Your sticker price is the entry ticket, not the total cost — and the gap between them can be 25% or more. If you're looking at a Honda generator, you're probably comparing model numbers and wattage. I've been buying and maintaining generators for a 40-person rental company for six years, and here's what actually moves the needle: remote start, oil filters, a decent battery charger, and knowing how to check fuel pump pressure without calling a mechanic at $80/hour.
For the Honda EU22i, the market price in the UK as of early 2025 is roughly £1,050–£1,200, depending on the dealer and whether remote start is bundled. That price tells you less than you'd think. The real question is what happens after you take delivery — and that's where most procurement budgets bleed out.
Why Listen to Me?
I'm a procurement manager for a mid-sized equipment rental company. We have about 40 employees, and I manage an annual budget of $180,000 for generators, parts, and maintenance. Over the last six years, I've negotiated with more than 15 vendors, tracked every invoice in our cost system, and logged at least 200 generator orders. I'm not a salesperson or a brand ambassador. I'm the guy who signs off on the POs and then gets the phone call when something breaks.
One thing I learned early: if you buy only on price, you'll lose. I've built a TCO spreadsheet that includes not just the unit cost, but the cost of extras, the cost of downtime, and the cost of vendor trust. It's not fancy — just a few columns in Excel. But it's saved us roughly $8,400 a year, simply by avoiding bad deals.
The Real Cost Breakdown of Buying a Honda Generator
Let's start with the numbers. A base Honda EU22i (also called the EU2200i in some markets) lists around £1,000–£1,100 in the UK. Remote start adds roughly £150–£200. A genuine Honda oil filter runs about £8–£12. A decent 12 amp battery charger will set you back £40–£60 if you buy it right — or £120 if you buy it wrong three times.
Here's what my spreadsheet taught me: on a typical Honda generator purchase, the unit price is about 75% of the total cost over three years. The other 25% hides in accessories, parts, and repair calls. That's why I don't get excited about a dealer who quotes £50 below market — I want to know if they stock genuine filters, whether they respond to small orders, and if they can help me when a fuel pump acts up.
Remote Start: A Luxury or a Requirement?
I went back and forth on remote start for months. On paper, it seemed like a luxury. Our customers rent generators for emergency backup and job sites. In an emergency, it's usually pouring rain or dark outside. You don't want to spend five minutes yanking a pull cord. After our first winter without remote start, we started adding it to every EU22i we bought. Customers notice. It's become a no-brainer for us.
But if you're using a generator as a permanent installation where you walk past it every day, remote start might not be worth the extra cost. I've seen plenty of contractors skip it without regret. The point is to think about your use case — for us, the remote start was a deal-maker.
Filters, Chargers, and the Stuff You Don't Think About
Don't Skimp on the Battery Charger
If your generator has an electric starter, you need a battery charger. We bought cheap 12 amp chargers first because they were half the price. They died after three months — one actually caught fire internally. Replace three cheap chargers and you've spent more than the cost of one quality unit. The surprise wasn't that cheap chargers fail; it was that the expensive charger is still running after four years. That's the cheapest maintenance decision we've made.
Oil Filters and the CAT 3126 Question
Our rental fleet is mostly Honda, but customers don't run only Honda equipment. We get requests for CAT 3126 oil filters more often than you'd think — from guys who own heavy machinery and just want one supplier for everything. When I first started, I told people, “We only sell Honda parts.” That was a mistake. Now we stock a small shelf of compatible filters for other brands, including the CAT 3126. Small orders like that don't make us rich, but they build trust. A customer who buys one CAT filter from us today is the same customer who rents our Honda EU22i next month.
That's the mindset I bring to every purchase: small doesn't mean unimportant. I've been on the other side — when I placed my first £200 order for filters, one supplier basically ignored me. The ones who treated us seriously are the same ones I now send $20,000 orders to. Don't forget that when you're negotiating with a dealer.
How to Check Fuel Pump Pressure (Without Calling a Mechanic)
This one could save you a service bill. If your generator is hard to start or stalls under load, the problem might not be the carburetor — it might be low fuel pressure. Here's how to check fuel pump pressure yourself:
- Get a fuel pressure gauge. One that reads 0–10 PSI is enough for most small engines; it costs about £30.
- Disconnect the fuel line between the pump and the carburetor (or from the fuel rail on larger models).
- Connect the gauge using an appropriate adapter. On Honda inverter generators, the fuel pump is often driven by the crankcase pressure, so the readings may pulse.
- Crank the engine and watch the gauge. Compare the reading to the spec in your owner's manual. Typically, you'll see 2–4 PSI for gravity-feed systems or 4–7 PSI for diaphragm pumps.
- If the pressure is below spec, the pump is likely weak. If it's erratic, check for a clogged fuel filter or a cracked line first.
I can't tell you the exact number for every Honda model because it varies, but the process is the same. I've caught a bad fuel pump before it turned into a “carburetor replacement” that would have cost four times more. The gauge pays for itself the first time.
The Surprising Hidden Cost: Vendor Attitude
The biggest hidden cost isn't a part or a service fee — it's the vendor who doesn't care about you. Back when we were placing small orders, one supplier quoted us £1,150 for a Honda EU22i, then didn't respond for two weeks when we asked about stock. Another quoted £1,220, but they picked up the phone, offered genuine advice about remote start, and shipped in two days.
I chose the second one. That's a £70 difference. Over three years, that vendor has saved us hundreds by helping us avoid wrong parts and by actually being available. If you're a small buyer, you don't need a vendor who makes you feel small. You need one who sees your potential.
What I'd Do Differently
Looking back, I should have ordered remote start from the start. I thought it was overkill — we're a rental company, and renters can pull a cord. I was wrong. We retrofitted remote start on a few units later, which cost more than if we'd just checked the box initially.
If I could redo that decision, I'd also standardize our battery chargers earlier. The cheap ones we bought caused two callbacks and a small fire risk. Given what I knew at the time — that “a charger is a charger” — it was a reasonable assumption. But the data disagreed.
When My Advice Might Not Apply
I'll be honest: my experience is based on a rental business in the UK and US, with about 200 generator orders under my belt. If you're a homeowner using a generator once a month for a campsite or occasional power outage, you might not need remote start or a heavy-duty 12 amp charger. My advice on TCO still applies, but your “hidden costs” will look different. And prices change — this was accurate as of Q1 2025. The generator market moves fast, so verify current rates before budgeting.
Also, I can't speak to every Honda model. The EU22i is my benchmark because it's the most popular unit we buy. If you're looking at an EU7000is or an industrial EB5000, the cost structures are different. Do the same total-cost exercise with your actual model numbers.
Here's the Bottom Line
Don't let a low quote hypnotize you. Ask about remote start, ask about genuine filters, ask about the vendor's willingness to stock a CAT 3126 filter even though you're a small account. The true cost of ownership is a combination of price, parts, and relationships.
Trust me on this one: a reliable supplier who treats small orders with respect is worth a 5–10% premium. A faulty fuel pump or a dead charger will cost you far more in downtime. And if you're deciding between two Honda generator packages, write your own spreadsheet. Factor in everything — then make the call.
