I am looking for a target-maturity bond ETF for UK Gilts but I couldn't find any by using an internet search engine. I would like something similar to iShares iBonds Dec 2033 Term Treasury ETF but for UK Gilts instead of US treasury bonds. Does such an ETF exist? If not, what are the practical alternatives for getting UK government bond exposure that have the following characteristics:

• Easy for foreigners to purchase
• Easy to liquidate
• Has a fixed maturity date
• Has a low minimum investment requirement (e.g. less than 1000 GBP).
