How we score. The value score is our own sum from the listed specs and Shedstore's price. It is not a customer review and we have not tested the products. For a shed: 45% is price per square foot against other sheds, 25% is guarantee length, 20% is features (floor, windows, lock, double doors) and 10% is any saving off the RRP. Bases are scored on price per square foot and guarantee, storage boxes on price per litre, guarantee and lock. Give us your space and it becomes a match score that also rewards the products that make best use of it.
Keter sheds give you the look of a timber garden shed in resin that never needs painting, treating or re-felting. This page is for anyone who wants dry, lockable storage for bikes, a lawnmower and tools without the yearly upkeep of wood.
We list 20 Keter plastic sheds sold by Shedstore, from the 6x6 Factor up to the 10x15 Stronghold, across four ranges: Factor, Newton Plus, Stronghold and the Darwin potting shed. Want a single range? Go straight to Keter Factor sheds, Keter Newton Plus sheds or Keter Stronghold sheds.
The brand has made plastic garden products since 1948 and is the best-known name in resin storage in the UK. Its sheds are made from polypropylene resin, and the better ranges use Evotech panels: double-wall resin with a moulded wood-grain texture. Up close they look like painted timber. Unlike timber, they will not rot, warp, peel, rust or dent, and the colour is UV-stabilised so it does not fade in the sun.
That is the whole point of a resin shed. A wooden storage shed needs a coat of preservative most years and a new felt roof every so often. Resin needs a wash with soapy water and a hose. Over ten or fifteen years that saving in time and paint is what makes the higher price worth it.
Every model on this page also has:
Every model listed, with the sizes and specs from the Shedstore listings. Prices change daily and the grid above always shows Shedstore's current price, so here we give bands: the Factor range sits between about £800 and £1,400, Newton Plus from about £1,300 to £2,500, and Stronghold from about £1,550 to £2,500.

Newton Plus sizes come in pairs: the same shed with the doors on the short gable end (apex) or on the long side (reverse apex). Pick by which way your garden runs, not by the size.
The Factor is the entry range and the cheapest way into a full-size model. The panels are resin reinforced with steel, with a beige wood-effect finish, a resin floor, one window, a skylight, air vents and two shelves in the box. Shedstore lists a snow load of 75kg per square metre for the 8x6 and an assembly time of about 4.5 hours for two people. It comes in 6x6, 8x6, 8x8 and 8x11. If you want a straightforward storage shed for tools and a mower, start here.
Newton Plus is the range with the most choice, from 7x7.5 right up to 17x7.5. Every size is 2.30m deep, which makes it the one to look at for a narrow plot or a side return. The panels are double-wall Evotech resin with steel reinforcement, in grey with a wood-textured finish. You get two Victorian-style windows, a full-length skylight, built-in ventilation, a heavy-duty floor and a 15 year guarantee. The layout is modular, so you choose where the doors and windows go during the build.
The Stronghold is the heavy-duty range. It is wider (3.05m) and taller (2.51m to the ridge) than the other ranges, with a steel-reinforced apex roof that Shedstore lists at up to 150kg per square metre of snow on the 10x8. The 1.525m double doors take a ride-on mower, and a 3-point locking system holds both doors shut. A full-length skylight and transom windows light the inside. It comes in 10x8, 10x11.5 and 10x15 with a 10 year warranty. For more models built this way see our heavy duty plastic sheds.
The Darwin 8x6 potting shed is a green Evotech building made for gardeners. It has five opening windows, two fixed ones and a hybrid roof that is translucent over the bench side and opaque at the back, so seedlings get light and tools stay in the shade. The listing does not include a floor, so plan a solid base. More sheds with lots of glazing are on our plastic potting sheds page.
Keter also makes the Signature, Manor, Cortina and Artisan ranges, sold direct and through other shops. Shedstore does not list those, so they are not on this page.
Measure the space in the garden, then measure what you need to store. Check the delivery route too: the flat-pack boxes must fit through a side gate or the house. As a rough guide:
Leave at least 60cm of space around the outside so you can reach the panels during assembly and get round to clean the walls later.
Every model needs a firm, level base. The floor in the kit spreads the load but it will twist on soft lawn, and then the doors stop lining up. Concrete or paving slabs are best for a large or heavily loaded shed; a plastic grid base filled with gravel works well for most sizes. Make the base a little larger than the shed footprint. Our shed base kits and adjustable shed bases cover both.
Assembly is a bolt-together job with no cutting or sawing. Plan on two people and most of a day for the bigger sizes; the flat packs for the Stronghold and the larger Newton Plus weigh well over 100kg, so have help on delivery day too.
Every model here takes a padlock, which is not included. The Stronghold adds 3-point locking on the doors. Resin panels bolt together from the inside, so there are no outside screws to undo. For alarms, hasps and locks see shed security.
Usually not. In England an outbuilding is permitted development if, among other rules, it covers no more than half the garden, is not in front of the house and, within 2m of a boundary, stands no taller than 2.5m. The Factor and Newton Plus ranges are under 2.5m. The Stronghold is 2.51m to the ridge, so set it a little over 2m from the fence or check with your council. The Planning Portal guide to outbuildings has the full rules, and Scotland, Wales and Northern Ireland differ slightly.
The closest rival is Palram Canopia, which builds polycarbonate and aluminium sheds with clear or frosted panels. A Palram feels more like a greenhouse; a Keter looks like painted timber. Compare them on our Palram Canopia sheds page. Still deciding between resin and timber? Our plastic vs wooden shed guide sets out the pros and cons, and resin sheds lists every resin model we have. You can also see the full range on Keter's own UK site.
Yes, for low-maintenance storage. The resin will not rot, warp or need painting, the panels are UV-stabilised against fading, and the 10 to 15 year guarantees are longer than most timber buildings get. They cost more up front than a basic wooden shed of the same size.
The maker says they are built to last a lifetime with the correct care. The guarantee is your firm promise: 15 years on Factor and Newton Plus, 10 years on Stronghold and Darwin.
The Factor, Newton Plus and Stronghold sheds on this page include a heavy-duty floor. The Darwin potting shed listing does not, so build it on slabs or concrete.
Any sealed building can. Vents are built into every model to keep air moving. Keep the doors closed in wet weather, open them on dry days and don't store wet mowers or damp cushions inside.
It is much harder than with timber. Resin panels fit tightly with no gaps to gnaw, and the floor is plastic. The maker itself says nothing is completely rodent proof, so keep bird seed and pet food in sealed tubs.
Yes. Keter sells spare parts online, which is handy if a panel is damaged in delivery or years later.
The Factor comes with two shelves. For the others, the brand sells shelving kits and tool racks, or see shed shelving for freestanding units.
