You can use the above website to get an idea where your household "fits" in terms of income vs average household in the UK. Essentially it takes:
Net earnings (wage or salary income, benefits you receive, income from savings and investment, profits or losses from self-employment, and any other sources of income) less your council tax & gives you an answer.
I put our details in and it has our household in the top 6% yet OH and I both earn well under 6 figures and, after pension contributions, we are entitled to claim child benefit. If we didn't have the kids then even without the benefit we'd be top 3% of households.
I think we are reasonably well off but surely there are enough people who are independently wealthy &/or have 6/7 figure salaries that no one with normal jobs/wages fits in the top 5%? If it's accurate then just how concentrated does that make wealth in the top 1% or less?
