Three addresses, all of them read by the same person. CrestCast is built and run by Luke Walsh BSc ACA PgDip, its founder and only developer, as a sole trader in Belfast, Northern Ireland. There is no company, so there is no company number and no registered office. More about who that is on the about page.

For publishers and editors
The calculators are free to use, need no account and ask for no email address. They are open for anyone to link to, and if one of them gives an answer you disagree with, hello@crestcast.co.uk reaches the person who wrote the maths.
How the forecast itself is calculated is documented on how the forecast works, and what CrestCast does and does not do is on the about page.
