Why book with us in Ballycastle
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
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.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
How much does a loft insulation top-up cost in Ballycastle?
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).
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 a loft insulation top-up in Ballycastle
How do I pay for work in Ballycastle?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Will I get a written quote for work in Ballycastle?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Is loft work in Ballycastle 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.
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.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
