Looking at the headline figures, it's easy to think the story of UK equity fund holdings in growth portfolios is one of BlackRock's dominance through the wide number of iShares funds it offers
But looking a bit deeper and it shows a more complex story.
It is certainly the case that BlackRock - largely due to its iShares range - is the most popular fund manager in the UK equities segment of our growth database.
For example iShares Core FTSE 100 ETF is held seven times while iShares 100 UK Equity Index, iShares UK Equity Index and iShares FTSE 250 ETF are all held once or twice.
But when you strip out growth funds and focus on income, then allocators prefer funds run by smaller fund houses such as Evenlode and Artemis.
Of course Evenlode does well here simply due to the sheer popularity of Evenlode Income, which is the single most popular UK equity income fund in our database.
In fact to drive this point home further, nearly half of the UK equity funds in our database are run by companies with total assets under management of £50bn or less.
These include companies such as Evenlode, but also Montanaro, Chelverton, Artemis and Gresham House.
One factor at play here will be the fact only one passive UK equity income fund is held in our database, and it is held only twice: Vanguard FTSE UK Equity Income Index. There also isn't a single passive UK smaller companies fund held in our database (unlike with US equities where there are several).
This means the active/passive split for UK equities is firmly to the advantage of active funds.
As far as style goes there are few surprises here. The UK is a value market and this is obviously reflected. Even among smaller companies, which might be expected to have a growth tilt, value style funds dominate (as measured by the Morningstar style box).
So how successful are allocators at picking UK equity funds in terms of pure performance? Well, quite.
Comfortably most UK equity fund picks - including active and passive funds - outperform their sector and just shy of half of the UK equity funds in our database are in the top quartile.
But despite this, some allocators are using funds which are towards the top end of the cost range.
About 60 per cent of the UK equity funds in our database have an OCF in the 0.6-0.9 per cent range - an area where the regulator has seen clustering for some years now.
But about 16 per cent of UK equity funds have an OCF between 0.9 and 1.2 per cent, with several above 1 per cent - Trojan Income and Sandford DeLand Buffettology among them.
Of course these are the OCFs published on FE Analytics and it is likely allocators will have reached their own deals with fund managers.
