Property Management Software Hidden Fees Exposed 2026

One platform's £12 per month plan actually costs £31 per month once you add payment processing fees, bank feed charges, MTD filing costs, and the premium support tier needed to get a response within 48 hours. This is not an outlier. Across 10 UK property management software platforms we analysed in February 2026, the average gap between advertised price and true monthly cost is 42%. Hidden fees are the single biggest reason landlords overpay for software — and the hardest cost to discover before you commit.

This guide identifies and quantifies the 12 most common hidden fees in UK property management software. We calculated the real-world cost of each fee, ranked platforms by pricing transparency, and created a pre-signup checklist so you can calculate the true cost before handing over your card details. For a complete platform pricing comparison, see our 2026 UK pricing report.

The 12 Hidden Fees in Property Management Software

We identified 12 categories of hidden fees across popular UK landlord software platforms. Some platforms charge for just two or three of these; others charge for eight or more. The cumulative effect can double the headline subscription price for landlords who use the full feature set. Each fee below includes the typical cost range and which platforms are most likely to charge it.

1. Payment Processing Fees (2-3.5% Per Transaction)

Payment processing fees are the largest hidden cost for landlords who collect rent through their software. The underlying cost of processing a card payment via Stripe or GoCardless is approximately 1.4-1.5% + 20p for UK cards. However, several platforms mark this up to 2.5-3.5%, pocketing the difference as revenue. For a landlord collecting £5,500 per month in rent across 5 properties, the difference between a 1.5% fee and a 3.5% fee is £110 per month — £1,320 per year in hidden charges. Some platforms like Latch use Open Banking for rent collection, which avoids card processing fees entirely.

2. Setup and Onboarding Fees (£100-£500)

Enterprise and agency-focused platforms frequently charge one-time setup fees for account configuration, data import, and onboarding sessions. Arthur Online, Goodlord, and similar platforms targeting letting agents often charge £200-500 for initial setup. Self-service platforms like Latch, Landlord Studio, and Hammock typically charge nothing for onboarding, as the setup process is designed to be completed independently.

3. Data Migration Charges (£200-£1,000)

Moving historical data from one platform to another can incur significant charges. Some platforms charge per-property migration fees of £20-50, meaning a 10-property portfolio migration costs £200-500. Others charge a flat migration fee of £500-1,000 regardless of portfolio size. This fee is rarely disclosed on pricing pages and only becomes apparent during the switching process. Free data export from your current platform is not guaranteed either — some providers charge for data exports, creating a double cost for switching. See our pricing models guide for more on switching costs.

4. Tenant Referencing Per-Check Fees (£15-£50)

Platforms that offer integrated tenant referencing typically charge per check rather than including it in the subscription. Costs range from £15 for a basic credit check to £50 for a comprehensive reference including employer verification, previous landlord reference, and Right to Rent check. A landlord turning over 3 tenancies per year could pay £45-150 annually in referencing fees alone, on top of the subscription price.

5. E-Signature Add-On Fees (£5-£15/month)

Digital document signing is increasingly essential for tenancy agreements, inventories, and compliance documents. Some platforms include basic e-signature capability but charge £5-15 per month for advanced features such as multiple signatories, audit trails, and template libraries. Others require a third-party integration like DocuSign (from £20/month), which adds both cost and complexity.

6. Premium Support Charges (£10-£30/month)

Standard support tiers on many platforms are limited to email with 48-72 hour response times or community forums. Phone support, live chat, and priority response times are frequently reserved for premium support tiers costing £10-30 per month. For landlords dealing with urgent tenant issues or compliance deadlines, waiting three days for an email response is not viable, making the premium support charge effectively mandatory.

7. Per-Unit Scaling Jumps at Thresholds

Some tiered platforms have hidden pricing thresholds where adding a single property triggers a jump to the next pricing tier. Adding a sixth property to a plan that covers five might increase the monthly cost from £15 to £30 — a 100% price increase for one additional property. These thresholds are not always clearly disclosed and can create unexpected cost increases when landlords acquire new properties.

8. Annual Price Increases (5-15%)

Most platforms reserve the right to increase subscription prices annually. Typical increases range from 5% to 15%. On a per-unit pricing model, these increases compound: a £6/unit rate increasing 10% annually becomes £6.60 in year two and £7.26 in year three. For a 10-property portfolio, that is an increase from £60/month to £72.60/month — an additional £151 per year by year three. Annual billing can sometimes lock in current rates for 12 months, providing a hedge against mid-year increases.

9. API and Integration Fees

Landlords who want to connect their property management software to accounting tools, bank feeds, or other services may face API access charges. Some platforms restrict API access to enterprise tiers (adding £20-50/month to the cost), while others charge per-integration fees of £5-10 per month per connected service. Latch includes Open Banking integration at no extra cost on paid plans.

10. Report Export and Data Download Fees

Generating reports for your accountant, mortgage broker, or HMRC should be a basic feature — but some platforms charge for report exports beyond a monthly limit, or restrict certain report types (P&L statements, rent roll summaries, tax reports) to higher pricing tiers. CSV and PDF export fees of £1-5 per report may seem trivial individually but accumulate over a tax year, particularly for landlords who need monthly reports for mortgage compliance.

11. Training and Webinar Costs

While most platforms offer basic documentation, live training sessions, personalised onboarding walkthroughs, and advanced feature webinars often carry charges of £50-200 per session. Enterprise platforms may require paid training for each new user added to the account. Self-service platforms with comprehensive help centres and video tutorials eliminate this cost entirely.

12. Contract Termination and Early Exit Fees

Annual contracts that offer discounted monthly rates may include early termination penalties equivalent to 3-6 months of subscription fees. A landlord on a £30/month annual plan who wants to cancel after 4 months could face a £90-180 exit fee. Monthly rolling contracts avoid this risk entirely, though they typically cost 15-20% more per month. Always check cancellation terms before committing to annual billing.

How to Calculate the True Monthly Cost

The following worked example shows how a platform advertising £12 per month actually costs £31 per month for a typical UK landlord with 5 properties collecting rent through the platform. This is based on real fee structures observed across multiple UK platforms in February 2026.

Which Platforms Have the Most Transparent Pricing?

We ranked platforms on pricing transparency by assessing: whether all fees are disclosed on the pricing page, whether the total cost at common portfolio sizes is calculable without contacting sales, and whether hidden fees exist beyond the advertised subscription price.

Checklist: Questions to Ask Before You Sign Up

Use this checklist before committing to any property management software subscription. Every question targets a common hidden fee that could increase your actual cost.

• Is the advertised price the total price, or are there per-property surcharges above a threshold?
• Is MTD for Income Tax included in the subscription, or is it an add-on or requires separate software?
• What is the payment processing fee if I collect rent through the platform? Is it the base Stripe/GoCardless rate or marked up?
• Is bank feed / Open Banking integration included, or is it an extra monthly charge?
• Can I export my data (CSV, PDF reports) at no additional cost? Are there limits on exports?
• Is there a setup, onboarding, or data migration fee?
• What support channels are included? Is phone or live chat support included or reserved for a premium tier?
• Are there early termination fees if I cancel an annual plan? What is the notice period?
• How much notice will I get before a price increase? Can I lock in the current rate with annual billing?
• If I add a user (partner, accountant), is there a per-user charge?
