The Electricity at Work regulations 1989 (EAW Regulations) apply to almost all places of work. 
HSG85 is a generic Guidance Document covering safe working practices for work on electrical equipment and is produced to support the Regulations.

Regulation 12

“isolation” means the disconnection and separation of the electrical equipment from every source of electrical energy in such a way that this disconnection and separation is secure.

Regulation 13

Adequate provisions shall be taken to prevent electrical equipment, which has been made dead in order to prevent danger while work is being carried out on or near that equipment, from being electrically charged during that work if danger may thereby arise.

Provision and Use of Work Equipment Regulations (PUWER) 1998

Regulation 19

Every employer shall ensure, that where appropriate, work equipment is provided with suitable means to isolate it from all its sources of energy. Every employer shall take appropriate measures to ensure that reconnection of any energy source to work equipment does not expose any person using the equipment to any risk to his health or safety.
