Bridging Loan for a Self-Build

You can use a bridging loan for a self-build to buy a plot quickly, release equity from your current home to fund the build, or finish a stalled project. A self-build mortgage, a mortgage on the finished home or a sale repays it.

A bridge is faster to arrange and can fund needs a self-build mortgage does not, such as securing a plot before approval or covering a shortfall. Self-build mortgages are usually cheaper for the build itself, so the two are often combined.

You can buy a building plot with a bridging loan, at a lower loan-to-value than a finished home. A plot with planning permission is easier to bridge than one without, and the exit is usually a self-build mortgage.

Bridging lenders lend a lower percentage against land than against homes, and lower still without planning permission. Using your existing home as security instead, often as a second charge, can support a larger loan for the plot.

Some lenders bridge land without planning permission at low loan-to-values, but the exit is uncertain until planning is granted. Most self-builders buy plots with planning, or with an option conditional on planning.

A £150,000 plot attracts no SDLT if it qualifies as non-residential land in England or Northern Ireland. Bare land is not automatically non-residential: existing garden or grounds and buildings under construction can change the treatment. Scotland and Wales use different land taxes.

You can use your existing home as security for a bridge — often as a second charge behind your mortgage — to buy a plot, which can support a larger loan than the plot alone. Because you live there, the bridge is regulated.

A bridge secured on your current home can release equity to fund the plot and early build stages, letting you stay put until the new home is finished. The sale of your old home then repays the bridge.

You do not have to sell first: a bridge on your current home, or a self-build mortgage alongside your existing mortgage if affordable, can fund the project, with the old home sold on completion.

A self-build mortgage funds the purchase of a plot and the build in stages, released as each stage is completed and inspected, either after the stage (arrears) or before it (advance). It converts to a standard mortgage on completion.

A bridge secured on the part-built home, or on other property, can fund the work needed to finish a stalled self-build. The exit is usually a residential mortgage on the completed, warranted home.

Self-builds commonly run over budget because of ground conditions, design changes, material and labour cost rises, and delays. A costed contingency and staged funding reduce the risk of needing extra finance.

Mortgage lenders on a completed self-build usually require a structural warranty or an architect's certificate of practical completion, so arranging one from the start of the build keeps the refinance exit open.

The Community Infrastructure Levy (CIL) self-build exemption lets eligible self-builders avoid the levy on their home, but it must be claimed and confirmed by the council before work starts, and the home occupied as the main residence for a set period.

Under HM Revenue and Customs' (HMRC) do-it-yourself (DIY) housebuilders scheme, you can reclaim Value Added Tax (VAT) on eligible materials for a new home you build to live in, with the claim made within six months of completion.

Self-build bridges commonly run for up to 12 to 24 months, matched to the time needed to arrange the self-build mortgage, complete the build or sell the old home. Longer builds suit staged self-build mortgages rather than bridging alone.

A self-build bridge is regulated if secured on a home you or a related person live in, such as your current home. A plot intended for your own home can also fall within regulation. Classification must account for intended use, not only whether a building is occupied today.

Lenders accept a self-build mortgage agreed in principle, a residential mortgage on the finished home with a warranty, or the sale of your existing home. The exit is evidenced before the bridge completes.

Self-build lenders are cautious with adverse credit because of the build risk, but some specialist lenders consider it, particularly with a larger deposit. The bridge and the exit must both accept the credit history.

Development finance suits larger or multi-unit schemes built for sale, while a self-build mortgage suits one home to live in. A bridge fills gaps in either, such as securing land before the main finance is approved.
