Birds Nesting in Your Roofline: What UK Law Actually Says

Updated 14 September 2026 · 4 min read

Starlings, jackdaws and house sparrows regularly nest in gaps behind soffits, in chimney pots, and under loose roof tiles - and because all wild birds are legally protected while nesting, the timing of any work matters as much as the work itself.

The legal position

Under the Wildlife and Countryside Act 1981, it’s an offence to intentionally take, damage or destroy the nest of any wild bird while it’s being built or in use, and this applies across the whole UK - not just rare species. If there are eggs or chicks present, or the parents are still actively building, the nest has to be left alone. Once birds have fledged and the nest is no longer in use, it can be removed without a licence.

What this means for timing roofline work

• The main UK bird breeding season runs roughly March to August, though jackdaws and starlings can nest earlier or run later depending on conditions
• If a soffit or fascia repair is going to disturb an active nest, the sensible approach is to wait until the birds have fledged, not push ahead and risk an offence
• Winter and early spring, before nesting starts, is genuinely the easiest time to carry out repairs on a roofline with a known bird problem

When removal during breeding season might be justified

If there’s a genuine health and safety issue - structural damage, a blocked flue, or a fire risk from nesting material - a licence to remove an active nest can sometimes be obtained, but this needs to go through the proper licensing route rather than being decided informally by whoever’s doing the work.

Preventing nesting in the first place

Once a nest site has been vacated outside breeding season, the actual fix is usually straightforward: proper soffit ventilation grilles that let air through but keep birds out, a chimney cowl for pots being used as nest sites, and sealing gaps that let birds behind fascias in the first place. Prevention after the season, not disturbance during it, is the right order of operations.
