Greengear 5kW LPG Generator: A Popular Choice for Clean Power in Mobile Catering
The Greengear GE-5000UK is a dedicated LPG/propane generator delivering 5.0kW rated output from a clean-burning fuel source. Popular with mobile caterers who want single-fuel simplicity, lower emissions, and reliable power for coffee vans, burger units, and event setups. Electric start, 93 kg, runs on standard 37 mbar propane — the same bottles you already use for your cooking equipment.
Why a Dedicated LPG Generator Makes Sense for Mobile Catering
Most generators on the market are either petrol-only or dual fuel (petrol with an LPG conversion kit bolted on). The Greengear GE-5000UK is different — it’s engineered from the ground up to run on LPG/propane and nothing else.
For mobile caterers, that’s a genuine advantage. You’re already carrying propane for your cooking equipment, so running your generator on the same fuel means one gas type, one supplier, and no jerry cans of petrol sloshing around in your van. It also means cleaner exhaust — LPG produces significantly less carbon monoxide and particulate matter than petrol, which matters when you’re trading at indoor markets, covered pitches, or events where environmental compliance is tightening.
Local councils and event organisers are increasingly specifying low-emission power sources. A dedicated LPG generator gives you a straightforward answer when they ask what fuel you’re using.

What Can a 5kW Generator Actually Power?
The GE-5000UK delivers 5.0kW of continuous rated power. That’s enough for most single-trader mobile catering setups, but you need to understand your actual load before committing:
| Equipment | Typical Wattage | % of 5.0kW Rated |
|---|---|---|
| Fracino Cherub espresso machine | 2,000W | 40% |
| Commercial fridge (undercounter) | 150W | 3% |
| Coffee grinder | 350W | 7% |
| LED lighting strip | 50W | 1% |
| Coffee van total | 2,550W | 51% |
| Parry LPG griddle (electric ignition only) | 50W | 1% |
| Commercial deep fryer (electric) | 2,500W | 50% |
| Bain marie (electric) | 1,200W | 24% |
| Extraction fan | 200W | 4% |
| Burger van total (mixed LPG/electric) | 1,500–3,300W | 30–66% |
The golden rule: keep your running load below 80% of rated output (4.0kW) for reliable, long-life operation. Short-term spikes from motor startups are fine — the 5.5kW max output handles those — but sustained load should sit comfortably within the 5.0kW rated figure.
If your setup regularly exceeds 4kW, look at the Gorilla Power GP5500E-DF (4.5kW rated) or the GP8000iE (7.0kW rated) instead.
LPG Running Costs — What Will It Actually Cost You Per Day?
The Greengear manual lists consumption at 398 g/kWh. Here’s what that means in real money at different load levels, based on propane costing approximately £1.20 per kg from a standard 47 kg bottle:
| Load Level | Power Output | LPG per Hour | Cost per Hour | 8-Hour Day | 47 kg Bottle Lasts |
|---|---|---|---|---|---|
| 50% load | 2.5kW | ~1.0 kg | ~£1.20 | ~£9.60 | ~47 hours |
| 75% load | 3.75kW | ~1.5 kg | ~£1.80 | ~£14.40 | ~31 hours |
| Full rated (100%) | 5.0kW | ~2.0 kg | ~£2.40 | ~£19.20 | ~24 hours |
Most mobile caterers run at 50–75% load during a typical trading day. At 75% load, you’re looking at roughly £14–£15 per day in fuel — comfortably within the margins of a decent trading pitch. A single 47 kg propane bottle gives you about 4 full trading days before you need a swap.
Clean Power and Environmental Compliance
LPG generators produce measurably lower emissions than their petrol equivalents. Carbon monoxide output is reduced by around 25–30%, and there’s virtually no particulate matter in the exhaust. For mobile caterers, this has three practical benefits:
Event access: An increasing number of festivals, markets, and council-run events now specify low-emission power sources in their trader terms. An LPG generator ticks that box without the cost of a battery/inverter hybrid system.
Indoor and covered trading: While you should never run any generator in an enclosed space, LPG exhaust is cleaner when trading under canopies, in semi-covered market halls, or near building entrances where ventilation is limited.
Single fuel simplicity: No petrol to store, no spillage risk, no fuel going stale over winter. Your propane bottles sit safely in the gas locker alongside your cooking supply. One fuel type, one storage solution, one supplier.
Noise Levels and Neighbour Relations
The Greengear GE-5000UK is an open-frame generator, so it won’t be whisper-quiet. Open-frame generators in the 5kW class typically produce 70–75 dB(A) at 7 metres — roughly the volume of a busy road or a vacuum cleaner.
If noise is a primary concern (residential pitches, early morning markets, wedding catering), consider an inverter generator like the Gorilla Power GP3500i at around 59 dB(A), or the larger GP5000i. Inverter models are significantly quieter but cost more and typically deliver less peak power.
For most street food pitches, market stalls, and outdoor events, the Greengear’s noise level is perfectly acceptable. Position it downwind of your serving hatch and as far from customers as your gas hose allows.
