The announcement was made on social media earlier this morning (Tuesday November 30).
The event will be a celebration of those who have supported their communities since the outbreak of COVID.
And guests will include people who have experienced loneliness or bereavement during the pandemic.
When is the Kate and William carol service?
The carol service will take place on Wednesday December 8. It is expected to air on TV in the days before Christmas.
Themes concerning mental health, supporting families and the Early Years royal foundation are expected to feature.
What did Kate and William announce?
An Instagram post showed a formal invite on letter-headed paper and tucked into an envelope.
The caption explained: “This Christmas we are celebrating the incredible work of individuals and organisations across the nation who go above and beyond to support their communities.
“Next week, The Duchess will host a Christmas carol service at Westminster Abbey, supported by The Royal Foundation, bringing many of those inspirational people together.
Something we can all look forward too, thank you.
“The service, which will be broadcast in December, will look back on the last eighteen months. To think not only of the unprecedented challenges that we have all faced as we continue to navigate the COVID-19 pandemic, but also to remember the positives.
“People and organisations pulling together in their communities, the small acts of kindness across different demographics and generations, and the unsung heroes who stepped up to help others.”
