Can My Limited Company Pay for My Home Office?

16 Jul Can My Limited Company Pay for My Home Office?

Since the shift toward remote and hybrid working, "How much of my home can I put through the business?" has become one of the most common questions we hear at Harrison’s Accountancy.

If you are a director of a limited company, the short answer is yes, your company can pay for your home office. However, as with most things involving HMRC, the "how" matters just as much as the "how much."

Whether you’ve just set up your company or you’ve been running a consulting business for years, understanding how to claim home office expenses can save you a significant amount of tax. Let’s break down the rules for 2026 and explore your best options.

Does your company need a home office?

Before you start claiming, you need to establish that working from home is a genuine requirement.

HMRC generally allows home office claims if you perform substantive duties of your employment at home. For most Limited Company directors, this is easy to prove, it’s where you do your admin, your calls, and your strategy.

There are three main ways to handle home office costs. Each has its own set of rules, pros, and cons.

Option 1: The HMRC Flat Rate (The stress-free route)

The easiest way to claim is via the HMRC flat-rate allowance for "use of home as office."

For the 2026 tax year, the company can pay you a flat rate (currently £6 per week) to cover the additional costs of working from home.

• How it works: Your company records an expense of £312 per year (£6 x 52 weeks). This reduces the company’s taxable profit, saving you Corporation Tax.
• The benefit: You don’t need to keep receipts or perform complex calculations. HMRC accepts this figure as a reasonable estimate of your "extra" costs, like the tiny bit of extra electricity or heating you use while working.
• The downside: It’s a very small amount. While it’s better than nothing, it rarely reflects the true cost of running a full-time home office.

Option 2: Claiming "Actual Costs"

If your home office costs are significantly higher than the flat rate, you can claim based on your actual bills.

However, this is only for the additional costs incurred because you are working from home. You can't simply put your whole mortgage or rent through the company.

• What you can claim: A proportion of your electricity, heating, and water bills.
• What you usually can't claim: Fixed costs that you would pay anyway, such as Council Tax, Rent, or Mortgage Interest. HMRC argues these costs are the same whether you work from home or not.
• The calculation: You need to calculate the number of rooms in your house and the percentage of time you use one for business. For example, if you have 5 rooms and use one as an office for 50% of the time, you could claim 1/10th of your energy bills.

Option 3: Setting up a Rental Agreement

This is the most "tax-efficient" but also the most complex method.

If you spend a lot of time working from home, you can personally "rent" a room to your limited company.

• The setup: You and your company enter into a formal license or rental agreement. The company pays you rent for the use of the space.
• The tax benefit: The rent is a 100% deductible expense for the company, reducing Corporation Tax.
• The catch: You must declare this rent as property income on your personal tax return. You can then offset a proportion of your actual home costs (including mortgage interest or rent) against that income.

A word of caution: The rent must be "commercial", meaning you can’t charge your company £5,000 a month for a box room. It should reflect market rates for a small office in your local area.

Can the company buy my desk and chair?

Yes, your limited company can buy the equipment you need to do your job.

If the company buys furniture or technology, it owns the asset. These items are usually 100% deductible for Corporation Tax under capital allowances.

• What’s covered? Desks, ergonomic chairs, bookshelves, laptops, monitors, printers, and even things like routers or shredders.
• The "Dual Use" Rule: HMRC is strict about items that have a significant private use. If you buy a top-of-the-range gaming PC and use it 90% for personal fun, the company shouldn't be paying the full bill. However, if the private use is "incidental" (like checking a personal email on a work laptop), it’s generally fine.
• Internet and Phone: If the contract is in the company's name, the company can pay the whole bill. If it’s in your name, you can only claim the business portion of the usage, which is notoriously difficult to calculate these days with unlimited data plans.

The Pitfalls: CGT and Business Rates

Be careful not to make your office "too exclusive."

While it’s tempting to claim that a room is used 100% for business, this can trigger some unintended consequences.

1. Capital Gains Tax (CGT): When you sell your main home, you usually don’t pay CGT (this is called Principal Private Residence relief). However, if a part of your home is used exclusively for business, you might lose that relief on that specific portion of the house.
2. Business Rates: If your home office is used exclusively for business and is visited by clients or modified significantly, the local council might try to charge you business rates instead of Council Tax.

Pro tip: To avoid these issues, most directors ensure their home office is "multi-purpose." Keeping a sofa-bed or a treadmill in the corner can be enough to show that the room isn't exclusively for business.

Which option is right for you?

There is no one-size-fits-all answer, but here is a quick guide:

• Choose the Flat Rate if: You want zero hassle and don't mind missing out on a few extra pounds of tax relief.
• Choose Actual Costs if: Your energy bills are high and you don't mind a little extra bookkeeping.
• Choose a Rental Agreement if: You have a dedicated office, high mortgage interest/rent, and want to maximize your tax savings (and you have an accountant to help you set it up).
