Out of Scope Supplies, can register for VAT ?

Hi, I have a company based in the UK. The turnover is below UK VAT threshold. The company provides service to clients located in Hong Kong only. So, my turnover is derived entirely from supplying services business to business overseas. I think this would be outside the scope of UK VAT because of place of supply rules, Please correct me, if I'm wrong. Please advice whether or not I need to register for VAT or can i voluntarily register for VAT?

Hi Oujiseiyaku,
If you are a UK established business and only supply services where the place of supply is outside the UK, then you may voluntary register if those supplies would be taxable if supplied within the UK and you are incurring vat on purchases in the UK.
Please refer to notice 700/1 section 2.9
2. Basic principles 2.1 VAT — an introduction
For guidance on place of supply of services please refer to notice 741a 
Thank you.
