Leeds-based smart home technology firm BOXT has signed a deal with Google as it targets international expansion.

The agreement enables BOXT to offer voice controlled heating as standard, supplying a free Google Nest Learning Thermostat and Google Home Mini with every new boiler it installs.

The deal forms part of the company’s plans to raise £20m, which will be used to expand overseas, double its smart home installers to 2,000, and release a raft of new smart home devices in the next 12 months.

"Home installation is ripe for disruption and we want BOXT to be the first choice for customers who want to install heating, cooling or any smart technology in their home," said Andy Kerr, co-founder of BOXT.

"We've developed our platform to ensure that the process for customers is easy, transparent and always good value – and with no hidden costs or antiquated sales techniques."

The business reported a turnover of £20m in its first full year of trading and projects that this will double the current financial period, enabling BOXT to expand internationally.

The company was founded in Leeds by three former executive directors from boiler installation business Help-Link – Mel Butler, Alan Dickinson and Andy Kerr – together with Keith Jones, a former managing director from Wolseley's Plumb Center.
