The £15.9bn question

30 Nov

Why the NHS backlog keeps growing and what you can actually do to influence it?

Key takeaways

The national maintenance backlog is now £15.9bn, up 15.7% in a single year
High risk repairs alone account for over £3.5bn of that total, equating to %23 of the backlog
Ageing infrastructure, not funding, is the barrier estates leaders name most often
The backlog isn't one single number. It's split into risk categories that depend on accurate condition data
Only around 1 in 10 FM professionals trust their existing asset register as fully accurate
Condition-based asset modelling turns a static register into something you can prioritise from

The £15.9bn figure gets quoted a lot, and for good reason. But it hides something more useful underneath it, which is that the backlog isn't really one number at all. Under the ERIC return, backlog maintenance is broken down into risk categories, from high risk through to low risk, and the high-risk portion alone now sits above £3.5bn. That distinction matters more than the headline total, because a Trust with two buildings and identical backlog values on paper can have completely different actual risks depending on where that maintenance sits and what it affects.

Where the pressure is actually coming from

When estates leaders are asked what's driving the backlog, ageing infrastructure comes out ahead of everything else. Around 63% name it as the biggest barrier to bringing the number down, ahead of funding constraints at 53% and the raw scale of the backlog at 38%. That's a slightly counterintuitive result. It suggests that even with more capital, a lot of Trusts would still be constrained by buildings that are simply old, and by not knowing precisely how old-and-risky each part of the estate actually is.

Which brings up the second problem, and it's the one that gets talked about less. The data behind most prioritisation decisions isn't as solid as it needs to be. Roughly 1 in 10 FM professionals say their asset register is 100% accurate. A third don't know how often their asset register gets updated. Close to a third are still running it from spreadsheets. If the register itself is shaky unreliable, so is everything built on top of it. That includes the risk categorisation that feeds ERIC returns and ultimately shapes capital allocation.

Why a good asset register changes the conversation

A Trust that can say with confidence "this is what's high risk, this is what's significant, and here's the survey evidence behind both" is in a fundamentally different negotiating position than one working from a register that hasn't been walked in eighteen months. It's not just about winning more capital. It's about being able to defend a prioritisation decision at board level. Below questions are key to evaluate your current situation:

Is your asset condition data based on a recent physical survey, or extrapolated from when the building was last assessed?
Could your team produce the evidence behind a specific risk rating in the same meeting it's questioned, rather than after it?
Does your capital planning tool model risk and age together, or just list known defects?

Turning a number into a plan

This is the practical gap that Invida could help you to close with its condition-based maintenance and asset lifecycle management tools. Asset condition, age and risk are modelled visually and financially against the same underlying asset register, captured in the field through the mobile survey app rather than reconstructed from old paperwork. That means the risk categories behind an ERIC return, and the prioritisation decisions built on them, are both drawn from current data.

What this gives your Trust is a foundation for sharper, evidence based informed decisions. When the risk rating behind a prioritisation call is current and defensible, every exec board conversation and capital bid stands on firmer ground.

If any of this sounds like a gap in how your own estate data is currently held, it's worth a conversation. We can walk you through what condition-based planning looks like against your own asset register, and how we can assist you take to get there.
