Quick summary

The home improvements that add the most value are knocking down walls to create open-plan spaces, which can add up to £48,000 in London, or building garden rooms that can boost your home's worth by around £36,000 in Surrey. A new kitchen, downstairs toilet, or ensuite can also significantly increase your property's value, often by £14,500 to £26,000. Generally, projects costing around £1,500 to £7,000 can deliver substantial returns, especially if they focus on long-term features like bi-fold doors or eco-friendly upgrades.

Before you invest in improving your home wouldn’t it be nice to know that the money you spend will be worth it, not just in terms of the enjoyment you’ll get from your new and improved space, but financially too. So, we’ve asked the property advice website HomeOwners Alliance which projects add the most value.

Working out your home’s current value

You’ve probably got a good idea of what home improvement project you want to do next. But before you start, it’s important to work out how much your property is worth now. Ask at least three local estate agents to visit and value your property. They’ll do this for free. And if you feel awkward because you aren’t planning to sell anytime soon, don’t worry. Estate agents are more than happy to meet potential future clients they can add to their books.
