured.

Methodist Church, Blackwood.

Loft Insulation Wales
Methodist Church

This is a church loft that we insulated in Blackwood, South Wales.

It has a beautiful “barrel” ceiling.

It could only be done by blowing insulation into the loft space. It was potentially too dangerous to try and lay the insulation. The area of the loft was 325 sqm, which is equivalent to about 6 semi-detached houses.


We do not install “rafter” insulation. There are 2 main reasons for this.

Firstly, we just don’t see the point of it.

Yes, it stops the heat from leaving the house, but it does not stop the heat from leaving the “living space” (the bedrooms). It only serves to heat the loft space – great if you are growing plants in the loft.

However, our second reason is somewhat scary.

Rafter insulation normally takes the form of “foam insulation”, and this forms a bond with the roof. I had read horror stories online where a problem had arisen with a tile letting in water. Owing to the bond formed by the foam insulation, the whole roof had to be removed.

In August 2016, I had a call from a customer in Whitchurch, Cardiff, where that exact same situation had arisen. The customer had to have the roof replaced at a cost of £7,000.
