That's a meaningless phrase.
It's called having a good reputation among your peers, the sectors you do business in, or the communities you serve.
But if your whole life is spent on the dole or you can only manage to work zero-hour contracts then of course being good at what you do and garnering a reputation for it would be something utterly meaningless.
So everyone who is hardworking and enterprising is a "household name"? That's hilarious!!!!
You're wrong. People who are very good at what they do and take pride in their work really do want to be a household name. This is so whether they are someone like Bill Gates (entrepreneur and now billionaire philanthropist) or a Polish plumber working in East London who gets loads of referrals due to his expertise and dependability.
So a shopkeeper, a financial analyst, a language school owner, a publican, a builder, a computer operator, an old-age pensioner or a farmer should have "published studies" or "technological patents".
Many do. Regarding shopkeepers the big, brandname stores of today were founded by people who started out at the bottom in shops working for others and either made it to the top or earned success by breaking out on their own. Financial analysts are always publishing studies. It's also commonplace today for people working with computers (design, programming and operation) and even farmers to contribute to trade journals and/or develop new patents in their respective career fields.
The only exception to this would be some British scallywag who lost work as a builder to more highly skilled immigrants from the Continent; who then failed at running a pub in Blighty; then fled to Poland hoping but failing to start a language school; and now as a bitter washed-up OAP just surviving off benefits spends all day on PF railing against Poles and Polonia.
And doesn't detract from the confirmed fact that only 0.0002% Brits claim unemployment benefits from PL - the rest are by and large highly productive and have a larger than average income (with correspondingly higher tax/ZUS) - basically an elite section of society who contribute far, far more than they take.
So name them.
