Garden sheds are a practical addition to any garden. You can store all your gardening tools, any equipment lying around, and even the kid’s summer toys out of sight. A tidy garden space will make you feel accomplished and peaceful in your home domain. But how much does it cost to build a shed?

You will find sheds in all price ranges from a few hundred pounds to a few thousand. This might make you curious about what makes up the price of a garden shed. We’ll try to answer some of the most frequent questions about the cost of building a garden shed, so you can have a clear idea of what to expect. We’ll also compare a cheap wooden garden shed of only a few hundred pounds to one that costs a few thousand, so you can see what makes the price difference. 

Timber sheds are the most popular shed type in the UK. So, before looking into other kinds of sheds made out of metal or plastic, let’s look at what makes up the price of a wooden garden shed.

What affects garden shed cost in the UK?

The cost to build a shed in the UK can vary significantly, even when two sheds appear similar at first glance. Before comparing a £360 model to one costing over £3,625, it helps to understand what actually drives the price.

Several key factors influence the total garden shed cost:

1. Size

The larger the shed, the more timber, roofing material and structural support it requires. Even small increases in width or height can significantly raise material and transport costs.

2. Material

Timber sheds are generally more expensive than plastic or thin metal alternatives, but they tend to offer better durability, insulation and visual appeal. Higher-grade timber, such as slow-grown Nordic spruce, will also increase cost compared to low-grade pine.

3. Wall thickness and structural strength

Thicker wall boards increase stability and lifespan. A shed built with 44mm interlocking logs will cost more than one made from 12mm panels, but it will also perform very differently over time.

4. Labour: DIY vs professional installation

Choosing to assemble a shed yourself can reduce upfront costs. Hiring professional installers increases the overall shed installation cost, but may improve long-term durability and warranty compliance.

5. Base and foundation

A shed installed directly on uneven ground will not last. Concrete bases, slab foundations or specialist base kits all carry different costs, which can meaningfully affect your total spend.

6. Extras and upgrades

Windows, double doors, shelving, security features, insulation, electrics and interior finishes can all increase the total cost. What begins as a simple storage shed can quickly become a workshop or garden office, which naturally changes the budget.

7. Location

Labour rates, material costs and delivery charges vary across the UK. Urban areas and southern regions typically carry higher installation and groundwork costs.

£360 shed vs £3,625 shed: What’s the difference?

While a £360 garden shed can seem very appealing on the surface – who wouldn’t want a shed at such a great price point? – the old saying holds true: you get what you pay for. If you look closer, you’ll see that a low-cost shed is made out of inferior materials and does not have the same structural integrity, security level, ease of use, or durability as a quality shed.

So what do you get for 360 pounds vs 3,625? We took one of the cheapest sheds we found available online and compared it to Summerhouse24’s garden shed ‘Nora’.

What this garden shed cost comparison really shows

Looking at the table, the price difference isn’t just about branding. It’s about scale, material strength and long-term durability.

The £360 shed is compact, made from thin 12mm boards and built primarily for light storage. It’s designed to hit a low price point and works best for short-term or minimal use.

The £3,625 shed is substantially larger and built from 44mm interlocking logs, which offer significantly greater structural strength. Thicker walls and floorboards improve rigidity and lifespan, while treated foundation joists and wind braces increase stability in harsh weather conditions.

Timber grade also plays a role. Lower-cost sheds often use unspecified softwood, whereas higher-end models typically use slow-grown Nordic spruce, which is denser and more dimensionally stable. Over time, this affects how the building performs in changing weather which is incredibly important in the UK’s variable climate.

Hardware, doors and guarantees are also part of the price difference. Features like double doors, higher-grade fittings and longer warranties reflect a product designed for heavier and longer-term use.

In short, the difference isn’t simply £360 versus £3,625. It’s the difference between a lightweight storage unit and a long-term timber structure.

How much does it cost to build a shed in the UK? (2026 fees explained): 

When people ask how much it costs to build a shed in the UK, what they’re really asking is:

What will I actually end up paying once everything is included?

The answer depends on size, materials, base, installation, your location and whether you’re building it yourself or hiring professionals. Below is a realistic 2026 guide to typical UK garden shed costs.

Shed type / Size	Typical UK garden shed cost range
Small wooden shed	£1,500 – £3,500+
Medium timber shed	£2,500 – £4,000
Large shed or workshop	£4,000 – £6,000
Brick-built shed	£5000+
Metal shed	£300 – £1,500
Plastic shed	£250 – £1,200

These prices reflect supply-only costs and will increase once base preparation, delivery and installation are factored in.

Shed material costs

Sheds made of different materials have different price ranges. The most expensive ones are made from brick and are very durable, but also require quite a large budget.

There’s the classic wooden shed, which can be either built from scratch or bought from a reseller or straight from the makers and assembled at home by a tradesman or yourself. Timber sheds vary significantly depending on wall thickness and timber quality. A 12mm overlap shed sits at the lower end of the market, while a 44mm interlocking log construction sits in a completely different durability category.

