Which reports holiday lodges on a farm need
Holiday lodge applications on farms turn on landscape effects, foul drainage and access rather than on the business plan. Here is the evidence each of those requires.
The reports needed for holiday lodges on a farm are driven by three things the council cannot check from a desk: how the units will look in open countryside, where the foul drainage will go, and how vehicles will reach the site. Those produce the landscape evidence, the drainage evidence and the access evidence, and they carry more weight than the business case. Add ecology and lighting, because lodges bring both new habitat impact and new light into a dark rural area. The business plan matters, and it matters as support for the occupancy conditions rather than as the main argument.
The policy support to build the case on
National policy supports sustainable rural tourism and leisure development that respects the character of the countryside, and supports the diversification of agricultural and other land based rural businesses. That is the hook, and it is a qualified one. Respecting the character of the countryside is the part your evidence has to satisfy.
Local plans usually add a sequence. Use existing buildings first where they are suitable, then sites well related to an existing group of buildings, then, least favourably, isolated locations. A proposal that puts lodges in the corner of a field 400 metres from the farmstead has to explain why the yard could not take them.
Cite the National Planning Policy Framework by its current edition, which was re-issued on 17 August 2026 with policy coded chapters, and take the code from the published text rather than copying a paragraph number from an older report.
Two further policy points come up often. Where the site is on best and most versatile agricultural land, the loss of that land is a consideration and permanent structures weigh more heavily than pitches. And if the site is in a National Landscape or National Park, the designated landscape policies apply and the bar rises considerably.
Landscape and visual effects
This is where applications for lodges are won and lost. Lodges are pale, horizontal, repetitive objects with roofs that catch the light, and they read as development in a way that a caravan on a field for a season does not.
The proportionate evidence depends on prominence. For a small number of units in a well contained site, a landscape strategy with a planting plan and a siting rationale is usually enough. Where the site is visible from higher ground, a promoted footpath or a designated landscape, a landscape and visual impact assessment prepared to the third edition of the Landscape Institute and IEMA guidance is the right document.
Five design decisions do most of the work.
- Site the units below the skyline, using existing landform rather than relying on new bunds.
- Use dark recessive colours and non reflective roof finishes, specified in the application rather than left to a condition.
- Break the units into groups rather than a row, and vary the orientation.
- Show the decking, hot tubs, storage sheds, bin stores and washing lines, because these appear on site whether or not they appear on the drawings.
- Plant with native species at a size that will do something within five years, and commit to replacement.
Include a winter viewpoint. A summer photograph through a hedge convinces nobody who has visited a rural site in February.
Foul drainage and water supply
Mains foul drainage is rarely available, so the application has to solve this properly. A foul sewage assessment should set out the number of units, the population equivalent, the treatment proposed, the discharge point and the evidence that the ground can take it.
The regulatory position matters. A small sewage discharge to ground through a drainage field can operate under the Environment Agency's general binding rules where it is within the stated daily volume, currently 2 cubic metres per day to ground and 5 cubic metres per day to surface water, and where the other conditions are met. Above those volumes, or where the rules cannot be satisfied, an environmental permit is required. Percolation testing to the relevant British Standard, with results and locations, is what turns an assertion into evidence.
Two traps. A drainage field needs space and separation from watercourses, boreholes and buildings, and on a small site the required area often conflicts with the lodge layout. And a package treatment plant discharging to a ditch is a surface water discharge, which changes the regulatory route.
Water supply needs the same treatment. Where the supply is a borehole or spring rather than mains, a water supply assessment covering yield, quality and the private supply regulations belongs in the pack.
Access, parking and internal tracks
The highway authority will look at the junction first. Visibility splays measured and drawn to the adopted standard, the width of the access, whether two cars can pass, and whether the lane serving the site has passing places.
Then the internal arrangement. One parking space per unit is the usual starting point, plus turning for a service vehicle and for the refuse collection if it comes onto the site. Track construction is a landscape issue as much as an engineering one, because a wide pale gravel track across a field is visible for miles.
Where the site is in a flood zone, the vulnerability classification matters. Holiday caravan and camping sites are generally treated as more vulnerable development, subject to a flood warning and evacuation plan, while caravans intended for permanent residential occupation are highly vulnerable. That distinction changes which flood risk tests apply, so state the intended use precisely.
