Yes — and with a hedge, unlike a tree, height reduction is essentially the only way to do it. That makes the question simpler, and it moves the conversation straight to how far the hedge can come down.
Why a hedge cannot be thinned instead
With a shading tree there are options: lift the canopy so light comes in underneath, or thin it so light filters through. Both leave the tree the same size.
How much light a reduction gives back
| What's in shade | What reduction achieves |
|---|---|
| A border right against the hedge | A lot — that strip gets sun back |
| A patio a few metres away | A lot, particularly morning or evening |
| The middle of the garden | Noticeable, depending on aspect |
| A ground-floor window | Depends on distance; often substantial |
| An upstairs window | Less — the hedge may not be the cause |
A hedge shades a distance roughly related to its height, and most in the morning and evening when the sun is low. So taking three feet off moves the shade line in by a meaningful distance at the times of day people actually use a garden.
What limits how far it can go
| Species | How far down |
|---|---|
| Yew | Into bare wood — recovers reliably |
| Beech / hornbeam | To the framework |
| Hawthorn / hazel | Very hard |
| Laurel | Hard — regrows vigorously |
| Privet | Hard — very forgiving |
| Holly | Hard, but slow to fill back in |
| Leylandii, Lawson, thuja | Green growth only |
On the last row, cutting past the green leaves bare brown wood that will never green up. Push a hand into the top of the hedge and find how far the green goes — that is the limit, whatever figure you had in mind.
The good news for a light problem specifically: the green on a conifer hedge is almost always deepest on the top, because that is where the light falls. So height reduction — which is exactly what you want — is usually more achievable than width reduction.
Do it in late winter if the point is summer light
Timing matters more than usual when light is the objective. A hard reduction on a broadleaf hedge belongs in late winter, before growth starts, so the hedge has the whole season to recover.
Done then, the light is back for the summer. Decided in June, you are choosing between a compromised cut now and waiting a year — which is worth knowing when the garden is at its gloomiest and the temptation is to act immediately.
If it is a neighbour's hedge
Rights of light concern buildings and windows rather than hedges. What does exist is the high hedge provision: Part 8 of the Anti-social Behaviour Act 2003 lets you complain to Tewkesbury Borough Council about a neighbour's hedge if it is a line of two or more evergreens over two metres acting as a barrier to light or access.
The limits matter. Conifers, laurel and privet are in scope; beech and hornbeam, being deciduous, are not, and neither is a single tree however large. You must have genuinely tried to resolve it directly first. There is a fee. And the council cannot require the hedge below two metres or order it removed.
In practice a conversation and a shared quote settles this faster and more cheaply than a complaint, and leaves both gardens in a better state.
Keeping the light once you have it
Ask what height the hedge has been cut to, and have it maintained at that height annually. A hedge reduced once and then left simply grows back to where it was — which is how people end up paying for the same reduction twice.
