How Long Does Planning Permission Take? 2026 UK Guide

If you are planning an extension, a loft conversion or a new build, the first question is usually the same: how long does planning permission take? The honest answer for England in 2026 is eight weeks for most householder and minor applications and thirteen weeks for major schemes – but those are statutory targets measured from the day your application is validated, not from the day you submit it. Real-world timelines are often longer once validation, consultation, requests for extra information and committee dates are added. This guide sets out the official periods, the latest government data on how quickly councils are actually deciding, what changed on 31 October 2026, and practical ways to keep your application moving.

Key takeaways

• The statutory determination period in England is 8 weeks for householder and other non-major applications, 13 weeks for major development and 16 weeks where an Environmental Impact Assessment is required.
• The clock only starts the day after a valid application (all documents plus the fee) is received, so allow another one to two weeks for validation.
• Government figures for April to June 2026 show 92% of householder applications were decided within 8 weeks or an agreed extended period – but only 58% of “other” applications met the strict 8-week limit.
• From 31 October 2026 the National Scheme of Delegation means householder and minor applications must be decided by planning officers, not committees, which should remove one common source of delay.
• If the council takes longer than 16 weeks (non-major) or 26 weeks (major) without an agreed extension, you are entitled to a refund of the application fee under the Planning Guarantee.
• Most permissions last three years; if you have not started work by then, the permission lapses.

How long does planning permission take in the UK?

In England, a local planning authority should decide a householder or minor application within eight weeks of validation and a major application within thirteen weeks (sixteen weeks for EIA development). Councils can agree a longer period with you in writing. In practice, simple householder schemes typically take eight to twelve weeks from submission to decision.

Those periods are set by Article 34 of the Town and Country Planning (Development Management Procedure) (England) Order 2015. The period begins “on the day immediately following that on which the application is received” – and an application only counts as received once the forms, the required plans and documents and the correct fee have all been lodged. If a cheque bounces or a drawing is missing, the clock does not start.

Statutory planning timescales at a glance (England, 2026)

The “typical” column is an indicative range that varies by council and by scheme. Scotland and Wales run on similar principles: local developments in Scotland should be decided within two months and householder applications in Wales within eight weeks. The statistics and legislation in the rest of this article relate to England.

What the latest government data says about real decision times

The Ministry of Housing, Communities and Local Government (MHCLG) publishes quarterly statistics on planning applications. The most recent release, Planning applications in England: April to June 2026 (published 24 September 2026), shows:

• District-level authorities received 78,700 applications in the quarter, down 2% on a year earlier, and decided 74,500.
• 88% of decisions were approvals; for householder applications the approval rate was 91%.
• 92% of householder applications were decided within 8 weeks or an agreed extended period.
• Only 58% of “other” applications (which include householder schemes) were decided within the strict statutory 8 weeks, down 4 percentage points year on year. For minor applications the figure was 39%, and just 19% of majors met the 13-week limit without an extension.
• In the year to June 2026, councils received 314,200 applications and 93% of householder decisions were made within 8 weeks or an agreed time.

The gap between those two measures is the key to understanding the question. Councils hit their headline targets largely by agreeing extensions of time with applicants. If you are asked to sign one, it often means the officer wants more time to negotiate changes rather than refuse – but it also means your eight weeks may become twelve or sixteen.

The planning application timeline, stage by stage

1. Pre-application advice (optional: 4–8 weeks)

Many councils offer paid pre-application advice. Responses typically take four to six weeks, so it adds time up front, but it can prevent a refusal later. Our guide to pre-application versus full planning permission explains when it is worth the fee.

2. Preparing drawings and supporting documents (1–4 weeks)

Scaled existing and proposed plans, elevations, a location plan with a red-line boundary and any required reports (heritage, flood risk, trees, ecology) must match the council’s local validation list. A measured survey of the existing building is the foundation for accurate drawings.

3. Submission and validation (1–2 weeks)

Applications are normally submitted through the Planning Portal. The council checks the submission against its validation requirements and, if anything is missing, writes to you – and the statutory clock does not start until it is fixed.

4. Publicity and consultation (minimum 21 days)

Neighbours are notified and a site notice or press notice may be posted. Statutory consultees such as the highways authority, the Environment Agency or a parish council are given 21 days to respond.

5. Officer assessment and negotiation (2–6 weeks)

The case officer visits the site, reviews consultation responses and assesses the proposal against the local plan and national policy. Requests for amended drawings or additional information at this stage typically add two to four weeks each.

6. Decision

Most applications are decided by officers under delegated powers. Where a scheme goes to planning committee, waiting for the next meeting date can add several weeks – which is why the rule change below matters.

