Team Flitwick

At Certas Energy, we're totally dedicated to meeting all your needs. Delivering heating oil to your home, farm or business, when you need it. Installing and maintaining tanks and boilers. And providing extra services like our popular fuel cards. We're the UK's number 1 heating oil supplier for a reason. We provide top-quality products to help heat your home — like Glowmax, our premium heating oil which helps protect and improve the efficiency of your heating system. Our friendly team are on hand to help wherever you are in the UK; from when you place your order, right through to delivery. Plus, our network of drivers will ensure your heating oil is delivered safely and efficiently — even checking for leaks by giving your tank a free visual inspection before they top up.
