The UK economy is on course for an even deeper slowdown as consumer spending and business investment take a hit from uncertainty surrounding the Brexit negotiations, new research has found.
Britain’s gross domestic product (GDP) is expected to drop from 1.8% growth last year to 1.5% in 2017 and to 1.4% in 2018, according to PwC’s UK Economic Outlook.
The professional services firm has downgraded its previous prediction for 2017 when it pencilled in GDP to ease at a slower pace to 1.6%.
Consumer spending has been a key driver of the UK economy, but household spending power has come under increased pressure from a double-whammy blow of higher inflation and sluggish wage growth.
John Hawksworth, PwC’s chief economist, said Brexit uncertainty would also apply the brake to business investment as firms put their capital expenditure plans on pause.
He said: "Brexit-related uncertainty may hold back business investment, but this should be partly offset by planned rises in public investment.
"Fiscal policy could also be further relaxed in the 2017 Autumn Budget to offset the ongoing real squeeze on household spending power."
UK economic growth for the first quarter was confirmed at 0.2% last month, a marked slowdown compared with the 0.7% expansion seen in the final three months of 2016.
The pay squeeze on British households has also intensified, with wage growth continuing to lag behind inflation.
Once the cost of living is taken into account, annual total pay in real terms sank by 0.7% to its lowest level since the summer of 2014 and fell 0.5% excluding bonuses over the three months to May, according to the Office for National Statistics (ONS).
Inflation marched to its highest level in nearly four years at 2.9% in May, with the Bank of England expecting inflation to peak at 3% by the autumn.
Economists are widely expecting GDP to struggle in the second quarter of 2017, and predict momentum in the UK economy to slow in the years ahead.
The influential EY ITEM Club nudged down its GDP growth outlook from 1.8% to just 1.5% in 2017, saying that the UK economy has deteriorated since April.
Forecasts by the Centre for Economics and Business Research (Cebr) show that the UK economy will grow by just 1.3% in 2017, a substantial downward revision from an earlier forecast of 1.7%.
Despite the pessimistic outlook, Mr Hawksworth said the UK economy was not edging towards a recession.
He added: "There are still downside risks relating to Brexit, but there are also upside possibilities if negotiations go smoothly and the recent Eurozone economic recovery continues.
"We expect the UK to suffer a moderate slowdown, not a recession, but businesses should be monitoring this and making contingency plans."
PwC also flagged a potential a growth fall in the UK property market, with house price inflation expected to hit 3.7% for this year, down from 7% in 2016.
It would mean the average British home would be worth £220,000 by the end of 2017, a jump of £8,000 on last year, as prices push towards the £300,000 bracket by 2025.
Richard Snook, senior economist at PwC, said: "There is a huge disparity in how sub-regional housing markets have performed since the recession.
"The local authorities that have experienced the greatest falls in house prices since 2007 are all based in Northern Ireland, while London dominates biggest risers with all boroughs experiencing price growth of over 50%."
A Treasury spokesman said: "The fundamentals of the UK economy are strong and more people have a job than ever before.
"Our National Living Wage has given the lowest earners a pay rise and we’ve cut taxes for millions of hard-working people.
"The Government is working to deliver the best possible Brexit deal that works for Britain."
