Before we quote in Swanley
As well as Swanley itself, we quote in Bexley, Dartford and Chislehurst. Swanley sits around 17 miles from Maidstone. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Kent sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
We compare EPS against mineral wool for each Swanley enquiry rather than assuming one board suits every wall.

England: planning and regulations
Before quoting in Swanley, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
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 Swanley: questions
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.
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.
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.
