Internal wall insulation in Poole
If you're planning internal wall insulation in Poole, start with a free survey: we measure, check the walls and confirm planning and building control for your address. Where a property in Poole is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Local considerations in Poole
As well as Poole itself, we quote in Bournemouth, Christchurch and New Milton. It's roughly 5 miles from Poole to Bournemouth, the largest town in Dorset. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Dorset: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For terraced homes in Poole with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

Approvals in England
Internal insulation rarely needs planning permission, but in England and Wales insulating or replastering more than half of a wall's area involves building control, and listed buildings need consent for internal changes that affect their character.
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 Poole: questions
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
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.
Do you cover Poole?
Yes — we survey and quote internal wall insulation in Poole (BH15) and nearby Bournemouth, Christchurch and New Milton, with a fixed written price before any work starts.
