What is a bridging loan?
A bridging loan is short-term secured borrowing typically 1–24 months in duration, used to bridge a financial gap until permanent finance is in place. Common London uses: buying a renovation property at auction (cash required within 28 days), funding a renovation while waiting for planning permission or remortgage, financing a refurbish-to-sell project, or covering the gap between selling one property and buying another. Bridging is fast (funds can be released in 5–15 working days), but expensive (0.6–1.2% per month interest, plus 1.5–3% arrangement fees, plus broker fees of 1–2% and legal fees of 0.5–1%). Total all-in cost typically 12–18% per annum equivalent.
When bridging makes sense
Three scenarios where bridging is the right tool. First, time-critical purchase — auction properties require completion in 28 days, faster than any high-street mortgage can deliver. Bridging covers the purchase, renovation funds the value uplift, and a residential mortgage or sale exits the bridge within 6–12 months. Second, refurb-to-sell developer projects — small developers (£500k–£3m projects) use bridging to fund purchase plus refurbishment, exit through sale within 6–18 months. Third, planning-pending projects — buy a property without planning consent at lower price, use bridging to hold while obtaining planning, exit through remortgage at consented value. Bridging is rarely appropriate for owner-occupier renovations where time is not critical.
When NOT to use bridging
Three scenarios where bridging is the wrong tool. First, simple home improvements — a £75,000 extension on your owner-occupier home doesn't need bridging; use remortgage or further advance at half the cost. Second, no clear exit — bridging lenders require a defined exit strategy (sale, remortgage, refinance). Without one, you'll be unable to repay and could lose the property. Third, marginal projects — if the post-completion value barely covers the loan plus interest plus fees, the project is too thin for bridging's high cost; better to wait, save more equity, or scale back the project. Bridging amplifies returns but also amplifies losses.
Bridging loan costs in 2026
For a £500,000 bridging loan over 12 months. Interest at 0.9% per month: £54,000. Arrangement fee at 2%: £10,000. Broker fee at 1%: £5,000. Legal fees: £3,500. Valuation: £1,500. Exit fee at 1%: £5,000. Total cost over 12 months: £79,000 (15.8% of the loan). Compare to a remortgage: same £500k at 5% over 12 months = £25,000 interest plus £2,500 in fees, total £27,500 (5.5% of the loan). Bridging is roughly 3x the cost of a remortgage. The premium is justified only when speed, flexibility or risk profile makes a remortgage impossible or impractical.
How to arrange bridging finance
Bridging is broker-led; do not approach lenders directly. Use a specialist bridging broker like Y3S Bridging, Octopus, KSEYE or Brightstar. The broker assesses your case, matches to suitable lenders (United Trust Bank, Together, Octane, Glenhawk are major active lenders) and negotiates terms. Application typically requires: property valuation, exit strategy proof (planning application, sale particulars, mortgage agreement in principle), bank statements, business case if developer or refurb-to-let, and personal credit profile. Decision in 5–10 working days; funds released 5–15 working days after legal completion. Always pre-arrange your exit strategy in parallel — bridging lenders frequently extend at higher rates if you can't exit on time.
