Utility Upgrade

Three draughty rental houses with high bills, and a budget for each. Draught strips, LED lights, insulation, a new boiler, solar panels, a heat pump: pick the mix that saves the most over ten years for the money.

Payback

How to play

Pick. Each upgrade shows its cost and yearly saving. Payback = cost ÷ yearly saving.
Install. Ten years of bills later, your savings minus the costs are compared with the best mix for the budget.
Three levels. Beginner, Intermediate or Expert, picked before you play: the content and the clock change, and each level keeps its own best score.
Coins. Example numbers in plain fictional coins, made up for the game. Not financial advice.

Quick tips

Payback first. Cost ÷ yearly saving = years to pay back. Shorter is better.
Small wins add up. Cheap fixes often pay back in a year or two.
