Property Management Owner Portal with Online AGM Voting: London 2026

The verdict in three sentences

The portal bundled with block management software covers the basics, but rarely matches what London leaseholders expect after years of banking apps. A custom owner portal linked to your management system brings documents, service charge accounts, repairs and online AGM voting into one place, and removes a large share of calls and emails from property managers. The budget depends mainly on the number of integrations and how demanding the voting module is, so plan for 4 to 6 months and scope it carefully.

What regulation requires, what leaseholders expect

In England, leaseholders and Right to Manage or residents' management companies have statutory rights to service charge summaries, supporting documents and consultation under Section 20 of the Landlord and Tenant Act 1985. The Building Safety Act 2022 adds information duties for higher-risk buildings, and the RICS Service Charge Residential Management Code sets expectations on transparency. Company law allows electronic meetings and voting for RTM and RMC companies when the articles permit. Many firms rely on the module of their software, which is often clunky.

For a firm managing 320 developments, about 11,000 units, that clunkiness costs money. Each property manager looks after 40 to 50 blocks and receives dozens of emails a day asking for minutes, a statement or an update on a leak.

Features and budget

The project splits into modules. The core links the portal to your block management software by API or scheduled export: units, leaseholders, accounts, documents. Then come the document vault, the finance module (demands, statements, Direct Debit or card payment), the repairs module and the AGM module.

Online voting is the most demanding module: strong voter identification, voting weights per resolution as defined in the articles (one vote per unit or by share), proxy handling, time-stamping and automatically generated minutes. It can rely on a certified voting provider embedded in the portal.

For comparison, white-label owner portals on the UK market charge, as a 2026 order of magnitude, 0.40 to 1.20 GBP per unit per month, which is 4,400 to 13,200 GBP a month for 11,000 units, without deep customisation. Custom work needs an upfront investment but removes the per-unit fee.

Security and compliance

The portal handles personal and financial data: hosting in the UK or the EU, encrypted documents, two-factor authentication for directors of the residents' company, and access logs, all in line with UK GDPR. Permissions are granular: a leaseholder sees their own units and the shared documents of their block, directors also see contracts and invoices, the property manager sees the whole portfolio. Kolonell can add a cybersecurity audit to the project.

Mini case study

Sophie, managing director of a block management firm in London (320 developments, 8 property managers), logs 1,200 calls and emails a month on documents or accounts, at 8 minutes each, or 160 hours. A 25 % drop frees 40 hours a month, about 1,600 GBP at 40 GBP an hour loaded, or 19,200 GBP a year. On top of that, dropping a per-unit portal fee of 0.60 GBP saves 6,600 GBP a month. For a complex project around 12,000,000 FCFA (18,290 EUR), payback is counted in months.

FAQ

Is online AGM voting legally valid?

Yes, for RTM and RMC companies whose articles allow electronic meetings and voting, provided voters are identified and secrecy is respected where required. The portal produces time-stamped minutes within 5 minutes of the vote closing.

Can the portal connect to our current block management software?

In most cases yes, by API or a scheduled export every hour. If the software is closed, a specific connector is priced on quote, with 3 to 6 weeks of work.

How long until launch?

A document-focused core can go live in 8 to 10 weeks. The full version with voting takes 4 to 6 months, rolled out in waves of 20 to 30 blocks.

Will older leaseholders use it?

Adoption often passes 60 % within 12 months if login works through an emailed magic link and managers demo the tool at the AGM. Paper remains available for others.

Where is the data hosted?

With a UK or EU host, daily backups and retention aligned with legal periods, for example 6 years for accounting records.
