Your questions, answered.
From choosing a charger to your first charge and beyond.
Clear answers from the team installing it.
Before installation
A little planning. A smooth installation.
Choosing your charger & installation
What is included in a standard EV charger installation?
Our standard installation includes up to 10 metres of supply cable, surge protection, the electrical protection specified in your quotation, mounting, testing, commissioning and a customer handover.
Load balancing is included with chargers that provide it as standard. Your quotation confirms any additional equipment or work. The supply cable is separate from the charging lead that plugs into your car.
Which EV charger is right for my car and home?
We help you compare chargers based on your vehicle, parking space, cable reach, tariff and the features you want. Tell us about existing or planned solar panels, battery storage or a second EV so we can take these into account.
How fast will my car charge at home?
Most single-phase home installations provide up to approximately 7.4 kW. Actual power depends on your vehicle, electrical supply and any configured charging limits or load management. Three-phase charging requires both a suitable supply and a compatible vehicle.
Can you install a charger I have bought myself?
Yes. Send us the exact make and model before we quote, and have the charger and required accessories available for installation. We will assess its suitability. The product warranty is separate from our installation warranty.
Quotes, surveys & cable routes
Is my installation quotation a fixed price?
Yes. The price covers the agreed installation plan, based on the information and photographs assessed by our team. Please tell us if anything changes. If a changed scope or unexpected condition requires different work, we will explain and agree any additional cost in writing before that work proceeds.
Do I need an in-person survey?
Most installations can be assessed remotely using photographs and descriptions. We have completed thousands of installations this way. In-person surveys are available in certain circumstances at £288 including VAT (£240 plus VAT), agreed before booking.
Will the cable be visible, and can you hide it?
The route depends on your property. Cables may be clipped neatly to external walls, installed in surface trunking or run through accessible concealed spaces. Tell us your preferences during assessment. Your installation plan describes the agreed route.
Can you reuse an existing cable or garage supply?
Sometimes. We need certification for the existing installation and must assess suitability, including inspection and testing on the day. Correctly installed EV-specific cables may be reusable. A nearby garage consumer unit does not automatically provide a suitable connection.
Your electricity supply
Can I install an EV charger with a 60 A main fuse?
A 60 A fuse does not automatically prevent installation. We assess household demand, supply condition and the charging arrangement. Load management or a reduced charging limit may be appropriate; some properties need supply work or DNO approval first.
What is load balancing, and is it included?
Dynamic load balancing monitors electricity use and adjusts charging to stay within a configured supply limit. It is included where the charger provides it as standard. Other models require additional equipment, which your quotation will identify.
What is a DNO, and why might approval be needed?
Your Distribution Network Operator manages the local electricity network. It is usually different from your energy supplier. We assess whether prior approval or notification after connection is appropriate. Where prior approval is required, it must be received before connection.
Grants, payment & booking
Can I get a grant for a home EV charger?
Eligible renters and flat owners may receive 75% of eligible costs, up to £500. Eligibility depends on the property, parking, vehicle and scheme conditions. Tell us before accepting a quotation or booking so we can identify the appropriate application route.
Can I claim the Workplace Charging Scheme at my home address?
You may qualify if your home is your primary workplace and its address is listed as your place of business with Companies House or recorded on your business rates bill. Registration alone does not guarantee approval.
The grant covers up to 75% of eligible costs, capped at £500 per socket, for up to 40 sockets across an applicant's sites. You need suitable off-road parking, an authorised installer and a charger eligible for residential and commercial use. Other conditions apply.
Workplace Charging Scheme guide ↗When and how do I pay Elecology?
For direct bookings, we do not ask for upfront payment. We normally email your invoice the week after installation, with bank-transfer details. Payment is due within seven days of receiving the invoice.
Can I change or cancel my appointment?
Contact us as soon as possible and give at least seven days' notice if you cannot attend. Missed appointments carry a £55 administration fee including VAT. Applicable statutory cancellation rights remain unaffected.
More planning questions
What is the difference between a tethered and an untethered charger?
A tethered charger has a permanently attached charging lead. An untethered charger has a socket for a separate cable. Tethered models are convenient for everyday use; untethered models allow the cable to be stored separately. We can help you choose a suitable model and cable length.
How long will it take to charge my car?
Charging time depends on how much energy you need to add and the actual charging power. Adding 35 kWh at a steady 7 kW takes approximately five hours before charging losses or changes in power. Most drivers top up rather than charge from empty.
How much does an EV charger installation cost?
The cost depends on the charger, cable route, distance from the supply and additional work. We assess your property and provide a quotation for the agreed installation. It identifies who supplies the charger and the total price including VAT.
What can make an installation more expensive?
Longer routes, internal trunking, groundworks, detached garages, pedestals and specialist access can increase costs. Existing electrical defects or supply alterations may need addressing. We aim to identify requirements during assessment and include them in your quotation.
What photographs do you need for an installation quote?
