Everything You Need Before You Buy.
Four essential guides covering UK planning permissions, precise measuring, foundation requirements, and how to care for your structure across every season.
Most pergola installations in England fall under Permitted Development rights — meaning no planning application is required. However, specific rules govern size, position, and property type. Understanding these before you measure saves time, money, and frustration.
Permitted Development — The Basics
Under UK Permitted Development rights, garden structures including pergolas are generally allowed without a formal planning application, provided they meet certain conditions. These rights apply to houses — not flats, maisonettes, or listed buildings.
If your home has had its Permitted Development rights removed — sometimes done on new builds or in conservation areas — you will need to apply for planning permission regardless of the structure's size. Check your title deeds or contact your local planning authority to confirm.
The 2.5m Boundary Rule
If any part of your pergola falls within 2 metres of a property boundary, the maximum allowable height is 2.5 metres. This is one of the most commonly misunderstood rules — it applies to the eaves height, not the ridge height.
Within 2m of a boundary
More than 2m from all boundaries
Our standard pergola heights range from 2.2m to 3.2m depending on configuration. If you are close to a boundary, declare your intended height clearly in your suitability assessment so we can advise on compliant options.
The 50% Site Coverage Rule
Under Permitted Development, the total area of outbuildings and extensions (including your pergola) must not exceed 50% of the total garden area around the original house. The "original house" is defined as the property as it stood on 1 July 1948 — or as built, if built after that date.
Covered pergola structures count toward this figure. Open-sided structures with no defined roof may be treated differently by some local authorities — confirm with your LPA if your site coverage is marginal.
Lawful Development Certificates (LDC)
A Lawful Development Certificate is a formal document from your local planning authority confirming that your proposed structure is lawful under Permitted Development. It is not required by law — but it protects you when selling your property and provides legal certainty.

Listed Buildings & Conservation Areas
If your property is a listed building or sits within a conservation area, Permitted Development rights may be significantly restricted or removed entirely. Any alteration — including a garden structure — may require Listed Building Consent or Conservation Area Consent. Always consult your local planning authority before proceeding.
Our sister brand, Plan Pros, specialises in pre-application planning advice and can advise on LDC applications, conservation area constraints, and listed building consent requirements before you commit to a purchase.
Front Elevations
Permitted Development rights do not apply to structures built forward of the principal elevation (front) of the original house, or to the side of the house where it faces a highway. If your intended position is at the front or side of your property adjacent to a road, a full planning application is likely required.
