Tax-Deductible Expenses Every Teesside Landlord Should Know About

One of the most common questions from Teesside landlords is straightforward: what can I actually claim? The answer matters. Many landlords managing one or two properties are paying more tax than they need to because they're not claiming all the expenses HMRC allows.

Understanding tax deductible expenses isn't about aggressive tax planning. It's about knowing the rules and making sure you're not leaving money on the table. HMRC allows landlords to deduct a wide range of costs from rental income before calculating the tax owed. Get this right, and you could reduce your tax bill by hundreds of pounds per year.

How Rental Income Tax Actually Works

Before looking at specific deductions, here's the structure. Rental income gets added to your other income and taxed at your marginal rate: 20% for basic rate taxpayers, 40% for higher rate, 45% for additional rate.

But here's the key: you only pay tax on your profit, not your gross rental income. Profit is calculated as your rental income minus your allowable expenses. The more legitimate expenses you claim, the lower your taxable profit, and the less tax you owe.

Let's make this concrete. A Middlesbrough landlord earning £7,200 per year in rent from a single property, who claims £3,000 in allowable expenses, reduces the taxable amount to £4,200. For a basic rate taxpayer, that's a tax saving of £600 per year. That's real money—£600 that can go straight back into maintaining or improving the property, or into your pocket.

This is why many landlords find it worth paying for professional accountancy. A decent accountant costs £150–£300 per year and often pays for itself ten times over by identifying deductions you'd miss.

Letting Agent Fees

If you use a letting agent to manage your property—and for most Middlesbrough landlords, that's the cost-effective choice—the management fees are fully deductible. This includes the monthly management percentage, tenant-find fees, and charges for inventory checks, property inspections, or reference checking.

There's no upper limit on agent fees. The cost is deductible regardless of whether you pay 8% or 15%. At Ascot Knight's rate of 8% management on a typical Teesside property renting at £650–£850 per month, this could represent £480–£640 per year in deductible costs. For a higher-rent property in TS1, that figure could easily reach £1,000+.

If you move properties between agents, or stop using an agent mid-year, the fees paid are still deductible. Only the portion of the year the agent was active is relevant.

Repairs, Maintenance, and Furnishings

This is often the largest category of allowable expenses for Teesside landlords. Plumbing repairs, electrical work, roof repairs, repainting, replacing broken fixtures, damp treatment—all deductible. If something is broken and you fix it, that cost is allowable.

HMRC makes one crucial distinction: repairs vs. improvements. Replacing a broken boiler with a like-for-like equivalent is a repair (fully deductible). Upgrading from a standard boiler to a premium system with additional features could be classed as an improvement (not deductible). Replacing broken double-glazed windows with new double-glazed windows is a repair. Installing double glazing where single glazing existed is an improvement.

For Teesside properties—many of which are Victorian or Edwardian terraces—maintenance costs can be substantial. Properties built before 1970 often have unexpected costs: pointing, render repairs, slate replacements, chimney works. Claiming these properly makes a real difference. The golden rule: if you're restoring something to its original condition, it's a repair. If you're upgrading beyond that, it could be an improvement.

Since April 2016, you can also claim the cost of replacing furnishings in a rental property. This applies to furniture, appliances, kitchenware, and soft furnishings—but only when replacing an existing item, not furnishing a property for the first time. If you replace a washing machine, cooker, fridge, sofa, or bed, the replacement cost is deductible. If you upgrade—say, replacing a standard fridge with an American-style model—you can only deduct what an equivalent replacement would have cost.

Insurance and Compliance Costs

Landlord insurance premiums are fully deductible. This includes buildings insurance, landlord liability, rent guarantee insurance, and contents insurance if the property is furnished.

A typical Middlesbrough property costs between £150–£350 per year, depending on the property type, location (TS1, TS3, TS5, TS7), and level of cover. If you have multiple properties, some insurers offer multi-property discounts, but each policy's full cost is still deductible.

All mandatory safety compliance costs are also deductible: your annual Gas Safety Certificate (CP12), your five-yearly Electrical Installation Condition Report (EICR), any remedial electrical work to meet standards, Legionella risk assessments (required if the property has a water storage tank), and Energy Performance Certificate (EPC) costs.

For a Middlesbrough landlord, these typically add up to £200–£400 per year when averaged across inspection cycles. Gas Safety checks cost around £40–£60; EICR around £150–£250; EPC around £60–£120. These are all allowable.

Mortgage Interest, Other Deductions, and Professional Fees

Mortgage interest: This is widely misunderstood and has cost many landlords thousands. Since April 2020, landlords can no longer deduct mortgage interest directly from rental income. Instead, you receive a tax credit worth 20% of your mortgage interest payments.

