How Much Can You Claim for Use of Home?
May 22, 2011 | in Book Keeping, Featured by admin | 35 Comments »
Today we have another fantastically helpful post from Ruth addressing a question that is pertinent to all home workers whether you’re an indpendent baker or not. I’m going to work my way through the ‘difficult answer’ and I’ll let you all know how much of a difference it makes to my tax bill
Over to Ruth:
Hello again! BEWARE – This could be the most complicated blog post you’ll ever read!
This post is based on a forum question How much can I claim for Use of Home? There is an easy answer to this of course…and a more difficult one (well it IS to do with tax!). Which answer you need depends on how much you use your home, for most bakers you’re going to spend more than £3 per week by the time you’ve factored in electricity/gas for the use of the oven, hot water for washing up, heating etc., electricity for the running of the fridge, etc etc etc!
Easy answer
HMRC (that’s the tax man to you and me) will allow you to claim £3 per week for your use of home. They will allow this without any questions, you will never have to explain how you came up with this figure, it’s just fine by them. So, that £3 per week that you have been self-employed, £156 per whole tax year.
Difficult Answer (examples in bold)
The more difficult answer is obviously not as straight-forward. If you want to claim more than £3 per week, you can, but it must be backed up by how you got to the figure in case HMRC want to know. I’ll try and explain it easily.
- You need to count the numbers of rooms in your house, excluding hallways and landings (unless the landing or hallway also doubles up as an office for example). 6
- You then need to count how many rooms are used for the business, so for example it could be one – just the kitchen, or it could be three – the kitchen for cooking, the dining room table for modelling/piping buttercream etc and the living room, where the computer lives in the corner. 1
- You then need to work out, on average, how many hours a week those rooms are used for business (c1) 34 and how many hours a week they are used in total including business hours (c2) 42 (by the whole household not just be you).
- You then need to get together all your bills for the household including gas, electric, oil, water, cleaning (if you are lucky to have a cleaner – I’m not *sob*), rent, mortgage (interest amount only), council tax, insurance. I’ll come to telephone and broadband a little later.
So, I bet you’re thinking – ok, that bit’s not so bad – well, unfortunately this is where it starts to get a little more complicated :0
Now you have to decide which of your bills are Variable and which of them are Fixed, here’s a little table to help
| Bill | Type |
| Electric, Gas, Oil, Water | Variable |
| Council Tax | Fixed |
| Mortgage Interest | Fixed |
| Insurance | Fixed |
Now, you’ve done that – you can actually start to do some calculations – woohoo! So, first calculate your Fixed Cost multiplier (e) by taking the amount of business hours a week (c1) and dividing by the total number of hours in a week (24 hours per day x 7 days per week).
So if you use the rooms for business for a total of 34 hours per week, your Fixed Cost multiplier would be 34 ÷ (24*7) = 0.2024.
Next, calculate your Variable Cost multiplier (f) by taking the number of business hours a week (c1) and dividing by the total number of hours used per week (c2). 34/42=0.8095
Ok, so now you know
(a) Number of rooms in house 6
(b) Number of rooms used for business 1
(c1) Business Hours per week 34
(c2) Total Hours per week 42
(d) Cost of bills split into Variable and Fixed Variable £1750 Fixed £4675
(e) Fixed Cost multiplier 0.2024
(f) Variable Cost multiplier 0.8095
The next step is to work out your bills in yearly terms (or however long you’ve been trading for if less than a year). To do this you simply take a weekly bill and times it by 52 or take a four-weekly bill and times it by 13 or take a monthly bill and times it by 12 or take a quarterly bill and times it by 4 *phew*. Now add all your Variable bills (g) together and all your Fixed bills together (h). So now you should have all the above information (a) to (f) and also your Variable Annual bills (g) and your Fixed Annual bills (h).
Now we can actually calculate the Use of Home figure – at last I hear you cry!
Variable bills
Take your Variable Annual bills (g) and divide it by the number of rooms in the house (a)
£1750/6 = 291.67 then multiply it by the number of rooms used for business 1
= 291.67 x 1 = 291.67 (i)
Then you take this figure (i) and times it by your Variable Cost multiplier (f), this is the figure for Use of Home for Variable bills.
291.67 x 0.8095 = £236.11
Fixed bills
Take your Fixed Annual bills (h) and divide it by the number of rooms in the house (a)
£4675/6 = 779.17 then multiply it by the number of rooms used for business 1
= 779.17 x 1 = 779.17 (j)
Then you take this figure (j) and times it by your Fixed Cost multiplier (e), this is the figure for Use of Home for Variable bills.
779.17 x 0.2024 = £157.70
Telephone and Broadband costs
Telephone and broadband costs are dealt with in another way, you simply estimate the percentage of use used for business and then multiply the annual bills by that percentage.
75% of my broadband is business use, the annual cost is £235 so my Use of Home amount for business is 235 x 0.75 = £176.25
Now you add all the use of home figures up to calculate the total that can be put through your accounts, it is classed as Capital that you have invested into the business. If your bills are not in your name but in your partners/parents name then you must still calculate as above but treat the figure as if it is an invoice from a supplier. This can then be put through your accounts as if you have paid off the invoice using your personal money and is then treated in the same way, Capital that you have invested into the business.
An Excel spreadsheet is available free from me by email request that allows you to enter the information and the calculations are performed for you. If this is too confusing or you don’t have the time, energy or enthusiasm (can’t blame you there) I also offer a Use of Home calculation service of a flat fee of £10, this can than of course be put through your accounts as a business expense and go against any tax you may have to pay.

