Landlord Gas Safety Certificate (CP12) in London
Every landlord renting out a property in England with a gas appliance is legally required to have a Gas Safety Record (formerly known as a CP12) every twelve months. Ilir has been doing landlord checks across London since 2004. Same-day appointments are usually possible, certificates emailed to you within 24 hours, and multi-property discounts apply if you manage more than one address. He’ll also flag any non-compliant appliances honestly so you can address them before a tenant raises a complaint.
