What happens if Safe Isolation UK 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 14 April 2028.

| Up to 1 month late | 15 Apr 2028 to 14 May 2028 | £150 |

| 3 to 6 months late | 15 Jul 2028 to 14 Oct 2028 | £750 |
| More than 6 months late | From 15 Oct 2028 | £1,500 |
Penalties double if the accounts were also late the year before.
| HMRC (CT600) | From | Penalty |
|---|---|---|
| 1 day late | 1 Aug 2028 | £200 |
| 3 months late | 31 Oct 2028 | another £200 |
| 6 months late | 31 Jan 2029 | HMRC estimates the tax and adds 10% of the unpaid tax |
| 12 months late | 31 Jul 2029 | another 10% of any 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.
