I think a lot depends on what the OP's aim is - to try and clone Fuller's ESB, to create a typical British strong bitter, to make a USian ESB style beer (which doesn't exist in the UK) or just to make a beer they enjoy.
The answer to the question depends on which of those is the aim. But just as far as the Fuller's beer goes, then yes you should have a
read of the thread in which I've posted actual Fuller's brewing logs. Current ESB is 35 IBU and 5.5% ABV in cask, 5.9% in bottle.
So if you are using a yeast with 72% attenuation, then you want an OG of about 1.060.
If your brewhouse efficiency is 75%, then an OG of 1.060 will need about 11lb of base malt.
The amount of hop additions will depend on the alpha acid content of your hops, but 2018 Goldings cones can be as high as 6.2% in which case you get 35 IBU with :
1oz 60 minutes
1oz 15 minutes
1oz 5 minutes
and you could throw some in as a dry hop if you want to be tidy with a 100g or 4 oz packet.
Naked oats are a crystal malt. Combined with the 80L and Special B that puts the recipe @ 30% crystal malt. I think that's WAY too much. The benchmark for an ESB is Fuller's and I'll go as far as 12-15% crystals in my versions but with 30% they are going to take over the beer IMO.
USians generally put waaaay too much crystal in their British recipes - that January 2018 recipe for Fuller's uses 7.2% light crystal, and for me the Fuller's beers have about as much crystal as I care for. You will find a few breweries using more, but not many - the Yorkshire breweries will be using more like 2-3% crystal. Don't forget that British pale malts are cooked a little more than elsewhere, so you're getting more contribution from the base malt.
You might consider some type of sugar for your character instead of the additional crystal. The English routinely add sugars to their beers.
That's not so much the case as it used to be in the century after the Free Mash Tun Act of 1880. If you look at what respected breweries like Fulller's and Tim Taylor are doing, they used a bit of sugar 40 years ago but no longer do so for their main beers, CAMRA has put quite a lot of pressure on them to remove adjuncts regardless of their widespread use in the 20th century.
