If you are a plumber you should relax and look forward to a host of urgent telephone calls in the next few weeks as, in the north at least, winter is arriving and many boilers will fail.
If you are not skilled in the plumbing black arts you may want to consider protecting you boiler against breakdowns. Yes it is a form of insurance and, as times are tough, it is one of the things we consider dropping at times. Remember if you boiler fails you could have a bill in the hundreds of pounds.
The decision is up to you and will be influenced by the age and condition of your boiler.
