Pergola Installation Cost Explained: UK Prices for 2026
Pergola installation costs from £1,500 to £25,000+. Compare UK prices, labour, foundations, extras and what a complete quote should include.
Pergola installation costs in the UK typically range from £1,500 for a simple fitted timber structure to more than £25,000 for a large motorised aluminium pergola with screens, lighting and heating. As a simple domestic benchmark, Checkatrade estimates an average of about £2,500 for a standard supplied-and-installed pergola, with luxury builds around £10,000.
That £2,500 figure is useful for a conventional timber build, but it is not an average for every product sold as a pergola. A professionally installed aluminium or louvred system commonly falls between £5,000 and £12,000, while commercial-grade and heavily enclosed structures cost more.
All figures below are indicative market snapshots. Check whether a price is supply-only or installed: the final amount depends on the structure, roof, foundations, access, drainage and electrical work, so two pergolas with the same dimensions can have very different project costs.
Pergola installation costs at a glance
| Pergola type | Indicative supplied-and-installed cost | Typical scope |
|---|---|---|
| Simple timber pergola | £1,500–£4,500 | Open roof on prepared ground |
| Aluminium pergola with fixed roof | £4,000–£8,000 | Low-maintenance frame and fixed canopy |
| Manual louvred aluminium pergola | £6,000–£12,000 | Adjustable roof and integrated drainage |
| Motorised louvred pergola | £8,000–£16,000 | Powered roof, controls and commissioning |
| Premium pergola with screens and lighting | £12,000–£25,000+ | Made-to-measure structure with integrated extras |
These ranges cover broad UK market bands rather than a guaranteed quotation. Size, postcode, specification and site conditions all matter. See the main UK pergola cost guide for product-specific price tables and optional-extra ranges.
Pergola cost by size
Size helps with early budgeting, but it only works as a guide when the material and roof are broadly comparable. An open timber pergola can cost less than a smaller motorised aluminium system.
| Approximate size | Indicative cost | Important context |
|---|---|---|
| 10 × 10 ft | £600–£2,300 | Broad market range; specification and installation scope vary |
| 12 × 12 ft | Around £2,500 | Common benchmark for a standard supplied-and-installed pergola |
| Small, around 3 m × 3 m | £1,500–£3,000 | Typically a straightforward timber or basic freestanding build |
| Medium, around 4 m × 3 m | £2,500–£4,500 | Timber or entry-level structure without premium enclosure |
| Large domestic pergola | £4,000–£8,000+ | Roof, span and foundation requirements become more influential |
Checkatrade publishes the £600–£2,300 range for a 10 × 10 ft pergola and an average of about £2,500 for a 12 × 12 ft build. The metric size bands are broader budgeting ranges rather than like-for-like quotations. A 12 × 12 ft structure is approximately 3.7 × 3.7 m, so it should not be treated as identical to a 3 × 3 m model.
The practical rule is simple: cost usually rises with footprint, structural spans, material and roof complexity. Once louvres, motors, integrated drainage or side systems are added, product type becomes more important than area alone.
Price benchmarks by pergola type
| Pergola type | Indicative UK price | Price basis |
|---|---|---|
| Basic DIY timber kit | £400–£2,000 | Supply-only; quality and completeness vary |
| Standard pergola | Around £2,500 | Broad supplied-and-installed benchmark |
| Retractable-roof pergola | Around £4,000 | Common supply benchmark excluding labour |
| Manual-roof aluminium pergola | Roughly £2,500–£4,000 | Supply-only entry and mid-market systems |
| Electric-roof aluminium pergola | Roughly £3,500–£7,000 | Supply-only; size, motor and controls affect price |
| Bespoke luxury pergola | £7,000–£15,000+ | Often supply-only before foundations and extras |
The aluminium ranges overlap because the labels used by sellers are not standardised. Some “manual” products are simple opening-roof kits, while others use heavier structural sections, integrated gutters and higher-specification finishes. Treat the table as a way to set expectations, then check the exact model and inclusions.
A louvred roof normally sits towards the premium end because the blades, operating mechanism, seals and drainage require more engineering than an open frame. Automated systems add motors, controls and commissioning.
