About ISOLER LTD.

Company type and jurisdiction

ISOLER 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 02766783 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 33 years and 11 months.

What ISOLER LTD. does

On the public register, ISOLER LTD. lists its activity using the UK Standard Industrial Classification (SIC 2007): other specialised construction activities n.e.c. (43999). This places it in the construction 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 ISOLER LTD. is registered

Its registered office is in Durham (postcode district DH1). 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

ISOLER LTD. must file its next annual accounts by 31 December 2026. The last accounts on the register were full audited accounts, usually filed by larger companies. Its next confirmation statement, which confirms its officers, shareholders and registered office are up to date, is due by 7 December 2026. 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

ISOLER LTD. has 6 charges registered against it, of which 2 are 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. The full charge documents can be read for free on Companies House.
