Planning Permission in Wellingborough
Local Planning Authority in England · Last updated April 2026
Wellingborough was replaced by North Northamptonshire in 2021 as part of local government reorganisation. Planning applications in this area are now handled by North Northamptonshire.
View North Northamptonshire planning authority pageWellingborough is a market town and former borough in Northamptonshire, now administered by North Northamptonshire Council (formed April 2021). The area has 10 conservation areas, 529 listed buildings (11 Grade I), and 2 Article 4 directions. Wellingborough Town Centre conservation area is on Historic England's Heritage at Risk Register, making heritage-sensitive development a priority.
The area is undergoing transformational growth through two major sustainable urban extensions: Stanton Cross (Wellingborough East) delivering 3,650 homes with £500 million investment and 6,000-7,000 jobs, and Glenvale Park (Wellingborough North) with over 1,000 additional homes in Phase 2. Planning decisions are guided by the North Northamptonshire Joint Core Strategy (2016) and the Plan for the Borough of Wellingborough (adopted February 2019) — the first Part 2 local plan adopted in Northamptonshire.
Three neighbourhood plans have been adopted (Earls Barton, Irchester/Knuston/Little Irchester, and Ecton). Chester House Estate — a £14.5 million heritage site opened in 2021 demonstrating 10,000+ years of human activity — and the famous Anglo-Saxon tower at All Saints' Church, Earls Barton (c.970 AD) are among the area's most significant heritage assets. Pre-application advice costs £180 (desktop assessment) or £380 (with site visit).

Permitted development in Welling
Permitted development rights in the Wellingborough area are shaped by 10 conservation areas and 529 listed buildings. Properties within conservation areas face restrictions on demolition, cladding, extensions, and external alterations. An Article 4 direction in Wellingborough Town Centre (since 2011) covers properties on Broad Green, Castle Road, Midland Road, and surrounding streets, restricting certain external changes. The town centre conservation area is on Historic England's Heritage at Risk Register, making sympathetic development particularly important. All Saints' Church, Earls Barton features one of England's finest Anglo-Saxon towers (c.970 AD, Grade I) — works near or affecting Grade I buildings require particular sensitivity.
What Welling expects from your project
Design in the Wellingborough area must respond to the Nene Valley character — a landscape of ironstone villages and river meadows. The two major SUEs (Stanton Cross and Glenvale Park) have master plans and design codes ensuring high-quality placemaking. Chester House Estate (Grade II listed, £14.5 million investment, opened 2021) demonstrates best practice in heritage-led regeneration, housing the Northamptonshire Archaeological Resource Centre with 20,000+ boxes of archaeological finds. Wellingborough station on the Midland Main Line (now electrified) connects to London St Pancras in approximately one hour, making the area attractive for commuter-focused development.
Local Plan: North Northamptonshire Joint Core Strategy
Wellingborough Borough Council was dissolved in April 2021 and merged with Corby, East Northamptonshire and Kettering to form North Northamptonshire unitary authority. Wellingborough's planning was covered by the North Northamptonshire Joint Core Strategy (adopted 2016), which supported its role as one of Northamptonshire's growth towns.
Emerging / replacement plan
North Northamptonshire Council is preparing a new Local Plan. A Regulation 18 consultation ran in 2022–2023, with a Regulation 19 plan anticipated in 2025.
Conservation areas in Welling
10 designated conservation areas
Wellingborough's 10 conservation areas range from the historic town centre (Heritage at Risk) to surrounding ironstone villages. Earls Barton conservation area protects the setting of the internationally significant Anglo-Saxon tower at All Saints' Church (c.970 AD, Grade I). Finedon conservation area covers a distinctive estate village. Ecton has associations with Benjamin Franklin (his paternal ancestors came from the village). The area's 11 Grade I listed buildings include All Hallows Church (c.1160, the oldest building in Wellingborough), and the remains of Croyland Abbey grange. Wellingborough's boot and shoe making heritage is reflected in the built character of the town centre.

Lawful Development Certificates in Welling
A Lawful Development Certificate (LDC) is formal confirmation from Welling 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.
Welling decided 162 householder applications in the year ending september 2025. Their 8-week performance of 91.2% 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 Welling
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Welling'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
Welling 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.
