What happens if NB Energy Hero 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 21 April 2027.

| 3 to 6 months late | 22 Jul 2027 to 21 Oct 2027 | £750 |
| More than 6 months late | From 22 Oct 2027 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Aug 2027 | £200 |
| 3 months late | 31 Oct 2027 | another £200 |
| 6 months late | 31 Jan 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.
