Maintenance Management: Arthur vs ZenRent
Maintenance management is Arthur Online's strongest feature. Their contractor marketplace connects landlords with vetted tradespeople, and the repair request workflow — from tenant report to job completion — is well-designed.
ZenRent also tracks maintenance requests and costs, but without a built-in contractor marketplace. However, ZenRent logs all maintenance expenses against specific properties for tax purposes, and compliance alerts prevent you from missing certificate renewals that Arthur handles through manual tracking.
Pricing: ZenRent vs Arthur Online
Arthur Online charges per unit per month, starting from around £12/unit/month for smaller portfolios. For a 5-property landlord, this could cost £60+/month compared to ZenRent Standard at £9.99/month for up to 5 properties.
ZenRent pricing
- Essential (free): Up to 1 property, basic income/expense tracking, compliance alerts
- Standard (£9.99/month): Up to 5 properties, MTD submissions, Open Banking, WhatsApp integration
