Came to do a routine service and look at a small leak, turned out we needed a whole new boiler (old boiler, not cost effective to fix). Grant gave us clear guidance on what had happened and several quotes to replace the system, with a very clear / easy to use online quote system.He managed to get us booked back in quickly, and professionally and efficiently replacing the boiler, saving us the worry of a prolonged period with a broken boiler and no heating or hot water. There was a slight mishap but it was quickly rectified at Grants expense with no quibbling . Thank you
