Brexit is either an opportunity for the UK to reboot itself as an exciting trading nation or one of the greatest mistakes in the history of British democracy.

There is scarcely an aspect of British life which will not be changed in some way by the vote to leave the European Union.

Of course, there are profound economic ramifications which remain difficult to predict in the face of so many unknown factors.

But in January, a leaked Government report said Brexit will leave UK "worse off in every scenario".

On Tuesday, Brexit secretary David Davis said Britain will not be "plunged into a Mad Max-style world borrowed from dystopian fiction" after it leaves the EU. He also claims fears about a "race to the bottom" in workers' rights and environmental standards are "based on nothing" and that continued close co-operation between the UK and the EU on regulations and standards will help ensure "frictionless" trade.

Here are 11 possible ways in which Brexit could change your world.

1. Cheese prices could rocket

Cheddar imports could be hit with giant tariffs

Instead of munching on cheese and crackers, Britain could go plain crackers if we leave the EU without a trade deal.

The UK would face tariffs of 45.5% on Italian mozzarella and 44.1% on Irish cheddar under a no-deal scenario, according to the British Retail Consortium . The entire cost of a Sunday roast could spiral with a 39.6% tariff on British beef if the UK had to rely on World Trade Organisation rules.

Not everyone sees a food price disaster on the horizon. JD Wetherspoon chairman Tim Martin is much more upbeat about Brexit, arguing that prices “will actually be lower on leaving the EU without a deal in March 2019” if the UK choses to abandon tariffs. Brexiteers look forward to a future in which farmers in Argentina and the US compete to sell exports at the best prices to the UK.

However, there are also fears that delays at customs checks could lead to food rotting and restrictions on EU citizens coming to the UK could result in a shortage of farmworkers.

2. Your neighbour’s vacuum cleaner could get a lot louder

Sales of vacuum cleaners which use more than 900 watts and make more than 80 decibels of noise are banned in the EU. It would be up to a post-Brexit Government to decide if it wanted to legislate to allow vacuum cleaners that are as loud as a Harley Davidson going at full pelt.

The European Environment Bureau (EEB) has argued it is a “misconception” to think that the more powerful your appliance, the cleaner your house will be – but eurosceptics have held up the vacuum ban as a prime example of Brussels meddling.

3. Your passport and your driver’s licence will change

The days of the burgundy passport could be numbered

If you were born in 1988 you won’t remember a time when passports weren’t burgundy. But the dark blue design could make a comeback once we are out of the EU and the gold-lettered “European Union” at the top of the passport will certainly vanish.

You can also expect the EU flag to disappear from your driving licence when it’s time to renew it. These are cosmetic changes but politicians will be in a hurry to provide millions of Brexit supporters with incontrovertible evidence that the country is truly out of the EU.

4. The cost of using your phone abroad could soar

For years, one of the nastiest aspects of coming home from holiday was realising just how much you had been billed for sending photo-messages back home or calling your mum.

Last year roaming charges were banned across the EU. You can make calls, send texts and surf the internet for the same cost as if you were back in Wales.

It’s possible that the UK – or your mobile phone provider – will be able to negotiate just as good a deal. But the era of it costing as much to send a photo of a spectacular ice cream as it did to buy the highly stacked cone could be about to return.

5. There might be a longer queue at your local sandwich shop

Pret A Manger sounded the alarm about its dependence on workers from outside the UK

The hospitality industry has major worries about how Brexit will affect recruitment. Last year Pret a Manger’s director of human resources estimated that only “one in 50 people who apply to our company to work is British”.

6. You may need a new form of health insurance when you next go on holiday

Brits have got used to travelling with a European Health Insurance Card (EHIC) in their wallets. It has guaranteed you the same level of healthcare as a national of the EU country you are visiting.

It also applies in non-EU countries including Norway and Iceland (which are part of the European Economic Area, a grouping the UK is not expected to join) and Switzerland.

There will be dismay if a new arrangement isn’t agreed and the cost of travel insurance shoots up. People didn’t think they would end up spending more to go bungee-jumping when they voted for Brexit.

The Nuffield Trust has raised concerns about the potential strain on the NHS if people who have retired abroad now look to get medical treatment back in the UK.

It warned: “If all the British pensioners who currently receive health care in other countries through EU agreements had to return, caring for them would require the NHS to spend an extra £1bn a year. This is twice as much as we pay for them to receive care abroad, and there would also be a need for extra beds equivalent to two new hospitals.”

7. The flow of medicines could be interrupted and a shortage of nurses is feared

The Welsh Government's New Treatments Fund aims to speed up access to life-changing drugs

The £60bn pharmaceutical sector could take a blow if the UK is no longer able to have drugs approved for use in the EU through the European Medicines Agency. This would be bad news for the economy but doctors and patients alike will be angry if bureaucratic hold-ups prevent medicines coming onto the market in time to save lives.

There are also worries about the supply of health workers. In November it was reported that the number of nurses and midwives coming to work in the UK from Europe has crashed by 89% since the referendum.

8. Expect battles about your rights in the workplace

All employees across the EU are guaranteed a basic set of rights under the Working Time Directive. You are supposed to work no more than an average 48 hours a week unless you opt-out, have at least four weeks paid leave a year, and you are guaranteed 11 consecutive hours of rest in a 24-hour period.

It’s highly unlikely that a party that wanted to win an election would suggest scrapping outright all the provisions laid out in the directive but the TUC is worried of a watering down of rights. It warns of the dangers of “longer working hours, fewer paid holidays and an extreme Brexit forced on us all by a small group of hardliners”.

There are plenty of areas where rights could be rolled back with the goal of cutting red tape and boosting competitiveness. The European Court of Justice ruled that journeys to and from work by mobile workers count as working time; it also ruled that an on-call doctor is officially working even if he or she is asleep if they are required to be on site.

9. You could face a dilemma: Eat Welsh lamb and support local farmers or buy cheaper imports

Will the Welsh lamb industry face a crisis as a result of free trade deals?

Agriculture is one of the most controversial aspects of Brexit. A free trade deal with New Zealand might sound like a great idea to economists but Welsh farmers fear that the market could be flooded with cheap lamb imports.

Farms that depend on support through the EU’s Common Agricultural Policy face an uncertain future. Will the UK Government provide subsidies or will each devolved nation have its own system?

And will there also be different animal health standards in Scotland, Wales, England and Northern Ireland? The Welsh Government wants to see common frameworks but it is adamant these should be negotiated between the different nations and not imposed by Whitehall.

10. You can expect to hear lots of rows about funding for Wales

Billions of pounds of EU cash has been pumped into Wales in successive efforts to revive the economy but an intense debate has started as to what support will be available once the UK leaves the EU.

Proposals for a “shared prosperity fund” open to the entire UK have aroused suspicion in Cardiff Bay. The Welsh Government does not want to have to bid for cash from a Whitehall pot and has warned that “any attempt to claw back the money for regional investment and run it as a UK government programme would fundamentally undermine the UK government’s promise to respect devolution”.

However, the likes of Aberconwy Conservative MP Guto Bebb have argued that a brand new approach is needed because EU funding has been a “failure in a Welsh context”.

11. If your son or daughter hopes to work in finance, he or she may have to spend a lot of time in the EU

Cities such as Frankfurt will want to grab a slice of Britain's banking action

Some of the biggest names in banking are moving jobs to the continent and Lloyd’s of London is opening a European subsidiary so it won’t lose business.

It would be ironic if Brexit means that anyone who joins a banking graduate programme will be more likely to spend time working in the EU.
