We build EstatAI, which is number one on this list — and we have included every platform we compete with, along with what each of them does better than us. You would find out anyway. EstatAI leads because it answers the question differently: everything else here is a licence you adapt to, and ours is a system built around how your agency already runs. No sponsored placements, no affiliate links.
Most letting agents do not change software because they want better features. They change because something breaks — a compliance date is missed, a landlord statement goes out wrong, or the system cannot do the thing the law now requires. 2026 has handed the industry two of those moments at once.
What Changed in 2026, and Why It Matters to Your System
The Renters' Rights Act took effect on 1 May 2026. Fixed-term assured shorthold tenancies are gone. Every tenancy is periodic, which means your software has to track periodic tenancies rather than end dates, record notices properly, handle annual Section 13 rent reviews, and build the kind of evidence trail a Section 8 case depends on. A system designed around fixed-term expiry dates is working from a data model that no longer matches the law.
Section 21 notices went with them. Possession now runs through Section 8 grounds, which means the evidence your system holds is the evidence your case rests on. Software choice stopped being a question of convenience and became a compliance decision. The commencement regulations are here, and the government guide is here.
Five Questions to Ask Before You Sign Anything
Every demo shows the same dashboard, the same portal feed, the same mobile app. These are the questions that separate the platforms once the demo ends:
- 01Does it track periodic tenancies and Section 13 rent reviews natively, or is that a workaround?
- 02Is client accounting genuinely built in, or is it a bolt-on you will pay for separately?
- 03How long does migration take from your current system, and who does the work?
- 04What is the real average support response time — not the number in the contract?
- 05Who owns your data if you leave, and in what format do you get it back?
The Platforms, Compared
Ordered by category rather than by score — the right answer depends on the size and shape of your book.
EstatAI — built for your agency, white-label
Every other platform here asks your agency to work the way the software works. We build the software around the way your agency already works — your fee structures, your landlord reporting, your branches, your compliance checklist. Put your own brand on it and we stay out of sight entirely, which is why other firms resell it as their own.
- →Built to your workflow after a discovery study, not configured from a template
- →White-label: your name on it, or ours in the background — your choice
- →AI chat widget and Voice AI included, so enquiries are answered outside office hours in 30+ languages
- →Full training for your team, not a login and a help centre
- →Built for the Renters' Rights Act from the start — periodic tenancies, Section 13 reviews, Section 8 evidence
Best for: Agencies that have outgrown off-the-shelf platforms, and firms that want to sell lettings software under their own name.
Cost: Quoted after a discovery study. Most projects land between £1,500 and £4,500.
Alto
Owned by Zoopla and rebranded from CFP in 2020, Alto covers the whole lettings lifecycle in one place — referencing, tenancy agreements, deposit registration, rent collection and maintenance — with direct Zoopla listing integration. It is the default answer for agents who want one system rather than a stack of specialist tools.
- →Full lettings lifecycle in a single platform
- →Direct Zoopla integration and portal feeds
- →Referencing through a Homelet integration
- →Widely used, so staff often arrive already knowing it
Best for: Agencies that want one supplier and one login for everything.
Cost: On application — pricing is quoted per agency.
Reapit
The enterprise incumbent in UK agency software, built for corporate groups with many branches and complex reporting lines. Deep functionality and serious client accounting, at a price and implementation weight to match.
- →Built for multi-branch operations and group reporting
- →Strong client accounting and audit trails
- →Large partner ecosystem
- →Heavier implementation than mid-market platforms
Best for: Corporate groups where the cost of the wrong system exceeds the cost of the right one.
Cost: Enterprise pricing, quoted per group.
Goodlord
Goodlord concentrates on the front end of a tenancy rather than the whole book — referencing, contracts, e-signature, deposit and rent collection — and does that stretch of the process particularly well. Many agencies run it alongside a CRM rather than instead of one.
- →Tenant referencing and e-signed agreements in one flow
- →Deposit registration and rent collection built in
- →Insurance and utility add-ons
- →Usually paired with a separate CRM rather than replacing it
Best for: Agencies whose pain is tenancy set-up admin rather than portfolio management.
Cost: Per-tenancy pricing, quoted per agency.
Fixflo
The clear market leader for UK lettings maintenance, used by more than 1,500 agencies as of 2026 according to the company. Tenants report issues through a branded portal available in 40 languages, and a visual fault-finding guide cuts unnecessary contractor callouts by roughly 30% on Fixflo's own figures. Landlord approvals are timestamped, which matters for Section 20 consultation evidence.
- →Branded tenant reporting portal in 40 languages
- →Fault-finding guide reduces avoidable callouts
- →Timestamped landlord approval trail
- →Affordable even for small books — from around £0.50 per unit per month
Best for: Almost any agency with managed properties. It solves one problem completely.
Cost: From approximately £0.50 per unit per month (Fixflo).
Jupix
A long-established UK agency CRM covering sales and lettings, widely used by independents and small groups. Familiar to a large pool of staff, with the trade-offs you would expect from a mature product: dependable and well understood, less modern than newer entrants.
- →Sales and lettings in one CRM
- →Established portal feeds
- →Large base of experienced users
- →Interface shows its age against newer platforms
Best for: Independents who value familiarity and a known quantity.
Cost: Quoted per agency.
Arthur Online
Frequently recommended for agencies and managers running 30 or more properties, with strong workflow automation across tenants, contractors and owners. Sits somewhere between a landlord tool and a full agency CRM.
