Holiday lets in rural buildings: which use class applies

There is no holiday let use class. The Town and Country Planning (Use Classes) Order 1987 has no category for self-catering holiday accommodation, so the use class of a rural holiday let depends on what the building was lawfully used for before and on how the letting actually works in practice. Most commercially let barns and cottages end up treated as sui generis. Some sit in Class C1. A few remain Class C3. Which of those applies decides whether you need planning permission at all, and it decides what the council can control by condition afterwards.

Whether a holiday let is C1, C3 or sui generis

Class C3 covers use as a dwellinghouse by a single person or household, or by up to six people living together as a single household. Class C1 covers "use as a hotel or as a boarding or guest house where, in each case, no significant element of care is provided". A self-catering cottage with no reception, no staff on site and no meals does not sit comfortably in either. That is why councils and inspectors so often land on sui generis, which means the use falls outside every class and any change to or from it needs express permission.

The consequence matters more than the label. If the holiday use is sui generis, moving a former farm cottage into it is a material change of use and needs permission. If a court or inspector accepts that occasional letting of a family holiday home is still residential use, there is no development at all.

In Moore v Secretary of State for Communities and Local Government [2012] EWCA Civ 1202 the Court of Appeal accepted that intensive commercial letting of a large house to successive groups could amount to a material change of use away from residential occupation. The judgment turns on fact and degree rather than on a bright line, which is why two apparently similar barns in the same parish can get different answers.

Turnover, services and the question of fact and degree

Officers look at how the property is used across a year, not at the marketing copy. The factors that shift the answer are practical ones.

• How many separate lettings there are in a year, and how long each stay lasts
• Whether the owner or a manager lives on site and attends between lets
• Whether meals, cleaning during the stay, linen changes or activities are provided
• Whether the unit has its own entrance, parking and curtilage or shares the host dwelling's
• How the property is described and priced when it is advertised

A four-bedroom cottage let for 32 weeks of the year to a succession of one-week parties, cleaned and changed over every Friday, is a commercial operation. The same cottage let for six weeks in the summer while the family uses it the rest of the year is much closer to residential use. And a converted barn let alongside breakfast served in the farmhouse starts to look like Class C1.

Self-catering units in converted buildings

Class Q of Schedule 2 Part 3 to the General Permitted Development Order 2015 permits the conversion of an agricultural building to a dwellinghouse, and the dwellinghouse it delivers is Class C3. Letting that unit commercially afterwards is a further change of use, which Class Q does not authorise. Owners regularly discover this at the point the council refuses to certify the holiday use as lawful. If you intend holiday letting from the outset, say so and apply for it, rather than taking the Class Q prior approval route to a dwellinghouse and hoping the difference goes unnoticed.

Class R in the same Part permits change from an agricultural building to a flexible commercial use, and the list of uses it allows includes Class C1. That makes it a real route for a guest house or bed and breakfast operation in a redundant building, though it carries a floorspace cap and a prior approval procedure. The cap has been amended, so read the current text of the Order rather than an older summary.

Where the building has already been converted to something else, or where two uses run side by side on the same holding, the description on the form has to carry that complexity. Getting a mixed use described correctly on the application form saves an argument about the extent of the permission years later.

Occupancy conditions and what they commit you to

Expect a holiday occupancy condition. The usual form restricts occupation to holiday purposes only, prevents any single period of occupation beyond a stated number of weeks, prohibits use as a sole or main residence, and requires a register of lettings to be kept and produced to the council on request.

That condition is the price of permission in the countryside, because a permanent dwelling in the same location would fail the policy tests on isolated homes. It also has consequences the planning system does not mention. Lenders treat holiday-condition units differently from unrestricted dwellings, and the restriction follows the land.

Conditions still have to meet the six tests in the Planning Practice Guidance on the use of planning conditions: necessary, relevant to planning, relevant to the development permitted, enforceable, precise and reasonable in all other respects. A condition requiring a register is enforceable. A condition limiting occupation to people resident more than 50 miles away is not. If a condition becomes unworkable, section 73 of the Town and Country Planning Act 1990 is the route to vary it, and the council will reconsider the countryside policy position when it does.

Access, parking and drainage evidence on a rural site

Highway objections sink more farm diversification schemes than landscape objections do. A single-track lane with no passing places and poor visibility at the junction is a real constraint, and the highway authority will ask what the change in vehicle movements looks like against the existing agricultural use. Two holiday units generate steadier, more predictable trips than a working yard, which sometimes helps. A short Transport Statement covering visibility splays, turning and on-site parking for each unit usually answers it.

Foul drainage needs an answer before validation, not after. If there is no public sewer within reach, a package treatment plant or septic tank discharging to a drainage field will need to satisfy the general binding rules for small sewage discharges, and a new discharge to a watercourse needs a permit from the Environment Agency. Private water supplies bring the council's environmental health team into the picture under the Private Water Supplies (England) Regulations 2016, and a supply serving paying guests is treated as a commercial supply with sampling duties attached.

Illustrative example: a stone barn of about 90 m² on a working farm, 400 m along a private track off an unclassified lane. The application describes change of use to two units of self-catering holiday accommodation, with four parking spaces inside the existing yard, a new package treatment plant to the west of the barn, and the farmhouse retained as the host dwelling. Figures here are illustrative only.

Business rates and council tax

Business rates and planning are separate systems, and neither one settles the other. In England a self-catering property is assessed for business rates instead of council tax where it was available for commercial short-term letting for at least 140 days in the previous and current year and was actually let for at least 70 days in the previous 12 months. The thresholds are published by government and are worth checking before you assume a rating change follows.

A rating list entry is sometimes used as evidence by an enforcement officer, because it shows the property being marketed commercially. It does not make an unauthorised use lawful. Only a lawful development certificate under section 191 or 192 of the 1990 Act confirms that.

Describing the use so future flexibility survives

Write the description of development narrowly enough to be accurate and widely enough to be useful. "Change of use of agricultural building to two units of self-catering holiday accommodation, with associated parking and package treatment plant" tells the council exactly what it is granting. "Conversion of barn to holiday cottages" invites an argument about whether cottages are dwellings.

Set out the fallback position too. If the barn already benefits from a Class Q prior approval, or if it could be used for storage under Class R, say so in the Planning Statement and explain why the holiday use is the better outcome for the building and the landscape. Government has consulted on changes to the treatment of short-term lets in England, including a separate use class and a registration scheme, so check the current position on gov.uk before you rely on the classification above.
