8 Best Landlord Software UK 2026: Complete Comparison

Top picks by situation

Different software suits different landlord situations. Here are our recommendations.

What should landlord software do in 2026?

In 2026, landlord software must do three things it never had to do before: submit quarterly MTD updates to HMRC, maintain the evidence trail the Renters' Rights Act demands, and prepare your records for the PRS Database. Anything that only tracks income and expenses is solving a 2020 problem.

1. Making Tax Digital quarterly submissions

MTD for Income Tax went live on 6 April 2026. If your qualifying property income exceeds £50,000, you are already inside the regime: digital records are mandatory, and your first quarterly update for the 2026-27 tax year covers 6 April to 5 July 2026, due by 7 August 2026. The threshold drops to £30,000 in April 2027 and is expected to reach £20,000 in April 2028, so most landlords with more than one property will be affected within two years.

That changes what "landlord software" means. A tool that produces a tidy year-end summary is no longer enough. Your software needs to keep digital records in an HMRC-acceptable format, map transactions to the correct MTD expense categories, and submit four quarterly updates plus a final declaration each year. Spreadsheets alone do not satisfy the digital-links requirement without bridging software bolted on. See our best MTD software for landlords comparison and our guide to landlord accounting software for MTD for the full detail.

2. Renters' Rights Act record-keeping and notices

Section 21 was abolished on 1 May 2026. Every possession claim now needs documented grounds under Section 8, and every rent increase on a periodic tenancy goes through the Section 13 process. In practice this means your rent payment history, compliance certificates, communication logs and tenancy records have stopped being admin and become potential court evidence.

Good software in 2026 should generate Section 8 notices with the correct grounds and notice periods, produce Section 13 rent increase notices, and keep a dated audit trail of everything that happens in a tenancy. It should also have your property data structured and ready for the PRS Database, the national landlord register launching in late 2026 that all private landlords in England will need to join. Accounting-only tools do none of this.

3. Compliance tracking that actually prevents fines

The baseline has not changed: annual gas safety certificates, EICRs every five years, a valid EPC (minimum band E today, with band C targeted for 2030), smoke and carbon monoxide alarms, deposit protection within 30 days, and licensing where it applies. What has changed is the cost of getting it wrong. An expired gas certificate is not just a fine risk; under the post-Section 21 regime, poor compliance records weaken your position in any Section 8 proceedings and will be visible on the PRS Database.

Software should track every certificate against every property, remind you at 90, 60 and 30 days before expiry, and store the documents themselves so you can produce them on demand.

4. Everything else: tenants, documents, AI

Beyond the regulatory core, the best tools manage tenancies end to end (rent schedules, deposits, renewals), store documents with automatic data extraction, and increasingly use AI to remove the admin entirely. The strongest 2026 pattern is conversational: you upload a tenancy agreement or bank statement and the software reads it, files it and updates your records, rather than presenting you with forty empty fields.

Full comparison table

Here is how the main options compare on the things that matter to UK landlords in 2026: price, MTD for Income Tax, compliance tracking, Renters' Rights Act tools, tenant management, AI capability and free tiers. Spreadsheets are included as the DIY baseline.

Three patterns stand out. First, the accounting specialists (Hammock, RentalBux) handle MTD well but leave compliance, tenancies and the Renters' Rights Act entirely to you. Second, the US-origin and agent-grade tools (Landlord Studio, Arthur Online) manage properties well but are weaker on UK-specific tax and legislation. Third, only the UK-native all-in-one tools cover the full 2026 obligation set in one place. For deeper head-to-heads, see LandlordOS vs Hammock, LandlordOS vs Landlord Studio and our roundup of Landlord Studio alternatives.

Free landlord software options

Several platforms offer genuinely free tiers for landlords with smaller portfolios. Here's what you can get without paying.

Is free software enough?

It depends which free tier you mean. Most free plans are deliberately limited: they cover basic income and expense tracking but hold back the features 2026 actually demands. Check whether the free tier you are considering includes:

• MTD quarterly submissions: Mandatory since 6 April 2026 for landlords with over £50k of property income. On Hammock this requires the £10/month Pro plan.
• Compliance reminders: Gas safety, EICR and EPC expiry alerts typically sit behind paid tiers on accounting-focused tools, or do not exist at all.
• Renters' Rights Act tools: Section 8 and Section 13 notice support is absent from almost every free plan on the market.
• Room to grow: Unit caps (3 units on Landlord Studio) force an upgrade or a migration just as your admin load increases.

LandlordOS is the exception right now because the whole product is free during Early Access, including MTD-ready accounting, compliance tracking and the AI agent. There is no feature wall to hit.

