A second charge bridging loan allows you to borrow against the equity in a property that already has a mortgage — without remortgaging or disturbing the existing loan. It's one of the most practical tools in property finance for investors who have built equity in their portfolio but don't want to break existing fixed-rate deals or trigger early repayment charges. This guide explains exactly how second charge bridging works, when it makes sense, and what it costs.
When a lender takes a charge over a property, they are registering a legal interest that gives them the right to be repaid from the property proceeds if the borrower defaults. The charge position — first or second — determines the order of repayment:
In practice, for a property with significant equity, the second charge position is very well protected — the property would have to fall dramatically in value before the second charge lender suffered a loss. This is why second charge bridging is widely available and actively funded by specialist lenders.
If your mortgage is in a fixed-rate period, breaking it to remortgage triggers an ERC — often 1%–5% of the outstanding balance. On a £400,000 mortgage, a 2% ERC is £8,000. A second charge bridge avoids this entirely. You leave the existing mortgage untouched and access the equity separately.
If you secured a low fixed rate before rates rose, remortgaging would mean giving it up for a much higher rate on the full balance. A second charge bridge lets you access new funds at a higher rate on the new borrowing only, preserving the low rate on the existing balance.
A full remortgage takes 4–8 weeks. A second charge bridge can complete in 1–3 weeks (allowing for first mortgagee consent). For time-sensitive opportunities, the second charge route is faster.
If your employment status, income, or credit profile has changed since your existing mortgage was arranged, remortgaging to a new lender might be difficult or more expensive. The second charge bridge doesn't require the existing lender to reassess your full mortgage.
Second charge lenders look at the combined LTV — the total of all debt secured against the property relative to its value:
Combined LTV = (First Charge Balance + Second Charge Loan) ÷ Property Value
| Item | Example |
|---|---|
| Property value | £600,000 |
| Existing mortgage (first charge) | £220,000 (37% LTV) |
| Available equity at 75% combined LTV | £450,000 − £220,000 = £230,000 |
| Second charge bridging loan | Up to £230,000 |
| Combined LTV | 75% (£450,000 / £600,000) |
Before a second charge can be registered, the first charge lender (your mortgage provider) must formally consent. This is called first mortgagee consent or prior ranking consent. Most mainstream lenders give this routinely — they are simply acknowledging the new charge, not assessing the new loan itself.
The consent process typically takes 2–4 weeks. This is the main reason second charge bridges take slightly longer to complete than first charge loans. Some specialist mortgage lenders (particularly in the buy-to-let market) have faster consent processes. Your broker should factor this timeline into the application process.
💡 Tip: Start the first mortgagee consent process as early as possible — in parallel with valuation and legal work. Delays in consent are the most common reason second charge bridges take longer than expected.
| Loan Type | Combined LTV | Typical Rate |
|---|---|---|
| First charge bridge (residential) | Up to 75% | 0.55%–0.90%/month |
| Second charge bridge (residential) | Up to 75% combined | 0.75%–1.10%/month |
| Second charge bridge (commercial) | Up to 65% combined | 0.90%–1.25%/month |
The rate premium for second charge versus first charge is typically 0.10%–0.25%/month. On a £200,000 six-month bridge, that's roughly £1,200–£3,000 in additional interest — often far less than the ERC cost of breaking the existing mortgage.
