Brant Dunshea, acting chief executive of the BHA, said: “Of course the BHA is disappointed this work hasn’t been concluded more quickly.
“But in saying that we have got to acknowledge and recognise those financial headwinds and competing capital investment expectations that the industry is placing on racecourses.”
Dunshea added the BHA are “committed to working collaboratively with the racecourses and the PJA to get the work done” and there are “interim measures that racecourses must commit to” until the work is completed.
Leicester Racecourse was the first course to meet the targets, opening its refurbished weighing room in December 2023.
The PJA said: “Those courses that have completed their works deserve praise, particularly small independent racecourses such as Fakenham, Leicester, Pontefract, Ripon and Taunton.”
The Newmarket July course is the only racecourse that holds a major racing festival to have met the targets, with Cheltenham and Aintree among those not to have done so.
In 2021, retired Grade One-winning jockey Lizzie Kelly told the Daily Mail: “The physical layout of many weighing rooms can lead a young female jockey into potentially uncomfortable situations. That is a massive issue and needs to be addressed urgently.
“Can you imagine the uproar if Emma Raducanu had to go into the men’s changing room before a match at Wimbledon?”
The BHA said progress had been slowed by “planning and building restrictions and the availability of useable space”, adding that some weighing rooms are listed buildings and others are built on or near floodplains.
However, it said: “The onus is on everyone with a stake in this project to now make this a reality across the country. It’s what our participants deserve and what British racing expects.”
