Are Zerohomebills still trading?

Everytime I have worked out how much stuff saves, even back in the FIT days its always been around 7 years. It seems to be a magic number.

Yes, it was the same for my original PV, cost £14,000 in 2011 (!) but paid back in 7 years and of course is now the gift that keeps on giving.

Much the the same here except poor orientation stretched it out to 10 years, it looks like the battery may pay back in nearer five years.

When I fitted our batteries I thought the payback was going to be a bit marginal, probably around 8 or 9 years. Now that the cost of electricity has shot up the payback time has reduced dramatically, probably to around 5 years. If the price of electricity continues to rise then that payback time may well reduce still further. I must admit I do feel a bit smug at being able to keep our (all electric) house at a fairly toasty temperature this winter, and charge the car, for our current direct debit of £12/month (although that's largely thanks to the £66/month government assistance).
