Adding value to your home: what pays off and what doesn't

Some improvements make a home easier to sell and worth more. Others are lovely to live with but rarely get their money back. Before you spend, it's worth knowing which is which, and checking how much homes on your street can realistically sell for.
Know your street's ceiling price
Every street has a rough ceiling: the most anyone has paid for a home there. You can spend a lot improving a house, but if it ends up priced well above anything else that has sold nearby, buyers and lenders' valuers will be cautious. Look up your street and note the highest recent sales for homes like yours. If your plans would push your home far beyond that, you're less likely to recover the cost when you sell.
Improvements that usually add value
Extra space. Adding a bedroom, through a loft conversion or extension, is one of the most reliable ways to add value, especially in areas where families compete for homes. A well-designed kitchen extension that creates an open living space is also popular. Check whether you need planning permission or can use permitted development rights, and always get building regulations sign-off.
Off-street parking. In areas where parking is hard, a driveway can add noticeably to a home's value. You'll need a dropped kerb, which needs council approval, and possibly planning permission.
Energy efficiency. A better EPC rating means lower bills, and buyers and lenders increasingly pay attention to it. Loft and cavity wall insulation, modern heating controls and an efficient boiler or heat pump are good places to start. Check which grants are available first.
Fixing problems. Damp, a leaking roof, old wiring or a failing boiler put buyers off far more than the cost of fixing them. Sorting these first often gets you a better price and a smoother sale.
Improvements that rarely pay for themselves
- Swimming pools and hot tubs appeal to a small number of buyers and cost money to run.
- Expensive kitchens and bathrooms in a modest home. A tidy, modern kitchen helps a sale, but a top-of-the-range one rarely adds as much as it costs.
- Converting a garage where parking is scarce can reduce value.
- Very personal taste, such as bold colours or unusual layouts, may need undoing by a buyer.
Cheap things that help a sale
Fresh neutral paint, a tidy front garden, clean windows, fixed taps and handles, and good lighting all cost little and make the home feel cared for. Buyers often judge the whole house by the first thirty seconds.
Before you start
If you live in a conservation area or a listed building, many changes need extra consent. Check with your council before you commit to anything. Keep every certificate and guarantee, because the buyer's conveyancer will ask for them.
