Ev charger

Engineer came on time was very polite did the job very neatly. Explained everything and helped install the new app on the phone. Very pleased with how it turned out. Thank you very much. 👏🏾👏🏾👏🏾

Response from developer

We're very glad it all went smoothly, and hope you continue to have a good experience with your Sync Energy charger!

Masterplug EV charger

Was made to move to this app from the Monta app that was previously used on the Masterplug EV Charger. This app does not allow you to input the kwh rate, and does not calculate session cost, or enable monthly report to be produced showing the charging costs - All basic functions on other charging apps. I’m now unable to calculate monthly charge costs for business expenses on this app. Really poor.

Edit based on developer response - So I don’t want, and am not able to use tariff sense as you don’t list my tariff, and I am capable of setting charging myself using the schedule - in short based on your response, there is no ability to report costs with this app and it’s evidently no where near as good or as intuitive as the original Monta app. I have no choice but to struggle on without until such a time as the additional features are added, whenever that is!

Edit - I will try out what you have said although I am on Next Smart Saver Fixed - (triple rate tariff) There is only option for single and dual rate from what I can see if trying to do manual.

Response from developer

Hi. What tariff are you on please? In the mean time, in Tariff Sense you can input your rates manually. Even if you use manual charging, as long as your rates are in Tariff Sense then the charge history will show previous charges and their cost.

Useless App

Used this app on my newly installed Sync Energy 2 wall charger, app always errors when looking for firmware updates (Monta found it and installed it), schedule was set in the app and it started 4 hours early and no matter how many times I cancelled it on the app it just continued or restarted, ended up using the car to disconnect, I even removed all the schedules and it still continued to charge, installed Monta and everything worked fine…, not a great experience for a new EV user

Response from developer

Hello, we are sorry for the frustration with the firmware error and your charging schedule. Our engineers are currently working on a fix for the update issue. The scheduling problem likely happened because the charger was in "Plug and Charge" mode rather than "App Mode." When "Plug and Charge" is active, the unit starts charging as soon as it is plugged in, which overrides any schedules you have set in the app. This is why the charge continued even after you removed your schedules. We are looking into adding a clearer warning in the app to prevent this confusion for other users. If you need a hand adjusting your settings, please contact our technical support team (details in the app). Best, The Sync Energy Team

Well it seems ok…..

This new charger replaced the original which Sync EV did free of charge, which was most unusual. A free upgrade m? Unheard of. Not as visually attractive as the one it replaced but hi ho. If it works as well as the old one I shall be happy.

Response from developer

Thanks for your feedback. We are glad you are happy with the replacement. These newer models include more accurate energy metering to align with updated UK legislation. This ensures your charger is future-proofed for potential (and completely optional) smart-grid services that help balance national energy demand. These features work in the background without affecting your charging speed or performance. We wanted to make sure our customers have the most up-to-date tech as we move forward. Enjoy the new charger!

Sync Energy - Great Customer Service

I recently received an upgrade of my EV Charger from Sync Energy everything was arranged with great efficiency and the new EV Charger and improved App are brilliant … Well done Sync Energy😊👍5*****

We’re so happy you’re happy! Thanks for your feedback 🙂

Junk charger

Charger just not charging today, both our cars need charging and this ain’t working, their tech support is worse than useless and only open short hours mon-fri, no good to me on a Saturday.
Bring back the old charger and app, that was flawless

New to me

First time with electric car, find the charging good and would recommend the synch charger. This is far cheaper than using fuel especially at today’s prices.

We're super glad you are enjoying the experience. Please feel free to get in touch in case you have any questions. app.support@sync.energy

Useful app

I have been using this app for a few weeks and it functions well so far.
What would be useful is to be able to have the ability to set more than one scheduled charge time as with some tariffs there are more than one off peak slot in the 24 hours.
I just have to remember to go into the app at the allotted time and manually turn the charger on and off if I need more charge.

Thanks for the reply.
I look forward to further updates and tweaks.
Would you consider a dedicated lock/unlock cable button as an addition to the charge/schedule screen?

Response from developer

Hi and thanks for your feedback, which is very helpful. I can assure you that this will be discussed amongst the team, and there's a chance it will be added to our roadmap, if it has not already. This app just had it's first birthday and we plan to add many new features during 2026!

Technical Help

Great help from Chris in technical

Fantastic customer support

I was having some issues with our home charger, contacted technical support customer service. They answered within minutes and after speaking to a lovely person who directed me step by step, we were able to resolve the issue. Fantastic service overall

Response from developer

We're so glad we were able to resolve your issues, and thanks for your 5 star review!

Just a little idea

All works well but the cable lock should be on the main charger page not in the settings

Response from developer

Thanks for your review. No idea is too little. Can't make promises, but we will discuss it with the UI designers.

New to EV

Was recommended this charger by my electrician…..simple but effective. App is easy to set up. Excellent all round.

Mv Installations

Easy to install and set up

Do not do latest Update 25/12

All working fine until the latest update and now not working at all. Tried deleting and reinstalling app, still doesn’t work. Won’t talk to charger at all. Was fine on the last version of the App. Useless and is now going to cost us money as we won’t be be able to charge on our off peak tariff and will need to use a local charger.. Merry Bloody Christmas!! Thanks Sync Energy.

Response from developer

We hope everything is up and running now and that was a temporary problem. Please do call our tech support line in case of further issue.

App initially worked ok then just won’t connect to WiFi

Was initially working fine… now the app won’t connect to internet,,

Unit itself still has solid blue light which I believe means it’s connected.. but app says otherwise

Have to wait up to set if manual charge until my cheap rate kicks in..

Have went through all the suggested steps many times

Just poor

A useless app

I just got Sync Energy EV CHARGER installed and downloaded this app. Other than connecting to the device, this app is absolutely useless and doesn’t provide any other useful functionality. This needs to be updated .

Disaster

Keeps on crashing. Won’t open up consistently to show options. Now can’t charge car as the charger cuts off after 2 minutes. Tearing hair out
