Best letting agent software in 2026 – 7 UK platforms compared

Lettings in England changed overnight on 1 May 2026, when the first phase of the Renters’ Rights Act 2025 abolished Section 21 evictions and moved most tenancies onto rolling periodic agreements. Rent reviews, notice periods, tenant requests and landlord reporting all now follow new rules, and every one of those workflows runs through an agency’s systems. For lettings teams, the best letting agent software is no longer simply a productivity tool. It is the record that proves compliance.

This guide compares seven of the best letting agent software platforms for UK agencies in 2026, explains how they were selected and offers lettings directors a framework for matching a platform to their portfolio, compliance obligations and budget. The focus throughout is the lettings and property management side of the agency rather than sales progression.

The short answer: The best letting agent software for a UK agency depends on how many tenancies you manage, whether you hold client money and whether you need sales and lettings in one system. MRI Software provides lettings, property management, client accounting and workflows related to the Renters’ Rights Act in one platform. Acquaint CRM, agentOS, AgentPro, Estates IT, Expert Agent and Reapit complete the shortlist, ranging from all-modules-included systems for independent agencies to enterprise platforms for large multi-branch businesses.

What is letting agent software?

Letting agent software is a platform that manages the full tenancy lifecycle for a lettings or property management business: marketing a property, progressing applicants, generating and signing agreements, collecting rent, paying landlords, handling maintenance and tracking compliance. Buyers search for it under many names.

What separates lettings platforms from generic CRMs is that the work never ends at “agreed.” A sale completes once; a tenancy generates rent, statements, certificates, inspections and maintenance jobs every month for years. Good letting agent software handles:

• Tenancy progression: applications, referencing, Right to Rent checks, agreements and move-in
• Client accounting: rent collection, reconciliation, landlord payments, fees and statements
• Property management: maintenance, contractors, inspections and certificate renewals
• Landlord and tenant self-service: portals for statements, documents, payments and repair requests
• Compliance tracking: deposits, gas safety, EICR, EPC and the new periodic tenancy rules

The market is large and heavily regulated. The private rented sector accounts for around 4.7 million households, or 19% of all households in England, according to the English Housing Survey 2024 to 2025. Every one of those tenancies carries obligations that lettings software is expected to track.

How we selected the best letting agent software on this list

Many lists in this category are published by suppliers and place their own products first, with limited explanation of how the rest of the field was chosen. This list uses a simple overlap method instead, so the selection criteria are clear.

Two widely read UK roundups of agency software were cross-referenced: Art Division’s guide to CRM software for estate and letting agents¹, which lists 18 providers, and Fixflo’s guide to the best property management software systems in the UK², which lists 16. Only platforms named on both lists were included.

That overlap produced seven suppliers, all of which — according to their published materials — offer lettings, property management and client accounting functionality, so no further exclusions were needed. Suppliers that appeared on only one list were left out, which means some tools are not covered here.

MRI Software is covered first because it is the platform we can describe in the most depth. The remaining six follow in alphabetical order, which is not a ranking. The result is a shortlist of the best letting agent software UK agencies are likely to encounter when they assess their options.

Why 2026 changed what letting agent software needs to do

Letting agent software must now support several regulatory changes that landed within months of each other. A platform that handled fixed-term ASTs well in 2024 may need reconfiguring, or replacing, to cope with the 2026 rulebook. The biggest shifts are:

• Periodic tenancies by default: since 1 May 2026, most new and existing private tenancies are assured periodic tenancies, rent increases are limited to once a year through the section 13 process, and agents cannot accept bids above the advertised rent or ask for more than one month’s rent in advance.
• A PRS database and ombudsman: the same roadmap confirms that the private rented sector database begins rolling out from late 2026, with mandatory landlord membership of a new ombudsman expected in 2028.
• Making Tax Digital: landlords with qualifying income over £50,000 have had to keep digital records and send quarterly updates since 6 April 2026, with the threshold falling to £30,000 in 2027, according to HMRC’s Making Tax Digital guidance. Landlords increasingly expect agency statements to feed those records cleanly.
• Anti-money laundering: letting agency businesses handling rents at or above the supervision threshold must register with HMRC, and HMRC’s supervision handbook confirms the threshold moved from 10,000 euros to £10,000 a month from 30 June 2026.
• Client money and deposits: agents in England who hold client money have had to belong to an approved client money protection scheme since April 2019, and deposits must still be protected in a government-approved scheme within 30 days.

