A second charge bridging loan sits behind an existing mortgage on a property. The first charge lender — your mortgage lender — takes priority on enforcement; the bridging lender takes second position. What that means in practice: you can access equity in a mortgaged property quickly without refinancing or touching the existing deal. For more on second charge bridging as a product, the dedicated product page covers the basics.

This article goes a level deeper: when second charge bridging is the right tool, how the consent process actually works, what rates look like compared with first charge, what the full cost adds up to, and what lenders are assessing before they agree to sit in second position.

First Charge vs Second Charge — What the Difference Means in Practice

When a lender takes a first charge over a property, they have first claim on the proceeds if it is ever sold or repossessed. A second charge lender sits behind that — they can only recover what is left after the first charge lender has been repaid in full.

For the borrower, the practical implications are three things:

The existing mortgage stays in place. You are not redeeming or refinancing. Your current rate, term and conditions are untouched. If you are on a fixed rate you want to keep, the second charge is the mechanism that lets you access equity without breaking it.
You need the first charge lender's consent. The mortgage lender must agree to a second charge being registered. Most mainstream lenders — high street banks, building societies — will provide consent as a matter of course if the combined LTV stays within their limits. Some specialist or adverse credit mortgage lenders may not. That needs confirming before the case is structured.
The second charge lender carries more risk. If enforcement is ever needed, they may not recover the full loan if there is insufficient equity after the first charge is repaid. This is why second charge bridging rates are priced at a small premium over an equivalent first charge case.

Second charges on non-primary-residence property are typically unregulated — see the regulated vs unregulated bridging article for the full distinction. Unregulated means the assessment focuses on the exit and the security, not on income affordability.

When Second Charge Bridging Is the Right Tool

Second charge bridging solves a specific problem: you need capital quickly, your property has equity, but you cannot or do not want to disturb the existing mortgage.

Preserving a low mortgage rate. A borrower on a fixed rate at 2.1% does not want to redeem and remortgage to access equity. A second charge bridge gets the capital without breaking the existing deal.
Speed requirements. A first charge remortgage typically takes 6–10 weeks. A second charge bridge can complete in 2–4 weeks — the consent process is faster than a full refinance.
Equity release for a purchase or project. A landlord or developer using equity in an existing property to fund a deposit on a new acquisition, or to cover refurbishment costs on another site, where the timeline does not allow for a remortgage.
The property is temporarily unmortgageable. A property that has been partially refurbished, or has a lease issue on a sub-unit, may not be remortgageable at acceptable terms. The existing mortgage stays; a second charge bridge funds the works.

Second charge bridging is also regularly the path for borrowers with adverse credit who cannot remortgage — see the adverse credit bridging article for how lenders approach that combination.

When it is not the right tool: if the combined LTV (first charge plus second charge) is high, the arithmetic may make a remortgage cheaper overall. And the consent process adds time — typically 5–10 working days for mainstream lenders. If that time is available, comparing total cost against a fast remortgage is worth doing before committing.

Second Charge Bridging Rates — What to Expect in 2026

Second charge bridging is priced at a small premium over equivalent first charge bridging, reflecting the additional recovery risk to the lender. The premium is typically 0.05–0.15% per month over a comparable first charge case with the same security, LTV and borrower profile.

Current indicative benchmarks from the panel:

Charge position	LTV (combined)	Indicative rate range
First charge	up to 70–75%	0.55–0.75% pm
Second charge	up to 65–70% combined	0.65–0.85% pm

These are indicative ranges only — actual placement depends on the security, the exit, the borrower's profile, and which lenders are competing on the case. LTV for second charge bridging is calculated on the combined loan-to-value: the outstanding first charge mortgage plus the bridging loan, divided by the property value. A property worth £500,000 with a £200,000 mortgage and a £100,000 second charge bridge gives a combined LTV of 60% — well within the range most lenders will consider.

The combined LTV ceiling for second charge bridging is typically 65–70%. Above 70%, the panel of willing lenders narrows significantly. For live rates by product: rates page.

The Consent Process — What Happens and How Long It Takes

Before a second charge can be registered, the first charge lender must be formally notified and must consent. The mechanics:

Consent letter requested. The second charge bridging lender or their solicitor writes to the first charge lender requesting consent to register a second charge.
First charge lender reviews. They check that the combined LTV remains within their own policy limits and that the borrower's account is not in arrears. For straightforward cases — clean payment history, combined LTV within limits — consent is typically returned within 5–10 working days.
Consent received. The second charge is registered at Land Registry and the loan can complete.

Implications for timing: build the consent turnaround into your timeline. A bridge that could otherwise complete in 10 days may take 20–25 days on a second charge case. Some lenders operate a policy of granting consent automatically up to a stated combined LTV — worth confirming with your mortgage provider before structuring the deal.

If the first charge lender declines consent — rare, but it happens with some specialist lenders and certain ex-local-authority lenders — the options are to redeem the first charge or to find alternative security for the bridge.

What a Second Charge Bridge Actually Costs

Worked example: £150,000 second charge bridge, on a property worth £450,000 with an existing £100,000 mortgage (combined LTV 56%), 6-month term, residential property, remortgage exit.

Cost item	Basis	Amount
Arrangement fee (1.5%)	1.5% × £150,000	£2,250
Interest (0.75% pm, retained, 6 months)	0.75% × £150,000 × 6	£6,750
RICS valuation	Estimate	£600
Second charge lender legal costs	Estimate	£1,500
Broker fee (1%)	1% × £150,000	£1,500
Total cost of borrowing		£12,600
Net advance (after retained items)	£150,000 − £2,250 − £6,750	£141,000

The consent process from the first charge lender does not usually carry a direct fee, but some lenders charge a small administration fee — typically £50–£200. Confirm this before proceeding. You can run the numbers on your own case using the calculator.
