The service plans will be available in three tiers: critical, proactive and essential, guaranteeing response times of eight, 16 and 24 hours respectively.

The plans include parts, labour and travel costs as well as maintenance and one training seat for operator training.

Engineers will also carry a greater range of stock parts so more issues can be resolved on the first call out.

The plans are currently only available for US customers with plans to implement them in the UK later in the year.
