How EPRA sets prices

The Energy and Petroleum Regulatory Authority (EPRA) sets maximum retail pump prices for petrol, diesel, and kerosene in Kenya every month, effective from the 14th. Prices vary slightly by region (Nairobi, Mombasa, Eldoret, etc) reflecting inland transport cost. Stations cannot legally exceed the EPRA cap but can sell below.

Approximate consumption guide

  • Small saloon (1.3L petrol): 8 to 11 L/100km city, 6 to 8 L/100km highway
  • Medium SUV (2.0L petrol): 10 to 14 L/100km city
  • Large SUV (2.5L diesel): 9 to 12 L/100km city
  • Pickup (2.5L diesel): 10 to 14 L/100km loaded
  • Boda boda (motorcycle): 2 to 3 L/100km

Reducing fuel cost

  • Maintain tyre pressure at recommended PSI (drops 1 to 3% efficiency if low)
  • Service regularly (clean filters and plugs improve combustion)
  • Smooth driving, avoid hard acceleration and braking
  • Reduce idle time
  • Carpool or combine errands

Frequently asked

Do EPRA prices apply to all stations?

EPRA sets the maximum allowable retail price. Stations may sell below but not above. Most major stations sit at or just below the cap.

What if I use a different region?

Mombasa is typically KES 5 to 10 per litre cheaper than Nairobi (closer to the import port). Eldoret, Nakuru, Kisumu are 1 to 3 KES higher than Nairobi. Border counties higher still. Adjust the per-litre input to match your region's EPRA notice.

How often should I update the price?

Monthly. EPRA publishes the new prices around the 13th of each month. Update your figure when the new notice lands.
