Electricity Regulations 1947

A person to whom has been issued a certificate of approval in respect of an electrical appliance may, if the Director in writing so approves, alter the design, materials or construction of the electrical appliance in any particular, but the approval shall be given only after examination of a sample or samples of the altered electrical appliance. The Director shall cause to be endorsed on the relevant certificate of approval particulars of the alteration or alterations so approved and thereupon the electrical appliance so altered shall be approved and shall be deemed to be the approved electrical appliance to which that certificate relates. The applicant shall pay to the Director any fees demanded by the Director for any examination under this regulation and, where the Director determines that any testing may be required as a result of any alteration in design, materials or construction, the cost of that testing shall also be paid for by the applicant.

If the Director does not approve the alteration of the electrical appliance in any particular the Director shall so notify in writing the person applying for the approval.

No person shall sell or hire or expose for sale or hire or advertise for sale or hire any electrical appliance purporting to be identical with or similar to an electrical appliance for which a certificate of approval has been issued, but which in the opinion of the Director is not identical with or similar to the approved electrical appliance by reason of change of design, materials or construction.
