Boiler escape plan
Most UK homes will replace a boiler in a panic when it dies. This widget shows the carbon arithmetic of acting now versus locking in another decade of fossil heat, and turns into a personalised readiness plan with calendar reminders. It covers mains gas, heating oil and LPG – off-gas homes get their own numbers, and the strongest case for switching.
