Lincolnshire Ambulance Service has been rewarded for its fast response times, less than a week after it was given a zero rating in performance tables.
The Health Minister, Rosie Winterton, says crews are reaching 75% of patients with serious or life-threatening conditions within eight minutes.
Her department has rewarded the service with a £40,000 cash grant.
Ambulance spokesman Noel Wade says it is good news for the service - and they already have plans for the money.
"The £40,000 will be invested in our Bracebridge Heath control centre.
"We've already had an award of £1.2m to completely modernise, refurbish and update the control centre.
