Some consumers have expressed concern about security company ADT's decision to introduce a fuel surcharge.

Eyewitness News has learnt ADT will charge its clients an additional R7.50 from 1 May.

The security company says the surcharge is aimed at mitigating the impact of ongoing fuel hikes on its operating costs.

ADT’s decision to introduce a fuel surcharge was communicated to clients last week, hot on the heels of the latest fuel hikes of 71 cents a litre inland, and 66 cents in coastal regions.

However, the announcement is not sitting well with some consumers.

In an online forum on the issue, one person says ADT just e-tagged themselves in the foot.

ADT has told Eyewitness News it will comment on the issue on Tuesday.

Meanwhile, Spence Mouton of Cape Town-based security company SMA says they are trying to keep petrol expenditure to a minimum.

“We are trying to see where we can save on fuel,” he says.

Mouton says the ADT’s fuel surcharges is a first and he has not heard of any companies following suit.
