Remortgaging to Release Equity: How It Works and What It Costs

1 Step 1

Remortgaging to release equity means replacing your current mortgage with a larger one and taking the difference as a tax-free cash lump sum. The cash comes from the equity you have already built in your home. Done for the right reason, it is one of the cheapest ways to borrow a large amount. The new, bigger loan still has to be affordable, and it remains secured against your property.

This guide explains exactly how it works, how much you can release, what it costs in June 2026, and the situations where it makes sense versus the situations where it quietly costs you money. We are a whole-of-market broker, so this is the honest version, not a sales pitch for one lender’s product.

What does remortgaging to release equity mean?

Equity is the share of your home you actually own. It is the current market value of the property minus the amount you still owe on your mortgage. If your home is worth 350,000 pounds and you owe 150,000 pounds, you have 200,000 pounds of equity.

When you remortgage to release equity, you take out a new mortgage that is larger than your current balance. Your new lender pays off the old loan, and the extra amount is paid into your bank account. You are not getting free money. You are borrowing against your home, and you repay it over the term of the new mortgage.

This is different from a standard remortgage, where you simply switch to a new deal for the same balance to get a better rate. Here you are deliberately increasing the loan to free up cash. Lenders call this capital raising.

How much equity can you release?

The amount you can release is capped by your loan-to-value, or LTV. That is the size of your mortgage as a percentage of your property value. Most residential lenders will go up to 85 percent LTV for capital raising, and some up to 90 percent, although the rate gets more expensive the higher you go.

Here is the maths on the example above:

Property value: 350,000 pounds
Maximum borrowing at 85 percent LTV: 297,500 pounds
Existing mortgage to clear: 150,000 pounds
Maximum equity you could release: 147,500 pounds

That is the theoretical ceiling. In practice the figure is usually lower, because the loan also has to pass the lender’s affordability and stress tests. Releasing equity does not mean a lender will hand over the maximum simply because the equity exists. They assess whether you can comfortably repay the larger loan.

How does remortgaging to release equity work?

The process is almost identical to a normal remortgage, with one extra layer of scrutiny on why you want the extra money and whether you can afford it.

You confirm your property value and current mortgage balance, then work out the equity available.
Your broker checks the whole market for a lender that accepts your reason for raising the money at the LTV you need.
You apply, providing income evidence, bank statements and details of the purpose of the funds.
The lender runs an affordability assessment and stress test, then instructs a valuation.
Once the mortgage offer is issued, a solicitor handles the legal transfer.
The new lender clears your old mortgage and the released equity is paid to you.

A remortgage to release equity usually takes four to eight weeks from application to completion. Self-employed cases or higher LTV applications can sit at the longer end of that range because underwriting is more detailed. If you want the practical timeline for the legal stage, the same conveyancing steps apply as a normal purchase.

What can you use released equity for?

Lenders care about the purpose because it affects risk. Some reasons are widely accepted and priced normally. Others restrict your lender choice or your maximum LTV. The strongest uses tend to be ones that add value or improve your overall financial position.

Commonly accepted reasons include:

Home improvements such as an extension, a new kitchen or a loft conversion, which can also increase the property value.
Raising a deposit for a second home or a buy-to-let property.
Consolidating expensive unsecured debt, where the sums genuinely add up after fees and the longer term are accounted for.
Gifting a deposit to help a child onto the ladder.
Covering a large one-off cost such as a divorce settlement or a tax bill.

Reasons that lenders scrutinise more heavily, or sometimes decline, include investing in a business, buying cryptocurrency or shares, paying for ongoing day-to-day spending, or settling gambling debts. None of these are automatically refused, but they narrow the field, and that is exactly where whole-of-market advice earns its keep.

A word on debt consolidation

Rolling a credit card or a personal loan into your mortgage can lower your monthly outgoings, because mortgage rates are far cheaper than card rates. The trap is the term. Spreading a five-year debt over a 20-year mortgage can mean you pay more interest overall, even at a lower rate, and you turn unsecured debt into debt secured against your home. It can be the right move; it is not automatically the right move. Run the total cost, not just the monthly figure.

What does it cost in 2026?

The cost of releasing equity is the interest on the extra borrowing, plus any fees, plus an early repayment charge if you leave your current deal early. As of June 2026, the Bank of England base rate is 3.75 percent, held at that level since December 2025. The next decision is on 18 June 2026 and is widely expected to be another hold, although some economists see a small chance of a rise later in the year.

