It is adding a dedicated circuit that will run at or near its rated load for hours at a time, several nights a week, for years. That places demands on the consumer unit, the cable, the protective devices and the earthing arrangement that a socket circuit never sees. The work covers assessment of the incoming supply and existing load, selection and positioning of the unit, the cable route from board to charge point, the protective devices required for outdoor equipment, earthing arrangements appropriate to the supply type at your property, and full testing and certification of the finished circuit. Done properly, you stop thinking about it: the car plugs in, charges during the hours you have chosen, and the installation does not interact badly with the shower, the oven or anything else in the house. Done badly, it becomes the circuit that trips the board on winter evenings. ### Who it is for New and prospective EV drivers, households replacing a second car, landlords adding charging to a rental, and homeowners future-proofing during a renovation. ### When to install Ideally before the vehicle arrives, and always during a rewire, driveway works or an extension while cable routes are still open and cheap. ### What is assessed Supply type and capacity, existing demand, board condition and spare ways, earthing and bonding, cable route length and method, and parking position. ### Why professional installation matters Charging is a sustained high load outdoors. Protection, earthing and cable sizing are what stop that becoming a heat, shock or nuisance-tripping problem. ## What goes wrong when it is done cheaply Charge point failures rarely happen on the day of installation. They emerge in the first cold winter, when the house is drawing everything at once and the circuit is running for six hours a night. ### Charging from an ordinary socket A standard 13A socket and its circuit were designed for intermittent loads, not for hours of continuous draw. Sustained charging through an unsuitable socket, an extension lead or an old spur is a known cause of overheated accessories and damaged cable. ### Ignoring available capacity Adding a 7kW load to a property already running an electric shower, oven and hob without assessing total demand produces exactly the outcome you would expect: main protection tripping on the evenings when everything runs together. ### Wrong earthing arrangement outdoors Outdoor charging equipment has specific earthing requirements depending on the supply type at your property. Getting this wrong creates a shock risk that is entirely invisible in normal operation and only matters at the moment a fault occurs. ### Headline price, then extras A quote that excludes the cable run, the board work and the making-good is not a quote, it is an opening bid. Homeowners routinely discover the real figure once the installer is already on the driveway and the job is half open. ### No certification, problems later An uncertified circuit is a question mark on the property. It surfaces at insurance, at sale, and at any subsequent inspection, and retrospective testing on buried cable is far more expensive than testing it before the trench was filled. ## How we install a charge point - 01 ### Survey and load assessment We check the supply type, the incoming capacity, the existing demand, the board condition and the earthing arrangement, then confirm the practical cable route and mounting position with you. - 02 ### Specification and written quote You get a recommendation on tethered or untethered, the charge rate that suits your supply and usage, any board or bonding work required, and one itemised no-obligation price. - 03 ### Installation Dedicated circuit run from the board with the correct cable type for the route, clipped, ducted or buried with warning tape, the correct protective device, and the unit mounted where the lead reaches the car without crossing a walkway. - 04 ### Testing and verification Continuity, insulation resistance, polarity, earth loop impedance and residual current protection are tested and recorded, and the unit is exercised with an actual charge cycle rather than a power-on check. - 05 ### Configuration and scheduling Charging is set to your off-peak window, connected to the app or home system where applicable, and where the property has automation we tie it into wider energy control. - 06 ### Handover, certification and guarantee You receive the certification, a demonstration of the unit, and clear detail on the manufacturer warranty covering the equipment plus our cover on the installation work. ## Why it is worth doing properly ### Cheaper charging Scheduling into your off-peak window is the single largest saving available, and it only works if the installation supports it. ### Safety under load Correctly sized cable, the right protective device and valid outdoor earthing, tested rather than assumed. ### No nuisance tripping Load assessed against real household demand, so charging does not fight the shower and the oven on a winter evening. ### Longevity The cabling and protection outlast the unit, so a future charge point upgrade is a swap, not a reinstall. ### Integration Tariff-aware and, on Loxone properties, coordinated with the rest of the home's energy use. ### Evidence Certification for the circuit, filed and ready for insurers, buyers and future inspections. ## Specification detail that changes the job Two installations on the same street can be very different jobs. These are the variables that decide the scope, the price and the eventual charging experience. ### Charge rates and supply type A 7kW single-phase unit is the standard domestic choice and replenishes a typical battery comfortably overnight. Slower 3.6kW units make sense only where supply capacity is genuinely constrained, and faster three-phase units are relevant to the small number of homes with a three-phase supply already present. Load management matters more than raw speed. A charger that can modulate its