Using a bridging loan to buy business premises

A bridging loan to buy business premises is short-term finance that lets a trading business complete the purchase of the building it will occupy, then repay the bridge by refinancing onto an owner-occupier commercial mortgage once the timing pressure has passed. It is used when the seller, an auction or a lease event will not wait for a bank's full process.

This page is for owner-occupiers: companies buying the shop, office, workshop, clinic or warehouse they trade from. We explain when bridging makes sense, how the two-stage plan works, what the refinance lender will look for, and the regulated point if the building includes living accommodation you or your family will use.

Key takeaways
  • A bridge lets an owner-occupier complete on premises quickly, then refinance onto a commercial mortgage.
  • Plan the refinance before you buy: it is assessed on business affordability and accounts.
  • Mortgage LTV can be lower than bridging LTV, so plan for any equity gap.
  • If you or your family will live in part of the building, the loan may be regulated, so we introduce it to an FCA-authorised firm.
  • Where there is time and the accounts are strong, going straight to a mortgage is usually cheaper.

Why use a bridge to buy your business premises?

A commercial mortgage for an owner-occupier is usually the lowest-cost long-term way to own your premises, but it is not always the fastest. Banks will want two or three years of accounts, management figures, a full valuation and credit committee sign-off. That process can take longer than a seller will allow.

Owner-occupiers typically turn to bridging finance when:

For wider business uses such as cash flow or tax bills, see business bridging loans. If you are buying at auction, read auction bridging finance before you bid.

How does the bridge then refinance plan work?

The plan has two stages, and both should be mapped before you commit to the purchase.

  1. Bridge to complete. The bridging lender values the premises and lends against them, often within a few weeks where valuation and legal work move quickly. You fund the deposit, stamp duty and costs.
  2. Refinance to own. Once the business can present its accounts, the owner-occupier mortgage is applied for. The new lender repays the bridge, and you move onto a longer term with monthly capital and interest payments.

We look at the refinance at the outset, not at the end. If the business will not meet a mortgage lender's affordability test, the bridge has no exit and we will say so. Our guide covers the difference between a commercial bridge and a commercial mortgage in more depth, and the bridge vs mortgage calculator compares the costs.

What will the owner-occupier mortgage lender look for?

The bridge is only as good as the refinance behind it. Owner-occupier commercial mortgages are underwritten on the business, not just the building.

A common surprise is that the mortgage lender lends a lower percentage than the bridge. If that happens, the gap has to be found from cash or other security, so plan for it from day one.

What happens if the premises include a flat you will live in?

Many shops, pubs and small mixed buildings come with a flat above. If you, or an immediate family member, will live in the flat, the loan may be a regulated mortgage contract. We introduce any case like that to a firm directly authorised by the Financial Conduct Authority, so the right checks are made. We are not directly authorised by the Financial Conduct Authority ourselves.

If the flat is let to an unconnected tenant, or used only for business purposes, the bridge is usually unregulated and we arrange it directly. Lender appetite for semi-commercial premises also depends on the split between the commercial and residential parts. Our semi-commercial bridging loans page explains this, and the regulated vs unregulated guide sets out where the line falls.

Which entity should buy the premises?

Owner-occupiers usually choose between three structures:

Bridging lenders can lend to any of these, but the refinance lender may have preferences, particularly where a property company leases to a connected trading company. The right structure depends on your tax, legal and succession position. Take advice from your accountant and solicitor before you exchange. Our guide to bridging for limited companies covers the lending side.

What does it cost to buy premises with bridging finance?

Budget for both stages, not just the bridge:

Keeping the bridge term short is the most effective way to control cost. Where the business can afford it, serviced interest avoids interest compounding on the balance. See our rates page for how pricing is set and use the bridging cost calculator for your figures.

When should you go straight to a commercial mortgage instead?

If the seller will give you eight to twelve weeks, your accounts are filed and strong, and the premises are in good order, a direct owner-occupier mortgage is usually cheaper. Bridging adds a second set of fees and a period of higher interest. We will tell you if waiting for the mortgage is the better route, and our alternatives to bridging guide covers other options such as delayed completion or vendor finance.

For longer-term finance on this type of property, see our sister site Commercial Mortgages Broker.

Unregulated commercial and investment bridging is arranged directly. Any case where the security includes a home you or an immediate family member occupies, including a flat above commercial premises, may be regulated and is introduced to a firm directly authorised by the Financial Conduct Authority. We are not directly authorised by the Financial Conduct Authority ourselves. Your property may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

Good questions, clear answers

Buying business premises: questions answered

Ask about your situation
Can I use a bridging loan to buy the building my business rents?

Yes. This is one of the most common uses. If your landlord offers you the building with a short deadline, a bridge lets you complete, stop paying rent and then refinance onto an owner-occupier commercial mortgage. The refinance lender will often take the rent you were paying into account when looking at affordability, which can help your case.

How long does it take to arrange a bridge for business premises?

Where the title is clean and the valuation and legal work move quickly, a commercial bridge can complete in two to four weeks. Leasehold premises, complicated titles and slow replies from the seller's solicitor add time. The refinance onto a commercial mortgage usually takes longer, which is why the bridge term is set to allow for it.

How much deposit do I need to buy business premises with a bridge?

Bridging lenders commonly lend up to 70% to 75% of value on standard commercial premises, so expect to fund at least the balance plus stamp duty, fees and legal costs. The owner-occupier mortgage that follows may lend a lower percentage, so you should plan for any equity gap at the refinance stage as well.

Can a new business use a bridge to buy premises?

A bridging lender can lend to a new business because it focuses on the property and exit. The difficulty is the exit: owner-occupier mortgage lenders usually want accounts. Without trading history, the refinance may need to wait, or the property may need to be held in a structure that a lender can assess on rental income instead. We look at this before you commit.

Is a bridging loan for business premises regulated?

A bridge for a business buying premises it will trade from is usually unregulated, and we arrange it directly. If you or an immediate family member will live in part of the property, such as a flat above a shop, it may be a regulated mortgage contract. We are not directly authorised by the Financial Conduct Authority, so we introduce those cases to a firm that is.

Can I buy business premises through my pension with bridging?

Some pension schemes can buy commercial property, but borrowing by pension schemes is restricted and lender appetite is narrow. The scheme trustees, your pension administrator and your financial adviser need to be involved from the start. We can discuss whether bridging fits, but take advice from your pension provider and accountant first.
