Every property is different, so our written quotation will outline precisely what you need, with no hidden charges.

The Process

Although replacing your oil tank is a job for the experts, we know how to make things simple. Ensuring that all OFTEC regulations are closely followed, existing oil is safely transferred to a holding tank to be replaced or cleaned.

If necessary, the base of the tank will be repaired, along with the removal of any rusty or damaged pipework. A robust new tank, along with any necessary filters, isolation valves, pipes etc will be installed, in line with regulations. New or cleaned oil is then pumped back into your replacement tank, with a full checking process along the way and upon completion. We’ll also safely remove your old tank and then clear up before we leave.

We aim to leave your property the way we found it – with the exception of the addition of a new, safe, secure oil tank, of course!


After we install your oil storage tank, we’ll ask you to sign a job sheet to make sure that you’re satisfied with our installation. We’ll send you a safety certificate and a maintenance pack for your peace of mind. OFTEC and the Council will be contacted on your behalf, too.

Quality is our watchword and we are looking forward to hearing from you. Contact us to find out more.
