Do you legally need a professional or a licence?
Some home and garden jobs are tied to UK law: disturbing bats or nesting birds, working on a tree with a preservation order, disposing of Japanese knotweed waste, and using professional rodenticides all carry legal duties, and getting them wrong can be a criminal offence. Pick your job below to see whether DIY is lawful, when you need a licence or consent, and who to contact. This is general information, not legal advice.
Many trades gloss over the law because it complicates the sale. Check it yourself before you act or pay anyone.
What is the job?
General information only, NOT legal advice and not exhaustive. Always confirm with your local authority, the relevant statutory body or a solicitor before acting.
What this gate is based on (methodology)
Each answer summarises the relevant UK statutory position and links to the primary gov.uk or HSE source:
- Bats and nesting birds: protected, so disturbance can require a licence and is otherwise an offence (gov.uk wildlife licences).
- Japanese knotweed: not illegal to have, but you must not let it spread and the waste is controlled (gov.uk).
- Protected trees: a Tree Preservation Order or conservation area means council consent is needed first (gov.uk).
- Rodenticides: professional-strength products are tightly regulated to protect wildlife and pets (HSE).
The tool routes, it does not rule on your specific case. It deliberately errs towards "check first" because the offences are real. No legal advice is given.
Frequently asked questions
Why does the law matter for a home job?
Because some common jobs touch protected wildlife or controlled substances, and doing them wrong is a criminal offence, not just a fine on paper. Disturbing bats or nesting birds, working on a protected tree, or misusing professional rodenticides can all carry prosecution. Tradespeople sometimes skip this because it complicates the sale, so it pays to check first.
Is this legal advice?
No. This tool is general information to point you at the correct gov.uk guidance and the right named body for your situation. It is not legal advice and does not cover every case. For anything serious or uncertain, contact your local authority, the relevant statutory body, or a solicitor.
What if I am not sure whether something is protected?
Assume it might be and check before you act. For bats and nesting birds, contact the relevant statutory nature body before any work. For trees, ask your council about a Tree Preservation Order or conservation area. For knotweed waste, follow the controlled-waste rules on gov.uk. Acting first and asking later is what leads to offences.
