Licensing and compliance costs
Per room reporting
An HMO accountant separates the costs that are deductible from the conversion spend that is capital, claims capital allowances on qualifying plant in communal areas, and reports profitability per room rather than per building.
Turning a house into an HMO usually mixes all three. Fire doors, alarm systems and emergency lighting may qualify as plant with capital allowances available in communal areas. Structural work is capital against a future gain. Redecoration is a repair. Splitting the builder's invoice correctly is worth real money.
Mandatory and additional licensing fees, fire risk assessments, gas and electrical certification, and periodic inspections are running costs of the business. Where a licence covers several years, the cost is spread over the period it relates to.
HMO returns depend on occupancy and on bills that the landlord usually pays. Reporting gross yield per room against void weeks and utility cost shows which rooms carry the property. That is also the evidence lenders want when you refinance.

“We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.”
“I am very satisfied with the service provided by Muhammad Saifullah. He has been handling my tax situation in the UK with great professionalism, clarity and attention to detail. He took the time to explain every step of the process and made a complex situation much easier to understand. I felt confident and well supported throughout.”
“I had a positive experience with Accotax. The work was completed promptly, my tax return was successfully filed, and I received a refund of overpaid tax. I found the cooperation efficient and helpful. Special thanks to Muhammad Saifullah for his assistance.”
Frequently asked
On qualifying plant in communal areas, generally yes. Items within a dwelling house are restricted.
Yes, spread over the period the licence covers.
HMOs are often held in companies because of the finance cost restriction, but it depends on your wider position.
The answer depends on financing, existing gains, income tax rates, extraction plans and long-term ownership. Moving an existing property can trigger tax and legal costs, so compare the full life-cycle position before changing ownership.
Repairs that restore an asset are commonly revenue costs, while improvements and acquisition costs are usually capital. The distinction affects current tax relief and the gain on a later sale, so invoices should describe the work clearly.
Keep bank statements, sales and platform reports, purchase invoices, payroll records, VAT workings, finance agreements and Companies House correspondence. We confirm the exact list at onboarding and identify gaps before a filing deadline becomes urgent.
The fee depends on transaction volume, record quality, VAT and payroll requirements, historic catch-up and the level of reporting needed. We agree a fixed scope and price before technical work starts, with published packages available on our fees page.
Yes. We request professional clearance, collect the prior records and authorities, check the next Companies House and HMRC deadlines, and give you one clear handover list. The process is normally completed remotely.
Yes. We work through secure cloud records, scheduled reviews and digital approvals, while keeping a named team available by phone, video call and email. Clients can also visit our Morden office by appointment.
We regularly work with Xero, QuickBooks, FreeAgent, Sage and connected sales or expense apps. The right setup depends on transaction volume, integrations and the reports you need, not simply the software brand.
