Fixed-price diagnostics before generator servicing

We offer a one-off fixed-price service for all diesel or petrol generators up to 275 kVA, providing exceptional value for money. An expert engineer will visit you to assess the condition of your generator and carry out a comprehensive diagnostic inspection for a fixed fee of EUR 120 + VAT + travel expenses.

Replacement generators during repair or servicing

To provide backup power if your generator breaks down, we have several generators of up to 275 kVA available for hire. To meet the SLAs of our maintenance contracts, we use our own lorry with a lift, which allows us to deliver a replacement generator from stock in an exceptionally short time.
