DD Willson provides boiler installation and service, providing you with Gas Safety Certificates. Any gas appliance in your home can produce carbon monoxide (CO), a highly poisonous gas which occurs when natural gas or liquid petroleum gas (LPG) doesn’t burn as it should.

This is the result of a gas appliance being improperly fitted, repaired or maintained, or when vents, flues or chimneys have become blocked - and that’s why it’s so important to have all of your gas appliances checked once a year by a Gas Safe registered engineer.
