About SIPHER LTD
Company type and jurisdiction
SIPHER LTD is a private company limited by shares. 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 17453520 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 2 months.
What SIPHER LTD does
On the public register, SIPHER LTD lists 3 activities using the UK Standard Industrial Classification (SIC 2007): business and domestic software development (62012); information technology consultancy activities (62020); data processing, hosting and related activities (63110). 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. See other companies with the same SIC code.
Where SIPHER LTD is registered
Its registered office is in London (postcode district W1W). The registered office is the official address for letters from Companies House, HMRC and the courts. It must be in the same UK jurisdiction where the company was registered, but it does not have to be where the business trades: many companies use their accountant's or a formation agent's address.

Accounts and filing deadlines
SIPHER LTD must file its next annual accounts by 11 June 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 24 September 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.
