Common questions
Which register should a engineer be on?
In this market the registers we track that actually cover engineers are: Colorado DORA, Connecticut DCP. Which one applies can depend on where the work is and what exactly it involves, so check the register that covers your area and ask the contractor which registration they hold.
Does being listed mean they are good?
No. A register tells you someone is listed for the work, not how they treat customers. After the register check, look at the public evidence: reviews across sources and their dates, company status, and how their rating sits against the market's real distribution.
What do the entry counts mean?
The number is the public register entries we have found for this trade, as of 2026-07-16. It is not the register's own live total, and the official body's site is always the final word.
