Cost Breakdown of Prefab Cabins in the UK

In the realm of versatile and efficient construction solutions, prefab cabins have emerged as a game-changer for various industries such as construction, engineering, education, healthcare and events & hospitality.

Whether used as on-site offices, restrooms, or additional storage spaces, these modular buildings offer a cost-effective and time-efficient alternative to traditional construction. 

In this post, we will delve into the detailed cost breakdown of prefab cabins in the UK, exploring both upfront expenses and the long-term savings they bring to the table.

Upfront Expenses

1. Prefab Cabin Cost

The primary expense revolves around the cost of the prefab cabin itself. Prices can vary based on size, design, and features. On average, a basic prefab cabin in the UK can range from £15,000 to £40,000. Factors influencing costs include materials used, insulation, and customisations.

For us, our 2.4m x 1.4m prefab cabin starts at £4,135 + VAT and this includes two (2) windows, a lockable door and standard electrical package.

We have sizes ranging from this up to 6m in length which is available from £9,250 + VAT as a singular unit. Of course, as they are modular cabins, we can always add additional ones with ease.

2. Site Preparation

Before delivery and installation, it’s essential to prepare the site for the prefab cabin. Site preparation involves clearing, levelling, and potentially laying a foundation.

Costs for site preparation can vary but typically range from £2,000 to £5,000. You may find that you have the resource available on site to do this, so costs may actually come in lower.

3. Transportation and Installation

Transporting the prefab cabin to your site and installing it also contribute to upfront expenses. Depending on the distance, transportation costs can range from £1,000 to £3,000.

This is just a guide as we tend to use third party networks to deliver our products with the option of collection from our hub in Worcestershire to make things more cost effective.

If you are having the cabin delivered flat packed then installation costs, including labour, can vary based on the complexity of the setup and may range from £5,000 to £10,000. If you’re having the cabin delivered fully assembled by us, then this cost can be excluded.

4. Utilities Connection

Connecting the prefab cabin to utilities such as electricity, water, and sewage is another upfront cost. The expenses here can vary based on proximity to existing connections and the complexity of the installation, ranging from £2,000 to £5,000. You may also have to factor in on-going costs of powering and heating your cabin, so make sure not to forget this part!

Long-Term Savings

1. Energy Efficiency

Prefab cabins are designed with energy efficiency in mind. The insulation and modern construction materials used help maintain a comfortable interior temperature, reducing the need for excessive heating or cooling. This translates into long-term energy savings, contributing to a lower carbon footprint and reduced utility bills.

2. Durability and Low Maintenance

Prefab cabins are built to withstand various weather conditions and are often more durable than traditional structures. With minimal maintenance requirements, these cabins offer long-term savings on repair and upkeep costs.

We have a dedicated section on our Portable Cabins page which talks specifically about the maintenance and sustainability of portable office cabins.

3. Versatility and Future Expansion

The modular nature of prefab cabins allows for easy expansion or relocation as business needs evolve.

This versatility provides a significant advantage over traditional buildings, potentially saving costs associated with new construction or renovations.

Whilst there may be costs involved in adding more cabins to make a larger space, in the long run it’ll prove to be more cost-effective and potentially quicker too – no need for planning up to a certain square footage!


In conclusion, while the upfront expenses for prefab cabins in the UK may seem significant, the long-term savings and benefits they offer make them a wise investment. 

From energy efficiency to low maintenance, prefab cabins provide a cost-effective solution for businesses looking to expand or enhance their on-site facilities. Consider the value they bring to the table not just as an immediate expense but as a strategic investment in the future of your business.

For those seeking site cabins for sale and exploring prefab cabins in the UK, the upfront investment can pave the way for a resilient and efficient on-site solution.
