I have no idea how good Heritage sheds are because I did not get that far through the process of buying one.
When I began liaising with the sales representative (you will encounter her, there is only one) and described what we wanted, everything was going well. They even agreed to a custom fitting on our shed at a good price, marvelous.
Everything went down hill when we started to discuss painting the shed. 'If we buy the paint and paint it for you it will be £180' she said. Ok, we go away and think. The next time, we go into the shop to discuss the deal. We were told the painting would cost £247 this time round. I ignored this and we discussed instead some other details. The who experience by this point was starting to feel shaky. I did not feel at all my business was welcome.
We then go away and come back on a third occasion because our details were lost. Another order had to be arranged and the details had to be ironed out again. This time the painting would cost £300. At this point I knew for sure I was being taken the mick of and walked away feeling very ambivalent. Heritage have not contacted us since and threw away what could have been a very satisfactory arrangement. Bizarre.
