Buying a Wimpey No-Fines house: survey and mortgage checklist
Wimpey No-Fines houses are not PRC, but they are non-standard enough that buyers should check lender appetite, wall condition, render, cracking and thermal performance before committing. This guide is the purchase checklist; the linked decoder page covers the construction explanation.

Wimpey No-Fines houses use in-situ no-fines concrete external walls, usually rendered externally and plastered internally. Many are ex-council or estate-built, with later insulation, render and window upgrades. Mortgageability is often better than PRC, but lender criteria and survey detail still matter.
Common defects to expect
These items are routine for the property type. Most are renegotiation items, not deal-breakers. The survey's job is to flag which apply to this specific property and which have already been addressed.
- Vertical cracking in no-fines concrete walls or external render
- Render spalling, hollow render or water ingress at cracks
- Poor thermal performance and low EPC without insulation upgrades
- External wall insulation poorly detailed around openings
- Condensation and mould from cold external walls
- Lender requesting structural engineer comment on concrete condition
- Asbestos in garages, soffits or later internal finishes
- Extensions built with different materials causing movement junctions
What the survey should cover
- Confirmation that the property is Wimpey No-Fines, not PRC or another concrete system
- Wall cracking pattern, render condition and whether cracks are active
- External wall insulation, if present, including fixing and detailing
- Damp, condensation and thermal-bridging evidence
- Roof, windows and services as with any post-war property
- Lender requirements for engineer report or valuation conditions
Which survey level to book
RICS Level 3 is recommended, with structural engineer input if cracking, render failure or lender conditions appear. Level 2 is too light where the construction type is the main purchase question.
For a deeper comparison see Level 2 vs Level 3 survey.
Construction-specific risks
The risk is usually not a PRC-style certificate problem; it is condition, lender comfort and thermal performance. Cracking and render defects should be inspected in the context of in-situ concrete, while EPC upgrades need compatible detailing so water is not trapped in the wall.
What to check before offering
- →Tell your broker the property is Wimpey No-Fines before applying
- →Ask whether previous sales needed an engineer report
- →Inspect render cracks and staining on every elevation
- →Read the EPC and check whether insulation upgrades are internal, external or absent
- →Ask for paperwork for external wall insulation, render replacement or structural repairs

Is Wimpey No-Fines the same as PRC?
No. It is an in-situ concrete system, not the same as designated defective PRC. Lender appetite is usually less binary than PRC, but it is still non-standard construction and should be disclosed early to the broker.
What survey should I get for a Wimpey No-Fines house?
Level 3 is the safer choice, with engineer input if there are wall cracks, render failure or lender conditions. The survey should confirm the system and assess wall, render and thermal-performance issues.
Are Wimpey No-Fines houses hard to mortgage?
Many lenders will consider them with a satisfactory survey, but not every lender treats them the same. Confirm lender appetite before paying for detailed surveys and searches.
Where should I read the full construction explanation?
