Every energy site is quietly selling something. The heat-pump company recommends a heat pump. The solar company recommends solar. We're neither — we show you your honest best options, and the working behind every number.
Around a dozen questions. No sign-up to see your results. Every answer changes the numbers — and you can see exactly how.
A complete, independent PDF: your route in order, every cost and grant, the quote red-flags to watch for, the exact questions to ask installers, and the assumptions behind every number. The thing to read before you spend tens of thousands.
One-off — no subscription. Independent: the report can't be bought by installers, only by you.
It's one of the biggest, least-reversible decisions a household makes — and almost everyone you can ask has something to sell. So people guess, copy a neighbour, or trust whoever quoted last. That's how expensive mistakes get made.
An installer's job is to sell their kit. A grant site lists whatever grant exists. None of them are paid to tell you that doing nothing might be your smartest move this year.
"Heat pumps are cheaper to run" — until they aren't, in a leaky house. Real running costs depend on your walls, your fuel price and your habits. Nobody shows the working.
What you can claim flips completely depending on which side of a border you live on. The same house can be worth €12,500 in grants in the South and almost nothing in the North.
The single biggest mistake is doing the right things in the wrong order — fitting a heat pump before insulating. We put sequencing first, because that's where the money is lost.
After building my own house, I realised nobody would give a straight answer about heating — every answer came with a sales pitch attached. So I built the tool I wish I'd had: independent, plain-spoken, and on your side of the table.
— Why I built thisGrant support for the exact same upgrade changes dramatically depending on where you live. My Energy Engine always uses the rules for your jurisdiction — and tells you plainly when you're getting the short end.
Heat-pump grant (system + central heating + €4,000 renewable-heat bonus for ditching fossil fuel). Plus attic ~€2,000, cavity ~€1,800, solar €1,800. The most generous package these islands have ever seen.
Home Energy Scotland — not the Boiler Upgrade Scheme. A £7,500 heat-pump grant (£9,000 rural/island), not means-tested, plus an interest-free loan for the rest and insulation funded up to 75%. Quietly the best deal in Great Britain.
Boiler Upgrade Scheme for an air- or ground-source heat pump — rising to £9,000 for off-gas oil/LPG homes from July 2026. Biomass £5,000 in rural off-gas homes. Insulation via means-tested ECO4.
No Boiler Upgrade Scheme, no SEAI. NISEP help exists but is income-assessed (roughly under £28k single / £35k household), so many owner-occupiers qualify for little beyond 0% VAT. The honest gap we'll never hide from you.
Trust is easy to claim and hard to prove. Here's exactly how My Energy Engine stays on your side.
The ranking is a fixed model of physics and economics. No installer, supplier or advertiser can move their result up. The maths runs the same for everyone.
Every option opens up to reveal the assumptions — your fuel price, heat demand, efficiency, grant. If you disagree with an input, you can see it and change it.
Nobody can predict your bill to the euro. We give honest ranges and tell you what would tighten them — like adding your real BER.
Sometimes keeping your boiler one more year is the right call. A tool that can never recommend that isn't advising you — it's selling to you.
A one-page, jargon-free report you can hand to any installer to get honest quotes — with your options, costs, grants and the questions to ask. We'll send it over and let you know when auto-fill from your Eircode/postcode goes live.
No spam, no reselling your details. One email with your report, the odd genuinely useful update.
