Barnet: walls, weather and approvals
Surveys in Barnet also cover the surrounding EN5 district and towns such as Potters Bar and Borehamwood. 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.
For Barnet properties, the survey also confirms whether planning or building control is needed for your address.

Planning and building control in England
Planning in Barnet 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
What do I get afterwards?
A written quote listing the system (board, thickness and finish), the detailing included, scaffolding, any repairs found, exclusions, the VAT treatment and the expected programme. Where planning or building control is needed, the quote says so and who handles it.

Do I need to be home?

How long is the quote valid?
The quote states its validity period, usually 30 days, because material prices change.
How long does the survey take?
Usually 45–90 minutes for a house. Blocks and commercial buildings take longer.
