[4] During this period, Amey Roadstone continued to undertake several major projects on behalf of the British government, included construction work at Mount Pleasant Airfield on the Falkland Islands, which was completed in 1986.

[4] During 1989, Hanson purchased Amey Roadstone from Consolidated Gold Fields, returning the firm back to private ownership.

In 1995, Amey was refloated on the London Stock Exchange; around this time, the company's management team made the strategic decision to focus its efforts upon the support services delivery sector.

[9][10] A statement issued by Ferrovial noted that the purchase allowed it greater access to the lucrative British market, particularly for public–private partnerships.

[16] In January 2016, Amey acquired Travel Point Trading Ltd (TPT), a strategic asset management consultancy with a strong presence in the rail sector in the United Kingdom.

[19][20] In August 2018, Amey completed the acquisition of Ministry of Defence (MoD) housing maintenance contracts previously run in joint venture with Carillion.

[21] Amey retained its Oxfordshire links for a number of years, with their head office in the Sherard Building, Oxford Science Park, from 2004-2018.

[28] (However, in February 2020, it was announced the Birmingham contract would end in March 2020; Kier Group was appointed as interim contractor for 15 months while the council sought a permanent replacement for Amey.

On revenues of £2.32bn, a £208,000 pre tax profit was wiped out by exceptional items, including £123m on the Birmingham highways contract, and a £314m write-down on Amey's waste collection and utilities businesses.

[31] In December 2019, Ferrovial started to offload loss making parts of the business in the United Kingdom, appointing PricewaterhouseCoopers to find buyers for Amey's utilities and environmental services divisions.

[36][37] In February 2021, Ferrovial launched a fresh attempt to sell Amey, enlisting Morgan Stanley to run the sale.

Parent Ferrovial planned to convert £112m in debt into equity to support the business, while also seeking to divest its services portfolio including Amey.

[42] In September 2021, private investment firm Buckthorn, which included former UK chancellor Philip Hammond among its partners, was reported to be among at least two bidders for Amey.

[3] The deal excluded Amey's waste treatment business (which remained part of Ferrovial group) and, subject to regulatory approvals, was expected to complete by the end of 2022.

[2] In January 2023, Amey named former government minister Lord Colin Moynihan as its new chair, succeeding Ian Tyler.

It joined Amey Consulting’s Advisory & Analytics business, which already used data science for clients including Network Rail, National Highways and Transport for Wales.

Amey is involved in consultancy in the civil engineering industry, with a wide range of design and asset management services offered.

[51] During the 2010s, Amey partnered with Canadian defense electronics specialist CAE Inc. to form a joint venture company, AmeyVTOL, which specialises in the manufacture of unmanned aerial vehicles.

[68] On 9 March 2018, Amey lost an employment tribunal following the sacking of two maintenance workers with over 45 years experience at HM Prison Liverpool.

[69] In March 2020, during the COVID-19 pandemic in the United Kingdom, an Amey HR executive said company workers would not receive any special sickness benefits as he believed coronavirus was "less severe" than normal influenza.