We normally need clear photos of the meter, main fuse, consumer unit and wider supply area; your preferred charger position and parking; the route between them; and any existing charger, solar or battery equipment. Photos from further back and simple floor plans help us understand the layout. Do not remove electrical covers or expose live equipment.
Where can my EV charger be installed?
We assess the mounting location, safe access to your vehicle, charging-lead reach, supply-cable route and required permissions. Send a photo of the whole parking space and preferred position. We can assess a pedestal where wall mounting is unsuitable.
Can my electrician or builder prepare the cable route?
Yes, provided the work and specifications are agreed with us first. We can confirm requirements for power and data cables, ducts and access. Correctly installed EV-specific cables may be reusable following assessment. Check with us before purchasing materials or concealing work.
Why might my charger need a separate data cable?
Some chargers use a data cable to communicate with equipment monitoring household demand or solar generation. This is different from Ethernet internet access. Requirements depend on your charger and installation and will be identified during assessment.
Why does the charger need dedicated electrical protection?
EV charging places a sustained load on the supply. The circuit needs protection appropriate to the installation. Built-in charger safety features do not replace every protective device needed for the supply circuit. We specify the required circuit protection, surge protection and supply-fault protection.
What is open-PEN protection?
Open-PEN protection is a safety measure used in certain installations to detect a particular electricity-supply fault and disconnect the charger when required. We assess the appropriate protection and earthing arrangement for your property.
Is surge protection included?
Yes. Surge protection is included in our standard EV charger installation. It helps reduce the risk of damage from short-duration voltage surges. It does not protect against every electrical fault or guarantee that equipment can never be damaged.
What is a looped electricity supply?
A looped supply is an arrangement where neighbouring properties share part of the incoming electricity service. The DNO may need to assess it and arrange alterations. We will explain the conditions the DNO gives us, including whether connection is permitted before supply work.
Who arranges a main-fuse upgrade or other supply alterations?
The DNO normally deals with the incoming service and main fuse; your energy supplier may need to arrange metering work. We can explain who to contact. Availability, timing and charges for external supply work are determined by the responsible organisation.
What is an MPAN, and where can I find mine?
Your Meter Point Administration Number identifies your electricity supply point and differs from the meter serial number. Find it on your electricity bill, often in a Supply Number box. We need its 13-digit core number for network applications. Your supplier can help locate it.
Can you install at a rented home, flat or allocated parking space?
Potentially, yes. We assess the parking, supply, route and permissions. You may need consent from a landlord, freeholder, managing agent or landowner. An allocated bay does not automatically give permission to run cables across surrounding land. Tell us about shared areas before we quote.
Does my grant need approval before installation?
For a grant-supported booking, the required approval must be in place before installation. An application reference or voucher does not confirm every requirement has been met. Provide accurate details and requested evidence promptly. Approval times are outside our control and may affect booking. Your quote identifies any grant deduction.
Will my charger work with solar panels or a home battery?
Many chargers can be installed at homes with solar or battery storage. Available features depend on the equipment and its connections. Send details of your inverter, battery, gateway and monitoring. Solar-only charging, energy monitoring and avoiding battery discharge are separate requirements to assess.
Can I use a cheap EV tariff or charge only from surplus solar?
These are separate features. A tariff may use a schedule or integration with a compatible vehicle or charger. Solar-only charging needs suitable equipment and monitoring. Tell us your requirements before choosing a charger. Your energy supplier confirms its current tariff eligibility and compatibility.
Does the charger need Wi-Fi?
Connectivity requirements vary. Internet access may be needed for apps, updates, remote support or tariff integrations. Check coverage at the charger position and have network details ready. Tell us about poor signal in advance so we can discuss supported options.
How do I accept my quotation and book an installation?
Follow your quotation’s acceptance instructions or contact us to proceed. We check outstanding requirements, including DNO or grant approval where needed, and arrange a date. Rely on Elecology’s confirmation for the agreed appointment details.
Tesla: will my Wall Connector integrate with Powerwall and solar?
We assess your Tesla equipment, electrical connections and requested features. Seeing charging activity in the app, including charging in household measurements and controlling battery use are separate requirements. Tell us what you want to achieve so we can confirm the proposed arrangement.
Tesla: can I avoid draining Powerwall and charge during a power cut?
These requirements need assessment because connections and system controls affect both battery use and outage operation. Send your Powerwall and Gateway models and explain whether backup charging is essential. Do not assume a standard installation includes outage charging or prevents battery discharge.
During installation
Know what to expect on the day.
What time will the engineer arrive?
Your Elecology confirmation gives a start time or arrival window. If another platform shows different details, follow Elecology's confirmation or contact us to check.
How long does installation take?
A typical installation takes around three to four hours. Complex cable routes, electrical work and commissioning can take longer. Your engineer will discuss the plan before starting.
Do I need to be home?
An authorised adult must attend approximately the first 15 minutes to agree the work and the last 15 minutes for handover and sign-off. They need not be the principal driver, but must be able to approve the work and receive the demonstration.
