Converting commercial buildings such as offices or shops into homes is a well-established strategy in the UK. Because a building in the middle of a conversion usually cannot be financed on a standard mortgage, short-term bridging is often used to fund the purchase and, in some cases, the works.
In short: Change of use bridging finance funds the purchase or conversion of a building from one use to another, most commonly commercial to residential. Lenders look closely at the planning position, the cost and scope of works, the borrower’s experience and the end value.
Permitted development or full planning?
In England, some changes from commercial, business and service use to residential can be made under permitted development rights, through a prior approval process rather than a full planning application. Other conversions need full planning permission. Rules, exclusions and conditions apply, and they differ across the UK nations, so the planning route should be confirmed with the local authority or a planning consultant.
How is a conversion financed?
- Purchase bridge: buy the building, often before or during the planning process.
- Bridge with works: the purchase plus staged funding released as the works progress, usually after monitoring surveyor checks.
- Exit: sale of the finished units, or a refinance onto residential investment finance or development exit finance.
What do lenders look at?
Lenders typically review the planning consent or prior approval, building regulations sign-off plans, a schedule of works with realistic costings, the contractor and professional team, and comparable evidence for the finished units. Our refurbishment bridging guide covers how staged drawdowns work.
