Succession Planning for Family-Owned Manufacturers

In my work with manufacturers, the question of who takes over next tends to sit in the background for years.

New research from Make UK and Bishop Fleming suggests that is changing fast, with inheritance tax as the trigger. Succession planning for a family manufacturing business needs to be seen as a board-level priority, and most of the work that matters sits with the owner rather than the accountant.

That’s why I want to dig into what that work involves and how it connects to your wider strategy and business growth plans.

Executive Summary:

Most family-owned manufacturers are worried about how inheritance tax changes will affect handing on the business.
Full Business Property Relief now covers only the first £2.5 million of qualifying assets.
Tax is the trigger, but choosing and developing a successor is the harder work.
Separating family roles from business roles protects both the family and the company.
An independent non-executive director gives the transition structure and credibility.

Succession Is A Leadership Project, So You Need The Right Support.

The tax advice matters, but the plan that keeps the business strong is built by the owner and the board. Find out how non-executive support can help, or get in touch to talk it through.

Why Family Manufacturers Are Worried About Succession

Family firms carry a large share of UK manufacturing. The Who Inherits UK Manufacturing? report finds that family-owned firms make up 65% of manufacturing businesses, add an estimated £94bn to the economy and support around one million jobs. It also found that 78% are worried about the impact of inheritance tax and business property relief changes on passing their businesses to the next generation.

The response concerns me more than the statistic. Over one in five are considering a sale to an overseas buyer and 18% a UK sale, and the report warns owners may hold back investment or restructure because of tax liabilities. A decision driven by a tax bill, made under time pressure, is rarely the right one.

How Does Inheritance Tax Affect Business Succession Now?

From 6 April 2026, full 100% relief is limited to the first £2.5 million of combined agricultural and business property, with 50% relief on qualifying value above that. Any unused allowance can transfer to a surviving spouse or civil partner, and tax on qualifying property can be paid in equal annual instalments over ten years, interest-free. The GOV.UK policy paper sets out the detail.

How this lands depends on your ownership structure, valuation and family position. Take specialist tax and legal advice for your own circumstances. My focus is the commercial and leadership work alongside it.

Five Steps in Succession Planning for a Family Manufacturing Business

In my experience, the tax plan is the easier half. The challenge is making sure there is a business worth inheriting and a team capable of running it.

1. Choose and Develop Your Successor Early

Select on capability and appetite. The right successor might be a family member, a senior manager or an external hire. Give them real P&L responsibility, exposure to key customers and time across operations and commercial and finance before they take the top job.

Leadership develops through accountability, and that takes years.

2. Separate Family Roles From Business Roles

Ownership, the board and day-to-day management are three different jobs. A family member can hold shares without working in the business. Agree clear rules on who can join, how family employees are paid and who decides what, then formalise them with legal advice.

3. Strengthen the Senior Team Around the Successor

More often than not, key customer and supplier relationships sit with the founder. Transfer them deliberately through joint visits and planned handovers. An interim Commercial Director can hold the commercial side steady while a successor grows into the role, and structured change management helps the wider workforce understand what is changing and why.

4. Document How the Business Actually Runs

Much of a family manufacturer’s value lives in people’s heads: pricing logic, customer terms, process know-how and supplier history. Write it down. Map core processes, decision rights and the KPIs the board watches. Work on business processes and performance, which protects continuity and adds value whichever route you eventually take.

5. Appoint a Non-Executive Director for Your Family-Owned Manufacturer

Conversations between generations can be difficult. An independent non-executive director brings structure, challenge and a neutral voice. They hold the timeline to account, test the successor’s readiness and give lenders, customers and key staff confidence in the transition. See how non-executive support works in practice.

Looking to Prepare a Manufacturing Business for the Next Generation?

Tax rules will keep shifting. A capable successor, a strong team and well-documented operations hold their value whatever the policy. What succession needs more than anything else is focus.

I support family-owned manufacturers through succession in three ways: as a non-executive director bringing independent oversight, as an interim commercial director bridging the gap while new leadership beds in, and through strategy and change management support that keeps performance steady during the handover.

With over 25 years in food, engineering and manufacturing businesses, I understand the pressures behind these decisions. If you are thinking about the next generation, get in touch for a confidential conversation, or read more about my background.
