Economic evidence for a cluster of holiday lets

Holiday let economic evidence has one job: showing that the proposal is tourism and farm business, not housing by another route. A council reading an application for four or five units in a farmyard will test whether the jobs and spending are real, whether the units will actually be let rather than occupied permanently, and whether the holding needs the income. Get those three right and the landscape and highway points become manageable. Get them wrong and no amount of design quality rescues the application.

National policy supports sustainable rural tourism that respects the character of the countryside, and supports diversification of agricultural businesses. The work is in evidencing that your scheme is both.

What the economic case has to establish

Four propositions, in this order.

That there is demand for the type of accommodation proposed in this location. That the operation will generate employment and local spending of a stated scale. That the income supports the agricultural holding rather than replacing it. And that the use will remain holiday accommodation, enforceable by condition.

An Economic Impact Assessment is the usual home for the first two, and councils expect a suitably qualified author where the figures are doing heavy lifting on a contested site. Professional review of any draft before submission is sensible, because the numbers are the part a consultee will test.

Keep the document proportionate. A cluster of five units does not need the economic evidence base of a hotel, and a 60 page report on a small conversion signals that the applicant is worried.

Employment and visitor spend evidence

Two figures carry most of the weight, and both need a stated method.

Employment should be expressed as full time equivalent posts, split between construction and operation, and between direct and indirect. Direct operational employment on a small cluster is usually part time: changeover cleaning, laundry, grounds maintenance, booking administration. Say how many hours per unit per week, multiplied by the number of units, divided by a full time week. That arithmetic is transparent and defensible. Claiming three new jobs with no working is not.

Visitor spending needs a spend per visitor night figure and an occupancy assumption. Take the spend figure from a published source and cite it with its year, rather than estimating. Official statistics on tourism activity and spending are published nationally and regionally, and a figure with a source attached survives scrutiny that a round number does not.

Then show the proportion likely to be spent locally. A honest assessment says that a share of visitor spend leaves the area, names the categories likely to be spent within the village or market town, such as pubs, farm shops, attractions and fuel, and avoids claiming the whole sum as local benefit.

Seasonality and occupancy assumptions

Seasonality is where rural tourism applications are weakest and where officers are most sceptical.

State the assumed occupancy by month, not as an annual average. A scheme that assumes 85 per cent occupancy in August and 25 per cent in February tells the reader something useful. A scheme that assumes 60 per cent year round tells them the author has not looked.

Then sensitivity test. Run the employment and spend figures at your central case and at a lower occupancy, and say what happens to the business if the low case occurs. An assessment that survives its own pessimistic case is far more persuasive than one that only works at the optimistic end.

Showing the holiday use supports the holding

For a diversification argument, the farm business is part of the evidence.

What helps: the holding's area and enterprises, a short account of why the existing enterprises alone are marginal, the buildings proposed for conversion and why they are redundant for agriculture, and confirmation that the diversification does not compromise the agricultural operation. Where accounts are supplied, a summary form is usually enough, and most authorities will accept a statement from the farm's accountant rather than full accounts on the public register.

Redundancy of the building matters on a conversion. Say what the building was used for, when that use ceased or reduced, and why a modern agricultural operation cannot use it. A general statement that the barn is no longer needed invites the response that it could be used for storage.

Illustrative example. A 140 hectare mixed holding converts three redundant stone outbuildings into two-bedroom units, retaining a fourth for machinery. Changeover cleaning and laundry at six hours per unit per week across three units, at a 30 hour full time week, gives roughly 0.6 full time equivalent posts, before grounds maintenance and administration. Those figures are illustrative, and your own should come from the operator's actual intentions.

Occupancy conditions and the second home question

Councils grant these permissions on the basis that the units stay in holiday use, and they condition accordingly. Expect some combination of the following:

1. Occupation limited to holiday use only, with no person occupying any unit as a sole or main residence.
2. A maximum period of continuous occupation by the same party, commonly 28 days, with a minimum interval before return.
3. A register of occupiers to be kept, recording names, addresses and dates of occupation, and made available to the local planning authority on request.
4. The units to remain ancillary to the holding, or not to be sold off separately from it.
5. Restrictions on external lighting, parking layout and the siting of hot tubs or plant.

Read condition four carefully if you may wish to sell units individually in future. A tie to the holding affects value and mortgageability, and removing it later means a section 73 application with a fresh policy assessment.

On use classes, the position for self-catering holiday accommodation is not neatly resolved by the Use Classes Order, and authorities commonly deal with it by condition rather than by class. A new class for short-term lets has been proposed, so check the current position before relying on any class-based argument.

Highways, landscape and the counterweights

The economic case is a benefit in the balance, and the harms sit on the other side.

Highways usually comes first. A single track access with limited visibility and no passing places attracts an objection whatever the economic benefit, and the fix is measurable: visibility splays to the standard the highway authority applies, a passing bay, a bin collection point at the public highway. A short Transport Statement dealing with trip generation and parking is normally proportionate, and the arithmetic for peak parking demand across a cluster is set out in our note on occupancy accumulation in a parking survey.

Landscape matters where the site is in or near a National Landscape or a valued local landscape. A Landscape and Visual Impact Assessment addresses effects on character and on views, and it is the document that shows whether the scheme respects the character of the countryside as policy requires.

Drainage is the one that delays decisions. Rural sites rarely have mains foul drainage, so a package treatment plant or septic tank arrangement needs its own evidence, including percolation testing. The Foul Sewage Assessment covers it, and the sizing work has to be done before the layout is fixed because the drainage field takes space.

Where the evidence comes from

Build the file from sources you can name. Official tourism statistics for spend and occupancy. The authority's own economic development strategy or local plan evidence base, which often states a tourism priority you can cite back. The holding's accounts or an accountant's statement. Local operator experience, described rather than quantified where you cannot evidence it. The highway authority's standards for access geometry.

What not to do is obvious and still common. No invented occupancy figures, no claimed job numbers without arithmetic, no assertions about what visitors spend without a source, and no comparison to a named competitor's business.

Settle the drainage and access before the economic report is written, because both can change the number of units the site can carry. Enter your postcode on PlanScope to see which reports a rural diversification scheme is likely to need.
