The uncertain economic environment hasn’t discouraged me from continuing to buy UK shares in 2020. And I plan to keep building my Stocks and Shares ISA next year too. The broader outlook is fraught with problems — Covid-19 and otherwise — but there are still many companies that should deliver terrific shareholder profits in the short term and beyond.

Here’s a cluster of top-quality UK shares I’d be happy to buy for my own ISA in 2021:

#1: Package powerhouses

Getting a slice of the e-commerce segment is, in my opinion, a must-do for every UK share investor worth their salt. I’ve bought logistics and warehousing specialists Tritax Big Box and Clipper Logistics in 2020 to boost my own exposure. But there are other ways to do it too. Online fashion retailers ASOS or Boohoo are prime examples. Investors can also buy stocks such as address verification provider GB Group or online marketing assistant dotDigital as well. The list is vast.

One other e-commerce play on my radar today is Royal Mail. Couriers like this are getting rich as parcel traffic increases, and this particular operator has seen UK revenues leap by £380m year-on-year during April-November as a result. And the UK share is investing heavily in technology to capitalise on the online shopping boom to its max in the years ahead.

#2: A top-class UK tech share

The digital revolution creates stunning profits opportunities for many UK shares over the next decade. One of these on my radar is Kape Technologies, one of London’s leading cyber security companies.

2020 has witnessed a sharp spike in cyber attacks and online fraud. Yet many companies remain ill-equipped to battle this soaring problem. That gives the likes of Kape ample sales opportunities. According to Bain & Company, just 43% of executives believe their firms follow best practices for cybersecurity. The consultancy reckons the problem is even worse than this however. It says that “only about 24% of firms actually meet that bar.”

#3: Another fortune-builder

I already own Ibstock in my Stocks and Shares ISA. But I’m thinking of increasing my holdings in 2021, given the bright outlook for housebuilding in this country. The government needs to create 300,000 new homes a year by the middle of the decade to meet the Britain’s housing requirements. And this UK share, with its wide network of brick manufacturing plants and catalogue of over 450-plus product types, is well-placed to capitalise on this phenomenon.

Things haven’t been easy for Ibstock this year as Covid-19-related construction site shutdowns has hit brick demands. But volumes are back in recovery and margins are rising at a ripping rate as well, giving it strong momentum moving into 2021. This is a UK share I plan to hold for the next 10 years and possibly beyond.
