you are probably paying extra for the 10m in addition to the 6.5, if you only think you need 7 it'd been worth dummying up a length of hose or something at the stock 6.5m to see if it would do first, assuming you haven't done that already, I should have done this
Yup grants are gone and other costs have gone up. Zappi unit is ~800, 10m cable about £150, never mind the additional bits that might be need from consumer unit. Hypervolt is cheaper.
