How Much Does a Carport Cost in the UK? Single, Double and Triple Prices
A timber carport is one of the more variable purchases in the outdoor building category. Two structures with similar dimensions can still end up thousands of pounds apart once timber grade, roof type, post thickness, base preparation and installation are factored in. The headline figure is rarely the figure that matters most.
This guide explains what timber carports realistically cost in the UK in 2026, how single, double and triple layouts compare, and which items are most often missing from the first quote. The aim is to help you compare options honestly rather than by the most attractive starting price.
The short answer
- A single timber carport in the UK often lands around £2,000–£5,500 installed, depending on specification and site conditions.
- A double timber carport usually sits around £4,500–£10,000 installed, with triple layouts commonly reaching £8,000–£15,000 or more.
- The largest cost differences usually come from timber quality, roof finish, post thickness, base work and whether installation is included.
- A full new concrete base can add roughly £1,500–£3,000+ on its own, especially once excavation, drainage and reinforcement are involved.
- The most useful way to compare quotes is not by the starting price, but by what is actually included.
A short scope note: this article focuses on timber carports in the UK. Steel-framed and lighter polycarbonate-roof structures often sit in a different pricing bracket and are not the main comparison here. The ranges below are editorial benchmark estimates for realistic domestic projects rather than fixed supplier quotes.

UK carport prices at a glance
| Carport type | Typical footprint | Supply-only | Installed, all in | What it usually suits |
|---|---|---|---|---|
| Single (budget softwood) | Around 3 × 5 m | £900–£2,200 | £2,000–£3,500 | One car, straightforward driveway, lighter specification |
| Single (mid-range softwood) | Around 3 × 5 m | £2,000–£4,000 | £3,500–£5,500 | Daily use, stronger build, better longevity |
| Double (mid-range softwood) | Around 5.5–6 × 5–6 m | £4,000–£7,500 | £5,500–£10,000 | Two-car households, most common domestic layout |
| Triple (standard softwood) | Around 8.5–9 × 6 m | £6,500–£11,000 | £8,000–£15,000 | Larger households, van bay or overflow storage |
| Premium oak-framed | Varies | £10,000+ | £14,000–£30,000+ | Statement build, premium detailing, longer design life |
Use these ranges as a budgeting shape rather than a promise. Most of the movement comes from specification, the base and the real conditions on site.
What affects carport cost the most
A few factors do most of the work in shaping the final figure.
The main price drivers in plain English
Size and number of bays. The more bays you add, the more structure, roofing and labour is required. A double carport does not usually cost twice as much as a single because some structural elements are shared, but it still increases the budget meaningfully.
Timber grade and post thickness. This is where similar-looking carports often sit far apart in price. Lighter softwood sections are cheaper. Heavier timber, thicker posts and more substantial framing cost more, but generally feel sturdier and tend to age better.
Roof type. Felt is usually the cheapest option, but not the most durable. EPDM and shingles sit in the middle. Cedar shingles, tiled finishes and more architectural roof details push the figure up again.
Open vs partly enclosed design. A fully open carport is the simplest build. Add side cladding, a rear wall, a side store or integrated storage, and the cost rises quickly. At a certain point the project starts to overlap with garage-level pricing, which is where our guide to carport vs garage becomes useful.
Customisation. Standard sizes are usually the best value. Bespoke widths, taller posts for vans or motorhomes, attached lean-to formats and more detailed finishes all move the price upwards.
Site and access. A flat, open driveway is the easy case. Sloping sites, awkward access, hand-carry distances and tighter working conditions all add labour and sometimes equipment cost. This is one of the most underestimated parts of the budget.
Single carport costs
Single carports are the usual entry point for one-car households and narrow driveways.
Budget self-assembly kits can start around £900–£1,500, but they usually rely on lighter materials and simpler roofing. A more credible mid-range timber single carport often sits around £2,000–£4,000 for the structure itself, with a realistic installed total of roughly £2,500–£5,500 once base work and installation are included.
Most of the variation in this bracket comes from timber thickness, roof finish and how much of the project price has been left outside the headline figure.
Double carport costs
Double carports are the most common layout for UK households with two vehicles, and often the best value per vehicle in the range.
In realistic mid-range timber specifications, that usually means around £4,000–£7,500 for the structure and roughly £5,500–£10,000 installed once base, delivery and installation are included. Premium double carports, especially oak-framed or more heavily detailed versions, can sit well above that.
A double usually works out more efficiently than two separate singles because the central structure is shared. If the dimensions themselves are still an open question, our guide to what size carport do I need in the UK covers the practical sizing side before you commit to a budget.
Triple carport costs
Triple carports are the largest standard option and suit larger households, or buyers who want one bay for a van, motorhome or overflow storage.
A standard timber triple carport typically costs around £6,500–£11,000 for the structure, with installed totals usually landing between £8,000 and £15,000 depending on specification and site conditions. Premium builds go beyond that quite quickly.
The cost per bay is often a little lower than on a double because more of the structure is shared, but the headline total is high enough that it is worth being honest about whether all three bays are genuinely needed.
