MI Supplies Active Deals, Sales & Codes in June, 2026

MI Supplies is a UK-based retailer specialising in workwear, safety clothing, footwear, and PPE. Founded in 2005 by Managing Director Alex Ingham — the name blends M for Murray, his wife’s maiden name, and I for his own surname — the business has grown from a single operation to multiple warehouses serving domestic and international customers. They stock leading brands including Timberland, Caterpillar, Mascot Workwear, Portwest, Snickers, and Helly Hansen, alongside what they describe as the UK’s largest Carhartt collection.

Beyond retail, MI Supplies provides a full printing and embroidery service for company branding. There’s no set-up fee and no minimum order — even a single branded jacket is viable — and a free logo swatch proof is sent before production so you can approve the design. For businesses managing larger teams, a dedicated B2B ordering portal offers bespoke product selection, expenditure tracking, and targeted cost reductions that simplify uniform procurement across the board.

The MI Rewards loyalty programme lets customers earn points across thousands of products, with periodic double and triple points events. Other built-in perks include Klarna buy now pay later, 365-day returns, and free delivery on orders over £115. New arrivals start from as little as £4, and signing up to the newsletter unlocks access to exclusive promotions.

Combine these benefits with the discount codes we’ve gathered on this page — whether it’s £5 off a first order or 5% off selected items — and the savings stack up quickly for both individuals and businesses.

When’s the best time to shop at MI Supplies?

MI Supplies runs promotions year-round, but the deepest discounts tend to land around Black Friday and the January sales. Newsletter subscribers often get early access to these events. New product lines start from as little as £4, so checking the New Arrivals section regularly can surface fresh deals before popular sizes disappear. We’d also keep an eye on this page — our codes are updated as new ones become available.

How do I maximise savings on a workwear order?

Sign up for MI Rewards first — you earn loyalty points on every purchase, redeemable on future orders. Layer a discount code on top; FIRST5 takes £5 off a first order. Push your basket above £115 to unlock free delivery. If the total’s steep, Klarna spreads it interest-free. Four saving mechanisms working together on a single order.

Is the embroidery service worth it for a small team?

Absolutely. There’s no set-up fee and no minimum order, so even a single branded jacket is viable — that’s unusual in the workwear sector. The free logo swatch proof means you approve the design before production starts, which eliminates the risk of a wasted order. For small businesses that can’t commit to bulk runs, this flexibility is a genuine differentiator.

How generous is the returns policy compared to other workwear retailers?

At 365 days, it’s among the most generous in the sector. Most workwear retailers cap returns at 28 or 60 days. This extended window is particularly useful for businesses ordering in bulk — if a batch of safety boots doesn’t fit your team, you have nearly a year to sort it out rather than scrambling within a fortnight.

Should I use Klarna or pay upfront?

Klarna suits larger orders where cash flow matters — kitting out a new hire before a client invoice lands, for instance. For straightforward personal purchases, paying upfront keeps things simple and ensures MI Rewards points post to your account without delay. Either way, your discount code works the same.
