Where SQUARE ROOT DYNAMICS LTD is registered

Its registered office is in London (postcode district EC2A). The registered office is the official address for letters from Companies House, HMRC and the courts.

Accounts and filing deadlines

SQUARE ROOT DYNAMICS LTD must file its next annual accounts by 6 February 2027. 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 19 May 2027. A private company that files its accounts late gets an automatic penalty of £150 if they are up to one month late, rising to £375, £750 and £1,500 after six months, and the penalty is doubled if accounts are late two years in a row. A company that does not file a confirmation statement can be struck off the register.
