Letting them add CH or sealed system components seems to push the
price
way up. Even without that clobber it's still =A31K inc VAT which is
probably a lot more than the buy price of a megaflo, but practically

zero cost/hassle in the long term, unlike the unvented.

This price was ex-vat for the cylindrical version. I did specify a 3
way diverter with it, but still seems high.
