Criterion 1: Are You a Homeowner With a Mortgage?
The first and non-negotiable requirement for a secured loan is that you are a homeowner with a property on which the lender can register a charge. You do not need to own the property outright — in fact, most secured loans are second charges placed behind an existing first charge mortgage. What you must not be is a tenant or a shared owner whose lease terms preclude a further charge (though some shared ownership arrangements do permit secured loans in certain circumstances).
The property must be your main residence or a residential investment property in the UK. Second charge lending on commercial properties is a separate specialist market. For buy-to-let properties, a smaller number of lenders offer second charge products, and the underwriting approach — particularly around rental income assessment and licencing requirements — is different from residential secured lending.
You must be a legal owner of the property — that is, you must be registered on the title at the Land Registry. If you live in a property but are not on the title (for example, a cohabiting partner of the legal owner), you cannot use that property as security for a secured loan in your own name. The security can only be granted by the legal owner or owners of the property.
Criterion 2: Do You Have Sufficient Equity?
Equity is the difference between your property value and the total of all loans currently secured against it. Secured loan lenders will advance funds up to a maximum combined loan-to-value (CLTV) — typically 80–85% across both the first mortgage and the proposed secured loan. The more equity you have, the more you can borrow and the lower the rate available.
To estimate your available equity, you need to know: your property's current market value (not the purchase price, but what it would sell for today); the outstanding balance on your first charge mortgage; and any other secured debt already on the property. Subtracting these from the property value gives you your current equity. Applying the lender's CLTV cap to the property value and then deducting the first mortgage balance tells you the maximum secured loan available.
For example, if your property is worth £300,000, your first mortgage balance is £150,000, and the lender caps at 80% CLTV, the maximum total secured debt is £240,000. Subtracting the £150,000 first mortgage leaves £90,000 as the maximum secured loan. At 85% CLTV the figure would be £105,000. Different lenders have different CLTV caps, and some specialist lenders — particularly for adverse credit cases — may cap at 70% or 75%.
