"I'm extremely aggrieved that nearby homes have solar panels and batteries, making their bills a quarter of what ours are. This feels unfair." That's a real resident, responding to a post-installation survey after their own retrofit work was complete, not mid-argument with a surveyor, not venting on a doorstep, but reflecting, afterwards, on a disparity nobody had ever properly explained to them.
Our research into communication in domestic retrofit found this exact grievance surfacing again and again, in different forms, at different stages of the resident journey. Sometimes it starts even earlier, with a surveyor trying to give good news: a resident is told they're likely in line for solar panels or new windows "because your neighbour's got it." When the household is later offered loft insulation instead, a throwaway comment from months earlier becomes a formal complaint. In both cases, the underlying issue is identical. Nobody managed the gap between what a resident expected and what the programme could actually deliver.
It's tempting to treat expectation-setting as an administrative detail, get the eligibility letter right, and the rest takes care of itself. That underestimates how much weight a single early conversation carries.
Trust is built as much by honest expectations as by successful delivery. A resident who was told, even informally, that they'd get one thing and received another doesn't just feel disappointed about the measure. They now have concrete evidence that what they're told during this programme might not be reliable, and that suspicion doesn't stay contained to the original issue. It follows the resident into every subsequent conversation, at exactly the point in a project where cooperation, access and patience matter most.
The fairness dimension makes this worse, not better. Retrofit is frequently delivered street by street, scheme by scheme, which means residents are unusually well placed to compare notes with neighbours who received different measures. Whether or not the eligibility criteria behind that difference were ever properly explained, a resident experiences an unexplained disparity as arbitrary, and arbitrary is precisely where trust breaks down fastest.
Managing expectations well is less about promising less than about being precise, early, about what's actually known versus what's still uncertain, and resisting the temptation to fill that uncertainty with something reassuring but unconfirmed.
That applies to measures: a surveyor who is honest that eligibility for a specific technology depends on a technical assessment still to come, rather than speculating based on what a neighbour received, sets up a very different conversation five months later than one who let a resident's hopes run ahead of the facts. It applies to timelines too. Retrofit programmes routinely stretch many months between survey and installation, long enough that residents can reasonably assume a survey means an imminent start, unless someone tells them otherwise, clearly, at the point the survey happens.
It applies just as much to money. Over-promising on energy bill savings, alongside timelines and disruption, is one of the most common ways initial buy-in gets secured at the cost of confidence later. A resident told to expect a specific saving, and who then doesn't see it reflected on a bill shaped by factors well outside any contractor's control, has been handed a concrete, dated reason to distrust everything else they were told. Organisations that instead communicate openly about uncertainty, and explain why a plan or a figure might change, are the ones residents keep believing months into a project.
And it applies to something smaller but just as corrosive: what happens when a resident asks a question nobody can answer on the spot. Committing to find out, and actually following through, protects trust. Guessing, or promising a callback that never happens, is a miniature version of exactly the same mistake as overpromising a measure at survey stage.
Some of this is simple human instinct. Delivering disappointing or uncertain news is uncomfortable, and a hopeful, slightly overstated answer is often the path of least resistance in the moment, particularly for people who are new to a role or keen to keep a conversation positive. Nobody sets out to overpromise. It happens because the honest answer, "I don't know yet" or "that depends on things we haven't confirmed," feels like a worse thing to say than it actually is.
Structural fragmentation makes it worse. A single retrofit journey can pass through five to ten different people, and a resident's expectations get shaped by whichever of them happens to be speaking at the time, not necessarily the person with full visibility of what's actually been agreed. Without a shared, disciplined line on what can and can't be confirmed at each stage, well-meaning people will keep filling gaps with their best guess, and best guesses are exactly what create the disparities residents later experience as unfair.
There's also a deeper structural version of the same problem. The Sustainability Lead at a major housing association argues the fix has to be structural, not just behavioural: "residents need to be able to have that one place to call and find out what's going on, rather than being sent from one person to another." When a resident calls with a question and gets bounced between customer service, the retrofit team and the contractor, each handoff is itself a small broken expectation, that someone, somewhere, would actually be able to help. That experience teaches residents not to trust the next reassurance either, regardless of how honestly it's meant.
Agree, explicitly, what can and cannot be confirmed at each stage of a project, and make sure everyone customer-facing, not just surveyors, is working from the same understanding. Ambiguity filled in individually by well-meaning people is where most broken expectations start.
Explain eligibility differences proactively, before a resident has to ask why a neighbour got something they didn't. A brief, honest explanation offered upfront lands very differently to the same explanation delivered defensively after a complaint.
Separate what a measure will do from what it will save. Communicating clearly about the physical improvement to a home carries far less risk than a specific financial promise shaped by variables nobody controls, and it's usually just as persuasive.
And build the discipline to say "I don't know yet, and here's when I will" as a practised, comfortable response, not an admission of failure. That takes rehearsal. It's an uncomfortable thing to say confidently the first time, and confidence built under pressure, rather than assumed, is what stops the instinct to fill the gap with something more reassuring but untrue.
Every one of the six communication skills in this series is really about the same underlying idea: that trust in a retrofit programme is built and lost in specific, identifiable moments, not as a vague overall impression. Managing expectations may be the clearest example of all, because the moments where it fails are so precisely traceable back to a single sentence, said with good intentions, months before the consequences show up.