What changed on 31 October 2026: the National Scheme of Delegation

One of the biggest procedural changes in years took effect on 31 October 2026. The Town and Country Planning (Discharge of Local Planning Authority Functions) (England) Regulations 2026 (SI 2026/854) introduce a national scheme of delegation that replaces each council’s own rules on which applications go to committee.

• Must be decided by officers: householder applications, minor residential schemes of one to nine homes on sites under 0.5 hectares, minor commercial development, discharge of conditions, prior approval applications, non-material amendments and lawful development certificates.
• Exceptions that can still reach committee: retrospective applications under section 73A, applications linked to a listed building consent application, and applications made by or on behalf of the council itself.
• Larger schemes are presumed to be decided by officers unless a nominated councillor and a nominated officer both agree the case raises a significant planning issue.
• Ward councillor “call-ins” and automatic referral triggered by a set number of objections no longer apply, and planning committees are capped at 13 members.

For homeowners the practical effect is straightforward: a well-prepared extension or loft application should no longer be held over for a committee date simply because a neighbour has objected. That should bring more householder decisions inside the eight-week window. National Park authorities and the Broads Authority are excluded from the scheme.

Why planning permission takes longer than eight weeks

• Invalid or incomplete submissions: a missing block plan, the wrong scale or an unpaid fee are among the most common causes of delay.
• Designated areas: applications in a conservation area, affecting a listed building or in the Green Belt attract extra consultees and scrutiny.
• Consultee objections: highways, drainage or heritage concerns often require amended drawings.
• Officer workload: many planning departments carry heavy case loads, which makes the eight-week target difficult to hit.
• Section 106 agreements: on major schemes, drafting the legal agreement after a resolution to grant can add three to six months.
• Extensions of time: agreeing one keeps the council’s statistics healthy, but it is your timeline that stretches.

How to speed up a planning application

1. Check whether you need permission at all. Many extensions, lofts and outbuildings fall within permitted development rights. A lawful development certificate confirms this formally and costs half the normal fee for a proposed development.
2. Use the prior approval route for larger extensions. Single-storey rear extensions of up to 8 m (detached) or 6 m (other houses) can use the larger home extension scheme, where the council has 42 days to respond.
3. Get the drawings right first time. Commission a measured survey and have plans prepared against the council’s validation checklist.
4. Talk to the neighbours early. Objections rarely stop a compliant scheme but they can slow it down – and if the works affect a shared wall or involve excavation near a neighbour’s foundations, you will also need to serve notice under the Party Wall etc. Act 1996, which runs on its own timetable.
5. Respond to officer requests within days, not weeks. Every round of amendments adds review time.
6. Keep the clock honest. You do not have to agree an extension of time. If a council has not decided within the statutory period, you can appeal against non-determination.

What happens if the council takes too long?

Under the Planning Guarantee, if no decision has been made within 26 weeks for a major application or 16 weeks for any other application – and you have not agreed a longer period in writing – the council must refund your application fee. The rule is explained in paragraph 042 of the GOV.UK planning fees guidance. The 16-week refund applies to applications submitted on or after 6 December 2023.

You can also appeal to the Planning Inspectorate for non-determination once the statutory period has passed. Bear in mind that an appeal is rarely faster than waiting: the Planning Inspectorate’s statistical release of 30 July 2026 reported a median of 11.6 weeks from valid appeal to decision for householder appeals decided in June 2026, 17.1 weeks for other written-representation planning appeals and 18.6 weeks for hearings.

How much does a planning application cost in 2026?

Fees in England now rise automatically each April in line with the previous September’s CPI. From 1 April 2026 the householder fee for alterations or extensions to a single house is £548; discharging a householder condition costs £89; prior approval for a larger home extension is £249; and a lawful development certificate for a proposed use is half the equivalent planning fee. The current schedule is published by MHCLG as Planning fees: annual indexation from 1 April; always confirm the fee with your council or the Planning Portal before you submit. Fees are only one part of the budget – see our house extension cost guide for the full picture.

How long does planning permission last?

Under section 91 of the Town and Country Planning Act 1990, development must begin within three years of the date permission is granted in England (five years in Wales) unless the decision notice states otherwise. Any pre-commencement conditions must be formally discharged first; starting work without doing so can put the permission at risk. If you have built something without consent, our guide to retrospective planning permission explains the options.

After approval: the other clocks that start running

Planning permission does not authorise construction on its own. You will usually also need Building Regulations approval, a party wall award if the works affect a neighbouring owner, and possibly listed building consent or a licence to alter from a freeholder. Running these in parallel with the planning application – rather than one after another – is one of the most effective ways to shorten the overall programme, and a completion certificate at the end protects the value of the work when you sell.
