Hertfordshire presents one of the more complex planning landscapes for residential gate installations in England. The county contains two Areas of Outstanding Natural Beauty (the Chiltern Hills and the Green Belt villages), a substantial belt of Green Belt land along the M25 corridor through St Albans and Watford, ten separate district councils each with their own local plan policies, and conservation areas in towns and villages across the county from St Albans and Hertford to Harpenden and Shenley.
Permitted Development: The General Rule
Most residential driveway gates in Hertfordshire fall under permitted development and do not require a planning application. The general rule allows gates up to 2 metres in height that open inward onto the property. For gates adjacent to a classified road, the limit drops to 1 metre. These thresholds apply to the finished height of the gate measured from ground level at the point where it meets the road or pavement.

Chilterns AONB and Green Belt
Both AONBs carry specific planning sensitivity for residential development, including gates. The Chilterns AONB runs along the chalk hills from the Buckinghamshire border through St Albans, Wheathampstead, and onwards toward Hitchin. The Green Belt covers the southern part of the county including Berkhamsted, Much Hadham, Aldbury, and Braughing. Properties within either AONB should confirm the planning position before proceeding, as Article 4 Directions can remove permitted development rights.
Green Belt Along the M25 Corridor
The Metropolitan Green Belt extends into Hertfordshire through St Albans District and Watford Borough. Properties within this designation are subject to stricter controls on development including boundary treatments. While standard driveway gates generally remain within permitted development, Green Belt properties with Article 4 Directions should check with the relevant district council before proceeding.
Conservation Areas and Listed Buildings
St Albans, Hertford, Harpenden, Wheathampstead, and dozens of Hertfordshire villages have conservation area designations that affect what you can install at the property boundary. Listed buildings require separate listed building consent for any gate installation regardless of height. Hertfordshire has a particularly high density of medieval and Tudor listed properties in its historic centres, and an installer familiar with the county will know when consent is needed and how to design a gate that satisfies the conservation officer.
Twelve District Councils: Who to Ask
Hertfordshire County Council is not the planning authority for residential gates. Planning applications and pre-application enquiries go to the relevant district council: St Albans, Radlett and Malling, Harpenden, Welwyn Garden City, Watford, Gravesham, St Albans, Swale, Ashford, Hitchin and Hythe, Dover, or Thanet. Each district has its own local plan policies and supplementary guidance on boundary treatments. Your installer should know which district covers your property and what the local policy says.
