Star fund manager Neil Woodford has put more money into Purplebricks, the estate agency which operates a hybrid model.

Woodford Investment Management has now raised its stake in Purplebricks to more than 25% by backing a private funding round which Sky News says values the company at over £100m. The value of the Purplebricks business has now soared five-fold in under a year.

Woodford’s investment is the second he has made in Purplebricks, having put in £7m last August which secured him a 30% stake in the company on its valuation at that time of £21m.

Purplebricks is the brainchild of brothers Michael and Kenny Bruce, who ran Burchell Edwards in the midlands before its sale in 2011 to Connells.

Other high-profile backers of Purplebricks include former Wonga boss Errol Damelin, and Paul Pindar, who was in charge of Capita.

Last autumn, Woodford said of Purplebricks that the company had “the vision, the technology and an experienced management team. With the funding at its disposal, I see a significant opportunity for the business to lead the market in changing the way we buy and sell houses.

“Given that the vast majority of property searches take place on the internet, a business that provides a ‘virtual’ offering without expensive high street offices can significantly undercut the current market.”

Purplebricks, which launched in April 2014, is said to be considering a stock market float next year. The business began by charging £599 including VAT, but a few months later charged £665 plus VAT. Its site now quotes £798.

At around the time of Woodford’s first investment, the firm was reported by Citywire to be targeting 85,413 instructions for the financial year ending July 31, 2015, and 100,849, representing 10% of all sales, for the following financial year.