What does the installation itself cost?
It is difficult to separate installation labour from the structure because professional suppliers often quote one price for survey, supply and fitting. Checkatrade gives a typical builder rate of £250–£300 per day and estimates about £500 of labour for a standard one-to-two-day installation. Complex luxury builds can push labour towards £1,000 or more.
Those figures describe basic building labour, not the complete work involved in every specialist aluminium installation. A low assembly price may assume that the base is already level, suitable fixing points are available and no specialist access, drainage or electrical work is needed. A realistic installation budget may also need to cover:
- A site survey and final measurements
- Concrete pads, ground screws or base alterations
- Delivery and moving components into the garden
- Structural anchoring or wall fixing
- Roof drainage and rainwater routing
- Electrical connections for motors, lighting or heaters
- Testing, commissioning and waste removal
For this reason, compare complete project prices rather than trying to judge an installer by a labour-only figure.
Why commercial pergolas cost more
Commercial pergolas are generally larger, more heavily engineered and expected to cope with frequent use. Hospitality projects may also combine multiple bays, glass sides, blinds, lighting and heating, so their prices should not be compared with a basic domestic timber frame.
As one supplier snapshot, Express Pergolas lists the following starting prices for 4 m × 3 m systems:
| 4 m × 3 m system | Supplier price from |
|---|---|
| Manual blades | £8,400 |
| Tilting blades | £9,600 |
| Retractable blades | £13,800 |
These Express Pergolas figures include VAT but exclude installation, glass, blinds, foundations and other extras. They illustrate how far a premium engineered product can sit above the broad £2,500 domestic benchmark; they should not be treated as market-wide averages.
What a pergola installation quote should include
A useful written quote should make it clear what you are buying and what remains your responsibility. Look for:
- Dimensions and specification — footprint, height, post positions, material, finish and roof system.
- Survey and design — who confirms the measurements, ground conditions, drainage route and fixing points.
- Foundations — the type, number and size of pads or fixings, including any paving that must be lifted and reinstated.
- Delivery and assembly — whether unloading, access equipment and disposal of packaging are included.
- Drainage — gutters, downpipes and where water will discharge.
- Electrical work — cabling, isolation, controls and testing for motorised roofs, lights, heaters or screens.
- Finishing and handover — testing, cleaning, operating instructions and care information.
- VAT, warranty and exclusions — the final price, payment stages and anything specifically left out.
If one quotation is much cheaper, compare the scope line by line. It may exclude groundwork, power, delivery or VAT rather than represent the same installation for less money.
The main factors that change the price
Pergola material
Timber normally has the lowest entry cost and suits open-roof garden structures. Aluminium costs more but needs less routine treatment and supports fixed, louvred and motorised roof systems.
The material also changes the installation method. A simple timber frame and a large aluminium system with concealed gutters, motors and screens require different foundations, tolerances and skills. Our timber versus aluminium comparison covers the practical trade-offs.
Roof type
An open timber frame is simpler than a waterproof fixed roof. A louvred roof adds adjustable blades, seals, drainage and sometimes motors or weather sensors.
Roof complexity affects both supply price and fitting time. It also makes accurate levelling more important because the blades must close correctly and water must flow into the designed channels. For a closer comparison, see the available pergola roof options.
Size and structural spans
A larger footprint requires more material, but cost does not always rise in a perfectly straight line. Wide unsupported spans can require larger structural sections, extra posts or multiple roof bays.
Made-to-measure shapes, wraparound layouts and unusually tall structures also add design and installation work. Ask whether the quoted dimensions are outside-to-outside measurements and confirm how much usable covered space remains between the posts.
Foundations and the existing surface
The visible patio or decking does not necessarily provide a suitable structural base. Installers need to know what sits underneath it.
- Concrete or sound paving may accept suitable structural anchors.
- Porcelain paving needs careful drilling and may require slabs to be lifted.
- Decking usually needs reinforced framing or independent foundations below the boards.
- Soil or lawn normally needs concrete pads, piles, ground screws or another designed foundation.
- Sloping ground may require levelling, retaining work or a revised post arrangement.
