Why your materials contract savings are probably eroding, and what to do about it

It’s a familiar story for Scottish RSLs and housing associations. You’ve put proper effort into your materials tender. Good rates secured, quality merchants appointed, savings signed off by the board. Job done.

Except it isn’t. Because a few months in, the contract gets handed to the head of repairs to manage on top of everything else they’re doing. They’ve got a responsive repairs team to run, tenants to keep happy, and targets to hit. Checking whether merchants are applying contracted prices, or whether operatives are buying off-contract from their preferred branch, tends to slip down the list.

Research by World Commerce & Contracting suggests poorly managed contracts cost organisations an average of 9% of annual turnover through value leakage. For a Scottish housing association or council with a significant materials spend, that’s a number worth paying attention to. This guide is about how to stop it happening.

What the guide covers

This is a practical guide written from real experience of working with Scottish housing associations and local authorities on materials contracts. It won’t tell you things you already know. It’ll tell you what the organisations that manage this well are actually doing differently.

Getting price management under control Accurate, impartial data is the foundation of good materials contract management. Without it, you’re relying on information that comes directly from your merchants, who have their own commercial interests. The guide covers how to build the kind of independent visibility that lets you spot whether operatives are paying more than contracted rates, whether certain merchants are overcharging on high-volume products, and how to respond to price increase requests with something more robust than goodwill.

It also covers practical tools including the Construction Materials Price Index (CMPI) as a quick read on market conditions, and PfH Scotland’s own Building Materials Pricing Summary and Sentiment Report, which give a more detailed picture of where costs are heading in the social housing supply chain.

Making the most of what your merchants can offer Keeping value in a materials contract isn’t purely about policing your suppliers. It’s also about working with them in a way that makes the relationship genuinely productive for both sides. If merchants can’t make their margins, stock availability suffers, first-time fix rates drop, and tenant satisfaction follows. The guide looks at how to build fairer, more collaborative supply chain relationships, and how to harness the innovation that good merchants are increasingly able to offer, from van stock technology and new fulfilment methods through to aggregating demand across planned investment works to negotiate better terms.

Understanding what your operatives are actually doing Spend data tells part of the story. But speaking to your repairs teams directly often tells you more. Are certain operatives buying from branches near their current jobs rather than contracted merchants? Are they leaving jobs to collect materials because their van stock isn’t right? Are there products they’re consistently buying outside your approved range because they prefer a particular brand?

The guide draws on the Rethinking Repairs and Maintenance (RERAM) guidance, developed by the Chartered Institute of Housing and the National Housing Federation, which makes a strong case for involving frontline colleagues in reviewing how repairs and maintenance works in practice. That same principle applies directly to materials procurement. The people buying materials every day have insights that management information alone won’t surface.

Culture change: the part most organisations skip When housing associations ask how to get operatives to follow procurement processes, the honest answer is that compliance policies alone won’t do it. Culture change is what actually shifts behaviour, and it’s the part of materials contract management that tends to get left out of programme planning.

It takes time and it has resource implications, which is exactly why it needs to be built into your procurement timeline from the start rather than bolted on later. The guide covers what culture change looks like in practice, from demonstrations and internal communications through to mentoring and team-based initiatives, and why it’s worth treating it as a core part of your approach rather than a soft add-on.

Who this is written for

Repairs managers and heads of housing maintenance in Scottish RSLs who are carrying contract management responsibilities alongside a full operational workload. Procurement officers in Scottish housing associations and councils, particularly those managing portfolios of 5,000 to 20,000 homes, who want to be more confident that the savings secured at tender are being maintained through the contract term. Anyone who’s noticed the gap between what a materials contract looked like on paper and what it’s delivering in practice.

You don’t need to overhaul your whole approach at once. The guide is structured around four practical areas where targeted effort tends to make the biggest difference.
