What is raised loft boarding?
Laying boards straight onto the joists compresses the insulation to the joist depth, which can halve its value, and can trap moisture under the boards. Loft legs screw to the joists and carry the boards at the right height. More about raised loft boarding.
- Full-depth insulation under the boarded area
- Loft legs fixed to the joists
- Moisture-resistant chipboard or OSB boards
Why book with us in Lisburn
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
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.
No pressure selling
You get everything in writing and decide in your own time.
How much does raised loft boarding cost in Lisburn?
This work is not an energy-saving material for VAT, so it is standard-rated if VAT applies. Where it is done alongside insulation, the quote shows each part separately.
Building regulations in Northern Ireland
Northern Ireland has its own Building Regulations, with energy guidance in Technical Booklet F1. Upgrading loft insulation may count as a thermal alteration, so check with your council's building control. How the rules work across the UK.
Questions about raised loft boarding in Lisburn
Do you take on jobs outside Lisburn?
Yes. We also work in Belfast and Newtownabbey and elsewhere in County Antrim.
Is loft work in Lisburn different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
What do I need to do before you arrive in Lisburn?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Is loft boarding included in VAT relief?
No. Boarding is not an energy-saving material, so it is standard-rated if VAT applies, while the insulation underneath can be zero-rated.
Can you board the whole loft?
We can, but we usually advise boarding only what you need. Every boarded area costs more and makes later checks under the floor harder.
