A lender name is only half the answer — the amount each might lend varies by tens of thousands — our figures are conservative estimates, not offers.
See your figuresWhy some lenders say no
- Some precast reinforced concrete (PRC) types are designated defective under the Housing Act 1985 — most lenders will only lend on these with an approved structural repair and a PRC certificate.
- The final decision almost always sits with the valuer: two identical construction types can get different answers depending on condition, location and how mortgageable comparable sales look.
- Resale risk drives the policy — lenders worry about how easily the property sells at repossession, so unusual types in areas with few comparables get declined even by flexible lenders.

Run My Affordability CheckFrequently asked questions
What counts as non-standard construction?
Anything that isn't brick or block walls with a tiled or slated pitched roof: concrete (poured or precast panel), steel-frame, timber-frame with non-brick cladding, cob, wattle-and-daub, flat-roofed properties and modern methods of construction (MMC). Timber-frame with a brick outer skin is treated as standard by most lenders.
Can I get a mortgage on a PRC house?
Usually only if it has been structurally repaired under an approved scheme, evidenced by a PRC certificate. Designated defective types (Airey, Unity, Woolaway, Cornish and similar) are declined without one by nearly every lender. With a valid certificate, a good number of high-street lenders will consider the property at normal rates.
Is Wimpey No-Fines concrete a problem?
Much less than precast panel types. Wimpey No-Fines and Laing Easiform are cast in situ, aren't designated defective, and most mainstream lenders accept them subject to the valuer confirming condition. You generally don't need a repair certificate for these.
Does non-standard construction affect how much I can borrow?
Affordability is calculated the same way, but some lenders cap LTV on non-standard types, which raises the deposit you need. It can also affect buildings insurance costs — worth checking quotes before you commit, because lenders require insurance to be in place from exchange.
