Customer Reviews
Fantastic service for my tank!
I needed a new Bunded Oil Tank and Certas Energy absolutely delivered! From browsing their selection to the actual installation, everything was seamless. The sales team helped me choose the right tank for my property, answering all my questions patiently. The installation crew was professional, tidy, and completed the job faster than I expected. I am so happy with the quality of the tank and the service provided. I will definitely be using them for my heating oil needs going forward and have already recommended them to my neighbour!
Road Diesel purchase, mostly positive
I bought 1000 litres of Road Diesel for my small business. The ordering process online was easy enough, and the price was competitive compared to other suppliers I checked. Delivery took about 5 days to reach my depot, which was within the estimated timeframe but still felt a bit slow when I was running low. The driver was helpful and positioned the truck well for the fill. My only minor gripe was that the online tracking update wasn't very detailed after the initial order confirmation; it would be good to have more frequent updates on the delivery progress. Overall, I got what I needed at a fair price.
Good Kerosene, delivery was quick
I ordered Kerosene for my home heating. The website was pretty straightforward to navigate, I found the product I needed quickly and placed the order. Delivery was surprisingly fast; it only took 3 days to reach my address in rural Scotland, which was impressive, especially given the current demand. The driver was polite and efficient. I haven't had to contact support, so I can't speak to that, but the oil itself seems to be of good quality, my boiler is running smoothly. Overall, a positive experience and I'd use them again for heating oil.
Quick AdBlue top-up
Needed AdBlue urgently. Placed an order online. Arrived in 2 days. Product was as expected. Good experience.
