Parts Ordering & Dispatch

Order spare parts from anywhere in Kenya — you do not need to travel to Nairobi

Send us your generator details and we will confirm the correct part, quote it, and arrange dispatch to your town. We also supply parts for projects across East Africa on a cross-border basis.

Dispatch options

Bus & matatu parcel services

The established way to move parts up-country quickly. Parcels are booked to the stage or depot nearest you.

G4S and Wells Fargo courier

Tracked courier options for higher-value items such as controllers, AVRs and electronic modules.

Regional & local courier networks

Regional operators and local parcel networks where they reach your town more directly.

Your own transporter

If you already use a transporter or have staff travelling to Nairobi, we can release the parts to them.

The channel used depends on the part, its value and where it is going, so we agree it with you per order and confirm the cost before anything is sent.

Confirmed orders are dispatched the same day. How quickly they reach you then depends on the transport chosen — commonly a day or two up-country. We will tell you which channel we are using and when the parcel has been sent, so you can track it from your end.

What to send us so we quote the right part

Generator parts vary between builds of the same model, so we verify compatibility from your serial number before quoting rather than assuming from the model name.

  • ✔Generator make and model (for example Cummins C55D5, Perkins 1104A)
  • ✔Engine and alternator serial numbers from the data plate
  • ✔The part number if you have it, or the old part
  • ✔Photographs of the part, the data plate and the controller display
  • ✔Any fault or error code currently showing
  • ✔The town or county the parts should be sent to

Availability: stock changes, and some items are brought in to order. We confirm availability and price against your enquiry before you commit to anything — we do not ask for payment on a part we have not confirmed.
