The best OCPP-compatible home chargers in the UK for 2026 are the Zaptec Go 2 (best overall), the Rolec EVO (best British-built), and the NexBlue Point 2 (best value). All three expose a genuine OCPP 1.6J endpoint rather than relying on proprietary-only smart charging, which means you can connect them to any compatible tariff management system and switch supplier without changing hardware.
If you want the background on why OCPP matters and how to check that a charger truly supports it, read our full OCPP EV charging guide before shortlisting.
What “OCPP-Compatible” Actually Means for UK Buyers
The phrase “smart charging” on a product listing tells you almost nothing useful. Many chargers use proprietary cloud connections that lock you to one supplier’s app. Genuine OCPP compatibility means the following:
- An explicit OCPP version on the spec sheet. Look for “OCPP 1.6J” or “OCPP 2.0.1”, not just “smart” or “app-controlled”.
- An open or requestable endpoint. Some manufacturers expose the OCPP connection as standard; others require the installer to request credentials via a portal.
- UK smart-charging compliance. The charger must meet the Electric Vehicles (Smart Charge Points) Regulations 2021, which came into force on 30 June 2022.
- Tariff compatibility confirmed. If you plan to use Intelligent Octopus Go, E.ON Next Drive, or OVO Charge Anytime, check the specific compatibility list — OCPP alone is not always sufficient if the tariff uses a direct API integration instead.

Prices verified at time of writing; figures vary — verify current data before purchasing.
1. Zaptec Go 2 — Best Overall
The Zaptec Go 2 is our top pick for OCPP compatibility because it exposes a native OCPP 1.6J endpoint via the Zaptec portal, supports three-phase power at up to 22 kW where the supply allows, and ships with PEN fault protection built in — a safety requirement that some cheaper units still lack.
The Go 2’s hardware is built on a platform designed for both residential and commercial use, which means the OCPP implementation is mature and well-tested in the field. The charger itself is untethered, connects via Type 2 socket, and carries Zaptec’s characteristic Scandinavian design.
Pros
- Native OCPP 1.6J, well-documented API
- Three-phase ready (22 kW when supply permits)
- PEN fault protection built in
- Compact, high-quality build
Cons
- OCPP endpoint requires registration via Zaptec portal
- Untethered only — you carry your own cable
- Higher RRP than budget alternatives
2. Rolec EVO — Best British-Built
Rolec is one of the few remaining UK-based EV charger manufacturers, building its products in Boston, Lincolnshire. The EVO is the company’s flagship home unit, widely specified by NICEIC and OZEV-registered installers across the UK.
OCPP 1.6J is available on the EVO on request — the installer needs to obtain the endpoint from Rolec’s commercial portal. For residential customers, this means confirming the process with your installer before purchase, but it is a straightforward activation once arranged.
The EVO is available in both tethered and untethered configurations and carries a wide installer base, which makes after-sales support more accessible than with some imported brands.
Pros
- UK-manufactured, strong installer network
- Tethered and untethered options
- OCPP 1.6J available
- Competitive pricing
Cons
- OCPP requires installer activation (not open by default)
- No native solar diversion mode
- Fewer premium app features than rivals
3. NexBlue Point 2 — Best Value OCPP
The NexBlue Point 2 is the most affordable charger on this list that ships with OCPP 1.6J as standard. It is compatible with Intelligent Octopus Go and carries the smart-charging regulation compliance required for UK sale. For drivers who want genuine OCPP interoperability without spending close to £800, this is the one to consider.
The build quality is functional rather than design-led, and the app is simpler than Ohme or Hypervolt’s offerings, but for pure OCPP interoperability it delivers everything most home users need.
Pros
- OCPP 1.6J standard, no gating
- Intelligent Octopus Go compatible
- Lowest RRP on this list
- Tethered and untethered options
Cons
- Less polished app experience
- Basic aesthetics compared to premium rivals
- Limited solar integration
4. Ohme Home Pro — Best for Smart Tariffs
The Ohme Home Pro takes a different approach to smart charging: rather than relying primarily on OCPP, it integrates directly with Octopus Energy’s Kraken platform, giving Intelligent Octopus Go customers a seamless automatic scheduling experience. It also exposes an OCPP endpoint for other use cases.
The practical result is that IOG customers get the most tightly integrated charging experience available — the charger adjusts dynamically as Octopus shifts the off-peak window, without any manual input. The built-in display and cable management slot are features absent from most rivals at this price.
