What the job covers
- In England and Wales, Building Regulations apply when more than half of a wall is treated
- Internal insulation suits single rooms or where the outside can't change
- Solid walls can lose heat roughly twice as fast as an insulated cavity wall
- Breathable options for stone and lime-mortared walls
What we look for in Chatham
As well as Chatham itself, we quote in Rochester, Gillingham and Strood. It's roughly 8 miles from Chatham to Maidstone, the largest town in Kent. 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.
Much of Kent 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 Chatham homeowners weighing external against internal insulation, the survey sets out both with prices.

England: planning and regulations
For a house in Chatham, 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.
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 does solid wall insulation cost?
External systems run at roughly £105–£210 per m² of wall depending on the board and finish. Internal insulation is roughly £75–£130 per m², plus the cost of moving radiators, sockets and kitchen units.

Solid wall insulation in Chatham: questions
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.
Can I get a grant for solid wall insulation?
Some schemes cover it for eligible households — for example ECO4 until 31 December 2026, Home Energy Scotland's grant and loan, Wales' Warm Homes Nest and NI's Affordable Warmth Scheme. Each has its own eligibility and installer rules; see our grants guide.
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Do you cover Chatham?
Yes — we survey and quote solid wall insulation in Chatham (ME4) and nearby Rochester, Gillingham and Strood, with a fixed written price before any work starts.
