Planning Permission in Broxbourne
Non-Metropolitan District in East of England · Last updated April 2026
Broxbourne is a compact borough in south Hertfordshire, stretching along the Lee Valley from Waltham Cross in the south to Hoddesdon in the north. With extensive Green Belt covering much of the borough and the Lee Valley Regional Park along its eastern boundary, Broxbourne is significantly constrained for new development.
The borough's 6 conservation areas and 259 listed buildings reflect the historic market towns and villages that pre-date the 20th-century suburban growth. Waltham Cross takes its name from the Eleanor Cross — one of only three surviving medieval memorial crosses erected by Edward I.
Broxbourne manages planning applications for a borough undergoing significant regeneration, particularly around Brookfield and the town centres, while protecting its Green Belt and heritage assets.

Permitted development in Broxbourne
Broxbourne has no Article 4 directions, so most properties outside conservation areas retain full PD rights. The extensive Green Belt is the most significant constraint, covering the rural and semi-rural parts of the borough. The Lee Valley Regional Park along the eastern edge adds landscape considerations. In the urban areas of Cheshunt, Waltham Cross, and Hoddesdon, standard PD rights apply for most householder works.

Housing delivery in Broxbourne
Housing Delivery Test 2023 measurement | Source: MHCLG
Broxbourne delivered 1,042 homes against a requirement of 1,214 over the three-year measurement period, giving a Housing Delivery Test score of 86%. This is below the 95% threshold, which means Broxbourne must publish an action plan setting out how it intends to increase housing delivery. For homeowners, this is a positive signal — the council is under pressure to approve more housing, which can make planning officers more receptive to well-designed residential applications and extensions that add living space.
Lawful Development Certificates in Broxbourne
A Lawful Development Certificate (LDC) is formal confirmation from Broxbourne that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
Broxbourne decided 288 householder applications in the year ending september 2025. Their 8-week performance of 89.6% is below the national average of 93%, so LDC applications may take longer than the 8-week target. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Broxbourne
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Broxbourne's website. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
Broxbourne must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
