The best incline treadmill lets you turn a flat walk or run into a proper hill session without leaving the house. Raising the incline makes your legs work harder, burns more calories and takes some of the impact off your joints compared with running on the flat. It is also the engine behind the hugely popular 12-3-30 workout, where you walk at a 12 percent incline and 3mph for 30 minutes. If you want any of that at home, you need a machine with a genuine powered incline rather than a flat walking pad.
We have pulled together five incline treadmills available in the UK, ranked from our best overall down to a budget walking pad, covering powered incline running machines and compact options for smaller rooms. Below you will find what each one does well, who it suits and an honest downside, so you can pick the right one for your space and budget.
How we chose
We researched the most popular and best-reviewed incline treadmills on Amazon UK, then cross-checked owner feedback and current expert reviews from UK fitness sites. We have not physically tested every machine here, so this is a researched buying guide rather than a hands-on test. Prices and warranty terms were correct at the time of writing and can change, so always confirm the current details before you buy.
1. JLL S300 Digital Folding Treadmill: Best Overall
Our pick for the best incline treadmill in the UK is the JLL S300. It is JLL's best-selling treadmill and one of the most reviewed home running machines on Amazon UK, which tells you a lot about how well it sells and how owners rate it.
The S300 gives you 20 levels of digital (powered) incline that you adjust at the touch of a button while you are moving, so you can build hills into a run or set up a steady incline walk. It pairs that with a 4.5HP motor, a speed range of 0.3 to 16km/h, 15 built-in programmes and a 16-point cushioned deck to ease the load on your knees. The frame folds with a soft-drop hydraulic system and rolls away on transport wheels, and the maximum user weight is 120kg. The main downsides are a fairly narrow 132 by 41cm running belt and no Bluetooth or app connectivity, so taller runners and gadget fans may want to look further down the list. For most people wanting reliable incline training at a sensible price, this is the one to get.

If you want a recognised big brand, the Reebok GT40z is our premium pick. It is the upgraded version of Reebok's popular GT40 line and one of the most affordable name-brand machines that still reaches a true 12 percent powered incline.
You get 12 levels of power incline, a top speed of 18km/h from a 2.0HP motor, a 130 by 45cm deck with Reebok's One Series cushioning, and 43 workout programmes on a clear 5-inch LCD screen. Unlike the JLL machines it adds Bluetooth, so you can sync with apps such as Zwift and Kinomap for guided rides and virtual routes. It folds with a soft-drop system and has transport wheels. The honest catch is the motor: at 2.0HP it is less powerful than the JLL units, so it suits walkers and steady joggers more than heavy daily runners. If brand reassurance, app support and a long motor warranty matter to you, it is a strong choice.
Check the warranty
Reebok lists a long motor warranty on this model, but warranty terms are correct only at the time of writing and may have changed. Confirm the current cover with the seller or manufacturer before you buy.
3. JLL T350 Digital Folding Treadmill: Best for Runners
The JLL T350 is the S300's bigger sibling and our pick if running, rather than walking, is your priority. It shares the same trusted JLL build but adds a higher 18km/h top speed for faster intervals and sprints.
Like the S300 it has 20 levels of digital incline that adjust on the move, a 4.5HP motor and a 16-point cushioned deck, but it also brings Bluetooth speakers, USB connectivity and more workout programmes. The maximum user weight is 120kg and it folds into a Z shape with the same soft-drop lever system. The running belt is a similar width to the S300, so it is not the widest deck around, and the extra features push the price up over the S300. If you mostly walk, the cheaper S300 makes more sense, but if you want to run at pace with incline and a bit more on-board tech, the T350 is the better fit. It is one of the more capable treadmills in this price bracket.

For a smaller room or a flat where a full-size running machine simply will not fit, the CITYSPORTS 8% Incline Folding Treadmill is our compact pick. It is a 2-in-1 design that works as an under-desk walking pad and as a low-profile treadmill with a fold-up handrail.
It offers an 8 percent incline, a 1 to 12km/h speed range from a 1400W motor, a dual LED display, remote control and a companion app, with a 120kg weight capacity. It is light enough to wheel away and slide under a bed or sofa, which is its main appeal. The trade-offs are clear: the incline tops out lower than the running machines above, the deck is narrower and the lower power suits walking and light jogging rather than serious running. If your main goal is incline walking and daily steps in a tight space, it does that job well for the money.

If you want the lowest price and your aim is incline walking rather than running, the CITYSPORTS 10% Incline Walking Pad is our budget pick. At around £100 at the time of writing it is far cheaper than the running machines above, while still giving you a powered incline.
It has four incline settings up to 10 percent, a 1 to 6km/h speed range, an LED display, Bluetooth for music and shock absorption underfoot. It is compact, quiet and needs no assembly, so you can unbox it and start walking. The obvious limits are the low 6km/h top speed, which is for walking only, and a smaller belt, so it is not built for running or for tall, heavier users. As a low-cost way to get your steps in on an incline while you work or watch TV, it is hard to beat on price.
Walking, not running
A walking pad like this is designed for walking and gentle inclines, not running. If you want to jog or run with incline, choose one of the powered running machines higher up this list instead.
Which incline treadmill should you buy?
We compared the most popular and best-reviewed incline treadmills on Amazon UK and picked these five for their incline range, build quality and value. Here is the quick summary:
- Best overall: the JLL S300 gives you 20 powered incline levels, a strong motor and a folding frame at a fair mid-range price, which is why it is our top choice for most buyers.
- Best premium: the Reebok GT40z is the big-brand option, with a 12 percent power incline, app connectivity and a long motor warranty.
- Best for runners: the JLL T350 adds a faster 18km/h top speed and on-board tech for those who want to run, not just walk.
- Best compact: the CITYSPORTS 8% Incline Treadmill folds away for small spaces and doubles as an under-desk walker.
- Best budget: the CITYSPORTS 10% Incline Walking Pad is the cheapest way to walk on an incline at home.
If you are not sure how much to spend, the JLL S300 is the safe all-rounder. Walkers on a tight budget should look at the CITYSPORTS pad, while keen runners will get more from the JLL T350.

Frequently asked questions
Which is the best incline treadmill in the UK?
Our top pick is the JLL S300 Digital Folding Treadmill. It offers 20 powered incline levels you can change mid-run, a 4.5HP motor, speeds up to 16km/h and a folding frame, all at a sensible mid-range price. It is one of the best-reviewed home treadmills on Amazon UK.
What is a good incline percentage on a treadmill?
For most home users a maximum of 10 to 15 percent is plenty. A 12 percent incline is steep enough for hill training and for the popular 12-3-30 walking workout (12 percent incline, 3mph, 30 minutes). Many machines list incline as levels rather than a percentage, so check the spec before you buy.
Is a powered incline better than a manual incline?
Yes, for most people. A powered (motorised) incline can be adjusted at the touch of a button while you keep moving, so you can build hill intervals into a run. A manual incline has to be set by hand before you start and cannot be changed mid-workout.
Does walking on an incline burn more calories?
It does. Raising the incline makes your muscles work harder, so you burn more calories and recruit more of your glutes and calves than walking on the flat, all with less impact on your joints than running. That is why incline walking has become so popular.
Do I need much headroom for an incline treadmill?
It is worth checking. At full incline the rear of the deck rises and you stand higher than normal. If you are tall or have a low ceiling or sloped loft, measure your height while standing on a raised deck before you buy.
