What records should you keep for an oil tank installation or replacement?

Fixed tanks matter at sale

Oil heating is common off the gas grid. Buyers want proof the tank is compliant, supported, and not leaking.

What to keep

Installation certificate and line tests: where carried out.

Base and bunding photos: showing containment for spills.

Warranty and inspection: including any replacement of feed lines.

Delivery access notes: if tank location affects refill.

Document any decommissioning of an old tank if it was replaced.
