CBS Property Maintenance, established in 2003 are your local Builders working in Greater London and the South East area. But don't just take our word for it. Our customers depend on us to provide a reliable and cost-effective service. We do our best to meet and exceed their high standards. Here's what our customers think about our efforts. ELECTRICS: We have Part P Engineers that can do a upgrade on general electrical maintenance to an entire rewire. Provide certificates for rented properties. GAS CENTRAL HEATING: We have 'Gas Safe' Engineers which cover maintenance, service and the renewal of an entire system. Who also carry out 'Corgi' Registered gas checks for Landlords annually and provide advice for a rental property to run economically and efficiently. ENERGY PERFORMANCE CERTIFICATES: Under government regulations (April 2007) all rental properties must now provide a certificate to show how 'energy efficient' a home is. We are also able to organise this for a Landlord and the certificate is for 10 years.
