Home Energy System Optimisation
You’ve got the solar, the battery, the heat pump, or the EV charger.
We make them actually work together.
Most installers fit their one box, leave it on factory settings, and never look at how it affects the rest of your home. If your bills are still too high, your battery runs out too early, or you’re tired of juggling different apps that don’t make sense—we fix it.
You don’t need to know why it isn’t working.
You just want it sorted.
Most homeowners we speak to have spent thousands on great equipment, only to feel let down by the results. Usually, nothing is broken—the parts just haven’t been set up to work as one system.
Battery & Smart Tariffs
Your battery should charge up overnight on cheap rates and carry your house through the expensive evening peak. We sort out the settings so you stop paying peak grid prices while your battery sits empty or idle.
EV Car Charging
A common headache is plugging your car in and watching it drain your entire house battery in an hour. We set up your car charging and home battery so the car charges from cheap grid slots or spare solar—never stealing your home’s stored power.
Heat Pump Integration
Heat pumps cost a fortune if they are left running like an old gas boiler during expensive peak hours. We tune your heating and hot water timings so they work gently alongside your battery and smart tariff.
Stopping Systems Fighting
When solar, batteries, heating, and car chargers are fitted by different companies, they often work against each other. We join everything up so the house looks after itself quietly in the background—with no Home Assistant or DIY tinkering required.

Data addict, or just want it to work—
Joined Up Energy has you covered.
You can completely ignore your system and let it quietly save you money in the background, or enjoy one crystal-clear live dashboard instead of juggling four confusing manufacturer apps. Below is the actual live data streaming right now from our own home in Oxfordshire.
Live Battery Charge Cycle & Home Demand
Real-World Proof • Oxfordshire
Case Study: How Our Own Family Home Runs
Our home in Oxfordshire has solar panels, home batteries, an air source heat pump, and electric cars. When each piece was just running on its own standard settings, they constantly worked against each other. Here is what changed once we joined them up.
Everything Guided by One Quiet Local Brain
Instead of four separate apps fighting each other, one controller coordinates where every kilowatt goes.
Eliminating Expensive Peak-Rate Power
By teaching the battery, heat pump, and car charger to coordinate around cheap overnight slots and sunshine, expensive daytime grid import dropped to almost zero.
Battery Level vs. Expensive Grid Hours
Instead of running flat by dinner time, the battery tops up overnight on cheap rates, catches daytime solar, and carries the whole house through the evening peak.
Heating the House for ~2p per kWh
Because our heat pump produces nearly 4 units of heat for every 1 unit of electricity—and runs off battery power bought at 7p overnight or free solar—our actual cost of heat is under 2p per kWh (less than a third of the cost of a mains gas boiler).
Four Integrations That Made the Biggest Difference (And Why)
Weather-Aware Overnight Charging
Why it works: Instead of blindly filling the battery to 100% from the grid every night, our system checks tomorrow’s sunshine forecast. If a sunny morning is coming, it only half-fills the battery overnight so there is plenty of empty room to capture free solar energy.
Protecting the House Battery from the Cars
Why it works: Previously, plugging a car in on the driveway tricked the house battery into emptying itself into the car. Now, the battery and car charger coordinate: daytime plug-ins wait for cheap tariff slots or genuine spare solar, keeping the house battery safe for the evening.
Heating Hot Water & Floors at Cheap Times
Why it works: Water cylinders and floors hold heat for hours—just like a battery. By heating the hot water tank overnight on 7p electricity and nudging the heating up when solar is strong, the heat pump barely has to work during expensive evening hours.
Automatic Holiday & Away Mode
Why it works: Standard systems keep buying grid power to charge the battery every night even when the house is empty. When we go away, the house drops into a quiet standby that runs purely off daytime sunshine and warms the house back up before we get home.

Not an installer. A system optimiser.
Joined Up Energy is run personally by Ryan Williams, as part of Electrical Warehouse Limited.
After spending years optimising my own home’s solar panels, batteries, heat pump, and electric cars to work together automatically on smart tariffs, I realised how many homeowners were stuck with expensive systems that nobody had ever properly joined up.
Installers want to sell you more panels or a bigger battery. I don’t sell boxes—my only job is to walk in, understand what you already have, and make the whole system work properly for you.

Smarter handovers. Zero unpaid app callbacks.
Great installers want to complete a tidy, compliant job and move onto the next project—not spend evenings troubleshooting Octopus tariffs or why an EV charger is draining a customer’s battery. Partner with us for pre-job kit specification, fixed-fee smart commissioning, and to offer our live whole-home dashboard on your installs.
