Electrical installation safety – Direct.gov
At the beginning of each new tenancy, you should ensure that electrical installations – like fixed wiring – are safe and well maintained. Any electrical appliances you supply to tenants – like cookers and kettles – should be safe for them to use.
You should carry out regular inspections of fixed electrical installations – like sockets and light fittings – every five years. You should also arrange, at least once a year, for a qualified electrician to carry out a portable appliance testing (PAT) safety test on any portable electrical equipment you provide for tenants, like kettles. The PAT tester will give you a dated certificate and put stickers on the plugs of appliances to show that they are safe.