Free vs paid landlord software

Free landlord software falls into three categories: genuinely free products (LandlordOS during Early Access), free tiers designed to upsell you (Hammock, Landlord Studio), and free-for-now products with unconfirmed future pricing (RentalBux). Paid software typically costs £5 to £30 per month and earns its keep through MTD filing, automation and time saved.

What paid software buys you

Across the market, the features most commonly locked behind payment are MTD quarterly submission, automated transaction import, tax reports, compliance reminders and multi-property support. At £5 to £30 per month (£60 to £360 per year), paid software is still cheap relative to the alternatives: a letting agent takes 8 to 12 per cent of rent (£960 to £1,440 per year on a £1,000/month property), and a missed gas safety certificate can cost far more than a decade of subscriptions.

When free is the right answer

Free works when the free product actually covers your obligations. A landlord under the MTD threshold with one property and a good calendar can survive on a basic free tier. A landlord over £50,000 of property income cannot: quarterly MTD submission is non-negotiable and is rarely included free. The honest test is not "what does it cost?" but "does it do everything I am legally required to do this year?"

The Early Access angle

LandlordOS is free during Early Access precisely because the product is still earning its track record. You get the full feature set (compliance, tenancies, MTD-ready accounting, the Ace AI agent) at no cost, and in exchange the product gets real landlord feedback.

Do I need software for one property?

You are not legally required to use software for one property unless your total property income exceeds the MTD threshold, but a single-property landlord carries almost the same compliance load as a portfolio landlord, and a single missed deadline costs the same either way.

One rental property still means an annual gas safety certificate, an EICR every five years, a valid EPC, smoke and carbon monoxide alarms, deposit protection within 30 days with prescribed information served, Right to Rent checks, and possibly selective licensing depending on the council. Since 1 May 2026 it also means keeping records good enough to support a Section 8 claim if the tenancy ever goes wrong, because Section 21 is no longer there to fall back on. And when the PRS Database opens in late 2026, that one property needs registering like any other.

The traditional argument against software for one property was cost: paying £10 to £30 per month to manage a single tenancy felt disproportionate. That argument has weakened on both sides. The obligations have grown (MTD, Renters' Rights Act, PRS Database) while the price floor has dropped to zero: LandlordOS is completely free during Early Access, Hammock and Rentila have free basic tiers, and Landlord Studio is free up to 3 units.

A reasonable rule of thumb: if your property income is over £50,000 you need MTD-capable software full stop. If it is under, free software is still the cheapest insurance you can buy against a £6,000 gas safety fine or a deposit penalty of up to three times the deposit.

Landlord software vs spreadsheets vs accountant

These are not interchangeable. Spreadsheets are free but cannot file MTD updates or send reminders. An accountant gives advice and files returns but does not run your properties day to day. Software does the daily record-keeping and compliance work, and pairs well with an accountant rather than replacing one.

The spreadsheet trap

Spreadsheets fail in three specific ways in 2026. First, MTD: HMRC requires digital records with digital links and quarterly electronic submission, which a spreadsheet can only achieve with bridging software layered on top. Second, memory: a spreadsheet never reminds you that the EICR expires next month. Third, evidence: when you need to show a court a clean rent ledger and communication history for a Section 8 claim, a hand-edited spreadsheet is weaker evidence than a timestamped system of record.

What an accountant is actually for

A good accountant earns their fee on advice: incorporation decisions, capital gains planning, allowable expense edge cases, finance cost restrictions. What they should not be doing in 2026 is typing your transactions into their own system at £100+ per hour. Give them clean software exports instead and spend the saved fees on advice. Many accountants now ask clients to arrive with software-kept records precisely because MTD made shoebox bookkeeping uneconomic.

The practical setup most landlords land on

Software as the system of record (transactions, certificates, tenancies, notices), quarterly MTD updates filed from the software, and an accountant reviewing the year-end position if your affairs are complex. Landlords with one or two simple properties often skip the accountant entirely once the software is doing categorisation and tax summaries. For the full head-to-head, see our guide to landlord accounting software for MTD.

How to choose

Consider your portfolio size, what you need beyond accounting, and whether MTD and the Renters' Rights Act apply to you (for most landlords in 2026, both do).

Questions to ask yourself

• How many properties? 1-5 = simpler tools, 5+ = more comprehensive
• Do you need compliance tracking? Gas, EICR, EPC reminders?
• Does MTD apply to you? Mandatory since 6 April 2026 over £50k of property income, dropping to £30k in April 2027
• Do you need Renters' Rights Act tools? Section 8 grounds, Section 13 rent increases, PRS Database readiness
• What's your budget? Options from free to £30+/month
• Do you work with an accountant? Check what they recommend and what exports they need
