I had a replacement boiler installed, as my old one of 20+ years, covered by British Gas, had broken down. British Gas were unable to attend for 4 weeks (even to look at the problem!), despite me having a service contract with them! I could not wait that long for water and heating, so I telephoned VHL on the morning of the breakdown, and within 3 working days a new boiler was up and running. The whole experience with VHL was fast and efficient, and well priced too. The engineer was polite, friendly and did an excellent job, giving lots of useful advice, and leaving the area clean and tidy. Also, the engineer's assistant, and the original engineer who attended and quoted for the boiler, were also of the highest standard. The customer service personnel were polite and helpful, and the email system used to manage the booking was really useful. I have since decided to take out a service contract with VHL for all my heating and plumbing system, which was less than half the price that British Gas were charging me.
