Owning rental property can be a rewarding investment—but the financial and tax obligations that come with it are anything but straightforward. Between calculating rental income, claiming allowable expenses, navigating HMRC rules, and filing self-assessment returns, the admin alone can consume hours that would be better spent growing your portfolio. That’s where specialist landlord accountants make a real difference. At Millbrook Accountancy Ltd, we work with rental property owners across England, providing expert financial guidance that keeps you compliant, tax-efficient, and in control of your finances. Based in London, our qualified team delivers a full range of landlord accounting services—accessible online, by phone, and by email—so help is always close at hand.
Whether you own a single buy-to-let or manage a growing property portfolio, this guide explains what landlord accountants do, why specialist advice matters, and what to look for when choosing the right firm.
What Do Landlord Accountants Actually Do?
Landlord accountants go well beyond general bookkeeping. They understand the specific rules that apply to property income, capital gains, and the ever-changing HMRC legislation that affects property owners in the UK.
Key services typically include:
- Self-assessment tax returns – Accurately reporting rental income and allowable expenses to HMRC
- Expense management – Identifying all legitimate deductions, from mortgage interest restrictions to maintenance costs
- Capital Gains Tax (CGT) advice – Calculating liability when selling a property and exploring available reliefs
- Stamp Duty Land Tax (SDLT) guidance – Ensuring you understand the surcharges applied to additional properties
- Corporation tax planning – For landlords who hold properties through a limited company
- VAT advice – Where applicable, particularly for commercial property or furnished holiday lets
At Millbrook Accountancy Ltd, all of these services are available to landlords across England, delivered through a streamlined online platform that removes the need for time-consuming in-person meetings.
Why Rental Property Owners Need a Specialist Accountant
General accountants handle a broad range of clients. Property accountants—those who focus specifically on landlords—bring a depth of knowledge that goes far deeper. The distinction matters because the tax rules around rental income are genuinely complex.
The Impact of Section 24
Since 2020, individual landlords can no longer deduct mortgage interest directly from rental income before calculating tax. Under Section 24 of the Finance Act 2015, landlords now receive a basic rate tax credit instead. For higher-rate taxpayers, this change significantly increases the effective tax burden on rental income.
A specialist landlord accountant can model the financial impact of this restriction on your portfolio and identify strategies to manage it—whether that’s restructuring ownership, reviewing allowable expenses more rigorously, or evaluating the benefits of incorporating.
The Limited Company Question
Many landlords are now exploring whether to hold properties within a limited company structure. There are genuine advantages—mortgage interest remains fully deductible for companies, and profits can be retained within the company at the corporation tax rate rather than personal income tax rates. However, incorporation carries its own costs and complexities.
Millbrook Accountancy Ltd advises landlords on exactly these decisions, helping you weigh the numbers before committing to a structure that could be costly to reverse.
What Allowable Expenses Can Landlords Claim?
One of the most valuable roles a landlord accountant plays is ensuring you claim every allowable expense available to you. Many property owners underestimate what qualifies as a deductible cost.
Allowable expenses typically include:
- Letting agent fees and management charges
- Maintenance and repairs (not improvements)
- Buildings and contents insurance
- Ground rent and service charges
- Accountancy fees
- Advertising costs for finding tenants
- Utility bills, where paid by the landlord
Capital improvements—like a new extension or a kitchen upgrade—are not deductible against income, but they can reduce a Capital Gains Tax liability when you come to sell. Knowing the difference, and documenting costs correctly, is where experienced landlord accountants add real financial value.

How to Choose the Right Landlord Accountant
Not every accountancy firm is equipped to handle the nuances of property taxation. When evaluating your options, look for:
- Demonstrated experience with rental property – Ask whether they regularly work with landlords and what services they offer specifically for property owners
- Knowledge of current legislation – Tax rules for landlords have changed significantly in recent years; your accountant should be up to date
- Transparent pricing – Avoid firms that are vague about fees; good accountants are upfront about costs
- Clear communication – You want an accountant who explains things clearly, not one who leaves you more confused than before
- Online accessibility – Modern landlord accountants should be reachable without requiring you to travel to an office
Millbrook Accountancy Ltd meets all of these criteria, with qualified accountants who understand both the commercial realities of property ownership and the regulatory environment landlords operate in.
Frequently Asked Questions
What is a landlord accountant and do I need one?
A landlord accountant is a qualified accountant who specialises in the tax and financial reporting needs of rental property owners. If you receive rental income in the UK, you are legally required to declare it to HMRC. A specialist accountant ensures your returns are accurate, your expenses are maximised, and your overall tax liability is minimised.
How much does a landlord accountant cost in the UK?
Fees vary by firm and the complexity of your tax situation. Millbrook Accountancy Ltd offers property and small business accounting from £70 per month—a competitive rate that includes access to qualified accountants via phone, email, and chat.
Can landlord accountants help with limited company property ownership?
Yes. Specialist landlord accountants, including the team at Millbrook Accountancy Ltd, advise on whether incorporating your property portfolio makes financial sense and manage all associated accounting and corporation tax obligations if you proceed.
What happens if I don’t declare rental income to HMRC?
Undeclared rental income is treated as tax evasion by HMRC and can result in significant financial penalties, back-tax payments with interest, and in serious cases, criminal prosecution. A landlord accountant ensures you meet all filing obligations on time.
Can Millbrook Accountancy Ltd help landlords outside of London?
Yes. While Millbrook Accountancy Ltd is registered in London, the firm operates a fully online service model and supports rental property owners across the whole of England.
Take Control of Your Rental Property Finances
Managing rental income without specialist support is a risk that costs landlords money every year—through missed expense claims, avoidable tax bills, and penalties for late or inaccurate returns. Working with experienced landlord accountants removes that risk and, in most cases, more than pays for itself.
Millbrook Accountancy Ltd provides expert landlord accounting services to property owners throughout England. Whether you’re a first-time landlord or managing a growing portfolio, our team is ready to help you stay compliant and financially efficient.
