What's included
- 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
- Both can be done in stages, elevation by elevation or room by room
What we look for in Ipswich
Surveys in Ipswich also cover the surrounding IP1 district and towns such as Harwich and Felixstowe. The East of England has a mix of post-war estates, inter-war semis and older solid brick and flint cottages, with some system-built council homes on post-war estates.
Much of Suffolk 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 Ipswich homeowners weighing external against internal insulation, the survey sets out both with prices.

Approvals in England
Planning in Ipswich 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.
How can I tell if my walls are solid?
Measure the wall thickness at a window or door: about 225mm (9 inches) of brick usually means solid, while 260mm or more often means a cavity. On exposed brick, a pattern with bricks laid end-on (headers) every few courses points to solid construction. Stone walls are usually solid regardless of thickness. Age is a strong clue too — most homes built before the 1920s are solid-walled.

Solid wall insulation in Ipswich: 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 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.
Do you cover Ipswich?
Yes — we survey and quote solid wall insulation in Ipswich (IP1) and nearby Harwich, Felixstowe and Stowmarket, with a fixed written price before any work starts.
