To whom it may concern,
This is to confirm that David Blakey Services Limited of Oxhey Village, Watford, Hertfordshire have serviced and maintained all the heating, ventilation and air conditioning equipment at both my offices at Nottingham Terrace, London NW1 and my private residence in Eaton Square, Belgravia, SW1 for the past 10 years.
The work has been conducted in a timely and efficient manner. I have found the staff to be polite and helpful at all times and I have no hesitation in recommending their services for such works to other parties.
