Step 1 of 10
Your energy use
These figures help us avoid generic savings estimates.
Preview only
This is the published layout of Stage 1. The assessment journey is not built in this stage, so nothing you type is collected, checked or sent.
We use this for regional sunlight and energy costs. Do not enter your full postcode.
Usually shown on your latest electricity bill.
Low: home often empty. About half: mixed routine. Most of it: home most days.
Document files stay in this browser. Confirmed form values are sent transiently for assessment and are not saved to QuoteGuardian storage.
Why context matters
Two identical systems can deliver very different results.
- Regional solar conditions
- Your actual electricity use
- When you use electricity
- Roof direction and shading
- Technology already installed
We ask only for what is needed to assess a quotation. Your full address is not required.
