How Much Does A Steel Building Cost? [2024 Guide]


“How much will my steel building cost me?”

This is one of the first questions anyone in the market for a steel building will ask.

We’ve answered this question hundreds of times over and it’s the first question we get asked with every prospective steel building buyer conversations.

We get it.

Price – whilst not the only consideration – is a pretty important one!

The price of your steel building often dictates what type of building you get, what options you go for and what accessories you choose. You need to develop an initial budget and plan for your building and the long-term ownership costs that will arise.

It’s tough to answer the “how much does a steel building cost” question right away because steel buildings have so many variables and options that impact the price. For example, size, colour, groundwork alterations, doors, windows, gutters and lots of other facts all play a part in the final price.

At Vanguard Steel Buildings, we strive to make choosing your steel building as effortless as possible and so in this article, I will do my best to offer some realistic price ranges, based on real-world examples right now (in 2024).

Please bear in mind that all prices are only estimates based on averages. Prices can and often do vary based on a wide range of factors, such as, you know… a pandemic!

How much does a steel building cost?

Most steel buildings will cost between £5,000 and £75,000 + VAT in 2024. This price includes the cost of designing, supplying the steel and erecting it.

As with any major project, this price range can vary dramatically based on several factors. Below I will outline the different factors that can affect the cost of a steel building so you can more accurately determine how much your steel building project will cost.

Factors that affect the cost of a steel building

There are a number of factors that impact the cost of your steel building project. These factors range from the ones you’d expect – such as location and size – down to little things you might not have considered yet such as specific design elements.

In this section, I’ll run through the most important price factors. Please note that not all of these factors determine our price at Vanguard Steel Buildings. Our philosophy at Vanguard is to provide you with all the information you need to make an informed decision. These are indicative of what you might expect in the wider marketplace.

Size and Dimensions

First up and perhaps the most obvious pricing factor: the size and dimensions of your project. In simple terms, the larger the project, the more it’s going to cost for obvious reasons. However, that’s not a hard and fast rule, as a small project with lots of additional extras could cost more than a larger project.

Steel buildings are broken into “bay sizes”. A bay is the area between 2 portal frame columns. Sometimes the building will require varying bay sizes to accommodate a certain door configuration. Generally, equal bay sizes will be cheaper than irregular ones.

There are standard sizes in the steel building industry, starting at 3m wide and 7m long and going up to 23m wide and 60m long. In the steel building industry, when discussing height we refer to “the height to eaves”. Our height to eaves is taken from the slab to the top of the eaves beams. The eaves beam is behind the gutter. What we would refer to as the apex, ridge or high eaves on a mono pitch building. Is the highest point of the building.

Of course, it’s possible to get larger sizes than that, but then there are additional factors to take into consideration which is generally best discussed with an engineer.


Secondly the cost of materials. There are a number of factors which impact the cost of the raw materials. Things such as COVID lockdowns and wars certainly don’t help. These costs sadly get passed down to the consumer eventually.

At Vanguard we do our absolute best to absorb as many of the added costs as possible to keep the costs low for our customers.

Location and landscaping

Location can have a large impact on the cost of your steel building. This generally doesn’t impact on price of the project, only the delivery costs. If your project is in the middle of the UK, the price to get the steel to the site will be less than if the steel building was somewhere remote – like the northern or western islands.

And so, your delivery costs may increase. It’s also important to note that costs will increase if construction equipment needs to be transported to the build site.

Similarly, the landscape where you want your steel building to be erected will have an impact on cost – mostly on the preparation work required – which can either be done by yourself or by a landscaper. If you have even land and a base already installed, your project will cost less than land that requires grading, tree removal or excavation for example.

Customisation Options

Most of the steel buildings you see dotted around the country will have standard dark green or grey cladding, a roller door at the front and roof lights on them.

But there are hundreds of different customisation options you can choose from when you come to design your steel building – all of which can impact the price. Below is an example of some of the customised choices you can have:

  • Colours – standard colours are often more cost-effective, while custom or premium colours may come at a higher price. Some manufacturers offer a limited selection of standard colours, and if you opt for a non-standard colour, it might involve a longer production time and higher costs.
  • Aesthetics – aesthetics play an important role in the cost of a steel building. You can add certain architectural elements, change the colour of certain parts of the building (eg. a different trim colour to the main cladding), you can add on gutters (and choose certain colours) etc.
  • Windows – Most projects will have roof windows (10% of the roof area is standard). But you can also add windows to the sides of your building. The type, size, and number of windows you choose will affect the cost. Larger windows, especially those designed for energy efficiency, tend to be pricier. Speciality windows, like tinted or insulated glass, can also increase costs.
  • Doors – Most projects will have a roller door and a walk-in door. But you can have whatever you like. Overhead doors, for example, are more expensive than standard walk-in doors. Additional features like insulation, windows in doors, or electronic door openers can add to the overall cost.
  • Cladding – The cladding material you select, such as steel panels or insulated panels will influence the cost. Insulated panels, for example, provide better climate control but are generally more expensive.
  • Roof style – The roof style you choose, whether it’s a gable, hip, or flat roof, will impact costs. Complex roof designs are more expensive due to increased engineering and construction requirements.
  • Building style – Typically you have 2 options. A ridge building is a building with a slope on each side of the ridge line. Or a mono pitch building, which has a single slope with a high eaves and low eaves.

Labour and Installation

The final cost, once you’ve prepared the land, designed and ordered your building is the labour and installation costs. Once your steel building arrives on site, you can choose to erect the building yourself to save money, work with your own contractor or some suppliers will also offer an erection service.

As we’ve previously mentioned, there are many factors that determine the price of your steel building. The best and most accurate way to determine the price of your project is to speak to a design specialist.

At Vanguard we’ll happily work with you – whether you have a set budget or not – to design the perfect building for you.
