How we date a house

1. The domain registry

We ask the registry for the address through RDAP, the public lookup that replaced WHOIS. It returns the date of the current registration. If a name ever lapsed and was registered again, that date is later than the name's first life, which is why some houses have archived pages older than their registry date. ICANN's lookup tool shows the same records.

A registration date only says the address existed. It says nothing about what was on it: williamhill.com, for example, was registered in 1995, and the first copies the Web Archive holds from it belong to a winery.

2. The first archived gambling page

We list the copies the Internet Archive's Wayback Machine holds for each address, take the first working copy of every year, and read their page titles in order. The first title that reads as a gambling site (casino, betting, poker, bingo, slots and similar words) sets the date the house opened. We link that copy on every profile, so you can open it and judge for yourself.

The archive does not capture every site every day, so the real opening is often earlier than our date. We never move a date earlier on the strength of a press release or an "established in" line on the casino's own page.

3. The Gambling Commission register

The licence holder, account number, licence number and licence start date come from the register's downloadable files, downloaded on 3 November 2026. A house is included only if its address is listed under an account that holds an active remote casino licence. Regulatory actions come from each account's actions page.

The licence start date is the start of the licence the brand trades under today. Many read 1 November 2014, when the Gambling (Licensing and Advertising) Act 2014 required every operator serving Britain to hold a British licence; others reflect a later change of company.

Who makes the roll

• An active remote casino licence on the register, with the address listed under that account.
• At least 10 full years between the first archived gambling page and 3 November 2026.
• The same brand name over that time.

Years open measure staying power, nothing more. They do not rate games, payments or service, and an older house is not a safer place to gamble.

What we leave out

We do not publish offers, ratings or reviews, and no casino has asked to be listed or to be left out. If a date here is wrong, write to contact@seasonedhouses.co.uk with the record that shows it and we will correct the page.
