More insurance brokers and financial advisers are working from home now than ever before. Some have ditched the city office entirely. Others split their time between a home setup and client meetings. Whatever your arrangement, the tax position matters. HMRC allows you to claim legitimate home office expenses, but you need to understand what qualifies and what doesn't.
The difference between claiming what you're entitled to and over-reaching can be thousands of pounds. Worse, the difference between a reasonable claim and an aggressive one might trigger an enquiry. Neither outcome helps when you're trying to run a busy practice.
HMRC's Simplified Expenses Method: The Easy Option
If you don't want to track every penny, HMRC introduced a simplified scheme in 2013. You claim a flat rate based on hours worked from home.
The rates are simple:
- 25 to 50 hours per month: £10 per month
- 51 to 100 hours per month: £18 per month
- 101+ hours per month: £26 per month
For most brokers working full-time from home, that's £26 per month or £312 per year. This covers everything: rent, council tax, utilities, internet, phone line, even your desk and chair.
The beauty of this method is simplicity. You don't need receipts. You don't need to calculate a percentage of your mortgage interest or work out your property's business use fraction. You just declare the figure and move on. HMRC rarely questions it because the sums are modest.
But here's the catch. Many brokers with substantial home office arrangements can claim far more using the detailed method.
The Detailed Method: If Your Office Takes Up Real Space
If you have a dedicated room or a significant portion of your property used exclusively for work, you can claim actual expenses.
This is where brokers with a proper setup should consider going. Let's say you've converted a spare bedroom into an office. That room is 12 square metres. Your property is 120 square metres. Your home office represents 10% of your property's floor area.
You can claim 10% of:
- Mortgage interest (not capital repayment)
- Council tax
- Buildings insurance
- Utilities including electricity, gas and water
- Internet and phone bills
- General maintenance and repairs
For a detached house with a mortgage of £250,000 at 5% interest, that's roughly £12,500 per year in interest. Ten percent is £1,250. Add council tax at maybe £200 per year for the office space, utilities at £400, buildings insurance at £150, and internet at £150. You're looking at around £1,950 per year.
Renters can claim a proportion of their actual rent paid, though this is more complex with tax relief rules.
What About Equipment and Furniture?
This is where brokers often get confused. Office furniture and equipment follow different rules.
Items like desks, chairs, filing cabinets, monitors and lamps are generally classed as equipment. If the item costs under £500, you can write off the full cost against this year's profits. Buy a quality ergonomic chair for £400? That's a full deduction in the year you buy it.
More expensive items need capital allowances claimed across several years. But most brokers won't hit those thresholds unless they're furnishing a major setup.
Software subscriptions for your CRM, compliance tools or video conferencing platforms are fully deductible in the year you pay them. So are professional subscriptions and memberships.
Telephone, Internet and Utilities: The Tricky Bits
You can't claim 100% of your home phone bill or broadband contract unless your office has a separate line.
If you're using a standard home internet connection for both personal browsing and client calls, you need a reasonable split. Many brokers claim 50%. Some brokers working from home full-time claim 75% or more, and HMRC generally accepts this if you can justify it.
Mobile phones are trickier. If you use a business mobile exclusively for work, that's fully deductible. If it's a personal phone used for work calls, you're claiming a business proportion of a personal expense. This often won't pass scrutiny. It's better to keep a clear distinction.
Electricity and gas follow the same proportional logic as the flat rate method. If your office is 10% of your property, 10% of bills is reasonable.
Building Your Case with Records
If you're using the detailed method, keep evidence.
Obtain a survey or rough calculation of your property's total square footage and your office space. Photograph the dedicated office area. Keep your mortgage statements, council tax bills and utility invoices. Store equipment receipts and invoices for at least six years.
This isn't bureaucracy for its own sake. If HMRC enquires into your tax return, you'll have everything ready. For self-employed brokers, an enquiry usually focuses on income and claims that seem out of proportion. Clear records make the difference between a quick chat and a proper investigation.
When Professional Advice Makes Sense
Many financial services professionals are already comfortable with tax compliance through their day job. But home office expenses have specific rules that catch people out.
If your property is jointly owned with a spouse or partner, claiming home office expenses affects your capital gains tax position when you sell. If you're running a limited company as a broker, the rules differ from sole traders. If you've got a complex mortgage structure or rental income involved, the maths changes.
A conversation with an accountant costs £100 to £300 and can save you far more than that in mistakes or missed deductions.
The Bottom Line
You're entitled to claim the space and costs you use for work. HMRC recognises this. The simplified method works well for part-time home workers. The detailed method suits brokers with dedicated offices.
Choose one approach and stick with it. Don't switch between methods year on year. Track what you claim. Be honest about the percentage of your utilities and phone you're using for work.
If you're unsure whether something qualifies, ask. A brief conversation with your accountant or an HMRC helpline beats an awkward enquiry later.
