Morden: walls, weather and approvals
As well as Morden itself, we quote in Mitcham, Wimbledon and Carshalton. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London 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.
Freeholders and managing agents in Morden get a written specification and pricing they can share with owners.

Permissions in England
For a house in Morden, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
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.
What fire-safety rules apply?
For blocks with a storey 11 metres or more above ground, guidance points to external wall materials of limited combustibility, and combustible materials are banned in the external walls of relevant buildings 18 metres and over in England. Higher-risk buildings (18 metres or seven storeys and above, with at least two homes) go through the Building Safety Regulator. We specify non-combustible systems wherever these apply and tell you at enquiry stage if a building is outside our scope.

Flats and blocks in Morden: questions
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.
Who pays for EWI on a leasehold block?
In England and Wales, usually the leaseholders through the service charge, depending on the lease, and the landlord must follow the Section 20 consultation process for major works.
Do you cover Morden?
Yes — we survey and quote EWI for flats and blocks in Morden (SM4) and nearby Mitcham, Wimbledon and Carshalton, with a fixed written price before any work starts.
