The verdict in three sentences
For a housing association with 14,000 homes in Dublin, a complete tenant portal costs EUR 60,000 to 120,000 excl. VAT in 2026, including about EUR 15,000 for the housing ERP connector. The realistic target is a 30 % drop in contact centre calls, provided the portal genuinely handles the three dominant call reasons: rent, repairs and documents. WCAG 2.1 AA accessibility is not optional for a body delivering a public service mission, and it must be budgeted from the scoping phase.
The features that reduce calls, and their cost
At a housing provider, three reasons usually account for 65 to 75 % of inbound calls: rent balance and payment, faults and repair requests, document requests. The portal must absorb them first.
| Module | Scope | 2026 budget (EUR excl. VAT) |
|---|---|---|
| Tenant account and login | Account creation by tenancy reference, two-factor authentication, authorised representatives | 6,000 to 12,000 |
| Rent payment | Card, direct debit, online arrears repayment plan | 7,000 to 14,000 |
| Repair requests with photos | Guided triage, photos, time slot, dispatch to contractor | 10,000 to 22,000 |
| Complaint tracking | Real-time status, history, SMS notification | 6,000 to 12,000 |
| Online documents | Rent statements, rent certificates, receipts, service charge reconciliation | 5,000 to 10,000 |
| WCAG 2.1 AA accessibility | Accessible design, external audit, accessibility statement | 6,000 to 15,000 |
| Mobile app (PWA) and notifications | Installable on smartphone, light offline mode | 5,000 to 20,000 |
| Housing ERP connector | Sync of tenancies, rent accounting, repairs | 15,000 |
| Total | Delivery in 6 to 9 months | 60,000 to 120,000 |
The ERP connector conditions everything else: without reliable sync of rent accounts and work orders, the portal shows wrong balances and generates more calls than it removes.
Accessibility: what to require
A large share of tenants are older, living with a disability or not comfortable with digital tools. WCAG 2.1 AA, referenced by the EU Web Accessibility Directive and EN 301 549, sets precise criteria, and public bodies must publish an accessibility statement. In France, the equivalent RGAA framework carries fines of up to EUR 50,000.
| Requirement | What it implies | Budget impact |
|---|---|---|
| Contrast and text size | Adapted design, 200 % zoom without loss | Low if planned at mock-up stage |
| Keyboard navigation | All forms usable without a mouse | Medium |
| Screen readers | Labels, photo alternatives, explicit error messages | Medium |
| Plain language | Simple wording, accessible reading level | Low |
| External audit | 50 success criteria checked on a page sample | EUR 3,000 to 6,000 |
| Statement and multi-year plan | Mandatory publication, 3-year action plan | EUR 500 to 1,500 |
What a 30 % drop in calls is worth
| Indicator | Before portal | After 12 months (estimate) |
|---|---|---|
| Inbound calls per year | 70,000 | 49,000 |
| Average call length | 6 minutes | 6 minutes |
| Contact centre hours | 7,000 h | 4,900 h |
| Tenants active on the portal | 0 % | 40 to 55 % |
| Rent paid online | 8 % | 25 to 35 % |
| Average time to handle a repair | 6 days | 3 days |
Mini case study
Siobhan, CIO of a housing association in Dublin, receives 70,000 calls a year. A 30 % drop removes 21,000 calls, i.e. 2,100 agent hours. At EUR 32 loaded cost per hour, that is EUR 67,200 a year, plus about EUR 8,000 saved on printing and postage for paperless rent statements. For a EUR 95,000 project with EUR 14,000 of annual maintenance, net savings reach EUR 61,200 a year: the portal pays back in about 19 months.

FAQ
How long does rollout take?
Allow 6 to 9 months, including 6 to 8 weeks for the ERP connector. A phased launch by area office or estate limits risk and lets you measure the drop in calls.
How do we get less digitally connected tenants to adopt it?
Providers reaching 50 % adoption combine a very simple journey, an installable PWA and in-person support. Plan EUR 5,000 to 10,000 for communication and digital inclusion support in year one.
Does online payment increase arrears?
No, it tends to reduce them. Online repayment plans and SMS reminders before due dates cut late payments by 10 to 20 % based on observed feedback.
Must data be hosted in the EU?
It is strongly recommended, with a GDPR-compliant host and, where possible, certified infrastructure for sensitive data. The extra cost is limited, around 10 to 20 %.
What maintenance budget should we plan?
Plan 12 to 18 % of the initial cost per year, i.e. EUR 10,000 to 20,000, for updates, security and ongoing accessibility compliance.
