April 2026: No New Evidence Changes Appeal vs Resubmission in England

Homeowner weighing appeal and resubmission options

Resubmit when the refusal points to something fixable, such as missing reports or design details that can be adjusted. Appeal when the dispute is about planning judgement rather than facts, and your original application already had the full evidence behind it. This matters more than ever in 2026, since the Planning Inspectorate’s procedural guide and GOV.UK’s appeal guidance both now steer most cases toward a written procedure with little room for new evidence. Start by rereading your decision notice and talking to the local planning authority before you choose.

TL;DR:

  • Resubmitting a fixable refusal is faster and cheaper if the objection is about specific design or report issues that can be addressed with targeted changes.
  • Appeals are most effective when the original application already provided complete evidence; otherwise, resubmission is typically safer for fundamental policy disagreements.
  • From April 2026 onward, most appeals follow a written procedure that only considers evidence already in the original application, making thorough initial submissions critical.
  • The most common appeal route now is written representations, which are faster and lock in existing evidence; hearings and inquiries are used only for contested or complex cases.
  • Costs for appeals are higher and less predictable than resubmission, which typically involves a new application fee and targeted reports, making resubmission preferable for minor, specific fixes.

When resubmission is the right route for a fixable refusal

A refusal is “fixable” when the council’s objection is about something you can change or add, not about a fundamental clash with policy. Common fixable issues include a missing drainage or ecology report, an extension that is slightly too tall or deep for the street scene, or a design detail the case officer felt was out of character.

Resubmission rules allow a new application to be treated as exempt from the usual fee where it is by the same applicant, on the same site, for development of a similar character or description, and submitted within the time limits set out in the Development Management Procedure Order. Check your council’s validation list, since requirements vary by area.

Before resubmitting:

  • Commission the specific technical report the refusal cited, rather than resubmitting unchanged.
  • Book a pre-application meeting with the case officer to confirm your revised design addresses their concerns.
  • Make targeted design changes rather than a full redesign, so the application reads as a direct response to the refusal.
  1. Identify every refusal reason individually.
  2. Match each reason to a concrete fix.
  3. Confirm the fix with the planning officer before you submit.

Councils can still decline or return a resubmission that does not meet the exemption criteria, so early engagement with the local planning authority saves time either way.

When an appeal is appropriate under the new April 2026 Part 1 rule

An appeal suits cases where the disagreement is fundamental: the council and you read the same policy differently, or the planning balance (harm against benefit) was weighed differently than you expected. This is distinct from a factual gap, which a resubmission can close far more cheaply.

For applications dated on or after 1 April 2026, most section 78 appeals follow the Part 1 written representations procedure, under which inspectors will usually only consider the evidence the local planning authority already had, according to the Planning Inspectorate’s procedural guide. New technical reports introduced at appeal stage are normally not accepted.

The practical effect: an appeal only works well when your original application already contained a complete evidence base. If the council refused partly because something was missing, resubmission is the safer route.

Example: a single-storey rear extension refused for overlooking, with a full daylight and sunlight report already submitted, is a reasonable appeal candidate. The same refusal with no report on file is a resubmission candidate.

Decision path comparing appeal and resubmission

How appeals work: procedures, deadlines and typical timescales

Three procedures exist for planning appeals in England: written representations, hearings and public inquiries. Written representations is now the default for most householder and minor applications under the Part 1 reforms; hearings and inquiries are reserved for cases with significant public interest or complex evidence.

  • Written representations: paper-based, fastest, and the usual route from April 2026 onward.
  • Hearings: a round-table discussion with the inspector, used for moderately contested cases.
  • Inquiries: formal, cross-examination-based, used for major or highly contested schemes.

Standard appeals must usually be lodged within six months of the decision notice date, with shorter windows for some minor commercial cases, as set out in GOV.UK’s appeal form guidance.

The majority of appeals are now decided this way: Planning Inspectorate statistics show most decisions are made through written representations, with national allowed rates for section 78 appeals recently sit at about one-third, varying by procedure and council. Choosing written representations locks in whatever evidence the council already saw, since there is little scope to add more once the appeal is lodged.

Costs, risks and the financial trade-offs to weigh up

Appeals carry costs even without legal representation: there may be fees for additional reports needed to support your statement of case, and hearings or inquiries can involve paying a planning consultant or agent to represent you. Losing an appeal means those costs are sunk, plus the months spent waiting for a decision.

Resubmission costs are usually smaller and more predictable: a new application fee (unless the exemption under regulation 8 applies), plus the cost of any targeted survey or report the council asked for.

  • Appeal costs: statement of case preparation, any hearing or inquiry representation, risk of costs awards in rare cases.
  • Resubmission costs: possible application fee, targeted technical reports, revised drawings.
  • Redesign costs: architect or designer time to adjust plans in response to the refusal.

As a rough heuristic, if the fix is cheap and specific, resubmission usually wins on expected value. If the dispute is about policy and your evidence is already strong, an appeal can be worth the wait.

Pro Tip: When in doubt, get an appeal review from a qualified planning consultant before you commit either fee or time.

A concise decision checklist to apply now

  1. Read your decision notice line by line and sort each reason into “fixable” or “fundamental”.
  2. Check whether your original application already contains the technical evidence an inspector would need.
  3. Estimate the time and cost of both routes against your project’s deadline.
  4. Contact the local planning authority for an early conversation, and consider formal pre-application advice.
  5. If design or technical fixes address every reason, prepare a targeted resubmission.
  6. If the dispute is genuinely about planning judgement and your evidence file is already complete, consider an appeal.

Councils vary in how quickly they respond to pre-application queries, so build that into your timeline rather than assuming an instant answer. A short conversation with the case officer often reveals which category your refusal falls into before you spend money on either route.

Author perspective: how we advise homeowners facing a refusal

Most refusals we see on single-storey rear extensions come down to fixable issues: a missing report, a design detail, a measurement that overshot permitted limits slightly. A straightforward resubmission usually resolves these faster than an appeal would. Every case has its own detail, so treat this as general guidance rather than a substitute for reading your own decision notice carefully. For more on avoiding refusal in the first place, see our prior approval guide and design advice.

FAQ

How likely is a planning appeal to succeed?

Recent Planning Inspectorate statistics show the national allowed rate for section 78 appeals has recently been around 30%, though this varies by procedure and council. Success depends heavily on whether your original application already held the evidence an inspector needs.

What changed for planning appeals from 1 April 2026?

For applications dated on or after 1 April 2026, most section 78 appeals now follow the Part 1 written representations procedure, under which inspectors generally will not consider new evidence that the council had not already seen, according to the Planning Inspectorate’s procedural guide. This makes a complete original application more important than ever.

What are the different types of planning appeals?

The three main procedures are written representations, hearings and public inquiries, with written representations now the default route for most householder cases. Hearings and inquiries are reserved for more complex or contested schemes.

Can a planning appeal decision be overturned?

A planning appeal decision can be challenged in the High Court, but only on a point of law, not simply because you disagree with the outcome. This is a specialist legal process separate from the planning appeal itself, so professional legal advice is the right starting point.
