    What do I do if I smell a gas leak?

    Turn off gas at the gas meter shut-off valve. The shut-off valve is normally located near your gas meter. It is an industry safety requirement that all gas service shut-off valves must have a handle fitted to them to stop the gas supply. Give the handle a quarter turn in either direction; the valve is closed when the handle is crosswise to the pipe.
    Contact Wales & West Utilities on 0800 111 999. Then contact a Gas Safe registered engineer.
    Open doors and windows to let air in.
    Do not turn on any lights or electrical appliances.
    Do not light any matches, lighters or other flame.

    How do I prevent freezing?

    Insulate as much pipe work in your home as possible. 
    If you're going away on holiday turn off your stop cock. 
    Turn off your outside tap over winter or, if unable to do so then fit an outside tap cover. 

    What do I do if I smell an oil leak?

    Stop the oil from entering the property by turning it off at the tank.
    Contact your local Oftec registered engineer.
    If a major spillage then please call the environmental agency on
    0800 80 70 60.

    What do I do if I find a water leak?

    Turn off your stop cock - this is usually found under the kitchen sink, you will need to turn this clockwise to switch it off.
    If the stop cock fails to stop the water flow then you will need to switch off your water supply to the property - this is normally and the bottom of your drive or in the roadway. There should be a plastic key in there to turn it off.

    How often should I service my boiler?

    Gas boilers - these should be serviced yearly to keep your boiler under warranty and ensure that they are safe and working efficiently. 

    Oil boilers - servicing your boiler not only keeps it functioning correctly, an annual service will also ensure that no hazards to health arise from poor combustion. It is imperative that the nozzle on oil boilers is changed yearly to stop this risk and prolong your oil boilers life. 

    Gas and Oil boilers should be turned off 1 hour before the service
