This listing gives the British Waterways/Canal & River Trust equivalent to the ELR system. Information is derived from records quoting codes in use and there are thus some gaps for which translations are unknown (the codes themselves are known). There are also canals for which the code is not known. In both cases, further information would be welcome.
