Not sure how to sum up my experience with Regent5, so I am going to go out and just say that I am a big fan of this company and the chap who runs it Cham. I had a rather large project that had me fire two different contractors an overpriced lighting designer until I met Cham and his company. They came in and straightened out all the electrical and building automation chaos left over by my original low voltage and electrical contractors. If you’re building a large home and you require a technology and automation expert call this bloke and his company.