I think I need a lie down! Thanks Ruth, I am going to print it off and try and work it all out

thank youfor your help..sat down and managed to do it all in under 2 hours in between washing and feeding my 2 year old. Brilliant…
adele said on May 23, 2011
Oh my! Thank you for writing all that out! I think i’ll go with £3 a week for now, makes my head spin! Or I could pass it on to hubby…!
ruth said on May 23, 2011
If you would like the free spreadsheet, just email me and I’ll send it straight to you – it takes most of the complicated bits out for you. You could be under claiming with the £3 per week depending on how much time you spend on your business.
Samantha Jones said on May 23, 2011
Goodness me … it’s a bit complicated … could you possibly send me the spreadsheet too? I can’t even have the fallback of cake … I’m a photographer!
Tracy Clarke said on January 5, 2012
Ruth, could you please email; me the free spreadsheet, I would be very grateful. Thanks
Paulina said on July 29, 2012
Hello,
Great post. A lot to think about. Could you email me a copy of the spreadsheet.
Thanks
Paulina
Sharon said on February 17, 2013
Hi Ruth,could I be cheeky and ask for the spreadsheet too? Please
kathryncake said on May 23, 2011
Don’t be put off, Adele. I know it looks confusing, but it does work. Just takes a bit to get your head round! But it will definitely be worth it as £3.00 a week is seriously underestimating what you should be claiming back.

OMG!!!!!
ruth said on May 23, 2011
Ha – it that a good OMG or a I’m completely confused OMG??
putnoecakes said on May 24, 2011
This is really helpful, thanks for all the detail. The problem I’m having at the moment is that I’ve done all my costings and worked out my pricing, but I’m only getting about half of my quotes accepted. The others say I’m too expensive. I’ve done comparisons against others in my area for instance there’s one lady making cakes who charges just £25 for a rich fruit cake 6″ square, I can’t compete with that it’s less than half of what I charge! Any advice would be gratefully received.

Hi there, we are planning a blog post on this topic soon but in the meantime if you post this in the forums I’m sure you will get lots of responses. Definately an emotive topic! Julie
Holly Cook said on May 25, 2011
Thanks Ruth, really useful information. I’m going to have to sit down and read through again with a highlighter!
Angel's Kitchen said on May 26, 2011
Oh my! Erm……. That’s brilliant – think I’ll bookmark and read later – please Ruth, could you email me the spreadsheet too? Xxx
ruth said on May 27, 2011
Hi, can you email me so I have your email address please ruth@businesshelpandsupport.co.uk
donnamakescakes said on June 24, 2011
Wow, have been meaning to get on here and reas this for a while now as I had seen the tweets regarding it, that is a lot to get your head around! But I definitley think it is going to be so worth the time needed to work it out, I can imagine this is going to be a massive chunk of my bills. My gas/electric payment has gone up £30 a month since last year, nearly all if not all of that is down to running the business from home, my oven is never off! I would definitely like one of the spreadsheets, I will email you now x
Rhu Strand said on January 4, 2012
Just getting round to using your fantastic spreadsheet Ruth, thank you (downloaded a free trial of excel to use it as well) anyway…. after putting all my calculations in my allowances are coming pretty high …. do you think there is a ceiling to the amount you can claim? I do this full-time and from very early morning to late evening often 6 days a week, so it would come out high anyway !!!!
Your thoughts would be appreciated
ruth said on January 4, 2012
It’s a very valid question. There isn’t really a ceiling to the amount as obviously costs vary grately due to your particular circumstances.
HMRC do say that you should only claim a “reasonable” amount though so if the figures have come out quite high and you think it’s too much, put your claim in for less.
You also have to remember that what you think is high (or low) someone else may not, feel free to email me with the details and I’ll let you know what I think.
Sarah said on January 4, 2012
Wow and ong looks confusing but would be really grateful if you could email the spread sheet to me Ruth:-)
Might take me a while to get my head around it all though lol

I am very, very late to the party here but this is fantastic! Thanks so much Ruth, and thanks also to Julie for alerting me to this post. I can’t believe I missed it! I am just in the process of submitting last year’s accounts so the figure won’t be hugely different for then, I don’t think, but for this year…oh em gee is there a difference! Amazing! xx
