External wall insulation cost per m² in Edinburgh
External wall insulation by property type in Edinburgh
The UK figures are current property examples; the city column applies the same moderated 18% regional weighting as the live calculator.

Current UK system benchmarks
What can change a real Edinburgh quote?
- External wall area
- EPS, mineral wool or board system
- Render or cladding finish
- Scaffolding
- Gutter and pipework changes
- Existing wall condition
Local planning considerations
Property type, access and conservation constraints can materially change individual quotations beyond the regional model.
- Check conservation, listed-building and traditional-material requirements before assuming standard external alteration costs.
- Upper-floor and tenement projects can require extra access, common-property coordination or scaffold planning.
- Use Scotland-specific regulatory and grant information for compliance or energy projects rather than assuming Great Britain rules are identical.
How the regional model works
The live external-wall-insulation calculator uses only 18% of the broad Scotland regional difference because insulation boards, fixings and render systems contain a substantial nationally priced material component. The resulting Edinburgh EWI factor is 0.991× and is applied to the current £150–£200 per m² installed benchmark.

Frequently asked questions
How much does external wall insulation cost in Edinburgh in 2026?
The current UK installed benchmark is £150–£200 per m², averaging about £175 per m². Using the same moderated regional factor as the live calculator gives a Edinburgh planning rate of about £149–£198 per m².
How much is external wall insulation for a semi-detached house in Edinburgh?
The current UK semi-detached example is £14,000–£20,000, averaging £17,000. Applying the moderated Edinburgh model gives about £13,850–£19,800, with a modelled midpoint near £16,850.
Why is the Edinburgh EWI adjustment smaller than the broad regional factor?
External wall insulation contains a large material and system component, so the live calculator applies only 18% of the broad regional difference rather than treating the entire installed price as locally variable labour.
What can make external wall insulation more expensive?
Wall repairs, scaffolding, architectural detailing, moving rainwater pipes and services, premium finishes, difficult access and larger exposed wall areas can all increase the final quote.
