Charges without tripping anything
Load management measures total demand and modulates charging current, so the car charges alongside the shower and the 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, an earthing arrangement suited to the installation, and a unit that can manage its draw against the rest of the property's demand. Fitting the unit takes a few hours. Confirming the supply can take it, and arranging the circuit and protection properly, is what determines whether the installation is safe and reliable.
Load management is the part most often skipped. A 7kW charger is a substantial continuous load, and on a property with an electric shower, an oven and a heat pump the total can approach or exceed the incoming supply capacity. Load-managed installations monitor demand and reduce charging current when the rest of the house is drawing heavily, so nothing trips and no supply upgrade is needed.
Because we install automation and solar as well, chargers are set up to be useful rather than just present: charging scheduled into cheap overnight tariff windows, or driven by surplus generation during the day, with the whole thing 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 and unit positioning need planning
- Households with solar or a battery who want charging driven by surplus generation
- Homes on time-of-use tariffs wanting charging scheduled into cheap overnight windows
- Workplaces and commercial premises installing single or multiple charge points
- Anyone whose existing consumer unit has no spare capacity for a charger circuit
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 proper load assessment cause predictable trouble. The main breaker trips when the shower, the oven and the car are all drawing together — usually on a winter morning when everything is running at once. Occupants respond by charging only overnight and treating the daytime as off-limits, which is a workaround for an installation that was never assessed properly.
Earthing is the safety-critical detail. Charge point installations require specific earthing arrangements, and getting this wrong on certain supply types creates a genuine shock risk during a fault condition. It is not visible, it will not show up in normal use, and it is precisely the kind of thing a proper installation and certification exists to prevent.
The lesser cost is missed savings. A charger with no tariff scheduling charges whenever it is plugged in, frequently through the most expensive part of the day. A charger with no link to solar exports generation while simultaneously buying electricity to charge the car. Both are configuration issues, and both are avoidable at installation.
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 or driveway
- A charge point sited where the cable will not reach the vehicle's port comfortably
- No tariff scheduling and no solar link, so charging happens at the worst possible 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 quotation and a 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, verification of protective device operation, 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, without anyone setting a timer each evening.
Uses your own generation
Where solar is installed, charging can follow surplus generation, so daytime output goes into the vehicle rather than being exported at low value.
Correct earthing, verified
The earthing arrangement is designed for your supply type and proved during testing — the safety 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 is what we assess and specify for homes and workplaces across Derby, Derbyshire and Nottinghamshire.
Supply, protection and earthing
Every installation starts with what the supply can actually 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 is what allows a substantial charging load to 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 does not 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. Charging cables are short, heavy and awkward, and a unit fitted 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 the 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 do not publish prices, but the assessment is free and you receive a written quotation before any work begins.
How long does installation take?
A straightforward domestic installation is usually completed within a day. Long runs to detached garages, 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 allows a charger to work within an existing supply by reducing charging current when household demand is high. We confirm this during the free assessment.
Can the charger use my solar generation?
Yes, where solar is installed. Charging can be set to 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 will talk through how you park and which suits your situation.
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 across the site supply, 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 the 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 itself carries its 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.
