[3] The outbreak of the Second World War led to the company's abrupt cessation of private housebuilding and the start of Miller's construction business, which continued to grow following the end of the conflict.

The company's senior management declared their intention for Miller Homes to move into the top ten housebuilders in Britain.

In September 2010, Miller Homes recorded a pre-tax loss of £27 million, some of which was attributed to the costly debts it was carrying.

[13][14] In April 2011, shortly after rival firm McInerney Holdings' entry into administration, Miller Homes secured a management contract valued at £100 million relating to ten sites previously owned by the failed company.

[21][22] During September 2015, Miller Homes announced revenues of £229.7 million over last six month trading period, a 32 per cent year-on-year increase.

[23][24] In August 2017, Miller Homes was purchased by the European private investment firm Bridgepoint Group via a deal valued at £655 million.
