If you want a treadmill to help with your fitness goals but don't want to spend a fortune, there are plenty of solid options for under £500. A home treadmill is one of the easiest ways to improve your health and fitness from your own living room, and you don't need a gym-grade budget to get a machine that lasts.
Over the past few years the number of treadmills on the high street and online has exploded, but only a handful are genuinely worth buying. Below are the best treadmills under £500 we'd recommend, ranked, with the specs, speeds and trade-offs that actually matter so you can pick the right one with confidence.
The Bluefin Fitness KICK 2.0 is our top pick of treadmills under £500. This compact machine balances quality features with versatility, packing in gym-level extras including a top speed of 12 km/h (around 7.5 mph), a generous 18% incline to burn extra calories, and 16 training programs that suit beginners and experienced runners alike.
It's very quiet in use, so you can train without disturbing family or neighbours, and the bright LCD display gives a clear overview of distance, speed, time and heart rate. The built-in speakers are Bluetooth compatible, so you can connect your phone and listen to music while you run.
| Top speed | 12 km/h |
|---|---|
| Incline | 18% |
| Max user weight | 120 kg |
| Programs | 16 |
| Folding | Yes |

The large running area is comfortable underfoot and easy on the joints thanks to the shock-absorption technology. A common frustration with home treadmills is keeping the belt lubricated, but the KICK 2.0 has a self-lubricating system that only needs the occasional drop of oil into an accessible pipe to keep things running smoothly.
It's also compatible with the Kinomap fitness app, which offers a huge range of coaching videos, live classes and other workouts. Connect your phone or tablet, pop it on the holder and you can take your sessions further. The treadmill ships with a wireless heart rate chest strap that pairs with the LCD screen automatically for accurate live data. When you're done, it folds up to save space and the transport wheels make it easy to move with no heavy lifting.

The max user weight is 120 kg (around 19 stone).

When buying a home treadmill, it pays to stick with established brands. A well-known name usually means better build quality that won't fail after a few weeks, and the bigger brands typically include a warranty so you can get any faults fixed free of charge.
Brands we'd recommend include JLL, Dripex, Viavito, Bluefin and Sportstech. Machines from these makers are vetted by us and tend to come with features such as adjustable incline, a useful range of speeds, a large running track, a clear console and built-in workouts.
Each treadmill has its own strengths and weaknesses, so pick one that fits your priorities. If price matters most, go for a budget model; if storage or a quiet motor is more important, weigh that up first. Decide which feature matters most to you before you buy.
