The High Hedges Act only covers hedges, not one tree. Here's what options actually exist when a single tree next door is shading your garden.
A neighbour's leylandii row and a neighbour's single oak tree feel like the same problem when they're both blocking your afternoon light, but they sit in completely different parts of the law. The High Hedges Act 2003 gives you a formal complaint route against a hedge. It gives you nothing at all against a single tree, no matter how large it's grown.
The Act defines a high hedge as a line of two or more trees or shrubs, mostly evergreen or semi-evergreen, forming a barrier to light or access above two metres. A lone specimen tree, whatever its height or species, simply doesn't meet that definition, so the council complaint process covered in our leylandii hedge guide isn't available for it. This catches people out because the two situations look identical from the garden.
English law recognises a right to light for certain windows that have enjoyed direct light for twenty years or more, under the Prescription Act 1832, but that right protects a window in a building, not open garden space. A tree shading a lawn or a vegetable patch, however much it affects your enjoyment of the garden, doesn't engage this right at all. Taking a neighbour to court over ordinary shade from a tree they're entitled to grow rarely succeeds, since proving legal nuisance requires more than reduced light, generally a substantial and unreasonable interference judged against what's normal between neighbours.
Common law gives you the right to cut back branches and roots that cross onto your side of the boundary, back to the boundary line itself, without asking the tree's owner first. This comes from a long-established principle, confirmed in the 1894 case Lemmon v Webb, and it still applies today. It doesn't give you the right to enter the neighbour's land to do the cutting, to cut beyond the boundary line, or to do anything that kills or seriously damages the tree. Anything you cut technically belongs to the tree's owner, so it's good practice, though not a legal requirement, to offer the branches back rather than binning them, and to let the neighbour know before you start rather than after.
None of this changes if the tree carries a Tree Preservation Order or stands in a conservation area. Cutting back an overhanging branch on a protected tree still needs the same consent as any other work on it, covered in our guide to Tree Preservation Orders, even though the branch is over your boundary. Checking the register first avoids finding out the hard way that a routine trim was actually an offence.
A direct conversation with the neighbour, ideally before things feel adversarial, resolves more of these situations than any legal route does. Crown reduction or crown lifting can bring meaningful extra light into a garden without removing a tree the neighbour has no legal obligation to take down, and it's often a smaller ask than requesting removal outright. Our crown reduction and pruning service covers this end of the job, whether the tree in question is yours or you're suggesting it as a compromise to a neighbour.

Not through any formal legal process, no. The High Hedges Act only covers hedges of two or more trees or shrubs, not a single specimen tree, and there's no general right to light over open garden space. Your realistic options are a direct conversation with the neighbour or, for anything crossing your boundary, cutting the overhanging growth back yourself.
Yes, back to the boundary line, under a long-standing common law right. You can't enter the neighbour's land to do it, can't cut beyond the boundary, and can't do anything that seriously damages or kills the tree. It's good manners to let them know and offer the cuttings back, even though neither is strictly required.
Yes. The right to cut overhanging branches back to the boundary doesn't override TPO consent requirements. If the tree carries an order or sits in a conservation area, the same consent process applies to a boundary trim as to any other work on it.
