How easy to use are Utility Warehouse’s website and app?
We weren’t able to rate Utility Warehouse for its website or app as not enough customers in our survey had used them. Octopus was the top supplier for its website, with 41% who said it was very easy to use, and its app, where 49% said using it was very easy.
Should I choose Utility Warehouse?
Utility Warehouse offers great value for money compared to other suppliers, according to its customers, has clear bills and resolves complaints speedily.
However, it receives a high number of complaints compared to the other suppliers in our survey. It’s important to be aware of that fact if you’re thinking of switching to Utility Warehouse.
And if you’re thinking of bundling other services with energy, it’s also important to work out how much you would pay by getting the other services elsewhere to determine whether you really will save money.
