When we brought together representatives from across Scotland’s construction supply chain for our first roundtable in Scotland, one theme quickly became apparent: everyone wants to deliver homes efficiently and affordably, but the pressure to secure the lowest price can make achieving that more difficult.
Held in Glasgow alongside the Scottish Construction Summit and chaired by David Raine of Homes for Scotland, the discussion explored the practical barriers facing those involved in delivering new homes.
Although participants had different responsibilities and pressures, many of the challenges they face are interconnected. Decisions made at one stage of a project can have consequences much further down the line – particularly when commercial considerations outweigh technical input or when project plans change.
The lowest price isn’t always the best option
Cost is an unavoidable consideration in housebuilding. Developers need to keep projects viable, contractors must manage budgets and manufacturers need to remain commercially competitive. But as the discussion in Glasgow highlighted, there is a difference between achieving a genuine saving and simply choosing the cheapest option available.
As one attendee put it: “cheapest isn't always best”.
The point was not that cost should be ignored, but that price alone does not always tell the full story. A cheaper alternative may not offer the same performance or suitability as the product originally specified.
Participants described the frustration of investing time and technical expertise in developing a solution, only to see it replaced by a cheaper alternative at the commercial stage. In some cases, the alternative did not offer the same performance or meet the same requirements, and the original supplier was subsequently approached for help when problems emerged. This raised questions about how technical expertise can be carried through into the final procurement decision, rather than being lost when price becomes the overriding consideration.
The knock-on effect of decisions made in isolation
The discussion also highlighted the importance of involving contractors and installers in decisions made during design and specification. A solution agreed between a manufacturer and housebuilder may not work as intended if the people responsible for installing it have not been involved. Similarly, a product substitution made to address availability or cost pressures can have implications for performance, compliance and the wider design.
Participants also described the difficulty of planning around uncertain timescales, with projects potentially slipping by months or even a year, while specifications and material requirements can change along the way. Manufacturers may be planning production and supply around forecasts made months in advance, while contractors are focused on the immediate demands of the site.
What became evident from participants is that these different timescales and pressures can create friction, particularly when prices change, materials become harder to source or a specification evolves between the initial design and work starting on site. Teams are expected to maintain budgets and programmes while responding to circumstances that may have changed since the original decisions were made.
The real challenge is to make sure those changes are communicated early enough for the relevant people to assess their implications. A decision that appears to solve an immediate problem can otherwise create another one further down the line.
Collaboration needs to work commercially, too
Closer collaboration was a recurring theme throughout the roundtable, but the discussion also recognised that it is not always straightforward to achieve. The group highlighted that bringing people together is only part of the answer.
Competitive tendering can make businesses reluctant to invest time in developing solutions with a potential customer if there is no guarantee they will ultimately secure the work. Equally, commercial teams are under pressure to demonstrate savings and manage budgets, even where a higher initial price might offer better value over the lifetime of a project.
The conversations made it clear that the answer is not simply to encourage businesses to work together. It is to make sure the value of that collaboration is recognised when commercial decisions are made. That means looking beyond the initial purchase price to consider product suitability, the technical expertise behind a specification, reliability of supply and the potential cost of getting things wrong. Changes and variations also need to be addressed at the right time, rather than leaving their commercial implications unresolved until a project is nearing completion.
Attendees agreed that there is a role for every part of the supply chain in making this work. Manufacturers need opportunities to explain the benefits and limitations of their solutions; contractors and installers need to be able to share practical feedback; and developers need to consider how procurement decisions affect the wider project.
Crucially, collaboration needs to involve the right people at the right time.
A shared challenge needs a shared response
One of the most useful aspects of bringing different parts of the supply chain into the same room was the opportunity to hear how the same pressures and challenges look from different perspectives.
The discussion reinforced that businesses are often working towards the same outcome, but can struggle to reconcile their individual priorities along the way. A manufacturer planning ahead, a contractor responding to immediate site demands and a developer managing a budget may approach the same issue differently – even when they ultimately want the same result.
Better understanding of these pressures is an important starting point. It helps explain why challenges arise and why solutions need to account for the realities faced by businesses across the whole process, rather than focusing on one stage or one organisation.
This is not about removing commercial scrutiny or expecting every decision to favour the most expensive option. It is about looking at the bigger picture and recognising that the cheapest solution at one stage may not deliver the best result overall.
As Scotland looks to deliver more homes, the industry will need to balance cost, quality, compliance and practical delivery. Making better use of the expertise already available across the supply chain could help do that more effectively.
The roundtable highlighted that improving delivery is not simply about asking individual businesses to work harder. It is about understanding how decisions affect one another, recognising the value of technical input and considering the consequences of choices beyond the immediate price.
A huge thank you to David Raine for chairing this discussion and to everyone who joined us in Glasgow and shared their perspectives, including:
