Inflation is rising. Bureau contract costs are following

In recent years, inflation has exceeded 10%, and many bureau contracts have followed it upward. For organisations operating under uncapped RPI-linked terms, this has resulted in cost increases of 30–40% over a three-year period, despite no change in volumes.

This is not driven by demand. It sits within the contract.

As inflation rises, these clauses apply automatically. Each annual uplift builds on the last, gradually altering the cost base. With fuel price volatility and ongoing geopolitical pressure, inflation is expected to settle above historic norms, with most forecasts pointing to levels above 3%. That resets expectations.

Within bureau contracts, the impact is direct. Many agreements still include RPI-linked increases without caps, meaning costs continue to rise regardless of changes in usage.

For organisations with multi-year agreements, this creates a compounding effect that is only now becoming fully visible.

The RPI contract trap

RPI-linked clauses are often accepted as standard when contracts are agreed.

Attention is usually directed towards headline pricing, minimum commitments and service scope. Inflation terms receive less scrutiny and are treated as background detail.

Many existing agreements reflect those assumptions.

Costs increase gradually, with annual uplifts applied year after year. Each adjustment builds on the previous one.

The scale of those increases has changed.

Cost rises of 30–40% are now being seen in contracts where usage has remained stable.

This is not always immediately visible. Increases are often attributed to general pricing conditions rather than the mechanics of the contract. Bureau spend is frequently spread across multiple teams or budgets, making the driver harder to isolate.

By the time the full effect is recognised, it has already been incorporated into ongoing spend.

Contract structures are also diverging. Some organisations now operate with capped increases or alternative measures such as CPI. Others continue with uncapped RPI-linked terms.

Where those structures remain, costs increase more quickly over time, even where usage is similar. This shifts the overall cost position away from the wider market.

Why costs are rising without a change in usage

Cost increases of this nature rarely originate from changes in demand.

1. The first indication is often the bill

For many organisations, the issue becomes visible through rising spend.

Total costs increase year on year, despite stable volumes, unchanged product mix and consistent demand. In some cases, usage may decline while costs continue to rise.

This is often attributed to broader pricing pressure.

2. The mechanism sits within the contract

Where RPI-linked clauses are in place, increases are embedded within the pricing structure. Each uplift builds cumulatively, and over time the impact appears in total spend rather than individual charges.

There is no single trigger event. Pricing adjusts steadily, independent of usage.

3. Legacy pricing compounds the effect

This often sits alongside pricing that has not been revisited.

Contracts are extended or rolled forward without a clear understanding of how rates compare across the market. Confidentiality limits visibility, and without external comparison, pricing is rarely challenged.

Applying inflation to those baseline rates accelerates the increase.

4. Scale magnifies the impact

For organisations operating at scale, small differences in unit pricing become significant.

When those rates are applied across large volumes and increased annually, the cumulative effect can materially alter total spend.

5. Recognition tends to come late

Cost increases accumulate gradually and often only attract attention once they reach a level that is difficult to absorb.

By that point, they have already been applied across multiple billing cycles and form part of the ongoing run rate.

Focus often remains on usage or supplier behaviour, while the primary driver sits within the contract.

Implications for cost control

As pricing moves independently of demand, it becomes less responsive to operational levers.

Over time, this reduces visibility and makes costs harder to forecast, explain and contain.

Renegotiating inflation terms

For many organisations, the priority is to regain control without waiting for contract renewal.

This begins with understanding how current terms compare across the market. Without that context, it is difficult to assess whether inflation clauses remain appropriate or whether pricing has moved out of line.

Once that position is established, discussions become more focused.

The areas that drive cost are:

• how annual increases are applied

• whether those increases are capped

• whether RPI remains appropriate

Targeted adjustments in these areas can materially change how cost evolves over the remaining contract term.

These elements are often only reviewed at renewal. By that stage, the cost base has already shifted and the scope for correction is reduced.

Where supported by market context, suppliers will engage in discussion. The focus moves towards how terms compare across similar organisations.

Each cycle of increases raises the baseline for the next. Acting earlier limits the cumulative impact and reduces the effort required to address it later.

For organisations with significant data spend, this comes down to control. Aligning inflation terms with current conditions stabilises cost and improves forward visibility.

What this means for senior leaders

RPI-linked pricing is now influencing cost in ways that were not anticipated when many agreements were signed.

Contract structure is shaping spend more than usage itself. As increases build over time without a clear link to activity, visibility reduces and control becomes more difficult.

For senior stakeholders, this has clear implications:

• forecasting becomes less reliable

• cost is harder to explain and challenge

• pricing behaviour diverges from demand

Organisations that address this effectively focus on how pricing behaves within existing agreements and act where it no longer reflects current conditions.

This often starts with a comparison against organisations with a similar operating profile.

Without that reference point, it is difficult to determine whether cost increases are aligned with the market or driven by terms that have remained unchanged.

The issue is often approached through pricing alone, rather than the structure of the contract. That distinction influences how quickly cost can be brought back under control.

For organisations with large data spend, the financial impact can be significant over the life of an agreement.

Maintaining control depends on understanding three things:** how cost is established. how it evolves over time, how it compares to the wider market.**