Ecology, lighting and biodiversity gain
A preliminary ecological appraisal is the starting document, and on a farm site it commonly identifies bats using buildings or hedgerow lines, nesting birds, badgers, and ponds that may support great crested newts. Survey seasons then govern the programme, and the newt and bat windows are the ones that move a scheme into the following year if missed.
Lighting deserves specific attention because it is often the strongest objection from neighbours and from the ecologist. A lighting assessment following the Institution of Lighting Professionals guidance should identify the environmental zone, which for open countryside is at the dark end of the scale, and should show spill at the site boundary and along any hedgerow used by bats. Low level bollard lighting on a timer, with dark corridors retained, is the design that usually gets through.
Biodiversity net gain applies, and a lodge site on improved grassland is often straightforward to resolve through hedgerow planting and a species rich margin. That only works if the baseline survey happened before the layout was fixed. Where the site sits within an impact risk zone for a designated site, the article on reports needed inside an SSSI impact risk zone sets out the consultation that follows.
Occupancy conditions and the site licence
Councils grant holiday accommodation permissions subject to conditions that keep the use as holiday accommodation, because a permanent dwelling in the countryside would not be permitted on the same site.
The conditions commonly used restrict occupation to holiday purposes only, prohibit use as a sole or main residence, set a maximum continuous period of occupation by any one party, and require a register of occupiers to be kept and made available to the authority on request. Read the wording carefully before you accept it, because a condition that suits a family letting business can be unworkable for one selling long season pitches.
Planning permission is not the only consent. A caravan site, including one with twin unit lodges falling within the statutory definition of a caravan, needs a site licence from the council under the caravan site legislation, and the licence conditions cover spacing, roads, fire points and facilities. Apply for both and check that the layout satisfies the licensing spacing standards before the planning drawings are finalised.
Business evidence that supports the case
An illustrative example: four lodges on a 90 hectare mixed farm, sited in a former silage clamp behind an existing shelterbelt. The application included a landscape strategy with a winter viewpoint, percolation tests at two locations with a drainage field shown clear of the watercourse buffer, a preliminary ecological appraisal with bat activity survey of the adjoining hedgerow, and a short business statement setting out the seasonal pattern of the farm income and the role of the lodges within it. The occupancy condition was agreed in draft with the officer before determination.
Keep the business material factual. Describe the existing enterprise, the reason for diversifying, the intended letting pattern and how the lodges relate to the farm business. Do not present projected visitor numbers or revenue as though they were evidence, because they are not, and an officer will treat unsupported figures accordingly.
This is general guidance rather than legal advice. Check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
Do holiday lodges need a site licence as well as planning permission?
Usually yes. Where the units fall within the statutory definition of a caravan, including twin unit lodges, the site needs a licence from the council under the caravan site legislation. Licence conditions cover spacing between units, roads, fire points and facilities, so check the layout against the licensing standards before the planning drawings are finalised.
What drainage evidence does the council expect?
The number of units and population equivalent, the treatment proposed, the discharge point, and percolation test results with locations. A small discharge to ground through a drainage field can operate under the Environment Agency general binding rules within the daily volume limits, currently 2 cubic metres to ground and 5 to surface water. Above those an environmental permit is required.
Are holiday caravans treated the same as residential caravans in a flood zone?
No. Holiday caravan and camping sites are generally treated as more vulnerable development, subject to a flood warning and evacuation plan, while caravans intended for permanent residential occupation are highly vulnerable. The distinction changes which flood risk tests apply, so state the intended use precisely in the application.
What occupancy conditions should I expect?
Conditions restricting occupation to holiday purposes, prohibiting use as a sole or main residence, setting a maximum continuous period of occupation by any one party, and requiring a register of occupiers to be kept and produced on request. Read the wording before accepting it, since a condition suited to family lettings may not suit long season pitches.
Does biodiversity net gain apply to a lodge site?
Yes, the gain condition applies to the permission in the normal way. On improved grassland the uplift is often achievable through hedgerow planting and a species rich margin, which works only if the baseline habitat survey was done before the layout was fixed. The gain plan must be approved before development starts.
