Refusal for failing the retail sequential test
A sequential test refusal means your site search did not prove no preferable site was available. How to rebuild the evidence and where the 2,500 m² threshold bites.
A retail sequential test refusal almost never means the council thought your shop was a bad idea. It means your site search did not demonstrate that no suitable sequentially preferable site was available, and the refusal reason will say so in those words. The test is a documentary exercise with a defined method, and most failures are failures of evidence rather than of principle.
Fix the evidence and the same proposal on the same site can succeed. That is the useful thing to know after a refusal.
What the sequential test actually asks
The current National Planning Policy Framework, published on 17 August 2026, carries the town centre first approach in its chapter on the vitality of town centres. The December 2024 edition stated the same tests under paragraph numbers, and the Framework now uses policy codes, so state the edition when you cite it.
The test applies to main town centre uses that are neither in an existing centre nor in accordance with an up to date development plan. Retail, leisure, offices, arts, culture and tourism development all fall within the definition of main town centre uses, so a gym, a soft play centre and a trampoline park are caught alongside a food store.
The sequence is: sites in the centre first, then edge of centre sites, then out of centre locations with a preference for accessible sites well connected to the centre. The applicant has to demonstrate that there are no suitable sequentially preferable sites available.
Two words carry the whole argument. Suitable, and available.
Defining the catchment and the search area
The search area has to be justified, and this is where refusals start.
Define it from the proposal's likely trade draw rather than from the council's administrative boundary. A convenience store draws from a walk in catchment measured in minutes. A trade counter draws from a drive time catchment covering several authorities. A gym draws from a radius that depends on membership pricing and competing provision.
Then identify every centre within that catchment, using the local plan's own centre hierarchy and the boundaries on the proposals map. Not your own view of where the high street is. The plan defines the primary shopping area and the centre boundary, and the sequential assessment has to work to those lines.
Where the catchment crosses into a neighbouring authority, include the centres on the other side. An assessment that stops at the district boundary invites the objection that the search was artificially narrow, and it is one of the easier points for an objector to make.
Date the search. A schedule compiled eighteen months before submission will be out of date, and sites will have changed hands.
Flexibility, suitability and availability
Flexibility is required of the applicant, on format, scale, the configuration of floorspace and car parking provision. A search that tested only sites capable of taking your exact standard layout with your exact parking ratio is not a sequential assessment, it is a site acquisition brief.
What flexibility does not require is accepting a scheme that would not work. The leading authority here is a Supreme Court decision from 2012 concerning a Scottish application, which established that suitable means suitable for the development proposed by the applicant rather than suitable for some different development the decision maker might prefer. That principle is what allows an applicant to resist being told to split the proposal across three small units.
Nor is disaggregation generally required. Planning Practice Guidance on town centres and retail is the place to go for how far flexibility extends, and it does not expect a single proposal to be broken up across multiple sites as a matter of course.
Availability is the other half, and it is interpreted more broadly than applicants like:
| Position | How it is usually treated |
|---|---|
| Site vacant and on the market | Available |
| Site in third party ownership, not marketed, no committed alternative use | Potentially available, and you must evidence why not |
| Site with an extant permission for another use, not implemented | Potentially available |
| Site occupied under a lease expiring within a reasonable period | Potentially available |
| Site in active use with no prospect of release | Not available, with evidence |
"The owner would not sell to us" is weak unless you have written evidence of the approach and the refusal. Make the approach, in writing, and keep the reply.
The impact assessment threshold
Separate test, often confused with the sequential one.
Where a proposal for retail, leisure or office development is outside a centre and not in accordance with an up to date plan, an impact assessment is required if the floorspace exceeds a locally set threshold, or 2,500 m² gross where the plan sets none. Check the local plan first, because many authorities set thresholds far lower, sometimes a few hundred square metres in sensitive centres.
The assessment considers the impact on existing, committed and planned investment in a centre within the catchment, and the impact on town centre vitality and viability, including local consumer choice and trade. The assessment period runs to five years from the application, or ten years for major schemes with a phased development.
