Build, scale, raise, acquire and exit on your terms through a cleaner, stronger operating foundation.
What your business is worth is being decided now, by how you price work, who holds the client relationships, whether your accreditations sit with the company or with you, and how much of the revenue renews without being re-won. Every one of those is an operating decision, and every one of them is still open.

“Paul has been helping me improve my estimating, scheduling, and tracking to create bigger margins and improve productivity.”
Most installation businesses hit a ceiling somewhere between £1M and £10M. Not because the work dries up, but because everything that matters still needs the owner — pricing the job, unblocking the site, chasing the application for payment.
Rostone builds the operating structure that takes those decisions off your desk. Quoting, scheduling, commissioning, handover and collection become processes the business owns rather than tasks you carry. What follows is stronger margin per job, a business that performs without you in it, and a set of numbers that holds up when a buyer, lender or investor looks closely.
What you're left with
Every Rostone engagement leaves something behind: one place that holds how the business works and how it is performing. It is built with your managers during the engagement, around the tools you already use, so the knowledge sits with the company and not in the owner’s head.
How work is quoted, scheduled, handed over and invoiced, written down once and kept current. New starters learn from it and managers hold the standard with it.
Margin, cash, pipeline and capacity on one dashboard, fed from Xero, your CRM and other agreed sources.
The weekly and monthly management meetings, the reports that feed them, and the actions that come out of them.
Records that show a lender, investor or buyer how the business runs without the owner in every decision.
One system, owned by the business
This is where GRAX becomes practical. Grow is built here, and the evidence for Raise, Acquire and Exit is kept here.

Margin you can see – efficiency improvement through reduced friction.
Quotes that move – shorter turnaround from survey to priced quote, and a conversion rate you can forecast against.
Capacity without headcount – more delivered work per engineer, per van, per pound of overhead.
A business that runs without you –decisions, standards and relationships held by the company.
The problem is not lack of activity. It is lack of alignment. Rostone creates the operating clarity that makes everything else work.
Every business is different, but the same five breakpoints show up whenever operations stop keeping pace with the work coming in.
We work with established installers and contractors, typically £1M–£50M in revenue — owner-managed businesses, family firms and PE portfolio companies in HVAC, heat pumps, solar and battery, electrical, EV charging, building controls and retrofit.
