Office Administrator / Service Desk Coordinator
Battersea, London (Full-Time, On-Site)
Heat-Plex Limited
About Heat-Plex
Heat-Plex is a fast-growing, premium plumbing, heating and gas company operating across London. We work with private homeowners, landlords and managing agents, delivering high standards of workmanship and customer care.
We are approaching £1.5m+ turnover and are now building a stronger in-house office team to support our next stage of growth.
This is not a quiet reception role. It is a key position at the centre of a busy operations team.
The Role
- You will be the first point of contact for our customers and engineers.
- Your role is to keep the diary flowing, ensure communication is clear and professional, and help the business operate efficiently day to day.
- You will work closely with our Operations Manager and leadership team.
Core Responsibilities
- Answer all incoming calls professionally and confidently
- Book jobs accurately into our CRM system
- Manage customer emails and respond with clear, well-written communication
- Coordinate engineer diaries and confirm appointments
- Follow up on quotations and outstanding approvals
- Support with aftercare and customer satisfaction follow-ups
- Assist with general office coordination and admin tasks
- Help maintain high standards of organisation and workflow
You will play a direct role in improving customer experience and helping the company grow.
What We’re Looking For
We are looking for someone who:
- Speaks clearly and confidently on the phone
- Writes professional, polished emails
- Is highly organised and calm under pressure
- Can manage multiple tasks without losing detail
- Is proactive and takes ownership rather than waiting for instruction
- Enjoys working in a fast-paced environment
- Wants to grow with a business, not just “do a job”
Previous administrative or service desk experience is preferred.
Experience in trades, property or construction environments is a bonus — but not essential.
Systems
Experience with:
- Microsoft Office
- CRM systems (training provided)
- Scheduling or diary management software
What We Offer
- Competitive salary (based on experience)
- A growing, ambitious company environment
- Opportunity to develop into a senior office or operations role
- Supportive team culture
- Modern office space in Battersea
Important
This role is fully on-site. We are building a strong office culture and require someone present and engaged with the team.
If you are organised, confident and ready to take ownership in a growing business, we would love to hear from you.
