Thinking about adding a pergola to your garden?
A pergola is one of the most popular ways to create an outdoor living space, providing shade, style and a perfect area for relaxing or entertaining.
In 2026, the average cost of installing a pergola in the UK ranges from £1,500 to £6,000, depending on the size, materials and whether you choose a freestanding or attached design.
Premium aluminium pergolas with louvred roofs and integrated lighting can cost £10,000 or more.

What affects the cost?
Material
The material has the biggest impact on price.
Timber
Timber pergolas are usually the most affordable.
They offer a traditional appearance but require regular maintenance such as staining or painting to protect them from the weather.
Aluminium
Aluminium pergolas are more expensive but require very little maintenance.
Many homeowners choose aluminium because it won’t rot, warp or require regular treatment.
Steel
Steel pergolas are extremely durable but are generally more expensive and less common in residential gardens.
Size
The larger the pergola, the more materials and labour are required.
A small seating area may only need a 3m × 3m pergola, while a large outdoor dining space could require a much bigger structure.
Roof type
Pergolas can be supplied with:
- Open roof
- Polycarbonate roof
- Retractable canopy
- Fixed roof
- Motorised louvred roof
Motorised systems offer the most flexibility but are also the most expensive.
Ground preparation
Some gardens require:
- Levelling
- Concrete bases
- Patio alterations
- Decking modifications
- New paving
Ground preparation can add significantly to the overall project cost.
How long does installation take?
Most pergolas can be installed in 1–3 days.
Larger bespoke pergolas or those requiring extensive groundwork may take several days longer.
Do you need planning permission?
In many cases, no.
Pergolas are often covered by permitted development rights if they meet certain height and location requirements.
However, you may need permission if:
- You live in a listed building.
- Your property is in a conservation area.
- The pergola exceeds permitted height limits.
- It is positioned close to property boundaries.
Always check with your local planning authority if you’re unsure.
Timber vs aluminium
Choose timber if:
- You prefer a natural appearance.
- You’re working with a smaller budget.
- You don’t mind regular maintenance.
Choose aluminium if:
- You want minimal maintenance.
- You prefer a modern design.
- You want maximum durability.
- You plan to stay in the property long-term.
Hidden costs
Don’t forget to budget for:
- Groundworks
- Concrete footings
- Electrical installation for lighting
- Outdoor sockets
- Garden landscaping
- Furniture
- Heating
- Blinds or screens
- VAT
These extras can add several thousand pounds to the project.
How to save money
Install during quieter seasons
Some contractors offer better availability and pricing outside the busy spring and summer months.
Build on an existing patio
Installing a pergola over an existing patio usually reduces groundwork costs.
Compare several quotes
Always obtain at least three quotations.
Check whether each quote includes:
- Materials
- Installation
- Concrete footings
- Waste removal
- VAT
- Warranty
Choose the right size
Larger isn’t always better.
Choose a pergola that suits both your garden and how you’ll actually use the space.
Frequently Asked Questions
Is a pergola worth the money?
For many homeowners, yes.
A pergola creates additional outdoor living space and can make the garden more enjoyable throughout the year.
Does a pergola add value?
A well-designed pergola can improve kerb appeal and make outdoor spaces more attractive to buyers, although there’s no guaranteed increase in property value.
What’s cheaper: timber or aluminium?
Timber is generally cheaper to install, while aluminium usually costs more upfront but requires less maintenance over time.
Can a pergola be installed on decking?
Yes, provided the decking structure is strong enough to support it.
A professional installer can advise whether reinforcement is needed.
Final thoughts
For most UK homeowners, expect to budget between £1,500 and £6,000 for a professionally installed pergola.
Your final cost will depend on the material, size, roof design and any groundwork required.
If you’re looking for a low-maintenance option, aluminium is often the better long-term investment. If you’re working to a tighter budget, a timber pergola can still create a beautiful outdoor space at a lower cost.
