" I am very pleased with the service I received from Nassin of Vaillant Engineers Hammersmith & Fulham. I called up late at night for an emergency boiler repair and he arrived very promptly within the timeframe advised. He was polite, efficient at undertaking the work, very knowledgeable and above all honest, and he took the time to explain any questions I had around my heating system.
The fee was very reasonable and I will most certainly use this company again. I highly recommend. "
