How much does letting agent software cost in the UK?
Updated
Three suppliers print a number. They print it in three different units, which is the part that catches agencies out.
The prices we could actually read
| System | Published price | Charged per |
|---|---|---|
| Apex27 | £35 per user per month, excluding VAT | User. Sales, lettings, land, commercial and auctions included |
| PayProp | Licence from £79 a month, plus under 1% of processing volume, plus £600 to £2,000 setup | Volume of rent processed, with a licence floor |
| Arthur Online, Standard | From £82.50 a month, including 55 units at £1.50 per unit | Unit under management, billed annually |
| Arthur Online, Professional | From £96.00 a month, including 60 units at £1.60 per unit | Unit under management, billed annually |
| Arthur Online, Enterprise | From £126.00 a month, including 70 units at £1.80 per unit | Unit under management, billed annually |
| Acquaint CRM website product | £1,000 plus £41.15 a month plus VAT | The website, not the CRM. The CRM itself is quote only |
Every figure above was read on the supplier's own pricing page on 15 August 2026 and is reproduced, not estimated. Apex27 and Acquaint state their figures exclude VAT; the others do not say either way on the pages we read. Check the supplier's page before you buy.
Three units, three completely different bills
A five-person agency managing 300 units pays for five seats under Apex27, for 300 units under Arthur Online, and a percentage of whatever rent it processes under PayProp. Grow the portfolio without hiring and the per-user bill does not move while the per-unit bill does. Hire two administrators without growing the portfolio and the opposite happens. Before you compare two quotes, write down your headcount, your units under management and your annual rent processed, and ask every supplier to price all three.
What moves a quote from the five that do not publish
- Properties under management
- Client accounting as a module
- Setup and migration
- Websites and portals
- Messaging and eSigning
- Multiple entities
A price behind a demo is not a red flag, but it is information
Five of the eight systems here quote rather than publish, and they include several of the largest platforms in UK lettings. A platform priced on properties under management genuinely cannot print one number. It does mean you cannot shortlist on cost until you have given a salesperson your portfolio figures, and it means the price is negotiable, which a published one is not. Ask for the monthly figure, the unit, whether client accounting is inside it, the migration fee and the cost of leaving, in the first call.
