About McCulloch & Co
McCulloch & Co is a reputable, family-run construction and landscaping company based in High Wycombe, operating across the Home Counties. Known for delivering high-quality work and a client-first approach, we’re a growing business in need of a dedicated and proactive Admin Assistant to bring consistency, organisation, and clarity to the day-to-day.

You’ll be stepping into a role previously held by a professional virtual assistant who built strong systems and trusted relationships across the business. We’re now looking for someone who can take ownership of this function, support the Managing Director directly, and grow with us long term.

About the Role

This is a hybrid role combining remote admin support with one regular on-site working day per week (typically Fridays). You will be the key link between the Managing Director (MD), subcontractors, clients, suppliers, and the wider team - bringing order to a busy and hands-on environment. You’ll need to manage priorities, chase updates, keep information organised, and be the steady point of contact for the MD.

This role is dedicated solely to McCulloch & Co and will suit someone looking for a long-term, embedded position.

Key Responsibilities

• Inbox and calendar management, including triaging and prioritising tasks
• Scheduling meetings, calls, and reminders to keep the MD on track
• Chasing quotes, materials, paperwork, and supplier communication
• Supporting with basic finance admin (invoice tracking, Xero, expense receipts)
• Posting and scheduling company updates and visuals to social media platforms
• Liaising with subcontractors and coordinating job folders and team logistics
• Handling one-off admin projects (e.g., signage orders, childcare applications, client emails)
• Maintaining clear lines of communication with the MD and ensuring nothing slips through the net

About You

We’re looking for someone who can confidently manage their own workload, communicate clearly, and be relied upon to keep the wheels turning - even when things get busy. You’ll need set working hours where the MD can depend on you being available to respond, take action, or advise.

You will be:

• Experienced – confident in admin, diary management, and professional communication
• Proactive – able to take initiative, anticipate needs, and flag issues before they arise
• Organised – adept at managing multiple tasks, priorities, and follow-ups
• Adaptable – open to variety and growth, and comfortable in a constantly evolving business
• Committed – available at agreed hours and genuinely interested in becoming part of the team

Benefits

• Flexible working hours
• A stable role with room for long-term growth and responsibility
• Direct impact on the success and efficiency of the company
• Handover and onboarding support provided
