About AJ SIMPSON ENGINEERING LIMITED
Company type and jurisdiction
AJ SIMPSON ENGINEERING LIMITED 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 SC522975 shows it was registered in Scotland, so its records are kept by Companies House in Edinburgh. It has been on the register for 10 years and 10 months.
What AJ SIMPSON ENGINEERING LIMITED does
On the public register, AJ SIMPSON ENGINEERING LIMITED lists its activity using the UK Standard Industrial Classification (SIC 2007): engineering design activities for industrial process and production (71121). 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 AJ SIMPSON ENGINEERING LIMITED is registered
Its registered office is in Ayrshire (postcode district KA21). 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
AJ SIMPSON ENGINEERING LIMITED must file its next annual accounts by 30 September 2027. 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 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.
