There are two main reasons that we ask specific questions every time you call about an order. The first reason is to comply with GDPR Information Security and protect customers’ personal data.  We have a legal obligation to protect our customers’ personal data from misuse, exploitation, loss or theft. One of the ways we do this is by always asking you to answer two security questions each time you call about an order, a delivery, or anything else that involves sharing your personal information. The second reason is that we sell controlled oils which are given a rebated rate of duty. That is why we are part of the Registered Dealer in Controlled Oils (RDCO) scheme with the HMRC, which aims to tackle fuel fraud.  As part of that scheme, when you place an order with us we are legally obliged to ask certain questions to ensure legitimate usage. This includes asking what you will use the kerosene for, or checking details of any non-domestic accounts you hold, as well as verifying standard contact and address details.
