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.

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.

Annual Electricity Mix

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.

Before (Separate Systems) Avg. ~21p / kWh
45% Peak
30% Cheap
25% Solar
After (Joined-Up System) Avg. ~4.2p / kWh
52% Cheap Off-Peak
45% Free Solar
Expensive Peak Grid (~30p) Cheap Off-Peak (~7p) Free Solar (0p)
A Typical 24-Hour Day

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.

Evening Peak (0W Grid Used) 7p Cheap Window 100% 50% 0% Solar tops battery to 95% Before: Car drained battery by 4pm 00:00 06:00 12:00 18:00 24:00

Four Integrations That Made the Biggest Difference (And Why)

01

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.

02

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.

03

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.

04

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.

Ask About a Tune-Up

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.

Tell us what’s going on with your system

Drop us a message using the form, or email directly. Don’t worry about technical details—just tell us roughly what you have (solar, battery, heat pump, or EV charger) and what isn’t working the way you hoped.
