Jay Clarke is an independent NatHERS assessor and upgrade coordinator.
No products to sell. No installer kickbacks.
Just impartial advice...and someone to actually make it happen.
Be Honest.
You've been meaning to do this for, what - two years?
You're not lazy. You're not cheap. The system is just genuinely confusing. Here's the proof.
01
You have three quotes and zero decisions.
Each tradie told you something different. One wants to replace everything. One says start small. You're not sure who to trust, because they all want to sell you something.
02
You've read the articles. Done the research. Still stuck.
Solar first? Insulation? Heat pump? It depends, apparently. On a hundred things. You need someone to just tell you clearly and transparently what to do next.
03
You're selling and quietly dreading the energy question.
Buyers are asking. Agents are guessing. You want the actual number - your NatHERS star rating - before it becomes their leverage.
Sound like you? Good. That's exactly what Jay does.
How it works.
Simple. Four steps. Done.
01
Chat for 15 minutes. For free.
Tell Jay what you're working with and what's holding you back. If HomeUp isn't the right fit, he will say so.
02
Jay assesses your home.
A full NatHERS thermal performance assessment. Get a science-based explainer of how your home performs and why it costs you what it does.
03
You get a roadmap. Not a wish list.
What to do first. What to do eventually. What's not worth doing. With realistic cost estimates, not best-case scenarios.
04
Jay coordinates it. Or doesn't. Your call.
Hand you the plan and step back. Or manage the whole thing; trades, rebates, installs, post-install check. You decide how much you want off your plate.
Services.
Pick your starting point.
A plan. The whole project. Or just the certificate. Whatever you need, there's a service that fits.

The Honesty Bit.
Jay doesn't sell heat pumps.
Most people giving you upgrade advice have something to sell.
An installer pitches their products. A retailer has a promo running. A utility company has a "retail partnership".
Jay gets paid by you. That's it.
No referral fees. No supplier deals. No preferred tradies who owe him a favour.
❌ Doesn't sell heat pumps, solar, or insulation
❌ No commissions, kickbacks, or referral fees
❌ No affiliation with any rebate delivery partner
✅ Accredited NatHERS assessor. Paid by you, accountable to you
✅ The recommendation is always what's right for your home. Not what's on special.
1/3
Of global CO₂ comes from buildings. Half from homes. Your upgrade actually matters beyond your bill.
4.5★
Average star rating jump achievable in pre-1990s Melbourne homes. With the right upgrades, in the right order.
6 weeks
From first call to completed upgrade, including rebate claims, for a typical whole-home project.
Real homes. Real numbers.
Melbourne homeowners who stopped researching and started doing.
TWO YRS OF INDECISION · NORTHCOTE
$400/qtr saved.
Three conflicting quotes, two years, zero action. One assessment and a clear roadmap later: insulation, heat pumps, draught sealing. Done in six weeks.
"We needed someone to tell us what, the order, and why. Jay did that."
PRE-SALE HUSTLE · RINGWOOD
1.5★ → 6.3★
1970s home, heading to market. Three targeted upgrades; ceiling insulation, draught sealing and solar PV. Shifted the rating by almost five stars. Sold $22k above reserve.
"Buyers literally mentioned the rating in their offers."
COMFORT FIRST · PASCOE VALE
Kids sleep through winter.
Draughty weatherboard. Two small kids. The brief wasn't "save on bills", it was "make this house liveable in July." Done...but with lower running costs as an added bonus.
"We stopped thinking about bills and prioritised thinking about comfort."

❌ Not an installer. Not a supplier.
❌ No referral fees. No preferred tradies.

Most assessors deliver a report and disappear.
Jay doesn't. He stays in the problem until it's actually solved, which means understanding not just what your home needs, but what's stopping you from doing it.
That's where his change management background comes in. Jay has worked with homeowners across Melbourne and regional Victoria who had all the information and still couldn't pull the trigger. Conflicting advice. Household disagreements. Life getting in the way. He's seen it all, and he knows how to get things unstuck.
He's not going to tell you what you want to hear. He's going to tell you what's worth doing, what isn't, and in what order. Then help you do it.
