Customer Reviews
Good for fuel, not solar
Needed commercial solar, but Certas Energy doesn't offer it, though FuelTapp ordering was easy.
Good savings on AdBlue!
The coupon code made my AdBlue purchase much better, though finding where to apply it online was a slight faff.
Tank Telemetry works well
tank telemetry's been solid, got good info, prices were fair for sure.
Easy peasy ordering for Gas Oil
Has anyone else found Certas Energy super simple to order from online? I was looking for Gas Oil (Red Diesel) and their website was really straightforward. I even had a quick question about minimum order values and the chat support was helpful. Got my delivery super fast too, which was great.
Great value, especially with CarbonTrace
I was checking out CarbonTrace and the pricing was pretty good. I was wondering if they offer any specific discounts for larger orders or if there's a coupon code I missed. Do they have fuel cards available too?
Decent service for fuel tanks, with one small snag
hey everyone, was wondering if certas energy does fuel tank hire, or if you have to buy outright? i was browsing their fuel storage tanks and needed one for a project. ended up getting a 2500-liter bunded tank, and the ordering process was pretty straightforward online, though i did try a coupon code that didn't apply to this specific product, which was a bit annoying. delivery was on time, driver was sound. product quality seems good, feels sturdy. my only minor gripe was the coupon not working, but overall, a solid experience.
So happy with my Certas Energy order!
got 27% off my HVO Renewable Diesel (off-road) order thanks to a coupon code! i was looking for solutions for my agricultural business and Certas Energy really came through. the representative i spoke with was super helpful and walked me through the process of even getting HVO & Diesel Fuel Tank Hire. the whole experience was so easy, definitely recommending them to all my contacts in the sector. will absolutely be shopping here again for future needs!
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.
