The ritual page

What the file tells you

Every installer's quote comes with its own savings estimate and its own maths. This sheet runs all of them the same way at your energy prices — payback, lifetime return, what it does to cash flow if financed — and tells you which upgrade to do first and which to skip.

01 · verdictPayback — years to recover the cost vs your limit and its lifetime

02 · verdictLifetime — net saving over its life with energy inflation, return on cost

03 · verdictCash — up front after grants, financed per month, net per month

Sheets in the workbook

✓Analyzer · pick an upgrade: payback, three verdicts, three checks

✓Upgrades · one line per upgrade with the quote and the savings

✓Settings · your energy prices, inflation, longest payback you accept, cash available

How it works

1Set your energy prices — electricity, gas, fuel, inflation, your payback limit, cash available

2Add each upgrade as one line — cost, grant, kWh and litres saved, maintenance, lifetime, financing

3Pick an upgrade on Analyzer — payback in years, DO IT / MAYBE / SKIP, the order to do them in

Who it is for

Homeowners with three quotes on the table and a feeling that the salespeople's numbers do not add up.
