According to a report by the British Chambers of Commerce, Brexit has not perturbed UK customers, with the economic slowdown this year being less severe than first feared.
However, the latest economic forecasts suggested that increased inflation would affect household budgets.
The resilience against the Brexit vote among businesses and customers has been widely acknowledged by economists and experts.
In December, the BCC said the 1.8% growth the UK economy made in 2016 would slow to 1.1% in 2017. However, they have now revised their estimations, predicted that the UK economy will expand by 1.4%.
They have estimated that 2018 will fall to 1.3%, with 2019 at 1.5%.
Previously, Europe’s largest management consultancy advised businesses not to invest in Britain due to the uncertainty of Brexit.
Article 50 is likely to be triggered by the end of this month.
Adam Marshall, BCC director general, said: “Thanks to the hard work of businesses and the continued resilience of the redoubtable British consumer, the UK economy is likely to grow somewhat more strongly than we’d previously expected during 2017."
“Yet with several years of unspectacular growth ahead, coupled with inflationary pressures and the uncertain outcome of Brexit negotiations, it has never been more important to tackle the longstanding constraints that limit business confidence and growth here at home.”
“More thoughtful and radical moves to improve the business environment would give businesses – and GDP forecasts – a boost during a critical and complex time.”
This isn’t the first time the UK economy’s strength has surprised analysts and experts by growing more than expected. Last year it was reported that Brexit Britain was defying expectations.
