Job Description

InstaGroup is a nationally recognised leader in energy efficiency and renewable solutions, known for our technical expertise and high-quality installations. Since 1980, we have delivered innovative, cost-effective solutions that improve building performance, reduce energy costs, and lower carbon emissions - giving our customers peace of mind.

Our services span insulation, solar energy, and heating solutions, supported by a comprehensive product offering. We are committed to sustainability, with over 80% of the materials we use sourced from recycled or sustainable origins.

Our Mission

Our mission is to transform the energy sector through innovative, sustainable solutions that exceed customer expectations. Guided by excellence, integrity, and environmental responsibility, we strive to lead energy advancement while making a positive impact on the world and creating a more sustainable future for generations to come.

We're looking for an experienced and commercially minded Group Financial Controller to join us at a genuinely exciting stage in our growth journey.

This is more than a technical finance role. It's an opportunity to step into a visible, hands-on leadership position where you'll shape the future of the finance function and act as a trusted partner to the CFO and Senior Leadership Team.

You'll lead a motivated team of six, strengthen our financial infrastructure and help drive strategic decision-making across the business. If you're someone who wants to influence outcomes - not just report numbers - this role offers real impact and progression.

The Opportunity

As Group Financial Controller, you will take ownership of the full finance function across the Group. From delivering high-quality management information to leading audit, tax and statutory reporting, you will ensure strong financial governance while enabling growth.

You'll combine operational excellence with commercial insight - building a finance function that is both robust and forward-looking.

This role is office based and ideal for a fully qualified accountant who thrives in an agile, fast-paced SME environment and enjoys leading from the front.

• Overseeing compliance across VAT, Corporation Tax, PAYE and related filings
• Managing payroll review and annual compliance processes (P11Ds, PSA etc.)

Systems & Process Leadership

• Managing and optimising Microsoft Dynamics NAV (with future improvements in mind)
• Driving smarter reporting, workflows and automation
• Embedding scalable systems to support future growth

Leadership & Team Development

• Leading, developing and structuring a high-performing finance function
• Coaching and mentoring team members
• Fostering a culture of accountability, curiosity and continuous improvement
• Acting as a key member of the Management Team and deputising for the CFO when required

What We're Looking For

We're seeking someone who combines technical strength with commercial awareness and leadership presence.

• Fully qualified accountant (ACCA / CIMA or equivalent)
• 5+ years in a Financial Controller or similar senior finance role
• Proven experience in a fast-paced, mid-sized or SME environment
• Strong financial and management accounting expertise
• Confident in budgeting, forecasting and financial modelling
• Deep understanding of cashflow management and balance sheet control
• Comfortable managing multiple priorities and projects
• Advanced Excel skills and strong systems capability (Dynamics experience helpful but not essential)

But beyond qualifications, we're looking for someone who:

• Thinks commercially and challenges constructively
• Builds trusted relationships across finance and non-finance teams
• Communicates financial insight clearly and confidently
• Balances detail with big-picture thinking
• Brings energy, resilience and a solutions-focused mindset.

What Success Looks Like

In this role, you will:

• Deliver clear, timely financial insight that informs leadership decisions
• Create visibility around performance, risks and opportunities
• Build a scalable, well-controlled finance infrastructure
• Develop a confident, capable finance team
• Drive improvements that increase efficiency and effectiveness
• Become a trusted partner to senior stakeholders across the business

Why Join Us?

• A visible and influential leadership role
