Kwik Save是导致Aldi扩张问题的主要竞争对手之一。然而，在更多的当前时代，Aldi的主要竞争对手将被讨论。竞争的形式有特易购、阿斯达·塞恩斯伯里、莫里森和利德尔。在这些竞争对手中，Aldi和Lidl是主要的折扣店。考虑到Aldi和Lidl确实能提供物有所值、物有所值的商品，因此它们理应占据良好的市场份额，但英国消费者认为，他们在哪里购物是他们在社会中地位的社会指标(Smith & Sparks, 1993)。因此，非折扣超市的市场份额仍然很高。乐购占据了28.2%的市场份额，是最高的。Asda、Sainsbury和Morrisons的市场份额分别为16.7%、16.2%和10.7%。Aldi和Lidl的份额相对较小，分别为5.6%和4.2% (Shadbolt, 2015)。
Aldi的主要竞争对手是Lidl。Lidl也是一家德国折扣店，截至2015年，它被评为全球第四大零售商。它的销售额约为1280亿美元。阿尔迪保持“年度杂货商”的称号已经有一段时间了。Lidl于2014年被授予该称号。Lidl提供了与Aldi相同的优势(Thals, 2015)。它允许员工人数最少，将有深冰柜，客户可以自己访问。除了Aldi提供的优势之外，Lidl还提供了更多的优势。它提供优质品牌、高端葡萄酒、基于地点的服务，以及更多可以使Aldi对英国市场的影响翻番的服务(Thals, 2015)。虽然Lidl现在在市场份额上落后于Aldi，但差距很小，Lidl可以赶上来。其他四个竞争对手Tesco、Asda、Morrisons和Sainsbury目前也在进行战略发展(Shadbolt, 2015)。
Kwik Save was one of the main competitors that led to issues in expansion for Aldi. However, in more current times Main competitors for Aldi will be discussed. competition in the form of Tesco, Asda Sainsbury, Morrison, and Lidl. Of these competitors Aldi and Lidl are the main discount style stores available for the consumers. While Aldi and Lidl hence should logically command a good market share given that they do supply value and quality for money, UK shoppers believe where they shop is a social indicator of where they stand in society (Smith & Sparks, 1993). Hence, the market share for the non-discount supermarkets are still high. Tesco commands a market share of 28.2 percent and is the highest. Asda, Sainsbury and Morrisons command a market share of 16.7 percent, 16.2 percent and 10.7 percent respectively. Aldi and Lidl on a comparative note share a much smaller percentage in the amount of 5.6 percent and 4.2 percent respectively (Shadbolt, 2015).
Aldi’s main competitor is Lidl. Lidl is also a German discount store and as of 2015 was ranked as being the fourth largest retailer in the world. It has around 128$ billion in sales. Aldi had retained the title of ‘Grocer of the year’ for some time now. Lidl was given the title in 2014. Lidl provides the same advantages as Aldi (Thals, 2015). It allows staffing to be minimal, there will be deep freezers which the customers can access themselves. In addition to the advantages that Aldi provides, Lidl also adds more. It offers premium brands, high end wines, locations based services and more that could double the Aldi effect on the UK market (Thals, 2015). Although Lidl is now behind Aldi when it comes to market share, the difference is minimal and Lidl could catch up. The other four competitors Tesco, Asda, Morrisons and Sainsbury are also developing strategically at present (Shadbolt, 2015).
