You can legally cut a garden hedge at any time of year, but under the Wildlife and Countryside Act 1981 it is an offence to damage or destroy a wild bird's nest while it is being built or in use. Because most birds nest between March and August, the safest time to cut hedges is from September to February.
The best time to cut a hedge
| When | What to do |
|---|---|
| September to February | Main cut and any heavy reduction. Nesting season is over. |
| March to August | Avoid cutting. If you must, only a light trim after checking carefully for nests. |
Can I trim my hedge during nesting season?
You can, but only if you are sure there are no active nests. Look through the hedge slowly from several sides, watch for birds flying in and out, and listen for chicks. If you find an active nest, leave that part of the hedge alone until the young have left. Damaging an active nest is an offence, so always check before you cut.
What about a neighbour's tall hedge?
If a neighbour's hedge blocks your light, talk to them first. If that fails, you may be able to complain to your council under the high hedges rules. These apply to a line of two or more mostly evergreen trees or shrubs over 2 metres tall. The council usually charges a fee, and it can order the hedge to be reduced, but not removed or cut below 2 metres.