For basic rate taxpayers, the effect is broadly the same as the old system. For higher rate taxpayers (40%), this change significantly increased the effective tax on rental income. If you're a 40% taxpayer with substantial mortgage interest, you're effectively taxed on income that's going entirely to service debt. This is one significant reason many higher-rate landlords have moved properties into limited companies, where mortgage interest remains fully deductible.

Whether a company structure is right for you depends on your tax rate, mortgage structure, and portfolio scale. It's absolutely worth discussing with a specialist property accountant—the wrong structure costs thousands over time.

Accountancy and legal fees: The portion of accountancy fees related to your rental income is deductible. If you use an accountant for other work too, you can only claim the rental proportion. Legal fees for renewing tenancy agreements, preparing new tenancies, or dealing with tenant disputes are allowable. Legal costs for buying or selling the property itself are not deductible against rental income, though they may be relevant for Capital Gains Tax calculations.

Utilities and council tax during void periods: When your property is empty between tenancies, you remain responsible for council tax and utility bills. These are deductible expenses. This is particularly relevant if you're carrying out refurbishment or maintenance work between tenants. Council tax and utility costs during that period can all be claimed.

Middlesbrough Council may offer a council tax discount for empty properties for a limited period, but any amount you do pay is still an allowable expense.

Travel costs: If you travel to your Middlesbrough rental property for management purposes—inspections, meetings with contractors, handling tenant issues—those costs are deductible. HMRC's approved mileage rate is 45p per mile for the first 10,000 miles, or 25p per mile thereafter. Alternatively, you can claim actual fuel costs, parking, and tolls if you keep receipts.

For landlords living outside Teesside, this can be a meaningful deduction, particularly if you make regular visits to oversee the property.

Keeping Records and Getting Professional Advice

HMRC requires you to keep records of all rental income and expenses for at least five years after the relevant tax year. Keep receipts, invoices, bank statements, and a clear log of any property travel. Good record-keeping is not just about compliance—it's about defending yourself if HMRC questions a claim. (They will.)

If a receipt is missing, note what it was for, when, and why. A contemporaneous written record is often acceptable even without the original receipt. What HMRC wants to see is a clear trail showing that the expense was wholly and exclusively for letting purposes.

The tax rules change frequently, and individual circumstances vary. What we've outlined here covers the main categories, but there may be additional allowances depending on your situation—particularly if you own multiple properties, are considering incorporation, or are planning significant refurbishment work.

Frequently Asked Questions

Q: Can I claim council tax on my rental property? A: Only if the property is empty between tenancies. Once a tenant moves in, they're responsible for council tax. You can't claim it as an expense.

Q: Is mortgage capital repayment deductible? A: No. Only mortgage interest receives tax relief (as a 20% credit). Capital repayment—the principal you're paying down—is not deductible. This matters: on a typical Middlesbrough buy-to-let mortgage, you might pay £300 in interest and £200 in capital each month. Only the £300 is relevant to tax.

Q: Can I claim home office costs if I manage the property from home? A: Yes. You can claim a proportion of home office costs (rent, council tax, utilities, broadband, phone) proportionate to the space used for property management. Keep records documenting the time and space dedicated—for example, "30% of spare bedroom used 10 hours per week for letting management."

Q: If I replace a boiler because it's broken, is that always deductible? A: Yes—replacing a broken boiler with a like-for-like equivalent is a repair and fully deductible. Upgrading to a premium model with enhanced features (WiFi control, smart zones) may be treated as an improvement and disallowed.

Q: Am I allowed to claim for work I do myself on the property? A: No. You can't claim a wage or labour cost for your own work. Only materials and contractor labour are deductible. If you paint the property yourself, you can claim the paint. You can't claim your time.

Q: What happens if I claim an expense and HMRC questions it? A: That's why records matter. You need to show the expense is wholly and exclusively for letting purposes. If HMRC isn't satisfied, they can disallow it and demand back-tax plus interest. Disputed claims can turn expensive quickly.

Q: Can I claim capital improvements like a new kitchen or bathroom? A: Capital improvements (adding new features or significantly upgrading) are not deductible against rental income. However, they increase the property's capital value and have relevance for Capital Gains Tax when you sell. So while not deductible for income tax, they may reduce your CGT liability.

Q: Should I use a company or sole trader structure? A: This depends on your tax rate, mortgage structure, and portfolio scale. Higher-rate taxpayers (40%+) with substantial mortgages often find company structures more tax-efficient because mortgage interest remains fully deductible at company level. Basic-rate taxpayers typically don't see a benefit. This is complex—discuss with a specialist property accountant before making changes. The wrong structure costs thousands over time.
