Summary

• Set WhatsApp up on a business number your company owns, using the WhatsApp Business app for a small team or the WhatsApp Business Platform once several people or systems need to share the conversations.

• Get residents to opt in, keep formal notices and emergencies on other channels, and never put unrelated residents in a group chat.

• The step most teams skip is the audit trail: every WhatsApp conversation should end up on the resident's record in your property system, not on someone's phone.

Residents already live on WhatsApp. Ofcom found that 90% of UK online adults used WhatsApp in May 2025, and 74% used it every day. So the question for most property teams isn't whether to offer it. It's how to offer it without ending up with half your resident history sitting in a leasing manager's personal phone.

This guide covers the setup, the rules WhatsApp itself sets, and the part that matters when something goes wrong: keeping a record you can actually find.

How do I set up WhatsApp communication for tenants?

Start with a dedicated business number owned by the company, set up a WhatsApp Business profile on it, collect residents' opt-in, and connect the conversations to the system where you keep resident records. In order:

• Get a business number. One per building or one per portfolio, but never a member of staff's personal number. When that person leaves, the number and the history should stay with you.

• Set up the business profile. Add your logo, a short description, your website and opening hours so residents know they're talking to the operator, not an individual.

• Decide what the channel is for. Routine questions, viewing and contractor appointments, maintenance photos, reminders. Write it down and put it in the welcome pack.

• Collect opt-in. Ask at application or move-in, and record when and how the resident agreed.

• Set out-of-hours expectations. An away message that says when you'll reply, and where to go in an emergency.

• Connect it to your records. This is the step that protects you later, and it gets its own section below.

We compared WhatsApp against email, SMS and voice in our guide to tenant communication tools. This post goes deeper on doing WhatsApp properly.

Should we use the WhatsApp Business app or the WhatsApp Business Platform?

Use the Business app if one small team handles a handful of buildings. Move to the WhatsApp Business Platform once you need several people answering, automation, or conversations flowing into your property software.

The WhatsApp Business app gives you a business profile, labels to organise chats, quick replies, greeting and away messages, and the ability to link up to 10 devices and agents to one account. For a single site, that's often enough to start.

The limits show up as you grow. Unless the app is connected to your property system, the conversations stay in WhatsApp, so the history of a repair or a rent query ends up split between the chat and the resident's record.

The Platform is the route for that next stage, and it comes with its own rules. Under WhatsApp's Business Messaging Policy, you can only start a conversation using an approved message template, though you can reply freely within the 24-hour customer service window, which opens and resets each time the resident messages you. In practice, that means your rent reminders and building notices need to be set up as templates in advance.

Why does the audit trail matter for WhatsApp?

Because when a complaint, a dispute or a data request arrives, you have to produce what was said, and WhatsApp on a personal phone makes that hard or impossible.

Record-keeping is already where landlords get caught out. When the Housing Ombudsman reviewed its casework in its 2023 spotlight report on knowledge and information management, around two-thirds of upheld cases had issues with available data and information. That report looked at social landlords, but the lesson travels: if the record of a repair request isn't where the complaint handler can find it, the operator can't show what it did.

Data protection is the second reason. A resident can ask for the personal data you hold about them, and the ICO says you must respond without undue delay and at the latest within one month. Its guidance also says that if you have good reason to think staff hold the requester's information on personal devices, you should ask them to search their private emails, devices or instant messaging applications. Picture asking a leasing manager who left eight months ago to search their phone. A business number connected to your systems avoids that conversation entirely.

How do you keep an audit trail on WhatsApp?

Make sure every conversation lands on the resident's record in your system of record, owned by the company, with access controlled by role. The practical version:

• Own the number and the account. Company-owned, set up under a shared business email, with admin access held by more than one person.

• No personal phones. Write it into your communications policy. If staff use the Business app, it runs on company devices.

• Write it back to the property record. A maintenance request that arrives on WhatsApp should become a ticket against the unit. An agreed viewing should sit against the prospect. The chat is where the conversation happens; the PMS or CRM is where the record lives.

• Use roles and permissions. Leasing doesn't need to read every maintenance thread, and contractors shouldn't see resident conversations at all.

