Inside Gratte Brothers' Approach to a More Resilient Supply Chain

Every building you walk into has a story you never see. Before the lights turn on, before the air conditioning hums, before the security gates recognise your badge, hundreds of skilled tradespeople spent months wiring, plumbing, fitting, and testing the systems that make a building work. These are building services. And the companies that deliver them sit at the centre of every major construction project in the country.

Gratte Brothers is one of the UK's leading independent building services companies, providing electrical, mechanical, security, and commercial catering services from a single source. They are also, somewhat remarkably, a family business. Founded in 1946 with £100, now in their third generation of Gratte family leadership, they have spent nearly 80 years building something that most companies twice their age have lost: deep, lasting relationships with the people who do the work.

That last part matters more than it sounds.

The problem no one talks about

Building services is a subcontracting business. Gratte Brothers sits between the main contractor and the specialist trades and suppliers who deliver each system. And in construction, payment flows downhill slowly. An electrician finishes a floor. An invoice is raised. Weeks pass. Sometimes months. The money arrives eventually, but in the meantime, that electrician's business is stretched, borrowing to cover materials and wages while waiting for cash that is technically already owed to them.

This is not a failure of any single company. It is how the industry has worked for decades. But that does not make it sustainable. Every month a supplier spends waiting for payment is a month of cash flow pressure, higher borrowing costs, and reduced capacity to take on the next job. Over time, the strongest supply chains quietly erode. Not because the relationships are bad, but because the financial mechanics are.

Gratte Brothers looked at this and asked a question that not enough companies ask: what would it mean for our supply chain if we gave them a choice?

What changed

Through Copay, Gratte Brothers now offers its suppliers the option to receive payment earlier than the standard terms. A supplier who values certainty and faster cash flow can opt in. Those who prefer to wait simply carry on as before. Nobody is pressured. The choice belongs to the supplier.

What makes this work is the simplicity. Gratte Brothers pays its own supply chain directly. There is no third-party lender involved, no factoring arrangement, no hidden financing layer. Copay is the technology that automates the process: calculating the discount, generating the documentation, and syncing with Gratte Brothers' existing systems through a straightforward exchange. No complex integration.

Bronwyn Miller, Group Financial Director at Gratte Brothers, put it plainly: setting up Copay took weeks, not months. The integration-free approach made it straightforward, and the team took what could have been a complex process and made it feel effortless.

Why a family business gets this right

There is something about Gratte Brothers' history that makes this partnership feel inevitable. A company that has survived and grown across three generations does not think in quarterly cycles. It thinks in decades. And when you think in decades, your supply chain is not a line item. It is the business.

The electricians, the mechanical engineers, the security installers, and the catering equipment specialists who deliver Gratte Brothers' projects are not interchangeable vendors. They are long-term partners whose skill and reliability are inseparable from the Gratte Brothers name. Protecting those relationships is not charity. It is strategy.

Offering early payment through Copay is an extension of that thinking. It signals to suppliers that Gratte Brothers takes their financial health seriously, not because a government code told them to, but because a resilient supply chain is the foundation of everything they deliver.

The bigger picture

Construction in the UK faces a familiar tension. Demand is rising. Major infrastructure, housing, and retrofit programmes need to be delivered. But the industry's ability to deliver depends on having a healthy, well-capitalised supply chain ready to do the work. When suppliers are financially strained, projects slow down. When good tradespeople leave the industry because the economics don't work, the talent pool shrinks. The effects are not dramatic. They are gradual, and by the time they become visible, they are expensive to reverse.

Companies like Gratte Brothers are proving that it does not have to work this way. By giving suppliers the flexibility to access their money sooner, they are building a supply chain that is more financially stable, more loyal, and better positioned to deliver when it matters.

Nearly 80 years ago, the Gratte family started a building services business with £100 and a belief that relationships matter. That belief has not changed. The tools to act on it have.
