About SISAF LTD

Company type and jurisdiction

SISAF 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 05974331 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 20 years.

What SISAF LTD does

On the public register, SISAF LTD lists its activity using the UK Standard Industrial Classification (SIC 2007): research and experimental development on biotechnology (72110). 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 SISAF LTD is registered

Its registered office is in Guildford (postcode district GU2). 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.

A company that does not file a confirmation statement can be struck off the register.
