General
Questions to ask before signing a renewable energy contract
Use while you have the quote open. Get answers in writing where you can.

How to read your heat pump estimate before using the calculator
Layouts differ. Look for labels, not page numbers.
Read guide →The hidden costs of heat pump installation
The unit on the quote is rarely the whole retrofit bill.
Read guide →Why comparing a heat pump to an old boiler can distort the figures
If your boiler is old, almost any upgrade looks good. That does not show a heat pump beats a new gas boiler.
Read guide →What a proper heat pump quote should include
One total price is not enough. You need design assumptions you can question line by line.
Read guide →COP and SCOP explained in plain English
They tell you how much heat you get per unit of electricity, for stated conditions you should ask about.
Read guide →Why heat pump savings claims can be misleading
Headline savings are model outputs. The assumptions behind them are what you need in writing.
Read guide →Are air source heat pumps really cheaper than gas?
Sometimes yes on running costs. Often the answer depends on tariffs, SCOP and what boiler you compare against.

Read guide →How to check a solar and battery quote
Align scope before you compare price per panel.

Tariff-dependent savings are not wrong by default. You need the saving without that tariff too.
Read guide →Grants, loans and tariffs: know the difference
