Consultants on construction projects

In the construction industry, the term ‘professional consultant’ is used to describe the large number of professionals who provide services on or in connection with construction projects. See Practice Note: Roles of professional consultants—construction projects. These consultants are involved at all stages of the construction process, from inception to completion and beyond. Many are involved in design whereas others provide other professional services such as supervision, monitoring and testing. Some are heavily involved from start to finish and others only have a limited role at a particular stage of a project. On most large construction projects, the same principal consultants will be engaged:

•
architect
•
structural or civil engineer
•
building services engineer or mechanical and electrical engineer
•
quantity surveyor or cost consultant
•
project manager or employer's agent

Scottish Government publishes Building Safety Levy Expert Advisory Group minutes

The Scottish Government has published minutes from Building Safety Levy Expert Advisory Group meetings held on 4 November 2025 and 28 January 2026, both released on 5 February 2026. The minutes reveal concerns from members that the Levy Free Allowance threshold of 19 units had not been consulted on with stakeholders, with members strongly favouring setting this threshold in primary legislation rather than regulations. Scottish Government officials clarified their intention to set the Levy Free Allowance in regulations alongside rates and confirmed the Minister's commitment to strengthening reporting requirements in the Bill through government amendments expected on 4 February. The Levy commencement has been delayed from April 2027 to April 2028, with indicative rates to be published in June 2026 alongside an updated Business and Regulatory Impact Assessment. The group supported aligning the Scottish approach with the methodology used in England, with the Levy aimed at generating £30m annually.

Scottish Government launches consultation on housing delivery incentives and penalties

The Scottish Government has launched a consultation seeking views on measures to accelerate the build-out of homes on sites already identified for housing development, in response to falling housing starts and completions despite a substantial pipeline of consented land. The consultation supports the Housing Emergency Action Plan and related planning commitments, and examines whether incentives, penalties or other interventions could increase delivery rates, including for small and medium-sized housebuilders, within a plan-led, infrastructure-first framework under National Planning Framework 4. It is informed by evidence that slow delivery is driven primarily by post-consent factors such as market absorption rates, viability constraints, infrastructure costs, public sector risk exposure and limited developer capacity or commitment, rather than by the planning permission process itself. Drawing on previous reviews and research by bodies including the Competition and Markets Authority and the Scottish Land Commission, the consultation outlines potential approaches such as land assembly, public sector-led development, reform of compulsory purchase and sales powers, and policy tools to influence build-out rates, and notes that any future action may require legislative change in the next parliamentary session and would be subject to appropriate impact assessment. The consultation closes on 30 April 2026.
