Gas & Boiler Checks

When you are renting a property, you are legally responsible for your tenants in regard to gas safety. You are required to repair and maintain gas pipeworks and appliances as well as ensuring an annual gas safety check is completed. Our gas engineers are able to install, repair and maintain all aspects of your property's gas work, giving both you and your tenants peace of mind that their home is safe.

Electrical Checks

As a landlord, you are legally required to ensure your property is safe for the duration of the tenancy. To do so, we recommend periodic inspections of the property's electrics. You must also ensure all appliances are safe with the CE markings. Our friendly and professional team of qualified electrical engineers can help you meet these requirements by undertaking the relevant safety checks and maintenance as well as providing safe electrical installations.

Energy Certificates

Energy Performance Certificates (EPCs) are a rating scheme designed to provide a summary of a building's energy efficiency. Given a rating between A and G, an EPC gives an indication of how energy efficient a property is as well as how you can improve it. It is now a legal requirement for all properties that are marketed for sale or to let carry a valid EPC. With Williams SW Ltd in Bristol, we can provide you with a valid energy certicate for all of your properties.
