 Trustindex verifies that the original source of the review is Google. Brilliant service. We had needed an emergency supply of fuel, Sean responded really quickly and delivered next morning but found the tank had a blocked filter and fixed it on the spot. Heating all back up and running. Lifesaver.

 Trustindex verifies that the original source of the review is Google. A superb service from start to finish! Called back within an hour of my call. Visited next day and gave me a quote and timescale.  They kept to timescale and laid a new concrete base, supplied a new tank and took away the old tank. Sean explained everything and started the boiler for me.  I will  definitely use them again.

 Trustindex verifies that the original source of the review is Google. Really impressed with the service I received. Everything was clear, well explained, and competitively priced. The team were highly efficient and worked quickly to carry out the job to remove an old oil tank and relocate a new one a considerable distance from the house. All done with a friendly and positive approach. Would highly recommend

 Trustindex verifies that the original source of the review is Google. I experienced a leak in my oil tank and called S G Tanks who immediately visited site and offered me an acceptable quotation to replace the tank within days. They turned up on time and replaced the tank with speed and efficiency. I would highly recommend S G Tanks for their professionalism in a job well done.
