TL;DR — Shed Installation Cost At A Glance
- Assembly labour to install a shed costs £200–£600, depending on the size and complexity of the shed.
- The shed unit itself costs £150–£1,500+, from a small timber overlap shed up to a large tongue-and-groove or metal building.
- A solid base — slabs, concrete or a base grid — usually adds £150–£600, and a hard-wearing roof (felt shingles or EPDM) £250–£450.
- London and the South East add roughly 20–30% to labour.
- The main cost drivers are the shed size and material, the base, the roof covering, access and any old-shed removal.
- A proper base is essential — a shed set on uneven or damp ground shifts, sticks and rots years earlier than one on a firm, level base.

Add to Preferred Sources How Much Does Shed Installation Cost In 2026?
Having a shed professionally installed in the UK costs £200–£600 in assembly labour, on top of the shed unit (£150–£1,500 or more) and, in most cases, a base (£150–£600). London and the South East add roughly 20–30% to the labour. So the all-in figure depends on three separate things: the shed you buy, the ground it sits on, and the work of building it — and it's worth pricing each rather than looking at any one in isolation.
The shed unit ranges widely. A small 6×4 timber overlap shed is the budget end; a larger 8×6 or 10×8 shed in shiplap or tongue-and-groove timber, or in metal or plastic, costs considerably more. Assembly labour scales with size and design — a simple apex shed goes up quickly, while a large shed, one with a complex roof, or a summerhouse-style building takes longer.
The part people most often underestimate is the base. A shed needs a firm, level and free-draining foundation — paving slabs, a concrete pad or a plastic base grid over compacted hardcore. Set a shed straight onto grass or uneven ground and the floor rots, the frame twists, doors jam and the whole structure fails years early. A good base is the difference between a shed that lasts a decade or two and one that's a problem within a couple of winters. The roof covering matters too: basic felt is cheap but needs replacing every few years, while felt shingles or EPDM rubber last far longer for £250–£450.
Here's what you can expect to pay:
| Job | Rest of UK | London & South East |
|---|---|---|
| Assembly labour (small–medium shed) | £200–£400 | £250–£500 |
| Assembly labour (large shed) | £400–£600 | £500–£750 |
| Base preparation | £150–£600 | £200–£750 |
| Roof re-felt / EPDM covering | £250–£450 | £300–£550 |

