How monthly insurance payments in Britain cost consumers extra

New research shows that millions of motorists and homeowners in Britain are paying up to £150 extra each year due to monthly insurance payment plans.

Millions of motorists and homeowners in Britain are facing an unexpected financial burden due to the way they pay for their insurance. New research reveals that choosing to spread insurance costs over monthly payments can add up to £150 annually to the total bill.

Despite regulatory efforts to curb excessive charges, many insurers continue to apply high interest rates to monthly payment plans. This practice is particularly impacting those who cannot afford to pay their premiums upfront, creating what consumer advocates call a poverty premium.

High interest rates on monthly payments

According to data from the Financial Conduct Authority (FCA)approximately 23 million car and home insurance policies in Britain are paid through monthly instalments. This makes premium finance one of the most common forms of consumer credit in the country.

Consumer group Which? conducted a survey earlier this year, examining 61 car insurers and 50 home insurers. The findings were alarming: some companies were imposing charges as high as 29.9% APR for customers opting to pay in instalments rather than clearing the full annual premium upfront.

For example, a motorist facing a £1,000 annual insurance premium could end up paying around £1,150 across the year if they choose monthly payments at 29.9% APR. This means the policy, which costs £1,000 upfront, could ultimately cost about £150 more when paid in instalments.

The impact of high APRs on consumers

The consumer group discovered that amongst insurers disclosing their rates, 20 car insurance companies and seven home insurance firms were imposing at least 25% APR. In contrast, the average car insurance instalment rate stood at 23%while the average for home insurance was 21%. These rates are only marginally below the typical credit card APR of 24.9%.

Campaigners argue that such fees are hard to justify given that insurers shoulder less risk than many traditional lenders. Unlike banks providing personal loans, insurers can frequently withdraw cover if customers fail to maintain repayments, thereby minimising potential losses.

Which? also pointed out considerable variations across the sector, with certain insurers providing interest-free monthly payment arrangements. The consumer organisation noted that charges have decreased since it started monitoring the market in 2026with average fees dropping by approximately five percentage points.

Regulatory scrutiny and consumer advocacy

The FCA has previously scrutinised the premium finance market and determined that broader intervention was not presently necessary. The regulatory body observed that average APRs had declined in recent years and that some firms had lowered rates following regulatory examination. Nevertheless, Which? maintains that millions of customers are still being overcharged.

Rocio Conchadirector of policy and advocacy at Which?, stated, “Millions of motorists rely on monthly payments to afford essential car insurance cover, yet many are still being charged interest rates comparable to an expensive credit card.”

Concha further emphasised that while some of the worst offenders have reduced their rates following regulatory scrutiny, the FCA’s weak approach appears to have been taken as a green light by the industry to keep charging extortionate rates. She urged the FCA to take further action to drive down rates across the market and ensure all consumers receive fair value.

The warning adds to concerns that households on tighter budgets often end up paying more for essential services than those able to pay large bills upfront. Consumer experts advise anyone renewing their insurance to check not only the headline premium but also the interest rate charged for paying monthly, as the difference can amount to hundreds of pounds over several years.
