When a neighbour's tree is the cause of the shading

If a neighbour's tree is blocking your light, planning law will not help you and neither will the law of rights of light. An easement of light can only be acquired against a building or structure, so a tree blocking light to a window creates no legal right you can enforce, however old the tree and however dark the room. Neighbour tree shading light complaints have exactly one statutory route in England, and it covers evergreen hedges rather than trees.

That route is the high hedges procedure, and it is narrower than most people expect.

No general right to light from a tree

Rights of light are property rights acquired over time in respect of light reaching a defined aperture, and the obstruction has to be a building or a structure. Vegetation does not count. A beech that has grown over 40 years to shade your kitchen gives you no claim, and nor does a leylandii screen planted the year you moved in.

Planning control is equally unhelpful. Planning bites on development, which means on building work and changes of use. A tree that is simply growing is not development, so there is nothing for the council's planning service to regulate and nothing to object to.

Loss of light from vegetation is also not a statutory nuisance under the Environmental Protection Act 1990, because the categories in that Act do not extend to it. People frequently try that route and are turned away.

So the honest starting position is that most tree shading disputes have no legal remedy at all, and the practical answers are negotiation, a contribution towards pruning, or the high hedges procedure where the facts fit it.

The high hedges complaint route

Part 8 of the Anti-social Behaviour Act 2003 lets you complain to the local authority about a high hedge that is affecting the reasonable enjoyment of your property.

The definition is tight. A high hedge means a line of two or more evergreen or semi-evergreen trees or shrubs, rising more than two metres above ground level, that forms a barrier to light or access. Each element of that definition excludes a common complaint:

• A single tree, however large, is outside the regime entirely.
• A deciduous hedge of beech, hawthorn or hornbeam is outside it, because the trees must be evergreen or semi-evergreen.
• A hedge of two metres or less cannot be the subject of a complaint.
• A hedge that is not a line, such as a group of shrubs in a border, does not qualify.

Where the facts do fit, the council assesses whether the hedge is adversely affecting reasonable enjoyment, taking account of the height, the orientation, the distance to your property and the character of the area. It balances your amenity against the hedge owner's, which means a decision that the hedge must come down to two metres is not the usual outcome.

What the complaint procedure requires first

You have to try to sort it out yourself before the council will take the complaint. That is not a formality. The complaint form asks for evidence of the steps you took, and a council will reject a complaint where no attempt at resolution is documented.

Do it in a way that creates a record:

1. Write to the hedge owner, politely, describing the effect on specific rooms and the garden, and proposing a height.
2. Keep a copy, and allow a reasonable period for a reply.
3. Write again if there is no response, and offer to share or meet the cost of the work.
4. Consider mediation, which some councils will point you towards and which is far quicker than the statutory route.
5. Keep photographs with dates showing the hedge and the affected rooms.

Councils charge a fee for a high hedges complaint, set locally, and it is not trivial. The fee is not usually refundable if the complaint fails, which is another reason to exhaust negotiation.

Evergreen hedges over two metres

If the council accepts the complaint, it investigates and may issue a remedial notice requiring the owner to reduce the hedge and to maintain it at a stated height.

Two limits matter. The council cannot require the hedge to be reduced below two metres, so a complaint hoping for removal will be disappointed. And the notice cannot require the hedge to be grubbed out, only reduced and maintained.

Either party may appeal a remedial notice to the Secretary of State, and those appeals are decided by the Planning Inspectorate in writing within a set period after the notice. Failure to comply with a notice that has taken effect is an offence, and the council can carry out the work and recover the cost.

The whole process commonly takes several months. Set expectations accordingly.

Trees that are protected and cannot be cut

Before anyone touches anything, check the tree's planning status. A tree covered by a Tree Preservation Order cannot be pruned or felled without the council's consent, and in a conservation area six weeks notice is required before work on most trees. That applies to the owner and to you.

This cuts both ways in a shading dispute. If your neighbour's shading tree is protected, the council will not consent to a reduction merely because it makes your kitchen dark, and amenity value is the reason the Order exists. If the tree is unprotected and your neighbour agrees to a reduction, the work can proceed without any planning involvement at all.

Where the shading argument arises as part of a development proposal rather than a neighbour dispute, the tree becomes a constraint to be surveyed. A Tree Survey to BS 5837:2012 records the shade pattern alongside the root protection areas, and that is the document an architect works from.

Overhanging branches and abatement

At common law you may cut back branches and roots that cross your boundary, to the boundary line and no further. That right of abatement is useful and frequently misunderstood.

Four rules govern it. You may not enter the neighbour's land to do the work without permission. You may not cut beyond the boundary, even if the remaining shape looks odd. The cuttings and any fruit belong to the tree owner, so offer them back rather than throwing them over the fence. And if the tree is protected, you need consent or notice first, because abatement is no defence to an offence under the Tree Preservation Regulations.

Abatement does not help with shading from a tree whose crown sits entirely on the neighbour's side, which is the usual situation.

Where planning has no role at all

Planning only engages when development is proposed, and then the questions change completely. If the neighbour applies to build something that overshadows you, daylight and sunlight become material considerations and a Daylight and Sunlight Assessment against BRE 209 is the evidence. If sunlight to your garden is the issue, an Overshadowing Study with shadow plots at the equinox and the solstices is the right document, and the approach is the same one described in our note on daylight to a single storey rear extension on a bungalow.

Existing trees are treated as part of the baseline in those assessments. BRE 209 guidance on site layout deals with obstruction by buildings, and a daylight consultant will usually model the trees as they are rather than as they might be cut back, which can work in an applicant's favour.

For growers and anyone whose use depends on light, the commercial version of this problem is covered in our note on loss of light to a glasshouse or nursery.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
