Trading Standards are responsible for this, but I doubt you have been shortchanged - the below is from a thread from a while ago;

I wouldn't place too much credence upon level measurement - aside from giving you and indication of when you need to reorder.

Firstly, any tank be it metal or plastic has 'creep' designed into it. In essence, the tank is designed to expand slightly when it is full of fuel as obviously the strains and stresses are very different to when it is empty. As the level falls, the distortion will be less; when the level of fuel is higher, it will be greater. Its a pretty complex and non-linear relationship and varies according to a raft of factors - such as the batch of material the tank is made from; the make of tank; the model of tank, the density of the stored fuel etc.

Secondly, yup - the tank expands with heat and contracts with cold. Its designed to do precisely that. Hence, the reason why first generation plastic tanks were calibrated on the outside, until tank manufactuers were on the receiving calls from irate oil distributors whose customers were accusing them of under delivering. The reality of course was that the deliveries were fine - its just the calibrations were far from accurate.

If you genuinely feel aggrieved, then report them to the local Trading Standards office, but be ready to provide proof.

Welcome to the forum.

Contact the local Trading Standards office. If they are convinced you are correct, they may 'set a trap' on your next delivery.

Also by reporting your suspicions it may add to any case file they have of similar reports; if others have complained they might 'set a trap' with someone elese.
