• Filing invoices, receipts, and chasing missing paperwork
• Supporting CIS and VAT reverse charge queries
• Covering the Office Manager when needed (e.g. holidays)
• Working closely with our Property Manager (Bonchurch Property Management Ltd) to track all ongoing maintenance costs

What we’re looking for:

• Strong organisation and attention to detail
• Confidence working with numbers and spreadsheets
• Experience using Sage (preferred)
• Experience/knowledge of the Construction Industry Scheme (preferred)
• Ability to manage multiple tasks and meet deadlines
• Good working knowledge of Microsoft Office (especially Excel)
• Previous experience in admin, office management, or a finance-related role
• Clear written and verbal communication skills
• A proactive, flexible attitude — happy to help wherever needed
• Trustworthy and discreet with confidential information
• Able to work independently and stay organised remotely

The role:

Initially some hours will be based in a home office with the Office Manager for an induction/training period, then remote working from home with regular meetings and calls to track progress.

• You’ll need a quiet, professional workspace at home
• 20 hours per week across 5 days (hours to be agreed)
