Best Treadmill Under £400: 3 Top Picks for Home (2026)

If you're after the best treadmill under £400, the good news is that a budget like this stretches further than you'd think, though the options are surprisingly thin below this price point. After testing manual and motorised models for home use, we found three foldable treadmills that genuinely punch above their price: the Nero Sports, the Sunny Health & Fitness SF-T1407M, and the LONTEK P5.

Working from home punched a hole in our metabolism, and our old shirts suddenly stopped fitting. If you can relate, you're in the right place. All three machines below have a large running deck, useful speed levels and an incline, and every one folds away so it won't take over your spare room.

1. Nero Sports Foldable Electric Motorised Treadmill: Best Overall

Nero Sports makes it genuinely easy to get moving at home. It fits a modest budget, offers 12 workout programmes, and includes a phone or tablet holder at the front so you can stay entertained mid-session.

It's built around a robust 600W motor, about right for an at-home treadmill, and because it's fully motorised, you set the speed and move with the belt. You stay in full control of speed and incline, and you can pause a programme whenever you like. The alloy-steel frame keeps it sturdy yet surprisingly light at 52 lbs, and it supports up to 242 lbs, so it suits a wide range of users.

The folding design is a real space-saver: raise the whole platform to vertical and reclaim the floor underneath, which makes it a great fit for small rooms. The easy-to-use control panel lets you set speed, duration, timer and intensity, while an emergency clip instantly stops the belt if you lose your footing. Your calories, distance and workout time all show clearly on the large display.

This is the best-value treadmill on our list for daily home use. Twelve automatic and manual programmes, a solid frame and a belt that's stable for both walking and running make it our top pick, and it folds away neatly when you're done. We recommend the Nero Sports for its powerful speeds, build quality and incline.

2. Sunny Health & Fitness SF-T1407M Manual Treadmill: Best Manual

The Sunny Health & Fitness SF-T1407M is ideal for medium-impact workouts and easily the cheapest way onto our list. It's a manual treadmill with a decent weight capacity and a multi-function LED display that tracks speed, time, distance and calories burned.

For a compact machine, it has a genuinely good shock-absorption system and a manual incline fixed at 13.5%, a healthy elevation for a folding manual treadmill. It folds flat, runs smoothly and uses better-than-expected deck material, all for under £400. Built-in transport wheels and a soft-drop system mean folding and unfolding takes almost no effort, and the 42-inch running surface gives you plenty of room.

The control panel covers the basics well. There are no powered speed controls (it's manual, after all), but you can still see the pace you're working at, which is rare on inexpensive manual treadmills. The main thing we'd add is pulse sensors and a tablet holder. Take notes, Sunny Health!

It misses out on pulse sensors and an adjustable incline, but the floor stabilisers and non-slip deck impressed us. If you want the lowest-cost route to a reliable home treadmill, this is the one.

3. LONTEK P5 Electric Foldable Treadmill: Best for Features

Not into weightlifting and high-impact training? Neither are we, which is why we lean on treadmills to stay toned, and why the LONTEK P5 has become a firm favourite. People love it for its easy storage, powerful motor, and adjustable speed and incline. You also get a storage box, an iPad holder and 12 preset programmes to keep sessions varied.

It's best suited to adults who want to shed a few pounds at home. Its 10 km/h top speed won't satisfy serious runners, but for the average user it's perfectly adequate. We rate it above the comparable motorised options for its sharp LCD screen and easy speed-control buttons, and it's a genuine space-saver with a solid weight capacity. Folding it up is quick, the soft-drop system lowers the deck gently onto carpet, and integrated transport wheels make it easy to move.

The LONTEK P5 folds up without fuss and spreads out with a gentle push. It reminds us of pricier machines but costs a fraction. If you want the best feature-packed budget treadmill for home use, this is our pick.

Features to look for before you buy a treadmill

Buying a treadmill takes a bit of homework. You're bringing a large machine into your home and relying on it to help you get fitter, so it pays to get one that's durable, comfortable and fast enough for your goals. A £400 budget is more than enough, so here's what to prioritise.

