Retail loss policies and the marketing evidence test

Development plan policies protecting shops do not stop a change of use. They set an evidential hurdle, and the hurdle is almost always marketing. A typical loss of retail unit policy evidence requirement asks for continuous marketing of the unit for a stated period, at a realistic rent or price, through a commercial agent, with the enquiries and outcomes recorded. Fail the evidence and the application is refused on policy grounds without anyone reaching a view on the merits of the new use.

The first question, though, is whether the policy applies to your change at all. Since the 2020 revision of the Use Classes Order, it often does not.

Where Class E has already removed the issue

Class E covers shops, financial and professional services, cafés and restaurants, indoor sport, medical and health services, creches, offices, research and development, and light industry. Movement between those sub-classes is not development, so no permission is needed and no policy test applies.

That matters enormously for retail frontage policies written before 2020. A shop becoming a café, a dental practice, a gym or an office is now outside the planning system entirely, unless an Article 4 direction has removed the relevant right in that area.

So the policies now bite in a narrower set of cases.

• A change out of Class E to residential use in Class C3, whether by full application or under the prior approval route in Part 3 Class MA.
• A change to a sui generis use such as a hot food takeaway, a drinking establishment, a betting office or a payday loan shop.
• A change to Class F1 or F2, for example a place of worship or a community hall.
• Any change in an area where an Article 4 direction has withdrawn Part 3 rights or constrained movement.
• Demolition and redevelopment, where the loss of floorspace is assessed as part of the scheme.

Check the Article 4 position first. Many authorities made directions covering their centres after 2021 precisely to keep control of the residential conversion route, and the direction will define the area and the right withdrawn.

Primary and secondary frontages

Where a policy does apply, the designation of the unit usually determines how hard the test is. Plans commonly distinguish a primary shopping frontage, where retail is protected most strongly, from a secondary frontage where a wider range of uses is accepted, and then from the wider centre boundary where policy may be permissive.

Read the designation off the policies map rather than from the address. Frontages are drawn unit by unit, and the boundary frequently runs through the middle of a parade. A unit two doors outside the primary frontage faces a materially easier test than its neighbour.

Then read the policy wording itself for the criteria it actually sets. The common ones are the effect on the vitality and viability of the centre, the retention of an active frontage at ground floor, the proportion of non-retail uses within a defined stretch, and the marketing requirement. Answer each in turn, in the order the policy sets them out.

The marketing period, and what counts

The duration is the part people get wrong. Policies usually require the marketing to be continuous and recent, so a twelve-month campaign that ended three years ago does not satisfy a requirement for current evidence. If the unit has been marketed on and off, present a timeline rather than a total.

Price is where most cases are actually lost. An officer who finds the asking rent above comparable lettings in the same parade will conclude the unit was not really available, and the rest of the evidence stops mattering. Deal with it directly: give the asking terms, give three or four comparable transactions with dates, and explain any difference.

What the marketing record should contain

Assemble this as an appendix with a short summary at the front.

1. The agent's instruction letter with the date and the terms of appointment.
2. Dated copies of the particulars as published, and screenshots of the listings with dates.
3. Photographs of the board on site, dated.
4. A schedule of every enquiry: date, enquirer type, use proposed, and the reason it did not proceed.
5. A schedule of viewings and offers, with the reason any offer was rejected.
6. The agent's written opinion on demand for the unit in its current configuration.
7. Comparable evidence supporting the asking terms.

Point four is what distinguishes a credible record. "No interest received" is an assertion. Fourteen enquiries of which nine wanted a use the landlord could not grant and five withdrew after seeing the condition of the unit is an argument.

Evidence about the unit and the centre

Marketing shows what the market did. The rest of the case explains why.

Describe the unit's physical constraints: frontage width, depth, floor-to-ceiling height, rear servicing, whether there is a separate access to upper floors, condition, and any listed building or structural constraint. Deep narrow units and units with no rear access are hard to let for retail, and saying so with dimensions is more persuasive than saying so in adjectives.

Then describe the centre. Vacancy along the frontage, counted and mapped on a stated date. The mix of uses in the stretch the policy refers to, with each unit's current use recorded. Footfall or pedestrian activity where you have observed it, described honestly as an observation rather than dressed up as a survey. Where the upper floors are in play, the position on whether upper floors are a separate planning unit affects both the marketing you should have done and the scheme you can apply for.

Do not assert anything about how the council has treated other applications unless you can cite the decision notice and reference. Officers check.

Presenting the case

Lead with the policy, not the proposal. Set out the policy text, then the criteria, then your evidence against each criterion with a cross-reference to the appendix. A Planning Statement structured that way is much harder to refuse on evidential grounds, because the officer report has to engage with each point.

Deal with the alternative uses the policy prefers. Most retail protection policies accept a hierarchy, so explain why the uses higher up that hierarchy were tested and did not work. If a meanwhile or interim occupier approached you, say so, and read the risks around temporary and meanwhile uses before offering a short let as part of the answer.

And acknowledge the honest uncertainty. The level of marketing evidence considered sufficient varies between authorities and is a planning judgement rather than a formula. Ask at pre-application stage what the officer expects, in writing, and start the clock on the marketing that day.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it. The Use Classes Order and Part 3 of the GPDO have both been amended more than once, including changes to Class MA, so read the current text before relying on a route.
