I know of one friend who had a Wren kitchen fitted very much with a view to updating the existing kitchen to sell the property. That was during one of their sale/special offer periods, she seemed fairly satisfied with the outlay, she very much had an eye to updating on a budget. She didn't live with the kitchen for very long, as that measure shifted the house very quickly back when there was last an upsurge in the property market.
We went scouting for a new kitchen in our last house, visited a Wren showroom, we thought they were very expensive. Eventually used a small local firm who, were far superior imo and undercut Wren's prices. We were also interested in using Howdens as the feedback surrounding their kitchens is very positive. Two houses ago we had a Magnet and Southern kitchen fitted, but that was over 30 years ago, recently they again seem to have become rather more expensive.
