Oil Tank Replacement in Dorchester, Dorset – Bunded Oil Tank Installation
11/03/2026
Total Energy Services recently completed an oil tank replacement in Dorchester, Dorset, installing a new bunded Deso oil storage tank at a rural property outside the town.
Many homes in and around Dorchester rely on oil-fired central heating, particularly in villages where mains gas is not available. Over time, oil tanks can deteriorate due to age, weather exposure, and UV damage, making replacement the safest and most reliable solution.
Our team regularly carries out oil tank installations and replacements across Dorset, helping homeowners upgrade to modern, environmentally protected fuel storage systems.
Replacing an Ageing Oil Tank in Dorchester
The property’s original oil tank had been in place for many years and was beginning to show signs of wear. Older tanks can become vulnerable to cracking, leaks, or structural weakness.
Oil tank replacement is often recommended when:
-
The tank is over 20–25 years old
-
Cracks or bulging appear in the tank walls
-
The tank no longer meets environmental safety standards
-
The tank is not bunded and located in a risk area
To ensure safe oil storage for the property, the homeowner opted for a modern bunded oil tank upgrade.
Installation of a New Deso Bunded Oil Tank
Our engineers removed the old tank and installed a new Deso bunded oil tank, which provides a high level of protection against leaks and environmental contamination.
Bunded tanks are designed with an inner tank surrounded by an outer protective layer, meaning any oil that escapes the inner tank is safely contained within the outer bund.
During the Dorchester installation, our team carried out:
-
Safe removal and disposal of the old oil tank
-
Preparation of the tank base and installation area
-
Installation of the new Deso bunded oil tank
-
Connection of the oil supply pipework
-
Full compliance and safety checks
The new tank now provides secure and compliant fuel storage for the home’s oil heating system.
