Timber-framed properties are often treated as non-standard construction — though most lenders class modern timber frame with a brick or block outer skin as standard — and a large portion of the lending market, including some high-street names, will mortgage them on standard terms. The work lies in reading the valuer's evidence correctly and placing the case with a lender that understands the construction type.
What counts as timber frame construction
Most UK housing stock is brick and block. A timber-framed property is built around a structural frame of timber — the wood is the base of the house. The category spans centuries: post-and-beam period properties where exposed oak carries the load, and modern open-panel and closed-panel systems where the frame sits behind conventional cladding.
The distinction matters to lenders. In a modern home, exposed beams are usually aesthetic rather than load-bearing, and the structure is straightforward to assess and to repair. In an older property the frame itself is the structure; if its integrity cannot be established, the lender is carrying the risk that its security deteriorates. That is why a minority of lenders decline timber frame altogether — and why most, properly evidenced, do not.
How lenders assess a timber-framed property
Everything turns on the valuer's comments. A timber-framed property in good order will generally proceed on standard products at standard pricing. Where the valuer notes disrepair, a full damp and timber report is required to confirm structural integrity before the lender commits.
Closed-panel construction deserves particular attention because the frame is hidden — defects are not always obvious to the owner, let alone a buyer. The valuer's checks, together with when the property was built, where it sits and how much timber is in it, determine what further evidence the lender asks for.
Condition and location both feed into leverage. A property needing significant refurbishment may carry a loan-to-value cap or a retention until works are complete, and properties in very low-value areas can be restricted on saleability grounds — the lender's concern being how readily the asset would sell if it ever had to.
Who this is for
- Investors and portfolio landlords buying or refinancing timber-framed stock, whether held personally or through a limited company.
- Owners of period timber-framed properties remortgaging, raising capital or restructuring borrowing against a listed or historic home.
- Buyers of modern timber-framed houses, including new-build closed-panel construction, who want the case placed with a lender comfortable from the outset.
Loan-to-value and deposit
On residential property, high loan-to-value options are available subject to lender and condition. For buy-to-let, around 75% loan-to-value is fairly standard, which means a deposit of 25% to 30%.
The construction type itself rarely moves these numbers; condition does. A house in generally poor repair may see its loan-to-value capped in both residential and buy-to-let, or funds retained until specified works are done. Rates move with the market — we quote against your actual case.
What it costs
The mortgage product is the same as on standard construction. The rate, the lender arrangement fee, the valuation, the legal work and the broker fee all sit where they otherwise would — there is no timber-frame premium built into the pricing.
The variable is what happens after valuation. If the valuer calls for further inspection — damp and timber reports, roofing reports, or asbestos reports on some older properties — those are at your cost. Expect a few hundred pounds per report in the worst case, varying with the size of the property and how quickly it is needed. It will not break the budget on a transaction of any scale, but it should be priced in from the start.
How the process works
- Construction review. We establish the frame type, age and condition before any lender is approached, so the case is presented to institutions that will actually lend on it.
- Lender selection. The property profile is matched against the panel — high street where the case is clean, specialist where the frame, the tenure or the borrower structure demands it.
- Application. From your side this is a standard mortgage application: proof of income on residential, rental evidence on buy-to-let, company structure where relevant.
- Valuation and reports. The valuer inspects; any further reports are commissioned promptly so the underwrite is not held up.
- Offer and completion. Once the lender is satisfied on the structure, the case completes as any other would.
Is it difficult to get a mortgage on a timber-framed house?
No — securing a mortgage on a timber frame property is relatively straightforward. It comes down to the valuer's comments. If the property is in a state of disrepair, a proper damp and timber report is needed to confirm structural integrity; assuming that is fine, plenty of lenders will proceed and the products will be fairly standard. The point is knowing which banks to approach first.
Can I get a buy-to-let mortgage on a timber-framed property?
Yes. You will need a 25% to 30% deposit and a decision on whether to hold the property personally or through a limited company. The application itself is fairly standard — the construction type simply changes which lender we use in the background.
Are mortgages on timber-framed homes more expensive?
Not in the product. Where the property is in reasonable condition, the rate and fees match what an equivalent borrower would pay on brick and block. The additional cost, where there is one, comes from post-valuation reports — typically a few hundred pounds each where the valuer requests them.
Why do some lenders decline timber-framed properties?
Risk on the security. In older properties where the frame is load-bearing, overall structural integrity can be hard to determine — and a lender holding a charge over a property that fails structurally holds a charge over very little. Some institutions exclude the category for that reason. A large portion of the market takes a more measured view, lending where the survey evidence supports it.
Where does a broker add value on a timber construction case?
In the pairing. A timber-framed security is one variable; complex income, a portfolio structure or a limited company vehicle is another. The broker's role is to put the combination in front of the lender that accepts all of it — so you end up with the right institution, the right product, and a price that reflects the case rather than the construction label.
