Industrial and product design

Professional indemnity insurance for product designers

If you design physical products for clients, you need professional indemnity insurance. A tolerance that stops parts assembling, a material that fails in use or a shape that infringes someone else’s design can scrap tooling, delay a launch or force a redesign, and the brand will look to its designer for the cost. PI usually covers that financial loss. If you also make or sell products under your own name, you need product liability insurance as well.

In short

Product designers carry the cost of mistakes that surface in tooling, testing or the market. In Great Britain the manufacturer, meaning whoever markets the product under its own name, is responsible for conformity assessment, technical documentation and the UKCA or CE marking, and Great Britain still recognises CE marking for many product types. Brands often pass design responsibility back to you through their contracts. General product safety in Great Britain still rests on the 2005 Regulations, while Northern Ireland has followed the EU General Product Safety Regulation since 13 December 2024. PI covers negligent design and unintentional IP infringement, subject to the policy terms; recall and product liability need separate cover.

Why product design needs PI, and where product liability takes over

Last reviewed 5 October 2026 by the Apex professional indemnity team.

Professional indemnity (PI) insurance usually covers your legal liability when a client loses money because of a negligent error in your professional service. For an industrial or product designer, that service is the concept, the CAD models and drawings, the material and component specification, design-for-manufacture advice and, often, help with testing and technical documentation.

Three policies are easily confused here:

A designer’s largest losses are often in the third category, where nothing has been damaged and nobody has been hurt, but a client has spent heavily on a design that does not work. This page covers physical products. If you design software, apps or digital services, see our page on PI for UX and digital product designers.

How claims arise for product designers

The following scenarios are illustrative. They show the type of allegation product designers face, not real claims or outcomes.

  1. A tolerance stack-up nobody checked. You design a two-part moulded housing. The tool is cut to your models, but the tolerances add up so that the parts will not clip together reliably. The tool has to be modified, the launch misses its retail window, and the client claims the tooling costs and lost margin.
  2. A children’s product that fails testing. A toy designed by you has a detachable part that fails the small parts test at the client’s test house. The product is redesigned and retooled, a retailer cancels its order, and the client says the hazard should have been designed out from the start.
  3. An enclosure that runs hot. Your enclosure for a mains-powered device leaves too little ventilation. Overheating appears in pre-compliance testing, and the client pays for a redesign, new tooling and repeat testing.
  4. A design too close to a competitor’s. A kitchen gadget you designed resembles a competitor’s registered design. The competitor threatens proceedings, the stock is withdrawn, and the client claims its losses from you on the basis that you should have checked.
  5. A material that degrades outdoors. You specify a plastic for garden furniture without checking its resistance to sunlight. Pieces crack within a season, warranty returns pile up, and the brand claims the cost of replacements and a reformulated range.
  6. A gap in the technical file. You prepare the risk assessment for a client’s technical documentation and miss a foreseeable misuse. A market surveillance authority asks questions, the client has to take corrective action, and it claims the cost from you.

In every case the question is whether your work met the standard of a competent product designer, which is the question PI is designed to defend.

The rules your designs are judged against

Most product regulation is aimed at manufacturers, not designers. It still shapes every claim against you, because your client will measure your design against what it needed to comply.

RuleWhat it saysWhy it matters to a designer
UKCA marking guidance (GOV.UK)A manufacturer is anyone who manufactures a product, or has it designed or manufactured and markets it in Great Britain under their own name or trademark. The manufacturer carries out conformity assessment, draws up technical documentation and a declaration of conformity, and keeps the documentation, typically for 10 years.If you design for a brand, the brand is the manufacturer. If you sell under your own name, you are.
CE recognition in Great Britain (GOV.UK)Under the Product Safety and Metrology (Amendment) Regulations 2024, Great Britain continues to recognise the CE marking for many product types, alongside or instead of UKCA.Clients will expect designs that support whichever route they choose, often both.
Designated standards (GOV.UK)Standards recognised by the UK government give a statutory presumption that a product meets the relevant essential requirements.Designing away from a designated standard leaves your client to prove compliance another way.
General Product Safety Regulations 2005, regulation 5 (Great Britain)No producer may place a product on the market unless it is a safe product.Applies to consumer products. The government consulted from 31 March to 23 June 2026 on a new framework, following the Product Regulation and Metrology Act 2025.
EU Regulation 2023/988 (Northern Ireland)Superseded the 2005 Regulations in Northern Ireland on 13 December 2024.Products sold in Northern Ireland follow different general safety rules from those in Great Britain.
Consumer Protection Act 1987, section 2The producer, anyone who holds themselves out as producer by putting their name or trade mark on the product, and the importer are liable for damage caused by a defect.This is product liability territory. Brands that pay out may then claim from the designer in contract or negligence.

