What is different about insulating a flat's loft?
In most leasehold flats the loft belongs to the freeholder, so the managing agent or freeholder must agree to the work. Shared lofts usually have fire separation between flats that must not be disturbed. More about loft insulation for a flat.

Why book with us in Ruthin
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.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
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 loft insulation for a flat cost in Ruthin?
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).

Questions about loft insulation for a flat in Ruthin
Can a landlord in Ruthin book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
What do I need to do before you arrive in Ruthin?
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 work in Ruthin 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 I insulate the loft above my flat?
Usually yes, with the freeholder's consent. The lease will say who owns and maintains the roof space.
Is there VAT on loft insulation in flats?
Flats are residential, so installing insulation is zero-rated until 31 March 2027.
