Reports needed for a tennis court in a large garden
The court surface may fall within householder permitted development while the enclosure and lighting do not. Curtilage, trees, lighting and drainage decide these applications.
A tennis court in a back garden is often permitted development, and the fence around it and the lights above it usually are not. That is the practical answer, and it explains why so many of these projects start as a no-application job and end up at the council. The court surface itself can fall within the hard surface right for dwellinghouses. Enclosure above 2 metres and any floodlighting take you into a planning application, and once you are applying, the court comes with you.
Work out which category you are in before you commission anything. The documents a council expects for a court with 3 metre fencing and eight floodlights bear no resemblance to those for a plain all-weather surface behind a hedge.
What the proposal is in planning terms
Within the curtilage of a dwellinghouse, Class F of Part 1 of Schedule 2 to the General Permitted Development Order 2015 permits a hard surface for any purpose incidental to the enjoyment of the dwellinghouse. A tennis court for the household's own use fits that description. Where the surface sits between the principal elevation and the highway it must be porous or drain to a permeable area within the curtilage.
Three things commonly take a court outside the right.
The land is not curtilage. A paddock or field beyond the garden boundary, even in the same ownership, is not part of the residential curtilage, and a court there is development needing permission in the countryside. This is the single most frequent mistake.
Permitted development rights have been removed, by an Article 4 direction or by a condition on the original planning permission for the house. Estate-wide conditions from the 1970s and 1980s still bite.
The use is not incidental. A court let out commercially, or used by a coaching business, is not incidental to the enjoyment of the dwellinghouse.
If the court is permitted development but the fence and lighting are not, the application covers the fence and lighting, and the officer will assess the whole development in front of them. That is not a reason to leave the court out of the drawings.
The documents every application of this kind needs
- A location plan and a block plan at a recognised scale, showing the court position and distances to boundaries and neighbouring windows
- Existing and proposed levels, with cross-sections where the garden slopes
- Details of the enclosure: height, material, colour and post specification
- Lighting details if proposed: column heights, luminaire specification, aiming angles and hours of use
- A short planning statement dealing with amenity, drainage and any constraints
- A surface water drainage note
Levels are the item householders skip and officers ask for. A court needs a flat platform, and a sloping garden therefore needs cut and fill, retaining structures or both. A drawing showing existing and finished levels answers the question an officer will otherwise raise at week four.
The report index lists the supporting documents available if constraints push you beyond the basic set.
Constraint checks that add reports
| Constraint | What it adds |
|---|---|
| Trees on or near the court area, protected or not | Arboricultural impact assessment to BS 5837:2012 |
| Listed building, including curtilage structures | Heritage statement, and listed building consent for works to curtilage structures |
| Conservation area | Heritage statement addressing character and the loss of garden |
| Green Belt | Openness assessment, with floodlighting addressed directly |
| National Landscape or National Park | Landscape and visual appraisal, usually with a lighting position |
| Flood Zone 2 or 3 | Flood risk assessment, addressing displaced flood storage from any raised platform |
| Protected species potential in hedges, outbuildings or ponds | Ecological appraisal |
Biodiversity net gain does not apply to householder applications, which is worth knowing because contractors sometimes quote for a metric that is not required. Check the current exemptions before accepting advice either way.
Trees are the real constraint on most large gardens. Court construction involves excavation across the whole playing area, and that cuts roots within the root protection areas of nearby trees. A tree survey and impact assessment prepared to BS 5837:2012 will show whether the court can be positioned clear of the protection areas, and councils usually expect a suitably qualified author with professional review.
Curtilage coverage and the hard surface rules
Curtilage has no statutory definition and is a question of fact. Officers look at the physical enclosure of the land, how it has been used, and whether it serves the house.
Two tests help on the ground. Has the land been treated as garden, with lawn, planting and ornamental use, as opposed to grazing or agriculture. And is it enclosed with the house rather than separately. A strip taken into the garden three years ago, still with a post and wire fence and a field gate on the far side, is unlikely to persuade.
