Using the locks

There will be assisted passage at some lock sites during lock keeper hours of duty. When assisted passage is not offered, locks will be self service on public power where public power is available.

Lock keepers work at Environment Agency locks to help boaters through the lock. You can also operate the lock yourself when a lock keeper is not there. To find out whether there will be a lock keeper on duty at the lock you are visiting check our River Thames lock keeper service page.

Full details of the service lock keepers offer on the River Thames are in the River Thames Customer Charter.

Teddington Lock has a 24 hour service all year.

At all other locks, you need to operate the lock yourself when the blue ‘self service’ signs are displayed.

Operating the lock yourself

When lock keepers are not available you may work the lock yourself, at your own risk. Some locks have power, which makes them easier to operate.

Operating instructions are posted at locks. Read the operating instructions before you operate the lock.

If you are operating the lock yourself:

  • stay close to the sluice controls while the sluices are in operation
  • close the lock gates properly before slowly opening the sluices to fill or empty the lock
  • leave the lock empty and shut the gates after use - there is often a public right of way over the gates

In an emergency you should close all sluices before dealing with the situation. Emergency contact details are displayed at each lock.

Camping at lock sites

Some Environment Agency lock sites on the River Thames have camping facilities. When planning to camp at an Environment Agency camp site, you will need to check the access routes. Many are only accessible by boat or on foot. Parking is not available at all lock camp sites.

Camping is available at the following sites between the stated dates:

  • Rushey – 1 April to 31 October 2022
  • Shifford – closed until further notice
  • Pinkhill – 1 April to 30 September 2022
  • Eynsham – all year
  • Days – closed until further notice
  • Hurley – closed to casual campers
  • Cookham – closed

To ask about availability, call 03708 506 506 or email WaterwaysThames@environment-agency.gov.uk. State the dates and campsite you are interested in and the number of people and tents you want to book for. We will respond to your enquiry within 10 working days to confirm your booking. Please do not contact the Lock Office directly.

Find out about call charges.

Payment can be made on arrival at site during lock keeper hours of duty. You can pay by cash, cheque or credit or debit card.

Short stay mooring

Unless signs state otherwise, you are allowed to moor for up to 24 hours at Environment Agency short stay moorings.

You may have to pay a fee at some sites, either for mooring at any time, or after an initial free period.

Signs will usually show any applicable conditions and charges payable. By mooring, you are agreeing to them.

Call 03708 506 506 if you have any queries, including if you want to pre-book a short stay mooring. Please note, pre-booking is only available at selected locks.

Find out about call charges.

Additional charges and penalties

Additional charges and penalties may apply if you do not comply with conditions of use. Penalties could include:

  • suspension of your boat registration
  • removal of your boat under court order (at the owner’s expense)

If we have issued warnings for the current river conditions that advise you not to navigate, these penalties will not apply. You should plan to move your boat from the mooring when it is safe to do so.

    Base mooring at lock sites

    If you keep, or mainly use, your boat on the River Thames you must have a proper base mooring. This is somewhere to put your boat when you are not cruising, such as a marina berth.

    If you live on your boat as your only place of residence, you need to have an approved residential mooring.

    The Environment Agency offers base mooring at some lock sites. None of these sites allow residential mooring.
