Unleash Instant Insights with an Energy Savings Calculator
Air source heat pumps are booming in the UK. Yet, many homeowners hesitate. Why? Bills can skyrocket if you guess wrong. That’s where an energy savings calculator comes in. It takes guesswork out of upgrading. You plug in a few details. You see costs, grant breaks, carbon cuts—all in minutes. No fluff. Just clear numbers.
Finding the right tool can feel like wandering in a maze. RMI’s Green Upgrade Calculator is powerful, but it’s US-centric and built for broad tech stacks—from solar to EVs. If you just want a quick, UK-focused heat pump cost and grant breakdown, it can miss the mark. Our Megawave ROI & grant tool is different. It’s tailored for UK homes and businesses. And it factors in zero-carbon refrigerants like R290. Ready to find out what you’ll save? Estimate with our energy savings calculator
Why You Need an Energy Savings Calculator for Heat Pumps
Taming Traditional Heating Costs
Traditional boilers and furnaces guzzle gas. Bills creep up each winter. You swap a part, you pay more in repairs. You switch peaks and troughs. No clarity. An energy savings calculator gives you that clarity. Instead of rough guesstimates, you see your actual long-term costs. This simple step can cut your bill by hundreds of pounds each year.
How Heat Pumps Change the Game
An air source heat pump harvests warmth from outside. Even at low temperatures, it works. It can heat and cool your space. That dual role makes it versatile. Yet, installation and grant schemes vary by region. A generic calculator might ignore local grants or financing support. Our tool nails those details. It shows you:
- Installation costs after government grants
- Projected annual energy bills
- CO₂ reductions in tonnes
With every figure, you decide.
Comparing RMI’s Green Upgrade Calculator vs Megawave’s Tool
RMI’s Green Upgrade Calculator won fans in the US. It handles complex scenarios: geothermal options, hybrid configurations, detailed carbon data. It’s free and API-friendly. But:
- It’s optimised for US grants and incentives.
- It covers a wide range of upgrades, adding noise if you focus on air source heat pumps.
- It can overwhelm homeowners with 100+ input fields.
Megawave’s ROI & grant tool strips back the complexity. We focus on air source heat pumps. We highlight UK-specific grant schemes. And you get results in under five minutes. No unnecessary options. Just clear:
- Cost after grant
- Payback period
- Lifetime energy savings
By specialising, we deliver clarity. And that means faster decisions.
How Our Air Source Heat Pump ROI & Grant Tool Works
Our interactive energy savings calculator breaks down into three steps:
-
Input Your Details
– Postcode (we fetch local grant rates)
– Property type (detached, semi, flat)
– Current heating fuel and usage -
Review Grant and ROI Estimates
– Automatic grant lookup (ECO4, Boiler Upgrade Scheme)
– Graphical ROI timeline
– Net installation cost -
Explore Lifetime Savings
– Annual energy consumption forecast
– CO₂ emissions reduction
– Comparison to gas or electric alternatives
It’s that simple. No extra fields you don’t need.
- Input accuracy rivals advanced calculators.
- Local incentives appear instantly.
- Results update live as you tweak assumptions.
After a quick run, you have a realistic projection—not a ballpark guess. And you can refine settings like refrigerant type (R290 vs R32), piping length or hybrid switching points. That kind of depth, with a clear interface, makes decision-making easy.
Grants and Incentives Made Simple
UK grants can be tricky. Some schemes cap payments by region. Others require income thresholds. Our energy savings calculator crawls official data sources. You get:
- ECO4 rebates matched to your local authority
- Boiler Upgrade Scheme amounts
- Additional local council grants
No more hunting through government PDFs. Everything appears in one summary. Then you see your net cost at a glance. That clarity means you know exactly how much you’ll pay—and save.

- Refrigerant leakage assumptions
All to fine-tune carbon and cost projections. Want to lock in a precise quote? Secure your heat pumps installation quotation
Pairing With Solar and Financing Options
Solar Integration
Pairing air source heat pumps with rooftop solar is a no-brainer. But you need to size your panels to match post-upgrade usage. Our energy savings calculator shows annual kWh demand. You can then:
- Select PV array size (e.g. 8 kW)
- Forecast self-consumption rates
- Estimate feed-in tariffs
This helps you design a system that offsets most of your pump’s electricity draw. Pairing both cuts bills further—and shrinks your carbon footprint.
Finance and Support
Megawave knows that up-front costs still worry homeowners. That’s why we offer:
- Flexible 0% APR finance plans
- Pay-as-you-save options (no initial deposit)
- Expert maintenance packages
And our tool factors finance repayments into your monthly outgoings. So you see net savings after loan costs. Clear numbers help you choose the best deal.
