Utility Warehouse Energy Review 2026: Is UW Worth It?

Last updated: 29 October 2026

Is Utility Warehouse a good energy supplier? It can be good value if you take broadband, mobile or insurance from it too: its cheapest fixed energy deals need at least two other UW services, and its fixed tariffs charge £75 per fuel to leave early, when we checked on 29 October 2026. On service, Which? gives Utility Warehouse (UW) a 69% total score, and Citizens Advice ranks it 13th of 16 suppliers for April to June 2026. This SwitchSquid review covers how UW’s bundle pricing works, how it compares with Octopus Energy and British Gas, what Which?, Citizens Advice and Trustpilot say, and how to check whether UW beats the price cap for your home.

Utility Warehouse energy review: the short verdict

• Best for: households that already want UW broadband, mobile or insurance, and higher energy users. MoneySavingExpert says UW’s fix is a better bet for higher users than lower users, because the energy saving has to cover the cost of the extra services.

• Price: UW says its variable tariff is always below the price cap when you take more than one service, and its tracker is reviewed quarterly and kept below the cap. Its fixed tariffs run for up to 12 months and the discount grows with each service you add.

• Exit fees: £75 per fuel on UW fixed tariffs, so £150 for dual fuel. The variable tariff has no exit fee.

• Service: middling. Which? scores UW 69% overall and placed it 10th of 17 energy companies on its customer score. Citizens Advice gives it 2.63 out of 5. UW’s Trustpilot page showed 4.1 from 85,926 reviews on 29 October 2026.

• Look elsewhere if: you only want energy, or the UW broadband and mobile plans would cost you more than the deals you have now.

How Utility Warehouse energy pricing works

UW sells energy, broadband, mobile and insurance on one bill, and its best energy prices depend on how many of those services you take. It says it has 1.4 million customers and more than 80,000 UK-wide Partners, who are usually customers paid to sign up others. When we checked on 29 October 2026, UW’s energy page listed four tariff types:

• Fixed: rates locked for up to 12 months. A smart meter is required, an exit fee applies if you leave early, and the discount gets bigger as you add services.

• Tracker: reviewed every quarter and kept below the price cap, with a discount that grows with every service you add. UW lists an exit fee and a smart meter requirement.

• Variable: moves with the price cap, with no exit fees. UW says you will always pay less than the cap when you take more than one service.

• EV: a variable tariff with cheaper electricity between midnight and 5am, for customers with a smart meter and an eligible electric vehicle.

MoneySavingExpert’s review, updated on 26 August 2026, explains the fixed range in more detail. “Fixed Saver” needs at least two other services from broadband, mobile and insurance, “Fixed” needs at least one, and “Fixed Start” needs none. Two mobile SIMs count as two services. MSE also warns that UW’s broadband contract is 18 months while the energy fix is 12, so you could be tied to the broadband for six months longer than the energy.

UW also offers a prepaid card that can earn up to 10% back off your bill when you spend on it. It is free for three months and then £3 a month, so it only pays off if you spend enough with the retailers it covers. UW’s page also promotes up to £400 towards early termination fees from your old providers and a Price Pledge: if you do not save in your first year, it says it will pay you double the difference and let you leave without exit fees. Which? notes that this pledge applies to customers who take three or more services and use the card.

Utility Warehouse vs Octopus vs British Gas

The table compares UW with Octopus Energy, which people often compare it with, and British Gas. Ratings are as shown on each source on 29 October 2026.

Sources: Which? energy company survey results, Citizens Advice supplier ratings, Trustpilot and Octopus Energy tariffs. Which? scores combine a September to October 2025 customer survey with its own assessment of company practices. Trustpilot lists UW under “Internet provider” because its reviews cover all UW services, not only energy.

Which is better, Octopus Energy or Utility Warehouse?

On independent service scores, Octopus is ahead. Which? named Octopus a Recommended Provider for 2026 with a 74% total score, against 69% for UW, and Citizens Advice ranks Octopus 5th and UW 13th for April to June 2026. Octopus’s tariff page lists Flexible Octopus, a variable tariff with no exit fees whose prices change every three months, Fixed Octopus for 12 or 18 months, a daily tracker and several smart tariffs, none of which need you to buy other services.

On price, the answer depends on your household. MoneySavingExpert said on 26 August 2026 that UW’s fix substantially undercut other energy fixes on offer at that time, but only if you also take one or two other UW services. If you would buy UW broadband or mobile anyway, or you use a lot of gas and electricity, UW can come out ahead. If you only want energy, Octopus or another supplier’s fix is usually the simpler comparison. Our Octopus Energy supplier guide has its tariffs in more detail.

What does Martin Lewis say about Utility Warehouse?

The most recent MoneySavingExpert article on UW energy, written by MSE assistant editor Clare Casalis and updated on 26 August 2026, says plainly that it does not mean MSE or Martin Lewis recommend Utility Warehouse or network marketing. MSE says it has always had reservations about UW because it is commonly sold through Partners, but that UW’s fixed deal undercut other fixes at the time, so it explained how the deal works. Its advice is to work out the total cost of energy plus the extra services you would need, and to check you are not tied into broadband or mobile contracts with high exit fees.

Is Utility Warehouse a good energy supplier?

