Nathan the engineer and his assistant( I’m sorry I cannot remember the assistant name) that came around to install my boiler was very efficient helpful, knowledgable and friendly. They were on time the first day. They worked really hard to ensure I could have hot water and heating on the first day of installation. The second day they were back on time, to tidy up the pipe work. They did an immaculate job. Nathan and his assistant is a real asset to VHL and I will highly recommend the company and him to anyone that is looking for an engineer to install a boiler. Fay
