Thanks for the replies all!
My perspective is that any VAT registered supplier should provide a VAT invoice upon request. Furthermore it costs no more to generate a PDF featuring VAT than it does one that doesn't feature VAT.
I also don't believe that PlusNet are correct in putting 'business use only' in their T&Cs, it's a restrictive trading practice, it's not their business what the customer uses the connection for (unless it's illegal) and a large proportion all BB customers will use their connection for business use and either their employer or they themselves maybe VAT registered.
However if the business products were competitively priced and well featured it would not be a problem. Though a business product offers no advantages over a residential product, it will cost me more extra than I can reclaim in VAT and does not feature the entertainment packages.
They either need to offer VAT invoices on residential products or entertainment packages on competitively priced business products.
There's also a loyalty issue here, I've been loyal for nearly 15 years, when I signed up they just did broadband and provided VAT invoices as required.
