Operating profit at the housebuilder rose 15 per cent to £151.1 million in 2018, with inflation pushing the average selling price £10,000 higher to £249,000.
Operating margin surpassed the firm’s 20 per cent target for the first time and was “ahead of plan”, up from 19.5 per cent in 2017, while revenues were 11 per cent higher at £747m.
However, net profit fell to £82.9m, down from £87.7m, as finance costs more than doubled to £51.1m due to a change in the company’s debt structure taking effect in October 2017.
The firm hailed the strength of the UK housing market, particularly demand for mid-market homes and the extension of the UK government’s Help to Buy scheme to 2023.
It completed 3,170 homes in the 12-month period, 735 of these in Scotland, representing a 14 per cent rise from the previous year.
Miller reported a “rigorous approach” to land selection although its owned landbank grew 10 per cent to 9,174 plots, supported by a further 3,350 controlled units.
The firm said it remains “on track” to deliver its strategic target of building 4,000 homes annually by 2021 and cheered a 6 per cent rise in forward sales at £292m.
The group also launched its West Midlands arm in 2018 and grew head count 11 per cent to around 970 staff across all divisions.
Chief executive Chris Endsor said: “Demand for mid-market homes continues to be strong, underpinned by low interest rates and Government support with Help to Buy extended to 2023.
“We continue to have confidence in the resilience of the UK regional housing markets in which we operate and remain committed to our strategy of growing volumes incrementally to 4,000 units.
“Market conditions are continually monitored with the optionality in our business planning enabling us to adapt land buying depending upon demand and opportunities.”
