Can I Keep My Home Phone With Utility Warehouse Full Fibre?
Yes, many households can keep their existing home phone number when switching to Utility Warehouse full fibre. However, you need to check how your landline will connect and arrange any number transfer before your old service ends.
The Utility Warehouse digital switchover can raise questions for households that still rely on a traditional landline. Will you lose your number? Can you keep your current handset? Do you need a new phone?
The good news is that full fibre broadband and home phone services don’t have to come from the same provider.
With a separate digital landline service such as Phonely, you can use Utility Warehouse for broadband while keeping a familiar home phone setup.
This guide explains how to keep your number, what equipment you may need and what to check before switching.
What is Utility Warehouse?
Utility Warehouse is a UK provider that bundles everyday services such as energy, broadband and mobile. Many people are drawn to Utility Warehouse because of its all-in-one approach and competitive pricing when services are combined.
When it comes to broadband, Utility Warehouse offers both part-fibre and full fibre options, depending on availability in your area. Utility Warehouse full fibre usually refers to FTTP, or fibre-to-the-premises. This means fibre runs directly into your home rather than relying on older copper phone lines.

Here is where things change for landlines.
Traditional landlines rely on the old copper phone network. Full fibre broadband does not use this network at all, so a standard landline cannot run over Utility Warehouse fibre.
Utility Warehouse offers full fibre broadband packages that don’t require a traditional landline. If you want to keep a home phone, check whether your chosen package includes a suitable phone service or whether you’ll need a separate digital landline provider such as Phonely.
Why VoIP is the solution for landlines on Utility Warehouse Fibre
VoIP stands for Voice over Internet Protocol. In simple terms, it lets you make and receive phone calls using your internet connection instead of a copper phone line.
With full fibre, VoIP is the standard way landlines now work. Calls travel over your broadband connection rather than the old phone network. This is the same change happening across the UK as the traditional phone network is switched off.

Most people worry that VoIP sounds complicated. In reality, it is often simpler than older phone setups. Once installed, you use your home phone just as you always have.
Can I Keep My Number With Utility Warehouse Full Fibre?
Yes, you can usually keep your existing landline number when moving to Utility Warehouse full fibre, provided your number is eligible for transfer and you arrange the switch correctly.
This process is called number porting. It allows you to move your existing telephone number to another provider without changing the number your friends, family or other contacts use.
If you’re planning to use Utility Warehouse for broadband and Phonely for your home phone, follow these steps:
- Check your current landline service. Find out who provides your existing phone line and whether it’s included in your broadband package.
- Confirm your new broadband arrangements. Ask Utility Warehouse when your full fibre service will become active and whether the change will affect your existing phone line.
- Request your number transfer. Visit Phonely’s number transfer page and check whether your existing landline number can move to Phonely.
- Agree on the switching arrangements. Make sure the broadband installation and phone number transfer are coordinated, particularly if both services currently come from the same provider.
- Set up your digital landline. Once your new service is ready, connect your compatible handset using the equipment provided and test incoming and outgoing calls.
Important: Don’t cancel your existing landline independently before checking the transfer arrangements. Ending the old service too early can complicate the process.
According to Ofcom’s landline switching guidance, customers can generally request to keep their number even after cancellation, provided they ask within one month. However, arranging the transfer beforehand is the safest approach.
What Equipment Do I Need to Keep My Home Phone?
Switching to full fibre doesn’t automatically mean buying a new telephone.
Many households can continue using their existing corded or cordless home phone with a compatible VoIP adapter, also known as an analogue telephone adapter (ATA).
The adapter connects your traditional handset to your broadband router, allowing calls to travel over your internet connection rather than the old copper phone network.
A typical setup includes:
- A working broadband connection: Your Utility Warehouse full fibre service provides the internet connection.
- A compatible VoIP adapter: This allows many existing home phones to work with a digital landline service.
- Your existing handset: You may be able to keep the telephone you’re already comfortable using.
You can find more information in Phonely’s adapter setup instructions.
Remember that digital landlines depend on electricity and broadband. If your household relies on the phone during emergencies, ask your provider about suitable backup arrangements before switching.

What Should I Ask Utility Warehouse Before Switching?
Before changing your broadband or home phone service, ask Utility Warehouse these questions:
- Will my chosen full fibre package include a home phone service, or will I need a separate provider?
- Will installing full fibre automatically disconnect my existing landline?
- Can I keep my current phone number if I use a separate digital landline provider?
- When will my existing phone service stop working?
- Will switching affect any other services in my current broadband package?
- Are there any early termination charges I should know about?
It’s also worth checking whether your current home phone connects to any personal alarms, telecare devices or other equipment that needs a telephone line.
The most important thing is to understand what happens to your existing number before agreeing to a switching date.
