The British Flat Trainers Championship is the annual prize awarded to the season’s leading flat trainer. The title goes to the trainer who amasses the most prize money in British flat races, with the season running from 1 January to 31 December. This differs from the flat jockeys’ championship, which is determined by the number of winners. With the emphasis on prize money, the season’s Group 1 contests such as the Classics and those at the Royal Ascot Festival carry significant weight in determining the destination of the title.
Legendary trainers Sir Michael Stoute and Sir Henry Cecil each claimed 10 trainers’ championships during their careers but, as of 2026, top spot belongs to early 20th century trainer Alec Taylor, Jr., who won 12 championships between 1907 and 1925. Three Irish-based trainers have claimed the title, most notably the dominant force of the modern era, Aidan O’Brien.
2025 - Aidan O’Brien
Aidan O’Brien proved too strong in 2025 to claim an eighth British Trainers’ Championship. Lambourn and Minnie Hauk vaulted O’Brien into the lead with a Classic double at Epsom in June. Whirl (Nassau Stakes), Precise (Fillies’ Mile), and True Love (Cheveley Park Stakes) also made significant contributions, while Scandinavia added a Group 1 double in the Goodwood Cup and St. Leger Stakes.
John & Thady Gosden fared best of the British trainers to snatch second from Andrew Balding late in the year. Highlights of the season for the father-and-son training duo included Field Of Gold (St James’s Palace Stakes), Ombudsman (Prince of Wales’s Stakes), and Trawlerman (Gold Cup).
- 1st - Aidan O’Brien - £8,118,659
- 2nd - John & Thady Gosden - £7,375,503
- 3rd - Andrew Balding - £7,246,798
2024 - Aidan O’Brien
There was a seventh success for Aidan O’Brien in 2024 as the County Tipperary-based trainer ran away with the title. City Of Troy was the poster horse for the operation, bouncing back from Guineas disappointment to win the Epsom Derby, Coral-Eclipse, and Juddmonte International. O’Brien also enjoyed significant success in the staying division, with Kyprios winning the Gold Cup at Royal Ascot and Jan Brueghel claiming the St Leger.
A strong finish from Andrew Balding, headlined by Kalpana’s win in the Qipco British Champions Fillies’ & Mares Stakes, saw the Kingsclere handler fill the runner-up position for the second time. With wins in the 2,000 Guineas and Sussex Stakes, Notable Speech was the star turn for Charlie Appleby and Godolphin.
- 1st - Aidan O’Brien - £8,338,346
- 2nd - Andrew Balding - £5,143,845
- 3rd - Charlie Appleby - £4,354,104
2023 - John & Thady Gosden
2023 saw John Gosden win a sixth trainers' title and a first in partnership with his son Thady. A pair of fillies provided the platform for the Newmarket yard, with Emily Upjohn winning the Coronation Cup and Soul Sister claiming Classic success in the Oaks. The biggest single contributor was the revitalised five-year-old Mostahdaf, who picked up over £1 million courtesy of wins in the Prince of Wales’s Stakes and Juddmonte International.
Aidan O’Brien enjoyed his usual excellent campaign in second, with a Classic double in the Derby and St Leger, and Group 1 wins at Royal Ascot, the Qatar Goodwood Festival, and York Ebor Festival. Chaldean’s victory in the 2,000 Guineas was the clear highlight for third-placed Andrew Balding.
- 1st - John & Thady Gosden - £7,211,330
- 2nd - Aidan O’Brien - £6,456,282
- 3rd - Andrew Balding - £4,445,095
2022 - Charlie Appleby
Having won his first trainers’ championship in 2021, Godolphin number one Charlie Appleby edged ahead of William Haggas to defend his crown. In a year in which he claimed the English, Irish, and French 2,000 Guineas, Appleby also struck twice in Group 1 company at Royal Ascot with Coroebus (St James’s Palace Stakes) and Naval Crown (Platinum Jubilee Stakes).
William Haggas’s career-best runner-up finish was built on the success of the brilliant Baaeed. Carrying the famous Shadwell silks, the son of Sea The Stars won four successive Group 1s in the Lockinge Stakes, Queen Anne Stakes, Sussex Stakes, and Juddmonte International. The fillies Nashwa, Inspiral, and Emily Upjohn were the leading lights for the Gosdens.
- 1st - Charlie Appleby - £6,251,838
- 2nd - William Haggas - £5,818,203
- 3rd - John & Thady Gosden - £5,133,204
2021 - Charlie Appleby
It was a memorable year for Charlie Appleby, who finished on top of the table for the first time. Creative Force (British Champions Sprint Stakes) and Native Trail (Dewhurst Stakes) saw Appleby pull away in October, with Hurricane Lane (St Leger Stakes) also striking in Group 1 company. However, the star of the show for the boys in blue was Epsom Derby and King George VI and Queen Elizabeth Stakes hero Adayar.
