Hello Would you need a particular qualification to install an unvented tank hot water system including boiler vessels etc etc. Is a gas safe person qualified enough?
Spot on. Gas safe register will show if firm has G3 cert, there is anonther link, & I cannot remember it,or find it. https://www.gassaferegister.co.uk/find-an-engineer/
baracus,if you have some plumbing experience,some common sense then you can do the g3 course and assessment,same day at a cost of around £300+vat then you can install and do the periodic servicing,which those cylinders require. handy if you live in an estate with many unvented cylinders dont forget my 10%
