A private charge point sold for home use in Great Britain has to meet the Electric Vehicles (Smart Charge Points) Regulations 2021, including smart functions that use a communications network. Those rules also expect the unit to be able to charge a car when that network is unavailable. No broadband is still a design problem: you need to know whether the off-peak schedule lives in the charger, whether a 4G option exists, and what the box does on the morning the signal fails.
The rules and the lane at the end of the install
GOV.UK explains that the 2021 regulations apply to people selling private charge points, and that smart functionality includes sending and receiving information. Selling a dumb unit from a marketplace, because the cottage has no line, can put the seller on the wrong side of those rules. The practical buyer question is different: once a compliant charger is on the wall, what works with no router in the house?
Guidance around the regulations covers continued charging if communications drop. That is not the same as keeping a clever tariff schedule. Ask, for this model, whether a lost network means the car charges straight away, follows the last saved hours, or waits until someone presses a button.
Wi-Fi that was never going to reach
A router in the middle of a stone cottage often does not serve a gable end. Fix that with a cabled access point or a mesh node if broadband exists. Do not spend the quote on a 4G plan if a short data cable would do.
If there is no broadband at all, because the line is not in yet or the house is off the network, ask whether this charger has an Ethernet port, a SIM slot or an external aerial. A SIM is a monthly cost and a coverage question. Check the network on the wall with a phone, not on the doorstep.
- Does it charge with the aerial unplugged?
- Where is the off-peak timetable stored?
- Who pays for the SIM, and what happens if the credit lapses?
- Can you start and stop a charge without an app?
Schedules, random delay and the morning you leave
Compliant private charge points use default off-peak behaviour and a randomised delay so the street does not start as one block. You can override that when you need the car now. On a site with no app access, the override has to be obvious on the unit.
Commission the charger on the driveway, not on the installer's phone hotspot, then turn the hotspot off and watch a session start. If it only works while their phone is there, you do not have a finished job.
Holiday homes and the week before the line is live
A charger installed between exchange and broadband going live still has to be safe electrically. Networking can follow. Write that split into the quote so you are not waiting for Openreach before anyone will sign the electrical certificate.
Guests in a holiday let will not debug an app. Leave a one-line instruction: plug in, press this, the car charges. A tariff schedule that needs the owner's phone is a poor fit for a house other people sleep in.
Frequently asked questions
Is a non-smart charger the legal answer if I have no internet?
No. The sale of private charge points in Great Britain is covered by the smart charge point regulations. Lack of broadband does not switch those rules off. Ask how the compliant unit behaves offline.
Will the car refuse to charge without Wi-Fi?
It depends on the model. The regulations expect charging to remain possible without the communications network. Confirm the button sequence on your unit before the installer leaves.
Is 4G reliable enough?
Only where the mobile network at the mounting point is decent. Test it. A SIM does not fix a valley with no signal.
Do I still need a smart meter?
A smart meter is about the electricity tariff, not a substitute for the charger's own connection. You can have either without the other. Off-peak billing still needs the meter the supplier asks for.