Where a proposal fails the sequential test, or is likely to have a significant adverse impact on either limb, the Framework says it should be refused. Those are two independent grounds, and a refusal notice sometimes cites both when only one was actually made out. Read the reasons carefully before deciding what to fix.
A retail impact assessment is the document that addresses the second test, and a sequential test addresses the first. They are separate submissions with separate methods, and combining them into one chapter tends to muddle both.
Presenting the site search so it survives scrutiny
The format that works is a schedule, a set of plans and a short methodology note.
- A methodology paragraph stating the catchment, how it was derived, the centres identified, the date of the search and the sources used.
- A plan showing the search area, every centre boundary and primary shopping area taken from the proposals map, and the application site.
- A schedule listing every site considered, with its address, area in square metres, planning status, ownership, marketing status and availability.
- For each discounted site, the reason, under the headings of suitability or availability, with evidence attached.
- A statement of the flexibility applied, naming the specific parameters that were varied during the search.
- Copies of the written approaches made to landowners and their replies.
The fifth item is the one most often missing and the one inspectors most often criticise. Say what you were prepared to change, and show a site that was discounted for a reason other than it not matching the brief.
Where an edge of centre site changes the answer
Edge of centre is defined in the Framework glossary, and for retail it means a location well connected to and within easy walking distance of the primary shopping area, generally within 300 m of it.
That 300 m figure does real work. A site 250 m from the primary shopping area on a safe, direct pedestrian route is sequentially preferable to your out of centre site and has to be addressed. A site the same distance away across a dual carriageway with no crossing may not function as part of the centre at all, and that is an argument worth making with a walking route plan and photographs rather than a measured radius.
Connectivity is assessed as experienced, not as drawn. Gradients, severance, lighting, legibility and the quality of the route all come into it.
Common failings and the route after refusal
From the pattern of appeal decisions rather than any single case: search areas drawn too tightly, flexibility asserted but not evidenced, availability equated with being on the market, out of date schedules, and sites discounted because they did not suit the operator's commercial model rather than because they were unsuitable for the development proposed.
After a refusal you have three routes. Appeal under section 78 within six months, with a rebuilt sequential assessment and the evidence that was missing. Resubmit with a revised scheme that reduces floorspace below the local threshold, which removes the impact assessment requirement though not the sequential test. Or accept the finding and look at the sequentially preferable site.
Appeal decisions on comparable proposals are useful for framing the argument, and the piece on using appeal decisions in a planning application sets out how to deploy them without treating them as binding. Where the proposal brings employment or regeneration benefits, an economic impact assessment gives the decision maker something to weigh on the other side of the balance.

Frequently asked questions
What does the sequential test require?
That an applicant for main town centre uses outside a centre, and not in accordance with an up to date plan, demonstrates there are no suitable sequentially preferable sites available. The sequence runs from in centre, to edge of centre, to out of centre locations well connected to the centre.
Which uses are caught by the test?
Main town centre uses as defined in the Framework, which covers retail, leisure, offices, arts, culture and tourism development. A gym, a soft play centre and a trampoline park are caught alongside a food store, which surprises many occupiers taking space on an out of centre estate.
What does suitable mean in the sequential test?
Suitable for the development proposed by the applicant rather than for some different development the decision maker might prefer. A Supreme Court decision in 2012, on a Scottish application, settled that point. It is what allows an applicant to resist being directed to split a proposal across several small units.
When is a retail impact assessment required?
Where retail, leisure or office development outside a centre exceeds a locally set floorspace threshold, or 2,500 m² gross where the plan sets none. Check the local plan first, because many authorities set much lower thresholds, sometimes a few hundred square metres in sensitive centres.
Does a site have to be on the market to be available?
No. Sites in third party ownership, sites with unimplemented permissions for other uses and sites with leases expiring within a reasonable period are all treated as potentially available. Discounting one requires evidence, which means a written approach to the owner and their written reply.
What counts as edge of centre?
For retail, a location well connected to and within easy walking distance of the primary shopping area, generally within 300 m of it. Connectivity is judged as experienced rather than as measured, so severance by a dual carriageway with no crossing is a point worth evidencing with a route plan and photographs.
