Gas safety inspection & Boiler Servicing / installation in London, Kent, and Surrey
Having your gas boiler serviced annually , ensures that it runs efficiently and economically and above all else is that it is safe to do so.
This not only helps to keep your gas bills down, but also helps to reduce harmful co2 emissions which harm the atmosphere and lead to global warming and lastly if you are renting your property, then you will also need to show that your appliances have been serviced regularly. When servicing a boiler we carry out the following:- Clean burners and heat exchanger. Check gas burner pressure. Check Co2 and Co levels with a Combustion Analyser. Check flue. Visual check of appliance seals and casing. Flame picture check. Correct operation of safety devices. Water pressure. Check expansion vessel and pressure release valve. Visual check for leaks. Operational check. NOW YOU CAN PUT YOUR FEET UP IN FRONT OF THE FIRE, KNOWING YOU WILL BE NICE AND WARM AND HAVE LASHINGS OF HOT WATER OR IF YOU ARE A LANDLORD THE TENANTS WILL NOT BE CALLING YOU AT 3 am COMPLAINING THAT THEY ARE COLD. NOW THAT IS PEACE OF MIND. |
We service and install all makes of gas boilers.
Please Note that a Landlord Must Maintain a Gas Boiler under the Gas Installation & Use Regulations and keep a copy of any maintenance which has been carried out. To meet this requirement we recommend that you service your boiler every 12 months, a Landlord has just been fined £5000 pounds and been given a suspended 2 year prison sentence for failing to do this (he did have a gas safety certificate). So be warned, do not let it happen to you. See our news section for more details on Landlords who have been fined or imprisoned.
If you have a old boiler then it would be a good idea to upgrade it to a new high efficiency condensing model. We install all the latest models, give us a call to arrange a free quotation you could save upto 50% off your gas bills.
