Stage V Generator Hire
NRMM Compliant Temporary Power
Stage V is the current emission standard for non-road mobile machinery (NRMM) in the UK and EU. For certain contracts and locations, hiring a Stage V-compliant generator is required, not optional.
Midas stocks Stage V machines across a range of sizes and can advise honestly on whether Stage V applies to your project.
What Is Stage V?
Stage V is the fifth and most stringent tier of the EU Non-Road Mobile Machinery emission regulations, now retained in UK law. It sets limits on particulate matter (PM), nitrogen oxides (NOx), and other exhaust pollutants from off-road diesel engines, including temporary hire generators.
The regulations are enforced in the UK by the Environment Agency and local authorities. In practice, Stage V generators are most commonly specified for:
- Government and public sector contracts
- Construction sites in Clean Air Zones or urban Low Emission Zones
- Projects with explicit NRMM management plans
- Events on council-owned or publicly managed land in Low Emissions Zones (LEZ)
- Contracts where the principal contractor requires emission compliance documentation
Midas Stage V Fleet
Our Stage V machines are available in the following sizes:
- 13kVA
- 20kVA
- 45kVA
- 60kVA
- 100kVA
- 150kVA
All units are sourced from JCB and Pramac and meet current Stage V particulate and NOx emission limits. Full compliance documentation is available on request.
- AdBlue top-up required on units above 60kVA - Midas includes AdBlue guidance and supply with all Stage V hires
- Load management matters - Stage V engines perform best under regular load. For applications with prolonged low- or no-load periods, speak to us so we can spec the right machine and operating regime. Running a Stage V engine on low loads can cause wet stacking and DPF issues.
- Higher hire cost - Stage V machines carry a premium over standard units due to the cost of compliance technology. This is standard across the industry.
- Compliance documentation provided - engine type approval certificates and NRMM registration available for your NRMM management plan
What Stage V Means in Practice
Stage V generators use diesel particulate filter (DPF) technology and, on units above 56kW, AdBlue (diesel exhaust fluid) injection to reduce NOx emissions.
There are a few things worth understanding before specifying a Stage V machine:
Do You Need Stage V for Your Project?
Not every generator hire requires a Stage V machine. If your project does not have an NRMM management plan, is not in a designated Clean Air Zone, and has no specific emission compliance requirement in the contract, a standard diesel generator may be entirely appropriate and will cost less to hire.
We will always give you a straight answer on this. If Stage V is not required for your application, we will tell you and hire you the right machine at the right price.
Frequently Asked Questions
Is Stage V mandatory for all generator hires?
No. Stage V is required when a contract, site or local authority specifies NRMM emission compliance. For most private-sector hires, standard machines remain appropriate. If your tender documents mention NRMM or Clean Air Zones, call us to discuss.
What is AdBlue and do I need to supply it?
AdBlue is a diesel exhaust fluid used in Stage V machines above 56kW to reduce NOx emissions. Midas supplies AdBlue with Stage V hires and can include scheduled top-ups as part of a fuel management package.
Can you provide compliance documentation for my NRMM management plan?
Yes. We can provide engine type approval documentation for all Stage V machines on our fleet.
What if I only need a Stage V machine for part of my contract?
We can arrange Stage V hire for the duration you require, even if the wider project uses standard machines. Speak to us about mixed fleet options.
