Homes and walls in Annan
As well as Annan itself, we quote in Dumfries, Hawick and Peebles. It's roughly 15 miles from Annan to Dumfries, the largest town in Dumfries and Galloway. South West Scotland has stone and harled houses, coastal towns and post-war council housing.
Parts of Dumfries and Galloway fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
We plan internal insulation in Annan homes room by room so you keep the rest of the house usable.

Scotland: planning and regulations
Internal insulation rarely needs planning permission; listed buildings need consent for internal changes.
Over-cladding work in Scotland often needs a building warrant from the council's building standards service, with Section 6 of the Technical Handbooks setting insulation benchmarks.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.

Internal wall insulation in Annan: questions
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
Do you cover Annan?
Yes — we survey and quote internal wall insulation in Annan (DG12) and nearby Dumfries, Hawick and Peebles, with a fixed written price before any work starts.
