If you’re searching for home EV charger installation because the granny charger is getting old fast, this guide keeps it practical and local to Rutland. We’ll cover what size charger you really need (7 kW vs 22 kW), how smart charging rules work, the basics of earthing and safety, how cabling routes affect price, and what to know about grants and permissions. Where it helps, you’ll find links to relevant pages on our site so you can book a survey or explore related upgrades.
The quick version
-
Most homes choose a 7 kW smart charger – fast enough for overnight top-ups on common EVs without three-phase electrics.
-
Smart charging is the norm – schedules, solar-matching and load-balancing protect your main fuse and your tariff.
-
Cabling and location drive cost – a neat, short cable run to the desired parking spot keeps budgets happy.
-
Grants & paperwork – we’ll advise if you’re eligible and handle notifications so everything is signed off properly.

7 kW vs 22 kW: what actually suits your home?
7 kW single-phase is the sweet spot for most Rutland homes. It adds ~25–30 miles of range per hour depending on the car – plenty for overnight charging. 22 kW requires three-phase supply; most homes are single-phase, so upgrading rarely makes financial sense unless you’re doing major electrical works anyway.
During your survey we’ll confirm your supply type, main fuse rating, and spare capacity. You’ll see the options laid out clearly on our Domestic EV Charging page before we recommend a unit.
Smart charging: schedules, load management & app control
Modern chargers do much more than push electrons:
-
Charging schedules let you target cheaper off-peak windows (typically overnight), so you wake up full without paying peak rates.
-
Dynamic load management watches your whole-house demand and automatically slows the car if the oven, shower and heat pump all kick in—protecting your main fuse.
-
Insights & controls in the app show cost per kWh, kWh added per session, and let you start/stop remotely. It’s also handy if you share the driveway and want to track usage.
If you’re already planning solar or batteries, our team will set up smart rules so the charger prioritises surplus solar when the sun is out and flips to off-peak grid overnight. Learn more about pairing with PV on Domestic Solar and Domestic Battery Storage.
Cabling: the part that quietly sets the budget
The charger itself is one line on the quote; the cable route is usually the decider. We always aim for the neatest, shortest run that keeps the charger exactly where you want the cable to reach the car comfortably.
What we’ll check on survey:
-
Consumer unit location (fuse box) and whether we can route internally, externally, or via loft/void.
-
Wall type & fixings – brick, stone, render; we make fixings tidy and sealed.
-
Driveway layout – where the car usually parks and where the cable will naturally hang.
-
Penetrations & protection – if we go underground, we specify correct ducting and depth; if surface-mounted, we use tidy containment.
Safety & compliance (the stuff you don’t want to guess on)
A quality install is quiet, safe, and signed off. We handle:
-
Earthing & PEN fault protection so the charger is safe even during rare supply faults—no earth rods where not suitable, and correct integrated protection if required.
-
RCD/RCBO selection matched to the charger’s internals (Type A/F/B as appropriate).
-
Notification and certification so your paperwork is complete once the job’s done.
You’ll get a clear handover explaining how to use the charger, set schedules, and what to do if you change car or tariff. If you later add PV or storage, we can revisit the settings so everything works as one system – start that conversation via Contact Us.
Grants & allowances: what might apply
Grant rules do change over time, but as a rule of thumb:
-
Homeowners in single-unit private dwellings often won’t qualify unless specific criteria are met.
-
Flat residents and landlords sometimes have routes to support; we’ll flag this during your quote.
-
Business vehicles or mixed-use properties may have different options.
The easiest path is to ask us during the survey—we’ll confirm what’s available for your situation and bake it into the quote so you know the net cost from the start. Begin here: Domestic EV Charging.
Solar now or later? How to future-proof your charger
If solar is on your horizon, we’ll either:
-
Install a charger that talks to PV from day one, or
-
Fit a PV-ready unit you can switch into solar-matching mode when your array goes live.
Some homeowners also add a small battery just to capture late-afternoon sun for an evening top-up. We’ll model solar-only vs solar-plus-battery and show the cost/saving trade-offs. When you’re ready to explore, head to Domestic Solar and Domestic Battery Storage.
Tethered or untethered?
-
Tethered gives you a permanently attached cable (typically 5–8 m). Super convenient, just unhook and plug in.
-
Untethered looks minimalist and uses your car’s portable Type 2 cable. Great when you want a clean facade or you share the space with another EV type.
We’ll recommend based on where you park, how often you charge, and whether you prefer form factor or convenience.
Installation day: what actually happens
-
Pre-arrival checks – We confirm your chosen location, walk the cable route, and finalise fixings.
-
Consumer unit & protection – We add the correct protective device(s) and any required isolator.
-
Charger mounted & wired – Level, sealed, and labelled; we keep containment tidy and consistent.
-
Testing & commissioning – Live tests, app pairing, firmware updates, and dynamic load management setup.
-
Handover & training – We set your first schedules together and show you how to override for ad-hoc top-ups.
-
Paperwork delivered – You’ll receive your certificates and a simple aftercare guide. If you want ongoing support.
Most straightforward installs are completed the same day. More complex routes or consumer-unit upgrades may take longer – we’ll flag that clearly in your quote.
How to reduce running costs from day one
-
Use off-peak schedules – set and forget; your car will be full by morning.
-
Match solar when possible – daytime top-ups from your roof are hard to beat on cost.
-
Keep connectors clean & dry – a quick wipe before plugging in is simple preventative care.
-
Name your schedules – “Weeknights,” “Sunday Long Charge,” etc., so you can tap the right one without thinking.
If you’re already planning energy upgrades (heat pump, solar, battery), tell us. We’ll size and set up the charger so everything plays nicely together.
FAQs we hear around Rutland
Do I need three-phase for a decent charge speed?
No. A 7 kW single-phase unit is ideal for most homes and cars. Three-phase (22 kW) is rarely necessary domestically.
Can you install in a detached garage or barn?
Yes, just factor in the cable route. If trenching is needed, we’ll specify ducting and reinstatement so it’s robust and tidy.
Will the charger work if I change car later?
Absolutely. Type 2 is standard across modern EVs. If you change from PHEV to full EV, we can revisit schedules and load settings with you.
What happens in a power cut?
The charger stops safely. When power returns, most units resume scheduled behaviour automatically.
Can I limit others from using it?
Yes, PINs, RFID cards, or app-only activation are available on many models.
Next steps
If you want a quote that reflects your driveway, consumer unit and cabling route, not a generic bundle, book a quick survey. We’ll spell out the neatest install plan, confirm any grant options, and show how to integrate with solar now or later.
