Do not use this business, they will not do the job properly, they will then tell you they don't care on the phone, when you send them proof, they will not answer any emails or telephone calls, they will also not provide you with a VAT receipt or for that matter they will not provide you with a receipt at all. I wonder how the tax office feel about that. When you call the number provided it is an international ring tone, so they are not UK based, even though they have registered a UK phone number. Dodgy business as per the above experience is an understatement !
