In this section "combined instrument" means an instrument containing (whether alone or with other provision)—
provision made under section 1(1) of the Building Act 1984 (building regulations), and
provision made under section 2(2) of the European Communities Act 1972 (provision implementing EU obligations etc).
Regulations under section 1(1) of the Building Act 1984 may revoke a combined instrument so far as it is made under section 2(2) of the European Communities Act 1972.
Nothing in paragraph 13 or 14 of Schedule 8 to the European Union (Withdrawal) Act 2018 (procedure etc for SIs amending or revoking regulations etc made under section 2(2) of the 1972 Act) is to be read as applying to a statutory instrument that amends a combined instrument so far as the combined instrument is made under section 2(2) of the European Communities Act 1972.
