Block management software is a property management platform built specifically for residential managing agents, Right to Manage (RTM) companies and freeholders administering leasehold developments. It handles the operational tasks that generic property management tools cannot address properly - service charge allocation and accounting, Section 20 major works consultation, leaseholder portal access, compliance certificate tracking and RTM company administration. Unlike general property tools, block-specific software understands that each unit carries a distinct service charge percentage, that Section 20 consultation has legal time limits under the Landlord and Tenant Act 1985, and that RTM company directors have fiduciary duties requiring a proper audit trail. Off-the-shelf block management platforms charge between £10 and £20 per unit per month. Bespoke block management software built on Odoo costs from £12,000 one-time and scales across an unlimited leaseholder portfolio with no per-unit fee.
Block management software covers the operational and financial administration of leasehold residential buildings. For a managing agent or RTM company, that means:
Service charge accounting is the area where generic property management software consistently fails leasehold managing agents. The requirements are specific:
Demand notes must be issued at the correct times (usually bi-annually or quarterly per the lease terms), with a breakdown of estimated expenditure as required by Section 21 of the Landlord and Tenant Act 1985.
Apportionment must reflect each unit's lease-defined percentage - not necessarily an equal split across all units. A ground-floor flat may contribute a different proportion of lift maintenance costs than an upper floor flat, per the lease schedule.
Year-end reconciliation must produce a certified accounts statement showing actual versus budgeted expenditure, with the surplus credited to leaseholders or the deficit requested as a balancing charge.
Reserve fund must be held in a separate client account distinct from the service charge account, with interest credited to the fund and not to the managing agent.
Block management software automates all of this. When expenditure is posted, it is automatically apportioned across leaseholders per the lease percentages. Year-end accounts are generated from the system with the correct statutory format.
Section 20 of the Landlord and Tenant Act 1985 requires managing agents to consult leaseholders before committing to works or services that will cost any individual leaseholder more than £250. The consultation process has three stages, each with mandatory notice periods:
Missing these deadlines is not just a compliance failure - it can prevent the managing agent from recovering more than £250 per unit from leaseholders, regardless of actual expenditure. Block management software tracks every stage automatically, sends alerts before deadlines, logs all correspondence and maintains an audit trail if a leaseholder later challenges the process at the First-tier Tribunal.
Cost varies significantly based on whether you use a SaaS platform or a bespoke system:
SaaS block management platforms - per unit per month:
For a managing agent with 500 units under management, SaaS costs run between £60,000 and £150,000 per year in platform fees alone. As the portfolio grows, so does the monthly bill.
A bespoke implementation for a managing agent handling 200-500 units costs from £12,000 to £25,000 one-time. There is no per-unit monthly fee. A portfolio growing from 500 to 1,000 units incurs no additional licence cost. The break-even against SaaS typically occurs within the first 12-18 months for agencies managing more than 150 units.

General property management software (such as Arthur Online or Landlord Vision) is designed for landlords managing individual lettings - tenancy agreements, rent collection, maintenance requests per property. Block management software is designed for the leasehold sector - service charges, Section 20 consultation, reserve funds, RTM company administration and leaseholder portals. They have some overlap in maintenance management, but the service charge and compliance components of block management are sufficiently complex that specialist tools exist for that sector specifically.
Purpose-built block management platforms include Section 20 workflow tools that track each stage of the consultation process. They calculate the mandatory notice periods from the date of the Notice of Intention, alert the managing agent before deadlines, and generate pro-forma notices in the required format. Bespoke implementations can be tailored to your specific agency workflow, including integration with your document management system and automatic logging of all leaseholder correspondence against the consultation record.
Yes. The RICS Service Charge Accounting Technical Note specifies the format for annual service charge accounts. Block management software typically produces accounts in a compliant format. Bespoke implementations can be configured to match your preferred layout and to integrate with your external accountant's reconciliation process, reducing the year-end administration significantly.
Reserve fund accounting must be kept separate from the service charge account, with interest credited to the fund. Block management software maintains the reserve fund as a distinct account, allocates expenditure from it for major works items and produces a year-end reserve fund statement. Bespoke implementations can also model multi-year reserve fund projections against planned maintenance schedules, which is increasingly expected by leaseholders who want transparency on future major works funding.
Yes, when built with compliance designed in from discovery. Bespoke Odoo implementations map the data flows for leaseholder personal data, configure field-level access controls so sensitive data is visible only to authorised roles, and implement retention rules that anonymise or delete personal records at defined intervals. Subject access request handling is built into the admin interface so data protection officers can locate, export and delete personal data without requiring developer intervention.
Block management software is the operational foundation for any residential managing agent or RTM company handling more than a handful of leaseholder-managed blocks. The service charge accounting, Section 20 compliance and leaseholder portal capabilities are simply not achievable in generic property or accounting software. For agencies managing more than 150 units, bespoke software built on Odoo becomes economically rational within the first year - and the absence of a per-unit fee means the platform cost reduces as a proportion of revenue as your portfolio grows.
