Bobbie Said:

has anyone in the UK had Everest solar heating fitted for hot water, if so how much did it cost?

We Answered:

They wanted to charge 2 X 4500 for my 4 bedroom terraced house.
If I had accepted I had to wait at least ten years to see any saving.
When I said no they continue to pester me for at least 2 months and dropped the price down to 2 X 2250.
the reason of the X2 is because they thought I needed two units.
