How Much Does It Cost to Build a Pergola in the UK?
(2025 Pricing Guide)

If you're considering transforming your garden or outdoor space, a pergola is one of the most stylish and practical upgrades you can make. But how much does it really cost to build a pergola in the UK? The answer depends on several factors — including the type of pergola, materials used, features like motorised roofs or LED lighting, and whether you choose a standard kit or a fully bespoke, luxury structure.

In this guide, we break down real pergola costs in the UK for 2025, explain what influences the price, and help you understand what to look for (and what to avoid) when making a decision.

Average Pergola Prices in the UK (2025)

💡 At Casa Pergola, our standard aluminium pergolas with electric louvres and LED lighting start from £3,500, while custom builds typically begin from £7,000+, depending on size and configuration.

Key Factors That Affect Pergola Costs

Size & Dimensions

• A small 3×3 m pergola will naturally cost less than a larger 6×4 m structure.

• Custom sizes also increase cost due to fabrication and shipping.

Materials Used

• Timber pergolas may look traditional, but they require regular maintenance.

• Aluminium offers a sleek, modern finish, and it’s more durable — especially powder-coated finishes in colours like RAL 7016 anthracite.

Roof Type

• Manual or fixed roofs cost less.

• Electric louvred roofs with remote control systems add premium value and comfort.

Add‑ons & Features

• Integrated LED lighting (usually built into the frame)

• Electric zip blinds for wind and sun protection

• Sliding glass doors or full glass walls for year‑round use

• Rain sensors and drainage systems

Installation & Foundations

• Installation costs depend on access, groundworks, and materials.

• Many projects require concrete pads or reinforced footings, which add to the total price.

Beware of Cheap Pergola Kits

A common mistake is comparing a bespoke aluminium structure to a £999 timber pergola from a DIY store. These cheaper kits:

• Often require significant self‑assembly

• May not survive harsh UK weather

• Come without features like lighting, drainage, or automation

• Can rust, warp, or degrade within 1–2 years

At Casa Pergola, we build permanent, architectural‑grade installations, not flat‑pack kits. It’s a completely different level of quality and finish — and the difference is clear once installed.

Is It Worth Investing in a High‑End Pergola?

Absolutely — especially if you're upgrading your garden, creating an outdoor dining or entertainment space, or adding value to your property. A well‑built pergola:

• Extends your living space outdoors

• Adds serious kerb appeal

• Can be enjoyed all year round with the right features (like blinds and heaters)

What’s the Cost of a Fully Installed Pergola?

If you want a “ready to enjoy” pergola with full installation, the starting price (including ground prep, delivery, and fitting) is typically:

• From £5,000+ for standard models (3×3 m electric roof with lighting)

• From £9,000+ for larger custom builds with glass walls and zip blinds

Every project is unique. We recommend requesting a quote so we can advise based on your space and what you'd like to achieve.
