Ranked by ROI

Best-ROI Home Improvements for 2026

ROI here means value added divided by cost. The cheapest presentation jobs top the table on a pure-percentage basis, while space-adding projects deliver the biggest cash gains where the street ceiling allows. The best strategy usually blends both.

Improvement	Typical ROI	Best for
Repaint & kerb appeal	200%+	Every home, before selling
Loft conversion	120–200%	Homes below the street ceiling
Kitchen refresh (doors/worktops)	130–180%	Dated but sound kitchens
Insulation & EPC quick wins	100–150%	Cold, lower-EPC homes
Single-storey extension	80–150%	Family homes with big ceiling gap

Compare against what adds the most value overall and see how uplift varies by region.

Reading the Table Right

Percentage ROI vs Cash Gain

Chase percentage on a budget

If cash is tight, the cheap presentation jobs win: they return the most per pound and improve the payback of everything else you do.

Chase cash gain with headroom

If your street ceiling is far above your value, a loft or extension adds the biggest absolute sum, even at a lower percentage.

Mind the ceiling

Any project that pushes you above the local ceiling sees its ROI collapse. The ceiling caps every row in the table.

Watch the running-cost story

In 2026, EPC and energy improvements are climbing the ROI table as buyers price in bills more heavily than before.

Frequently Asked Questions

Best ROI Home Improvement FAQs

Which home improvement has the best ROI in 2026?+

On a pure-percentage basis, cheap presentation work — repainting and kerb appeal — tops the table at 200%+ because it removes buyer objections for very little cost. For the biggest cash return, a loft conversion at 120–200% ROI usually wins where the street ceiling allows.

What does ROI mean for home improvements?+

ROI is the value added divided by the cost. A project costing 10,000 pounds that adds 15,000 pounds of value has a 150% ROI. It is the clearest way to compare improvements of different sizes, though it should always be read alongside the actual cash gain.

Do extensions have good ROI?+

Extensions can return 80–150% where there is a large gap between your home's value and the street ceiling, and where the new space creates a proper kitchen-diner or extra bedroom. On homes already near the ceiling, ROI falls sharply, so the local market matters more than the build itself.

Is insulation a good return on investment?+

Increasingly, yes. Loft and cavity insulation and draught-proofing are cheap, cut running costs and can nudge the EPC up a band. In 2026, with buyers focused on bills, energy-efficiency work is climbing the ROI table and often returns 100–150%.

Does a high-ROI project always mean a big profit?+

Not necessarily. A cheap job can have a huge percentage ROI but a small cash gain. To grow your home's value meaningfully you often need a larger project with a lower percentage but a bigger absolute return — so read ROI and cash gain together.

How do I calculate ROI before I start?+

Estimate the value uplift from local sold prices, get firm quotes for the work, then divide the uplift by the cost. Anything comfortably above 100% recovers its spend; below that, treat the project as lifestyle rather than investment.
