Does Utility Warehouse use Openreach?
NETWORK INFRASTRUCTURE EXPLAINED
THE SHORT ANSWER
Yes. Utility Warehouse is currently listed by Openreach as a service provider on its network, and it also appears on Openreach’s current FTTP and FTTC provider lists. That means UW does use Openreach for broadband services. If you are considering signing up with them, you might want to check out our Utility Warehouse broadband review to see how they perform overall.
But that is only part of the story. UW’s own recent broadband material says it also partners with CityFibre, and CityFibre’s current broadband provider list includes Utility Warehouse as well.
WHAT OPENREACH IS, AND WHY THIS MATTERS
Openreach is the wholesale network business that builds and maintains a large part of the UK’s fixed broadband and phone infrastructure, including copper phone lines and full fibre. Consumers do not normally buy directly from Openreach. Instead, Openreach supplies retail providers, and Openreach’s own service provider page tells customers to contact the provider that sends the bill.
That distinction matters here. When people ask whether Utility Warehouse "uses Openreach", what they usually mean is whether UW broadband runs over Openreach’s physical network. According to Openreach’s current provider listings, the answer is yes.
FULL FIBRE AND STANDARD FIBRE PRODUCTS
On Openreach’s current Full Fibre, FTTP providers page, Utility Warehouse is listed as a provider. On Openreach’s FTTC providers page, Utility Warehouse is also listed. That is strong current evidence that UW uses Openreach both for full fibre in some areas and for FTTC or VDSL style services in others.
Openreach’s broader service provider page separately lists Utility Warehouse as a provider on the Openreach network. So this is not just a historical reference or a one off mention on an older product page. It appears across Openreach’s current provider listings.
DOES UTILITY WAREHOUSE ONLY USE OPENREACH?
No. The current official evidence shows that Utility Warehouse also sells broadband over CityFibre. UW said in a 2025 press release that it partners with CityFibre, and CityFibre’s own current provider list includes Utility Warehouse.
UW’s own help material makes the split especially clear. Its CityFibre six months free full fibre promotion says the offer is only available in areas provisioned by CityFibre’s network and is not available on Openreach connections. That wording only makes sense because UW has customers and offers that can sit on either network, depending on the address and product.
| NETWORK PARTNER | SERVICE TYPE | AVAILABILITY |
|---|---|---|
| Openreach | FTTC & Full Fibre (FTTP) | Nationwide footprint |
| CityFibre | Full Fibre only | Specific urban areas |
The most accurate answer is this: Utility Warehouse uses Openreach, but not exclusively. In some postcodes, a UW broadband order can be delivered over Openreach. In others, UW can provide service over CityFibre. That is why a blanket yes or no answer on its own is incomplete.
If you are trying to work out what will happen at a specific property, the deciding factor is local network availability. UW’s own fibre guide says not all full fibre providers cover every area, and CityFibre tells customers to check whether its network is available at their address before choosing a provider.
WHAT THIS MEANS FOR YOUR CONNECTION
Two people can both buy broadband from Utility Warehouse and still be connected over different underlying networks. One customer may be on an Openreach service, while another may be on CityFibre. The retail brand is the same, but the access network in the background can differ. That conclusion follows directly from UW appearing on both Openreach and CityFibre provider lists, and from UW’s own CityFibre specific help article.
This can affect the type of installation, the equipment already present at the property, and who turns up to do the network work. CityFibre says its engineers complete broadband installations on behalf of the broadband provider, while the provider manages service enquiries and appointments.
UW’s own support content also shows that some customers are dealing with Openreach linked infrastructure. For example, UW says that if phone line damage is outside your property, it is the responsibility of BT Openreach. That is consistent with UW still supporting services that rely on Openreach infrastructure.
HOW TO TELL WHICH NETWORK YOU ARE ON
The clearest clue is whether your service is being sold or installed as a CityFibre product. UW’s CityFibre promotion explicitly says it is only for addresses provisioned by CityFibre and not for Openreach connections. So if UW has told you the order is on CityFibre, or if CityFibre is arranging the installation, you are not on Openreach for that product.
If none of that applies, and your UW service is a standard Openreach type product such as FTTC or Openreach FTTP, then Openreach is likely to be the access network. Openreach’s current FTTC and FTTP provider pages show that both kinds of service are sold by Utility Warehouse.
WHY THE CONFUSION EXISTS
A lot of broadband brands in the UK are not network owners. They are customer facing providers that buy access from wholesale network operators. Openreach is one such network operator, and CityFibre is another. Because consumers deal with the retail brand, not the underlying network owner, it is easy to assume a provider uses only one network when it may actually use several.
Openreach tells customers to contact the provider that sends the bill, and CityFibre says customers contract with the broadband provider rather than with CityFibre itself. That is exactly why the right answer for Utility Warehouse needs a bit of nuance. The correct answer is not simply "UW uses Openreach" or "UW uses CityFibre". The correct answer is that UW uses Openreach in part of its footprint and CityFibre in part of its footprint.
DOES THIS MATTER FOR SPEED OR RELIABILITY?
It can matter, but mostly because the access technology can differ by network and address. Openreach’s listings show Utility Warehouse on both FTTC and FTTP, while CityFibre is a full fibre network and markets full fibre services through partner providers. So the actual service available to you depends on what UW can supply at your property, not just on the fact that the bill says Utility Warehouse.
That means the better question for a specific home is not only "Does Utility Warehouse use Openreach?" but "Which network will UW use at my address?" The second question is the one that determines installation method and the type of broadband you can order.

FINAL VERDICT
Yes, Utility Warehouse does use Openreach. Openreach currently lists Utility Warehouse on its general network provider page and on its FTTP and FTTC provider lists. But Utility Warehouse is not an Openreach only provider, because UW also currently partners with CityFibre and appears on CityFibre’s provider list. For a specific customer, the underlying network depends on the property, the available infrastructure and the product being sold at that address.
