Charges without tripping anything
Load management measures total demand and modulates charging current, so the car charges alongside the shower and oven instead of competing with them.

The service
The charger is simple; the supply behind it is the actual job
An EV charge point is a dedicated circuit with its own protection, a suitable earthing arrangement, and a unit that can manage its draw against the rest of the property's demand. Fitting the unit takes a few hours. Getting the supply confirmed and the circuit and protection right is what decides whether the installation is safe and reliable.
Load management is the part most often skipped. A 7kW charger is a big continuous load, and on a property with an electric shower, an oven and a heat pump the total can approach the incoming supply capacity. Load-managed installations monitor demand and cut charging current when the house draws heavily, so nothing trips and no supply upgrade is needed.
Because we install automation and solar too, chargers get set up to be genuinely useful. Scheduled into cheap overnight tariff windows, or driven by surplus generation, and visible in the same system as your heating and lighting.
Who this is for
- Homeowners in Derby and Derbyshire installing a first home charge point
- Properties with off-street parking where cable routes need planning
- Households with solar or a battery wanting charging driven by surplus generation
- Homes on time-of-use tariffs wanting charging in cheap overnight windows
- Workplaces installing single or multiple charge points
What it costs to leave it
A charger fitted without checking the supply is a problem waiting for a cold morning
Charge points installed without a load assessment cause predictable trouble. The main breaker trips when the shower, the oven and the car all draw together, usually on a winter morning. Occupants respond by charging overnight only and treating the daytime as off-limits, a workaround for an installation nobody assessed properly in the first place.
Earthing is the safety-critical detail. Charge point installations need specific earthing arrangements, and getting it wrong on certain supply types creates a real shock risk during a fault. It's not visible and it won't show up in normal use, which is exactly why proper installation and certification exist.
The lesser cost is missed savings. A charger with no tariff scheduling charges whenever it's plugged in, often through the most expensive part of the day. One with no link to solar exports generation while buying electricity to charge the car at the same time. Both are configuration issues, and both are easily avoided.
Mistakes we get called out to fix
- Installing a 7kW charger without assessing the incoming supply capacity
- Skipping load management and relying on the household to avoid coincident loads
- Incorrect earthing arrangements for the supply type at the property
- Undersized or unprotected cable on long runs to a detached garage
- A charge point sited where the cable won't reach the vehicle's port comfortably
- No tariff scheduling and no solar link, so charging happens at the worst price
How the job runs
A fixed sequence, so nothing
gets decided on the fly
-
01
Free assessment
We check the incoming supply, the consumer unit, the earthing arrangement, the parking position and the cable route, and confirm what the property can support.
-
02
Design and quotation
Circuit design, protection, load management strategy, unit selection and mounting position, with a written quote and clear scope before work begins.
-
03
Install
Dedicated circuit run and protected, earthing arrangement installed correctly for the supply type, unit mounted and cable route made tidy and weatherproof.
-
04
Test and certify
Full electrical testing, protective device verification, load management proved under real conditions, and certification issued and notified.
-
05
Configure and hand over
App set up, tariff scheduling configured, solar or automation integration enabled where present, and the whole thing demonstrated before we leave.
What you actually get
Measurable outcomes, not adjectives
Charging at the cheapest rate
Scheduling into overnight tariff windows means the vehicle charges when electricity is cheapest, automatically, with no timer to set each evening.
Uses your own generation
Where solar is installed, charging can follow surplus generation, so daytime output charges the vehicle instead of being exported at low value.
Correct earthing, verified
The earthing arrangement is designed for your supply type and proved during testing, which is the detail that separates a compliant installation from a risky one.
Neat, weatherproof installation
Cable routes planned and finished properly, with the unit positioned so the lead reaches the vehicle's port without stretching across a driveway.
Certified and guaranteed
Certification issued and notified through NAPIT, with a 6-year workmanship guarantee on qualifying installation work.
In detail
Supply capacity, load management, siting and workplace installations
Charge point installations are governed by the supply behind them. Here's what we assess for homes and workplaces across Derby, Derbyshire and Nottinghamshire.
Supply, protection and earthing
Every installation starts with what the supply can deliver and how the property is earthed. These checks determine the circuit design and, occasionally, whether a supply upgrade needs discussing with the network operator.
- Incoming supply capacity and main fuse rating verified before design
- Consumer unit spare capacity assessed, or a new way and protection provided
- Earthing arrangement designed for the supply type present at the property
- Correctly rated protective devices for the charge point circuit
- Cable sizing calculated for the run length, including detached garages
- Full testing, certification and notification through NAPIT registration
Load management and tariffs
Load management lets a substantial charging load coexist with everything else on a domestic supply. Tariff scheduling is what makes it cheap.
- Whole-property demand monitoring with dynamic charging current adjustment
- Scheduled charging into cheap overnight tariff windows
- Solar surplus charging where generation is installed
- Battery storage coordination so the car doesn't drain the house battery
- Multiple charge points balanced across a single supply where required
Siting and cable routes
Position determines whether the installation is pleasant to use day to day. Charging cables are short, heavy and awkward, and a unit in the wrong place is a daily irritation.
- Unit positioned for the vehicle's charge port and normal parking orientation
- Tethered and untethered options discussed against how you actually park
- Weatherproof external installation with tidy containment and correct glanding
- Armoured supplies to detached garages, carports and driveway positions
- Lighting at the charging position where the area is dark, linked to automation
Domestic versus workplace
Workplace installations add access control, usage recording and the need to balance several charge points against one commercial supply.
- Domestic: single point, load-managed, tariff-scheduled, integrated with solar
- Workplace: multiple points with dynamic balancing across the site supply
- User authentication and usage recording for staff, fleet and visitor charging
- Groundwork, containment and bollard protection in car park environments
- Installation phased around trading hours with RAMS issued on request
Before you enquire
EV charger installation questions,
answered straight
How much does EV charger installation cost in Derby?
It depends on the unit chosen, the cable run length and whether the consumer unit has spare capacity. We don't publish prices, but the assessment is free and you get a written quote before work starts.
How long does installation take?
A straightforward domestic installation is usually done within a day. Long runs, board changes or workplace installations with multiple points take longer and are quoted with a duration.
Do I need my supply upgraded?
Usually not. Load management lets a charger work within an existing supply by reducing charging current when household demand is high. We confirm this at the free assessment.
Can the charger use my solar generation?
Yes, where solar is installed. Charging can follow surplus generation so daytime output goes into the vehicle instead of being exported at low value.
Tethered or untethered, which is better?
Tethered is more convenient day to day; untethered is tidier and more flexible across different vehicles. We'll talk through how you park and which suits you.
How long does a charge point last?
Charge points are designed for years of outdoor service. The connector and cable are the wearing parts on tethered units, and both are replaceable without changing the whole installation.
Can you install a charger at a business or car park?
Yes. Workplace installations including multiple points, dynamic load balancing, user authentication and usage recording are all within scope.
What certification do I receive?
Full electrical certification for the new circuit, notified through our NAPIT registration, along with test results for the installation.
What guarantee applies?
Qualifying installation work carries a 6-year NAPIT-backed workmanship guarantee, with a minimum one-year guarantee on other work. The charge point carries its own manufacturer warranty.
Which areas do you cover?
Derby, Duffield, Belper, Ilkeston, Long Eaton, Ripley, Ashbourne, Matlock, Burton upon Trent, Nottingham, Chesterfield, Sheffield and the surrounding East Midlands.
