Good to do business with.
I have consistently found the roundsmen to be very helpful, businesslike and friendly. I have been with Certas for many years. The telephone staff are good too.

Failed to deliver quantity ordered (1400 litres) despite there being 9 inches to the top of the tank and previous deliveries had exceeded this level. Only delivered 1220 litres and my 2 complaints have not been dealt with.
Failed to deliver spent a week on the phone trying to resolve. Multiple calls no continuity of staff to resolve always had to start over with issue.
Quick and easy purchase
Great price and delivered earlier than expected.
Very efficient, and arrived on time.
Did the job, whilst I had popped out. Finished as I returned. No mess. Had a chat when being given ticket.
delivery was on the day given time .the driver was pleasant and made a quick delivery
Good prompt service
Web site easy to Navigate. Ordered without any problem. Prompt delivery!!
I would have given 5 stars but for the hugely inept AI opening part of the phone call. If AI doesn’t speed the way to the human, what’s the point in having it? I have managed to get through to a human within seconds for nearly 20 years with Total Butler/Certas energy without any help from AI. Maybe it’s time for a rethink or a rework. Sorry!
The sales lady was extremely efficient and the delivery was on time. I will be purchasing my next delivery from you.
Arrived on the day, very efficient and price competitive.
Certas has gone over to a new telephone answering service to put you through to the right person; unfortunately the process is interminable. totally focussed on the company’s benefit with no thought to the customer who has to say yes and no inanely. We are actually considering changing our supplier so dreadful is the experience. 👎
Helpful from start to finish ,prompt delivery