Space, size and weight

If you have a dedicated workout area, a larger treadmill is fine. But a space-saving, foldable model leaves room for other equipment down the line. We particularly like the Nero Sports for its foldability and compact footprint.

A treadmill's own weight matters too, because it tends to track the weight it can support. A sturdy alloy-steel frame around 55 lbs will often carry a 250 lbs user limit.

Belt length and cushioning

Average-height users can largely ignore belt length, but taller users should choose a deck that runs longer than their stride so they can walk, build pace and eventually run comfortably. A good rule of thumb is a running surface of at least 42 inches. Brands like Xterra Fitness and Merit Fitness are worth a look here.

Cushioning is the belt's surface material, and it matters most if you'll exercise on most days of the week. A well-cushioned deck makes power walking far more comfortable.

Speed and stability

Good treadmills adjust in roughly 2 km/h increments and top out around 10-12 km/h, depending on the motor. Bear in mind you may want to push the intensity over time, so an underpowered machine can hold you back.

Look for floor stabilisers to keep the machine balanced on carpet or bare floor. A wobbly treadmill is a hazard, so an emergency lanyard is a smart safety feature to have.

Warranty and budget

For motorised and hybrid treadmills especially, aim for at least a two-year warranty. These are more complex machines and aren't immune to faults. A £300 to £500 budget typically buys a dozen preset programmes, custom workout plans and progress tracking.

Types of treadmill

There are three main types of treadmill, and each has its place for burning calories and getting in shape.

Manual treadmill

Usually the cheapest option, a manual treadmill needs no electricity. Rollers under the belt move as you walk or run. The big upside is a lower injury risk, and these models fold up easily and are typically more compact by design.

Motorised treadmill

A motorised (electric) treadmill has a motor and electronic console, moving at set speeds you have to keep up with. The advantage is being able to lock in a target pace to hit your workout goal. They're larger and tend to take a permanent spot in the room, and many of the best-value treadmills, like the LONTEK P5, fall into this category, complete with a control panel, screen and sometimes a heart-rate monitor.

Hybrid treadmill

A hybrid treadmill doubles as an elliptical machine, so it's effectively two pieces of equipment in one. They're as large as electric treadmills but add features motorised models lack, such as cushioned seats for elliptical work and programmes for higher-impact exercise. They can switch between modes whenever you need.

Top budget treadmill brands

Treadmills are many things, but cheap usually isn't one of them. These three brands stood out for offering strong specs at a fair price.

Sunny Health & Fitness

Sunny Health & Fitness is based in LA and has spent over a decade in the exercise-equipment business. Its range spans treadmills, rowers, steppers, ellipticals and exercise bikes. We rate the pricing and quality, and the fact that every machine comes with assembly, usage and troubleshooting guides.

Nero Sports

Since 2004, Nero Sports has been one of the UK's largest retailers of sports and fitness gear. Its Bluetooth-enabled electric treadmills start from around £229.99 and pack in plenty of features. The brand also sells well-priced hoverboards and electric scooters.

LONTEK by UMAY

LONTEK is known for its affordable treadmills and consistently solid fitness equipment. We'd recommend its machines to anyone who wants a capable treadmill at a moderate price.

FAQ

Are Sunny Health & Fitness treadmills worth it?

Yes. They offer a good speed range and several built-in programmes that work a little like a personal trainer, and the manual incline lets you set your own pace. For the money, they're a dependable choice.

What is the safety key on motorised treadmills?

Motorised treadmills include a safety lanyard that clips to the console at one end and to your clothing at the other. If you slip, the lanyard pulls free of the console and stops the belt immediately, helping you avoid injury.

Which budget treadmill has the most workout programmes?

The LONTEK P5 has six automatic and six manual programmes (12 in total) plus a variable incline to ramp up the intensity, making it the most feature-rich pick on our list.

Final thoughts

The best treadmill under £400 should offer a useful speed range, a long enough running surface and an adjustable incline. As our picks prove, a budget machine can absolutely get you off the couch and back into shape. Our overall recommendation is the Nero Sports for its blend of power, build quality and value, with the LONTEK P5 close behind for features and the Sunny Health & Fitness as the best low-cost manual option.
