I was due a service and had a fault the day before. We managed to sort the fault but it came back the day of the service. The engineer said he had sorted it but when he went it wasn’t. I called them back and the day after an engineer said we had a blocked soil pipe which caused a blockage in the condensate trap. This should have been picked up with the service as part of the service is to check and clean that trap. Complained, charged nothing done, thjey deny it was in the service to clean that trap even though it’s in there service check list to do. Avoid them as I’ve had nothing but problems with this company
