I would not even rate this company one star. 6 months ago l was offered by Avro a smart meter. I had it installed thinking l would not need to give meter reading anymore, wrong, they are not set up to take readings from smart meters. It was fitted, l had to get an electrician out as my sockets didnt work anymore, then British gas out to repair the condensation pipe on my boiler which the fitter damaged. Total disaster. I have been trying for months to speak to Avro regarding this, as since it was fitted my readings are far higher than the old meters. Considering there are only 2 of us in the property and we spend a lot of time away. If you phone you get 'sorry we cannot take your call" if you email you don't get an answer. I have now cancelled my direct debit and gone with the biggest supplier, l am happy to pay a bit more to the new supplier knowing l can speak to an advisor. All l can say is do not use Avro, theg are happy to take your money, but don't care about customer service.
