Underwriting agency Select & Protect, which avoids using brokers to sell its household policies, has increased its book by £1 million in the last three months due to the mortgage boom.
The Southend-based company sells its household policies through a 2,500 agent network of mortgage brokers, estate agents and financial advisers.
In the last three months, Select & Protect has added £1m of premium income on to its book to make a total of £10m.
The company has now doubled its account in four years.
Much of the increase is attributed to the popularity of its New Homes policy, tailored for houses with a New Homes Building Council guarantee. There are two levels of cover - Ultima and Economy, which are underwritten by Hiscox.
"We have been helped not only by the property boom, but also because there is a mortgage boom with people looking to re-mortgage," said director James Wallis.
"Many consumers are aware that household and contents can be cheaper if the policy is not tied to a mortgage."
