We bought a Wren kitchen earlier this year. It was a L shaped design. We wanted to keep our original granite worktop, but Wren said if this was the case we would have to employ our own fitter, which we did. Wren sent a man along to measure up. We made him aware that we were keeping our original work tops so all his measurments have to be relative to this. The units were delivered on time. When our fitter started to install then it soon became apparent that the Wren measurements were incorrect. Resulting in the corner unit too long and wide. When we asked Wren for someone to come and investigate, they refused. There excuse being that as we had used our own fitter they would not be responsible for an incorrect measurement by Wren. My advice for anyone buying a Wren kitchen DO NOT USE YOUR OWN FITTER. Regards Len. Wallbank
