Pressure issue with heating system and leak on hot water tank After having 2 engineers fail to diagnose the issues with our pressure dropping, we called Andy and he identified the issue straight away. He explained to us what the issue was, as well as what he would need to do correct it. Once he carried out the work, everything is good and back to normal! Thanks Also, he managed to seal a persistent leak on our hot water tank. Very clean and tidy work, punchual timing.... Would highly recommend to anyone who's looking for a genuine honest company. Will definitely keep in mind for...
