The UK now has over 700,000 domestic EV charge points, and the installation rate is accelerating. The Electric Vehicle Smart Charge Point Regulations 2021 set the technical baseline. But for the 3,000-plus OZEV-approved installers actually doing the work, the compliance documentation per installation is where the real overhead sits. Every domestic EV charger install generates a minimum of 4 documents, each submitted through a different system.
An EV charger installation is notifiable electrical work under Part P of the Building Regulations. As an installer registered with a Competent Person Scheme (NICEIC, NAPIT, ELECSA, or similar), you self-certify compliance and notify the local authority through your scheme provider. The Electrical Installation Certificate (EIC) must be completed to BS 7671, with a schedule of test results covering earth fault loop impedance, insulation resistance, RCD operation, and circuit protective conductor continuity.
For a straightforward domestic installation (dedicated circuit from the consumer unit to a wall-mounted charger), the EIC and test schedule takes 20 to 30 minutes to complete. For a more complex installation involving a new sub-board, PME earthing considerations, or load management, the documentation can take 45 minutes or more. The EIC must be issued to the customer and a copy retained by your business.
Every EV charger installation must be notified to the Distribution Network Operator. The reason is straightforward: a 7 kW charger running for 8 hours overnight draws significant power, and the DNO needs to know about it for network planning. Installations up to 3.68 kW per phase use the simplified G98 notification. Anything larger (which includes most 7 kW single-phase chargers) requires a G99 application.
The G98 form is a single page, but it must be submitted through the DNO's portal, which means creating an account, entering property details, and uploading the form. Each of the 6 DNOs has a different portal. A G99 application is more detailed and can take 30 to 45 minutes, plus weeks of waiting for the DNO's assessment. Rejections and requests for additional information are common, particularly in areas with constrained network capacity.
Since 2022, all domestic EV charger installations funded by government grants must be lodged on the TrustMark Data Warehouse. Even for privately funded installations, TrustMark lodgement is increasingly expected by mortgage lenders and warranty providers. The lodgement requires property details, installation details, the EIC reference, and customer satisfaction data.
The TrustMark portal is separate from your Competent Person Scheme portal, your DNO portal, and the OZEV portal. It takes 15 to 20 minutes per lodgement. The data overlaps substantially with what you have already entered elsewhere, but TrustMark has its own format and its own validation requirements.
The EV Chargepoint Grant (formerly EVHS) provides up to 350 towards the cost of installing a charger at a domestic property (for tenants and flat owners, with some landlord eligibility). The installer claims the grant through the OZEV portal after installation. The claim requires the customer's eligibility evidence, installation details, photographs, the EIC reference, and a signed customer declaration.
Processing a grant claim takes 20 to 30 minutes. Rejections for incorrect documentation are common, and each resubmission adds another round of administration. For an installer doing 300 grant-funded installations per year, OZEV claims alone represent 100 to 150 hours of annual admin work.
The Electric Vehicle Smart Charge Point Regulations 2021 require all new domestic charge points to be "smart" by default: capable of being remotely controlled, responding to time-of-use tariff signals, and pre-set to charge during off-peak hours. The installer must configure these settings at commissioning and provide the customer with documentation explaining how the smart functionality works, how to override it, and how data is handled.
This is not a separate submission to a portal, but it is a documentation requirement. The commissioning checklist (including smart settings configuration, Wi-Fi connection, app setup, and customer briefing) adds 15 to 20 minutes per installation.
CRM tools like Tradify, Simpro, and Joblogic handle quoting, scheduling, and invoicing. Manufacturer apps handle charger configuration. But nothing integrates the compliance chain: Part P notification, DNO application, TrustMark lodgement, OZEV grant claim, and smart charge point commissioning documentation. Installers re-enter the same property and installation data into 4 or 5 different systems, with no automated status tracking and no single view of which installations are fully compliant.
For a business doing 200 to 400 installations per year, the compliance documentation overhead is equivalent to a part-time admin role. That is a cost most installers did not budget for when they entered the EV charging market.
