Solid wall insulation · Edinburgh and the Lothians
Solid wall insulation in Edinburgh
From Edinburgh to Musselburgh, we price solid wall insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. For Edinburgh homeowners weighing external against internal insulation, the survey sets out both with prices.

What you get
- Internal insulation suits single rooms or where the outside can't change
- Solid walls can lose heat roughly twice as fast as an insulated cavity wall
- External insulation keeps room sizes and treats cold bridges well
- Both can be done in stages, elevation by elevation or room by room
Edinburgh: walls, weather and approvals
We also cover Musselburgh and Kirkcaldy, close to Edinburgh. East Central Scotland mixes stone tenements and terraces with post-war council housing and harled bungalows and semis.
Exposure to wind-driven rain varies across Edinburgh and the Lothians: 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 Edinburgh, we check wall thickness and age first to confirm there's no cavity to fill.

Planning and building control in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Edinburgh we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Scotland's building standards cover changes to external wall construction; we check whether your job in Edinburgh needs a warrant.
How can I tell if my walls are solid?
Measure the wall thickness at a window or door: about 225mm (9 inches) of brick usually means solid, while 260mm or more often means a cavity. On exposed brick, a pattern with bricks laid end-on (headers) every few courses points to solid construction. Stone walls are usually solid regardless of thickness. Age is a strong clue too — most homes built before the 1920s are solid-walled.

Solid wall insulation in Edinburgh: questions
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
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.
Do you cover Edinburgh?
Yes — we survey and quote solid wall insulation in Edinburgh (EH1) and nearby Musselburgh, Kirkcaldy and Dunfermline, with a fixed written price before any work starts.
