What Agile integration actually means for a charger
Not all smart chargers are equally smart. There are three distinct levels of Agile compatibility, and the difference between them is worth up to £100 per year in real savings.
Level 1: The dumb charger with a manual timer. You plug in, open the car app (or the charger app), and set a start time manually. You get cheap overnight rates if you remember to check prices and adjust your schedule. This works, but it requires daily input and still misses the cheapest windows most nights. Any 7kW charger fits this category.
Level 2: The smart charger with a fixed schedule app. The charger has its own scheduling capability. You set a window (say, 12am to 6am), and it charges within that window. This is better. You capture most cheap overnight rates without daily checking. Still, it doesn't respond to live Agile prices. It charges at 12am whether electricity is 2p or 18p that half-hour.
Level 3: The intelligent charger that reads live Agile price data. This is where Agile integration becomes transformational. These chargers connect directly to Octopus's API, read live half-hourly prices, and schedule charging into the cheapest specific slots before your departure time. If prices spike at 2am but crash to 1.5p at 3:30am, the charger waits. If a plunge pricing event drops prices to -14p at 1am, the charger starts immediately.
The gap between Level 2 and Level 3 is approximately £50-100 per year in extra savings on top of what a fixed schedule delivers. Over a five-year charger lifespan, that's £250-500 in additional benefit, enough to justify paying more upfront for the right hardware.
OHME: the charger built for Octopus Agile
OHME is the most tightly integrated Agile charger available in the UK. Its core feature is native Octopus Energy account linking: you connect OHME directly to your Octopus account, and it reads live Agile prices in real time without any manual configuration.
Once set up, OHME works like this. You plug your car in when you get home and tell it what time you need to leave and how full you want the battery. OHME then looks at every half-hour price slot between now and your departure, identifies the cheapest windows that add up to enough charge time, and schedules exclusively into those slots. You do nothing else.
OHME also responds automatically to plunge pricing. When Agile prices go negative, OHME detects this in real time and begins charging immediately, even if it wasn't scheduled. If your car is already at your target level, OHME may charge beyond it during plunge events to capture the credit. This behaviour alone can add £30-50 per month in bill credits during high-wind winter months.
OHME Home Pro is the flagship model for new home installations. Installed cost is approximately £800-1,000 depending on your property and the electrician. The app is clean and reliable. For drivers who want pure Agile optimisation with no daily effort, OHME is the clear recommendation.
Best for: Drivers who want fully automatic Agile price optimisation. Pure Agile users without solar panels.
Zappi: the best charger for solar and Agile households
The Zappi charger from myenergi was built for homes that generate their own solar electricity. It manages two energy sources simultaneously: the solar panels on your roof and the grid. Its Agile integration layer allows it to manage all three sources together.
Zappi runs in three modes. Fast mode draws maximum power from the grid immediately, ignoring both solar generation and price. Use this when you genuinely need the car charged quickly. Eco mode prioritises solar self-consumption first. When your panels generate more electricity than the house is using, that surplus goes into the car. When solar drops below what's needed, Zappi tops up from the grid. Eco+ mode is solar-only. Zappi waits until solar generation is sufficient before drawing any grid power at all. The car charges slowly but entirely from your own roof.
The Agile integration in Zappi works through the myenergi app. You connect your Octopus API credentials, set a departure time and minimum charge level, and the app builds an overnight schedule using live Agile price data. During the day, Zappi uses solar. Overnight, it fills remaining capacity from the cheapest Agile slots.
For households with a typical 4kW solar installation and an EV driven 12,000 miles per year, the combination of Zappi and Agile can reduce annual EV charging cost to under £100. Solar handles 40-60% of charging in summer. Cheap Agile rates handle the rest year-round.
Installed cost for a Zappi is approximately £1,000-1,200. The premium over basic chargers is justified for solar households. For homes without solar, OHME is a better choice at lower cost.
Best for: Homes with solar panels. Maximum Agile and solar combination savings.
Indra Smart PRO: comprehensive scheduling from a UK manufacturer
The Indra Smart PRO is made in the UK by the Indra Renewable Technologies team. It positions itself as a premium smart charger with full scheduling, energy management, and Octopus Agile compatibility built in.
