7kW vs 22kW home chargers: the comparison content that wins quotes
Before a homeowner decides which installer to book, they are usually trying to decide which charger they actually need — and the "7kW vs 22kW" question is one of the most consistently searched in the whole category, by people who have not yet chosen a provider. An installer with a clear, honest comparison page captures that research-stage traffic and often earns the booking simply by being the source that explained the trade-off without upselling.
This is also a question where a little genuine expertise builds a lot of trust, because the honest answer for most homeowners is counter-intuitive — and an installer who tells them the truth rather than the more expensive option stands out.
"Isn’t faster always better?"
The honest answer most homeowners need to hear is that 22kW is usually not worth it — and often not even possible — for a typical home. A 22kW charger requires a three-phase electricity supply, which most UK homes do not have; on a standard single-phase supply, a home charger is effectively capped at around 7kW regardless of the unit fitted. An installer page that explains this plainly saves the homeowner from paying for capability they cannot use, and reads as trustworthy precisely because it talks them out of the pricier option.
"Is 7kW fast enough overnight?"
For the vast majority of drivers, yes — and saying so clearly settles a real anxiety. A 7kW charger adds roughly 25–30 miles of range per hour, so an overnight charge comfortably covers far more than the average daily drive, especially on an off-peak tariff. Framing the answer around the homeowner’s actual daily mileage, rather than abstract kilowatts, is what turns a technical spec into a reassuring "this is plenty for you" — the moment a researcher becomes ready to book a survey.
"What about three-phase and future-proofing?"
A smaller but real segment genuinely does have — or is considering — a three-phase supply, or is thinking about future needs (a second EV, a heat pump, solar and battery). Honest content that addresses when three-phase or a higher-capacity install actually makes sense, without pushing it on everyone, captures that higher-value enquiry while keeping the trust of the majority for whom 7kW is right. Installers who cover both cases clearly rank for the full range of the search, not just the common case.
Turning research traffic into surveys
A visitor reading a well-answered comparison page is, by definition, further along than someone who just searched "EV charger near me" — they have usually already narrowed the decision and are choosing between a charger spec and an installer. That makes this exactly the traffic worth a clear, low-friction next step: a "book a free survey" or "get a fixed quote" link, not a phone number buried in a footer.
