I have just had a new pump fitted to my central heating system and all works perfectly , hot water and central heating , but the plumber said he had a shock when the electrics were switched off , an electrician has also had a shock from the boiler when working on it and cannot work out what the problem is . Can anyone help me please. desmo11225

something - perhaps the immersion heater, is leaking to earth and the plumbing is not bonded to mains earth.
Or the plumber is a bit of a live wire and the plumbing IS earthed!

Suggest that you find a better electrician.
Could be wired wrongly! *All* the electrics for the heating system should be wired via a single isolator - enabling the whole system to be isolated when switched off. But if the system is powered from multiple supplies, parts could still be live when other parts are switched off.