It is an average performer on service with a strong price for the right household. Which?’s review of 16 June 2026 gives UW three stars for overall customer service, value for money and clarity of statements, and two stars for customer communications. It scored full marks (10 out of 10) for help for customers who need it, but 6 out of 15 for complaints. Which? also notes UW does not offer a dedicated live chat option, although it has a WhatsApp service.

Citizens Advice gives UW 2.63 out of 5 for April to June 2026, with 2.4 for contact waiting time and 2.5 for complaints. The UW reviews on Trustpilot are kinder, at 4.1 out of 5 from 85,926 reviews, but they cover broadband, mobile and insurance as well as energy.

Is Utility Warehouse under investigation?

Ofgem concluded an investigation into Utility Warehouse on 10 November 2021. According to Ofgem’s press release of that date, UW failed to treat some customers in debt fairly between 2013 and 2019 and agreed to pay £1.5 million into Ofgem’s voluntary redress fund. Ofgem said UW had accepted its failings and put measures in place to stop them happening again. For any newer action, Ofgem publishes enforcement news on its own website.

How to check whether UW beats the price cap for you

1. Find your rates. Take your unit rates and standing charges for gas and electricity from your latest bill.

2. Find your usage. Your yearly kWh for each fuel is on your bill or in your supplier’s app.

3. Work out a yearly cost. Multiply your kWh by each unit rate and add 365 days of standing charge.

4. Compare with the cap. From 1 October to 31 December 2026 the cap averages 26.32p per kWh and 54.83p a day for electricity, and 7.97p per kWh and 29.68p a day for gas, on Direct Debit (Ofgem).

5. Add the bundle. Add what you would pay UW for broadband, mobile or insurance, and take off what you pay for those services now.

6. Get fixed quotes elsewhere on the same usage and compare total yearly cost, including any exit fees.

Ofgem will announce the price cap for 1 January to 31 March 2027 by 25 November 2026, and UW’s own energy page says further price increases are anticipated in January. See our next price cap announcement guide for the dates.

Switching to or away from Utility Warehouse

• Joining UW: UW says it contacts your old supplier for you and your energy goes live within two to five working days.

• Leaving a UW fix: the exit fee is £75 per fuel. Citizens Advice says you can switch away from a fixed deal without an exit fee in its last 49 days, so check your end date first. Our switch without an exit fee guide explains how.

• Your other UW services: leaving UW energy may change the price of your UW broadband, mobile or insurance, so ask UW what would change before you switch.

• Already thinking of leaving? Our Utility Warehouse alternatives guide compares the options in more detail.

Fit summary

• UW suits you if: you want energy, broadband and mobile on one bill, the UW services you would add are fairly priced for you, and you use a lot of energy.

• Octopus or another supplier suits you if: you only want energy, you value service scores, or you want a variable tariff with no exit fees and no bundle.

• Wait before switching if: you are partway through another fix and the exit fee would wipe out the saving.

Important conditions

• UW tariff details, exit fees and offers are from UW’s own pages when we checked on 29 October 2026 and can change.

• UW’s claims about savings and being cheapest are its own; compare a quote for your home before you agree.

• Price cap figures are Ofgem averages for England, Scotland and Wales on Direct Debit; your region, meter and payment method change your rates.

• According to GOV.UK on 28 October 2026, the Chancellor will ask Ofgem to remove standing charges from household gas bills in 2027 or as soon as possible after. Until then, gas standing charges stay on every tariff that has one.

• Comparison results depend on your postcode, meter and usage, and not every supplier or tariff is listed on every comparison site.

FAQ

Do you have to take other services to get UW’s best energy price?

Yes, for the cheapest fixes. MoneySavingExpert says the “Fixed Saver” tariff needs at least two other services from broadband, mobile and insurance and “Fixed” needs at least one, while “Fixed Start” needs none. You must keep the extra services for the life of the fix.

What does Which? say about Utility Warehouse?

Which? gives UW a total score of 69%, made up of a 72% customer score and a 65% assessment score. It is not a Which? Recommended Provider for 2026. UW scored 10 out of 10 for help for customers who need it but 6 out of 15 for complaints.

Octopus scores higher on service: 74% from Which?, where it is a Recommended Provider, and 3.67 out of 5 from Citizens Advice, against 69% and 2.63 for UW. UW can be cheaper for households that also take its broadband, mobile or insurance, especially higher energy users.

What does Martin Lewis say about Utility Warehouse?

MoneySavingExpert’s article of 26 August 2026 says it does not mean MSE or Martin Lewis recommend Utility Warehouse or network marketing. It explains that UW’s fix undercut other fixes at that time, but only with extra UW services, so you need to compare the total cost.

Is Utility Warehouse under investigation?

Ofgem concluded an investigation into UW on 10 November 2021, after UW agreed to pay £1.5 million into Ofgem’s voluntary redress fund for failing to treat some customers in debt fairly between 2013 and 2019. Ofgem publishes any newer enforcement news on its website.

How long does it take to switch to Utility Warehouse?

UW says your energy goes live within two to five working days, and that it contacts your old supplier for you. Leave your old Direct Debit in place until your final bill is paid, UW advises.

Final decision card

Utility Warehouse is a fair choice if you want several home services on one bill and the extra services are priced well for you: its cheapest fixes need two other UW services, and leaving a fix early costs £75 per fuel. On service it sits mid-table, with 69% from Which? and 2.63 out of 5 from Citizens Advice. If you only want energy, compare fixed and variable deals from other suppliers on your own usage before you decide.
