I thought I would leave a review here given I’ve been ignored for years by Wren including a formal written complaint. I will spare the detail and simply say - if using their fitting service, Wren do not need to validate the contractor and you have to be the person who checks that the contractor is certified, qualified and competent to install your kitchen and it’s not Wrens responsibility despite taking a fee for this. This resulted in my kitchen being wired incorrectly, the oven then not working and me having to pay another electrician to correct it. Response from Wren is that it’s my problem and not theirs and I should have checked. I expect the response may be “we always check our contractors” however mine wasn’t fitted correctly and I’ve now been ignored and am out of pocket.
