About Us

My name is Andy Dye and I am the owner and manager of ASD Heating. We started our Gas Safe Registered family business in the Hemel Hempstead area aiming to meet the needs of the local community.

Our aim is to provide a high quality, efficient, personable service that meets all of our customers` individual requirements.

I offer a full range of services, from minor repairs or moving a radiator to full heating installations, and everything in between

I hold public liability and indemnity insurance for £2,000,000, although I`ve never had to use it and I work carefully to make sure I don`t have to

We acredit our apprentices through the national government apprenticeship schemes.
