Steer clear of this company!! Rude and incompetent customer service. I have been overcharged on bills for quite some time now and UW are very reluctant to refund despite proof of false readings and involvement from the ombudsman. I used to have 2 meters in my property. 1 dual rate (general electric use) and 1 single rate (specifically for storage heaters). However, for over a year despite numerous complaints my single rate is still being charged for dual rate tariff. After involving the energy ombudsman, I was promised any overcharges would be refunded and an engineer would visit my property to remove the meter (as the heaters which it was once used for were no longer in use). In June after some cancellations by the UW engineer the meter was finally removed. Yet, UW are now claiming no record of this despite UW organising the meter removal in the first place. In the end it was a Scottish Power engineer (who was brought in by UW) that removed the meter. I waited months for a UW engineer appointment only to be told the UW engineer was unable to complete the job and required assistance from SP. I was then told after the removal that the national database would be updated and any over charges would be refunded by August at the latest. It's now August (over a year later since the original complaint) and I'm still paying a dual rate tariff for a meter that was only a single rate meter...and that has been removed from my home months ago. Being a single parent keeping up with these unnecessary payments and threats of late charges has caused me great anxiety. Despite a year of complaints and involvement of the energy ombudsman I am still overpaying for this non existant dual rate meter. UW say i now have to wait over another month (18th September) to yet again get one of their useless engineers out to confirm that the meter they themselves had arranged to be removed months ago... has in fact now been removed. After that they say they will review again and refund all the years over payments for both being charged at a dual rate tariff before removal and any charges after the meters removal... but i wont hold my breath. Wish I had never come across UW.
