UK Garden Pergola Cost Guide 2026

If you’re comparing quotes for a pergola and wondering why one installer says £1,200 while another is closer to £6,000, you’re not alone. In the UK, pergola prices vary a lot depending on material, size, whether it’s attached or free-standing, and what sort of base or extras you need.

How Much Does a Garden Pergola Cost in the UK?

A typical UK garden pergola costs £900–2,500 for a simple timber kit, £1,800–4,500 for aluminium, and £4,000–10,000+ for bespoke builds. Most homeowners spend £1,500–5,000 once labour, foundations and finishing extras are included, especially if the pergola sits over a patio or needs a built base.

What Affects the Price of a Pergola?

The biggest cost driver is material. Pressure-treated timber is usually the cheapest option, while powder-coated aluminium costs more but needs less upkeep and often lasts longer. Bespoke hardwood or steel-framed pergolas sit at the top end because they involve more design time, fabrication and installation skill.

Size matters too. A compact 2m x 2m pergola can often be supplied and installed for under £2,000, but a larger 4m x 3m structure with posts, roof slats and integrated lighting may easily reach £5,000–8,000. If you want a solid roof, retractable canopy or louvred system, expect the price to jump again.

Site conditions can quietly add to the bill. A pergola on an existing level patio is simpler than one placed on sloping ground, loose soil or lawn. If your garden needs levelling first, the base costs more. For a useful comparison on ground prep, see How Much Does Garden Levelling Cost in 2026?

Another factor is whether the pergola is attached to the house or free-standing. Wall-fixed designs sometimes need extra brackets, resin anchors and waterproof detailing around rendered walls or brickwork, which can overlap with other trades linked to Fencing & Walls and masonry work. Free-standing models are often easier to price, but they usually need stronger post foundations.

Location and access also affect pricing. A pergola supply-only kit can be cheaper if you have a straightforward driveway drop-off, but if installers need to carry materials through a narrow side gate or over delicate paving, labour can rise. In some London and South East postcodes, expect labour to be 10–20% higher than the national average.

Average Price Breakdown by Material and Build Type

Timber pergolas remain popular because they look natural and suit most UK gardens. Pressure-treated softwood kits usually cost £500–1,500 supplied, with installed prices more often landing at £1,200–3,000 depending on size and finish. Timber works well if you already have other Garden Buildings such as a summerhouse or shed and want a softer, traditional look.

Aluminium pergolas are a step up in cost but a big improvement in durability and maintenance. Expect £1,200–3,500 for supply-only on a basic frame, or £2,500–6,000 installed for a sleek domestic system. If you want a louvred roof, hidden drainage or integrated LED lighting, the project can move into the £5,000–10,000 range. Aluminium is especially appealing for modern patios and paved seating areas.

Bespoke pergolas are where prices vary the most. A custom timber pergola built to fit awkward boundaries, wrap around a corner, or match existing timber cladding may cost £3,500–7,500. Custom aluminium or steel structures, especially those designed as outdoor dining shelters or hot tub covers, can range from £6,000 to £15,000+.

Here’s a practical example: a homeowner in Manchester wants a 3m x 3m treated timber pergola over an existing block-paved patio. A typical quote might split roughly as follows: £850 for materials, £900 for labour, £150 for delivery and fixings, and £250 for post shoes and concrete pads. The total would be around £2,150. If the same customer upgraded to aluminium with a louvred roof, the quote could quickly rise to £5,500–7,000.

If your pergola is being added as part of a wider outdoor refresh alongside new paving, it’s worth checking the relative costs of the hardstanding itself. Our Garden paving cost in the UK: 2026 guide can help you decide whether to budget for slabs, porcelain or block paving before choosing the pergola style.

Optional extras can also change the overall figure. Side screens, privacy slats, outdoor heaters, planting troughs, roller blinds and festoon lighting may each add £100–1,000+, depending on the quality level. If the pergola is intended as a true outdoor room, these extras matter almost as much as the frame itself.

Labour, Foundations and Installation Costs

Labour for pergola installation typically costs £400–1,500 for a straightforward domestic job, but can rise to £2,000+ for large bespoke builds. Many installers charge a day rate of around £250–400 for a two-person team, with more complex systems taking one to three days to complete.

Foundations are a major hidden cost if the ground isn’t ready. For light timber pergolas, contractors may use concrete pad foundations or galvanised post shoes fixed into a slab. That might add £150–500. For heavier aluminium or bespoke structures, stronger footings or small concrete plinths may cost £500–1,200 depending on soil and access.

If the installation is going onto a new patio, the sub-base and paving need to be considered together. A pergola is only as good as the ground underneath it, which is why many installers prefer to work alongside patio teams rather than build on soft or uneven ground. This is especially true when the pergola is part of a wider Patios & Paving project.

There can also be extra charges for removing old structures, trimming overhanging roots, or getting rid of a rotten timber frame before the new pergola goes in. If you’re clearing space first, our Garden clearance cost in the UK: 2026 price guide is a useful reference point.

Delivery is another line item that people often overlook. Flat-pack kits are usually cheaper to transport, but large pre-assembled panels, heavy aluminium beams or bespoke steelwork may require specialist delivery and more than one person to unload. Expect delivery costs of £50–250 for standard kits and more for custom orders.

How to Save Money and Get Better Value

The easiest way to save is to choose the simplest structure that still does the job. A well-made pressure-treated timber pergola often gives the best value for most UK gardens, especially if you already have a suitable patio or paved base. If you want style without constant maintenance, a mid-range aluminium frame is often a smarter long-term buy than a cheap timber kit that needs regular treatment.

Buying supply-only can work if you’re confident with assembly and already have a level, solid base. But if you’re not experienced, the savings can disappear quickly if posts aren’t square or the structure isn’t anchored properly. In wet or windy parts of the UK, a poorly fixed pergola can move, twist or loosen over time.

It’s also worth bundling work together. If you’re already booking Garden Services for patio cleaning, fence repairs or border work, ask whether the contractor can combine the pergola install with other jobs. Some firms will offer a better day rate if they can fill gaps in the schedule, particularly if they are already on site for other garden improvements.

Another good value rule: spend more on the parts you cannot easily change later. That usually means the frame, posts and foundations. You can upgrade accessories over time — adding blinds, climbing plants or lighting later is usually cheaper than rebuilding a weak structure. For timber pergolas, choosing good-quality fixings and proper preservative treatment is also money well spent.

Be cautious with very cheap online kits. A low headline price can look attractive, but some budget options use thin timber, light-duty brackets or poor corrosion resistance. In exposed coastal areas or gardens with little shelter, that can shorten the life of the pergola and lead to extra repair costs within a few years.

If you want to keep the project tidy and cost-effective, consider the wider garden layout before ordering. A pergola placed too close to a boundary may create privacy issues or cast unwanted shade, while one positioned awkwardly on the patio can make the whole area feel cramped. In many cases, the best value comes from getting the design right first, then sizing the pergola to suit the space rather than forcing a larger build into a tight corner.

To get the best result, compare at least three written quotes and make sure each one clearly lists materials, labour, foundations, delivery, waste removal and any extras such as lighting or screens. Look for contractors who have proven experience with Garden Buildings and outdoor structural work, use proper fixings for UK weather, and are happy to explain exactly how the pergola will be anchored to your patio or base.
