Metal garage prices in the UK run from a few hundred pounds for a flat-pack tin shed to £30,000+ for a large insulated steel building — and most advertised prices sit somewhere dishonest in between: a headline figure that excludes the base, the door, delivery or installation. Here’s how the market really prices out in 2026, what the cheap end actually buys, and what a genuinely all-in figure looks like.
The three price bands for metal garages
Almost everything sold as a “metal garage” in the UK falls into one of three bands:
- £500–£3,000: flat-pack kits. Thin galvanised sheet, self-assembly, no base, no real door, minimal warranty. Fine for a lawnmower; not a garage in any meaningful sense. This band is where “metal garage” horror stories come from.
- £8,000–£20,000: engineered steel garages, installed. A structural steel frame, profiled cladding, a proper sectional door, professional installation on an engineered base. This is the band where a metal garage becomes a genuine alternative to brick. VeltHaven’s steel range starts at £9,995 fully installed, including the automated insulated sectional door.
- £26,000–£40,000+: insulated steel garages. 100mm insulated panels, glazing options, a building you can heat and actually live in — gym, workshop, studio. Ours start at £26,950 installed. The steel vs insulated comparison explains who should spend the difference.
Metal garage prices at a glance (2026)
| Type | Typical installed price | What you get |
|---|---|---|
| Flat-pack kit | £500–£3,000 (supply only) | Thin sheet, self-assembly, no base or real door |
| Engineered steel garage | £8,000–£20,000 | Structural frame, sectional door, installed on an engineered base |
| Insulated steel garage | £26,000–£40,000+ | 100mm insulated panels — a building you can heat and use year-round |
VeltHaven prices within those bands: steel from £9,995 and insulated from £26,950, both all-in — building, automated insulated door, delivery, installation and VAT.
Why advertised prices are hard to compare
Two “£9,000 metal garages” can be £6,000 apart once really priced. Before comparing anything, ask what the figure includes:
- The base. A concrete base for a single garage commonly costs thousands if quoted separately — and a steel building is only as good as what it’s anchored to. (See how we handle foundations.)
- The door. Some suppliers price the shell and sell the door as an extra — on a garage. An insulated sectional door alone is a four-figure item.
- Delivery and installation. “Supply only” means you’re project-managing trades yourself. Installed prices that exclude delivery are quietly regional.
- VAT. Trade-facing suppliers habitually quote ex-VAT. Add 20% before comparing.
Our position is simpler: the price you see is all-in — building, automated insulated door, delivery, installation and VAT — and it’s shown live online as you configure, so there’s no quote to wait for and no surprise at the end.
What moves the price up or down
- Size. The single biggest factor. Whether you need a single or double roughly frames the budget band before anything else.
- Insulated or not. The step from steel to insulated is the step from “secure storage” to “usable room” — it’s the biggest single upgrade decision. (Full comparison.)
- Roof style and height. Apex, pent and lean-to options change steel content and appearance.
- Extras with their own value: EV charging, electrics, resin flooring — worth pricing as line items, not mysteries.
Metal garage price FAQs
How much does a single metal garage cost in the UK?
For an engineered, installed steel single garage with a proper door, realistic 2026 pricing starts around £9,000–£12,000 all-in. Our range starts at £9,995 installed. Sub-£3,000 “single garages” are kit sheds — a different product.
How much is a double metal garage?
Broadly the mid-teens and up for steel, and from the high-£20,000s insulated, depending on size and spec. The honest answer for your exact size is the configurator — it prices your configuration live in a couple of minutes.
Are metal garages cheaper than brick?
Yes, substantially, for comparable secure floor area — and installed in days rather than built over weeks. We’ve priced the comparison out in steel-frame vs brick or concrete.
Is a cheap metal garage kit ever the right buy?
If you need weatherproof storage for garden kit and nothing more, a kit does a job. If you’re storing a car, tools worth stealing, or anything you’d miss — the door, frame and installation are what you’re actually paying for in the next band up. Our guide to whether metal garages are any good covers how to tell the difference.
The bottom line
Metal garage prices only make sense once every figure is all-in. Realistically: kits under £3,000, engineered steel garages from around £10,000 installed, insulated garages from around £27,000 — and any comparison done on headline prices without the base, door, installation and VAT is a comparison of fictions.
