About CST INSTRUMENTS LIMITED
Company type and jurisdiction
CST INSTRUMENTS LIMITED 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 08033783 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 14 years and 6 months.
What CST INSTRUMENTS LIMITED does
On the public register, CST INSTRUMENTS LIMITED lists its activity using the UK Standard Industrial Classification (SIC 2007): other research and experimental development on natural sciences and engineering (72190). 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 CST INSTRUMENTS LIMITED is registered
Its registered office is in Letchworth Garden City (postcode district SG6). 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
CST INSTRUMENTS LIMITED must file its next annual accounts by 31 January 2027. The last accounts on the register were micro-entity accounts: a very small company (turnover up to £1m, balance sheet up to £500,000, 10 or fewer employees) that files a simplified balance sheet. Its next confirmation statement, which confirms its officers, shareholders and registered office are up to date, is due by 25 February 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.
