Households might be left up to £ 1, 1000 a year worse off because of Brexit trade barriers, a report will recommend.
Global consultancy company Oliver Wyman will say that underneath the most negative scenario of high transfer tariffs and high regulatory obstacles the cost to the economy could overall £ 27bn.
Company profits for supermarkets and dining places could be wiped out because of supply string disruption.
A rise within costs would likely be passed on in order to consumers, the report will claim.
The analysis, to become published next week and seen by BBC, will make clear that also under the most favourable scenario associated with no tariffs and few regulating barriers, there are likely to be increased “red tape” costs.
It is going to suggest that increased paperwork and gaps for customs checks are likely to boost household costs by 1% annually, or £ 250 per home. The total cost to the economy will be £ 6. 8bn.
Economists who assistance Brexit said that reports of substantial economic costs post-Brexit were “alarmist” and that by focusing on the household economy, Britain outside the European Union can flourish.
The government has additionally made it clear that it wants the relationship with the EU that is since “frictionless” as possible when it comes to trade.
“While the outcomes of Brexit remain unclear, our analysis implies that any scenario will increase costs intended for UK households, ” said Duncan Brewer of Oliver Wyman, the consultancy firm that has done main pieces of work on the economic influence of Brexit for the financial services field and retailers.
They have also worked for the government.
“A Brexit deal that leads to no new tariffs with the EUROPEAN is still likely to increase the red tape expenses of imports, driving down income for businesses, and driving upward prices for consumers, ” Mister Brewer continued.
“Looking across the whole supply chain plus taking into account multiple different Brexit final results, one thing is clear: Brexit will reduce profits for consumer businesses.
“The only question is definitely by how much, which will depend on exactly what deal is negotiated.
“While businesses will do all they could to absorb rising costs, we anticipate they will be forced to gradually put up costs for shoppers. If they don’t, income could vanish. ”
The Oliver Wyman analysis discusses different sectors and the possible outcomes of Britain’s new relationship with all the EU.
It will claim that a supermarket chain with yearly takings of £ 10bn would certainly see profits fall by a 3rd under the most benign Brexit situation modelled.
Prices will have to rise by 2 . 3% to pay and ensure the business made as much revenue as it did pre-Brexit.
The report follows a number of research, including by government officials, that state there is likely to be a negative economic effect from Brexit .
The Bank of England has also said that the particular Brexit process has already cost families money .
Gerard Lyons, of the Economists for Brexit group, which supports Britain leaving behind the EU, said that although there may be a short-term “hit” from making the EU and the political procedure had not been “ideal”, the greater room with regard to manoeuvre for Britain once out from the union would have economic advantages.
“We need pro-growth insurance policies, and should remember that 90% of worldwide growth in the future will come from beyond your euro-area, ” said Mr Lyons, a former chief economist of Standard Chartered bank and now chief economic strategist for Netwealth.
He said: “Judgements like this [by Oliver Wyman] are much too pessimistic.
“Without the constraints that come from being truly a member of the EU, our economy can flourish. ”