- →Strong for portfolios above roughly 30 units
- →Contractor and maintenance workflows
- →Good landlord and owner reporting
- →Less focused on front-end agency sales workflows
Best for: Property managers and lettings-only agencies with a managed book.
Cost: Tiered by unit count.
Dezrez
Formerly Agency Pilot and serving around 1,200 branches, Dezrez is known for open API architecture that lets larger firms plug in their own tools — valuation apps, investor portals, custom dashboards — without waiting for the vendor's roadmap. Its lettings side strengthened considerably after the Rezi acquisition in 2020.
- →Open API for custom integrations
- →Strengthened lettings and property management modules
- →Suits groups with in-house or contracted developers
- →Roughly £120 to £180 per user per month for the full suite
Best for: Groups that want a platform they can extend rather than replace.
Cost: Approximately £120 to £180 per user per month.
PayProp
A specialist in automated rent collection and reconciliation, handling the money side with an accuracy that general CRMs rarely match. Agencies typically run it alongside their main system rather than instead of it.
- →Automated rent collection and reconciliation
- →Landlord statements and commission handling
- →Reduces manual bank-matching considerably
- →A component, not a whole system
Best for: Agencies losing hours a week to reconciliation.
Cost: Percentage-based, quoted per agency.
Acquaint
A long-standing UK CRM aimed at smaller agencies, covering sales and lettings without the price tag of the enterprise platforms. Modest interface, dependable core.
- →Affordable for small books
- →Sales and lettings covered
- →Website and portal feeds available
- →Fewer modern automation features
Best for: One- or two-branch independents watching costs.
Cost: Entry-level pricing, quoted per agency.
AgentOS
Built around lettings rather than treating it as a bolt-on to a sales CRM, with property management, maintenance and accounting handled natively. Regularly recommended for agencies with a substantial managed portfolio.
- →Lettings-first design rather than a sales CRM with lettings added
- →Native property management and accounting
- →Suits growing managed books
- →Less relevant to sales-led agencies
Best for: Agencies whose income is mostly management fees.
Cost: Quoted per agency.
Landlord Vision
Aimed at landlords managing their own portfolios rather than agents managing other people's. Worth knowing precisely so you do not buy it by mistake — it lacks client accounting, remittances and per-landlord fee structures, which are the substance of an agent's obligations.
- →Strong for self-managing portfolio landlords
- →Rent, expenses and compliance reminders
- →Roughly £19.97 to £84.97 per month
- →Not built for agencies handling client money
Best for: Landlords. Agents should look at the platforms above instead.
Cost: Approximately £19.97 to £84.97 per month.
If Your System Cannot Handle Periodic Tenancies Yet
You have two realistic routes. Migrate to a platform that already handles the new rules, accepting that you will adapt your processes to theirs. Or have a system built around how your agency already works, which takes longer to start and fits better afterwards.
We do the second. It begins with a short discovery study of your agency — your fee structures, your landlord reporting, your branches — and ends with a fixed scope, timeline and price before any development starts. Most agency systems come in between £1,500 and £4,500, and typically take 15 to 25 working days from sign-off to going live.

The Gap Every Platform on This List Shares
Compare the feature lists above and you will notice something none of them solve: they all assume somebody is at a desk. A prospective tenant who lands on your website at ten at night, or a landlord calling while your team is out on viewings, meets a contact form or voicemail. The enquiry is logged beautifully — the following morning, by which point they have often called the agency down the road.
That is the gap we built for first: an AI chat widget that answers property and tenancy questions on your website around the clock, and a Voice AI receptionist that takes calls in more than thirty languages, qualifies the enquiry and books the viewing. Both feed the CRM rather than replacing it, so they work alongside whichever platform you land on above.
Which One Should You Choose?
Letting Agent Software FAQs
What is the best letting agent software in the UK for 2026?
There is no single answer, because agencies differ. Alto suits agencies wanting one system for everything; Reapit suits large multi-branch groups; Fixflo handles maintenance better than any general platform; AgentOS suits lettings-first agencies. If nothing off the shelf fits how your agency actually works, having a system built to your workflow — under your own brand if you prefer — is a realistic option that most agents do not know exists.
How has the Renters' Rights Act changed what letting agent software must do?
Since 1 May 2026 there are no fixed-term assured shorthold tenancies to renew. Every tenancy is periodic, which means your system has to track periodic tenancies, serve and record notices, handle annual Section 13 rent reviews and build a Section 8 evidence trail. Software still organised around fixed-term end dates is working from a data model the law has removed, and that is a compliance exposure rather than an inconvenience.
How much does letting agent software cost in the UK?
It varies enormously by category. Specialist components can start under a pound per unit per month; full agency platforms commonly run from around £120 to £180 per user per month; enterprise systems are quoted per group. A system built for your agency works differently again — it is a project cost rather than a subscription, typically between £1,500 and £4,500.
Should a letting agency buy an all-in-one platform or build a stack?
A stack can work well for an agency with an entrenched CRM and a strong bookkeeping operation. The practical test is whether you can report a repair, run a rent review and produce a landlord statement without switching systems. If you cannot, the stack is costing you more in admin time than it saves in licence fees.
Can letting agent software be white-labelled?
The mainstream platforms are sold under their own brands. White-label — where the software carries your name and your client never sees the developer — comes from having it built rather than buying a licence. It is the usual route for agencies offering software to their own landlords, and for proptech firms adding a product line without building a development team.
