Just FYI, when you do need to register for VAT make sure you check out the benefits of Flat VAT, for us it was significantly more economical then regular VAT registration. I'm constantly surprised how many accountants don't seem to even make their clients aware of this option.
Thanks for the advice. I was pretty close to the threshold last year and it's looking likely I'll have to register this year so I'll certainly look into it. I'm actually between accountants at the moment, although HMRC's own PAYE RTI app at least makes that side of things ridiculously easy for me. I certainly wasn't looking forward to dealing with VAT on my own.
I quickly discovered that quarterly VAT returns were a pain, and accountants aren't cheap (for some definition of cheap).
I am also just a one man band at the moment, and de-registered for VAT about a year ago. Unless there are significant savings to be made, or you're over the £82k per annum revenue threshold, factor in the cost of the effort to submit these returns. They really are just a distraction from the main focus of your startup business.