Groundwork is one of the most common reasons an apparent kit bargain becomes a more expensive finished project.
Access and delivery
Long carries, narrow side passages, steps and raised gardens increase handling time. Large aluminium components may require additional labour or lifting equipment, while a crane or road restriction can affect the delivery plan.
Send photographs and access measurements early, but expect the installer to verify them before the order is finalised.
Attached versus freestanding
A freestanding pergola needs foundations for every post and may require power to be run across the garden. An attached pergola uses the house for support on one side, but the wall construction, waterproofing, door heights and rainwater route need careful assessment.
Neither arrangement is automatically cheaper. The best option depends on the proposed position and how readily the structure can be fixed and drained.
Typical costs for foundations and extras
The following ranges are indicative allowances. Product size, electrical routes and the amount of preparation can move them substantially.
| Item | Indicative additional cost |
|---|---|
| Concrete base or wider ground preparation | £1,500–£4,000 |
| Electrical connection | £300–£800 |
| Integrated LED lighting | £300–£1,200 |
| Heating | £500–£2,500 |
| Motorisation upgrade | £1,000–£3,000 |
| Rain or wind sensors | £200–£600 |
| Zip-track side screen | £1,500–£3,000 per side |
| Sliding glass wall | £3,000–£8,000+ per side |
Do not simply add every upper figure to the base price: installers package products differently, and some work may already be included. Use the table to identify which questions to ask.
Three example installation budgets
Basic timber seating pergola: around £2,000–£4,500
This might cover a modest open-roof timber structure on accessible, prepared ground. The budget rises if the design needs a solid roof, extensive staining, difficult access or new paving and foundations.
Mid-range louvred aluminium pergola: around £6,000–£12,000
This generally covers an aluminium frame with an adjustable roof and integrated drainage. Larger sizes, unusual colours, motorisation or difficult groundwork move the price towards or above the top of the band.
Premium outdoor room: around £12,000–£25,000+
A large motorised pergola with lighting, heating, side screens or sliding glass can become a substantial outdoor-living project. At this level, make sure the design coordinates the foundations, electrics, drainage, ventilation and all side systems from the beginning.
Is DIY installation cheaper?
DIY can reduce labour costs when you have a straightforward kit, a suitable base, the correct tools and enough competent helpers. It is less attractive when the project involves large components, wall fixings, concealed drainage, complex foundations or mains electrics.
Check the manufacturer’s installation requirements before choosing DIY. Incorrect anchoring, poor levelling or unauthorised electrical work may affect safety, roof performance and warranty cover.
Professional installation is most valuable when the installer takes responsibility for the complete specification rather than only assembling the frame. Compare the responsibilities and likely savings in our guide to pergola kits versus professional installation, then review the commercial pergola installation guide for the usual process from survey to handover.
How long does installation take?
Once the base and materials are ready, a straightforward pergola may take one to three days on site. A larger motorised structure with drainage, lighting and side screens may take two to five days or longer.
That is separate from the order lead time. Survey, manufacture and scheduling can extend the full project to several weeks. Read the detailed guide to pergola installation times when planning around landscaping or a particular event.
How to compare pergola quotes fairly
Give each installer the same information: approximate dimensions, photographs, access details, preferred material, roof type, extras and intended position. Then compare:
- The exact pergola model and dimensions
- Foundation and fixing method
- Drainage and electrical scope
- Delivery, equipment and waste removal
- Finish and optional extras
- Installation timescale and order lead time
- Structural, finish and motor warranties
- VAT, payment stages and exclusions
Price matters, but a vague low quote is difficult to compare with a detailed fixed specification. Resolve omissions before paying a deposit.
Setting a realistic budget
Begin with what the pergola needs to do, then allow for the whole installation rather than only the advertised structure. A basic open timber feature, a rain-covered dining area and a motorised outdoor room are different projects.
If planning restrictions may affect the size or position, check the pergola planning-permission guidance before committing to a non-refundable order.
Once you have likely dimensions and a specification, compare itemised prices from installers covering your area. BestPergola can help you request pergola installation quotes without obliging you to proceed.
