Your home is likely your largest financial asset. Once you have built up equity, there are several ways to benefit from it: equity release, strategic home improvements, renting out a room, or simply selling at the right time. Each option carries different costs and risks, so it is worth understanding them before committing.
Short Summary
Equity is the portion of your property's value that you own outright. It grows as you pay down your mortgage and as house prices rise. For example, if your home is worth £300,000 and your outstanding mortgage is £100,000, your equity is £200,000.
Equity release allows homeowners aged 55 or over to access some of that equity as cash, without selling. The most common product is a lifetime mortgage, regulated by the Financial Conduct Authority (FCA).
Home improvements can add value, but not all projects deliver a return. Extensions and loft conversions tend to add the most; cosmetic changes rarely recover their full cost at resale.
Renting out a room under the government's Rent a Room scheme lets you earn up to £7,500 per year tax-free. This can be one of the simplest ways to generate income from your home.
How does equity build up in your home?
Equity increases in two ways. First, each monthly capital repayment reduces your outstanding mortgage balance. Second, if the market value of your property rises, your equity grows automatically even without making extra payments.
Over a typical 25-year mortgage, the proportion of your payment that goes towards capital (rather than interest) increases over time. In the early years, the majority of your monthly payment covers interest. By the final years, most of the payment is reducing the actual debt.
According to the Land Registry, UK average house prices have roughly doubled over the past 20 years, though regional variation is significant. London and the South East have seen larger gains than parts of the North and Midlands.
What is equity release and how does it work?
Equity release lets homeowners aged 55 or over borrow against the value of their home without selling it. The most widely used product is a lifetime mortgage, where you take a lump sum or drawdown facility and interest rolls up over time. The loan, plus accumulated interest, is repaid from the sale of the property when you die or move into long-term care.
The Equity Release Council, the industry body, requires all its members to include a no negative equity guarantee, meaning you or your estate will never owe more than the property is worth.
Equity release is not right for everyone. It reduces the inheritance you leave, and interest compounds over many years. The Money Helper service (run by the Money and Pensions Service) strongly recommends taking independent financial advice before proceeding.
| Equity release product | How it works | Who it suits |
|---|---|---|
| Lifetime mortgage | Borrow against your home; interest rolls up; repaid on death or care | Most over-55 homeowners |
| Home reversion plan | Sell a share of your home to a provider; continue living there rent-free | Older homeowners wanting maximum cash |
| Retirement interest-only mortgage | Monthly interest payments required; loan repaid on death or care | Those who can afford monthly payments |
Which home improvements add the most value?
Not every home improvement adds value, and many cost more than they add to the sale price. Projects that typically deliver the best return are those that add usable space or bring a property up to local market standards.
According to research by Nationwide, a loft conversion that adds a bedroom can increase property value by up to 20 per cent. A kitchen or bathroom renovation adds value if the existing one is dated, but over-specifying a kitchen in a modest property rarely pays off.
| Improvement | Potential value added | Typical cost |
|---|---|---|
| Loft conversion (bedroom) | Up to 20% | £20,000 to £50,000 |
| Single-storey extension | Up to 15% | £15,000 to £40,000 |
| New kitchen (mid-range) | 5 to 10% | £8,000 to £20,000 |
| New bathroom | 3 to 5% | £4,000 to £10,000 |
| New windows/doors | 2 to 4% | £5,000 to £12,000 |
Always check whether planning permission is required before starting any significant work.
Can I earn money by renting out a room?
Yes. The government's Rent a Room scheme lets you earn up to £7,500 per year from renting out a furnished room in your main home, completely tax-free. You do not need to declare this income if it is below the threshold.
If your rental income exceeds £7,500, you pay tax only on the amount above the threshold. You must notify HMRC if you earn more than the allowance. Check the current rules on GOV.UK as the threshold can change.
Before renting out a room, inform your mortgage lender and your home insurance provider, as both may have conditions or require policy amendments.
What are the risks of using your home to generate profit?
Using your home as a financial asset carries real risks. If property values fall, your equity can shrink or disappear. Equity release compounds interest over many years, so what seems like a modest borrowing today can become a much larger debt by the time it is repaid.
Home improvements funded by further borrowing increase the mortgage balance. If you cannot sell at a price that covers your costs, you could end up with less equity than before.
For any significant decision involving your home's equity, seek advice from a qualified adviser who is authorised by the FCA. The Equity Release Council's website lists approved advisers.
FAQ
At what age can I access equity release?
The minimum age for most equity release products is 55. Some providers set the minimum at 60. Both owners must meet the age requirement if the property is jointly owned.
Does equity release affect my state pension or benefits?
It can. A lump sum from equity release may affect means-tested benefits such as Pension Credit or Council Tax Reduction. Before proceeding, check the impact with a benefits adviser or use the GOV.UK benefits calculator.
Is it better to downsize or use equity release?
Downsizing involves selling your current home and buying a smaller, cheaper property. It usually releases more cash and avoids the interest that rolls up on a lifetime mortgage. Equity release may suit those who want to stay in their home. A financial adviser can model both options for your specific circumstances.
Do home improvements require planning permission?
Minor internal changes and most single-storey rear extensions under a certain size are covered by permitted development rights and do not require planning permission. Larger extensions, loft conversions with a dormer, and changes to a listed building or property in a conservation area usually do require permission. Check with your local planning authority before starting work.
Can I remortgage to fund home improvements?
Yes. If you have sufficient equity, you can remortgage to a higher loan amount and use the extra funds for improvements. This is called a further advance or capital raising remortgage. The additional borrowing is secured against your home, so make sure the monthly repayments are affordable before proceeding.
