Real tech solutions. Real savings.
Tweak and Save is all about using tech to spend less and save more. It’s a collection of videos and articles sharing tech tips and fixes that save you money at home. Where we can measure it, we show what each tweak actually saved us, in pounds.
What you’ll find here
Smarter energy
Solar, a car that powers the house overnight, a heat pump and tariffs that do the heavy lifting. What it cost, and what it saved.
Home automation
Home Assistant setups that run quietly in the background and cut the bills without anyone touching a switch.
Money tools
Trackers, planners and the odd tool I’ve built myself. What they showed me, and what I changed because of it.

The house behind the channel
I’ve spent years tinkering with the tech in my own home: solar panels, an EV that runs the house at night, a heat pump, and more automations than is probably sensible.
Tweak and Save is where I share what works, what doesn’t, and what it all saves. No hype, no shouting. Just real numbers from a real house.
