Top currency exchange tips

Post Brexit, the pound reached its lowest level against the euro at 1.19 while against the dollar, it dipped to 1.31.

With the depreciation of sterling against major currencies, it means anyone travelling from the UK to mainland Europe or to the US has reduced spending power as the pound buys you less foreign exchange.

In addition to checking out the Asda Money rate sale, holidaymakers could consider prepaid currency cards, which allow you to pre-load currency on to the card and lock in the exchange rate on the day of the transaction, which could be good if the value of the pound spikes at a particular time.

Using your everyday debit or credit card abroad can be expensive – it can add between 3% and 10% on top of the cost of buying goods and service. See YourMoney.com’s Pick the right plastic for your summer holiday to save a packet to find the best cards for overseas spending.

One final tip: avoid airport bureaux at all costs as recent research revealed that some offer near parity rates for your pound. Being captive markets, airports tend to take a much higher margin for foreign currency, as this is the consumer’s only option. Even if the rate is just 2% higher, this could be as much as £40 on the average family’s holiday spending money.
