Remote Work Electricity and Heating Cost

The Hidden Cost of Working From Home

Remote workers pay for their own office heating, cooling, electricity, and internet — costs that office employees never see. While employers sometimes offer home office allowances, many remote workers absorb these costs without calculating their true annual impact.

What You Can Claim Back

In many jurisdictions, self-employed remote workers can deduct a proportion of home energy costs as a business expense, based on the percentage of the home used for work and the hours worked. This calculator estimates both your true cost and potential deductible amount.

Why the Numbers Often Surprise People

Many people find that the extra energy cost of working from home is higher than they initially expected. Heating a room for eight hours a day, five days a week adds up quietly in the background. It can help to think of it as running a small office — because that is essentially what you are doing. Even modest daily costs become significant when multiplied across a full working year. This is worth noting when weighing up the real financial picture of remote or freelance work.

A Few Things People Often Overlook

One approach is to look beyond just electricity. Heating costs — particularly gas or oil — are easy to forget when estimating home office expenses. The number of rooms in your home matters too, since it helps estimate what proportion of your energy use is genuinely work-related. Many people also overlook seasonal variation, where winter months can significantly skew annual figures upward.

Quick example

With current monthly energy bill of 150 and daily work hours at home of 8 (plus total rooms in home of 5 and work days per month of 22), the result is 132.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