Pros
- Native Intelligent Octopus Go integration (best-in-class)
- Built-in display showing tariff and charging status
- Also supports OCPP 1.6J
- Cable management integrated
Cons
- Tethered only (7.4 kW cable fixed)
- Less useful if you are not on Octopus
- No solar diversion mode
5. MyEnergi Zappi — Best for Solar
The MyEnergi Zappi combines OCPP 1.6J with native solar diversion via CT clamp, making it the only charger on this list that can automatically shift surplus PV generation into your EV without a separate energy management system. Eco mode diverts available solar generation; Eco+ maximises self-consumption by drawing only from surplus PV, pausing when none is available.
Zappi is also officially supported by Intelligent Octopus Go via native integration, and it connects into the MyEnergi ecosystem (Libbi battery, Eddi immersion diverter) for households building a broader home energy setup.
Pros
- Best-in-class solar diversion (Eco / Eco+ modes)
- OCPP 1.6J with Intelligent Octopus Go native support
- MyEnergi ecosystem integration
- Tethered with good cable management
Cons
- Higher RRP for the functionality
- Bulkier than slim-profile rivals
- App can feel complex for non-technical users
6. Hypervolt Home 3 — Best App and Smart Home
Hypervolt’s Home 3 is the most app-focused charger on this list. The companion app carries live tariff data, charging history, and smart scheduling, and the charger integrates with Amazon Alexa and Google Home for voice control. The LED ring indicator is one of the more attractive design elements in the market.
OCPP is available on request, which limits its use in third-party management platforms without installer involvement. For home users who plan to stay within the Hypervolt ecosystem, the native integration covers everything most drivers need.
Pros
- Excellent app and smart home integration
- Alexa and Google Home compatible
- LED status ring and polished industrial design
- Intelligent Octopus Go compatible
Cons
- OCPP on request only (not open by default)
- No native solar diversion
- Premium pricing for what is essentially an app-led experience
How We Chose These Chargers
Every charger on this list was assessed against four criteria:
- OCPP version confirmed on the spec sheet. We checked manufacturer documentation, not marketing copy.
- UK smart-charging regulation compliance. All units shipped after 30 June 2022 must meet the Electric Vehicles (Smart Charge Points) Regulations 2021.
- Real-world tariff compatibility. We cross-referenced each model against the Octopus Intelligent Go compatibility list and major UK tariff provider documentation.
- Installer availability. UK OZEV-registered installers must be available for each model.
OCPP Compatibility Checklist Before You Buy
Before committing to a charger, work through these questions:
- Is OCPP enabled out of the box, or does it require activation? Ask your installer specifically. “Smart charging” does not always mean OCPP is on by default.
- Which OCPP version does it support? OCPP 1.6J is the minimum; 2.0.1 is preferable for future-proofing.
- Is there a cost for OCPP access? Some brands charge for commercial OCPP accounts. Confirm for residential use.
- Is your chosen tariff compatible? Check the Octopus Intelligent Go list if you are on or planning to switch to IOG; check E.ON Next Drive and OVO Charge Anytime compatibility separately.
- Will OCPP work with your solar or battery setup? If you have solar panels or a home battery, confirm the charger’s CT clamp or management system integration before purchase.

Frequently Asked Questions
Are all UK home chargers OCPP-compatible? No. Many home chargers use proprietary cloud connections that lock you to one supplier’s app and back-end. To verify genuine OCPP compatibility, look for an explicit version number (OCPP 1.6J or 2.0.1) on the manufacturer’s spec sheet, and confirm with your installer that the endpoint is active or can be activated for residential use.
What is the best OCPP charger for Intelligent Octopus Go? Ohme Home Pro and MyEnergi Zappi both offer native Kraken API integration with Intelligent Octopus Go, giving the most seamless automatic scheduling. If you prefer a non-native integration, NexBlue Point 2 and Zaptec Go 2 both work via OCPP-based management platforms compatible with IOG.
Does OCPP work with solar panels? OCPP itself is generation-neutral. Solar diversion on the Zappi uses CT clamp logic running locally in the device, separate from the OCPP connection. For solar-integrated charging on other models, a CT clamp or home energy management system is required alongside the charger’s OCPP connection.
Is OCPP 1.6 still good enough in 2026? Yes. OCPP 1.6J remains the standard for UK home smart charging compliance and supports all current UK tariff integrations. OCPP 2.0.1 adds future-proofing (V2G messaging, mandatory TLS, ISO 15118 support), but for day-to-day home charging in 2026, 1.6J is fully sufficient.
Will my OCPP charger still work if I switch energy supplier? Yes — interoperability is exactly the point of OCPP. Provided your new supplier’s management platform supports OCPP (as all major UK smart tariff providers do), your charger connects without hardware changes. In some cases you may need to update the charger’s CSMS endpoint via the app or installer portal.
