Bridging Loans for Barn Conversions

You can get a bridging loan to buy a barn with consent to convert, or to fund early works, at lower loan-to-values than finished homes. The exit is usually a self-build mortgage, development finance, a mortgage on the finished home, or a sale.

An unconverted barn is not a habitable home, so standard mortgage lenders will not lend on it. Bridging, self-build mortgages or development finance fund the purchase and conversion until the finished home can be mortgaged.

Class Q is a permitted development right in England allowing agricultural buildings to be converted into homes without full planning permission, subject to prior approval from the council on matters such as access, flood risk and design.

In England, from 21 May 2024, Class Q allows up to 10 homes within 1,000 square metres of total floorspace, with no home over 150 square metres, and permits a single-storey rear extension of up to 4 metres on existing hardstanding.

Class Q does not allow a rebuild: the building must be structurally capable of conversion, with only works reasonably necessary for the conversion. Lenders usually ask for a structural report confirming this.

A barn conversion needs either Class Q prior approval, where the building and scheme qualify, or full planning permission. Larger, non-agricultural or listed buildings usually need full planning permission. The planning route is confirmed before buying.

Some lenders bridge barns without consent at low loan-to-values, but the value and exit depend on obtaining Class Q prior approval or planning, so the risk is higher and choice narrower.

Lenders usually require a structural report confirming the barn can be converted without rebuilding, because both the consent and the value depend on it. It also identifies costs that affect the budget.

Some bridging lenders fund works in stages, but most barn conversions are funded by a self-build mortgage or development finance after the bridge secures the purchase. The bridge is then repaid from that longer-term finance.

Self-build mortgages can fund barn conversions, releasing money in stages as the work progresses, and can refinance a bridge used to buy the barn. The barn must have consent and be structurally suitable.

Development finance suits barn conversions built for sale, particularly multi-unit Class Q schemes, while a self-build mortgage suits one home to live in. A bridge can secure the purchase first.

Barns can be converted into holiday lets with suitable consent, financed on completion by a holiday-let mortgage on projected letting income. Some Class Q and planning consents restrict use, which is checked first.

Barn conversions commonly take many months to over a year, depending on structure, services and access. The bridge term is set to cover the time to arrange conversion finance, not the whole build.

You can offer your existing home as additional security, often as a second charge, to increase the loan or reduce the cash needed. Because you live there, that part of the bridge is regulated.

A genuinely non-residential barn bought for £200,000 in England or Northern Ireland attracts £1,000 SDLT under the non-residential bands. Classification depends on the facts; a barn within a dwelling’s grounds may be treated differently. Wales and Scotland have separate land taxes.

Converting a non-residential building into a home can qualify for a reduced rate of Value Added Tax (VAT) on eligible building work, and self-builders may reclaim VAT on materials under the do-it-yourself (DIY) housebuilders scheme. An adviser confirms eligibility.

Barn conversions often exceed budget because of structural repairs, bringing services to remote sites, access works, insulation and drainage. A substantial contingency protects the exit. Set the contingency using the survey findings and costed work schedule.

Mortgage lenders on a converted barn usually require a structural warranty or an architect's certificate of practical completion, so arranging one from the start keeps the mortgage exit open. Retrofitting a warranty later is difficult.

The usual exits are a self-build mortgage or development finance taking over during the conversion, a residential or holiday-let mortgage on completion, or the sale of the finished home. The exit is evidenced before the bridge completes.

A barn bridge may be regulated where the security is intended to become your home, even before you move in. The borrower, land use and any business-lending exclusion need checking; taking security over your current home also brings its occupation into the assessment.
