Capital raising: how to borrow against your home

Capital raising means borrowing more against a property you already own, taking the extra as cash. There are three routes: remortgage to a new lender for a larger amount, take a further advance from your current lender, or add a second charge loan behind your existing mortgage. Which is cheapest depends on your current rate, any early repayment charge, and how much you need — the answer differs case by case.

What does capital raising mean?

Answer first: borrowing more against a property you already own, and taking the extra as cash. If your home is worth more than you owe on it — through repayments, rising prices, or both — that gap is equity, and capital raising is how you turn part of it into money you can use.

People do it to fund home improvements, to raise a deposit for another property, to invest in a business, or to consolidate expensive debt. For contractors and company directors, investing in the business is a particularly common driver — and, at the right lender, a perfectly acceptable one.

The three routes

Remortgage to a new lender. You move your whole mortgage to a new lender for a larger amount. The new lender pays off the old one and advances the extra. This opens the whole market and applies one new rate to the entire balance — often the cheapest route if your current deal has ended.

Further advance from your current lender. You keep your existing mortgage untouched and borrow extra from the same lender, usually on its own rate and term. This is the route when your current deal is good and you don’t want to disturb it. The full comparison is in remortgage vs further advance.

Second charge loan. A separate loan secured on the property, sitting behind your existing mortgage — which keeps its priority as the first charge. Like a further advance, it leaves your main mortgage alone, but it comes from a different lender, which widens your options if your own lender won’t lend the extra.

When does a second charge make sense?

Two situations, mainly.

Your current rate is too good to lose. If you’re on a low fixed rate, remortgaging the whole balance onto today’s rates to release a modest sum can be a bad trade — you’d be repricing your entire mortgage to raise a fraction of it. A second charge leaves the good rate intact and prices only the new money.

You’re locked in by an early repayment charge. If leaving your current deal mid-term would trigger a substantial early repayment charge, that cost can easily exceed the benefit of remortgaging. A second charge sidesteps it entirely.

The trade-off is rate: second charge rates are typically higher than mainstream mortgage rates. So the honest comparison isn’t “which has the lower rate” — it’s total cost, weighing a higher rate on a small sum against a higher rate on your whole balance plus any penalty.

What will lenders let you raise money for?

They will ask, and the answer matters. Commonly accepted purposes include home improvements, a deposit for another property, debt consolidation, and investing in your business. These are seen as sensible, value-adding or wealth-neutral.

Lenders are more cautious about speculative purposes, and some will decline them. Business investment sits in the middle: many lenders accept it, but criteria vary and some are notably more comfortable than others — which is exactly where knowing the market pays. Being clear and realistic about the purpose, and choosing a lender comfortable with it, is part of getting the raise approved.

How much can you raise?

Three limits apply: your property’s value, the lender’s maximum loan-to-value, and your affordability. The first two set a ceiling; affordability usually sets the real limit.

For a contractor, affordability is the swing factor — and it’s where lender choice changes the answer. A lender that annualises your gross day rate through contract-based underwriting can support a substantially larger raise than one reading the minimised profit on your accounts. The same equity, the same property, a very different result. Model the effect on your monthly payment with the remortgage calculator before deciding how much to take.

A word of caution

You’re converting an asset into debt secured on your home, usually over a long period. That’s fine when the purpose justifies it — adding lasting value, acquiring another asset, or replacing costlier borrowing. It’s much less fine when it funds ongoing spending, because you’re stretching a short-term cost across a long-term secured loan.

And if the purpose is consolidating debt, read debt consolidation remortgage first: lowering the monthly payment while increasing the total cost is an easy trap, and the home is what secures it.

The bottom line

Capital raising turns equity into cash through one of three routes — remortgage, further advance, or second charge. A second charge protects a good existing rate or avoids an early repayment charge, at the cost of a higher rate on the new money. Compare total cost across all three rather than the headline rate of any one. For contractors, the lender that reads your day rate properly is also the one that lets you raise the most. To compare the routes on your figures, speak to an adviser.

Think carefully before securing other debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it.