Indra connects to Octopus's API and supports Agile price-response scheduling through its companion app. The hardware is solid: it uses a Type 2 connector, delivers up to 7.4kW, and has a reputation among installers for build quality and reliability in British weather.
The app gives you detailed scheduling control, live price visibility, and charging history. Agile price response is available through the Octopus integration. Indra's energy management features are comprehensive, making it a good fit for households that want detailed oversight of their home energy use alongside their EV charging.
Installed cost is approximately £900. Not as deep in Agile-native features as OHME, but a well-rounded choice for drivers who want comprehensive scheduling options and prefer British-made hardware.
Best for: Drivers who want comprehensive scheduling control and detailed energy management. Those who prefer UK-manufactured hardware.
Pod Point: the simple choice for reliable overnight charging
Pod Point is one of the most widely installed home EV chargers in the UK. It is reliable, well-supported, and backed by EDF Energy's infrastructure network. What it doesn't offer is deep Agile price integration.
Pod Point's app allows you to set scheduled charging windows. If you set it to charge between 1am and 5am every night, you'll capture low overnight Agile rates reliably. You won't capture specific cheap half-hour slots, and the charger won't respond to live price data or plunge events. But it will charge your car cheaply and predictably every single night with no ongoing intervention.
For drivers who don't want to think about energy pricing and simply want a 7kW charger that works, Pod Point delivers. The installed cost is approximately £700-900, making it the most affordable option on this list.
If you add the habit of checking AgileAlert's live price dashboard each evening and adjusting your start time manually, Pod Point can capture most of the Agile savings at a lower hardware cost than OHME or Zappi.
Best for: Drivers who want simplicity and reliability over maximum Agile optimisation. Budget-conscious buyers comfortable with a manual check each evening.
Which charger to choose: the decision guide
The right charger depends on your household setup and how much automation you want. Here is the direct answer for each scenario.
I have solar panels. Choose Zappi. It is the only charger that manages solar and Agile together intelligently. Nothing else does this combination as well.
I want fully automatic Agile price optimisation. Choose OHME. It has the deepest native Octopus Agile integration of any charger, responds to plunge pricing automatically, and requires no daily checking once configured.
I want comprehensive scheduling and energy management. Choose Indra Smart PRO. It gives you detailed control with good UK-made build quality and solid Octopus Agile compatibility.
I want simplicity, reliability, and a lower upfront cost. Choose Pod Point. Set a 1am-5am charge window and you'll capture most cheap overnight rates. Check AgileAlert when you want to optimise further.
If you drive high mileage (15,000+ miles per year), the annual saving difference between OHME (Level 3 integration) and Pod Point (Level 2) can reach £100 per year. Over five years, that gap pays for the OHME premium. For low-mileage drivers, the simpler options make more financial sense.
Installation costs and OZEV grant eligibility
Home EV charger installation in the UK typically costs £800-1,200 all-in, including the charger unit, labour, and any minor electrical work required. The exact cost depends on your property, how far the charge point needs to be from your consumer unit, and whether any additional cabling or earthing is needed.
The government's OZEV (Office for Zero Emission Vehicles) EV charger grant provides £350 towards the cost of installing a home charge point. As of 2026, the grant is available to renters (both homeowner tenants and private renters) and to flat-dwellers in buildings where the landlord consents to installation. It is no longer available to homeowners of houses who are the owner-occupier. Commercial properties and residential car parks still qualify under separate schemes.
To claim the OZEV grant, you must use a government-approved installer from the OZEV approved installer list. All the major charger brands (OHME, Zappi, Indra, Pod Point) work with OZEV-approved installers. The grant is applied at the point of installation, so you pay the reduced amount from the start rather than claiming it back.
Renters face one additional step: written consent from the landlord is required. Most landlords accept this when presented with a clear explanation, since the installation adds value to the property and the tenant pays for it.
Even without the grant, the payback period on a smart home charger is typically two to three years for average-mileage EV drivers on Agile, and under two years for high-mileage drivers who capture plunge pricing.
