Primark plans to open four more stores across the UK over the next two years.
The new Primarks will be in Bury St Edmunds, Craigavon, Salisbury and Teesside Park.
Primark will hire 850 people to staff the new outlets.
The fashion chain is also swapping its shops in Bradford and High Wycombe to bigger premises.
The cheap clothing giant now has 190 UK shops, employing 30,000 people.
Primark chief executive Paul Marchant said: "The UK is our biggest market and as we continue to grow and expand our business internationally, we remain as committed as ever to investing on our stores to offer more customers our great value clothing, beauty homewares and more."
In November Primark launched a click and collect service in 25 stores across the country.
It means customers can browse products online, secure their favourites and select a preferred day and time to go and collect them in store.
Around 2,000 products are available to click and collect - including around 800 exclusive to the service.
Primark allows free returns if you need to take a product back.
At the moment, it will only include kids toys, clothing and nursery ranges across the North West of England, Yorkshire and North Wales.
Other ranges, including womenswear, menswear and homeware can only be bought in store for the time being.
Shoppers will also need to make a minimum purchase of £15 to use click and collect but there is no extra charge for the service.
Demand for Primark click and collect was so high the service crashed shortly after launching.

Primark first confirmed it would offer a click and collect service in an update back in June, shortly after it relaunched its UK website.
But shoppers still can’t order products for home delivery online - despite pleas for the fashion chain to add this as an option.
Primark lost more than £1billion in sales during the worst of the Covid-19 pandemic as shoppers could not order online.
