Plans to recoup mammoth taxpayer losses on Covid-19 loans are “woefully underdeveloped” and the Government has yet to assess the sheer extent of fraud, according to an influential Commons committee.

The cross-party Public Accounts Committee (PAC) said the Government does not have proper plans in place to manage the risks to the taxpayer from the bounce back loan scheme, either from fraud or borrowers unable to repay.

The National Audit Office (NAO) warned earlier this year that the taxpayer could be facing losses of up to £26 billion on the emergency loans made to businesses from fraud, organised crime or default.

But in its latest report, the PAC said the Government still does not have the data to assess the levels of fraud within the scheme – meaning the cost to the taxpayer could be even higher.

Government’s plans for managing risks to the taxpayer - from both fraud and borrowers who are unable to repay loans - are woefully underdeveloped

It added that the Treasury is yet to agree the process and protocols that lenders are expected to follow in recovering overdue loans.

The committee said: “Government’s plans for managing risks to the taxpayer – from both fraud and borrowers who are unable to repay loans – are woefully underdeveloped.

“Government does not have a counter-fraud strategy for the scheme and has not identified what types of fraud it will prosecute.”

The report comes after senior bankers cautioned on Monday that levels of fraud from taxpayer-backed Covid-19 loans are around five times higher than typical figures.

Bosses at Lloyds and Santander told MPs on the Treasury Select Committee that around 1% of bounce back loans have been taken out fraudulently.

Chancellor Rishi Sunak launched the bounce back loan scheme at the height of the pandemic, covering 100% of the loans and urging banks to ensure lending could be made quickly.

But the loan schemes had to be rushed out to help keep firms afloat in the initial spring coronavirus lockdown, which meant businesses were able to self-certify and lenders did not have to carry out any credit or affordability checks.

The PAC reiterated findings from its earlier report that slammed the Government for leaving the economy vulnerable to a pandemic, even though it was a known risk.

We targeted this support to help those who need it most as quickly as possible and we won’t apologise for this

Meg Hillier, chairman of the PAC, said: “Despite knowing that it was a case of ‘when’ rather than ‘if’ a serious pandemic hit the country, Government didn’t develop plans for how to support the economy.

“Rushing to get money out of the door after the fact didn’t allow for analysis of how many businesses needed this help, could benefit from it, or could repay it.

“Dropping the most basic checks was a huge issue that puts the taxpayer at risk to the tune of billions.”

The PAC is calling for the Government to provide updates on how it plans to deal with fraud on the schemes, while it said the British Business Bank should report back within two weeks with the latest fraud estimates.

It is also recommending the Treasury reviews whether it is right to continue relying on firms self-certifying, and must draw up recovery rules before repayments start becoming due on May 2021 to ensure a “fair and thorough recovery of loans”.

“For the remainder of this scheme, and future schemes, HM Treasury must better balance the interests of the taxpayer with the interests of businesses,” according to the report.

The PAC also highlighted that the schemes have likely reduced competition in the small business lending market, as the five biggest lenders have provided most of the loans.

A Government spokesman said: “We targeted this support to help those who need it most as quickly as possible and we won’t apologise for this.

“We are acting to crack down on Covid fraud, with lenders implementing a range of protections including anti-money laundering and customer checks, as well as transaction monitoring controls.”
