Statutory regulations and laws are legal requirements, non-statutory regulations are not law but can be used in a court of law as evidence to claim compliance with a statutory requirement.
Failure to comply with the Electrical Regulations may constitute a criminal offence under the Consumer Protection Act 1987 that carries a maximum penalty on summary conviction of a £20000 fine and/or six months imprisonment.
This Legislation means that Landlords have a legal obligation and a duty of care to tenants to ensure that the electrical installation and the electrical equipment supplied is safe.
The only way to prove an electrical installation is fit for continued use is to have an Electrical Installation Condition Report (aka Landlord Certificate) carried out.
