# EV Home Charger Installation: What to Expect By EV Charge Cables ยท Published 18 October 2026 **The short version** Home EV charger installation is straightforward for most owners: find an OZEV-approved installer, complete a survey visit, and the wallbox is typically fitted within one to three weeks. - The survey confirms your consumer unit capacity and cable route before any work begins - A DNO application may be needed for higher-output units, adding several weeks to the timeline - Renters and leaseholders need landlord or freeholder consent but are not excluded from home charging Getting a home EV charger installed is a straightforward process for most homeowners, typically taking a few weeks from first enquiry to plugging in your car. You will need an OZEV-approved installer, a pre-installation survey, and possibly a short wait if a DNO (Distribution Network Operator) application is required. For renters or those in leasehold flats the path is a little more involved, but it is not impossible. Explore the [full guides section](https://www.evchargecable.co.uk/blogs/guides) for related advice on getting the most from your home charging setup once the wallbox is in place.

The Office for Zero Emission Vehicles maintains a searchable register of approved wallbox installers, which you can find on the GOV.UK website. Searching by postcode returns local installers who have met the required training and competency standards. It is worth getting at least two or three quotes and asking each installer about their experience with your specific wallbox brand if you have already chosen a unit. Some wallbox manufacturers also maintain their own approved installer lists, and certain energy suppliers offer bundled installation services. Whichever route you take, using an approved installer is non-negotiable if you want to access any grant funding or ensure the work is correctly certified. ### What happens during the survey visit? Before any work begins, most installers will carry out a survey, either in person or remotely via photos and a video call. The purpose is to confirm that your property is suitable and to plan the installation in detail. The installer will look at your consumer unit to check it has capacity for the additional load, identify the most practical cable route from the unit to your parking space, note whether your earthing arrangement is adequate, and flag any remedial work that might be needed before the wallbox can go in. The survey also gives you the chance to ask questions and agree the exact position of the unit. Most surveys are free and take under an hour. ### What is a DNO application and when is it needed? Your local electricity distribution network has limits on how much additional load can be connected to domestic properties. For most standard 7 kW wallbox installations, no application is needed because the additional draw falls within automatic approval thresholds. For higher-output units, certain older properties, or areas where the local network is already heavily loaded, your installer may need to apply to the DNO for permission before proceeding. This is handled entirely by the installer on your behalf, but it can add several weeks to the overall timeline. Your installer will know whether it applies to your property and will factor it into the schedule. ### What happens on installation day? Once any preliminary checks and applications are complete, the installation itself is usually done in a single visit. The installer will fix the wallbox to the wall at an agreed position, run the cable from the unit back to your consumer unit, make the electrical connections, and install any additional protection the installation requires, such as a dedicated circuit breaker. They will then test the unit to confirm it is operating correctly and walk you through the basic operation. If it is a smart wallbox, they may help you connect it to your home Wi-Fi and download the associated app. At the end of the visit you should receive an electrical installation certificate, which is an important document to keep safely. ### What if you rent or live in a leasehold flat? Renters and leaseholders face extra steps but are not excluded from home charging. If you rent, you will need your landlord's permission before any work can be carried out. Some OZEV grant schemes are specifically designed for renters, and some landlords are increasingly receptive because a wallbox can be a selling point when renting to EV drivers. For leaseholders in a flat, the situation is more complex because the parking space may be communal or the building may require consent from the freeholder or management company. In blocks of flats, a shared charging solution managed by the building may be more practical than individual wallboxes. It is worth raising the idea with your building manager or residents' association early in the process. ### How long does the whole process take from start to finish? For a straightforward installation with no DNO application needed, the process from initial enquiry to a working wallbox typically takes one to three weeks. Finding an installer, booking the survey, and scheduling the installation day accounts for most of that time. If a DNO application is required, add several weeks to that estimate. If remedial electrical work is needed at your consumer unit first, that is an additional step to schedule. Most experienced installers will give you a realistic end-to-end timeline at the survey stage. The actual installation day itself is rarely the bottleneck; it is the lead time for surveys and appointments that varies most. ### Frequently asked questions #### Do I need to tell my home insurer about a wallbox installation? It is advisable to inform your home insurer once the wallbox is installed, particularly if it is a permanent fixture on or within your property. Most insurers simply note it on your policy. An installation carried out by an OZEV-approved installer with a proper electrical certificate is unlikely to create any complications, but it is worth confirming with your provider. #### Can a wallbox be installed in a garage rather than outside? Yes, and in some cases a garage installation is preferable because the unit is protected from the weather. The installer will run the cable from your consumer unit to wherever you park, whether that is an external driveway, a carport, or a garage. The wallbox itself should be positioned so that the cable comfortably reaches the car's charging port without strain. #### Will the installation damage my driveway or walls? Cable runs may require drilling through walls or running conduit along surfaces, but a good installer will plan the route to minimise impact and keep the finish tidy. In most cases the visual impact is modest: a surface-mounted conduit along a garage wall or a short run through a cavity. Discuss the route and finish with your installer at the survey stage if this matters to you. #### What electrical certificate should I receive after installation? Your installer should provide an Electrical Installation Certificate (EIC) or a Minor Electrical Installation Works Certificate, depending on the scope of the work. Keep this document safely as you may need it when selling your home, making an insurance claim, or applying for certain grant schemes. If your installer does not provide one, ask for it before they leave. #### Can I get a grant towards the cost of installation? Grant eligibility depends on your circumstances: whether you own or rent, whether you live in a house or a flat, and whether you meet the current OZEV criteria. Schemes change over time, so check the current position on the GOV.UK website or ask your approved installer, who will be familiar with what is available and how to apply at the time of your installation. #### What happens if the wallbox develops a fault after installation? Most wallboxes come with a manufacturer's warranty, typically covering the unit for several years. Faults related to the installation work itself should be covered by your installer under their guarantee. For smart units, some faults are resolved remotely by the manufacturer's support team via the app or a firmware update. Keep your installation certificate and purchase documentation together so you have everything to hand if a warranty claim is needed.
