The True Cost of Being a Landlord in the UK (2026)

Last updated: 8 October 2026 · Next review: April 2027

The rent looks like income. But by the time the mortgage, insurance, repairs, safety checks, empty weeks, agent fees and tax have come out, the money you actually keep can be a fraction of it. Industry research published in January 2026 found that running costs took around 25% of gross rental income for typical landlords and 45% for HMO landlords (Pegasus Insight research).

This guide goes through every cost of being a landlord in England, with 2026 figures and a source for each one. We won’t give you one “average cost of being a landlord”, because your mortgage, location and property type change the answer too much. Instead, you’ll see each cost, what drives it, and how to estimate yours — or you can go straight to the landlord cost calculator.

Summary: every cost at a glance

1. Upfront costs: Stamp Duty and buying

If you’re buying a property to let and you already own a home, you’ll usually pay the higher rates of Stamp Duty Land Tax: the standard rates plus 5 percentage points in each band. The surcharge rose from 3% to 5% on 31 October 2024.

Worked example (England): on a £220,000 buy-to-let, you’d pay 5% on the first £125,000 (£6,250) and 7% on the next £95,000 (£6,650) — £12,900 in total, using the GOV.UK residential rate bands. Add legal fees, surveys and any mortgage arrangement fees on top.

2. Mortgage costs — and the tax rule that catches people out

For most landlords, the mortgage is the largest single cost. Your payment depends on the loan size, rate and whether it’s interest-only or repayment.

The important point is tax. Since April 2020, individual landlords can’t deduct mortgage interest from rental income in the normal way. According to GOV.UK, relief on residential finance costs is restricted to the basic rate of income tax — a 20% tax credit. If you’re a higher-rate taxpayer, you may pay tax on rental “profit” that doesn’t feel like profit once the mortgage is paid.

3. Landlord insurance

The median landlord paid £253.42 a year for buildings and liability cover and £288.48 with contents, according to Simply Business customer data for June–August 2026 published on MoneySuperMarket. Alan Boswell Group’s 2026 quote data gives a median of £284.75. Location makes a huge difference: from £73 a year in Hereford (HR4) to £1,470 in Hampstead (NW3) for a terraced house. Full breakdown: landlord insurance cost.

4. Safety certificates and compliance

These are legal requirements with serious penalties:

• Gas safety check — every year, by a Gas Safe registered engineer. Typically £60–£120 for a single boiler, up to £200 for multi-appliance properties.
• EICR — at least every five years. Typically £150–£250 for a 2–3 bed house. Penalty for non-compliance: up to £40,000.
• EPC — every ten years; minimum Band E. Around £45–£85 on average, or £70–£120 for a 2–3 bed house. Penalty up to £5,000.
• Smoke and CO alarms — on every storey and in rooms with fixed combustion appliances. Penalty up to £5,000.
• PRS database — from 15 December 2026, £65 per property per year.

Spread over their lifetimes, the certificates and PRS fee typically add up to roughly £160–£250 a year for a standard house, before any remedial work. See landlord certificate costs.

5. Maintenance and repairs

Maintenance is usually the biggest cost after the mortgage, and the hardest to predict. The common planning rule is to budget around 1% of the property’s value a year.

More recent data suggests costs are rising. Pegasus Insight’s Landlord Trends Q3 2025 research, reported in January 2026, found maintenance and repairs made up 31–39% of landlords’ total portfolio spending, depending on property type. See our full guide to landlord maintenance costs.

6. Void periods

Every week without a tenant is a week of mortgage and bills with no rent. Rushbrook research reported by The Intermediary in September 2026 found:

• the average void lasted 23.2 days in 2026, up from 17.5 days in 2023;
• the average cost of a void was £1,097, up almost 58% from £696 in 2023;
• in cash terms voids cost most in London (£1,357) and least in the North East (£612).

With tenants now on rolling periodic tenancies under the Renters’ Rights Act, allowing for voids in your budget is more important than ever.

7. Letting agent fees

If you use an agent, this can be one of your biggest costs. Purplebricks’ guide for landlords gives these typical ranges:

Example: on £1,200 a month rent, full management at 12% plus VAT costs about £2,074 a year. Self-managing saves that money but costs your time, and you take on every compliance deadline yourself. Letting agent fees are an allowable expense for tax.

8. Software and Making Tax Digital

Landlords with qualifying income over £50,000 have had to use Making Tax Digital since April 2026, extending to £30,000 in 2027 and £20,000 in 2028. Some landlord apps are free for up to three properties; paid plans typically cost £12–£40 a month for small and mid-sized portfolios. See landlord software prices. Late submissions can lead to MTD penalties.

9. Optional protection: rent guarantee insurance

With the rent-arrears possession ground now requiring three months’ arrears, more landlords are considering rent guarantee cover. Simply Business example quotes range from about £14.46 to £18.33 a month (roughly £174–£220 a year for a typical house; the cheapest policies start lower, so we use £90–£220 as the overall range). See rent guarantee insurance.

10. HMO costs

Houses in multiple occupation carry extra costs: a council licence (e.g. £895 for up to five bedrooms in South Cambridgeshire), higher insurance, bills and more maintenance. Pegasus Insight’s research found running costs took 45% of gross rental income for HMO landlords, compared with 25% for others. See HMO licence cost.

11. Income tax

Rental profit is added to your other income and taxed at your marginal rate. You can deduct allowable expenses that are wholly and exclusively for the letting, including repairs and maintenance, insurance, letting agent fees, accountant fees, ground rent and service charges, and advertising. GOV.UK also sets out:

• a £1,000 property income allowance (use it instead of claiming expenses if your costs are very low);
• replacement of domestic items relief for replacing furniture and appliances (not the first purchase);
• the 20% basic-rate credit for mortgage interest.

Capital improvements (as opposed to repairs) aren’t deductible against rental income.

Putting it together: a worked example

A £220,000 property let at £1,200 a month, with a £650 monthly mortgage payment, self-managed:

Add full management at 12% + VAT and the figure falls to about £1,040 — before tax. That’s the gap between headline rent and real return that this site exists to explain. Try your own numbers in the calculator.

How to reduce your costs

• Re-quote insurance every year — the gap between insurers for the same property can exceed 70%.
• Bundle safety checks (gas check plus boiler service) and book early to avoid rush fees.
• Plan maintenance between tenancies to reduce voids.
• Review your agent’s fee and what you get for it; consider tenant-find only if you can manage day to day.
• Claim every allowable expense and keep digital records.
• Keep compliant — one penalty can wipe out a year’s profit.

Frequently asked questions

How much does it cost to be a landlord per year? It depends mostly on your mortgage. Excluding the mortgage, a typical single-let house might carry £2,500–£3,500 a year in insurance, compliance and maintenance, plus voids and any agent fees. Use the calculator for your figures.

What percentage of rent goes on costs? Pegasus Insight’s research found running costs averaged around 25% of gross rental income for non-HMO landlords and 45% for HMO landlords. The research doesn’t break out exactly which costs are included, so treat it as a broad guide.

What are the hidden costs of being a landlord? Void periods, maintenance spikes, compliance renewals, agent renewal fees, the Section 24 tax restriction and penalties for missed deadlines.

Are landlord costs tax-deductible? Most running costs are, if wholly and exclusively for the letting. Mortgage interest gets a 20% tax credit instead of a full deduction.
