How a second charge works
When a property is mortgaged, the lender registers a charge against the title at HM Land Registry. A second charge bridge adds another charge behind it. If the property is sold, the first lender is repaid in full before the second receives anything.
You keep your existing mortgage, its rate and its terms. That is the main appeal: if you have a low fixed rate or would face early repayment charges, a second charge avoids refinancing the whole debt to raise a smaller amount. You can check what is registered against a property through HM Land Registry.
Common uses
- Raising a deposit for another purchase, including auction deposits
- Funding works on another property
- Releasing equity quickly for a business purpose
- Supporting a chain break where the existing mortgage stays in place until the sale
- Settling a tax bill or other liability while a longer-term plan is arranged
As with any bridge, the lender will want a clear exit, such as the sale of a property or a refinance of both charges.
Combined loan to value and pricing
Second charge lenders look at the combined borrowing: the first mortgage balance plus the new loan, as a percentage of value. Limits are lower than for first charges, often in the region of 65% to 70% combined, depending on the lender and property.
Pricing is higher than for a comparable first charge bridge, because the second lender takes more risk. Fees follow the usual pattern of arrangement, valuation and legal costs. See bridging loan fees.
Consent from the first lender
Many first charge lenders require their consent before a second charge is registered, and some, particularly on buy-to-let and commercial mortgages, will refuse it. Residential mortgages for homes are treated differently, and second charges on them are generally possible without consent, though the first lender is notified.
The consent process can add time, so it is worth checking your mortgage terms early. If consent is refused, the alternatives include a first charge bridge that repays the existing mortgage, or taking security over a different property.
Regulation
If the property is, or will be, lived in by you or a close family member, the loan is a regulated mortgage contract and comes with additional protections. We will tell you at the outset if that applies and how your case will be handled.
Your home or property may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it. Instant Quotes can show second charge options: compare them on Instant Quotes.
Alternatives to a second charge
A second charge is not the only way to raise money against property that already has a mortgage. Depending on your circumstances, alternatives include:
- A first charge bridge that repays the existing mortgage and raises the extra funds in one loan, often at a lower rate but with the cost of redeeming the mortgage
- A further advance from your existing mortgage lender, which can be cheaper but is usually slower
- Taking security over a different property that is unencumbered or has more equity
- A remortgage, if time allows and the property qualifies
The right choice depends on early repayment charges on the existing mortgage, how quickly you need the funds and how long you need them for. Comparing the total cost of each route, including fees and any redemption penalties, usually makes the answer clear.
Common questions
Do I need my mortgage lender's permission for a second charge?
Often, for buy-to-let and commercial mortgages. For residential mortgages on your home, consent is generally not required, but the first lender is notified.
How much can I borrow on a second charge bridge?
It depends on the combined loan to value across both charges. Limits are commonly lower than for first charge bridging.
Why is second charge bridging more expensive?
The second lender is repaid only after the first mortgage, so it carries more risk and prices accordingly.
