A few UK-listed investable options I'm aware of which might provide exposure to UK residential property and/or ownership of a buy(or build) to let business without the hassle of actually doing it yourself:
These two are basically REITs (real estate investment trusts) which own residential property and rent it out:
These two are the same sort of thing but are more focussed on "social housing":
And a new entrant aiming to house the homeless:
None of them have much history yet.
With a longer history there is "TM Home Investor" fund https://homeinvestor.fund/ (formerly "Hearthstone Residential"). It's relatively small (£60million) compared with the newer REITs listed above though, and the open-ended (fund) structure is probably best avoided for illiquid assets. The annual reports are well worth a read for understanding the economics of this sort of operation though.
Also of interest might be student housing specialists ESP, DIGS and UTG, or companies like PSDL which although listed on the London stock exchange, are actually investors in Berlin rental property.
From time to time over the years there have also been various savings accounts launched with their interest rate linked to house-price indices (most recently Castle Trust's "HOUSA" products), but I'm not aware of any currently available.
Before investing in anything like this, I can't stress highly enough the importance of doing your own research and understanding the business and its risks (and costs!).
