Royal & SunAlliance (R&SA) will push for growth of its property investors' book by expanding its portfolio and broadening scheme business.

James Purvis, director of R&SA property investors, said the insurer had spent the last few years upgrading its product offering, and "now we are much more about growth.

"Property investors will become a key area of growth for the insurer."

While modernising existing products, Purvis said R&SA had become more confident about what business it could transact.

He said: "Why shouldn't we write business we have previously avoided? We want to be much more confident and on the front foot."

This would not mean re-entering the US property markets, but concentrating on growth areas in the UK, he said.

Most recently the insurer added a provision for blocks of flats to its portfolio. R&SA research suggests the market to be worth £500m.

Purvis said: "There is currently a huge demand in the block of flats sector driven by an increase in 'city living'.

"Research has told us that brokers want a single point of contact for commercial and residential property business, which is what we now provide."

Property brokers Keelan Westall has added the insurer to its panel. Purvis said the aim was to write "millions of pounds" of new business through the binding authority.

"We are in for the long term," he said. "There is no point in dipping in and out of the market."

There are also talks to develop a property owners' scheme with London broker Stuart Alexander. The deal is expected to be finalised imminently.
