How much can you claim for using your home as an office as a limited company director?

HMRC provides a flat-rate allowance for individuals working from home. For the 2024/25 and 2025/26 tax years, you’re able to claim £6 per week without the need for providing receipts of justification for the amount. £6 per week totals £312 annually. This method provides a very straightforward way of claiming back your expenses when the amount you’re spending for your home office is minimal. 

If your home office space is substantial, you may decide to calculate the actual costs. This process involves apportioning your household expenses based on the space and time your business occupies. For example, if you used one room out of a total of five purely for business purposes, you may be able to claim 20% of your household expenses. Whilst this may sound appealing, it’s important to understand that this method requires detailed record keeping and receipts and that not all household expenses can be included within the calculation. For example, fixed costs can’t be included because HMRC argue that these would be incurred for your primary residence whether you worked from home or not. However, variable expenditure such as heat and electricity can be claimed.  

If you’re using a significant area of your home for business use, it could potentially affect your eligibility for Capital Gains Reliefs, such as Private Residence Relief. It’s essential to consider these potential implications before putting in any significant home office expense claims.
