Driveway gate planning permission in Hertfordshire.
What the rules actually say, how each Hertfordshire council applies them, and when a gate installation will or will not need planning permission.What the rules actually say, how each Hertfordshire council applies them, and when a gate installation will or will not need planning permission.
Hertfordshire Planning Is Not One Rulebook. It Is Ten.
Ten district and borough councils share planning authority across Hertfordshire. Each has its own local plan, its own conservation areas, its own supplementary guidance on boundary treatments, and its own appetite for pre-application engagement. A gate that passes without objection in one borough can face five conditions in the next, even when the design is identical.
On top of the council layer, Hertfordshire carries some of the densest planning designations of any English county. The Chilterns National Landscape (formerly AONB) covers the western districts. Green Belt covers the overwhelming majority of the rural land. Conservation areas exist in every market town from St Albans to Royston. A substantial stock of listed buildings across the older settlements brings a separate consents regime.
This page gives you the four rules that apply everywhere, then links to detailed guidance for each of the five Hertfordshire planning regions. For most projects, using an installer who knows the local council personally is worth more than any amount of reading - the firms in our network handle planning engagement as part of the service.



This page does not replace formal advice
Everything here summarises general planning law and typical local practice. It is not formal pre-application advice from your council. For any project with cost at stake, verify with the council planning portal for your specific address before committing to a design or signing a contract.
The Four Rules That Apply Everywhere
These apply regardless of which Hertfordshire council you sit in. Start here before looking at local rules.
Gates fronting a highway used by vehicles must not exceed 1 metre in height without planning permission.
This is the headline rule most homeowners encounter. Any gate taller than 1 metre that opens onto a road used by cars requires a householder planning application.
Gates not fronting a highway can be up to 2 metres without planning permission.
If the gate opens onto a private drive, alley, or rear boundary away from a vehicle road, the permitted height rises to 2 metres.
Conservation areas, listed buildings, and article 4 directions remove permitted development rights.
In any of these cases the height allowances above do not apply and planning permission is almost always required. Always check the council planning map before committing to a design.
Automation does not itself trigger planning permission.
Motorising an existing gate that already complies with height rules does not normally require a separate application, though BS EN 12453 safety compliance is a separate legal obligation under CE / UKCA rules.
Planning Guidance by Hertfordshire Region
Hertfordshire is made up of ten local planning authorities grouped here into five regions. Select your area for the councils, conservation controls, and local sensitivities that apply.

Read planning rulesWhen Planning Engagement Is Genuinely Needed
Not every gate project needs a planning application. But these four scenarios almost always do, and the cost of getting it wrong is disproportionate.
Property in a conservation area
Permitted development rights are usually restricted. Most conservation areas in Hertfordshire require planning consent for any gate facing a highway, regardless of height.
Listed building or in its curtilage
Separate listed building consent is needed for boundary works. The distinction between "within the curtilage" and "separate" is often contested - get formal clarification before specifying anything.
Chilterns National Landscape (formerly AONB)
Material, height, and design scrutiny is substantially stricter. Natural timber in simple profiles passes most readily. Ornate wrought iron often does not.
Any gate over 1 metre next to a highway
This is the permitted development cut-off. Above 1 metre adjoining a highway triggers a planning application regardless of designation.
Let an Installer Who Knows Your Council Handle It
Every installer in our Hertfordshire network regularly engages with their local planning authorities. They know which officers sign off quickly, which designs the department tends to accept, and when a pre-application enquiry is worth the effort. Free site survey and planning review included.
