Job Description

We are looking for a reliable, organised and detail-oriented Office Administrator / Estimating Administrator to support the daily operations of a busy plumbing, heating and property refurbishment business.

This is a varied office-based role covering general administration, invoicing, quotations, pricing updates and business support. The successful candidate will help keep office operations organised and ensure that pricing, financial records and job-related paperwork are maintained accurately.

The role focuses on supporting existing operations and pricing processes rather than preparing competitive tenders.

- Preparing and amending quotations using existing pricing lists, templates and agreed rates.
- Maintaining and updating pricing lists and supplier costs.
- Preparing and processing invoices, purchase orders and other financial paperwork.
- Checking invoices, costs and figures for accuracy.
- Tracking outstanding invoices and following up on overdue payments.
- Maintaining accurate customer records, job files and administrative documents.
- Liaising with customers, suppliers, plumbers, engineers and subcontractors.
- Supporting job scheduling and coordinating appointments where required.
- Assisting with general business administration and keeping records up to date.

Requirements

- Previous experience in office administration, accounts administration, estimating administration or a similar role.
- Good Microsoft Office skills, particularly Excel and Outlook.
- Strong numerical skills and attention to detail.
- Excellent written and spoken English.
- Good organisational, communication and time-management skills.
- Ability to manage multiple tasks, work independently and meet deadlines.

- Experience with quotations, invoices, pricing lists or purchase orders is an advantage.
- Experience in plumbing, heating, construction or property maintenance is desirable but not essential