How the Greengear Compares to Other Mobile Catering Generators
The UK mobile catering generator market has a handful of serious contenders. Here’s how the Greengear GE-5000UK stacks up:
| Generator | Fuel | Rated kW | Type | Weight | Best For |
|---|---|---|---|---|---|
| Greengear GE-5000UK | LPG only | 5.0kW | Open frame | 93 kg | Clean power, single fuel |
| GP2000i | Petrol | 1.6kW | Inverter | 22 kg | Low-power, quiet jobs |
| GP3500i | Petrol | 3.0kW | Inverter | 30 kg | Coffee vans, quiet pitches |
| GP3800iE | Petrol | 3.2kW | Inverter | 35 kg | Mid-range, electric start |
| GP5000i | Petrol | 4.2kW | Open frame inverter | 47 kg | Higher loads, cleaner power |
| GP5500E-DF | Dual fuel | 4.5kW | Open frame | 85 kg | Flexibility, high output |
| GP8000iE | Petrol | 7.0kW | Inverter | 90 kg | Large setups, events |
| GP12800DE | Diesel | 10.0kW | Open frame | 170 kg | Multi-unit, heavy commercial |
The Greengear occupies a unique position — it’s the only dedicated LPG generator in the lineup. If clean fuel compliance or single-fuel convenience is your priority, it’s the obvious choice. If you need quieter operation or more raw power, look at the inverter models or the GP5500E-DF dual fuel.
Setting Up and Maintaining Your Greengear Generator
The GE-5000UK runs on standard UK propane at 37 mbar regulator pressure (the LPG inlet accepts 1.0–2.5 BAR). Connect it to your propane supply using a proper POL fitting and appropriately rated hose.
First use checklist:
- Fill the engine with 1.1 litres of 10W-30 or 10W-40 4-stroke oil (check the dipstick)
- Connect to a propane bottle with a clean, tested regulator and hose
- Open the gas valve, set the choke, and use the electric start button
- Let the engine warm up for 2–3 minutes before applying any load
- Gradually increase load — don’t plug everything in at once
Ongoing maintenance schedule:
| Interval | Task |
|---|---|
| Every use | Check oil level, inspect gas hose and connections for leaks |
| Every 50 hours | Change engine oil (1.1L capacity) |
| Every 100 hours | Clean or replace air filter element |
| Every 200 hours | Replace spark plug, inspect valve clearances |
| Annually | Full service — oil, filter, spark plug, gas system leak test |
| Before storage | Run engine dry, disconnect gas, top up oil, store in dry location |
The generator operates in ambient temperatures from -5°C to 40°C, which covers every realistic UK trading scenario from winter Christmas markets to summer festivals.
Safety Equipment You’ll Need Alongside the Generator
A generator on its own isn’t enough. To trade legally and safely, you’ll also need:
- RCD (residual current device) — a 30mA portable RCD between the generator and your equipment. Non-negotiable for any commercial electrical supply.
- Proper cabling — outdoor-rated, appropriately fused extension leads. No domestic multi-socket strips.
- Gas leak detector — check every connection before starting up. Soapy water works; a gas detector pen is better.
- Fire extinguisher — dry powder, positioned within reach of both the generator and your cooking equipment.
- Earth rod — some event organisers and electrical inspectors require an earthing stake. Carry one even if it’s not always needed.

Frequently Asked Questions
What engine does the Greengear GE-5000UK use?
The GE-5000UK uses a GG4GN engine — a Greengear-designed OHV single-cylinder 4-stroke with 389cc displacement. It’s purpose-built for LPG/propane fuel and uses ENERKIT BASIC gas technology. This is not a converted petrol engine with an aftermarket kit; it’s designed from the factory to run on propane.
How much LPG does the Greengear 5kW generator use per hour?
Consumption is rated at 398 g/kWh. At typical mobile catering loads (75% of rated output), that works out to approximately 1.5 kg of propane per hour, costing around £1.80 per hour. A standard 47 kg propane bottle will last roughly 31 hours of trading at this load level — about 4 full trading days.
Can the Greengear GE-5000UK run a coffee machine?
Yes. A typical espresso machine like the Fracino Cherub draws around 2,000W. That’s 40% of the GE-5000UK’s 5.0kW rated output, leaving plenty of headroom for a grinder (350W), fridge (150W), and lighting. A full coffee van setup typically uses 2,500–3,000W — well within the generator’s comfortable operating range.
Is the Greengear GE-5000UK a dual fuel generator?
No. The Greengear GE-5000UK is a dedicated LPG/propane generator. It does not run on petrol. The engine and fuel system are specifically designed for LPG operation using ENERKIT BASIC technology. If you need dual fuel flexibility (petrol and LPG), look at the Gorilla Power GP5500E-DF instead.
How heavy is the Greengear 5kW generator?
The GE-5000UK weighs 93 kg (205 lbs) with overall dimensions of 700 x 570 x 500 mm. It has built-in wheels and a folding handle for moving it around on flat ground, but you’ll want two people to lift it in and out of a van. It’s heavier than most petrol inverter generators in this power range, but comparable to other open-frame models.
What propane regulator do I need for the Greengear generator?
The GE-5000UK accepts LPG inlet pressure between 1.0 and 2.5 BAR. A standard UK 37 mbar propane regulator with a POL fitting will work — the same type you’d use for any commercial LPG cooking appliance. Use a proper commercial-grade hose rated for LPG, and always leak-test every connection before starting the generator.
Is the Greengear generator quiet enough for markets and events?
The GE-5000UK is an open-frame generator, so it’s not as quiet as an inverter model. Open-frame 5kW generators typically produce 70–75 dB(A) at 7 metres. That’s acceptable for most outdoor markets and events, but if you’re trading at noise-sensitive pitches (residential areas, weddings, indoor markets), an inverter generator like the GP3500i at around 59 dB(A) would be a better choice.
