First-time landlord checklist — UK 2026

Stage 1 — Before you buy

Decide your strategy

Single let, HMO, student let, holiday let — each has different yield, finance, tax and regulatory profiles. Holiday lets lost their preferential tax treatment in April 2025 (Section 24 now applies); HMOs offer much higher gross yields but bigger management workload and stricter licensing. Most first-time landlords start with a simple single let.

Pick a location

Look at gross rental yield, tenant demand, capital growth potential and regulatory burden. Northern England and Scotland generally offer 7–10% gross yields; London and the South East are 3–5% with capital growth doing more of the work. Use our rental yield calculator to model the net position once expenses, voids and Section 24 are factored in.

Personal vs limited company

For a single property where your other income is below the higher-rate threshold, personal ownership is usually simpler. For higher-rate taxpayers planning to hold multiple highly-leveraged properties long-term, a limited company can save significantly on tax — though mortgage rates are higher and the structure is more expensive to run. Don't incorporate without modelling it through. See our Section 24 guide for the maths.

Budget the full purchase cost

• Deposit: minimum 25% for most BTL mortgages.
• SDLT: 5% additional dwelling surcharge applies. On a £200k purchase that's £11,500. Model it with our stamp duty calculator.
• Mortgage arrangement fee: typically £999–£2,500 for BTL products.
• Solicitor fees: £1,200–£2,000 for a straightforward purchase.
• Survey: £400–£800 for a HomeBuyer report; more for a full structural survey.
• Initial works: budget at least one month's rent for paint, clean, certificates and minor remediation before first let.

Stage 2 — Mortgage and purchase

Speak to a BTL broker

BTL mortgages have completely different rules from residential. Brokers know which lenders accept first-time landlords (many don't), which are ICR-friendly, and which suit limited companies. The whole-of-market brokerage takes a fee (£500–£1,500) or a commission from the lender.

Run the ICR stress test before you commit

BTL lenders apply an Interest Cover Ratio (ICR) test — typically 125% for basic-rate landlords or limited companies, 145% for higher-rate. Use our BTL mortgage calculator to check whether the rent passes before you commit to the property. Getting refused mid-purchase is expensive.

Check HMO and selective licensing

Run the postcode through our HMO licence checker before exchange. A property in a selective licensing area carries an annual cost you'd miss otherwise. An HMO purchase needs licensing budget and minimum bedroom sizes verifying.

Stage 3 — Set up the property

• Landlord insurance— specialist policy covering buildings, landlord's contents, public liability. Standard home insurance won't cover let property. Optional add-ons: rent guarantee, legal expenses, emergency cover.
• Gas Safety Certificate (CP12)— annual, mandatory for any property with gas appliances. Get it before tenancy starts. Must be done by a Gas Safe registered engineer.
• EICR (Electrical Installation Condition Report)— 5-yearly, mandatory since 2020. Must be carried out by a qualified electrician. Result must be Satisfactory before letting.
• EPC (Energy Performance Certificate)— minimum E rating to let (current MEES rules). EPC must be valid (10 years from issue). Tightening to C proposed for new tenancies from 2028.
• Smoke alarms— one on every storey used as living accommodation. Carbon monoxide alarms in every room with a fixed combustion appliance (excluding gas cookers).
• Fire risk assessment— required for HMOs and converted flats (Section 257 HMOs).
• Licence (if needed)— apply for HMO and/or selective licence before letting. Letting an unlicensed licensable property is an offence.

Stage 4 — Find a tenant

• Advertise a specific rent— the Renters' Rights Act bans accepting offers above your advertised rent. No bidding wars.
• Reference checks— income, employment, prior landlord reference, credit check. Either DIY (cheap, slower) or via a referencing service (£20–£40 per applicant).
• Right to Rent check— mandatory. Verify every adult occupant's right to be in the UK. Keep copies of documents. Failure to check = up to £20,000 civil penalty per occupant (raised in February 2024).
• Don't discriminate— the Act bans blanket rejection of tenants with children or on benefits. Reject on the basis of evidence (failed affordability, bad reference) not protected characteristics.

Stage 5 — Start the tenancy

• Use a current AT/AST template— under the Renters' Rights Act, all assured tenancies are now periodic with no fixed term. Old AST templates with fixed-term clauses won't reflect the current legal position.
• Protect the deposit within 30 days— must go into one of the three government-approved schemes (DPS, MyDeposits, TDS). Provide the tenant with prescribed information. Deposit cap: 5 weeks' rent under £50k annual rent, 6 weeks above.
• Serve the Renters' Rights Act Information Sheet 2026— the official GOV.UK document (download from gov.uk and send as a PDF attachment, not a link). Required by law.
• Give the EPC, Gas Safety and EICR certificates to the tenant.
• Take a comprehensive check-in inventory— photos of every room, condition of every fixture. Sign jointly. This is your defence against deposit disputes.

Stage 6 — Ongoing operations

• Collect rent on a defined dayvia standing order. Track receipts and chase any late payments promptly — arrears at 3 months trigger a Section 8 Ground 8 mandatory possession route.
• Track every certificate's expiry— gas (annual), EICR (5-yearly), EPC (10-yearly), fire risk assessment (annual for HMOs), PAT testing (where applicable). Missing one is a licence breach and a tenancy-management failure.
• Respond to maintenance promptly— the Decent Homes Standard and Awaab's Law are being phased in for the PRS, with statutory timescales for hazard response. Damp and mould complaints have a defined response window once fully in force.
• Annual rent reviews via Section 13 notice— no more than once per 12 months, must be market rate. Tenant can challenge at the First-tier Tribunal.
• Renew certificates and licences well before expiry.

Stage 7 — Tax and reporting

• Register with HMRC for Self Assessment— by 5 October following the tax year in which you first received rent. Property income goes on the SA105 supplementary pages.
• Keep digital records from day one— even if you're below the MTD ITSA threshold today, you'll be in scope within 1-2 years as thresholds drop to £30k and £20k. Building the habit now is much easier than digitising paper later.
• Understand Section 24— you can't deduct mortgage interest from rental income, only claim a 20% tax credit. See our Section 24 guide for worked examples.
• MTD ITSA from 6 April 2026 if your gross rent + sole-trader income exceeds £50,000 in 2024/25. Quarterly digital returns to HMRC. See our MTD ITSA guide.
• File Self Assessment by 31 January following the tax year. Pay tax due by the same date (with payments on account on 31 January and 31 July).

FAQ

Do I need to register with HMRC even if I make a loss?

Yes. Property income (gross) above £1,000 a year requires Self Assessment registration, even if your taxable profit is nil or negative. Losses can be carried forward against future rental profits.

Can I use a regular residential mortgage to rent out a property?

No — that's mortgage fraud. Residential mortgages explicitly prohibit letting. Switch to a BTL product before letting begins; some lenders offer “consent to let” for a temporary period (e.g. moving abroad) but never assume.

Should I use a letting agent or self-manage?

Full-management agents typically charge 10–15% of rent. For a single local property it's usually cheaper to self-manage if you have time. For multiple properties, remote ownership, or no spare time, an agent is worth it. Hybrid models (let-only: agent finds the tenant, you manage; or rent-collection-only) can balance the trade-off.

What's the single biggest mistake new landlords make?

Two contenders. First: under-budgeting voids and maintenance — properties have empty periods, boilers break, and tenants damage things. Run the numbers with realistic allowances (4-8% void allowance, 1 month's rent in maintenance reserve per property per year). Second: assuming residential-property habits transfer — BTL tax, regulation, mortgage and insurance rules are all different.
