Answering a refusal based on loss of employment land

A refusal citing loss of employment land is a refusal about evidence, and the evidence the authority wants is nearly always marketing and viability. Local plan policies protecting employment sites are drafted with exceptions, and almost all of them turn on whether the site has a reasonable prospect of continued employment use. Answering the refusal means proving it does not, in the way the policy asks and with documents a planning officer or an inspector can test. Rearguing the principle of redevelopment rarely works.

The national position helps. The current Framework, published on 17 August 2026, retains the long-standing expectation that policies should avoid the long-term protection of sites allocated for employment use where there is no reasonable prospect of a site being used for that purpose. Check the policy code in the current edition before citing it, because the Framework moved to policy-coded chapters in that edition.

How employment protection policies are drafted

Read the policy word by word before you write anything. Three drafting patterns recur and each demands a different answer.

The first protects allocated employment land and permits loss only where the site is demonstrably unsuitable or unviable for employment use. The second protects employment floorspace wherever it occurs, allocated or not, and often applies a floorspace threshold. The third protects a defined employment area as a whole, so the question becomes the effect on the area rather than on your site.

Identify which pattern you are dealing with, then identify the exception route the policy itself provides. A refusal is usually a finding that you did not satisfy the exception, not a finding that the exception does not exist. Reading the reasons for refusal carefully before you decide how to respond is the step that saves the most wasted work here.

What counts as marketing evidence

Councils ask for marketing evidence because it is the most direct test of demand. What they accept is narrower than what applicants usually supply.

A credible marketing exercise has these features:

• A commercial agent with local industrial or office experience, formally instructed, with the instruction letter available.
• A board on site, visible from the public highway, for the whole period.
• Particulars circulated to the agent's applicant list and placed on the main commercial listing channels.
• Advertising at a realistic rent or price, evidenced by comparable transactions rather than by aspiration.
• A written record of every enquiry, who made it, what they wanted, and why it did not proceed.
• Evidence of price or rent reductions during the period, with dates.

The enquiry log is the item that persuades. A schedule showing fourteen enquiries over eighteen months, of which nine wanted a smaller unit, three wanted a different location and two withdrew after inspecting the building's condition, is a far stronger case than a bare statement that the property did not sell.

The most common failure is marketing at a price set by the residual value of the alternative use. If the asking rent is above the range shown by comparable lettings in the area, the council will say the site was never really offered, and it will usually be right.

Length and method of the exercise

Policies vary on duration, and many local plans or supplementary documents specify a minimum period. Where the policy states one, meet it. Where it does not, twelve months is generally treated as the floor and longer is safer on a larger or more unusual building.

Continuity matters as much as length. Marketing that stopped for four months while an agent changed does not read as a continuous exercise, and an inspector will discount the gap. So will a period that ran wholly through a market disruption, which cuts both ways and is worth addressing openly rather than hoping nobody notices.

One practical point. If you are at the start of this process and considering a residential scheme on an employment site, begin the marketing before you submit, not after the refusal. Marketing started after a refusal is admissible, but it delays everything by the length of the exercise.

Viability of continued employment use

Marketing shows there is no occupier at the price offered. Viability shows why there could not be one at any price that supports the building.

The appraisal needs to be specific to the building. Refurbishment or reconfiguration cost, priced by a cost consultant from a condition survey rather than estimated per square metre. Achievable rent from comparable lettings. Yield evidence for that asset class in that location. Void and letting assumptions. The resulting value compared against the cost of putting the building into a lettable state.

Where the numbers show that refurbishment cost exceeds the value it creates, you have the substantive answer to the policy, and a Viability Assessment prepared by a qualified valuer is the document that carries it. Where they do not, the honest conclusion is that this policy argument will fail and a different route is needed.

Using the authority's own evidence base

The authority's employment land review or economic needs assessment is public, and it is frequently the best evidence available to an applicant.

Look for four things in it. Whether your site is identified as a quality employment site or as one of poorer quality. Whether the study concludes there is a surplus or a shortfall of employment land in the district. Whether it recommends releasing any sites. And how old the study is relative to the plan and to current market conditions.

A conclusion in the council's own study that the borough has a surplus of lower-quality industrial land, coupled with your site being categorised in that lower tier, is a powerful and difficult-to-contradict point. An Employment Land Assessment for your application should engage directly with that document rather than presenting a parallel analysis, because the officer will read them side by side. If the loss of jobs is being weighed against gains from the proposed use, an Economic Impact Assessment puts both sides of that balance in one place.

Alternatives the policy already allows

Before building an appeal case, check whether the policy offers an easier route.

Many policies permit loss where replacement employment floorspace is provided on site, which makes a mixed use scheme viable where a wholly residential one is not. Some permit change to another employment-generating use within a broader definition, so a switch from industrial to a workspace or light industrial hybrid may be compliant on its face. Some allow loss of part of a site where the remainder is intensified. And where the building is obsolete, a policy hook based on unsuitability may be easier to prove than one based on unviability, since condition is observable and demand is contested.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.

Putting the case at appeal

Build the appeal around three documents and make them agree with each other.

1. A marketing report from the instructed agent, in their name, with the enquiry log and the instruction letter appended.
2. A viability appraisal from a qualified valuer, with the cost plan attached and the assumptions listed.
3. A planning statement that ties both to the words of the policy and to the current Framework, addressing the exception route explicitly.

Then agree what you can with the council before the statements are exchanged. Marketing dates, the asking price, the number of enquiries and the building's floor area are all facts, and agreeing them narrows the appeal to the judgement. Refusals founded on the loss of an employment site turn on that judgement more often than on the figures, so the less that is in dispute about the figures the better.
