How much does a pergola cost? A complete pricing guide for 2025

How much does a pergola cost in the UK?

The average cost of a pergola in 2025 is about £2,500. But as you’d expect, prices vary, depending on the size and style of the pergola, the accessories you go for, and whether you choose to self-install or get the professionals on the case.

Shop around, and you’ll find basic pergolas as cheap as £500-600. And if you really want to splash the cash, you can pay £10,000 and over for a top of the range pergola with all the trimmings. If you’re wanting to build a unique pergola from scratch, you should expect your custom pergola cost to be several thousand pounds.

Here at Close The Deal, prices for our top quality aluminium pergolas range from £1784 for a 3m x 3m model, right up to £5739 for a 4m x 8m kingsize pergola.

Key factors that affect cost to build a pergola

Material type (aluminium, steel, polycarbonate and other materials)

Pergolas are usually constructed from wood or metal such as aluminium or steel. The material you choose will impact the price.

Wooden pergolas: These are often the least expensive option (£500-£1000), usually because they are less durable.

Steel pergolas are a heavyweight option, requiring strong, firm ground, and can cost around £1,500.

Powder coated aluminium pergolas usually cost from £1,750 upwards. Because they last so long and require little maintenance, people often find aluminium pergolas provide the best long term value for money. Some are available with polycarbonate roofs, a transparent material that’s 250 times stronger than glass and able to filter out the sun’s harmful UV rays.

Aluminium and steel combo pergolas: In most cases, the frame is made from aluminium and the roof louvres are steel. These are usually cheaper than full aluminium pergolas (starting from £1,000), because the galvanised steel isn’t as weather resistant as aluminium, so the roof is more likely to lose its waterproof seal more quickly.

Glass pergolas are an expensive, glamorous option, with prices ranging from about £2,000 to well over £10,000

Size and design of the pergola

The bigger the pergola you’re looking for, the more you can expect to pay. That stands to reason, as bigger pergolas require more materials.

3m wide x 3m long: These small pergolas are ideal for your patio or balcony. At Close The Deal, we sell these in aluminium for an average of £1784.

• 4m x 4m is a mid-size pergola, available from us in aluminium for an average of £3294.
• 4m x 8m is a kingsize pergola which costs an average of £5739 in aluminium from us.

Another variable that affects the price is the pergola style. 

Freestanding pergolas, which have 4 legs and can be placed in open spaces, tend to cost more than wall-mounted pergolas. These have only 2 legs as they are designed to attach to existing structures such as the back of your house.

Choosing a basic design pergola will also be cheaper than one with a more ornate, complicated design.

Pergolas with roofs

Many cheaper wooden pergolas simply have beams over the top and are ideal for training climbing plants to grow. 

If you want your pergola roof to have a more enclosed feel, you can choose from a retractable roof, a solid transparent polycarbonate or fibreglass roof, or a louvered roof with slats you can open and close.

The cost to build a pergola with roof is between £1,500 and £9,000. With so many options, such as manually or electrically controlled louvres, it’s difficult to pin down a precise price.

DIY installation vs professional installation

If you’re confident you can prepare the ground for your pergola and build it with the help of a friend or two, you’ll save money when compared to hiring professional installers.

Depending on the size of your pergola and complexity of your location, the average pergola installation cost UK customers can expect to pay is between £250 to £1,000.

Additional materials for pergola installation

Your pergola may require extra materials to ensure its sturdiness and safety. These could include:

• Footings (£10-£15 each)
• Reinforced concrete pads (prices vary)
• Additional brackets or fasteners for wall mounting (£300+)
• Anchors to increase wind resistance (£100-£200)

Pergola accessories

It’s likely you’ll want to add a few touches to personalise your pergola and make it feel more comfortable and homely. These will increase the pergola cost UK customers pay. Here are some typical prices:

• LED lighting – Strip lights for pergolas start from £300.
• Heaters – a broad range of heaters are available to keep you snug under your pergola. Prices start from £150 and can go into the thousands for ultra luxurious heat sources.
• Drop screens - these open and close down each side of your pergola, bringing a room-like cosiness to the space when you want privacy and shelter. Prices start from £415 on our website.
• Louvred side panels - install these on the sides of your pergola. They can be opened and closed and cost £500-£550 per panel - (3 will cover one side).
• Laser cut side panels – these permanent, decorative side panels will bring colour and design flair to your pergola. Prices for these vary between £180 and £230 per panel.
• Sliding louvered doors - give you a stylish way to get in and out of your pergola. The average price for these is around £1,650. It’s a similar price for sliding glass doors.
• Furnishings –it’s up to you what you put under your pergola – maybe a dining table and chairs, some recliners, a garden suite, a hot tub, a BBQ. All of these will be additional costs unless you have them already!

Installation of a pergola

Getting professionals to install your pergola will likely cost up to £500 per day depending on the size and complexity of the task.

Doing a DIY installation will likely cost nothing more than the price of a few cups of tea and some snacks to keep the friends who help you build your pergola kit refreshed.

A price worth paying

It’s also worth knowing that a pergola can significantly increase the value of your home. Lots of home buyers like the idea of having the extra outdoor space pergolas provide and are willing to pay extra for it.
