Property management software UK: How to choose the right system

Running a lettings book on spreadsheets and email may seem like the best approach, especially if that’s how you have always done things, but it’s putting your business at risk. 

This is firstly because compliance obligations keep growing, from Right to Rent checks and client money protection (CMP) to Renters' Rights Act reforms. The other reasons are that clients expect faster reporting and clearer communication and team members expect to use a system with premium functionality. To add to this, manual, spreadsheet-based processes that work for a small portfolio of properties break down quickly as that portfolio expands. 

To remain compliant and provide the speed and accuracy your clients expect, you need purpose-built property management software for UK letting agents.

This buyer's guide covers the features that matter, explains how property management software differs from a CRM, and lists the questions to ask before you sign a contract.

What features should I look for in property management software for large estates?

For large estates and growing lettings books, look for property management software that includes everything your team needs to operate smoothly each day and handle task management, maintenance and inspections, compliance tracking and financials. 

At scale, you also need branch-level access permissions, bulk actions and reporting that shows status across the whole portfolio at a glance.

Since 1 May 2026, assured shorthold tenancies in England have converted to assured periodic tenancies, and no fault evictions have been abolished. Any platform you shortlist should already reflect the new tenancy structure, notice rules and possession grounds, and be capable of adapting to future updates.

Need property management software? Look for the following:

• Tenancy management covering tenancy set-up, written statements of terms, rent reviews and notice tracking
• Maintenance management that includes work order logging, contractor quotes and invoices, and records of completed work
• Accounting that supports your client money protection (CMP) scheme obligations.
• Rent collection, reconciliation and arrears tracking, with clear visibility of each tenant's financial position
• Landlord and tenant self-service access for statements, documents and maintenance requests
• Compliance tracking that covers everything from gas safety certificates, EICRs and EPCs to deposit protection and Right to Rent records
• Inspection scheduling and mobile reporting for property managers who are out and about all day
• Portfolio-wide reporting, user permissions and audit trails for agencies with multiple branches
• Overviews of tenant and landlord info, including up to date finances and arrears
• Integration with your CRM so relationships can be managed as well as accounts

In 2026, property management software is the compliance infrastructure that protects your agency's reputation, your landlords and your clients' money. 

Rex PM is one example of a platform built around these requirements, with inspection, maintenance, tenancy and compliance workflows connected to your agency's sales CRM.

What is the best software for property management in the UK?

There is no single best software for property management in the UK, because the right choice depends on portfolio size, agency model and whether you run sales and lettings together. A boutique letting agent with 40 managed properties needs a different system from a multi-branch agency managing 2,000, so match the platform to the portfolio you have now and the one you plan to build.

Most searches for the best property management software UK agencies return the same handful of names. The table below summarises where each typically fits.

A platform built for very large portfolios can be overkill and costly for a boutique letting agency, while a lightweight tool may create bottlenecks as the portfolio grows. 

Agencies that also sell property should make CRM integration a key factor in the decision, since a separate property management solution for lettings means landlord and vendor data living in two places, which can lead to contact double-ups and missed opportunities.

What is the difference between a CRM and property management software?

CRM stands for Customer Relationship Management and does just that, managing contacts, communications, pipelines and follow-up for landlords, tenants, buyers and vendors. It applies to the selling and letting areas of an estate agency.

Property management software helps agencies to oversee properties, tenancies, rent schedules, maintenance, compliance and client accounting. 

Sales and lettings agents use a CRM to log every client interaction and be more proactive with outreach and follow ups, while property managers use property management systems to run each tenancy, from onboarding new landlords to tracking inspections and staying on top of payments.

Problems start when users are constantly forced to switch between systems. When a landlord's details sit in the CRM but their tenancies sit in a separate place, a renewal conversation or certificate expiry can be missed.

A letting agent that runs its CRM and property management platform as one connected system closes the data gap that causes missed follow-ups and compliance oversights. 

Look for a property management platform where landlord records, communications and tenancy data are shared, so negotiators and property managers work from the same information. An integrated estate agency CRM handles the relationship side of that picture.

What are the top-rated estate agent CRM platforms in the UK?

The estate agent CRM platforms most often shortlisted in the UK include Rex Software, Reapit, Alto, Jupix and Dezrez. The best choice for a letting agent is a CRM that connects directly to property management tools.

How to evaluate property management software before signing a contract

The best value property management software is the one that ticks all the right boxes in terms of functionality and is easy to use. Data migration, onboarding, compliance updates, integrations, mobile access and contract terms all count when you’re making a decision.

6 questions to ask a property management software vendor before you sign a contract:

1. How will you migrate our existing tenancy, landlord, tenant and financial data, and who will confirm this is done correctly?
2. Is onboarding and staff training included, or charged separately?
3. Who will update the platform when UK tenancy law changes?
4. Does the platform integrate with our CRM, accounting software and maintenance tools?
5. What is your uptime commitment, and is it written into the contract as a service level agreement?
6. What happens to our data if we leave, in what format do we receive it, and at what cost?

The updated Renters' Rights Act shows how quickly UK tenancy law can change, so a vendor's track record of updating its platform is one of the most important due diligence questions you can ask. 

Ask for specific examples, including release dates, and check how existing clients were informed about changes. Our article on what the Renters' Rights Act means for letting agents covers the obligations in more detail.

Property managers need an app that works when they’re away from their desk, so don’t forget to check mobile access. Contract flexibility matters too: a long minimum term with steep exit fees may reduce your leverage if the platform fails to meet expectations.

Property management software UK agencies can scale with

The right property management software for a UK letting agent manages compliance reliably, scales with the portfolio and connects to the CRM, so client relationships and tenancy management can stay in step. Before you sign:

• Shortlist options based on fit for your portfolio size now and in the future
• Test compliance workflows against current legislation
• Get clear answers on migration, support and exit terms
• Ensure customisability meets your needs

The cost of the wrong property management system is evident when renewals are missed, compliance problems emerge and arrears start to build up.

The ideal property management software will improve visibility across every property, tenancy and transaction, while keeping your property and sales teams aligned and working well together.
