Planning Permission in East Hertfordshire
Non-Metropolitan District in East of England · Last updated April 2026
East Hertfordshire is a large, predominantly rural district covering the historic county town of Hertford, Bishop's Stortford, Ware, and Sawbridgeworth, along with dozens of villages. With 42 conservation areas, 3,019 listed buildings, and extensive Green Belt, the district is one of the most heritage-rich and constrained planning authorities in Hertfordshire.
The district has no Article 4 directions, but the combination of Green Belt, heritage density, and the high-value property market creates a complex planning environment for householder works. The 3,019 listed buildings represent one of the highest concentrations in the country.
East Hertfordshire's planning service manages significant demand driven by the affluent commuter towns and the Gilston Garden Town development to the south of the district.

Permitted development in East Hertfordshire
East Hertfordshire has no Article 4 directions, but with 42 conservation areas and extensive Green Belt, many properties face significant constraints. The Green Belt covers most of the countryside between the four main towns. Outside conservation areas and the Green Belt, standard PD rights apply. The district's 3,019 listed buildings mean that many properties — even outside conservation areas — require listed building consent for alterations.
What East Hertfordshire expects from your project
Local design guidance
Local Plan: East Herts District Plan
The East Herts District Plan was adopted in October 2018. It provides a comprehensive policy framework for the largely rural Hertfordshire district including the towns of Hertford, Bishop's Stortford and Ware. The plan allocates significant housing growth to serve London's commuter needs.
Emerging / replacement plan
East Herts is preparing a new Local Plan in response to the new NPPF. A Regulation 18 Issues consultation is anticipated in 2025.
42 conservation areas
East Hertfordshire has a high number of conservation areas. Check whether your property falls within one before starting any work — conservation area status significantly restricts what you can do without planning permission.
Conservation areas in East Hertfordshire
42 designated conservation areas
East Hertfordshire's 42 conservation areas protect the historic character of Hertford's medieval and Georgian core, Bishop's Stortford's town centre, Ware's Great Bed-famous High Street, and dozens of villages. Much Hadham, with its Bishop's Palace and exceptional collection of timber-framed buildings, is particularly notable. The conservation areas preserve the traditional Hertfordshire village character of flint-and-brick buildings, ancient churches, and rural settings.

Their 8-week performance of 97.8% is above the national average of 93%, which suggests LDC applications are likely to be processed on time.

- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