Andrew Balding filled the runners-up position for the first time, largely thanks to his Coronation Stakes and Sussex Stakes-winning filly, Alcohol Free. Inspiral, Palace Pier, and Mishriff were the big money-spinners for the Gosdens, who finished just behind Balding in third.
- 1st - Charlie Appleby - £4,908,393
- 2nd - Andrew Balding - £4,354,981
- 3rd - John Gosden & Thady Gosden - £4,332,354
2020 - John Gosden
In his final full season before joining forces with his son Thady, John Gosden ended on a high with a fifth trainers' title. Lord North (Prince of Wales’s Stakes) and Stradivarius (Gold Cup) provided a Royal Ascot Group 1 double. The standout moment of the season came in July, when Enable won the King George VI and Queen Elizabeth Stakes for a record third time.
Aidan O’Brien finished second in a year negatively impacted by the global pandemic. The Ballydoyle handler peaked in June when Love and Serpentine completed a double in the behind-closed-doors editions of the Epsom Classics. Andrew Balding started the season in style when Kameko claimed the 2,000 Guineas but couldn’t quite keep pace with the Gosden operation.
- 1st - John Gosden - £3,087,945
- 2nd - Aidan O’Brien - £2,463,090
- 3rd - Andrew Balding - £2,113,942
2019 - John Gosden
2019 produced a closely fought battle between the powerhouse operations from either side of the Irish Sea. Flying out of the stalls with a Guineas double courtesy of Magna Grecia and Hermosa, Aidan O’Brien added the Epsom Derby with Anthony Van Dyck, Juddmonte International with Japan, and Champion Stakes with Magical. However, his impressive prize-money haul wasn’t quite enough to repel John Gosden.
The wonder mare Enable contributed over £1.3 million to the Gosden cause with wins in the Coral-Eclipse, King George VI and Queen Elizabeth Stakes, and Yorkshire Oaks. Other star names included Too Darn Hot and Stradivarius, while Anapurna and Logician provided Classic success in the Oaks and St Leger.
- 1st - John Gosden - £7,951,808
- 2nd - Aidan O’Brien - £7,686,578
- 3rd - Andrew Balding - £3,607,260
2018 - John Gosden
Starting well, with seven pattern-class wins in May, John Gosden hit full stride during the peak summer months, with six Group 1 victories between June and August. Holding the lead into the autumn months, he sealed the title with further top-level triumphs in the Dewhurst Stakes, Queen Elizabeth Stakes, and Champion Stakes. Cracksman, Too Darn Hot, and Roaring Lion all enjoyed productive campaigns. However, the pick of the bunch was staying sensation Stradivarius, who claimed the Yorkshire Cup, Gold Cup, Goodwood Cup, Lonsdale Cup, and British Champions Long Distance Cup.
Aidan O’Brien provided the biggest threat to Gosden, with Saxon Warrior (2,000 Guineas), Rhododendron (Lockinge Stakes), Forever Together (Oaks), and Merchant Navy (Diamond Jubilee Stakes), all striking in Group 1 company.
- 1st - John Gosden - £8,516,014
- 2nd - Aidan O’Brien - £6,279,555
- 3rd - Sir Michael Stoute - £4,575,897
2017 - Aidan O’Brien
Aidan O’Brien made a flying start to 2017 with Churchill and Winter supplying a Classic double at Newmarket. Wings Of Eagles caused a 40/1 shock in the Derby, while Highland Reel (Prince of Wales’s Stakes), Caravaggio (Commonwealth Cup), and Winter (Coronation Stakes) provided a Group 1 treble at Royal Ascot. With the title in safe keeping, O’Brien pulled further clear in the home straight, with seven more British Group 1 wins in September and October, including Capri in the St Leger Stakes.
John Gosden finished in a clear second in the year that Enable burst onto the scene with wins in the Oaks, Irish Oaks, King George VI and Queen Elizabeth Stakes, Yorkshire Oaks, and Prix de l’Arc de Triomphe.
- 1st - Aidan O’Brien - £8,335,028
- 2nd - John Gosden - £6,185,144
- 3rd - Sir Michael Stoute - £3,855,061
2016 - Aidan O’Brien
Aidan O’Brien ended his eight-year wait for a fifth British Trainers’ Championship with a dominant performance in 2016. Sired by the great Galileo, Minding picked up over £1.5 million in prize money, courtesy of her wins in the 1,000 Guineas, Oaks, Nassau Stakes, and Queen Elizabeth Stakes. Further standout performances came from Order of St George in the Gold Cup and Highland Reel in the King George VI and Queen Elizabeth Stakes.
2015 winner John Gosden finished well adrift of O’Brien but was still best of the rest.
Having slipped to second in 2015, the 2014 champion Richard Hannon Jr. dropped a further position to third.
- 1st - Aidan O’Brien - £8,130,756
- 2nd - John Gosden - £3,487,431
- 3rd - Richard Hannon Jr. - £2,809,779
