We work for a number of letting agents on a regular basis. It is the Landlord’s responsibility to ensure that the electrical installation and appliances provided by the landlord are safe. It is recommended that fixed wiring be tested every 5 years. Houses in multiple occupation must be tested every 5 years. PAT testing is left to the landlord’s discretion. In the case of houses in multiple occupation (i.e. all HMOs; not just licensable HMOs) the landlord is obligated under management regulations to ensure all fire alarms are in proper working order.
