External Wall Insulation in Edinburgh
EWI systems that insulate solid walls externally and finish them in a warranted render topcoat.
Edinburgh property owners come to us for external wall insulation for one of two reasons: something has failed, or the house looks tired.
Most of what we see around Edinburgh reflects the wider Midlothian pattern — Georgian and Victorian stone terraces, tenements and modern estates, and conservation lime work on Edinburgh stone and harling repair.
Local conditions bring cold easterly exposure with frequent frost, and that has a direct bearing on which systems are worth specifying. Edinburgh's world heritage core carries some of the strictest conservation requirements in britain, and only lime specifications will get consent.
When external wall insulation is the right call. Choose EWI on solid-wall, no-fines or non-traditional construction where you want a genuine thermal upgrade rather than just a new finish.

FAQs
External Wall Insulation in Edinburgh
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.
What areas do you cover?
We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
How much does external wall insulation save?
On a typical uninsulated solid-wall semi it commonly cuts wall heat loss substantially and makes the biggest single difference to comfort. Actual savings depend on the existing construction, heating system and how you use the house.
Do I need planning permission for EWI?
Often not on a standard house, but you will if it is listed, in a conservation area, or if it alters the appearance significantly. We advise before starting.
