Why Gas Safety Certification is Essential
Protect Tenants from Carbon Monoxide And Gas Leaks: Carbon monoxide is a poisonous gas. It is colourless and odourless. Our inspections will ensure all gas appliances burn safely, flues are clear and ventilation is adequate reducing the risk of leaks and ensuring a safe living environment.
Legal Obligations for Landlords: Landlords are required by law to carry out regular annual gas safety inspections and to provide the tenant with a copy of the CP12 certificate within 28 days of the inspection or before new tenants move in. Legal consequences are to be avoided by compliance.
Insurance & Liability Considerations: If you have a valid CP12 gas safe certificate, you will still be covered by your insurance policy. Otherwise, landlords risk being sued and having to pay compensation if accidents do happen.
Risk of Non-Compliance and Penalties: If you do not keep a valid CP12 you could face fines of up to £6,000 for each breach, or even imprisonment in extreme cases. Liviosiv reduces these risks with inspections at the right moment and with digital certificates.
