Use of minutes on company provided landline

[AndyNetwork]

OK, quick question for those in the know.

I have a land line which is provided by my employer for business use - They provide unlimited broadband on that line and also pay an extra fixed amount for unlimited national and mobile calls.

Would I be liable for tax as a benefit in kind if I use the broadband for personal use, and also use the phone, as on the bill the cost is identified as zero.

The bill is in the name of my employer if that makes any difference.

Thanks in advance

Bumping this, as I am still looking for some guidance.

Perhaps now it isn't between xmas and new year, then there is someone who can lend me some advice.

Cheers,

Andy
