   I cannot recommend Craig enough for his services, ranging from communication, time keeping, politeness and thinking outside of the box to resolve my central heating issues. I would have no hesitation calling Craig again. Thank you for your professionalism and skills! Marie

   Principal Heating replaced my boiler recently and the service they provided was exceptional, from coming along to quote a price for replacing the boiler which was in my loft so a difficult place to remove the old boiler and install the new one, they ensured that there was no mess or dirt in my house and that all the rubbish was collected. I would not hesitate in recommending them.
