Testing For Businesses
What the regulations say:
"As may be necessary to prevent danger, all systems shall be maintained so as to prevent, so far as is reasonably practicable, such danger."
The Health & Safety at Work Act 1974 puts a duty of care upon both employer and employee to ensure the safety of all persons using the work premises.
The regular inspection and testing of electrical installations and equipment is an essential part of any maintenance programme. All businesses have a duty of care to ensure that the environment employees are working within and any equipment being used is safe. The best way of achieving this is through periodic inspections and testing and PAT testing.
Testing For Landlords
It's not just business and employees that require testing.
The same legislation applies for landlords. As a landlord you have a duty to prevent any harm to tenants from the electrical installation of a property and from any appliances that you supply with the rental property. You are required to have an up to date periodic inspection report of the property and ensure appliances included in the lease of the property, such as washing machines, fridge freezers etc, are certified as safe.
You as the landlord are held responsible and liable for any injury or damage resulting from unsafe electrical installations and appliances. It is now widely accepted in the letting industry that the only safe way to ensure safety and to avoid the risk of being accused of neglecting your 'duty of care' is to arrange such an inspection and report.