Designer or manufacturer: where the compliance risk lands

The most important question for a product designer’s insurance is which side of the manufacturer line you sit on, and whether your contracts quietly move you across it.

Designing for a brand

When a client markets the product under its own name, it is the manufacturer and carries the regulatory duties. Expect its terms to push risk back to you: a warranty that the design complies with named standards or regulations, an indemnity for any non-compliance, and liability for the cost of recalls. A promise that a design will comply goes further than a promise to use reasonable care and skill, and PI policies often limit cover for that kind of guarantee. Negotiate it down to a reasonable care obligation where you can, and show your insurer anything you cannot change.

Selling under your own name

Designer-makers, crowdfunded launches and designers who license a range but keep their own branding can become the manufacturer, and under the Consumer Protection Act 1987 the producer or own-brander of a defective product is liable for the damage it causes. At that point you need product liability insurance, and possibly recall cover, alongside PI.

The technical file and the long tail

If you write risk assessments, test plans or parts of the technical documentation, errors in them are professional services errors. Manufacturers typically keep that documentation for 10 years after the last product is placed on the market, and a defective-product claim against a producer can be brought up to 10 years after it supplied the product. A designer’s exposure can therefore last as long as the product sells.

Who owns the design

Since 1 October 2014, the designer rather than the commissioning client is the first owner of UK design right in a commissioned design, unless the design is made in the course of employment. Brands usually require an assignment. Agree it in writing, and be clear about whether you warrant that the design does not infringe anyone else’s rights, because that warranty is where many IP claims against designers start.

What PI covers and what it doesn’t

Usually covered by PIOften excluded or limitedNeeds a different policy
Negligent design, CAD models, drawings and specificationsThe cost of recalling or withdrawing productsInjury or damage caused by products you make or sell (product liability)
Design-for-manufacture errors that waste tooling or delay launch, subject to the policy termsWarranties that a design will pass testing or comply, beyond reasonable care and skillRecall costs for products you place on the market (product recall cover)

Cover is subject to the insurer’s acceptance and the policy terms. Make sure the business description includes everything you do, especially if you prototype, source suppliers or manage production.

How much cover, and for how long

No regulator sets a PI minimum for product designers, so the limit comes from your clients and your largest realistic loss. Brands and manufacturers often state a PI limit in the design agreement, and some ask for product liability too. Base your limit on what a design failure would cost your biggest client: tooling, inventory, retesting and a missed season, not your design fee.

Frequently asked

Do product designers need professional indemnity insurance?

Yes, if you design physical products for clients. Design errors usually cause financial loss, such as wasted tooling, failed tests or delayed launches, rather than injury or damage. PI covers your liability for that loss, subject to the policy terms. If you also sell products under your own name, add product liability.

Is PI a legal requirement for product designers?

No law requires product designers to hold PI, and there is no regulator of the profession. In practice brands, manufacturers and agencies often require it in design agreements, sometimes with product liability too. The regulatory duties for UKCA and CE marking fall on the manufacturer, but contracts often pass design risk back to you.

Am I the manufacturer for UKCA purposes?

Only if the product is marketed in Great Britain under your name or trademark. GOV.UK guidance defines a manufacturer as someone who manufactures a product, or has it designed or manufactured and markets it under their own name. If a brand sells your design under its name, the brand is the manufacturer.

Does PI cover product recalls?

Usually not. Most PI policies exclude or limit the cost of recalling products. If a recall follows your design error, the brand may claim its wider losses from you, and PI may respond to that claim subject to the policy terms, but a brand or designer-maker needing recall cover should buy it separately.

Does PI cover me if my design infringes a patent?

Sometimes. Many PI policies cover unintentional infringement of design right, registered designs and copyright, but patent infringement is often excluded or sub-limited, especially in the US. Ask how your wording treats patents, and keep a record of the searches you ran before the design was finalised.

Who owns a product design when the client pays for it?

For UK design right in designs commissioned since 1 October 2014, the designer is the first owner unless the design is made in the course of employment, so a client that wants to own the design needs a written assignment. Put ownership, licences and any non-infringement warranty in the agreement.
