The Opportunity

We are currently working with a leading organisation within the BMS and Building Controls sector that is looking to appoint an experienced BMS Estimator / Technical Sales Estimator to join their growing team.

This is a technical-commercial position that sits at the heart of the sales, technical and operational functions. You will be responsible for taking BMS opportunities from the initial enquiry through to tender submission, working closely with clients, consultants, suppliers, subcontractors and internal teams throughout the process.

This is not a back-office pricing role. The successful candidate will have the opportunity to attend site surveys, support client and consultant meetings and play a key role in developing technically strong and commercially competitive BMS solutions.

  • Work closely with the sales team throughout the tender process.
  • Contribute to bid writing and wider proposal activities.

  • Knowledge of working across multiple BMS manufacturers and platforms.
  • Experience with systems such as Trend, Tridium, Schneider, Siemens, Delta, Distech or similar.
  • Experience obtaining and evaluating panel, installation and supplier quotations.
  • Strong commercial awareness and attention to detail.
  • The ability to manage multiple live tenders and competing deadlines.
  • Excellent communication skills when dealing with clients, consultants, suppliers and internal stakeholders.
  • A proactive, self-motivated and accountable approach.

  • BMS Estimator

  • Building Controls Estimator
  • BMS Proposals Engineer

  • BMS Design Engineer
  • BMS Project Engineer with estimating responsibility

We would also consider an experienced BMS Project, Design or Engineering professional who has meaningful estimating exposure and is looking to progress into a more technical-commercial position.



Why Join?

  • Competitive salary based on experience.
  • Company car with a lease value of up to -600 per month OR -600 monthly car allowance.
  • Contributory pension scheme.

The Ideal Candidate

This role would suit an experienced BMS Estimator, BMS Proposals Engineer, Applications Engineer or Technical Sales Engineer who understands both the technical and commercial sides of BMS projects.

If you have a strong BMS engineering or design background and have developed solid estimating experience, this could also be an excellent opportunity to make the next step in your career.
