The verdict in three sentences
A tenant repairs portal for a London housing association with 24,000 homes costs GBP 70,000 to 140,000 as a 2026 order of magnitude, over 5 to 7 months, plus ongoing support of GBP 1,700 to 3,500 per month. The investment is justified by a 25% drop in contact centre calls and full traceability of contractor jobs, which matters more than ever under the Social Housing Regulation Act and Awaab's Law. Success depends on the housing management system connector and WCAG 2.2 AA accessibility, both to be locked down in the specification.
The tenant journey and what it requires technically
The head of customer experience starts from a simple fact: a leak under a sink generates three calls on average, one to report it and two to ask when the plumber will come. The portal removes the last two by making progress visible.
| Journey step | Function | Technical requirement |
|---|---|---|
| Sign-in | Tenancy reference or GOV.UK One Login style account | Matching against tenancy records in the housing system |
| Reporting | Guided choice of room and item, photo, available time slots | Repair triage tree of 60 to 120 reasons |
| Triage | Tenant, landlord or service contract responsibility, damp and mould flag | Rules from the repairs policy and Awaab's Law timescales |
| Assignment | Job sent to the responsive repairs contractor | API or dedicated contractor portal |
| Tracking | Timestamped statuses, appointment, SMS or email updates | Webhooks and message queue |
| Closure | Tenant sign-off, satisfaction score, after photo | Tenant Satisfaction Measures and contractor KPIs |
| Installable app | Home screen access on the phone | Progressive web app with light offline mode |
The triage tree is often underestimated. A wrong reason sends a locksmith for a boiler fault. Plan 15 to 20 days of workshops with customer advisers and housing officers to build it.

At Kolonell, a portal connected to a housing management system is priced on quote after a two to three week discovery, because the connector cost depends heavily on the vendor and the installed version.
Points of attention specific to social housing
Accessibility is a baseline. Many housing associations fall under the public sector accessibility regulations, and in some estates more than 30% of tenants are over 60. A phone route and a route assisted by the housing officer remain essential.
Data governance matters too. Photos taken inside homes may show people or documents. The portal must restrict access to the people handling the job, with a retention period recorded under UK GDPR.
Finally, current repairs contracts often set how data is exchanged with contractors. If the contractor has no API, a simple contractor portal where the operative updates the status from a phone costs less than a full connector.

Hannah, head of customer experience at a London housing association, runs a contact centre handling 180,000 calls a year, 55% of them about repairs. The full cost of a handled call is estimated at GBP 3.90.
With a GBP 105,000 portal, a 25% drop in calls means 45,000 calls avoided, worth GBP 175,500 a year. After deducting GBP 31,000 of annual support, the net gain reaches GBP 144,500. The project pays back in about 8.7 months after go-live, before counting fewer wasted contractor visits.
FAQ
How long does the housing system connector take?
Usually 4 to 8 weeks of development depending on whether the vendor offers a documented API or file exchanges. The connector represents GBP 13,000 to 30,000 of the budget.
Do we need a native mobile app?
Rarely. An installable web app covers 90% of use cases, photos included, for 30 to 40% less than separate iOS and Android apps.
Does the portal have to meet WCAG?
For landlords covered by public sector accessibility rules, yes, with a published accessibility statement. An initial audit costs roughly GBP 4,500 to 9,000.
What adoption rate should we target in year one?
A realistic goal is 30 to 45% of repair requests submitted through the portal after 12 months, backed by estate communications and rent statement inserts.
Can we start with a smaller scope?
Yes, a first phase limited to communal areas and three repair categories lets you test the triage tree for 3 months before opening it to all homes.