• Set a retention period. Decide how long you keep WhatsApp records, apply the same rule you use for email, and include it in your privacy notice.

• Plan for staff leaving. Removing someone's access should be one step in offboarding, and nothing they handled should leave with them.

Do tenants need to opt in to WhatsApp messages?

Yes. WhatsApp's own policy says you may only contact people who have given you their number and who have opted in to receive messages from you.

The Business Messaging Policy puts the responsibility on you to decide how you collect that opt-in and to comply with the law. It also says you must respect any request to stop, whether it's made on WhatsApp or anywhere else. A simple tick box in the application form, with a line explaining what you'll send, covers most operators. Keep the record of when each resident agreed.

Two habits to avoid. Don't add residents to a building-wide group chat, because it can expose residents' phone numbers to each other. Use one-to-one messages or broadcasts instead. And don't treat a resident who messages you once as having agreed to marketing.

What should and shouldn't go over WhatsApp?

Use WhatsApp for quick, everyday contact. Keep formal notices, legal correspondence and emergencies on channels designed for them.

• Good fit: maintenance requests with photos, appointment confirmations, parcel and access updates, viewing reminders, renewal nudges, general questions.

• Use another channel: tenancy agreements, formal notices and arrears letters, which should follow your legal advisers' guidance on how they're served.

• Never rely on it for: emergencies such as gas, flood or security. Give residents a phone line that's answered.

Which platforms offer WhatsApp integration for property teams?

There are two broad types: general business messaging tools and CRMs that add WhatsApp as a channel, and property platforms where WhatsApp is connected to resident and property records.

General tools are good at shared inboxes and marketing broadcasts. They aren't built around units, tenancies or maintenance, so unless they're connected to your property system, someone has to copy the outcome of each chat into the property system by hand. That copying is exactly where audit trails break.

When you're comparing options, ask four questions. Does a WhatsApp conversation create or update a record in our PMS? Can several people work the same inbox with their own permissions? Does it handle opt-outs automatically? Can we see the full history for one resident in one place?

What does this look like with Vinny?

Vinny is the AI teammate for property teams, and WhatsApp is one of the channels it works across, alongside voice, SMS, email and web chat. That matters for the records problem described above.

Vinny picks up enquiries across portals, your website and WhatsApp, and replies in under ten seconds on every channel. It connects to your PMS and CRM to read and act on live data, and writes updates back so your systems of record stay accurate and auditable. That covers the write-back step from the checklist above. Edge cases and high-risk situations are escalated to the right person automatically, and you set the controls for review, approval and intervention.

For outbound messages, resident campaigns let you describe what you want to send, and Vinny writes it once for WhatsApp, email and SMS. Opt-outs are enforced automatically the moment someone unsubscribes, and you can test a campaign before it goes. Reporting shows delivery and completion right down to the individual resident. For calls, Vinny answers day or night with voice AI.

On data, Vinny is ISO 27001, SOC 2, EU AI Act, and GDPR compliant, and your data is never used to train models.

If you want to see how WhatsApp, voice and your PMS fit together on your portfolio, book a demo.

WhatsApp is one channel among several, and the bigger shift is having an AI teammate answer across all of them. Our guide to what an AI leasing assistant is and how it works explains the rest.

Frequently asked questions

Can I use my personal WhatsApp to message tenants?

You can, but you shouldn't. The history leaves with the phone, residents get your personal number, and you may have to search that phone if a resident makes a data request. Use a company-owned business number instead.

Is WhatsApp GDPR compliant for tenant communication?

WhatsApp can be part of a compliant setup, but compliance depends on how you use it: a lawful basis and opt-in, a privacy notice that mentions it, a retention period, and records held where you can find and export them. Avoid group chats that expose residents' numbers to each other.

How do I message tenants on WhatsApp outside the 24-hour window?

On the WhatsApp Business Platform, you start a new conversation with an approved message template. Once the resident replies, you can respond freely for the next 24 hours.

Should formal notices be sent by WhatsApp?

No. Keep tenancy agreements, formal notices and arrears letters on the channels your legal advisers recommend, and use WhatsApp to tell residents something formal is on its way.
