The best budget treadmill in the UK doesn't have to mean cheap and flimsy. After testing a wide range of affordable models, we were genuinely impressed by how much you can get for under £250. A home treadmill is one of the few pieces of fitness kit you want to be reliable around the clock, so the trick is finding a low-cost model that still feels solid and lasts.
Affordable treadmills in the UK have shot up in availability as brands rush to cash in on a fast-growing home-fitness market. The downside is that cutting costs often produces poor-quality machines that break within a year or sooner. So how do you find a genuinely good budget model without sacrificing quality and reliability? We tested treadmills from brands large and small to find out.
To be clear on our definition of "budget", we focused on treadmills costing less than £250. One or two sit slightly above that, but most are significantly below, and we've included options for those on the strictest budgets as well as for buyers happy to spend a little more for a noticeable jump in quality or features.
Our budget benchmark
Everything in this guide costs under £250 except a couple of picks just under £300, which we felt earned their place on build quality and longevity. Several of these treadmills include features usually reserved for machines above £500.
If you're looking to spend around £200 on a treadmill, this is our undisputed top pick. The LONTEK comes well packaged and is quick and easy to set up, folds down flat for storage, and looks the part with good-quality materials and a clean design.
In testing it felt well-built and sturdy. Where some low-cost treadmills feel as though they might give way under strain, this one doesn't. The motor is quiet enough to run while watching TV without turning up the volume, and it reaches a top speed of 10km/h (around 6mph). There's even a built-in Bluetooth speaker for music.
The LED display tracks calories, time, distance, heart rate and average speed, but the best part is the app connection. It gives you instructor-led runs, studio-style classes and a virtual running track, streaming hundreds of workouts to your phone, which sits in the on-board holder. Not interested in the app? Use the holder to watch TV or video while you run instead. Two handlebar heart-rate sensors proved accurate in our testing, and the running platform feels wide and stable. This is an easy-to-use, high-quality treadmill with everything you could ask for.
Check price on AmazonThe first thing you'll notice is the striking yellow accents, but that's not why the Fit4home is one of our favourites. It's strong, very sturdy and well-built for the price, and folds up compactly to tuck away after a workout.
At £229.99 (at the time of writing), it packs in features rarely seen below £400. From our testing it was the only treadmill at this price with three adjustable incline options, all easy to change on the fly. A bright display offers 12 preset programs out of the box and stays lit long after your session, so you can snap a photo of your stats: calories, time, speed and distance. There's a holder on the front for a phone, iPad or book, control buttons built into the handlebars, and heart-rate sensors in the grips.
In use it did the job without issues: not too loud, solid underfoot, and good for speeds up to 10km/h, with a maximum load of 100kg.
Check price on AmazonAt sub-£200 (at the time of writing), this is an excellent choice for anyone who wants a good-quality treadmill without breaking the bank. One thing to note: "Buyer Empire" is the seller, and the treadmill itself is branded Speedy Sports, so don't worry you've received the wrong machine on delivery. It feels sturdy in use and comes with an LCD screen for the usual stats (speed, distance, time, calories and heart rate) plus a solid list of built-in programs.
With a top speed of 10km/h (around 6mph), it offers plenty for most home users, more than enough for a typical home workout, and it's very quiet, which is ideal indoors. You also get water-bottle holders and Bluetooth/MP3 connectivity for your phone. The maximum user weight is 85kg, making this a great pick for anyone looking to spend less than £200.
Check price on AmazonThis is our top pick for buyers who want to spend as little as possible but still enjoy the benefits of a home treadmill. It's a manual walking treadmill with no motorised belt, which means a quiet workout with no need for a nearby plug socket. We loved being able to wheel it in front of the TV whenever we wanted.
It's lightweight, compact and folds away when not in use. Despite having no motor, it still includes an LCD screen tracking speed, calories, time and total steps. It's important to stress this is a walking treadmill, not built for running. We managed a light jog, but anything more is very difficult. If you just want to stay fit and healthy at home without running, it works well, with a maximum capacity of 100kg (around 15 stone).
Check price on AmazonThis Sportstech is a real beast and an excellent choice if you can stretch your budget a little further. Sturdy, compact and practical, it feels like a high-end machine. We've picked it for big and tall users thanks to a higher-than-average 120kg weight capacity (just under 19 stone) and wider surfaces either side of the belt. The running surface feels strong and easy on the joints, with enough grip to sprint confidently.
It was also one of the quietest treadmills we tested. Even at full speed (10km/h) we could comfortably watch TV. The LCD display offers 13 programs (12 preset, one manual) at varying difficulty, suiting beginners and experienced runners alike, and tracks calories, time, distance, speed and heart rate. A standout extra is the self-lubricating system, which keeps the belt maintained automatically. That's easy to forget otherwise, and a common cause of a shortened treadmill lifespan. It folds flat quickly with a single clip release and pairs with a mobile app for progress tracking, fitness videos and coaching. If you need something that caters to a heavier weight on a budget, this is the one to get.
