About TRIANGLE SECURITY LTD
Company type and jurisdiction
TRIANGLE SECURITY 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 03358775 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 29 years and 6 months.
What TRIANGLE SECURITY LTD does
On the public register, TRIANGLE SECURITY LTD lists its activity using the UK Standard Industrial Classification (SIC 2007): other service activities n.e.c. (96090). This places it in the other service 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 TRIANGLE SECURITY LTD is registered
Its registered office is in Ruislip (postcode district HA4). 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
TRIANGLE SECURITY LTD must file its next annual accounts by 31 March 2028. 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 6 May 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.
Charges and secured debt
TRIANGLE SECURITY LTD has 1 charge registered against it, of which 1 is still outstanding. A charge is security given to a lender, such as a mortgage over property or a debenture over all the company's assets; if the company does not repay, the lender can take those assets first.