What should I prepare before the engineer arrives?
Clear access to the supply, cable route and mounting position. Complete the preparation in your installation plan. Have any customer-supplied charger, Wi-Fi details and required app account available.
Will my electricity be switched off?
A temporary interruption is normally needed to connect safely. The engineer will explain the expected timing. Tell us in advance about medical or other essential equipment that needs special arrangements.
What if the installation cannot be completed?
We will explain the problem and the work or action required. Where circumstances beyond our control prevent completion, including access issues or incorrect site information, reasonable costs may apply, with a minimum fee of £55 including VAT.
More questions about installation day
Does my electric car need to be there?
Having the car available helps us demonstrate charging and check the complete experience. Tell us before the appointment if it will not be there. We can explain the commissioning and handover possible and anything to check when it arrives.
Will the engineer confirm the cable route before starting?
Yes. The engineer reviews the agreed plan with the person attending before work starts. Confirm the position, visible route and accessible alternatives then. Concealed routes must be suitable and accessible. Any change affecting price must be agreed before the additional work.
Will you set up the charger and show me how to use it?
Yes. Commissioning and handover are included. We demonstrate the charger and help with supported setup using the account and connection available. If connectivity, account or manufacturer issues prevent a feature being set up, we explain what remains and the next step.
After installation
Ready to charge. Here when you need us.
When will I receive my electrical certificate?
We email your Electrical Installation Certificate within 25 days of installation. If it has not arrived, check your junk folder and contact us. Applicable Building Regulations documentation is separate.
Why is my car charging slowly or pausing?
Vehicle settings, schedules, household load management and tariff controls can affect charging. Check the messages in your charger and vehicle apps. For help, share the models, charging power and any error message.
Should I contact Elecology or the manufacturer?
If the charger has power but a product, app or software fault, start with the manufacturer. If it has no power, contact Elecology. We work closely with manufacturers and can help coordinate investigation.
What warranty covers the installation?
Our installation warranty lasts three years from completion and covers defects in workmanship or materials, including necessary labour and attendance for covered defects. It excludes tampering, misuse, user error, environmental damage and normal wear and tear.
Report suspected defects promptly with details and photographs. We may inspect the installation to determine the appropriate repair or replacement. Your statutory rights are unaffected.
Will I have to pay for a call-out?
Remote assistance is the first step. Costs depend on the cause, work required and warranty cover. Attendance for covered installation defects is included; charges for other work are explained before agreeing a paid visit.
Does my EV charger need servicing?
We recommend annual servicing at £178.80 including VAT per socket. This includes visual inspection, connection and cable checks, protective-device testing and a functional charging test.
Follow the manufacturer's instructions between services. Our recommendation is separate from any manufacturer warranty conditions.
More charging & support questions
Can I start charging straight away?
Normally, yes, after testing, commissioning and handover. The engineer explains any charging limit or outstanding restriction. Charging also depends on vehicle settings, schedules, account setup and tariff controls.
How do I set charging schedules and use my EV tariff?
Use the method supported by your charger, vehicle or energy supplier. Avoid conflicting schedules in several apps. For supplier-managed charging, follow its setup instructions and check the correct charger or vehicle is linked.
What does waiting for a schedule mean?
It usually means a schedule or control has not yet authorised charging. Check your charger, vehicle and energy-supplier apps. This does not automatically indicate an installation fault. The manufacturer or tariff provider can identify the control holding the session.
What should I do if my EV charger stops working?
Record the error message or light pattern and whether the charger has power. For a powered charger, the manufacturer is usually best placed to investigate product or app faults. For no power, contact Elecology. Do not remove electrical covers or repeatedly reset protection that trips. Stop using damaged, unusually hot or burning equipment and seek assistance.
What if the charger loses Wi-Fi or I change my router?
Reconnect using the manufacturer’s instructions. Effects on charging and features vary by model. Start with manufacturer support for connection and app help. If extra connection equipment or installation work is needed, we can assess it and explain costs before arranging a visit.
What warranty covers my EV charger?
The manufacturer’s standard warranty applies, with terms and periods varying by product. Extended product warranties are between you and the manufacturer; they do not extend our installation warranty or automatically include installation work or attendance. Your statutory rights are unaffected.
How do I stop someone else using my charger?
Access controls vary. Some models have app restrictions, vehicle permissions, locking or authorisation settings. Tell us if access restriction matters before choosing. For existing equipment, ask the manufacturer which settings are supported.
Can I use the same charger if I change my car?
Often, yes, if compatible. Check connector type and any vehicle-specific tariff or app integration. The new vehicle may charge at a different speed. Send us the make and model if unsure.
What if I add solar panels, a battery or another charger?
Tell us before installation so combined demand, monitoring and controls can be assessed. Extra equipment can change the existing configuration. A second charger may require more capacity or power management. Solar and battery integration may need monitoring or work by the original system installer.
