British drivers could be slapped with an extra £134 charge within days due to a simple tweak set to impact thousands across the UK. 

Ofgem’s updated energy price cap will see electricity prices rise by up to 10 percent from October 1 in a major blow for cash-strapped individuals. 

Those with an electric car will likely feel the sting with the price of topping-up a vehicle set to rise. 

According to calculations by digital car finance lender Carmoola, each charge will back road users an extra £1.29. 

The average price to top-up a car is around £13.41 but drivers should now expect to pay £14.70 to fully charge their batteries.

Aidan Rushby, founder and CEO of Carmoola, said the increase would be a “significant” rise and “impact” bills across the UK. 

He explained: "Ofgem’s price cap has a very real effect on the lives of households across the UK, especially as we approach winter and energy consumption rises. 

“While the effect on household energy costs for heating, lighting and cooking are understandably the main area of concern, the running costs of electric and hybrid vehicles will also have a marked effect on people’s energy bills.  

“As the 2030 ban on the sale of new petrol and diesel cars approaches, and more EVs hit UK roads, Brits will see their energy bills further influenced by their vehicles' charging needs. 

Over the course of a year, this will add up to an extra £134.16 in a major financial blow to those who have made the switch to electric machines. 

However, Aidan has warned road users can make some simple tweaks at home to reduce their usage and cut costs.

He added: “To save money, we’d suggest that EV drivers aim to charge their cars at home whenever possible, and explore whether their energy providers offer off-peak tariffs to help reduce charging costs by topping up at these cheaper times."
