Step 1 of 8
What would you like help with?
We’ll build a plan that covers each one.
Choose one or more areas to continue
What is your housing situation?
This helps us avoid suggesting upgrades you cannot control. You can continue without choosing an answer.
What is your main heating system?
Your heating setup has a big effect on the kind of savings worth looking at. Choose the closest match, or continue if you are unsure.
Do you use gas at home?
This lets us tailor the plan to the fuel you use for heating, hot water and cooking.
Do you have a working smart meter?
Smart-meter data can reveal when you use energy and may open up more tariff options.
Do you have any of these now?
Choose everything that applies. These details can change where your best opportunities sit.
Which home upgrades are you interested in?
Select anything you may want to explore. Choose “None of these right now” if a larger change is not part of your plans.
Can you shift some electricity use?
For example, charging an EV or battery overnight, scheduling heating or hot water, or running appliances at lower-cost times.
