Estate agent software UK: the whole stack explained
Estate agent software in the UK is not one product but a stack: a CRM at the centre, with portal feeds, a website, diaries, phones, compliance checks, sales progression and now AI plugged into it.
This guide explains each layer, names the main vendors fairly, gives you a selection checklist, and shows where Lettings Quest fits: an AI layer that answers your phone and writes to the CRM you already run, not another CRM.
01 · The stack map
What estate agency software actually covers
Filter by layer. Each card says what the software does, the jobs it takes off a negotiator, and who sells it.
Most UK agencies run several separate systems, even when one of them is sold as “all in one”.
The CRM holds the records. Everything else either feeds it or reads from it.
Vendor names are examples, not endorsements. For the rentals side, see letting agent software.

Maturity is our editorial read of how widely each use is deployed in UK agencies, not a survey figure. Vendors named are examples, not endorsements.
02 · Layer one
The CRM is the centre of gravity
Pick the CRM first. Almost every other choice is constrained by what it connects to.
The main UK estate agency software vendors below all cover sales and lettings, with different strengths in scale, price and how open their systems are to other tools.
We do not rank them. The best estate agency software for a small independent is rarely the best for a large group.
For a deeper look at records, matching and the AI now inside these systems, read our guide to the estate agent CRM.
Examples, not a ranking. Descriptions summarise each vendor’s own positioning; check current features with the vendor.
03 · Layer two
Portal feeds and where enquiries go next
The portal feed is the most important integration your estate agent software has. Watch one enquiry make the round trip.
Your CRM pushes each listing to the portals and pulls enquiries back, so a negotiator sees the lead against the right property.
The weak link is not the feed but the step after it: who replies, how fast, and whether the answer lands back in the CRM.
Rightmove says it had 46 strategic AI initiatives by mid-2026, including conversational search, so buyers now arrive better informed. See Rightmove AI.
04 · Layer three
Most software never picks up the phone
Set your office hours. The strip shows how much of the week your estate agency software is, in effect, switched off for callers.
CRMs, feeds and websites run all night. The phone line usually does not.
Vendors ringing about a valuation on a Sunday evening reach voicemail, and they rarely ring just one agent.
That is the gap an AI receptionist for estate agents closes, with the call summary written into the same CRM as everything else.
Prefer people on the phones? Compare an estate agent answering service.
05 · The big decision
All-in-one suite or best-of-breed stack?
Every agency ends up somewhere between these two. Know which way you lean before you sit through demos.
An all-in-one estate agency management software suite gives you one contract, one login and one support line.
The wider market of specialist tools is mapped in our proptech UK guide.
A best-of-breed stack lets you pick the strongest tool for each job, at the cost of more integrations to maintain.
In practice most agencies run a core suite and add two or three specialist tools where the suite is weakest.
06 · Layer four
Compliance software you cannot skip
Some of your estate agent software exists because the law says so. Check each rule against your stack.
Estate agency businesses fall under the Money Laundering Regulations 2017, so identity and AML checks need an audit trail.
Listings must not mislead or omit material information under the Digital Markets, Competition and Consumers Act 2024, and the CMA can now fine up to 10% of global turnover.
If you draft listings with AI, a person must still check them; see our AI property description generator guide.
Call recordings and AI call summaries are personal data under UK GDPR, and callers must be told when calls may be recorded.
07 · Layer five
The AI layer, and where Lettings Quest fits
Lettings Quest is not a CRM. It is designed to read from your CRM and diary and write back to them.
Your estate agency software stores records well. What it cannot do is hold a conversation with a vendor at 20:00 on a Sunday, when speed to lead matters most.
Lettings Quest answers the call, asks the questions a negotiator would, books the valuation or viewing into the live diary and writes the summary back to the CRM.
Integrations are designed to work with the systems below; what is possible depends on your CRM account and its API, which we confirm on a demo.
08 · Choosing well
The estate agent software selection checklist
Tick what your shortlisted system can prove, not what the sales deck promises. Nothing is stored.
Ask every vendor to demonstrate each point on your own data or a realistic copy of it.
If a vendor cannot show a working export of your records, treat that as a warning, not a detail.
09 · Which kind of stack
Which setup suits your agency?
Four questions. The result suggests a shape of stack and links to the next guide.
There is no single best estate agency software in the UK. There is a best fit for your size, your book and how much change you can take this year.
10 · Switching systems
How to change software without losing a week
A CRM migration is a data project first and a software project second.
The agencies that switch smoothly clean their data before moving it and run the old system read-only for a period.
Add-on tools such as an AI receptionist can be connected after the new CRM is live, so they do not add risk to the move.
