About Us

Happy customers

“From start to finish, the communication and customer service provided by South West Oil Tanks was exceptional. Their clear advice on selection of a suitable replacement oil tank was greatly appreciated and the fact that my replacement tank was installed only two days after initial contact was outstanding”
Tim – Exeter

“Thank you for our oil tank installation in March 2019. Superb job. Very efficient and business like. Prompt. Helpful. Polite and friendly. Customer-focused, which is sadly not often the case in today’s world with many organisations.

Thoroughly well prepared, rebuilt the plinth from new, very focused on Regulatory requirements e.g. OFTEC, got the whole system up and running, even supplied us with a couple of hundred litres of oil to start us off again. Cleared away afterwards.

Extremely neat job. I wouldn’t have known they had been there, except for a gleaming brand new tank with all replacement plumbing. Finished well within their timescale. Would not hesitate to recommend them to anyone. 6 stars out of 5.”
John Vinton

“South West Oil Tanks did a fantastic job from start to finish. A fast, friendly and really helpful assessment and quote which was a competitive price, followed by quick and efficient booking of the job. Then on the day of the installation they were organised, clean and tidy and inspired real confidence. Good communication throughout too. I would 100% recommend them.”
