Getting people to actually do something like pay council tax on time, register for a service online instead of calling, turn up to a hospital appointment, put the right bin out on the right day is one of the hardest parts of public sector communication. You can run the most polished campaign in the world and still watch behaviour stay exactly the same, because awareness and action aren’t the same thing.

That’s the gap the EAST framework was built to close. Developed by the UK’s Behavioural Insights Team (BIT), EAST takes a decade of behavioural science and distils it into four principles any comms or policy team can apply without a psychology degree. It’s become one of the most widely used behaviour-change models in UK public sector communications, and it sits comfortably alongside the OASIS framework as a tool for the audience insight and strategy stages of campaign planning.

Here’s what EAST actually means, how each principle works in practice, and how Orlo’s platform can support each stage.

EAST stands for Easy, Attractive, Social, Timely – four conditions that make someone more likely to adopt a behaviour you want to encourage. BIT first published the framework in 2014 and refreshed it in 2024 to reflect ten years of additional research and real-world application. It’s since been cited in academic literature close to 350 times, despite being written for practitioners rather than academics, a good sign of how well it’s held up outside the lab.

The idea behind EAST is simple: most of us don’t make decisions the way traditional campaigns assume we do. We’re busy, distracted, and running on habit far more than we’re weighing up pros and cons. EAST doesn’t ask you to change what you’re asking people to do, it asks you to change how you’re asking.

People are far more likely to do something when the effort involved is low. Every extra step, every unclear instruction, every additional form field is a chance for someone to give up or put it off. Reducing friction through simpler language, fewer steps, and sensible defaults is consistently one of the most effective ways to shift behaviour, because it works even on people who were never paying close attention in the first place.

In a local government context, this might mean cutting a permit application from twelve fields to four, offering a form that’s already pre-filled with data you hold, or making the desired option the default rather than something residents have to actively opt into.

Attention is scarce, and a message that doesn’t stand out doesn’t get acted on, however important it is. Attractive doesn’t mean flashy for its own sake it means personalised, visually clear, and relevant enough to the individual that it cuts through. Colour, imagery, personalisation and framing can all make the difference between a message that’s read and one that’s ignored.

For a council or public body, this could be as simple as replacing a dense paragraph of policy text with a clear visual, or personalising a reminder so it reflects the resident’s actual situation rather than reading like a mail-merge.

People take enormous behavioural cues from what others around them are doing, and from what they feel they owe others. Social proof (“most people already do this”) and reciprocity (“help others the way you’d want to be helped”) are both extremely well-evidenced levers.

One of BIT’s own trials makes the point well. Working with the NHS, DVLA and Department of Health, BIT tested different messages encouraging people to join the Organ Donor Register at the exact point of renewing car tax online. The best-performing message wasn’t a statistic or a warning, it was a simple reciprocity appeal along the lines of “if you needed an organ transplant, would you have one?” BIT estimated that message alone was worth around 96,000 additional registrations a year compared with the control message – from a single line of copy.

The same request lands very differently depending on when it’s made. People weigh immediate effort far more heavily than future benefit, so prompting someone right after a relevant moment and right before a barrier appears makes action much more likely. The organ donor trial above illustrates this too: the prompt was deliberately placed at the moment someone was already online renewing their car tax, when joining the register could be completed immediately, rather than sent as a separate ask days later.

For local government, that might mean sending a bin-day reminder the evening before collection, or prompting a benefits renewal the moment a relevant change is reported, rather than in a generic quarterly mailout.

EAST and OASIS aren’t competing frameworks, they solve different problems. OASIS is the process for planning an entire campaign end-to-end: objectives, audience insight, strategy, implementation, evaluation. EAST is a lens you apply within that process, most naturally at the audience insight and strategy stage, to make sure whatever you’re asking people to do is actually realistic to act on. GCS’s own OASIS guidance points teams toward EAST specifically for larger-scale behaviour-change work.

If you haven’t already, it’s worth reading our guide to the OASIS framework alongside this one, together, they cover both how to plan a campaign and how to make sure people actually respond to it.

EAST won’t fix a campaign with the wrong objective or the wrong audience – that’s what OASIS is for. But once you know what you’re asking people to do, EAST is one of the fastest ways to work out why they aren’t doing it yet, and what to change: make it Easy, make it Attractive, make it Social, make it Timely.

Each part of EAST calls for a different kind of capability and most public sector comms teams are trying to deliver all four with tools that weren’t built for behaviour change at scale.

Orlo is the only AI optimised community engagement platform built specifically for the public sector. That means every tool in the platform maps directly to what public sector comms teams need to put EAST into practice, from a Unified Inbox that makes it easy for residents to get a response, to a Content Calendar that keeps every campaign looking attractive and consistent, to Social Listening and Trust Indicator data that shows what’s genuinely resonating, to scheduled, real-time publishing that gets the timing right.

Over 400 public sector organisations use Orlo to put frameworks like EAST into practice – including local government and central government, NHS trusts, housing associations, police forces, and fire and rescue services.

If you’re applying EAST to a live campaign and want to see how Orlo supports each principle in practice, a demo is the fastest way to see it in your context.