The practical upshot is that compliance can no longer live in a spreadsheet alongside the CRM. Rent reviews, notices, deposit records and audit trails all need to sit in the same system as the tenancy itself.

What to look for in letting agent CRM systems

Letting agent CRM systems commonly connect tenancy data, money and maintenance so that information entered once flows to where it is needed. When comparing lettings CRM platforms side by side with alternatives, these are the capabilities to consider:

1. Periodic tenancy and rent review workflows: bulk conversion of legacy tenancies, section 13 notice scheduling and a clear audit trail for every rent change.
2. Integrated client accounting: bank statement import, automated reconciliation, landlord payment runs, non-resident landlord (NRL) tax and statements, without re-keying into a separate package.
3. Compliance tracking: expiry alerts for gas safety, EICR and EPC certificates, deposit protection status and Right to Rent records.
4. Maintenance and contractor management: online repair reporting, works orders, quotes, landlord approvals and contractor invoicing.
5. Landlord and tenant portals: self-service access to statements, documents, payments and requests, which cuts inbound calls and emails.
6. Digital signing and referencing: e-signed agreements and connected referencing, so applicants can move from enquiry to move-in without paper.
7. Portal and partner integrations: feeds to the major property portals, plus connections to deposit, inventory and referencing providers.
8. Reporting: branch and portfolio dashboards for arrears, voids, renewals and fee income.

A ten-property agency rarely needs every item on this list, but a multi-branch lettings business with thousands of managed units cannot function without most of them. Use the list to separate must-haves from nice-to-haves before booking demonstrations with any letting agency CRM supplier.

The 7 best letting agent software platforms for 2026

Each platform below is summarised with its lettings features and the type of agency it tends to suit, based on the supplier’s published product information. Descriptions are informational and do not constitute endorsements. Pricing is noted only where the supplier publishes it.

1. MRI Software

MRI Software brings lettings, property management, client accounting and sales together in MRI Engage CRM, the estate agent software formerly known as MRI Sales & Lettings. On the lettings side, MRI’s lettings software supports applicant self-service from enquiry to move-in, then manages tenancies through renewals, rent reviews and the end-of-tenancy processes.

MRI Software describes specific workflows for the Renters’ Rights Act in MRI’s guide to preparing for the Act:

• Periodic tenancy conversion: existing tenancies can be converted to periodic in bulk, and new tenancies are set up as periodic automatically
• Rent review dashboard: proposed increases are benchmarked against comparable data and tracked from notice to outcome, with rent charges scheduled to match the required notice period
• Tenant requests and complaints: pet and other requests are submitted through the tenant portal, and complaints are logged and time-stamped so teams can meet response targets

The money side is handled by MRI’s property accounting software, which manages landlord income and expenditure, NRL tax, landlord VAT and supplier payments. Tenants and residents can use MRI Software’s resident portal for updates, payments and repairs, agreements can be signed with MRI Secure Sign, and the platform connects with property management software, portals, and partners through MRI’s integrations network.

• Best fit: independent and multi-branch agencies seeking sales and lettings software with client accounting and workflows related to the Renters’ Rights Act in one platform, with optional modules such as block management or build-to-rent

2. Acquaint CRM

Acquaint CRM³ is an estate and letting agent system that handles sales, full lettings, property management and client accounting in a single platform. On the lettings side, it covers deposits under custodial and insured schemes, rent demands and arrears, automated landlord statements and batch payments to landlords and contractors.

• Client accounting: double-entry client accounts, bank reconciliation and non-resident landlord tax for the UK and Ireland
• Property management: works orders, online tenant maintenance requests, certificate expiry reminders, inspections, rent reviews and key management with a full audit trail
• Pricing model: every plan includes all modules, with no set-up fees and a rolling monthly contract⁴, while SMS, e-signing and AI features run on pay-as-you-go credits per the supplier’s published pricing
• Best fit: independent agencies that want every lettings module included as standard without a long-term commitment

3. agentOS

agentOS⁵ is a customisable CRM covering estate agency, lettings, property management, client accounting and inspections. Its lettings toolkit includes online tenancy applications, integrated AML and credit checks, e-signatures, landlord portals, online maintenance reporting and a contractor app, alongside certificate and compliance tracking.

