Job Description
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.
