Samsung Galaxy Alpha also helps bump electronics revenue up 20.9% in September.
The iPhone 6 has helped the UK reach a three-year-high for consumer electronics spending followings its release in September.
The iPhone 6 and the iPhone 6 Plus have become Apple’s fastest selling phones to date, shifting over 10 million units within the first three days.
According to research from Barclaycard, the phone’s release caused a jump of 20.9% in consumer electronics spending in September. This is a large boost compared to an average increase of 4.5% for the first six months of the year.
Samsung’s September release, the Galaxy Alpha, also helped increase spending. The phone was unveiled alongside the Galaxy Note 4, and was quietly released to high street at the start of September.
Barclaycard’s research said that September’s electronics spending accounted for a third of all consumer spending in that month.
Managing director of Barclaycard, Chris Wood, said: "The fall in inflation to a five-year low undoubtedly helped ease the pressure on households last month, while one of the driest and warmest Septembers on record encouraged them to part with more of their money.
"While consumers continue to shop for value, and remain cautious overall about the future, we could finally be seeing the start of a sustained recovery in consumer spending."
