Key Statutory Findings (2026/27)
Over half (55.4%) of England's 296 billing authorities are non-metropolitan Shire Districts (ONS prefix E07), where household planning and Council Tax billing are handled by the District/Borough Council, while highways, schools, and social care are administered by an upper-tier County Council (E10).
The remaining 154 billing authorities across England and Wales operate as single-tier municipalities: 63 English Unitary Authorities (E06), 36 Metropolitan Districts (E08), 33 London authorities (E09), and all 22 Welsh Unitary Councils (W06).
Under Article 34 of the DMPO 2015, Local Planning Authorities have a statutory deadline of 8 weeks to determine minor/householder planning applications, 13 weeks for major developments (10+ dwellings), and 16 weeks for EIA-accompanied applications.
In two-tier E07 Shire Districts, standard CON29 conveyancing enquiries require coordination between the District Council (planning, building control, environmental health) and the County Council (adopted highways under CON29 Q2.1 and Public Rights of Way).
Executive Analysis
One of the most frequent sources of delay in UK residential conveyancing and household administration is confusion between postal towns, two-tier district/county councils, and single-tier unitary authorities. A royal mail postcode address frequently names a postal town located in an entirely different administrative borough, and in 164 English non-metropolitan districts (ONS code prefix E07), local government statutory powers are legally divided between two separate councils.
Using the Office for National Statistics (ONS) Government Statistical Service (GSS) 9-character coding standard across all 318 English and Welsh billing authorities, our governance atlas maps the exact division of statutory responsibilities. In the 154 single-tier authorities—comprising 33 London Boroughs (E09), 36 Metropolitan Districts (E08), 63 English Unitary Authorities (E06), and 22 Welsh Unitary Councils (W06)—a single council acts as the Billing Authority, Local Planning Authority (LPA), Highway Authority, and Education Authority.
By contrast, across the 164 English Shire Districts (E07), the lower-tier District or Borough Council acts as the Local Planning Authority (determining householder extensions, Tree Preservation Orders, and Building Control) and the Council Tax Billing Authority, while the upper-tier County Council (E10) acts as the Highway Authority (holding the Definitive Map of Public Rights of Way and highway adoption records required for CON29 Question 2.1), Minerals & Waste Planning Authority, and Local Education Authority.

Ready-to-Cite Press Commentary
“Over 55% of English billing authorities are two-tier Shire Districts (ONS prefix E07) where planning permission and Council Tax are run by the District Council, while road adoption, footpaths, and school catchments are controlled by the County Council. Checking the exact 9-character ONS authority code by full postcode prevents homebuyers and applicants from contacting the wrong local authority department.”

Frequently Asked Questions
What do the ONS codes E06, E07, E08, E09, and W06 mean?
The Office for National Statistics (ONS) assigns a 9-character Government Statistical Service (GSS) code to every UK local authority. The 3-character prefix identifies its legal tier: E06 denotes an English Unitary Authority (63 councils), E07 denotes an English Two-Tier Non-Metropolitan Shire District (164 councils), E08 denotes an English Metropolitan District (36 councils), E09 denotes a London Borough or City of London (33 councils), and W06 denotes a Welsh Unitary Authority (22 councils).
What is the statutory time limit for a UK council to decide a planning application?
Under Article 34 of the Town and Country Planning (Development Management Procedure) (England) Order 2015, the statutory determination period is 8 weeks for minor and householder applications, 13 weeks for major development applications (such as 10 or more dwellings), and 16 weeks for applications subject to an Environmental Impact Assessment (EIA).
Statutory Diligence Guides & Legal Governance Framework
Statutory legal guidance covering BNG mandatory metrics, CIL charging liabilities, Class MA conversions, and overage clawback covenants.
What Are the Statutory Rules for Biodiversity Net Gain (BNG) in 2026?
In 2026, statutory Biodiversity Net Gain is mandatory for all major developments (since February 2024), small residential sites (since April 2024), and Nationally Significant Infrastructure Projects (NSIPs, mandated in 2026). Key statutory requirements include: (1) A legally binding minimum 10.0% net gain over pre-development baseline, (2) Submitting an approved Biodiversity Gain Plan before commencement of works, (3) Securing habitat enhancements for a minimum 30-year maintenance period via Section 106 agreements or Conservation Covenants, and (4) Registering off-site gains on Natural England's National Biodiversity Gain Site Register.
