A Home/Res service will have a VAT invoice too. However, HMRC and in and in advance of them, the accountant auditor, may well reject a Residential Service invoice addressed to Mr XXXX unless proof that it is only used for business can be provided and even then may still raise objections.
I have been involved with a few sole traders and small companies and in a couple of cases they have tried to claim their residential BB as an expense which has been rejected. The easiest solution was to migrate from BT Res to BT Business - slight increase in cost with no contract break fees though and everything was then fine.
