The housing market in the UK can be a difficult thing to navigate, but there are a few ways to increase the value of your home before evaluation.
Some of these changes might be more involved and cost more money than others, but should offer benefits down the line.
A few home improvement specialists have offered their advice on what to add to a home to improve its value.
All price elevations are calculated based on the average England property price according to the ONS, which as of February 2025 (most recent data), is £292,000.
How to add £100k plus to your property before evaluation
Spot renovations (£9,000)
Low-cost fixes to draughts, surfaces, doorways and windows can help add a small boost to your property's value.
Fixing up the bathroom, especially when it comes to improving your grouting, tiling, and mould, can also help.
Josh Jinks, Brand Manager at UltraTile, explains: "Prospective homeowners don't want to feel like they might have to deal with damp or failed grouting - left unattended, that can create a much bigger job further down the line, so using reliable waterproofing and tanking kits will be vital.
Basic spot renovations can add up to 3.1% sale value on a property, which works out at £9,052 for the average-priced home.
Boost kerb appeal (£14,600)
Cleaning up your property's exterior can offer some benefits, as it will provide the first impression for buyers.
Kevin Brown, aluminium windows renovation specialist from The Heritage Window Company, says: 'Timber windows, most noticeable in older properties, are particularly prone to weather damage over time and will be in dire need of cleaning, glazing and or repainting.
'Don't forget the driveway, either. Block paving in driveways will likely require a good pressure wash, cleaning away the moss, algae and grime build-up of the past few years."
In total, a well-maintained property exterior can add 5-7% value to a home, resulting in a minimum average of £14,600 value-added.
Increase bedroom storage (£29,200)
Improved storage space, and bedroom storage in particular, can add significant value to your home, according to Greg Carlisle from The Sliding Door Wardrobe Company.
He explains: 'Fitted bedroom wardrobes can increase property value by 10%, as well as help to sell a property quicker once it reaches market.
"If you go into any newbuild property in 2025, you'll find some sort of fitted storage solution, whether that's a walk-in wardrobe, understairs storage or integrated cupboards – and this added value is exactly why.'
With a potential added value of up to 10%, you can expect fitted bedroom storage to add up to £29,200 to your home.
Improve your EPC rating (£8,760–£57,232)
Improving the energy efficiency certificate attributed to your home will likely be the most costly investment, but should reap rewards.
This could include fitting double-glazing (or secondary glazing for older properties affected by planning permission) or draught-proofing the loft.
Kevin Brown explains: 'Upgrading your property from a D to a C rating costs £5,500 on average, resulting in added value of 3% or £8760.
"A more dramatic upgrade, from G to C for example, can see increased value as high as 19.6% or £57,232.'

Improve your garden (£58,000+)
Gardens add incredible value to your home through substantial but relatively low-cost changes.
Chris Cooper, lawn specialist at Hayter, explains: 'A well-maintained and landscaped garden can add up to 20% to your home, dramatically improving the final evaluation.
"To achieve a well-sculpted look quickly, you must start by making sure your lawn is neatly cut, weeded and well-presented with a planted border.
'Make sure you leave a minimum of one-third of your grass height to keep the lawn healthy, and in summer, make sure to mow every 1-1.5 weeks if the weather is especially warm."
