Local considerations in Cheshire
The North West has one of the largest stocks of pre-1919 solid-wall terraces in England, alongside Pennine stone houses and post-war estates.
Exposure to wind-driven rain varies across Cheshire: 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.
Where eaves are shallow on a house in Cheshire, grey EPS can sometimes avoid the cost of extending the roofline.

Permissions in England
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
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 Cheshire: 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.
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.
Is EPS insulation safe on a house?
EPS is used inside render systems that are fire-tested as a whole. On low-rise houses it is widely used. On taller buildings, or where guidance calls for non-combustible materials, mineral wool systems are specified instead.
Do you cover all of Cheshire?
Yes. We survey and quote EPS external wall insulation across Cheshire, including Warrington, Chester, Crewe, Macclesfield, Runcorn.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
