An installer quotes from a photograph of a driveway. He arrives to find a consumer unit from the nineteen eighties with no spare capacity, an earthing arrangement that needs attention and a supply already close to its limit with an electric shower and a hob.
The charger costs what it costs. Everything else about the job has just changed.
Where the money actually goes
Not the unit. The board, the protective devices, the earthing arrangement, the cable run and whatever has to happen to make the property capable of supporting the charge.
Why headline pricing causes the problem
Advertised installation prices assume a modern board with spare capacity, a short run and an ideal supply. A large share of houses do not match that, and the customer only finds out on the day.
Ask for the board photograph first
The consumer unit, its label and the surrounding area. One photograph answers more pricing questions than an entire phone conversation.
Ask about the age of the installation
When the property was rewired, whether the board has been changed and whether there is any certification. It indicates what the installer will find.
Ask about spare capacity
Whether there are free ways in the board. A full board means either a change or an additional arrangement, and both cost money.
Ask about the main fuse and supply
What the supply rating is and what else in the property draws heavily. It determines whether load management is required and whether a supply upgrade is even a conversation.
Explain load management plainly
That it allows charging within the available supply rather than requiring an upgrade, what it costs and what it means in practice for charging speed. Customers prefer it once they understand it.
Explain the earthing arrangement
Without jargon. That the installation must be safe for outdoor charging, that some properties need additional provision and what that involves. Customers accept cost they understand.
Publish the common additions with prices
Board change, additional protective device, longer runs, trenching, load management and making good. It turns a surprise into a published option.
Quote in two parts
The charger and standard installation, then the property specific work identified at survey. It is honest, it is comparable and it prevents the doorstep conversation.
Explain when a supply upgrade is needed
Rarely, and what it involves, who arranges it and the likely timescale. Customers should know it exists as a possibility rather than discover it.
Be honest when a property is difficult
Flats, shared supplies and properties without off street parking need a different conversation rather than an optimistic quote, which is the ground in home EV charger installation enquiries and survey details.
Cover the funding question
Where schemes exist, what they cover and who qualifies, as in grant and funding questions in EV charger enquiries.
Use it as a route into wider work
A board that needs replacing is a job in itself, and the customer already trusts you, which connects to rewire and consumer unit quote requests.
Capture it before anybody drives anywhere
Photographs, distances and the supply details, collected at any hour, which is the approach in an AI chatbot for electricians.
