Moneysupermarket is putting out a challenge to Direct Line. The aggre-gator giant has invited the insurer to join its panel – for free.

Moneysupermarket said it wants to smooth over a longstanding anti-aggregator battle with the direct insurer by showing the benefits of being on a price comparison site.

Typically, insurers on Moneysupermarket’s panel are charged a cost-per-click fee, but Direct Line is being offered the opportunity to gain as much business as it can without paying a penny.

The insurer declined, but a source with Moneysupermarket said the offer still stands if Direct Line experiences a change of heart.

Meanwhile, the aggregator will wait by its litle red phone, just in case.
