The Building (Amendment) (Wales) Regulations 2018

These Regulations amend the Building Regulations 2010 (“the 2010 Regulations”).

Regulation 3(1) amends regulation 36 (water efficiency of new dwellings) to introduce a new requirement that where a dwelling is erected the potential consumption of wholesome water by persons occupying the dwelling must not exceed 110 litres per person per day. The current requirement of 125 litres remains where there is a material change of use such that a building is used as a dwelling or contains a flat, in either case where previously it did not.
