What happens if Energenix Engineering 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 11 November 2026.
| Companies House | Accounts delivered | Penalty |
|---|---|---|
| Up to 1 month late | 12 Nov 2026 to 11 Dec 2026 | £150 |

| 3 to 6 months late | 12 Feb 2027 to 11 May 2027 | £750 |
| More than 6 months late | From 12 May 2027 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Dec 2026 | £200 |
| 3 months late | 28 Feb 2027 | another £200 |
| 6 months late | 30 May 2027 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 30 Nov 2027 | another 10% of any unpaid tax |
For returns filed on or after 1 April 2026. Late three times in a row and the £200 penalties become £1,000 each.

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.
