What to Expect Before You Buy

If you’re considering a pergola, one of the final questions before buying is often how installation works. Whether you’re planning a DIY installation or professional fitting, understanding the process helps avoid surprises and ensures your pergola performs as intended.

This guide explains how pergola installation works in the UK, what preparation is required, and what homeowners should consider before placing an order.

Do Pergolas Need Planning Permission in the UK?

In many cases, pergolas fall under permitted development, meaning planning permission is not required.

However, you may need permission if:

  • The pergola exceeds height limits

  • It is installed close to a boundary

  • The property is listed

  • The property is in a conservation area

If you’re unsure, it’s always best to check with your local planning authority before installation.

Where Can a Pergola Be Installed?

Pergolas can be installed on:

  • Patios

  • Concrete bases

  • Decking (with suitable reinforcement)

  • Purpose-built foundations

A solid, level base is essential for structural stability and long-term performance.

Ground Preparation for Pergola Installation

Before installation, the ground must be:

  • Level

  • Stable

  • Capable of supporting the pergola’s weight

Common preparation options include:

  • Existing concrete patio

  • New concrete pad

  • Paving slabs laid on a solid sub-base

Proper ground preparation ensures the pergola remains stable, drains correctly, and operates smoothly.

DIY Pergola Installation vs Professional Installation

DIY Pergola Installation

Some pergolas are designed to be installed by competent DIYers.

DIY installation may suit you if:

  • You’re comfortable with tools

  • You have at least two people available

  • The pergola is being installed on an existing solid base

DIY installation typically takes one to two days, depending on size and experience.

Professional Pergola Installation

Professional installation is often chosen for:

  • Larger pergolas

  • Complex installations

  • Peace of mind

Professional installers ensure:

  • Accurate alignment

  • Correct fixing

  • Proper drainage setup

Installation time is usually one day, depending on site conditions.

How Long Does Pergola Installation Take?

Installation times vary based on:

  • Pergola size

  • Ground preparation

  • Installation method

Typical timelines:

  • Small pergola: 4–6 hours

  • Medium pergola: 1 day

  • Large pergola: 1–2 days

Electrical Considerations (Lighting & Motorised Roofs)

If your pergola includes:

  • LED lighting

  • Motorised louvres

  • Integrated accessories

You may need a qualified electrician to connect power safely. Electrical work should always comply with UK regulations.

Anchoring and Stability

Aluminium pergolas are secured using:

  • Ground fixings

  • Anchor bolts

  • Structural plates

Correct anchoring is essential for:

  • Wind resistance

  • Long-term stability

  • Smooth roof operation

Maintenance After Installation

Once installed, aluminium pergolas require minimal maintenance:

  • Occasional cleaning

  • Clearing drainage channels

  • Checking fixings periodically

This low maintenance is one of the key reasons aluminium pergolas are popular in the UK.

Common Installation Mistakes to Avoid

  • Installing on an uneven base

  • Poor drainage planning

  • Incorrect fixing into weak surfaces

  • Rushing roof alignment

Avoiding these mistakes helps ensure reliable long-term performance.
