Should a multi-trade builder use 43999 or a specific trade code?
If one trade brings in most of your income, use its own code. That means 43210 for electrical work or 43220 for plumbing and heating. Specific codes read better to insurers and merchants. Genuinely multi-skilled firms use 43999 or 43390, or list up to four codes covering their main trades. The choice is yours. Companies House records it without judgement, and you can change it on any confirmation statement.
