2.2

Certas Energy UK Limited has many reviewers reporting missed or repeatedly delayed oil deliveries, with some left without heating or hot water and told different reasons for non-delivery. One reviewer says a boiler service missed carbon monoxide and left their elderly father's boiler in a poor state. Several reviewers report long waits on the phone, unanswered emails and no callbacks. One reviewer says a delivery went ahead on the date given, using a small vehicle as asked, and a few others describe helpful, friendly drivers and good service. One reviewer describes being charged more than expected by direct debit despite being in credit, and another reports high fuel card prices.

Do not use this company. They wanted to increase our DD by nearly 300% even though we were almost £600 in credit. We called and told them we wanted to keep it as it was, but the following month they took £160 more than they should have. We have now asked for all of our money back, (last Tuesday,) and are still waiting for it. Funny how they can take it instantly but can't refund it in the same way. They probably do this to thousands of customers earning them a fortune.

Shocking customer service. Order date extended without me being told, delivery day missed, delivery apparently now unable to be completed due to lorry hose too short. No replies to my telephone calls x3. Now have to wait 7 days for refund. My advice, avoid at all costs

AVOID THIS COMPANY! We approached Certas Energy as our usual fuel supplier was unable to let us know when they would next be able to deliver due to the situation with the war in Iran. When we contacted Certas Energy, we were assured by the sales team that we would have a fuel delivery by the 23rd March. We received a notification to say that our fuel would be delivered on Saturday 14th March. We waited all day and then we received a delivery POD to say the driver ran out of time! We assumed that they would re deliver on the next working day, how wrong were we! We spent the next week chasing them for a new delivery date, they eventually confirmed that we would receive our delivery on Saturday 21st March. We then received a delivery POD at 8.50am to say non delivery as they couldn't find the address! We called Certas at 10am to ask why the driver did not call to say he couldn't find the address and that we needed the oil delivery today as our tank is really low. They said we can't re deliver today as the fuel has been off loaded from the truck! THIS IS AN ABSOLUTE JOKE!! We have now cancelled our order and will source elsewhere from someone more reliable
