Mr. Wills
Land Registry requires the use of metric measurements on any documents dated on or after 1 October 1995. Any imperial measurements in such documents must appear as supplementary indications only and will usually be placed in brackets, for example, 22.86 m (75 feet).
Land Registry similarly only uses imperial units of measurement on the register and title plan as supplementary indications (in brackets) or where they are included in a verbatim extract from a deed dated prior to 1 October 1995.
