Whoops! You are meant to register before you hit the threshold. ie if you are doing 10K a month you should have applied at around month 8.
If I was you I would first speak to HMRC and explain the situation and then get an accountant to file your application and paperwork. They will advise the best options and tell you how to keep your paperwork 'straight'..
You can not charge VAT until the date issued on your certificate. However you can claim VAT back on your assets for up to 6 months previous (or along them lines, it's been a long time). However your Certificate maybe back dated so you may be charging VAT before your certificate is issued. Job for the accountant to advise again.
Once registered you buy from whatever supplier is cheapest. However as most suppliers will charge VAT you ignore this amount (although you pay it initially you claim it back via your quarterly return). So if VAT registered Joe bloggs sells you an item for £100 + VAT (£117.50) or another seller who is not VAT registered sells you the same item for £110. You are obviously better buying from Joe Bloggs.