Check price on AmazonCITYSPORTS features twice in this guide, and this is the higher-end model. It's a motorised walking treadmill, ideal for anyone who isn't interested in running but still wants an electric machine with plenty of features.
It comes with or without a support bar. We chose the version without, to try it at a standing desk, and loved it. With no handlebar in the way, we could keep working through the day while getting steps in, then tuck it under the desk afterwards. The display shows speed, time, distance and calories burned. At full speed (6km/h, around 4mph) it's incredibly quiet, and we watched TV and videos without any issue. A remote control lets you adjust the speed at any time. With a maximum capacity of 100kg, it's a great pick for an easy-to-use, compact walking treadmill with handy extras.
Check price on AmazonIf you can spend a little more, the Nero Sports could be a great fit. At just under £300 it may not count as budget for everyone, but it earns its place because longevity matters. The last thing you want is to replace equipment every year.
That's where the Nero Sports shines. It's strong and sturdy, with a maximum weight limit of 110kg (roughly 17.5 stone) and, notably, a lifetime warranty on the motor, so if the motor fails you could have it repaired or replaced free of charge. There's also a two-year warranty on the frame and parts. Features-wise you get an LED display showing time, speed, distance and calories, plus 12 built-in programs covering beginner and experienced runners. It folds flat for storage, hits a top speed of 10km/h (around 6mph), and feels sturdy in use. Set-up is quick, and you can connect your phone via Bluetooth to track progress through an app called FitShow.
Check price on AmazonThis is the second CITYSPORTS on our list, and the more budget-friendly option. It's another motorised walking treadmill without handlebars, ideal if you only want to walk and need something compact and well-made.
Lightweight and easy to set up, the 440W model is a little less powerful than its bigger brother but still packs in great features with a quality build. The screen shows speed, time, distance, calories and steps, and the included remote lets you adjust speed quickly. We were impressed by how quiet it is, perfect for use while working or watching TV, and the built-in Bluetooth speakers let you play music straight from your phone. A nice touch is the on-screen notification when the belt needs lubricating, which helps extend its life (and is easy to do yourself). With a 110kg maximum weight and a 6km/h top speed (around 4mph), it's an ideal low-cost walking treadmill.
Check price on AmazonThe Confidence Ultra 200 is an excellent treadmill for the money. At £249.99 (at the time of writing) it sits at the higher end of our budget range, but it's sometimes worth spending a little extra for a noticeably better machine. It's fully motorised and built for home use, with a control panel covering calories, speed, distance, time and heart rate, plus good-quality integrated speakers so you can play music from your phone as you run.
Out of the box it's heavy and sturdy, which gives confidence it won't break easily. It folds flat for storage and has three manually adjustable incline levels to ramp up the difficulty. With a top speed of 10km/h and 12 preset programs at varying difficulty, it covers everything you need for home fitness. Extras include an emergency stop clip, a side bottle holder and a 110kg maximum weight capacity. It's also easy to move and store, which is handy when you're tired after a run.
Check price on AmazonLast but not least is the Bigzzia. It's another treadmill without handlebars, but unlike the walking-only models above, this is a fully-fledged running treadmill, ideal if you want a space-saving machine you can actually run on.
The sleek, compact Bigzzia has a top speed of 10km/h and a 110kg maximum weight capacity, enough for most home users. It's also keenly priced, one of the cheapest in this guide. The screen gives real-time speed, time, distance and calories, and the motor is very quiet, so you can watch TV or work while you use it. Best of all, it arrives fully assembled, with no screwdrivers or hex keys needed, just plug in and run. At just 23.5kg it's lighter than many rival budget treadmills, so it's easy to move and store, and it comes with a controller for adjusting speed as you run.
Check price on AmazonEvery treadmill here has been tested by us. We ranked them on cost, build quality, features, noise levels and longevity, paying particular attention to how sturdy each machine felt and how reliable it's likely to be over time. Some pricier picks fall just outside the strictest budgets, but we've also included some very low-cost treadmills that genuinely impressed us and proved well worth the money.
Whatever your budget, there should be a treadmill here to suit you. The budget treadmill market in the UK has come a long way, and manufacturers seem to have listened. Several of these felt as good as machines costing far more. If you have any questions about budget treadmills or any of the models featured, leave a comment below.
For most home users, the LONTEK Motorised Treadmill is our top pick at around £200. It's sturdy, quiet, folds flat and even connects to a workout app. If you want to spend less, the Sunny Health & Fitness manual walking treadmill is our pick for the strictest budgets.
We define 'budget' as under £250. The treadmills in this guide range from low-cost manual walking models to motorised running machines just under £300. The budget treadmill market has improved hugely, so you can now get features that used to appear only on machines above £500.
Many are. Some budget brands cut corners and break within a year, but the models in this guide were chosen after hands-on testing for build quality, reliability and features. Several felt as solid as machines costing far more.
Walking treadmills are compact, often without handlebars, and top out around 6km/h, which makes them ideal for use under a desk or in front of the TV. Running treadmills reach about 10km/h and have a longer, more cushioned belt. Some manual walking treadmills have no motor at all, so they need no plug socket.
