Did you know that…?

The properties you let are legally required to have all gas appliances checked every 12 months and that a Gas Safety Record should be at the property at all times?

Assert Heating Services cover all gas and plumbing safety checks, according to the current regulations. Our comprehensive landlord services include gas safety checks and yearly gas certifications. As a landlord, you must ensure gas fittings and flues are maintained in a safe condition, and that an annual safety check is carried out on each gas appliance and flue. Safe tenants are happy tenants.

  • Inspection of your boiler and all the gas pipework
