Quick answer
The best garden shed is the one that suits what you'll keep in it. For general storage, a dip-treated timber shed with 12mm tongue and groove cladding is a sound, affordable choice. For a workshop or valuables, look for a heavier frame, pressure-treated timber and a proper lock. If you never want to treat or re-felt anything, a steel shed is the low-maintenance option. Whatever you buy, check the cladding (tongue and groove or shiplap, not thin overlap, if you want it to last), how the timber is treated, the roof covering, the floor and the guarantee, and put it on a firm, level base.
There's no single "best shed" for everyone. A shed for a mower and a few tools, a workshop you'll stand in all weekend, and a secure home for two bikes need quite different things. This guide explains what actually makes a shed good, what the jargon means, and which of the ranges we sell suit each job. We haven't ranked brands against each other; each range has its own strengths, and we've said honestly what they are.
Start with what the shed is for
Budget storage: garden tools, the mower, bits and bobs
If the shed is simply for storage, you don't need the heaviest specification. Put the money into the right size and a good base.
- Power Sheds: the Overlap Apex and Overlap Pent are the budget-friendly end of the range. The standard Power Sheds range steps up to 12mm tongue and groove cladding on a 44x28mm frame, dip-treated, with a felt roof.
- Suresheds: the Hi Pex and Pent-Dale are the budget-friendly models. Suresheds use tanalised (pressure-treated) timber with a choice of 12mm, 16mm or 20mm tongue and groove cladding, and deliver and install free within 50 miles of their Rotherham factory.
- Shedlands: the Dalby Apex and Dalby Pent are the everyday range.
- DIY Sheds: flat-packed self-assembly kits in pressure-treated tongue and groove shiplap, and you can set your own spec with our Shed Builder.
Heavy-duty sheds and workshops
If you'll be working inside, fitting benches or storing heavy kit, the frame matters as much as the cladding. A thicker frame keeps the building rigid, holds shelving better and stops doors dropping over time.
- Power Sheds Premium: the Power Premium Apex Shed uses a 58x44mm pressure-treated frame (doubled in key areas), pressure-treated 12mm tongue and groove throughout, and carries Power Sheds' 20-year guarantee against rot, decay and insect infestation.
- Suresheds workshops: the Wharfedale Workshop is built on a heavier 3"x2" tanalised frame, in sizes up to 24x12ft. The Ribblesdale Tool Store is the other workshop-style option.
- Shedlands Heavy Duty: the Heavy Duty 50x50mm Framed Building steps up the frame size, with diagonal cross bracing and heavy-duty mineral felt.
- Sovereign: a large range with installation included in the price of every building, a 3-lever lock and handle as standard, and cladding upgrades on most models. See the Sovereign buying guide.
Low-maintenance metal sheds
Lifelong steel sheds are for anyone who wants storage without the upkeep. There's no treating, painting or re-felting, and the steel structure carries a 15-year guarantee. Lifelong's own team delivers and installs the building, and no concrete or slab base is needed on level ground. Apex sheds come 6ft to 12ft wide and pent sheds 6ft to 10ft wide, with an anti-condensation roof membrane and an 18mm OSB floor.

Potting sheds
A potting shed has a glazed side for bringing on seedlings, plus storage at the other end or underneath the bench.
- Power Sheds: Apex and Pent Potting Sheds, Premium versions, and Potting Shed Combis that split the building into a potting area and a separate store.
- Sovereign potters: from the compact Bath Mini Potter to the Frome Maxi Potter and the Glastonbury Glass Roof Potter, installed for you.
- Suresheds Cotterdale and the Shedlands Potting Shed also combine growing space with storage.
Summerhouse-sheds (half summerhouse, half store)
If you'd like somewhere to sit and somewhere to keep the garden furniture, a combi building splits the space in two: a summerhouse at one end and a store at the other.
- Suresheds Kingsdale Combi: in Contemporary or Georgian styles, with apex or pent roofs.
- Browse all summerhouses for more layouts.
Bike storage
- Power Pent Bike Shed: extra-wide double doors and a low pent roof that tucks against a fence, useful in side passages.
- Security sheds: the Power Apex Security Shed has a pre-fitted 5-pin cylinder lock with a 50mm bolt. Shedlands (Security Apex) and DIY Sheds (Security Apex) also have security models with stronger doors and extra locking.
- Steel: a Lifelong steel shed with the deadlock upgrade and lock cover.

Cladding: overlap, shiplap, tongue and groove and loglap
Cladding is the boarding on the outside walls. It does most of the work keeping weather out, so it's one of the biggest differences between a cheap shed and a good one.
| Cladding | What it is | Good for |
|---|---|---|
| Overlap | Rough-sawn boards laid so each one overlaps the one below. | Lowest-cost storage. Less weather-tight and less rigid than interlocking boards. |
| Shiplap | Machined boards that interlock, with a shaped edge that helps rain run off. | A tidy, weather-resistant finish on most mid-range and premium sheds. |
| Tongue and groove | Each board has a tongue on one edge that slots into a groove on the next, making a tight, flat wall. | A strong, weather-tight wall. Many "shiplap" boards are also tongue and groove. |
| Loglap | Interlocking boards with a rounded face so the building looks like it's made of logs. | A log-cabin look on a framed building. It's still cladding on a frame, not a solid log wall. |
Finished vs nominal thickness
Cladding thickness is sometimes given as a nominal size, which is the size of the board before it's planed and machined into its profile, and sometimes as a finished size, which is what you actually get. The finished board is a few millimetres thinner. For example, Sovereign Loglap is 19mm nominal and 15mm finished. When comparing sheds, check whether both figures are finished sizes, or you may not be comparing like with like. Thicker boards generally make a stiffer, more weather-resistant wall.
