Average Concrete Shed Foundations Cost

What is a concrete shed foundation? It’s a level structure that lies under your shed, made of concrete, to keep your shed dry and away from the ground.

On average, the price for a concrete foundation for a garden shed in the UK ranges from £500 to £1,500 when putting both material and labour costs together.

For a small shed measuring 6ft by 4ft, you might pay between £500 and £750. Mid-sized sheds, such as those measuring 8ft by 6ft, could cost around £750 to £1,200.

Here’s a quick summary of shed foundation costs:

ItemCost Estimate
Small Shed Base (6’ x 4’ / 1.8m x 1.2m)£500 – £750
Medium Shed Base (8’ x 6’ / 2.4m x 1.8m)£750 – £1,200
Large Shed Base (12’ x 8’ / 3.6m x 2.4m)£1,000 – £1,500

You may be wondering why it differs so much.

Well, the cost of concrete shed foundations depends on these factors:

Size: Larger sheds require more materials and labour, increasing the cost.

Complexity: Intricate designs or uneven land may require additional work and materials.

Materials: The choice between ready-mix concrete or bagged mix affects cost.

Labour: Regional labour rates influence the overall expense, especially if hiring groundworkers.

Site Preparation: Clearing and levelling land adds to the initial costs before construction begins.

Although these are the average costs, it always pays off to get in touch with a groundworker about your specific job. Post your job on MyBuilder to connect with verified groundworker professionals near you and get their advice today.

Is A Concrete Shed Foundation Worth the Cost?

Concrete provides outstanding stability and long-term durability, ensuring your shed stays solid and secure for decades. Unlike timber or paving slab bases, a concrete foundation is highly resistant to pests, moisture, and ground movement, offering superior protection against the elements.

By opting for concrete, you’re not only creating a stable and weatherproof base but also safeguarding your shed’s structure. This stability means fewer worries about warping, rotting, or shifting over time.

In fact, a properly laid concrete foundation can extend the lifespan of your shed, reducing the risk of costly repairs or premature replacements. This could save you some money in the long run, too!

How Much Does A Professional Concrete Pourer Cost

Bringing in a professional to prepare and pour a concrete foundation for your shed is the best way to make sure the base is done properly and without hassle.

Labour rates for this kind of work can vary significantly based on the location and complexity of the project. On average, general labourers charge between £112 and £360 per day, while a groundworker may have an average day rate of £154/day.

Therefore, the total labour cost can range from £40 to £50 per m² for a shed base installation.

Note: The total labour time can be influenced by site-specific factors, such as soil conditions and accessibility, which can impact the overall duration and cost of the project. For example, if the soil is very wet, then it is more difficult to have a steady terrain to lay the concrete down on.

Different Types of Concrete Foundation and Their Costs

Choosing the right foundation helps ensure the stability and longevity of your shed. Consider your shed's size, design, and intended use when making your decision.

Here is a summary of different types of foundations and their costs:

Foundation TypeCost Range
Slab Foundation£500 - £1,500
Pier Foundation£600 - £1,800

Slab Foundation Benefits

Slab foundations are popular because they provide a solid, level base that is suitable for most garden sheds. This type of foundation is a single concrete pad that spreads the load evenly, minimising the risk of sinking or tilting over time. If you want to know more about foundation installations for a house, you can read this full cost guide on larger scale foundations for more information.

Pier Foundation Benefits

Pier foundations are ideal for uneven terrain or areas prone to flooding. They lift the shed off the ground, allowing air to circulate and reducing moisture accumulation. This option is particularly useful in gardens where soil conditions are more turbulent.

Top Tips to Save Money on Concrete Shed Foundations

When it comes to laying a concrete foundation for your shed, you don't have to spend a fortune.

Below are budget-friendly tips to help you manage costs effectively:

  • Purchase materials in bulk to benefit from lower prices.
  • Compare suppliers' prices to find the best deal on concrete and other essential materials.
  • Plan ahead to prevent delays and avoid unexpected expenses.
  • Consider off-peak times for construction, as some groundworkers offer discounts during slower periods.

FAQ: Common Questions Readers Ask About Concrete Foundations for Garden Sheds

What factors determine the overall cost of a concrete foundation for a garden shed?

The cost of a concrete foundation for a garden shed is influenced by several factors, including the size of the shed, the thickness and volume of concrete required, labour costs, and the geographic location of the project. Additionally, site preparation, such as clearing and levelling the ground, can also impact the overall expense.

How does the price of a concrete foundation for a shed compare to other types of foundations?

Concrete foundations are generally more expensive than alternatives like gravel or wooden foundations due to the durability and support they offer. While initial costs are higher, concrete can save money in the long run with fewer repairs and a longer lifespan.

What is the general process for constructing a concrete shed foundation?

This involves the following steps: Site Preparation, which includes clearing and levelling; Marking the Layout with stakes and string; Excavating the Area to the required depth; Assembling Formwork to outline the concrete area; Installing Reinforcement, such as steel mesh or rebar; Pouring and Levelling Concrete within the forms; and finally, Curing the Concrete for several days to achieve desired strength before use.

How can I estimate the budget needed for a concrete foundation under my garden shed?

To estimate the budget for a concrete foundation, start by determining the dimensions of your shed to calculate the volume of concrete required. Multiply this volume by the cost per cubic metre of concrete and remember to add labour and material costs, such as reinforcement and formwork materials.

Breeze block planter foundations in waterlogged clay corner

Luisa Volpe 20/05/2026 - 9.18 AM

Hi all, Looking for some advice on a build in a very waterlogged clay garden. We’ve already installed several French drains, which have helped overall, but one corner remains problematic. We’re planning to build a Mediterranean-style raised planter using breeze blocks in that area. We’ve excavated approx. 40 cm down x1mt area and the ground now feels much firmer (fork doesn’t penetrate easily anymore). Proposed build-up: - At base: existing clay subsoil - Lay non-woven geotextile membrane - Add 15 cm of 10–20 mm shingle for drainage For the structure itself: - Form a footing trench with wooden boards(approx. 30 cm wide, L-shaped around planter areas) Then another layer of geotextile - Fill with ~10 cm MOT Type 1 (compacted) - Then 15 cm concrete footing, potentially reinforced with rebar Additional constraint: There are existing concrete fence post footings (“concrete lumps”) in this area which support the fence posts. Questions: 1. Does this layered approach make sense for this type of ground, or am I overcomplicating it? 2. Is the double geotextile layer (below and above shingle) appropriate, or unnecessary? 3. Would you trust this as a stable base for a block planter, or should the footing go directly onto the subsoil/MOT without the shingle layer underneath? 4. Any better approach for dealing with the waterlogged clay in this situation? 5.What’s best practice for building on top of existing fence post concrete footings? OK to pour new concrete on to, or should there be a gap/isolation? Appreciate any input. I am keen to get this right before pouring concrete. Thanks!
