Planning Permission in Warrington
Unitary Authority in North West · Last updated April 2026
Warrington is a unitary authority in the North West of England, designated as a New Town in 1968 and now one of the most economically successful growth centres outside London. The borough straddles the River Mersey and sits at the intersection of major motorway networks (M6, M62, M56), giving it exceptional connectivity. Warrington has 378 listed buildings (including 6 Grade I), 16 conservation areas, 14 scheduled monuments (including the Roman settlement at Wilderspool), and significant Green Belt covering approximately 57% of the borough.
Planning in Warrington is governed by the Adopted Local Plan 2021/22-2038/39 (adopted December 2023), which replaces the earlier Core Strategy (2014). The new Local Plan includes controversial Green Belt releases of approximately 580 hectares (5% of total Green Belt) for housing and employment, including the South East Warrington Urban Extension (2,400 homes) and Fiddlers Ferry power station redevelopment (860+ homes plus 130,000 sqm employment). A new HMO Article 4 direction for the Central 6 wards was made in September 2025 and, if confirmed, will come into force in September 2026. Warrington does not charge CIL, relying instead on Section 106 agreements.
With a planning approval rate of 76% (below the national average of 86.9%), a Housing Delivery Test score of 145% (well above threshold), and 96.1% of householder applications determined on time, Warrington has a mixed planning record. The borough's distinctive character combines its New Town legacy (Birchwood, Oakwood Gate), historic villages (Lymm, Grappenhall, Stockton Heath), and major employment sites including Omega (the largest mixed-use development in the North West at 226 hectares on the former RAF Burtonwood airbase) and Birchwood Park. One neighbourhood plan has been made (Appleton Thorn, 2017) with three more in preparation.

Permitted development in Warrington
Permitted development rights in Warrington are affected by several important local factors. Properties within any of the 16 conservation areas have reduced PD rights for extensions, roof alterations, and certain external changes. Green Belt restrictions cover approximately 57% of the borough, meaning extensions must not constitute disproportionate additions to the original building. From 25 September 2026 (if confirmed), a new Article 4 direction will remove PD rights for converting dwelling houses (C3) to small HMOs (C4) in the Central 6 wards — Orford, Poplars and Hulme, Fairfield and Howley, Latchford East, Latchford West, and Bewsey and Whitecross. The council's House Extensions SPD provides detailed guidance on what is and isn't permitted development. The council advises that pre-application enquiries should be submitted before designing proposals, and warns that negotiation during the application process will be infrequent for householder proposals.
What Warrington expects from your project
Design policy in Warrington is set through the Adopted Local Plan 2021/22-2038/39 (December 2023), supplemented by the Warrington Design Guide SPD, Environmental Protection SPD, and Planning Obligations SPD (all adopted/updated July 2024). Warrington's character varies enormously — from the medieval town centre around the Grade I listed Town Hall and its famous Golden Gates, through the New Town residential areas of Birchwood and Oakwood Gate (planned from 1968), to the affluent villages of Lymm, Grappenhall, and Stockton Heath south of the Ship Canal, and rural areas with scattered farmsteads. The Town Centre Masterplan (2020) sets a 20-year vision for transformation including the Circular Parklands green ring, waterfront development, and converting former retail space to homes. The Central 6 Masterplan guides a Town Deal programme worth over £22 million for regeneration of the inner wards. Major design considerations include the Omega development's impact on surrounding villages and the integration of large-scale sites like Fiddlers Ferry.
Local Plan: Warrington Local Plan Core Strategy 2006–2027
Warrington adopted its Core Strategy in July 2014. Warrington is a New Town with a strong economic base in logistics and professional services, and the plan supports its role as a regional hub for growth in the north-west. Significant housing and employment growth is planned, including the Omega Strategic Development Site.
Emerging / replacement plan
Warrington is preparing a new Local Plan. A Regulation 18 consultation ran in 2020 and Regulation 19 consultation ran in 2022, with submission anticipated in 2025 and adoption targeted for 2026.
76% approval rate
Warrington's planning approval rate is below the national average of 86.9%. If your project needs planning permission, consider pre-application advice before submitting — it significantly reduces refusal risk.
Conservation areas in Warrington
16 designated conservation areas
Warrington has 16 designated conservation areas protecting the historic character of distinctive neighbourhoods across the borough. These include the historic village centres of Lymm (designated 1971, the earliest in Warrington), Grappenhall Village (1974), Walton Village (1977), and Thelwall Village (1977); two areas in Stockton Heath (London Road and Grappenhall Road, and Ackers Road and Marlborough Crescent); the Victoria Road and York Drive area of Grappenhall; and several town centre conservation areas including Buttermarket Street (1972), Town Hall (1972), Palmyra Square (1974), Bewsey Street (1976), Bridge Street (1980), Church Street (1984), and Winwick Street (1999). The Greenalls Brewery conservation area (2001) and Culcheth (Newchurch) (1993) complete the list. Conservation area appraisals have been completed for six town centre areas. The borough also has 378 listed buildings, including Grade I listed Warrington Town Hall (formerly Bank Hall, built 1750) with its famous Golden Gates, and the Sankey Viaduct — the world's earliest major railway viaduct (1830).

Planning application statistics
Year ending September 2025 | Source: MHCLG planning application statistics
Warrington received 878 planning applications and decided 904 in the year ending September 2025. The approval rate of 76% is below the national average of 86.9%. Major applications are expected to be decided within 13 weeks, while householder and other non-major applications have an 8-week target. The “in time” figures include decisions made within agreed extensions of time.
Warrington's planning approval rate of 76% is notably below the national average of 86.9%, suggesting a more cautious approach to development proposals. The council made 904 planning decisions in the year to September 2025, with a delegation rate of 94.7%. Performance on timeliness is strong: 95.5% of major applications, 94.7% of minor, and 96.1% of householder applications were determined on time. The Housing Delivery Test result of 145% (2023 measurement, delivering 2,789 homes against 1,926 required) means no buffer or presumption applies, though the estimated 2024 result of 89% suggests delivery may be slowing. The Local Plan sets a housing requirement of 816 homes per year over an 18-year period (2021-2038). Major development activity is concentrated at Omega South (1,400 homes planned), the Fiddlers Ferry redevelopment (860+ homes approved May 2025), the South East Warrington Urban Extension (2,400 homes), and the Cockhedge town centre scheme (up to 900 homes).
If your project complies with permitted development rules, you don't need to worry about approval rates — a Lawful Development Certificate is a factual assessment, not a judgment call.

Warrington delivered 2,789 homes against a requirement of 1,926 over the three-year measurement period, giving a Housing Delivery Test score of 145%. This is above the 95% threshold, which means there are no government-imposed consequences for housing under-delivery.

Lawful Development Certificates in Warrington
A Lawful Development Certificate (LDC) is formal confirmation from Warrington 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.
Warrington decided 536 householder applications in the year ending september 2025. Their 8-week performance of 96.1% is above the national average of 93%, which suggests LDC applications are likely to be processed on time. LDC applications follow the same 8-week statutory determination period as householder planning applications.

You can apply for a Lawful Development Certificate through the Planning Portal or directly through Warrington'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
Warrington 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.
