Having just moved into our flat we spotted a leak coming from the bottom of the hot water tank in the airing cupboard. Although we thought at first it was just teh sealant leaking around where the immersion filament entered at the bottom of the tank, our plumber informed us the copper tank had a leak in it and would need replacing. We have been quoted a total of approx. Â£830 for this work to be done, including labour - does this seem reasonable? The plumber also stated that the lifespan of these tanks is only 15 - 20 years (flat is approx. 15 years old), could anyone confirm this? Thanks!!!! (ps - no gas supplied to flat - all heating etc. is electric).
You can thank the Chinese for the price of metal on this one, a standard 36" x 18" cylinder can cost from Â£120 + Vat to around Â£180 + Vat that is almost double what it would have cost 2 years ago. The Immersion heater will also need replacing around the Â£20 mark as the existing one is not up to code. Depending on quality of tank 15 to 20 years life span is a fair estimate. What you have to figure is around Â£600 for around half a days labour reasonable and is the price including or plus VAT? I have not seen the job but it seems a lot to change a cylinder but there may be reasons for this i.e. he will need to employ an electrcian to wire the immersion heater and perform a full wiring check to meet part P requirements. Make sure this is included, if it is then it becomes more of a resonable price. Do not pay any money up front wait to pay once the job is complete and you have the part P documentation.
Part P refers to the current building regulations if in doubt what this is about do a internet search or contact your local building officer at the council.
