Straight Flush (specifically Alec) has been servicing and looking after our central heating for nearly 10 years and he is always so knowledgeable, helpful and quick. When the heating stopped working they scheduled me in as quickly as possible and they alway manage to resolve it with the one visit. When I was trying to get more heat into our nursery, Alec gave me the most practical and simplest solution. He also points out other areas of risk and gives me a clear and practical solution. They are a great company and everyone I have dealt with are so helpful and trustworthy.
