Boaters intending to pass through the tunnel must book their tunnel passage at least 3 days in advance by phoning British Waterways, Yorkshire Area (01977 554351). Boaters are advised to book further ahead during busy periods.

At the time of writing, the charge for boat passage is free which includes up to 4 crew members (£35.00 for short-term license holders). Additional crew members are charged at £8.00 each. Please check with British Waterways website in case prices have changed.

Boaters should remove chimneys, side navigation lights, aerials, etc. prior to passage. BW staff will cover boat roofs with rubber sheets to protect the roof paintwork from damage from the rough sections of tunnel wall.

The passenger module includes toilet facilities. Passengers are advised to take warm clothing with them into the tunnel.

Due to difficulties with lock mechanisms and problems with loss of water, navigation of both the Marsden and Diggle Lock flights is restricted. The bottom lock on each flight is kept locked except when British Waterways staff are in attendance to assist passage through the locks.

Only boats booked to pass through Standedge Tunnel are allowed up the Diggle lock flight. For a trial period, boats not passing through the tunnel may come up the Marsden flight and moor at Marsden for a couple of days. These passages must be booked in advance. See the British Waterways website for the latest information or phone 01977 554351.