• Client accounting: an Open Banking connection reconciles the client account, registers deposits and manages rent
• Managed accounting option: agentOS states it has offered client accounting services since 2004, and its agentPay service⁶ ranges from a self-service app to a fully managed option that handles rent chasing, deposit registration and Section 19 reports for HMRC
• Best fit: agencies that want to outsource some or all of their client accounting alongside their lettings CRM

4. AgentPro

AgentPro⁷ is a sales and lettings system sold in three packages. Full lettings functionality, including tenancy agreement creation, rent reminders, tenant invoicing, statements and maintenance job management, comes with the Gold and Platinum packages, along with double-entry client accounts, bank reconciliation and VAT return calculation.

• Tax reporting: HMRC rent analysis for resident and non-resident landlords
• Best fit: lettings-heavy agencies that want traditional, in-depth client accounting and a choice of desktop or cloud deployment

As with any long-established platform, ask to see that notice and tenancy document templates have been updated for the possession rules that took effect in May 2026.

6. Expert Agent

Expert Agent¹⁰ has supplied agency software since 1988 and reports nearly 2,300 member branches. It runs sales, lettings and lettings accounts in one product with a shared diary and task list, and services ordered through its MarketPlace, such as referencing and EPCs, upload automatically to the relevant property and tenancy records.

The table below summarises how each platform approaches the core lettings workflows. Use it to narrow a shortlist before booking demonstrations.

How much does letting agent software cost

Letting agent software ranges from a little over £100 a month for a small agency to bespoke enterprise contracts for large multi-branch businesses. Only one of the seven platforms on this list publishes full package prices, so for most suppliers the true cost only becomes clear after a demonstration and quotation.

Pricing usually follows one or more of these models:

• Per user: a monthly fee for each member of staff, common for CRM-led platforms
• Per property or tenancy: a fee that scales with managed units or collected rents, common for property management and client accounting modules
• Per branch or package: a fixed monthly fee for each office, often with a set number of users included
• Add-ons and credits: portals, e-signing, referencing, SMS and AI features charged separately or on pay-as-you-go credits
• Contract length: anything from rolling monthly terms to minimum commitments of two years or more

Licence fees are rarely the whole picture. Budget also for data migration from your current system, set-up and training, integration fees, usage-based costs for referencing or e-signatures, and the staff time needed to clean data before go-live. Migration deserves particular attention: Expert Agent, for example, notes that it can migrate most data from an agency’s old software but cannot transfer lettings financial transactions¹⁴. Ask every supplier the same question, because historic client accounting data is usually the hardest thing to move.

The return comes mostly from time saved and risk avoided. A simple way to estimate it is to multiply the hours your team spends each month on manual reconciliation, statement preparation, certificate chasing and repair coordination by a fully loaded hourly cost, then compare that figure with the monthly subscription. Factoring in the potential cost of a compliance failure, such as an unprotected deposit or a missed rent review notice, the time and risk savings can offset subscription costs for many agencies.

How to choose software for letting agents

The right choice depends on the shape of your business more than on any single feature. Start with these questions:

1. How many tenancies do you manage, and how many are fully managed? Agencies with mostly let-only instructions can live with lighter tools, while fully managed portfolios need integrated client accounting and maintenance.
2. Do you need sales and lettings in one system? If your agency runs both, an all-in-one sales and lettings software platform avoids duplicate landlord and property records.
3. Who reconciles client money today? If reconciliation still happens in a spreadsheet, prioritise platforms with bank statement import and automated matching, or consider a managed accounting service.
4. How ready are your workflows for the Renters’ Rights Act? Ask each supplier to demonstrate periodic tenancy conversion, section 13 notices and complaint tracking live, not on a slide.
5. What will migration involve? Ask how long data migration takes, what history comes across, and what happens to your data if you leave.

As a rule of thumb, lettings-only agencies with a few hundred units can shortlist the all-modules-included options, while mixed sales and lettings businesses should look closely at connected full-suite platforms. Multi-branch agencies managing thousands of tenancies, or those expanding into block management or build-to-rent, need the reporting depth and accounting controls of enterprise software for letting agency operations. Whichever route you take, insist on a trial or sandbox that uses your own data, because lettings agents software that performs well in a demonstration with sample properties can behave very differently with a real ledger.

Frequently asked questions about letting agent software

Choosing the best letting agent software for what comes next

The Renters’ Rights Act is only the first phase of a longer reform programme, with the PRS database, a landlord ombudsman and new property standards still to come. The best letting agent software may be the platform that keeps tenancy, money and compliance data in one place, so each new rule becomes a configuration change rather than a crisis.

Request demonstrations and, where available, a sandbox environment from shortlisted suppliers to evaluate fit using your own data.
