Submetering in a domestic property for business use - expenses?

    A quick question for anyone who runs a small business from home, or any tax experts come to that.


    I know that if you use a part of your home exclusively for business use, you can claim back a proportion of your bills against tax.

    I want to do the same, but rather than have a dedicated room as an office, all my 'business use' electricity is sub-metered. That is to say, my office is fed from the main consumer unit with a second consumer unit in the office. That consumer unit has another meter fitted, so I can record exactly how much electricity I use, rather than say I'm using 1/6th of my house for business. The consumer unit in the office also feeds another CU out in a shed/workshop, so any power I use out there is also recorded.

    Now, my office is not a typical home office with just a 'pooter, monitor and printer. Oh no. If only it were that simple. Right now, I'm running five computers, seven monitors, a router and a huge rack of electronic gubbins. Unless the Mrs is cooking a dinner or using the electric shower, my office draws more power for five or six hours a day than the rest of the house uses in 24 hours. Hence the submetering, to measure the actual consumption.

    So, the lovely people at EON.Next sell me my domestic electricity, a significant proportion of which I use for business, but not enough to warrant having a second 'commercial' supply installed at the property.

    So I can work out how many units x the unit rate the business uses in a month, and pay myself back for the actual electricity used. Simple.

    So long as I keep accurate records (I do - daily readings on the main meter and the submeter) and keep track of my actual energy costs, are HMRC happy with that as far as expenses are concerned?

    Anyone else in a similar position? If so, how do you play it?

    It seems to be golf star level administration and unchallengeable. I doubt many businesses are as conscientious.

    Chatting with a fellow businessman today, he did actually tell me that there are two ways of dealing with expenses when running a business from home. The allowance for using one room exclusively for business, or totting up exact expenditure and claiming that. I told him I used the totting up method.

    When I explained I'd spent my afternoon and evening the other day, doing my accounts and my tax returns and had gone way over my usual quota for coffee consumption he asked me did I have to make it myself, or did the other half keep me supplied? I told him I just went out of the office and made a coffee in the kitchen, then took it back out and cracked on.

    "Oh no...." he said. "Take the kettle out to the office and boil it on company money!"

    if you set up a new company with a small amount and close it later with an undistributed surplus of 12500 I think you can take that as a capital gain.

    Handy information for someone self-employed working from home. My situation is a little different as I run a limited company, for which the expense situation is rather different!

    Anyway, HMRC seem happy enough for me to do it the way I do, with metering my business usage separately from domestic usage 👍
