KotlinLeeds is a non-profit, community-run conference for Android, Kotlin and Kotlin Multiplatform developers, described by its organisers as the first dedicated Kotlin conference in the United Kingdom. Founded in 2025 by Adam Rush, it is the Android counterpart to the established SwiftLeeds conference and shares its focus on an affordable, friendly event outside London. The 2026 edition runs over two days, 15–16 October, at the Leeds Playhouse in the centre of Leeds. The venue sits about fifteen minutes' walk from Leeds railway station and a short drive from Leeds Bradford Airport, making it accessible for attendees travelling from across the UK and Europe. Talks cover Android app development, Kotlin Multiplatform for sharing code across mobile and desktop, and backend engineering with Kotlin on the JVM. The conference is pitched at a wide range of experience levels, from developers new to Kotlin to enterprise architects, and the speaker line-up draws on both tooling vendors and companies shipping Kotlin in production. Student pricing and group discounts help keep the event open to the community it serves. For the UK Kotlin community, KotlinLeeds fills a long-standing gap in the conference calendar.
KotlinLeeds 2026 takes place October 15–16, 2026 in Leeds, United Kingdom.
KotlinLeeds 2026 is an in-person event.

Mid-October in Leeds means proper northern autumn: short daylight, a decent chance of rain, and a city centre that compensates with covered Victorian arcades and a dense concentration of pubs. The conference sits within a compact core where almost everything is walkable, and Leeds has become one of the UK's larger technology employment centres outside London, which shows in the local developer community.
Leeds Bradford Airport (LBA) is around 30 to 40 minutes from the centre by bus or taxi, with mainly European and domestic routes. Manchester Airport (MAN) offers far wider long-haul choice and connects by direct train in roughly 90 minutes. Leeds railway station is one of the busiest outside London, with frequent direct services from London King's Cross taking a little over two hours.

UK mobile coverage across central Leeds is dependable on all major networks, including on trains along the East Coast route. Travellers arriving from outside the UK will find an eSIM the least troublesome way to get connected before leaving the airport. Set up an eSIM with Airalo before you board and you're online the moment you land.
Leeds Art Gallery and Henry Moore Institute. Adjacent buildings on The Headrow holding a strong collection of British twentieth-century art and a dedicated sculpture research centre. Both are free and centrally placed, making them an easy filler between conference sessions. Ninety minutes covers the pair comfortably.
Victoria Quarter and Kirkgate Market. Restored Victorian shopping arcades with mosaic floors and stained glass sit a few minutes from the covered market where Marks & Spencer began. The contrast between the two is the point. Useful in October, since both are entirely under cover.
Royal Armouries Museum. On the waterfront at Leeds Dock, this national collection of arms and armour spans several floors and is free to enter. The riverside walk from the centre takes about twenty minutes. Allow two hours, longer if live demonstrations are scheduled.
Ilkley Moor and the Dales. Regional trains reach Ilkley in around 30 minutes, putting open moorland within easy reach for a half-day walk. The Yorkshire Dales proper are further but accessible by car. Autumn conditions demand waterproofs and boots rather than trainers.
Which airport is best for Leeds?
Leeds Bradford (LBA) is closest at 30 to 40 minutes from the centre, but Manchester (MAN) has far more international routes and a direct train of about 90 minutes.
What should I pack for mid-October?
Expect cool, changeable weather with a real chance of rain. A waterproof jacket and layers are more practical than an umbrella in exposed conditions.
Is Leeds walkable?
Yes. The city centre, station and main venues sit within a compact area, and most conference visitors will not need public transport during the day.
