You need a River Thames accommodation licence to build, change or keep any structure:
- on, in or over the river, eg jetty, boom, pontoon, piling
- that cuts into the river bank, eg dock, slipway
It is valid until you move or change the structure.
You must display the accommodation licence plate on the structure.
There is an annual fee for the licence, which runs from 29 September each year.
Licences can’t be transferred. You must get a licence if you buy or live in a property with a structure.
Before you build a new structure or change an existing structure, contact the Environment Agency to discuss your plans.
