Brentford Dock Marina is situated on the tidal River Thames at the mouth of the Grand Union Canal, between Kew Bridge and Isleworth, in the southern part of Brentford, Middlesex. Once a working dock, today, it is one of London's undiscovered treasures.

The Marina is exceptionally well located for boat owners in West London that are looking for mooring on the Thames.

All of the above are wholly owned by the shareholders (property owners) of Brentford Dock, that is, the owner of each flat, maisonette or house also owns one-five-hundred-and-ninetieth (1/590) of the marina, marina club and the Spar shop.

The Lock

The Brentford Marina Lock can be opened from approximately 2½ hours before and after high water. Boats with deeper draughts may only be able to enter and leave between approximately 2 hours before and after high water.

The Lock is hydraulic and has working dimensions of approximately 9.8 metres (32 feet) and 4.8 metres (16 feet).

Boats over 32 feet enter at high water on free-flow by prior arrangement.

On our part of the River Thames the tide takes approximately 8 hours to "go out" and 4 hours to "come in". During spring tides (which occur every fortnight) the river level can rise over 7 metres (24 ft) in 4 hours, i.e., 1.8 metres or 6 ft per hour.

Free-flow can be used when tide is higher than 6.7 meters and approximately 30 minutes before and 15 minutes after high tide.


  • Very secure premises - The main pontoon is locked, access by swipe card only, 24 hour Estate/Dock patrol.
  • Electricity at each berth and water points on pontoon.
  • Showers, toilets and waste disposal facilities, (no oil disposal).
  • For berth-holders arriving outside locking times there is a 15 metre waiting pontoon in the Thames.
