Best welding jacket UK

Updated: 16 October 2026

You want one welding jacket to open on amazon.co.uk, and a reason to leave it. The trouble is that 4.6 stars sit on two stories. The Portwest BIZ2 prints EN ISO 11611 Class 1. The YESWELDER leather coat, at £61.74, has the same 4.6 and prints no class. The Products Compared editorial team compared the nine listings in the [welding jacket comparison](/hub/occupational-safety/welding-jacket) on 15 October 2026. There was no lab test, and Amazon links are affiliate links. The best welding jacket UK shoppers can defend from this basket is conditional: the black Portwest BIZ2 in the size that fits, when you need a class on the listing and the work is still Class 1 territory.

Best for a printed Class 1 jacket

Open the Portwest BIZ2 when the listing has to show a welding class. The amazon bullets say 100 percent cotton at 330 g/m², 780 g, concealed studs, and EN ISO 11611 Class 1 (A1+A2). A1 and A2 are flame tests, so the welding class stays at Class 1. That style is the top pick for lighter MIG, TIG, or bench work, because it is the only one that prints the standard. Take the black XL at £28.98 if XL fits. Take the black XXL at £22.68 if XXL fits. They share 4.6 from 1,129 reviews, and buyers mention other sizes, so the count is not one size only. The XXL row is the best value when that size fits. Earlier checks are in the welding jacket buying guide.

Skip it when the sleeves already hole

Skip the Bizweld when sparks already go through light cotton, when you weld overhead or under a car, or when the risk assessment asks for Class 2. The shared UK reviews describe both outcomes and support no percentage. Several people report holes and burns through the sleeves. One comment says hot sparks can go through even when the cloth does not catch fire. Others describe light fabrication, including a week without a burn. If your last cotton sleeve has a pinhole after a normal afternoon, 330 g/m² Class 1 cloth has already shown its limit on your job. Once the sleeves hole, the nine rows only offer unlabelled leather or an unlabelled hybrid.

Why the 4.6 leather coat is not the pick

The YESWELDER at £61.74 is also 4.6, from 994 reviews. UK reviews include under-car welding where metal stayed in the jacket, and a working welder who says leather stops heavy spatter for them. Weight, heat, and a new-leather smell repeat. The page still does not print EN ISO 11611. A star line is not a certificate. The Portwest arc figures, ELIM 8.3 cal/cm² and ATPV 11.2 cal/cm², stay on the Portwest. They are not a welding class. The QeeLink leather coat at £56.99 has 4.5 from 649 reviews and no class. A long review count does not make it the best value beside labelled cotton at £22.68.

If you need the words Class 2

If you need the words Class 2, none of these nine listings can say them. Leather here does not become Class 2 by price or by a 4.6 rating. EPT Workwear lists a Portwest SW34 leather jacket as EN ISO 11611 Class 2 (A1). That jacket is not an ASIN in this comparison. For light work and a printed class, the top pick remains the BIZ2 in the size that fits, and the XXL row is the best value when XXL fits. For heavier spatter, leave the Bizweld and look for a page that prints Class 2, or accept that the leather here is unlabelled.

Common questions

Which jacket should I open first?
Open the Portwest BIZ2 if you need EN ISO 11611 on the listing. The black XL is £28.98 and the black XXL is £22.68. Both print Class 1 (A1+A2) on 330 g/m² cotton, and they share 4.6 from 1,129 reviews. Choose the size that fits. The XXL is the best value when XXL fits. It is the same style, not a higher class.
Is the cheaper Portwest XXL the same jacket as the XL?
Yes. Both are the black Bizweld BIZ2, Class 1, with the same fabric weight and the same shared review text. The XXL is £22.68 and the XL is £28.98. The XL care line says machine wash cold, lay flat, and use a medium iron. The XXL line only says machine wash. Follow the label in the garment.
Why not the YESWELDER, which also has 4.6 stars?
The YESWELDER at £61.74 is 4.6 from 994 reviews, and UK comments include heavy spatter and under-car work. The listing does not print EN ISO 11611, a thickness, or a weight. Stars can match the Portwest while the label does not. If you need a class you can quote, the leather coat loses that test. If cotton sleeves have already burned through, it becomes a candidate, still without a class.
When should I skip the Bizweld?
Skip it when your sleeves already hole, when you weld overhead or under a car, or when the risk assessment asks for Class 2. UK reviews of this shared pool include burns through the sleeves and light use with no burn. There is no rate. A week of light fabrication in one review is not a forecast for flux-cored wire or gouging. Class 1 is the lower level by design.
Is there a labelled Class 2 leather jacket at all?
Yes, outside this basket. EPT Workwear states EN ISO 11611 Class 2 (A1) on a Portwest SW34 leather jacket. That page is not one of these ASINs. Inside the nine, every QeeLink, LeaSeek, and YESWELDER jacket omits the class. Class 2 gets written down when a seller has stated it.
Does best mean best for TIG, or best for overhead MIG?
It means best here for a printed Class 1 jacket. That lines up with TIG, gas welding, and low-current MIG, with the burn-through reviews kept in view. It does not mean best for overhead MIG, flux-cored wire, or cutting. Those jobs are where the public guides move towards Class 2, and no row here prints Class 2. A single winner with no process attached would hide that split.
