Local considerations in Stockton-on-Tees
As well as Stockton-on-Tees itself, we quote in Billingham, Thornaby-on-Tees and Middlesbrough. It's roughly 10 miles from Stockton-on-Tees to Darlington, the largest town in County Durham. The North East has many solid brick terraces, including former colliery housing, plus post-war council estates with some system-built homes.
Exposure to wind-driven rain varies across County Durham: 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.
For terraced homes in Stockton-on-Tees with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

Planning and building control in England
Internal insulation rarely needs planning permission, but in England and Wales insulating or replastering more than half of a wall's area involves building control, and listed buildings need consent for internal changes that affect their character.
Do I need Building Regulations approval?
Yes, in England and Wales once you insulate or replaster more than half of a wall's area (or more than a quarter of the building's whole envelope), it's treated as renovating a thermal element. The wall should reach about 0.30 W/m²K where practical, and building control needs to be involved.
