What happens if SG Electrical Installations Ltd files late
Companies House charges an automatic penalty the day after the deadline, and it rises the longer the accounts are late. These are the dates for this company's accounts due on 31 January 2028.

| 1 day late | 1 May 2028 | £200 |
| 3 months late | 30 Jul 2028 | another £200 |
| 6 months late | 30 Oct 2028 | HMRC estimates the tax and adds 10% of the unpaid tax |

Filing notes for electrical contractors
Electrical contracting companies are often a director plus a van and tools. Most fall within the micro-entity rules, so the accounts filed at Companies House are short, and the CT600 carries the tax detail.
