UK car and home insurance premiums are under scrutiny because many households have seen renewal prices rise much faster than ordinary inflation. The concern is not just that cover costs more, but whether the market is working well enough for customers who often have limited choice about buying protection. Before renewing, compare like-for-like quotes, check the excess and exclusions, and avoid cutting cover below what you genuinely need.

Why premiums are being questioned

The pressure has been strongest in motor insurance because driving without at least third party insurance is illegal in Great Britain unless the vehicle is properly declared off road. GOV.UK explains that a vehicle must normally be insured unless it has a Statutory Off Road Notification, commonly called a SORN (GOV.UK, 2026).

Reports have pointed to steep annual increases for many drivers. The Guardian reported that ABI figures showed UK car insurance premiums rising by 34% from the final quarter of 2022 to the final quarter of 2023, while motor claims payouts rose by about 18% in 2023 (The Guardian, 2024). That gap has helped fuel calls for competition authorities and regulators to look more closely at pricing, margins and value.

Home insurance has also become more expensive, with insurers pointing to higher building repair costs, labour shortages, severe weather claims and inflation in replacement goods. For homeowners with a mortgage, buildings insurance is usually required by the lender, so a sharp increase can be hard to avoid.

What regulators can and cannot do

The Financial Conduct Authority regulates the conduct of insurers and brokers, including how firms treat customers, communicate terms and deliver fair value. The FCA’s consumer guidance says customers should be alert to financial products that are unsuitable, unclear or poor value (FCA, 2026).

Regulators do not usually set insurance prices. A competition review would more likely ask whether the market is functioning properly: whether customers can compare policies easily, whether pricing is transparent, whether loyal customers are disadvantaged, and whether barriers stop new providers competing.

The FCA has already banned “price walking” in home and motor insurance. This means renewing customers should not be charged more than an equivalent new customer purely because they are renewing. It does not freeze renewal prices. Premiums can still rise if the insurer changes its view of risk, claims costs or wider market conditions.

What this means for your renewal

Do not assume a large renewal increase is final. MoneyHelper’s insurance guidance encourages consumers to compare cover, understand exclusions and choose protection that fits their needs rather than buying on price alone (MoneyHelper, 2026).

For car insurance, compare the same level of cover, such as comprehensive against comprehensive. Check the compulsory excess, voluntary excess, no-claims bonus protection, courtesy car terms, windscreen cover and legal expenses add-ons.

For home insurance, check the buildings sum insured, contents limits, single item limits, accidental damage, escape of water terms, flood exclusions and alternative accommodation cover. A cheaper policy can be poor value if it removes protection you would reasonably expect to need. Underinsuring your home contents or rebuild cost may reduce the premium now but can leave you short if you claim.

If you think your insurer has treated you unfairly

A high premium alone is not always evidence of unfair treatment. However, misleading renewal information, unexplained charges, poor claims handling, failure to apply an agreed discount or unclear policy wording may justify a complaint.

First, complain to the insurer or broker in writing and keep copies of renewal notices, quotes and policy documents. The Financial Ombudsman Service says consumers should complain to the financial business first, then may be able to bring the complaint to the ombudsman if they are unhappy with the response or the firm has not replied within the relevant time limit (Financial Ombudsman Service, 2026).

Practical next step

If your renewal has risen sharply, get at least three like-for-like quotes before the renewal date. Ask your current insurer to explain the increase and whether it can offer a better price without reducing essential cover. Keep the policy wording and key facts document, because the cheapest quote is only useful if it still protects the risks you need covered.
