Certainty is a currency: what public buyers should demand in exchange for longer contracts
Every supplier in public construction says the same thing: give us visibility and we will invest. The government's guidance on longer term contracting takes that bargain seriously, and it is refreshingly honest about both sides of it. A contract beyond three years is a grant of certainty, and certainty is valuable. The question the guidance keeps forcing is whether the buyer actually collects the price: investment in Modern Methods of Construction, year-on-year efficiency gains, and standardisation that compounds. Too many long contracts hand over the certainty and collect nothing but lock-in.
The bargain most authorities only half strike
The economic logic is sound and the case studies prove it. The Department for Education gets a 70 per cent pre-manufactured value floor, a harmonised rates book and a ratchet that discounts build rates as volumes grow, because it brought a 10 year spending settlement and a weekly published pipeline to the table. The Ministry of Justice priced one prison properly and then built three more on the same baseline, with 80 per cent of value still competed transparently inside the alliance. In both cases the certainty was real, so the returns were real.
Contrast that with the failure mode the guidance quietly describes: an authority with three years of funding and no long-term strategy signs a long contract anyway, the pipeline underdelivers, supplier trust and cash flow suffer, and the relationship curdles. Failure to deliver against the pipeline is not a neutral event; it damages the market you were trying to strengthen. If you cannot honestly promise the volume, do not buy the discount.
Break clauses are not pessimism, they are the design
There is a mindset that treats break clauses and review points as signs of weak commitment. The guidance takes the opposite view: they are what make a long commitment safe to give. Disaggregation by category, performance-based breakpoints and upper and lower volume limits are the mechanisms that let an authority stay in a ten year relationship without being hostage to it, keep SMEs in the game, and bring in new solutions when the market moves.
The same is true of measurement. A long contract without SMART KPIs, annual benchmarking and honest satisfaction surveys is not a partnership, it is a standing order. The prison alliance's KPI structure is instructive: 34 indicators in tiers, with the incentive pot unreachable through business-as-usual performance. Incentives priced for over-performance, not attendance, are what stop year six of a framework feeling like year one of complacency.
Kill the mini-competition habit, carefully
The Gold Standard recommendations the guidance highlights, longer call-offs and portfolio awards instead of repeated mini-competitions, will feel uncomfortable to procurement teams raised to equate competition frequency with value. But the industry critique is fair: perpetual mini-competitions burn supplier margin on abortive bids, reward bid-writing over delivery, and destroy the volume certainty that funds factory investment. DfE's performance-based allocation shows the alternative: work flows to the suppliers whose measured delivery earns it.
The discipline that makes this defensible is records. Direct allocation without documented performance data is favouritism; with it, it is a performance regime. Authorities that keep clean, comparable delivery data across their portfolio can justify continuity to auditors and to the market. Those that do not will retreat to mini-competitions, not because they are better, but because they are easier to defend. Build the evidence base and the better model becomes available to you.
The takeaways
- Only grant long-term certainty you can actually fund: a broken pipeline promise damages the market and your reputation.
- Collect the return: pre-manufactured value floors, rate ratchets and improvement plans are the price suppliers should pay for continuity.
- Design in performance-based break clauses, volume limits and category disaggregation from day one.
- Replace mini-competition churn with performance-based allocation, backed by clean delivery data.
- Incentives should reward over-performance, never business as usual.
