What is a loft insulation top-up?
Before we quote we measure the existing layer in several places and check its condition. If it is dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.
- Cross layer to a total of 270 to 300 mm
- Eaves ventilation kept clear
- Tank jacket and pipe lagging in the loft
Why book with us in Gwent
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
How much does a loft insulation top-up cost in Gwent?
Installing insulation in a home is zero-rated for VAT until 31 March 2027 and 5% after that, under HMRC's rules for energy-saving materials (notice 708/6). The Energy Saving Trust puts a typical professionally installed loft at about £750 from bare joists, or £600 to top up from 120 mm.

Questions about a loft insulation top-up in Gwent
Can you quote for several properties in Gwent?
Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.
Do you cover the whole of Gwent?
Yes. We cover every town and village in Gwent, including Newport (Gwent), Cwmbran and Pontypool.
Can new insulation go on top of old insulation?
Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
