A few common questions

Is this a fixed price?

This is an estimate based on the details you’ve shared. Before anything goes ahead, we’ll review your roof and system design together and confirm final pricing.

Do I have to decide now?

No. Nothing on this page commits you to anything. Most customers use this estimate as a starting point and take time to explore their options.

What happens if I book a call?

We’ll talk through your estimate, answer your questions, and sense-check the numbers. There’s no obligation to go ahead.

Can the system price change?

It can, and that’s normal. If anything changes, we’ll always explain why and agree everything with you before confirming a final design.

What if solar isn't right for my home?

We’ll tell you. If solar isn’t a good fit, we’ll be upfront and help you understand why.