Then we have the metal sheds, which are often less costly compared to decent wooden garden sheds. The caveat is that they can be noisy during rain and they lack the visual appeal of a wooden shed. 

There are also plastic sheds, some of which are very cheap, but susceptible to sun damage. UV rays damage plastic over time, making it brittle. An eco-friendly plastic shed made of recycled plastic can be a good option if you’re concerned about using plastic, though these sheds are more expensive. One good thing about plastic sheds is that they don’t require maintenance. On the other hand, they can heat up quite a bit in the sun and you may also face ventilation challenges. With metal and plastic sheds it’s better not to keep anything in the shed during hot summer weather that is not meant to be stored in high temperatures.

Material type	Price range	Things to consider
Timber	£1,500 – £15,000+	Better insulation, more durable if quality timber is used
Metal	£300 –  £1,500	Lower upfront cost but can be noisy and prone to condensation
Plastic	£250 – £1,200	Low maintenance and cheap but may fade or become brittle over time, especially when exposed to heat
Brick	£5000+	Long lifespan but highest cost and requires full construction

Shed installation cost

Installing a shed takes about 1-2 days on average, depending on the size and complexity of the building. Installation costs can vary from a few hundred pounds to over a thousand. If plumbing, electrics or insulation are being added, professional installation is usually recommended.

Summerhouse24 garden shed kits are great for DIY enthusiasts if you’re looking to save money on installation costs. Whilst an installation team will surely get the job done faster for you, if you’re looking to put up your shed by yourself, you’ll just need an extra pair of hands and you’ll be done in a day or two. If you’re planning a DIY installation it’s a good idea to be completely honest about your level of DIY skills or enlist the help of a friend who knows their way around a spirit level. 

Installation type	Typical cost range
DIY installation	£300 – £500 (for basic tools and fixings)
Professional installation	Approximately £1,250+

Shed base costs

A solid base protects your shed from moisture and movement. Cutting corners here often leads to problems later. That said,

Shed base costs can vary a lot, depending on the type of base you’ll choose for your garden building. Concrete and paving slabs are a popular option and there are even plastic and wooden bases available. A wooden base will often be supported by spikes that go directly into the ground. The important thing is to get a proper base so that your shed lasts a long time. If you’re not sure what is the right choice, consult an experienced seller.

Getting a concrete base built will cost around £100 per m3. It’s often more cost-effective to use concrete blocks. Plastic shed bases cost from less than a hundred pounds all the way up to £600-£700, depending on the size.

A great way to save money on foundation costs is to use a foundation kit like the one that Summerhouse24 provides. It’s up to 80% cheaper compared to a concrete foundation and can be used for any garden building or shed up to 45m² in size.

Base type	Cost range
Concrete slab	£100 – £160 per m³
Paving slab	£40 to £80 per m²
Plastic grids	£15 to £55 per m²
Timber frame	£400–£1,000 per m²
Foundation kit	£560 – £960

If you’re investing in a shed that’s built to last, wall thickness, timber grade and structural detailing make all the difference. Summerhouse24 sheds are crafted from slow-grown Nordic spruce with solid log construction, treated foundation joists and long-term durability in mind.

4 steps to planning your garden shed

1. Check whether you need planning permission: 

In most cases, you won’t need planning permission to build a garden shed in the UK. Sheds usually fall under permitted development rights.

However, permission may be required if:

• The shed takes up more than 50% of the land around the original house
• It exceeds 2.5m in height when within 2m of a boundary
• You live in a listed building
• Your property is in a Conservation Area, Area of Outstanding Natural Beauty, National Park or similar designated area

If you’re unsure, checking with your local council before purchasing can prevent delays later.

2. Consider what you’ll use the shed for: 

Are you using it for basic storage, a workshop, a home office or something more substantial?

Your intended use affects:

• Required size
• Wall thickness
• Security features
• Insulation needs
• Base requirements

Being clear about use upfront helps you avoid undersizing — which is one of the most common shed-buying mistakes.

3. Choose the location: 

Select a level area with good drainage.

Make sure:

• Water flows away from the structure
• Guttering directs rain safely away
• The base is solid and stable
• There’s enough clearance around the shed for maintenance

Planning placement properly extends the life of the building significantly.

4. Budget properly: 

Factor in:

• Shed purchase cost
• Base preparation
• Delivery
• Installation (if not DIY)
• Timber treatment
• Optional extras

If assembling yourself, allow at least 1–2 days depending on size. Also make sure you have the time to apply the treatment, as this needs to be done fairly soon after a wooden shed is installed. It’s not worth skipping or delaying, since this is the most important factor in determining how long your garden shed will last.

Conclusion

The cost to build a shed in the UK can vary dramatically, from a few hundred pounds for a small basic structure to several thousand for a larger, high-quality timber building.

The biggest differences in price usually come down to size, material quality, structural thickness, base preparation and whether you choose DIY or professional installation. A cheap shed may work for short-term storage, but a well-built shed is more durable, more secure and often better value over time.

Before buying, think about how you’ll use the space, where it will sit in your garden and whether you want something temporary or something that will last for years. Understanding the full cost involved helps you make the right decision from the start.
