Internet - Working From Home

[Uzoma]

I work from home and I regularly use the internet.

There is no way to show how much internet usage is for personal use and how much is for business use (at least, not that I can think of).

Is there anyway to consider claiming this as a business expense?

You can only claim for internet usage if the element of business usage adds to the cost of your internet access.

So if, without the business use, you'd be using a service with a 10Gb per month cap but your business forces you to use a service with a 40Gb per month cap, you can claim the difference in price as an allowable expense.

However if you're using an uncapped service (which you'd be using anyway even without the business element) then, even if your business use is nearly 100% of the total, you can't claim anything because there's no additional cost to you:

Chris' information only applies if you are an employee of an employer, and you are asking if you can request reimbursement from your employer.
I suspect you are self-employed, and if so you need to be careful on two grounds.
One, you would be well-advised to do anything that might be construed as a business use of part of your home, or you could become liable for part-business use for rates.
Two, most broadband charge more for business packages.
You can claim a fixed amount from your business for expenses in another part of the allowed HMRC rules. It is not much (£2 per week, unless it has changed) and I'd be inclined to limit it at that.

Thanks guys.

I am an employee of an employer on unlimited broadband so I guess Chris is right.
