Core Telecom: Improving tenant communication

In this article, Core Telecom looks at how 03 numbers can transform communication in social housing by offering a consistent, cost-effective contact point for tenants and teams

Good communication is essential in social housing. Whether it’s tenants reporting repairs or teams working across locations, a clear, consistent phone number can make a big difference.

That’s why more housing associations and social landlords are switching to 03 numbers—and Core Telecom is making them available completely free to the sector.

What makes 03 numbers different?

Unlike local numbers (like 020 or 0113), 03 numbers aren’t tied to a specific region. They offer a national presence with local-rate call costs, making them ideal for providers serving multiple areas or moving to hybrid ways of working.

Why switch?

One number, wherever you operate

Give tenants a single, reliable point of contact—regardless of where your offices are based.

Affordable for tenants

Calls to 03 numbers cost the same as 01/02 numbers and are included in most mobile and landline bundles.

No disruption when you move

Your number stays the same through relocations, restructures, or service changes.

Better call handling

Our 03 numbers include routing, voicemail-to-email, IVR menus, and call analytics—making it easier to manage enquiries efficiently.

A professional image

An 03 number shows you’re accessible, forward-thinking, and built to serve across regions.

Free for housing providers

We offer UK housing providers:

• No setup fees
• No monthly charges
• No hidden costs

It’s our way of supporting better communication in the sector.

Already use 03 numbers?

If you already have 03 Numbers, we will host them 100% free of charge, again removing all costs.

You can port them seamlessly to our network, no downtime or disruption.

Get started

Switching is quick and straightforward. We handle the setup and support—so you can stay focused on your tenants.

Let Core Telecom help your housing association save on telecommunication costs so you can allocate more resources to your primary mission of providing secure and affordable housing.
