Galvanised water tank

[bluenun]

I am buying a 1968 built flat and had a survey done. Just read the report and 1 point noted was that there are Galvanised water tanks in the loft.

The surveyor recommended that the tanks are changed for plastic ones.
I can't get hold of the surveyer yet so thought I would ask here.

Is it a health issue why he recommends changing them or another reason?

If I change them, how much do new plastic tanks and associated fittings cost?

There is only a small loft hatch for access so I do not see how I would get the old tanks down and the new tanks up.

He is recommending replacement tanks most probably because of their age and therefore are likely to be corroded.

It is possible the original tanks were installed before the building was completed so there could be installation complications. You need to Google header tanks and do a little research about sizes and costs.
