About MAINFIX LTD

Company type and jurisdiction

MAINFIX 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 17469029 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 1 month.

What MAINFIX LTD does

On the public register, MAINFIX LTD lists 2 activities using the UK Standard Industrial Classification (SIC 2007): electrical installation (43210); plumbing, heat and air-conditioning installation (43220). 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 MAINFIX LTD is registered

Its registered office is in London (postcode district SE7). 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

MAINFIX LTD must file its next annual accounts by 19 June 2028. So far no accounts have been filed yet, which is normal for a company less than about 21 months old. Its next confirmation statement, which confirms its officers, shareholders and registered office are up to date, is due by 2 October 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.
