Included as standard
- Solid walls can lose heat roughly twice as fast as an insulated cavity wall
- Both can be done in stages, elevation by elevation or room by room
- In England and Wales, Building Regulations apply when more than half of a wall is treated
- External insulation keeps room sizes and treats cold bridges well

What we look for in Banbury
We also cover Bicester and Daventry, close to Banbury. Banbury is about 22 miles from Oxford. 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 Oxfordshire 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 Banbury homeowners weighing external against internal insulation, the survey sets out both with prices.

Planning and building control in England
Planning in Banbury 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 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 Banbury: questions
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.
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 do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Do you cover Banbury?
Yes — we survey and quote solid wall insulation in Banbury (OX16) and nearby Bicester, Daventry and Leamington Spa, with a fixed written price before any work starts.
