What we look for in Eastbourne
We cover Eastbourne and nearby Seaford, Bexhill-on-Sea and Hastings. Eastbourne is about 19 miles from Brighton. 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.
Exposure to wind-driven rain varies across East Sussex: 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 a property in Eastbourne is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

England: planning and regulations
Planning isn't usually involved with internal insulation. Building control is, once more than half of a wall is treated, and listed buildings need listed building consent.
What are the risks with internal insulation?
Insulating inside makes the masonry colder, so moisture risk rises. Weak points are where floor joists bear into the wall, window reveals and corners. A condensation risk check for the build-up, a continuous vapour control layer where specified, and returning insulation into reveals deal with most of it.
