INDEPENDENCE BOUNDARY
Payment buys project control—not a favourable recommendation.
Project Pass does not rank installers, provide a technical survey or guarantee savings. Affiliate relationships never alter calculations or comparison scores, and information is not shared with a partner unless you make a separate, explicit request.
BEFORE JOINING
Questions about founding access.
Why twelve months instead of a monthly subscription?+
Most home-energy upgrades are projects rather than permanent software needs. A non-renewing project pass is easier to understand while we validate which reminders and long-term records create genuine recurring value.
I already bought the £19 Quote Pack. Do I pay again?+
No during the founding release. A Quote Pack purchase linked to the same account unlocks the first Project Pass workspace. Before permanent pricing, existing buyers will receive either continued access or a clear £19 credit.
Does Hearthline check the engineering design?+
No. Hearthline checks whether important information has been supplied and helps compare written assumptions. Technical suitability and design must be confirmed by appropriately qualified professionals.
Will an installer receive my quotes or personal details?+
No. Your workspace is private. A future introduction feature will name the exact recipient and ask for separate permission before sharing selected information.
