Keeping the built environment safe, compliant and operational

Certella is a UK-based group established to acquire and partner with specialist businesses that inspect, maintain, repair and protect critical building systems and assets.

Building exceptional businesses. Together.

We’re building Certella to help exceptional businesses achieve more together. Through strategic acquisitions and investments, our ambition is to create a leading national group in compliance and technical building services. 

We partner with established businesses with strong reputations, trusted customer relationships and skilled teams. Each company retains its brand and operational identity, while gaining access to the expertise, relationships and resources of the wider group.

Together, we can open doors to new customers, broaden our services and pursue larger opportunities. Shared support gives local teams more time to focus on their customers and their craft, while investment in people, systems and further acquisitions creates the foundations for sustained growth.

Our experience

The team behind Certella

Certella was founded by entrepreneur Phil Wood with the ambition to build a leading British group of specialist businesses that keep the built environment safe, compliant and operational.

To deliver that ambition, Phil has brought together an exceptional team of senior industry leaders, experienced acquisition professionals and specialist advisers. Their expertise spans technical services, business leadership, acquisitions, finance and law, combining entrepreneurial drive with the experience required to acquire and develop established businesses.

Businesses joining Certella can draw on this experience to strengthen performance, develop their people and pursue new opportunities, while retaining the freedom to manage day-to-day operations and customer relationships.

Our approach

A partnership built around what matters

Certella is a founder-led group. We acquire successful businesses because we value the people, expertise, reputation and customer relationships that made them successful. Our aim is to build on those strengths, not impose wholesale restructuring or make cost-cutting the basis of our investment.

01

Preserve what makes you successful

We respect established brands, customer relationships, workforce expertise and company culture. Changes should have a clear purpose and be developed with the people who know the business best.

02

Freedom to lead

Local management teams continue leading day-to-day operations, with agreed responsibilities and clear group reporting. Our approach gives capable leaders the room to lead and support when they need it.

03

Experience on hand

Owners and management teams can turn to our board and sector specialists for practical guidance on growth, financial performance, people and important business decisions.

04

Shape the transaction around your objectives

We acquire majority stakes or entire businesses. Owners may retain an equity interest and continue leading, realise part of the value they have built or plan a full exit. Different shareholders can have different objectives.

For owners

Considering what comes next?

You may want to keep leading your business while gaining the support and resources to take it further. You may want to realise part of the value you have built, arrange a partner’s departure or plan your own retirement.

We work with owners who want to remain involved and those planning a full exit, shaping the transaction and transition around their objectives.

Whatever your objectives, we begin with a direct, discreet conversation about what matters to you, your people and the future of your business.

Start a conversation

All conversations are confidential and without obligation.