Shed Installation Cost By Size
Bringing the unit and assembly together shows the realistic all-in picture by shed size (a base is added on top). Here's a typical breakdown:
| Shed size | Shed unit | Assembly labour | All-in (excl. base) |
|---|---|---|---|
| Small (6×4) | £150–£400 | £150–£250 | £300–£650 |
| Medium (8×6) | £400–£800 | £250–£400 | £650–£1,200 |
| Large (10×8+) | £800–£1,500+ | £400–£600 | £1,200–£2,100+ |
| Base (slabs or concrete) | — | £150–£600 | added on top |
| Old shed removal and disposal | — | £150–£400 | added on top |
Removing and disposing of an old shed, and preparing a fresh base, are the two extras that most often add to a straightforward assembly.
What Affects The Cost Of Shed Installation?
Several factors decide where you land in the ranges above.
1. Shed Size And Design
A small apex shed assembles quickly and cheaply. Larger sheds, and those with complex roofs, verandas or summerhouse features, need more time and sometimes two people, raising the labour.
2. The Shed Material
Timber overlap is cheapest; shiplap and tongue-and-groove cost more but are sturdier and more weatherproof. Metal and heavy-duty plastic sheds sit at different price points and assemble differently.
3. The Base
A firm, level base is essential and priced separately. Paving slabs are mid-range, a concrete pad the most durable and involved, and a plastic base grid a quicker modern option. Difficult or sloping ground costs more to prepare.
4. Roof Covering
Basic felt is included with many sheds but is short-lived. Upgrading to felt shingles or EPDM rubber costs more upfront but lasts far longer and avoids repeat re-felting.
5. Access And Old-Shed Removal
Carrying panels down a narrow side return or through the house adds time. Removing and disposing of an existing shed before the new one goes up is a separate charge.
6. Your Location
London and the South East run roughly 20–30% higher than the rest of the UK, reflecting higher labour and disposal costs.
What's Included — And What's Not
| Typically included in a shed installation | Usually charged separately |
|---|---|
| Assembling the shed panels, roof, floor and door | Building or laying the base (slabs, concrete or grid) |
| Fixing the structure together securely and squaring it up | Upgraded roof coverings such as felt shingles or EPDM |
| Fitting the supplied roof felt and any trims | Treating or weatherproofing the timber |
| Securing the shed to the base | Removing and disposing of an old shed |
| A basic tidy of the work area | Fitting shelving, guttering, a water butt or electrics |
Confirm whether the base is included, as a shed assembled on an inadequate foundation will not last.
Can You Do It Yourself?
Most flat-pack sheds are designed for self-assembly, and a small shed can be built by two people over an afternoon with basic tools. Doing it yourself saves the labour cost, and the instructions are usually straightforward.
The catches are the base, size and getting it square. Preparing a firm, level base is the hard part — and the part that determines whether the shed lasts — involving digging, compacting hardcore and laying slabs or a pad. A shed built out of square, or on ground that isn't level, ends up with jamming doors, gaps that let in water, and a floor that rots early. Larger sheds are heavy and awkward for two amateurs to lift and hold in place. For a big shed, a difficult base, or if you simply want it built right first time, a professional installer prepares the ground properly and assembles it square and weatherproof.
How To Save Money On Shed Installation
- Choose the right size — buy for what you need rather than the largest shed on the forecourt.
- Prepare a good base once so the shed lasts and you avoid early repairs or replacement.
- Upgrade the roof covering to shingles or EPDM to avoid repeat re-felting costs.
- Clear the site and remove the old shed yourself if you can, to cut labour and disposal.
- Treat the timber regularly after installation to extend its life cheaply.
- Get a couple of quotes and confirm whether the base and old-shed removal are included.
How To Hire A Good Shed Installer
Choose an installer who will prepare or check the base rather than simply bolting a shed onto poor ground, as the base is what makes it last. Confirm they're insured, ask whether base preparation, an upgraded roof and old-shed removal are included, and check they'll square and secure the structure properly. Read recent reviews and get the scope and price in writing.
With Fantastic Services, you get vetted, insured installers who can prepare the base, assemble the shed square and weatherproof, and carry out repairs such as re-felting and panel replacement — with transparent pricing and online booking.

Frequently Asked Questions
How Much Does Shed Installation Cost?
Assembly labour costs £200–£600 depending on the shed size, on top of the shed unit (£150–£1,500+) and a base (£150–£600). London and the South East add roughly 20–30% to labour. A small 6×4 shed all-in (excluding base) runs around £300–£650.
Do You Need A Base For A Shed?
Yes — a firm, level, free-draining base is essential. Paving slabs, a concrete pad or a plastic base grid over compacted hardcore all work. A shed set straight onto grass or uneven ground shifts, jams and rots years earlier than one on a proper base.
Do You Need Planning Permission For A Shed?
Usually not. Most sheds fall under permitted development if they're single-storey, within height limits (around 2.5 m near a boundary), don't cover more than half the garden, and aren't forward of the house. Listed buildings and conservation areas have stricter rules — check with your council.
How Long Does Shed Assembly Take?
A small shed takes 2–4 hours to assemble; a large or complex shed can take most of a day, often with two people. Preparing a base beforehand adds time but is done before assembly day.
Can You Assemble A Shed Yourself?
A small flat-pack shed is a realistic two-person job with basic tools. The difficulty is preparing a level base and keeping the structure square — get either wrong and doors jam and the floor rots. Larger sheds and difficult bases are best left to a professional.
How Much Does It Cost To Re-Felt A Shed Roof?
Re-covering a shed roof costs £250–£450 for a durable finish such as felt shingles or EPDM rubber, less for basic felt. A hard-wearing covering costs more upfront but avoids re-felting every few years.
How Much Does Shed Repair Cost?
Common repairs — replacing rotten panels or floorboards, re-hanging a door, re-felting the roof or fixing a base — typically run £100–£500 depending on the extent. Catching rot and leaks early keeps repairs cheap and avoids full replacement.
