Generating 445 enquiries with a targeted Christmas diagnostics campaign
Momenta Connect Diagnostics wanted to build awareness of its autism and ADHD assessment services and generate quality enquiries from parents and carers. Ambleglow created a Christmas campaign around a simple insight: changes in routine, social demands and sensory pressures can make the festive season a time when families notice more about how their child experiences the world. Running through December and into early January, paid social and Google Ads delivered 445 enquiry form requests and more than one million impressions.
The challenge
Momenta Diagnostics provides autism, ADHD and combined assessments for children and young people. Our brief was to reach parents of children aged 6 to 18 who may be considering whether their child could have undiagnosed autism or ADHD, nationally for online assessments and locally around Epsom, Isleworth and Chelsea in-clinic hubs.
Because this is a sensitive and personal decision, the campaign needed to reassure and inform rather than simply sell. Messaging had to recognise parents’ motivations – greater understanding, quicker access to support and clearer next steps – while acknowledging barriers including cost, timing and concerns around diagnosis.
The solution
We built the campaign around the message that Christmas can bring challenges, but it can also be the moment to take the first step towards understanding. Supporting messages focused on clarity, reassurance, early intervention and practical next steps, with lines including “You’re not alone” and “Make 2026 the year of understanding”.
The creative reflected experiences parents might recognise. We developed a range of Meta assets, including solus adverts and a short, emotive festive video. Facebook and Instagram were separated into dedicated ad groups, with national and geo-targeted audiences tested independently. Early testing showed short copy performed best on Facebook, emoji-led copy on Instagram and solus creative was the strongest format overall, allowing us to move the best-performing combinations forward.
Google Search and Display complemented Meta by reaching parents already looking for information around autism and ADHD assessments, signs and behaviours.

We were delighted with the results of our Christmas Diagnostics campaign.
Ambleglow really understood what we wanted to achieve and came up with some great ideas and content that brought it to life. They are always collaborative, easy to work with and just get what we’re trying to convey, which makes them a real extension of the team.
