Ok thanks. I have 11 spots but am happy to buy a pack of 10. Again, the problem is I don't want to spend a lot of money as I am selling the property so won't get the full benefit of the cost saving in the long run. It is just for showing good energy efficiency for my Energy Performance Certificate that I need to produce for the sale.
Fantastic, thank you so much, that's very helpful. I appreciate that you came back to me even though I had already rated you.
