“The top 100 EU regulations cost the UK economy £33.3 billion per year.” (Leave)
“As a member of the European Union, our companies can sell, without barriers, to a market of 500 million people. The Single Market means that exporters only need to abide by one set of European regulations, instead of 28 national ones.” (Remain)
A lot of EU regulation isn’t linked to the single market but involves issues such as the environment.
So trading off the benefits of the single market against the costs of all regulations would be a misleading exercise.
With that caveat in mind, neither of these claims is wholly convincing.
The claim about the cost of the biggest EU regulations is taken from a paper by the think tank Open Europe, which is flawed in a number of respects.
Costs of regulations are calculated from uncertain predictions
Regulations have only been reviewed systematically by the Regulatory Policy Committee, which checks their quality, since 2012.
In general, few estimates of impact are carried out once the regulations in question are actually in place.
For example, the paper claims, on the basis of the impact assessment done before it came in, that the Working Time Directive costs the UK £4.2 billion a year. There has been no evidence since the impact assessment was carried out to support this figure.
A much more recent review by the Department for Business, Innovation and Skills (which produced the original estimate) found that the Directive had had few, if any, negative impacts on the UK labour market.
Regulations also have benefits that can be set against costs
The £33.3 billion figure is simply a total of projected costs. Yet some regulations produce benefits as well.
As Open Europe notes, the projected benefits for the “top five costliest EU-derived regulations” outweighed the costs.
The paper ignores these for the purposes of its figure on the basis that they may not have materialised, although this applies to costs as well.
Some regulations that now come from the EU would be necessary even if we left
It’s also the case that, if we weren’t members of the EU, we would still need some similar rules.
According to UK in a Changing Europe Fellows Damian Chalmers and Jonathan Portes, since the British government has signed up to the Basel III rules, we would need to follow them whether in or out of the EU, so they are not a cost of "EU regulation”.
Leaving the EU may allow us to be more flexible on regulation
This does not mean that all EU regulations benefit the UK, or that collectively there is no cost to the UK economy.
There is clearly some potential for the UK to gain from extra regulatory flexibility outside the EU.
But the UK is still a lightly regulated economy compared to other rich countries, according to the Organisation for Economic Co-operation and Development. This suggests that regulatory gains from leaving the EU would be quite small, according to Professor Chalmers and Mr Portes.
And companies who want to export to the EU would still have to make sure that their products and services are in line with EU standards.
The EU single market doesn’t mean there are no barriers to trade at all
So the claim that the UK can sell without barriers to 500 million people is only partly right.
In areas covered by the single market, EU law does mean that if an exporter meets the requirements of an EU law, it will have access to the EU market.
This is a huge benefit to exporters, and to companies that supply them, but businesses that do not export may still have to adjust to EU regulations.
And it doesn’t mean exporters only have to abide by one set of regulations either.
EU laws frequently allow member countries to ‘derogate’ from EU rules in certain circumstances. In other words, they can adapt those rules to their own countries.
For example, EU food labelling laws give a detailed list of information that must be included on food packaging, such as the ‘use by’ date.
But the law allows governments to impose extra food labelling requirements to protect consumers or public health, so long as they have notified the European Commission and it has not objected.
Doing business across EU borders still means following other countries’ rules
More fundamentally, EU laws never govern all aspects of any trading relationship.
A British manufacturer exporting to France may be able to get access to the French market because its goods comply with EU law, but it will still have to comply with French contract, transport and competition law, and, if it sets up shop there, with French labour and planning laws.
All these rules are mainly set by individual countries, even though they may complicate business and increase costs.
The integrity of our elections is in danger, and we need your help
You’re probably here looking for facts. Thank you for that trust. But with the EU parliament elections on the way and more elections a possibility, we need to act now to make sure our elections are protected, before it’s too late.
Could you help protect our elections by becoming a Full Fact donor?
Misinformation isn’t new, but advancements in technology mean it can spread at an unprecedented scale. Our dangerously outdated election laws have not kept up with the digital age, putting our next elections at risk of abuse.
Currently, it’s possible for a candidate to run a thousand different political ads to win the same seat, promising something different to each group it targets. At the same time, there’s no law requiring those who publish online campaigns to disclose who they are or how they are funded. The opportunity for bad actors to manipulate election results is left wide open.
You may already know about our work to make public debate online more honest and transparent. Every day, we call out the most harmful misinformation on social media platforms when and where we see it. But right now, we’re urging the government to overhaul our election laws to make sure political campaigning is held to the same level of scrutiny online as it is offline.
This work all depends on the generosity of hundreds of people who all believe that for democracy to work, we need transparency. Our monthly donors help strengthen our voice, and show our politicians that this really matters. Would you consider joining them?
