Tesla wall charger or not

I may have mentioned this before but most houses have 20 amp wiring with wither a 15 or 20a breaker. Changing the outlet (industrial, not commercial or residential please) and need breaker if it’s it 20A and you have a notable but not massive upgrade. You could also pull a 30A /120 not 240 but much more complex and expensive.
You can also run your own conduit and wire and let the electrician seal with the outlet and breaker panel.

I paid $950 to have a WC installed in my garage. Eletrician had to run wires from the outside panel through the attic and then down to the garage. With the current tax incentives, you can get 30% back (up to $1000) from the goverment for installation and charger costs, so I think it's a good deal.

The EV Charger Tax Credit Gets A 10-Year Extension—And A Few Upgrades
A recently expired federal tax break for electric vehicle (EV) chargers got new life under the recently passed Inflation Reduction Act—a move that will give taxpayers up to $1,000 in a tax credit. The section 30C tax credit–officially referred to as the Alternative Fuel Vehicle Refueling Property

First off, "Welcome." Your identification information says "South Yorkshire." Maybe there is a North American community by that name, or maybe you are moving to NA? But if you do reside in Great Britain, due to the differences in the electrical grid and home charging equipment I would also encourage you to ask questions of knowledgeable TMC folks in your neck of the woods, for example here. Meanwhile, the North American-centered responses here may still be generally applicable.
At the risk of tooting my own horn, might I also suggest this decision-making guide. It is North American-focused, but it may still assist you (if you will substitute in the UK-specific equivalent Tesla equipment).
You asked for a comparison of Tesla and third-party equipment. I'll leave that up to the YouTube gentleman @DeltaOne mentioned. My general understanding is that the better third-party wall and mobile connectors can match Tesla's equipment in quality, may have additional features, and can sometimes be more expensive than Tesla connectors. Nonetheless, I personally like the idea of using Tesla equipment to charge Tesla cars. Besides assurance of full compatibility, one benefit is that the Tesla connector comes with the proper Tesla proprietary car-plug. No adapters are necessary. (This is not now a concern in the UK, I believe.) In North America most aftermarket 240v AC wall connector cables will come with a J1772 plug, so a J1772 adapter (that still comes with new cars, I believe) will be necessary to charge a Tesla.
You mentined wanting to charge between 00:30 and 04:30 hours. Did you mean between 12:30am and 4:30am at night, or did you mean you only want to charge from 30 minutes to 4 1/2 hours at a time? If it is the former, you can program your car to charge at certain set times. (For example, I plug in at home but my car knows to only start charging after Midnight.
If the the latter, I will ask--are you sure you can't afford to just let the car charge overnight (when most of us are asleep). Full charging at home with AC current (in North America) takes a number of hours. However, if you return home with a good amount of energy remaining in the batteries, you will probably have no problem topping off in 4 1/2 hours or less every night if you use a 240-volt circuit with adequate power (say 40- or 32-amps). Sounds like a 50-amp circuit would be good to install in your home. (There are several factors to consider.)
Yes! That is Tom Moloughney, now of YouTube's "State of Charge" Channel and associated with InsideEVs also, I believe. I happened to mention him here with regard to CCS1 adapters.
I have enjoyed some of his detailed online reviews. Talk about a self-made man. He seems to have done very well over the years as a YouTube personality. Never has to buy charging equipment ever again, I imagine.
Agreed. I commented on this very issue when I recently added a new analysis (see "Chart 3") in my Decision-Making post. My cost numbers may be crude, but are probably good enough to suggest that the traditional argument--that installing a 240v wall outlet is always the cheaper alternative--may not hold water anymore.
Granted, there are reasons to use a good (but not a cheap) 240v wall outlet. I have always been partial to the Hubbell NEMA 14-50 receptacle + Tesla Corded Mobile Connector combination, especially now that this Tesla connector has been reduced in price to $200 (US). Trouble is, you never seem to be able to get them from Tesla. (Why reduce the price only to let Corded Mobile Connectors be chronically "Out of Stock?")
Regardless, I fully acknowledge that overall the Tesla wall connector is arguably the better choice. And experience tells me that most folks can do very well charging (overnight) at 32 amps or less (even for Models S and X). That means that spending money on 60-amp or greater house circuitry is unnecessary for most households. So the wall connector--which can be "turned down" to, say, 32 amps and requires no expensive GFI circuit breaker in some/most areas--becomes an even greater cost-effective option.
Final comment: My sense is that the most important single factor to home charging is proper installation. When we do hear about problems, It seems like a majority can be traced to faulty or sloppy installation (by both DIY-ers and, sadly, pros). Take the time (as you are already doing) to learn from experienced folks, buy quality equipment, and be sure that all components of your home charging assembly (breaker panel, circuit breaker, house wiring, wall outlet or connector, and charging cable) are proper (meet code requirements) and installed correctly.
