Terms of Use
SaveWatt calculators are free planning tools. They provide estimates, not quotes, guarantees or professional advice.
Estimates only
Results depend on the numbers you enter and simplified formulas. Real bills, savings and payback periods can differ.
Check before deciding
Always confirm tariffs, technical suitability, installation quotes, incentives, warranties and safety requirements with qualified providers.
No advice relationship
Using SaveWatt does not create a financial, engineering, electrical, tax or legal advice relationship.
Accuracy
We try to keep the calculators clear and useful, but we cannot guarantee every result, assumption or page note is complete or current. Energy prices and product details can change quickly.
External links and advertising
The site may link to third-party websites or display adverts. We are not responsible for external websites, offers, claims or policies.