How Is CIL Charge Calculated in the UK? (Statutory Formula & Indexation)
Community Infrastructure Levy (CIL) is calculated using the statutory formula set out in Regulation 40 of the Community Infrastructure Levy Regulations 2010 (as amended): CIL Charge = (Gross Chargeable Area in m² × Adopted CIL Charging Schedule Rate £/m² × Indexation Factor for Planning Grant Year) ÷ Indexation Factor for Schedule Adoption Year. Chargeable area is calculated as the Net Additional Gross Internal Area (GIA), meaning the floorspace of existing permanent buildings demolished or converted can be deducted if they were in continuous lawful use for at least 6 months during the previous 3 years.
Class MA Permitted Development: 2024 & 2026 Floorspace Limit Abolition Rules
On 5 March 2024, the UK Government officially abolished the restrictive 1,500 square metre floorspace limit under Statutory Instrument 2024/241 (The Town and Country Planning General Permitted Development England Amendment Order 2024). Under current Class MA regulations, commercial Class E buildings of ANY size (including multi-storey office blocks, department stores, and large business parks) can be converted into residential C3 dwellings via prior approval, without requiring a full planning application, provided all statutory prior approval conditions (adequate natural light, NDSS space standards, contamination, flood risk, and transport) are satisfied.
How to Get Out of an Overage Clause in the UK: 4 Legal Strategies
To legally escape, discharge, or remove an overage clause on UK land: (1) Contractual Term Expiry: Wait out the agreed perpetuity period—once the contractual sunset date (typically 10 to 25 years) lapses, all clawback liabilities extinguish automatically, (2) Deed of Release Buyout: Negotiate a discounted lump-sum settlement with the overage beneficiary and execute a formal Deed of Release to cancel the Land Registry Form L restriction, (3) Exploit Drafting Defects: Challenge vague definitions of 'development' or positive covenants that fail to bind successors under the rule in Rhone v Stephens, or (4) Tailored Planning Consent: Apply for planning permissions that deliberately bypass the deed's narrow trigger definitions.
How Do You Calculate Statutory Biodiversity Net Gain (BNG) in the UK?
Biodiversity Net Gain (BNG) is calculated using the statutory Defra metric formula: Biodiversity Units = Baseline Habitat Area (hectares) × Habitat Distinctiveness (1 to 8) × Habitat Condition (1 to 3) × Strategic Significance (1.0 to 1.15). To secure planning permission under Schedule 7A of the Town and Country Planning Act 1990, developers must demonstrate that post-intervention units (on-site retained and enhanced habitats plus off-site units) equal at least 110% of the pre-development baseline score across each of the three mandatory unit types: area habitats, hedgerows, and watercourses.
CIL Rate per Square Metre Calculator Gov UK: Statutory Form Guide
The Gov.uk planning framework manages CIL through statutory Planning Portal forms rather than an online government calculation widget. To comply with statutory requirements: (1) Form 1 (CIL Additional Information) must accompany your initial planning application, detailing existing and proposed GIA in square metres, (2) Form 2 (Assumption of Liability) confirms who will pay the levy, (3) The council issues a statutory CIL Liability Notice upon granting permission, and (4) Crucially, Form 6 (Notice of Commencement) must be served on the council BEFORE any construction starts, or all surcharge penalties (up to £2,500) and loss of exemption rights occur.
Class MA Prior Approval: The Statutory 56-Day Deemed Approval Rule Explained
Under Paragraph W(11) of Schedule 2, Part 3 of the General Permitted Development Order 2015, the local planning authority has a strict statutory deadline of 56 calendar days (beginning on the day after the valid application was received) to determine a Class MA prior approval application. If the council fails to notify the applicant of its decision (grant, refuse, or formal written agreement to an extension of time) within that 56-day window, prior approval is legally deemed to be granted by operation of law, allowing the developer to proceed with the conversion.
Can You Buy Out an Overage Clause? Valuation & Release Deeds Guide
Yes. A landowner or developer can negotiate a buyout of an overage clause at any time by paying the beneficiary an agreed lump sum and executing a formal Deed of Release. The buyout value is determined using an RICS Red Book valuation model: the surveyor calculates the estimated future enhanced development value, applies the contractual clawback percentage (e.g. 30%), discounts the result for planning risk (e.g. 50% probability of planning grant) and the time value of money (discount rate of 8% to 12% per annum), and subtracts allowable development deductions. Once settled, Land Registry Form RX3 is submitted to cancel the restriction permanently.
