Do I get a Tesla one or universal one?
Tesla not eligible for OLEV grant, but OLEV installations are only by approved fitters and they often seem to work out "more expensive", to cover the red tape etc. so can be worth looking at a non-OLEV charger and your local Sparky fitting it. Non-OLEV likely to be more expensive, overall, but you might decide you prefer something - aesthetics perhaps?
The Tesla Wall charger has a button you can push to stop the charge and release the cable. The alternative is digging your phone out and pressing the APP button, or reaching into the car to stop it on the dash. For some people this has been important to the decision.
Tesla Wall Charger supports 3-Phase (if you happen to have that at your house) and load-balancing if you have multiple charger / EVs
Plenty of OLEV-approved chargers also have those abilities.
How much will home installation cost?
On top of the OLEV grant generally £300-£500 - if your distribution panel is at the front of your house within spitting distance of where you park your car ... but if your distribution box is round the back, or you have to dig up your drive
, then all the hassle of fitting a cable and making good the decorations. OLEV fitters seem to be looking for "easy jobs" so if your install is difficult you might be better off with your local friendly sparky and a non-OLEV charger. Local sparky is likely to be far more happy for you to "pull the cable" yourself, to save cost (if your installation has a long cable run / outdoor trench etc)
You can get a quote for each and compare of course
Realistically how much difference is it in £ per mile based on a diesel car at roughly 35mpg to a M3
A Model-3 will do 4 miles per kWh (a "unit" of Electricity) on a good day, and 3 miles on a not-so-good-day. For short journeys, in winter, it will be less efficient - but your 35MPG car isn't going to manage that on a cold, winter, short journey either
Assuming you have home charging, and will charge the car overnight most of the time, then Off Peak rates (e.g. Octopus Go) can be around 5p a unit ... so, best case, 4 miles for 5p
In reality there are some losses, but reasonably safe to assume 2p - 3p a mile
Diesel £1.30 per Litre, 35 MPG = 16.8p per mile
Also to consider:
Reduced servicing costs
Brakes will last 100,000-150,000 miles
Do you have free parking for EVs? London Congestion charge = £10 p.a.
But Luxury Car Tax in Yr2+
I am still debating whether to go for the Standard + or the Long Range
Have a look at
A Better Route Planner and try all your longer journeys. You can choose Model - SR or LR - and whether the weather is a "nice Summer's day" or "foul"
and it will tell you where you would have to stop, and for how long.
The LR is a significant additional chunk-of-change ... and looks expensive for "pure range", but for me the time it saves is worthwhile
Travel further before having to charge
Thus some journeys need no charging stop
Charge less - you only need to charge just-enough to get to destination, you don't "fill the tank" like Petrol, so LR needs less top-up than SR to get to destination
Charge into "taper" less often - Supercharging slows down dramatically above 80%, so best to Supercharge 10%-80% and that is more miles in LR than SR
LR charges faster than SR - (higher kW rate) so more miles-per-minute
You should be able to simulate all those benefits with ABRP
