My advice to you is to look at buying some German catering equipment. Having worked in catering for years, the difference in quality between Germany-made products and UK-made products is night and day. Sure, you pay a bit more for the German stuff, but the quality is beyond reproach. You can find some great stuff online, too, so you do not even have to stick to shopping locally.
One company that I really like for the job is https://www.rjenterprises.co/ – they sell some great stuff and tend to be a good choice for anyone looking to spend a little more to get guaranteed quality. The range of products on offer is great, as is the overall value for money. Add in the speed of delivery and the customer support, and this is a no-brainer for my company.
