High hedges, trees and light to a neighbouring house

If your neighbour's conifers have taken the light from your kitchen, the planning system cannot help you. The remedy is a high hedge complaint under Part 8 of the Anti-social Behaviour Act 2003, made to the council, and it only works if the hedge meets a fairly narrow legal description. A single large tree, however dark it makes your house, falls outside the regime entirely.

That distinction surprises people, and it is worth getting straight before you spend a fee. What follows is the position in England, where high hedge complaints are dealt with by the local authority with an appeal to the Secretary of State.

What the high hedge regime covers

The Act applies to a hedge that meets three tests at the same time.

• It is formed wholly or predominantly by a line of two or more trees or shrubs.
• Those trees or shrubs are evergreen or semi-evergreen.
• The hedge rises to a height of more than two metres above ground level, and it acts as a barrier to light or access to your property.

Every part of that description does work. Two or more means a single specimen is excluded. A line means a group or a copse may not qualify. Evergreen or semi-evergreen means a deciduous hedge such as beech or hornbeam is outside the regime even where it is dense and tall in summer. And more than two metres is measured above ground level at the hedge, which on sloping ground needs care.

The complaint has to concern a hedge on land adjoining your domestic property, and you have to be the owner or occupier of that property. A hedge in a park across the road is not within the regime, and neither is one that only blocks your view.

Making a complaint to the council

The council is the decision-maker, and it will refuse to consider a complaint until you have made reasonable efforts to settle the matter yourself.

So keep evidence of those efforts. A dated letter to the neighbour setting out the problem and what you are asking for, a note of any conversation, and any reply. Councils commonly ask to see this before they will accept the form, and the absence of it is the most common reason a complaint is rejected at the first stage.

A fee is payable and each council sets its own, so check the amount on your authority's website before you start. The fee is not refunded if the complaint fails, and it is not recoverable from the neighbour.

The council then assesses whether the hedge is adversely affecting the reasonable enjoyment of your property. It will look at the height, the orientation, the distance from your windows, the rooms affected, the loss of light and whether the hedge blocks access. Officers normally visit, and photographs taken at different times of year help.

Remedial notices, and what they cannot require

If the complaint succeeds the council issues a remedial notice. It specifies the initial action needed within a stated period and any preventative action needed afterwards to stop the problem recurring, which usually means a maintenance height.

The limits are firm. A notice cannot require the hedge to be removed, and it cannot require it to be reduced below two metres. So the realistic best outcome is a hedge maintained at a height somewhere above two metres that lets more light into your property, and anyone expecting the conifers to disappear will be disappointed.

Either party can appeal to the Secretary of State within the period stated on the notice, and in England those appeals are dealt with through the Planning Inspectorate. Failure to comply with a remedial notice is a criminal offence, and the council can carry out the work itself and recover the cost.

A notice is registered as a local land charge, so it binds a future owner of the land the hedge stands on. That is useful to know if the property changes hands mid-dispute.

Trees are a different problem with fewer answers

There is no statutory regime for loss of light from a tree. No complaint to the council, no remedial notice, no appeal.

What exists instead is a short list of partial remedies. You may cut back branches and roots that cross the boundary, at your own cost, and the cuttings belong to the tree owner so they must be offered back. A tree that is dangerous, or that is causing damage to your property, may support a claim in nuisance, which is a civil matter for a solicitor rather than the council. Rights to light in the legal sense attach to buildings and apertures over long periods, not to gardens or to trees, and there is no right to a view in English law.

Two things do involve the council. If the tree is protected by a Tree Preservation Order or stands in a conservation area, you need consent or must give notice before pruning, and an application can be made on amenity grounds including loss of light to your home. And if the tree is on council land, the authority's own tree policy governs what it will do, which is usually far less than residents hope.

Where a protected tree is in issue, the survey that informs any decision is a BS 5837 assessment, and our tree survey page explains what that covers and who prepares it.

When a development is the cause

Light lost to a new building is a planning matter, unlike light lost to a hedge, and the tests are entirely different.

For an application not yet decided, the relevant considerations are daylight and sunlight to existing habitable rooms, assessed against recognised methodology, and the separate questions of outlook and enclosure. The technical work belongs in a Daylight and Sunlight Assessment prepared by a suitably qualified consultant, and councils normally expect a qualified author for it. The overbearing effect of a tall or deep structure is assessed as its own head of harm, as our note on outlook and the overbearing test explains.

For a rear extension next door, the typical complaint combines loss of light with a sense of enclosure to a kitchen or dining room, and the way officers weigh that is set out in our note on rear extensions to a terraced house and neighbour amenity.

So the practical question to answer first is what is causing the loss. A building means planning. A hedge means Part 8. A tree means the civil law and, if it is protected, a consent application.

Where nothing can help

Some situations have no remedy, and knowing that saves money.

A deciduous hedge, however tall. A single tree, however large. A hedge under two metres. A loss of light to a garden rather than to the house, which the regime treats far more lightly than light to rooms. A hedge on land that does not adjoin your property. A view that has been built out or grown out.

In those cases the options are negotiation, a contribution towards the cost of the work you want done, or planting on your own side to change what you look at. Unsatisfying, and better to know early than after a fee and six months.

One honest uncertainty. Whether a hedge is adversely affecting the reasonable enjoyment of a property is a judgement for the council, and the outcome turns on the specific rooms, orientation and distances rather than on the height alone, so two similar-looking hedges can produce different decisions.
