About CELLMARK SERVICES LTD
Company type and jurisdiction
CELLMARK SERVICES 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 00694901 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 65 years and 5 months.
What CELLMARK SERVICES LTD does
On the public register, CELLMARK SERVICES LTD lists its activity using the UK Standard Industrial Classification (SIC 2007): non-specialised wholesale trade (46900). This places it in the wholesale and retail trade and the repair of motor vehicles 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 CELLMARK SERVICES LTD is registered
Its registered office is in Slough (postcode district SL1). 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.
