What you get
- In England and Wales, Building Regulations apply when more than half of a wall is treated

- Internal insulation suits single rooms or where the outside can't change
- Both can be done in stages, elevation by elevation or room by room
Poole: walls, weather and approvals
We cover Poole and nearby Bournemouth, Christchurch and New Milton. Poole sits around 5 miles from Bournemouth. 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 solid-walled homes in Poole, we check wall thickness and age first to confirm there's no cavity to fill.

Permissions in England
Before quoting in Poole, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
What does solid wall insulation cost?
External systems run at roughly £105–£210 per m² of wall depending on the board and finish. Internal insulation is roughly £75–£130 per m², plus the cost of moving radiators, sockets and kitchen units.

Solid wall insulation in Poole: questions
Can I get a grant for solid wall insulation?
Some schemes cover it for eligible households — for example ECO4 until 31 December 2026, Home Energy Scotland's grant and loan, Wales' Warm Homes Nest and NI's Affordable Warmth Scheme. Each has its own eligibility and installer rules; see our grants guide.
Does solid wall insulation cause condensation?
It can if detailed poorly, particularly internally. A condensation risk check for the proposed build-up and careful detailing at joists, reveals and corners avoid it.
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Do you cover Poole?
Yes — we survey and quote solid wall insulation in Poole (BH15) and nearby Bournemouth, Christchurch and New Milton, with a fixed written price before any work starts.
