Where KEYSTONE DEV STUDIO LTD is registered

Its registered office is in London (postcode district SE16). The registered office is the official address for letters from Companies House, HMRC and the courts.

Accounts and filing deadlines

KEYSTONE DEV STUDIO LTD must file its next annual accounts by 18 May 2028. So far no accounts have been filed yet, which is normal for a company less than about 21 months old. Its next confirmation statement, which confirms its officers, shareholders and registered office are up to date, is due by 31 August 2027.

A company that does not file a confirmation statement can be struck off the register.
