A dated guide to what's on in Sevenoaks in June 2026: the Summer Festival, Three Arts Festival, Great Big Green Week at Knole, the Stag, and the weekly markets, with venues, dates and what we could confirm on prices.

If you are looking for what’s on in Sevenoaks this month, June 2026 is one of the fuller stretches in the local calendar. The Sevenoaks Summer Festival is running across the town, the Three Arts Festival brings young musicians to Walthamstow Hall, the national Great Big Green Week lands on Knole’s doorstep from 6 to 14 June, and the weekly markets carry on as usual. Here is a dated rundown, with venues and the prices we could confirm against each organiser’s own listings.

Where a price is not shown, it is because the venue had not published one at the time of writing. We have linked every source so you can check before you set off, because times and tickets can change.

Sevenoaks Summer Festival: town-wide, all summer

The Sevenoaks Summer Festival frames the season. Its own calendar lists community events running between 1 June and 31 August 2026, a mix of music, drama, heritage and talks at venues across the town, some ticketed and some drop-in (Sevenoaks Summer Festival).

Confirmed June dates on the festival calendar include:

  • Musica Poetica, Saturday 7 June, 7:30pm, at St Luke’s Church (ticketed).
  • Free Youth Jazz Workshop, Tuesday 23 June, 7:00pm, at the Stag Plaza, listed as a free event.
  • West End Musicals, Saturday 27 June, 7:30pm, at the Stag Theatre (ticketed).

The festival points visitors to its online programme for the full schedule, noting that some events need advance booking while others are turn-up-on-the-day (Sevenoaks Town Council).

Sevenoaks Three Arts Festival: young performers at Walthamstow Hall

The Sevenoaks Three Arts Festival is a competitive performing arts festival, and in 2026 it runs over two weekends in June at Walthamstow Hall Senior School: Saturday 13, Sunday 14, Saturday 20 and Sunday 21 June. Classes cover Speech and Drama, Piano, Singing including choirs, Woodwind and Brass including orchestras, Strings and Accordions (Sevenoaks Three Arts Festival).

The season closes with the Cup Winners’ Concert on Saturday 27 June 2026, when the weekend’s top performers play together. The festival is affiliated to the British and International Federation of Festivals (Federation of Festivals).

What it means for you: this is one of the more affordable family outings of the month, a chance to hear local children and teenagers perform across a wide range of disciplines. The organiser’s website is the place to confirm session details and admission.

Knole and Great Big Green Week: 6 to 14 June

Knole sits on the edge of the town and has a packed June diary. The national Great Big Green Week runs from 6 to 14 June 2026, organised by The Climate Coalition under the theme “Together for Good” (Great Big Green Week), and Knole is marking it with two free-to-join walks:

  • Park walk and litter pick, Saturday 13 June, 11:00am to 11:45am.
  • Nature park walk, Sunday 14 June, 2:00pm to 2:45pm.

Both appear on the Knole events listing (National Trust).

Other June dates at Knole from the same listing:

  • Powerhouse: 20 Historical Women Who Changed the World, an exhibition of portraits by artist Chinwe Russell shown in the historic showrooms, running 6 June to 31 July, 10:00am to 5:00pm.
  • Attic tours, behind-the-scenes tours of the roof spaces, running from 10 June through the autumn, 11:30am to 12:15pm.
  • The changing faces of Knole: an archaeology walk, from 18 June, 11:30am to 12:15pm.
  • Toddler Mondays at Knole, babyccino coffee mornings and storytime, from 8 June, 10:00am to 12:00pm.
  • Book Club at Knole, Thursday 25 June, 6:00pm to 7:15pm.

The National Trust says tickets for Knole can be booked online up to an hour before a visit, subject to availability, or by phone on 0344 249 1895 (National Trust). Prices for individual events were not published on the listing at the time of writing, so check each event’s own page before booking.

The Stag: theatre, cinema and festival nights

The Stag, the town’s 448-seat community arts centre on London Road, is one of the festival’s host venues this month and runs its own cinema and live programme year round (Stag Theatre). As noted above, it hosts the free Youth Jazz Workshop on 23 June and West End Musicals on 27 June as part of the Summer Festival.

Looking just beyond the month, the Stag’s published concert diary lists Corazon: The Heart and Soul of Santana on Friday 10 July 2026, a tribute show, if you want to plan ahead (Songkick). For the full film and live listings, the Stag’s own site is the most reliable source, as third-party ticket aggregators were not carrying its June programme in full when we checked.

The weekly markets

If you would rather just wander, Sevenoaks has three regular markets, all confirmed by the town council (Sevenoaks Town Council):

  • Bligh’s Saturday Market, Bligh’s Meadow, 9:00am to 4:00pm every Saturday, with artisan and handmade goods, ceramics, candles and speciality foods.
  • High Street Saturday Market, on the Upper High Street outside the Chequers, 9:00am to 4:00pm, with fresh produce, breads, olives, fruit, vegetables and flowers.
  • Wednesday High Street Market, on the High Street outside the Chequers, 8:00am to 2:00pm.

These run weekly, so any Saturday or Wednesday in June fits.

What it means for you

The practical takeaway: June clusters most of the town’s activity into two weekends. The 13 to 14 June weekend gives you the Three Arts Festival, the Great Big Green Week walks at Knole and a market on both days. The 20 to 21 and 27 June dates add more festival performances and the Cup Winners’ Concert. If you are coming from outside Sevenoaks, plan parking and train times around those Saturdays, when the high street is busiest.

Because organisers update listings through the season, treat the dates above as confirmed at the time of writing and use the linked sources to check anything before you travel.
