John Lewis Insurance use CET for their home emergency service and they subsequently subcontract to other contractors, in our case SURE maintenance services. We have had maintenance engineers out six times and we have been without hot water and heating for over two weeks in the run up to Christmas. CET are absolutely appalling and totally unprofessional in dealing with any queries regarding our ongoing boiler repair. As an example I was kept on hold for twenty four minutes when trying to chase up the engineers to revisit us. If you have a choice please avoid the John Lewis Home emergency service as it is not worth the paper it is written on.
