I embarked on a very large renovation project of my house and garden, which has involved a large number of tradesmen.  Simon Cooper is one of the few that I would reemploy and recommend unreservedly to others.  
He is reliable.  
He gave me a target date to start the work then kept in touch to update me on his definitive start date, which he stuck to. 
He is a perfectionist and sees solutions, not problems
He has undertaken a variety of tasks, large and small and at the commencement of each, has asked intelligent questions to ensure he understood exactly what I wanted, often offering advice on improvements that could be made. 
He is a polite and friendly man with honesty and integrity and I had no reservations about leaving him a key to my home whilst I was out at work.
