What the job covers
- Internal insulation suits single rooms or where the outside can't change
- In England and Wales, Building Regulations apply when more than half of a wall is treated
- Solid walls can lose heat roughly twice as fast as an insulated cavity wall
- External insulation keeps room sizes and treats cold bridges well

Lancaster: walls, weather and approvals
We also cover Morecambe and Fleetwood, close to Lancaster. Lancaster is about 20 miles from Preston. The North West has one of the largest stocks of pre-1919 solid-wall terraces in England, alongside Pennine stone houses and post-war estates.
Parts of Lancashire fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
For Lancaster homeowners weighing external against internal insulation, the survey sets out both with prices.

Permissions in England
Planning in Lancaster 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.
What does solid wall insulation cost?

Solid wall insulation in Lancaster: questions
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Does solid wall insulation cause condensation?
It can if detailed poorly, particularly internally. A condensation risk check for the proposed build-up and careful detailing at joists, reveals and corners avoid it.
Is solid wall insulation worth it?
For many solid-walled homes it's one of the biggest single improvements to comfort, because the walls are often the largest heat-loss area. Savings depend on the home and heating, so we don't promise a figure.
