How to Pay for Insulation in Boulder County: ClearPath On-Bill, RENU, and What Actually Fits Your Situation

Most people who call us about insulation already know they need it. They’ve got a bedroom over the garage that never gets warm. They’ve got ice dams every February. They’ve been in the crawl space once and would prefer never to go back.

What stops the project isn’t doubt about whether it works. It’s that an average attic job in Boulder County runs about $2,500, a spray foam project typically lands between $4,500 and $5,000, and that money has to come from somewhere in a month that already has a car repair in it.

So the actual question is rarely “should I insulate.” It’s “how do I pay for this without wrecking the next three months.”

There are three answers in Colorado right now, and they’re genuinely different from each other. One of them is new enough that most homeowners have never heard of it, and most contractors aren’t set up to offer it yet.

The short version

ClearPath On-Bill — You pay nothing upfront. The cost of the work is added to your Xcel Energy bill as a monthly line item. No credit check. Only available if Xcel provides your electricity.

The Colorado RENU Loan — A real loan through a Colorado credit union, backed by the state. Available statewide regardless of who your utility is. Longer terms available. Requires a credit check.

Conventional home improvement financing — A lender network that shops your application across multiple lenders. Fastest option, widest eligibility, and the fallback when the program-based options don’t fit.

We’re set up to do all three. Below is how each one actually works and, more usefully, how to tell which one is yours.

ClearPath On-Bill: the new one

ClearPath On-Bill is a repayment program administered by the Collective Clean Energy Fund (CCEF) in partnership with Xcel Energy. It’s structured differently from anything else on this list.

Here’s the mechanic. You get a quote. CCEF pays us the full cost of the installation upfront. You repay that amount over time as a line item on your monthly Xcel bill. There’s no separate loan account, no second bill to remember, and no new payment method to set up.

According to CCEF’s published program materials:

Amount: up to $50,000 per meter
Rates: between 4.5% and 5.49%
Term: up to 10 years
Down payment: none

Rates and terms are set by CCEF, not by us, and they can change. Confirm current terms at ccef.info/on-bill before you make a decision.

What can be financed includes air sealing and insulation, which is the reason we’re writing this. It also covers electric water heating, air-source and ground-source heat pumps, battery storage, and windows and doors. If you’re planning more than one upgrade, they can go on a single project.

Who qualifies: you need to own the home and be the person named on the utility bill. There are additional eligibility criteria published on CCEF’s site.

Who doesn’t: two groups are excluded at this time. Gas-only Xcel customers — you need electric service from Xcel, not just gas. And households below 80% of Area Median Income.

That second one surprises people, so it’s worth explaining, because it isn’t what it looks like.

If you’re below 80% AMI, you’re not being turned away — you’re being pointed somewhere better

ClearPath is a repayment program. You get the work now and pay for it over time on your utility bill. That’s a sensible deal for a lot of households, but it’s a worse deal than not paying for the work at all — and for income-qualified Colorado households, programs exist that cover weatherization at no cost.

So the 80% AMI floor isn’t a wall. It’s a fork in the road, and the other branch is better.

If your household income is below 80% of the area median for your county, these are the programs to look at first:

Colorado’s Weatherization Assistance Program (WAP), run through the Colorado Energy Office, provides no-cost weatherization — insulation and air sealing included — to income-qualified residents. Eligibility is determined by county, household size, and income. Availability depends on funding and there can be a waiting list, so apply early rather than in January.
Xcel Energy’s Income-Qualified Weatherization program offers free efficiency improvements to qualifying Xcel customers.
Energy Outreach Colorado’s CARE program covers air sealing, insulation, HVAC, energy audits, and contractor management for households meeting the 80% AMI threshold for their county.
The Colorado Energy Savings Navigator is a free state-run tool that will tell you which programs you qualify for without calling five different agencies.

We’re not going to publish an income table here, because the limits change annually and vary by household size and county. Use the state’s own eligibility chart or the Navigator — those are always current.

And we’ll say the obvious thing plainly: if you qualify for one of these, take it. Free work beats financed work every time. Call us if you want a second opinion on scope, but don’t finance something the state will pay for.

The part worth slowing down for

Because these upgrades cut what your home uses, the monthly savings frequently run higher than the monthly repayment. CCEF’s own materials make this point: the bill goes up by the repayment amount and down by the savings, and for a lot of homes the net favors the homeowner from the first month.

We want to be careful here, because that’s a claim you should hold us to and not every home lands the same way. A 1962 ranch in Gunbarrel with four inches of settled fiberglass and no air sealing is going to see a very different number than a 2015 build that’s already reasonably tight. We won’t project a monthly savings figure for your house without having been in your attic.

But the structural point is real, and it’s what makes on-bill different from a loan. You aren’t borrowing against your house. There’s no lien on your home, and the obligation is tied to the meter.

The Colorado RENU Loan

RENU is the older and better-established of the two state-backed options. It’s a statewide residential loan program sponsored through the Colorado Energy Office and the Collective Clean Energy Fund, offered in partnership with Colorado credit unions.

