The professional survey checks whether the existing supply and installation can support the proposed additional load.

What a professional home chargepoint site survey should cover
A competent installer should assess the property, proposed charging load and existing electrical installation before fixed chargepoint work is agreed. You can prepare parking, access, usage, equipment, permission and existing-document information without opening electrical equipment. Ask for a written outcome that identifies assumptions, required professional work, the DNO route and any unresolved stop condition.

Key facts and evidence
As of 13 August 2026, a UK home chargepoint site survey should end in a written professional outcome covering supply capacity, maximum demand, existing equipment, proposed route, load management, remedial work, DNO involvement and permissions. The householder may provide documents and charging needs, but may not open, probe, alter or test fixed electrical equipment.
Sourced fact
The owner may provide usage, parking, access, permissions and existing records without inspecting inside electrical equipment.
Sourced fact
The survey outcome should state assumptions, constraints, required work, DNO handling and unresolved decisions in writing.
Sourced fact
Supply assessment, maximum-demand judgement, fixed-electrical inspection and every measurement are Red and ProfessionalOnly.
Prepare non-technical information for a UK chargepoint survey and ask for a written professional outcome before installation.
Information to prepare
Provide the property type, parking right, preferred charger position, ordinary vehicle-use and charging needs, route preferences, access constraints, other substantial electrical loads or generation, permissions, previous electrical certificates and any DNO correspondence already held. Preparation is documentary and non-contact.
What the written outcome should resolve
Ask the installer to state whether the existing supply and installation are adequate, whether load management, remedial work or a supply change is proposed, which DNO route applies, what permissions and civils remain, and which assumptions could change the price. The professional owns every technical conclusion.
When the survey needs revisiting
Return the proposal to the installer when the charger model, position, route, parking arrangement, property permission, other major load or supply information changes. A quotation based on old site assumptions should not be treated as a current design decision.
What to do next
Use this page to prepare information and evaluate the written survey outcome, not to assess electrical capacity yourself.
Immediate action: Book a site survey with a registered competent EV chargepoint installer before accepting a fixed installation scope.
- Pause the project if supply or earthing information is unknown, existing equipment is damaged or a required DNO decision is outstanding.
- Pause if the quote is based on a remote assumption that conflicts with the actual site.
Do not infer from missing evidence
- Keep all fixed electrical enclosures closed and provide only documents, photographs already available and ordinary site information.
- Withhold installation approval until the competent installer records a complete site-specific outcome.
Professional hand-off
- A registered competent EV chargepoint installer or electrical designer should complete the survey and involve the DNO where required.
