| 3 to 6 months late | 1 May 2027 to 31 Jul 2027 | £750 |
| More than 6 months late | From 1 Aug 2027 | £1,500 |
Penalties double if the accounts were also late the year before.

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.