Where it differs from ClearPath:

It’s available statewide, regardless of utility. If you’re in a co-op territory, on a municipal utility, or anywhere Xcel doesn’t provide your electricity, RENU is still on the table.
Longer terms are available — RENU goes well beyond ClearPath’s 10-year ceiling.
Higher project cap.
It requires a credit check, because it’s an actual loan through a credit union.
It’s secured by the equipment installed, not by your home.

Projects have to be completed by an authorized RENU contractor. We are one.

RENU is the right answer for a meaningful share of our service area. Boulder County has plenty of homes outside Xcel electric territory, and for those homeowners ClearPath simply isn’t available.

Conventional home improvement financing

Both of the above are program-based, which means both come with eligibility rules — utility territory, account standing, ownership, measure eligibility.

Sometimes none of it fits. The house is a rental you don’t live in. You’re not the name on the utility bill. The scope includes work that isn’t on the eligible measures list. Or you just want the money this week and don’t want to wait on a program approval.

Through our own financing partners, we can put you in front of a lender network that shops a single application across multiple lenders — soft credit pull available, quick pre-approval, and funding in a matter of days rather than weeks.

We’re deliberately not printing rates or payment figures for this option, because the offers you’ll see depend on your own credit profile and the lending partner. You’ll see your actual numbers before you commit to anything. What we’ll say is that it’s the most flexible path and the fastest one, and it’s the answer when the program options run out of road. Ask us and we’ll send you the details.

One sequencing note

If there’s a rebate available on your project, it should be applied first, to reduce the cost — and then you finance whatever remains. CCEF’s program materials confirm that rebates available at the time of installation can be applied to reduce the financed amount. Ask us what’s active the week you’re deciding, because these programs change.

Which one is yours

Xcel provides your electricity, you own the home, and your name is on the bill. Start with ClearPath. Nothing down, no credit check, and the repayment rides on a bill you’re already paying. This is the lowest-friction path that exists for insulation work in Colorado right now.

Xcel doesn’t provide your electricity, or you’re outside their territory. RENU. Statewide availability is the whole point of the program, and insulation is squarely a covered measure.

You want a longer term than ten years, or the project is larger than the on-bill cap. RENU. The longer amortization and higher cap exist for exactly this.

Your household income is below 80% of the area median for your county. Don’t finance anything yet. Check WAP, Xcel’s Income-Qualified Weatherization program, and Energy Outreach Colorado first — there’s a real chance the work gets done at no cost to you. Start with the Colorado Energy Savings Navigator.

It’s a rental, you’re not the account holder, or the scope doesn’t fit the eligible measures list. Conventional home improvement financing. Ask us and we’ll walk you through the options.

You want it done this week. Conventional financing. Program approvals aren’t slow, but a lender network is faster.

You’re doing insulation now and something else later. Talk to us before you pick. Both state-backed programs cover multiple measure types, and how you sequence the work can affect what you’re eligible for. That’s worth a fifteen-minute conversation and it’s free.

What the process actually looks like with us

We’ll be honest that this is less involved than people expect.

We come out and quote the work. Nothing about financing changes how we scope a job or what we charge. The price is the price.
We tell you which programs you’re eligible for and which one we’d pick if it were our house.
You apply. For ClearPath, we send you the link and you complete the application yourself — it takes under two minutes if you have an Xcel bill or statement in front of you. If you’d rather not do it alone, we’ll walk through it with you on the phone or at the kitchen table.
On approval, you complete the program agreement.
We install. CCEF pays us directly.
Repayment starts on your utility bill. No new account, no new autopay to set up.

There’s no minimum project size for ClearPath. If it’s an eligible measure, it can be financed.

What we’d tell you not to do

Don’t let financing talk you into a bigger scope than the house needs. The fact that you can finance $50,000 of work is not a reason to do $50,000 of work. If your attic needs air sealing and a top-off to R-60, that’s the job. We’ve turned down upsells we could have sold.

Don’t finance a job that was priced badly. A low bid that skips air sealing, skips the hatch dam, and leaves the baffles out isn’t cheaper — it’s less work. Spreading a bad scope over ten years doesn’t improve it. Ask any contractor to write out exactly what’s included before you compare numbers.

Don’t skip an available rebate just to move faster. The paperwork adds days, not weeks, and it comes off the top of what you finance.

The bottom line

Insulation is one of the few home improvements where the thing you’re buying starts paying you back the month it’s installed. Financing structures like ClearPath On-Bill exist precisely because that’s true — the program is designed around the assumption that the savings and the payment land close enough together to make the decision easy.

That doesn’t mean it’s automatic for every house, and we’re not going to pretend it is. But it does mean the upfront cost is a much smaller obstacle than it was two years ago.

If you’re in Boulder County and you’ve been putting off an insulation project because of what it costs, the honest answer is that there’s probably a way to do it now. Call us and we’ll tell you which one is yours — including if the answer is that you should wait.