output against the property's total demand lets you keep a higher charge rate without upgrading the supply, because it backs off when the rest of the house needs the capacity. ### Cable routes and installation methods Short internal runs from a garage board are the simplest case. Runs across an external wall are clipped or ducted in UV-stable containment; runs to a detached garage or a parking position across a driveway are made in steel wire armoured cable, buried to depth with warning tape above and terminated in a weatherproof gland. Route length drives cable size, because voltage drop over a long run has to stay within limits at full load. This is one of the main reasons a driveway-length run costs more than a garage-wall installation, and the main reason a cheap quote that ignores the route cannot hold. ### Protection and earthing EV circuits require residual current protection appropriate to the DC leakage that charging equipment can produce, provided either within the charge point or by the protective device in the board. Which of those applies depends on the unit chosen, and it must be verified rather than assumed from a datasheet headline. Earthing arrangements for outdoor equipment depend on the supply type present at the property. Some installations require an approach that avoids exporting the supply earth outdoors; many modern charge points include the protection to handle this internally. We confirm which route your property needs during the survey. ### Tethered, untethered and mounting position Tethered units keep a cable permanently attached, which is convenient but fixes cable length and connector type. Untethered units accept the vehicle's own cable, keep the wall clear and make replacement of a damaged cable trivial rather than a service call. Position is decided by where the car actually parks, which way it faces, and where the charging port sits on the vehicle. Getting this wrong produces a cable that crosses a footpath or barely reaches, which is a daily irritation for the life of the installation. ### Solar, batteries and tariff integration Where a property has solar generation, a compatible charge point can prioritise surplus export back into the car rather than importing at grid rates. This requires the right metering and a unit that supports it, and it is worth confirming before the equipment is purchased. Where the property runs Loxone, charging becomes one more controllable load alongside heating, hot water and lighting. The system can hold charging back until the off-peak period begins, or shed it temporarily when total demand peaks. ### Domestic versus commercial charging Domestic installation is a single dedicated circuit optimised for overnight charging and one or two vehicles. Commercial charging involves multiple points, load sharing across a site, access control, usage recording and often a supply capacity assessment before anything is specified. We handle both. If you are a landlord, developer or business considering multiple points, that is a commercial electrical scope rather than a domestic one, and we quote it accordingly. ## Frequently asked questions How much does an EV charger installation cost in Birmingham?The charge point itself is only part of it. Price depends on cable run length, whether the route is surface, buried or through a cavity, whether your consumer unit has a spare way and adequate capacity, and whether earthing arrangements need work. We survey first and quote a single itemised figure with no-obligation, rather than an attractive headline price plus extras on the day. How long does installation take?A straightforward installation with a short cable run is usually a single day. Longer runs, buried ducting to a detached garage, a board upgrade or supply work extend that, and we tell you which of those apply at survey rather than mid-job. Will my existing consumer unit cope with a charger?Sometimes yes, often not without change. A charger is a continuous high load, so the board needs a suitable spare way, appropriate protection and an earthing arrangement that is valid for outdoor equipment. Where those are missing we quote the corrective work up front so the total is known before you commit. Do I need a three-phase supply?The vast majority of homes charge perfectly well on a single-phase 7kW unit, which typically adds a full battery overnight. Three-phase is worth discussing only where the property already has a three-phase supply and there is a genuine reason to charge faster. Can the charger use cheap overnight electricity?Yes. Scheduling can be set on the charge point, in the vehicle, or through your home automation system so charging runs inside your off-peak window. Where the property has a Loxone system we can make charging respond to tariff periods and to what the rest of the house is drawing. Can it work with solar panels or a battery?Charge points with solar integration can prioritise surplus generation rather than importing from the grid, and we set this up where the property has the metering and inverter capability to support it. We will tell you honestly whether your existing kit supports it before you buy a unit expecting it to. How long does a charge point last?The installation, cabling, protection and mounting, has a service life measured in decades when done correctly. The charge point itself is the shorter-lived component, and installing it so the unit can be swapped without redoing the cabling protects most of your spend. Is a tethered or untethered unit better?Tethered is more convenient day to day because the cable is always there; untethered is tidier, easier to replace if a cable is damaged, and copes better with different vehicles. If the driveway is exposed to the street, untethered also removes a cable that can be tampered with. Do you certify the installation?Yes. The circuit is tested and certified as part of the work, and you receive the documentation. That record is what your insurer and any future buyer will want to see.