What is the best wood for a shed?
Almost all timber sheds are made from softwood, usually spruce (sometimes sold as whitewood) or pine (often called redwood). Both are good shed timbers. What matters more than the species is how the timber is treated and how thick the boards and frame are.
- Pressure-treated (tanalised): preservative is forced deep into the timber under pressure, giving long-lasting protection against rot and insects. It's the better choice for longevity and usually comes with a longer guarantee. Suresheds and the Power Sheds Premium range are pressure-treated, and DIY Sheds' timber kits use pressure-treated tongue and groove shiplap. For timber touching the ground, such as base frames, look for timber rated for ground contact: the Power Sheds Shed Base Kit uses UC4 pressure-treated timber.
- Dip-treated: the timber is dipped in preservative at the factory, which protects the surface. It keeps the price down but needs re-treating when it's built and then every year. The standard Power Sheds range is dip-treated, and its 10-year guarantee depends on that annual re-treatment.
Power Sheds use Scandinavian timber. Our timber care guide explains how often to treat each type.
Roof and felt
- Standard felt: fine for many sheds, but it's the part most likely to need replacing. Check it every autumn.
- Heavy-duty felt and felt tiles: thicker and longer-lasting. Several ranges offer a heavy-duty felt upgrade, and we sell heavy-duty felt and felt tiles.
- EPDM rubber roof: a one-piece rubber membrane that's low maintenance. It's an upgrade on Power Sheds, Suresheds and Sovereign buildings. Suresheds give a 25-year warranty on the EPDM roof upgrade.
- Roof boards: the felt sits on boards, so a tongue and groove roof (12mm on Power Sheds) is sturdier than thin sheet material.
Floor and bearers
The floor takes the most wear, especially with a mower or workbench. Look at the floor board thickness and whether the floor is pressure-treated. Power Sheds floors are 12mm tongue and groove, and there are upgrades such as the Sovereign Pressure Treated Heavy Duty Floor and the Shedlands Heavy Duty 22mm Floor Boards.
Underneath the floor are the bearers, pressure-treated timber rails that spread the weight and hold the floor clear of the base so air can move underneath. A shed is only as good as the base it sits on, so read our base guide, which includes a section on shed bearers.
Security
- Look for a proper lock rather than a simple hasp. Power Sheds security models have a pre-fitted 5-pin cylinder lock (50mm bolt, or 70mm on the Premium Security Shed), and every Sovereign shed, potter and summerhouse has a 3-lever lock and handle as standard.
- Stronger doors and hinges matter as much as the lock. The Sovereign Security Bolt & Hinge Set is an easy upgrade.
- Windowless or high-window designs keep valuables out of sight.
- Steel and concrete buildings are harder to break into than standard timber cladding.
Guarantees
Guarantees come from the manufacturer and vary by brand. These are the figures on our Warranty & Guarantees page:
- Power Sheds: 10 years (up to 20 years on selected products) against rot, decay and insect infestation, provided the building is re-treated annually and kept on a firm, level base.
- Suresheds: 10 to 15 years, varying by range, plus a separate roof warranty (25 years on the EPDM upgrade, 12 months on standard felt).
- Lifelong Steel Sheds: 15 years on the steel structure.
- Shedlands and DIY Sheds: varies by building. We'll confirm the terms before you order.
- Sovereign: Vista Collection garden rooms carry a 10-year warranty. For other Sovereign buildings, ask us and we'll confirm the cover before you order.
Most timber guarantees depend on a suitable base and regular re-treatment, so read the terms.
Common questions
What is the best wood for a shed?
Most sheds are made from softwood such as spruce or pine (redwood), and both work well. How the timber is treated matters more than the species: pressure-treated (tanalised) timber lasts longest and usually carries a longer guarantee, while dip-treated timber costs less but needs re-treating every year.
Is tongue and groove better than shiplap?
Both are good. Tongue and groove boards slot tightly together for a strong, weather-tight wall, and shiplap has a shaped edge that helps rain run off. Many shed boards are tongue and groove shiplap, combining the two. Both are a clear step up from overlap cladding.
What thickness of shed cladding should I choose?
12mm tongue and groove is a common, sound standard for storage sheds. Thicker cladding, such as 16mm, 18mm or 20mm, makes a stiffer, more weather-resistant wall, which is worth having for workshops or larger sheds. Check whether the thickness quoted is the finished or nominal size.
Are metal sheds better than wooden sheds?
They suit different people. A steel shed needs no treating or re-felting, and Lifelong steel sheds are installed for you with a 15-year guarantee on the structure. Timber offers more styles and sizes and is easier to fit out with shelves and hooks, but needs regular treatment.
Do I need a base for a shed?
Yes, every timber shed needs a firm, level base that keeps it off damp ground, such as concrete, paving slabs, a timber base frame or plastic supports. Lifelong steel sheds are the exception: they're installed without a concrete or slab base on level ground.
