Tax-Deductible Expenses Every Teesside Landlord Should Know About

One of the most common questions we hear from landlords across Middlesbrough and Teesside is a simple one: what exactly can I claim against my rental income? The answer can make a genuine difference to your bottom line. Many landlords — particularly those managing one or two properties — are paying more tax than they need to because they are not claiming all the expenses they are entitled to.

HMRC allows landlords to deduct a wide range of costs from their rental income before calculating the tax owed. Understanding these allowable expenses is not about aggressive tax planning. It is about knowing the rules and making sure you are not leaving money on the table.

How Rental Income Tax Works

Before we look at specific deductions, it helps to understand the basic structure. Rental income is added to your other income and taxed at your marginal rate — 20% for basic rate taxpayers, 40% for higher rate, and 45% for additional rate.

However, you only pay tax on your profit, not your total 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 pay.

For a Middlesbrough landlord earning £7,200 per year in rent from a single property, claiming £3,000 in allowable expenses reduces the taxable amount to £4,200. For a basic rate taxpayer, that is a saving of £600 per year — money that can go straight back into maintaining or improving the property.

Letting Agent Fees

If you use a letting agent to manage your property — and for most Middlesbrough landlords, this is the most cost-effective approach — the management fees are fully deductible. This includes the monthly management percentage, tenant-find fees, and any additional charges for services like inventory checks or property inspections.

For a typical Teesside property managed at 10% of rent, this could represent £600 to £800 per year in deductible costs.

Repairs and Maintenance

This is often the largest category of allowable expenses. You can claim the cost of repairing or maintaining your property, including plumbing repairs, electrical work, roof repairs, repainting, and replacing broken fixtures.

The key distinction HMRC makes is between repairs and improvements. Replacing a broken boiler with a like-for-like equivalent is a repair and fully deductible. Upgrading from a standard boiler to a premium system with additional features could be classed as an improvement, which is not deductible as a revenue expense. Replacing single-glazed windows with double glazing is an improvement. Replacing broken double-glazed windows with new double-glazed windows is a repair.

For Teesside properties — many of which are Victorian or Edwardian terraces — maintenance costs can be significant. Claiming them properly makes a real difference.

Insurance Premiums

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

A typical landlord insurance policy for a Middlesbrough property costs between £150 and £350 per year, depending on the property type and level of cover. Every penny of that is an allowable expense.

Gas Safety, Electrical Inspections, and EPC Costs

All mandatory safety compliance costs are deductible. This includes your annual Gas Safety Certificate (CP12), your five-yearly Electrical Installation Condition Report (EICR), any remedial electrical work required to meet standards, Legionella risk assessments, and the cost of your Energy Performance Certificate (EPC).

For a Middlesbrough landlord, these costs typically add up to £200 to £400 per year when averaged across the inspection cycles.

Accountancy and Legal Fees

If you use an accountant to prepare your self-assessment tax return — which we strongly recommend — those fees are deductible, at least the portion related to your rental income. Legal fees for renewing tenancy agreements, drawing up new tenancies, or dealing with tenant disputes are also 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 when you eventually sell.

Council Tax and Utility Bills During Void Periods

When your property is empty between tenancies, you as the landlord are responsible for council tax and any utility bills. These costs during void periods are deductible. Middlesbrough Council may offer a council tax discount for empty properties for a limited period, but any amount you do pay is an allowable expense.

This is particularly relevant if you are carrying out refurbishment work between tenants. The council tax and utility costs during that period can all be claimed.

Travel Costs

If you travel to your Middlesbrough rental property for management purposes — collecting rent, inspecting the property, meeting contractors, dealing with tenant issues — those travel costs are deductible. You can claim mileage at HMRC's approved rate of 45p per mile for the first 10,000 miles, or the actual cost of fuel, parking, and tolls.

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

The Replacement of Domestic Items Relief

Since April 2016, landlords have been able to claim the cost of replacing furnishings in a rental property. This applies to furniture, appliances, kitchenware, and soft furnishings — but only when you are replacing an existing item, not furnishing a property for the first time.

If you replace a washing machine, cooker, fridge, sofa, or bed in your Middlesbrough rental property, the cost of the replacement item is deductible. You claim the cost of a like-for-like replacement; if you upgrade, you can only deduct what an equivalent replacement would have cost.

Mortgage Interest — The Tax Credit

This one is important and widely misunderstood. 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, this change significantly increased the effective tax on rental income. If you are a 40% taxpayer with substantial mortgage interest, the restriction means you are effectively taxed on income that is being used to service debt.

This is one of the reasons many higher-rate taxpaying landlords have moved their properties into limited companies, where mortgage interest remains fully deductible. Whether that structure is right for you depends on your individual circumstances — it is worth discussing with a specialist property accountant.

Keeping Records

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 travel to the property. Good record-keeping is not just about compliance — it ensures you claim everything you are entitled to and can support those claims if HMRC ever asks questions.

Professional Advice Makes a Difference

Tax rules change, and individual circumstances vary. What we have outlined here covers the main categories, but there may be additional deductions available depending on your specific situation — particularly if you own multiple properties, are considering incorporation, or are planning significant refurbishment work.
