About MAINSTACK GROUP LTD

Its owners (shareholders) are only liable for its debts up to the value of their shares, it must have at least one director, and its shares cannot be offered to the public. Its company number 17113405 shows it was registered in England and Wales, so its records are kept by Companies House in Cardiff. It has been on the register for 7 months.
What MAINSTACK GROUP LTD does
On the public register, MAINSTACK GROUP LTD lists its activity using the UK Standard Industrial Classification (SIC 2007): information technology consultancy activities (62020). This places it in the information and communication section of the economy. SIC codes describe what a company says it does; they are not a licence and are not checked by Companies House.

Accounts and filing deadlines
MAINSTACK GROUP LTD must file its next annual accounts by 24 December 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 15 May 2027.
