Can you recommend any packages here? I'm considering VAT registration too. I think for the sake for ~£1K/year that can be expensed, having an accountant deal with it and advise here is a no-brainer in terms of time saving and having it done right.
I'd still recommend getting an accountant at least during the first year just so you can learn everything and have an authoritative resource for tax-related questions; you can drop them when you feel confident doing it all yourself.
