About CD3S LTD

Company type and jurisdiction

CD3S 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 16645698 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 1 year and 2 months.

What CD3S LTD does

On the public register, CD3S LTD lists 2 activities using the UK Standard Industrial Classification (SIC 2007): other engineering activities (71129); specialised design activities (74100). This places it in the professional, scientific and technical activities 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 CD3S LTD is registered

Its registered office is in London (postcode district EC1V). 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

CD3S LTD must file its next annual accounts by 12 May 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 25 August 2026 and is overdue. 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.