Where the answer is still uncertain, an application under section 192 of the Town and Country Planning Act 1990 for a certificate that the proposed court would be lawful is the only formal way to get certainty. It costs less than an enforcement dispute and far less than removing a finished court. This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
Floodlighting and neighbour amenity
Floodlighting is where applications are refused. Columns of 6 to 8 metres with floodlights aimed across a garden are visible from a long way off, and the assessment is against the Institution of Lighting Professionals guidance on obtrusive light using the environmental zone for the area.
What a persuasive lighting submission contains: the column positions and heights, luminaire types with full cut-off optics, aiming angles, calculated vertical illuminance at the nearest neighbouring windows, calculated upward light ratio, and proposed hours of use with an automatic cut-off.
A Lighting Assessment at this scale is modest work and it changes outcomes, because it replaces an argument about whether lights are intrusive with numbers against a published standard. Expect a condition limiting use to defined hours, commonly ending by mid-evening, and expect rural authorities in dark landscapes to resist lighting altogether.
In the Green Belt the national policy position treats facilities for outdoor sport and recreation as capable of being appropriate development where openness is preserved. Check the current wording in the August 2026 edition of the National Planning Policy Framework. Lighting columns and high mesh fencing are what usually defeat the openness argument, so if you are in Green Belt, consider an unlit court with a lower enclosure.
Drainage from a new impermeable surface
A full-size court plus run-off areas is a large new surface, and where it is impermeable the water has to go somewhere other than the neighbour's garden.
Three approaches work. A porous macadam or open-graded surface that infiltrates where the ground conditions allow. A permeable sub-base acting as attenuation, discharging slowly to a soakaway sized on an infiltration test. Or perimeter channel drainage to a soakaway at an appropriate distance from buildings and boundaries.
Do an infiltration test before choosing. Clay subsoil defeats soakaways, and discovering that after construction means a pumped or piped solution and a conversation with the water company. For larger or more complicated schemes a Drainage Strategy sets the calculation out formally.
Sequencing the commissions
- Confirm the curtilage boundary and check the title plan against what is on the ground
- Check the planning history for conditions removing permitted development rights, and check for an Article 4 direction
- Check designations: listed building, conservation area, Green Belt, National Landscape, flood zone, tree orders
- Survey levels and existing trees before fixing the court position
- Carry out an infiltration test
- Decide on lighting, because it determines whether this is a simple application or a contested one
- Prepare the drawings and the statement, and submit against the council's validation list
Where a court has already been built and the position is uncertain, the route is a retrospective application, and the evidence it needs is set out in documents for a retrospective application.

Frequently asked questions
Do I need planning permission for a tennis court in my garden?
The surface itself can be permitted development under Class F of Part 1 of Schedule 2 to the General Permitted Development Order 2015, as a hard surface incidental to the enjoyment of the dwellinghouse within the curtilage. Fencing above 2 metres and any floodlighting need permission, and once you apply the court is assessed with them.
Is a paddock next to my garden part of the curtilage?
Usually not. Curtilage is a question of fact turning on physical enclosure and how the land has been used. A field in the same ownership, enclosed separately and not treated as garden, is unlikely to count. A certificate under section 192 of the Town and Country Planning Act 1990 is the only way to get certainty.
How high can the court fencing be without permission?
Fences, walls and gates up to 2 metres are generally permitted development, reduced to 1 metre where adjacent to a highway used by vehicular traffic. Tennis court enclosure is normally higher than that, so it needs planning permission along with any lighting columns.
Will the council allow floodlights?
It depends on the location and the evidence. Submit column positions and heights, luminaire specifications with full cut-off optics, aiming angles, vertical illuminance at the nearest neighbouring windows, upward light ratio and proposed hours with an automatic cut-off. Rural authorities in dark landscapes frequently resist lighting altogether.
Does biodiversity net gain apply to a garden court?
Householder applications are exempt from the biodiversity net gain requirement, so a statutory metric is not normally needed. Check the current exemptions before accepting a contractor's quotation either way, and note that protected species and tree protection obligations still apply regardless.
