The biggest challenge GB1 face is Germany, who spend about £2m a year on research and development alone.
In comparison, British Bobsleigh received £120,000 from UK Sport before Beijing.
For the Milan 2026 cycle, they have been awarded £2.8m after a £900,000 uplift in August 2023.
Despite this increase, Gulliver says they want their wages to rise in line with inflation.
“It’s performance based – we have consistent medals coming in at championships,” he said.
“We always want more funding – we know it will bring us better equipment. It’s on us as the athletes to get those results.
“One of the issues we’ve been speaking about recently in the athletes’ sphere is the performance awards, the money that comes directly to us, that supplement our wages and help us train full-time.
“They haven’t changed for a long time now and an increase in them would be great,” added Gulliver, who remains grateful for the current funding from UK Sport.
The money helped Greenwood, 27, quit his full-time job and focus on bobsleigh.
“I was working a full-time job, doing a 60-hour week and night shifts. One time I finished at 3am and then had to be on the track for 8am. It was tough,” he said.
“We do get a little bit of funding and I’m grateful – it allowed me to leave my full-time job. If they want us to win that gold medal, that has to happen.”
