Thank you for your review, we’re sorry to hear about your experience. Our customer care team have fully investigated this, your boiler was deemed Beyond Economical Repair due to the cost of the repair and the amount of parts required. This decision isn't made by the engineer; it was declared Beyond Economical Repair after the engineer had visited due to the amount of parts required to fix it. We sincerely apologise that this information was not provided to you at the time and feedback has been passed onto the relevant department. We apologise for any inconvenience caused with this.
