Don't panic as a consumer and not a plumber I for one would not go with Tesco I like to know my plumber we have a good plumber we can call on who is oftec registered and now knows our boiler. If you go with someone like Tesco chances are they would come and fit your boiler, then you would have a problem and a different plumber would turn up and so you would end up going round and round and round, at least when you stick to a good plumber you know you will get a good service as he already is familiar with your layout.
