Local considerations in Orkney, Shetland and the Western Isles
The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Orkney, Shetland and the Western Isles fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.

Scotland: planning and regulations
In Scotland, householder permitted development rights are set by the Scottish GPDO and are narrower for external wall changes; insulating flats or tenements, changing the appearance of a house noticeably, or working in a conservation area usually needs planning permission. Listed buildings need listed building consent. Ask your council's planning team before committing.
Work that alters an external wall's construction is covered by the building standards system; many over-cladding projects need a building warrant from the council's building standards team, and Section 6 (Energy) of the Technical Handbooks sets insulation benchmarks.
What is EPS insulation?
Expanded polystyrene is a closed-cell foam made from beads that are expanded and moulded into boards. White EPS is the standard grade; grey EPS has graphite added, which reflects radiant heat and improves performance by roughly 15–20%, so a thinner board does the same job. Both are used inside certified render systems where the board, adhesive, fixings, mesh and finish are tested together by the manufacturer.

EPS insulation in Orkney, Shetland and the Western Isles: questions
White or grey EPS?
Grey graphite EPS insulates better per millimetre, so it is the pick where space is tight at the eaves or around windows. White EPS is slightly cheaper and works well where the extra thickness isn't a problem.
How long does EPS last on a wall?
The board itself doesn't degrade when protected by the render system. Service life depends on the render, sealants and detailing, typically 25–30 years or more with maintenance.
Will woodpeckers damage EPS?
It happens occasionally, especially near woodland. Damage is to the render and board surface and is repaired with a mesh patch and colour-matched finish.
Do you cover all of Orkney, Shetland and the Western Isles?
Yes. We survey and quote EPS external wall insulation across Orkney, Shetland and the Western Isles, including Kirkwall, Stornoway, Lerwick. Island and remote addresses are surveyed by arrangement.
Do I need planning permission in Scotland?
In Scotland, householder permitted development rights are set by the Scottish GPDO and are narrower for external wall changes; insulating flats or tenements, changing the appearance of a house noticeably, or working in a conservation area usually needs planning permission. We check your address before quoting.
