Utility Warehouse Review (July 2026)
Overview
Utility Warehouse suits households wanting to bundle their bills, but long phone wait times and low official scores let down its energy service.
Who are Utility Warehouse?
Utility Warehouse is one of the UK's biggest domestic energy suppliers. The brand is owned by Telecom Plus PLC, a company set up in 1996 that originally ran from a pub in Henley-on-Thames before growing into a business listed on the London Stock Exchange. Utility Warehouse itself was started in North London to offer a wider range of household services.
What sets the supplier apart is its multiservice model, letting customers bundle gas and electricity with broadband, mobile SIMs, and home insurance. The company promises that the more services a customer takes, the more they save, with everything managed through one monthly bill and one app. It runs a word-of-mouth sales model using independent partners to sign up new customers, and offers a cashback card that takes money off the monthly utility bill. Eligible new customers who switch at least three qualifying services can receive up to £400 towards early exit fees from their previous providers.

Prices
These are the tariffs we have pricing for — the supplier may offer others.
The lowest-priced option currently offered by Utility Warehouse is the UW Fixed Saver 90, estimated at £1,671 annually. This plan locks in unit rates for 12 months and carries a £150 early exit penalty.
Households can also choose the UW Tracker Saver 2, a tracker tariff estimated at £1,683 per year. It has no fixed term but carries a £150 exit fee. The £150 cancellation charge on the fixed deal is also a flat total for dual-fuel customers who switch away before their term concludes.
Tariff details
This supplier's full tariff range
Utility Warehouse offers a range of standard variable, tracker, and fixed-rate energy deals, alongside specialist options for electric vehicle owners and homes with solar panels. The exact tariff a customer can get often depends on how many other services they bundle with their energy.
Customer reviews
Utility Warehouse maintains a Trustpilot score of 4.2 out of 5 across more than 79,000 reviews. The distribution skews positive, with 70% of users awarding five stars, compared to 14% who leave the minimum one-star rating.
Feedback indicates that users often highlight polite staff interactions and appreciate the convenience of consolidated billing. Conversely, negative reports frequently cite delays in reaching phone representatives and complications during smart meter installations.
During the most recent Which? annual energy survey, the firm achieved an overall score of 69. It earned 3 out of 5 stars for both customer service and value for money, alongside a maximum 10 out of 10 rating for its support of vulnerable households.
App experience
A dedicated mobile application is available to help users monitor their energy usage alongside other bundled accounts. It currently holds a 4.5 rating from 11,000 reviews on the Apple App Store, and a 4.2 score from over 11,000 Android users on the Google Play Store.
Both operating system versions receive regular software updates to maintain functionality. The Android iteration alone records more than 500,000 total downloads.
Recent user feedback suggests the interface is effective for tracking cashback card balances. However, a subset of reviewers note technical difficulties when attempting to top up prepayment meters or adjust their broadband settings.
Service and support
According to Citizens Advice, Utility Warehouse scores 2.45 out of 5, ranking 14th among assessed suppliers. Official data shows an average call centre wait time of 7 minutes and 16 seconds, with 40.5% of emails receiving a response within two days. The firm also records 38.1 complaints per 10,000 accounts.
The provider has registered formal vulnerability commitments with Citizens Advice to support at-risk households. Accepted payment methods include Direct Debit, cash, cheque, and prepayment meters.
Telephone support operates between 8:30am and 5pm on weekdays, and from 9am to 4:30pm on Saturdays. The contact centre remains closed on Sundays.
Utility Warehouse complaints and performance
In the most recent period available (Q4 2025), Utility Warehouse received 1,815 complaints for every 100,000 customers. The supplier resolved 83.14% of these complaints by the end of the next working day. It also sorted out 99.68% of complaints within eight weeks.
Green energy
Utility Warehouse's electricity fuel mix is largely fossil fuels, with some nuclear and other sources. The supplier does not currently offer a dedicated green energy tariff. It previously used certificates to match customer usage with renewable generation, but stopped buying these to help keep prices lower for its customers.
The company supports the UK government's target to reach net zero emissions by 2050. It encourages customers to lower their carbon footprint by offering smart meters and giving energy efficiency advice. It also supports the Smart Export Guarantee on its energy page, which pays customers who generate their own renewable electricity for any extra power they send back to the national grid.
Our verdict
Utility Warehouse suits households wanting to bundle their bills, but long phone wait times and low official scores let down its energy service.
Utility Warehouse provides an alternative to traditional energy suppliers by enabling households to consolidate gas, electricity, and other domestic bills. Although it maintains strong Trustpilot and app store ratings, its performance in official Citizens Advice metrics is weak, largely due to extended telephone wait times.
This model may suit consumers who prefer managing multiple utilities through a single portal and wish to utilise the associated cashback card. However, households that prioritise rapid phone support or swift email responses may find better service metrics elsewhere.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