What is usually included and what is often extra
Where two quotes look far apart, the difference is often not in the carport itself but in what has or has not been included.
| Usually included | Often extra or assumed away |
|---|---|
| Posts, frame and roof structure | Base preparation or a full new concrete pad |
| Roof covering as specified | Installation labour on supply-only quotes |
| Standard fixings | Removal of an old carport, lean-to or paving |
| Basic delivery in straightforward cases | Restricted-access surcharges or long carry distances |
| Standard timber treatment on some ranges | Guttering, lighting, electrics and EV charging provision |
| Core structure price | Upgraded roofing, cladding, storage features and sometimes VAT |
This is why a quote that looks cheaper at first glance is not always cheaper in the end. For the broader pattern of how project costs expand beyond the headline product price, the garden building cost breakdown is a useful companion read.
Base, delivery and installation costs
The base is one of the most important parts of the project and one of the easiest to underestimate. Even a well-made timber carport will not perform properly if it sits on poor ground or an uneven surface.
If there is already a sound, level hardstanding in place, preparation costs may be relatively modest. Where a full new concrete base is needed, the figure is usually much higher. As a broad UK guide, minor preparation on an existing surface may cost a few hundred pounds, but a new concrete pad for a single-bay carport often lands around £1,500–£3,000, with larger double or triple bases costing more again depending on excavation, reinforcement, drainage and access.
Installation varies with size, roof complexity and site conditions. A single carport on a flat driveway is straightforward and often sits in the £400–£800 bracket. A mid-sized build typically runs around £700–£1,200. A larger structure on a sloping site with awkward access can push beyond £1,500.

Self-assembly vs professional installation
Self-assembly carport kits can look attractive on paper and may appear £1,000–£2,500 cheaper than an installed equivalent. Whether that saving is real depends on the project.
DIY tends to work when the buyer has genuine construction experience, proper tools, help on hand and a straightforward site with a prepared base already in place. It becomes much less convincing on larger structures, awkward ground, roof pitches that need careful setting out, or anything approaching a double or triple bay.
For many residential buyers, especially once the brief moves beyond a basic single-bay shelter, supplied-and-fitted is the more honest comparison.
Planning and sizing notes
For many houses in England, a carport can fall within permitted development if it meets the usual rules on height, position and site coverage. Scotland, Wales and Northern Ireland work under different planning systems, so local rules should always be checked separately. Conservation areas, listed properties, Article 4 directions and some newer estate restrictions can also change the position.
If you need the planning detail itself, our guide to planning permission for a carport in the UK covers the practical issues separately. If the main uncertainty is footprint rather than planning, the guide to what size carport do I need in the UK is the more useful next read.
How to compare quotes properly
The single most useful step before committing is to ask every supplier the same short list of questions. Price gaps that look large on the headline often shrink or reverse once the answers are lined up.
- Is this price supply-only or installed?
- What timber grade and post sizes are included?
- What roof material is included, and is it a basic or upgraded finish?
- Does the quote assume an existing hardstanding, or a full new base?
- Is delivery to my postcode included?
- What site access conditions are assumed?
- Are guttering, cladding, lighting or storage standard or optional?
- Is VAT included?
A useful rule of thumb is to take the structure price and add roughly 25–40% for the real project cost around it: base work, delivery, installation and a sensible contingency. On larger or more bespoke builds, the gap can be wider.
Final takeaway
Carport prices in the UK depend less on the category name — single, double or triple — and more on specification, site conditions and what is actually included in the quote. In 2026, most realistic timber carport projects sit somewhere between £3,500 and £10,000 all in, with smaller builds below that and premium or triple-bay projects above.
The useful step before asking for quotes is not chasing the lowest number. It is being clear about what the structure genuinely needs to do, then asking suppliers to quote against the same brief. Once the base, delivery, installation and roofing are all on the table, the comparison becomes much more honest.
FAQ
How much does a timber carport cost in the UK in 2026?
As a broad guide, single timber carports typically land around £2,000–£5,500 installed, doubles around £4,500–£10,000, and triples around £8,000–£15,000. Premium oak-framed or more heavily detailed builds sit above those ranges.
Why do similar-looking carports vary so much in price?
Most of the variation sits in timber grade and post thickness, roof material, whether installation is included, and what the quote assumes about the site. Two carports with the same footprint can be built to very different standards.
Is a double carport better value than two singles?
In almost all cases, yes. A double shares central posts and roof structure, which usually makes the cost per bay lower than specifying two separate singles.
What cost is most often missed on the first quote?
Base preparation is the most common omission. Many prices assume a level, ready-to-use surface is already in place. Delivery adjustments, removal of an existing structure, guttering, electrics and VAT are the other items most often left outside the headline figure.
How much does a concrete base for a carport cost?
If a suitable hardstanding is already in place, costs may be relatively modest. Where a full new concrete base is required, a single-bay pad often lands around £1,500–£3,000, with larger double or triple bases costing more depending on excavation, reinforcement, drainage and site access.
Is a self-assembly carport actually cheaper?
Sometimes, for smaller carports on simple sites with genuine DIY experience and a prepared base. On larger or more awkward projects, the saving can disappear quickly once tools, time, hired equipment and mistakes are factored in.
Does planning permission affect carport cost?
Not directly in most domestic cases. For many houses in England, modest carports can fall within permitted development, although Scotland, Wales and Northern Ireland follow different planning systems. Where planning input is needed, the application itself is usually a modest extra, but design changes can affect the structure price.
Is a carport cheaper than a garage?
Almost always. A carport is an open or partly open structure with far less material and labour than a fully enclosed garage. The better comparison is not only price, but what you genuinely need the structure to do in daily use.