Average fixed rates in June 2026 sit at around 5.68 percent for a two-year fix and 5.63 percent for a five-year fix. The best deals are sharper at lower LTV: roughly 4.35 percent on a two-year fix at 60 percent LTV, and around 4.48 percent to 4.54 percent on the best five-year fixes. Push the LTV up towards 85 percent and pricing rises into the high fives. By contrast, the average standard variable rate is about 7.13 percent, which is why slipping onto your lender’s SVR is almost always the most expensive outcome.

Here is what the extra borrowing actually costs each month. Say you release 40,000 pounds and add it to a repayment mortgage at 4.6 percent over 20 years:

Extra borrowing: 40,000 pounds
Added monthly payment: roughly 255 pounds
Total repaid on that 40,000 pounds over 20 years: roughly 61,300 pounds
Interest cost of the release: roughly 21,300 pounds

That total interest figure is the number most people never see, because they only look at the monthly cost. Borrowing against your home is cheap per month and expensive over a long term. Where you can, take equity over the shortest term you can afford, or overpay later to cut the interest.

Watch the early repayment charge too. If you are still inside a fixed deal, leaving early can trigger a charge of one to five percent of the balance. Often the sensible move is to time the equity release for the point when your fixed rate ends, or to raise the money through a further advance with your existing lender instead.

Remortgage to release equity, further advance, or equity release: what is the difference?

These three terms get muddled constantly, and the difference matters.

Remortgaging to release equity means moving to a new lender and increasing the loan. Best when a new lender offers a better overall deal on the larger balance.
A further advance means borrowing more from your current lender on top of your existing mortgage, usually on a separate rate. Best when you are mid-deal and an early repayment charge would make switching pointless.
Equity release is a specific later-life product, normally a lifetime mortgage for homeowners aged 55 and over, where no monthly payments are required and the interest rolls up. It is a different product with different advice rules and is not the same as a capital-raising remortgage.

If you are under 55 and working, you almost certainly want a remortgage or a further advance, not a lifetime mortgage. Choosing between a switch and a product transfer or a remortgage comes down to your current deal, the early repayment charge, and how much the better rate elsewhere actually saves you.

Who can release equity? Lender criteria in 2026

You will need enough equity, a clean enough credit profile, and provable income that supports the larger loan. The decisive factor is affordability. Lenders stress-test the new, higher payment against a notional rate, typically in the region of 7 to 8.5 percent, to check you could still cope if rates climbed.

Key points lenders look at:

Your income and how stable it is. This is where the how much you can borrow question gets answered properly.
The purpose of the funds, as covered above.
Your age and the mortgage term, since the loan must usually be repaid before a set age.
Your credit history and any recent missed payments.

If you are self-employed, expect more detailed underwriting. Lenders want two to three years of accounts or tax calculations, and they differ widely on how they treat retained profit and a falling latest year. A self-employed remortgage to release equity is entirely doable, but lender choice is narrower, which is exactly when a broker who knows the criteria saves you wasted applications.

Is remortgaging to release equity a good idea?

It is a good idea when the money does something productive: improving the home, securing an asset that should grow, or replacing genuinely more expensive borrowing. It is a poor idea when it funds short-term spending you will be repaying for two decades, or when it pushes your LTV so high that the rate becomes punishing.

The honest test is simple. Will the thing you are buying with the equity still be paying you back, in value or in saved interest, by the time you have finished repaying it? If yes, it is usually sound. If no, think again.

Frequently asked questions

Is the money released from equity tax-free?

Yes. Releasing equity by remortgaging is borrowing, not income, so there is no income tax to pay on the cash. Tax can arise later depending on what you do with the money, for example capital gains tax if you use it to buy an investment property that you later sell at a profit.

How much equity can I release from my home?

Typically up to 85 percent of your property value, occasionally 90 percent, minus your existing mortgage. The final figure depends on the lender’s affordability assessment, your income, your age and the purpose of the funds, so the amount you qualify for is often less than the LTV ceiling alone suggests.

Does releasing equity increase my monthly payments?

Usually, yes. A larger loan over the same term means a higher monthly payment. The increase can be offset if you also secure a much lower interest rate at the same time, but in most cases your payment rises in line with the extra borrowing.

Can I release equity if I am still in a fixed-rate deal?

You can, but leaving a fixed deal early may trigger an early repayment charge of one to five percent of the balance. In that situation a further advance from your current lender, or waiting until your fixed term ends, is often cheaper than remortgaging away.

How long does it take to release equity by remortgaging?

Generally four to eight weeks from application to the funds reaching your account. Straightforward employed cases at lower LTV move faster; self-employed or higher LTV cases take longer because underwriting is more involved.

Can I release equity if I am self-employed?

Yes. You will typically need two to three years of accounts or HMRC tax calculations, and lenders vary in how they assess your income. Fewer lenders means it pays to use a broker who knows which ones suit your figures.
