Had a call from a relative today - it sounds like the immersion heater has
packed up. I will go and confirm, but I don't want to get into replacing it
(too much risk of sods law kicking in and the thing will be stuck and the
tank will rip!)


Any clues for a rule of thumb charge for an Electrician to replace the
immersion heater? (They seem to cost between £14 and £20 to buy)
