WHY THIS EXISTS
Four quotes can look similar.
Four quotes can look similar.
The missing details are not.
System sizes, self-use assumptions, export rates and exclusions vary. A cheap headline can become an expensive choice when the evidence is incomplete.
Hidden scope gaps
Scaffolding, electrical upgrades, bird protection, monitoring and making good may sit outside the headline price.
Uneven protection
Product, workmanship and insurance-backed warranties are different things—and need separate evidence.

FROM QUOTES TO DECISION
A calmer way to choose.
- 1
Collect the complete proposals
Ask each installer for the system design, generation estimate, itemised scope, warranties and consumer protection.
- 2
Compare, then audit the detail
Normalise price and savings, then check roof design, battery backup, deposits, exclusions, warranties and contract terms.
- 3
Generate the missing-information email
Select a quote and the workbook creates a prioritised request list you can copy into an installer email.
- 4
Record and control the decision
Save a final summary, track quote revisions, payment milestones, handover documents and unresolved snags.
THIS PACK IS FOR YOU IF
You have—or expect—two or more quotes.
- You are considering rooftop solar, with or without a battery.
- You want to challenge assumptions without becoming an engineer.
- You care about scope and protection as well as payback.
- You want a reusable record of the decision.
IT IS NOT
A survey, design or installer recommendation.
- It does not predict your exact generation or savings.
- It does not replace technical, structural or electrical advice.
- It does not rank or refer installers.
- It is not for heat-pump-only quotes.

BEFORE YOU BUY
Straight answers.
What files do I receive?+
A 13-sheet Excel workbook, 15-page PDF guide, one-page 12-check reference, quick-start README and personal household licence in one ZIP file. The free check and four-page visual preview are also available before purchase.
Do I need Excel?+
The workbook is built and tested for Microsoft Excel. Other spreadsheet apps may open it, but layout, formulas or validation may vary.
Will it tell me which installer to choose?+
No. It makes the evidence and trade-offs easier to compare. You remain responsible for checking credentials, contracts, suitability and professional advice.
Does it calculate exact savings?+
No. It gives a consistent comparison using the assumptions you enter. Actual output and value depend on the home, design, weather, tariff and behaviour.
Can an installer or adviser use it with clients?+
The £19 pack is licensed to one household for personal use. Professional or client use requires a separate licence.
Are future updates included?+
Yes. Your purchase includes future version 1.x file updates delivered through the original store system. Separate future products and professional licences are not included.
Can I cancel or request a refund?+
Checkout asks you to request immediate digital delivery and acknowledge that the change-of-mind cancellation right ends when access begins. This does not affect your rights if the content is faulty or materially not as described. See the purchase terms before paying.
Who can buy the pack?+
The first release is sold to UK customers for one UK household’s own solar and battery project. A billing address is collected at checkout to confirm eligibility.
Is this an affiliate product?+
No. Hearthline created and sells the pack directly. Its contents do not rank or refer installers. Elsewhere, clearly labelled paid partner links may help fund the free planner; they never change the pack or a planning result.
