Corby: walls, weather and approvals
We cover Corby and nearby Uppingham, Kettering and Market Harborough. Corby sits around 19 miles from Northampton. Housing in the East Midlands includes Victorian terraces in the towns and cities, plenty of inter-war semis and post-war council estates, some of them system-built.
Much of Northamptonshire 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.
On mixed-tenure blocks in Corby, we agree access and resident notices with the managing agent before scaffold goes up.

Approvals in England
Planning in Corby follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
Who needs to agree to EWI on a block?
The freeholder or management company commissions the work, but leaseholders usually pay through the service charge. In England and Wales, major works above the statutory threshold trigger the Section 20 consultation process before a contract is placed. We provide the specification and pricing you need for that consultation.

Flats and blocks in Corby: questions
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Do you work on high-rise buildings?
Tell us the height and number of storeys. Buildings in the higher-risk category have a separate regulatory route, and we'll say plainly if we're not the right contractor.
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Do you cover Corby?
Yes — we survey and quote EWI for flats and blocks in Corby (NN17) and nearby Uppingham, Kettering and Market Harborough, with a fixed written price before any work starts.
