Business Development Manager | HVAC Specification Sales

Location: UK National (Ideally London, South East or South Midlands)
Salary: £65,000 to £70,000 Basic + 20% Bonus + Company Car + Benefits
Sector: Commercial HVAC / Mechanical Building Services

The Opportunity

We are working with an established international manufacturer of specialist HVAC technologies that is looking to appoint an experienced Business Development Manager to strengthen its presence within the UK specification market.

This is a strategically important appointment, focused on developing relationships with M&E consulting engineers, identifying commercial and industrial projects at the early design stages, and influencing the specification of technical HVAC solutions.

The business has an established reputation for engineering quality and innovation, with a product portfolio covering humidification, heat recovery and associated HVAC technologies.

The successful candidate will play a key role in generating new project opportunities, developing consultant relationships and increasing the manufacturer’s presence within commercial building specifications.

Key Responsibilities

  • Develop and maintain relationships with M&E consulting engineers, mechanical design consultants and other specification decision-makers across the UK.

  • Identify commercial and industrial building projects at the early design stages and engage with consultants before equipment specifications are finalised.

  • Deliver technical presentations, CPDs and product demonstrations to consulting engineers and other relevant stakeholders.

  • Influence the specification of HVAC solutions through technical consultation, product knowledge and an understanding of project requirements.

  • Track opportunities through the design, tender and procurement stages, working with contractors, OEMs and internal sales colleagues to maximise specification conversion.

  • Identify new market opportunities across applications including commercial buildings, healthcare, data centres and industrial facilities.

  • Develop and manage a pipeline of specification opportunities, maintaining visibility of project progress and future revenue potential.

  • Collaborate with technical and commercial colleagues to ensure that proposed solutions meet project requirements.

Candidate Requirements

We are particularly interested in speaking with commercially driven HVAC sales professionals who have established experience of consultant-led specification sales.

Essential experience:

  • Proven experience in technical sales or business development within the commercial HVAC or mechanical building services sector.

  • A track record of developing relationships with M&E consulting engineers and influencing product specifications.

  • Experience identifying and developing project opportunities during the early design stages.

  • Good understanding of the construction project lifecycle, including consultant specification, tendering and contractor selection.

  • Sufficient technical knowledge to engage confidently with mechanical engineers and discuss HVAC system applications.

  • Strong presentation, relationship development and new business skills.

  • Willingness to travel nationally, with a particular emphasis on London-based consulting practices.

Particularly relevant product backgrounds include:

  • Air Handling Units (AHUs)

  • Commercial and industrial ventilation

  • Heat recovery systems

  • Humidification and humidity control

  • Commercial cooling and chillers

  • Applied HVAC and other engineered mechanical building services equipment

Direct experience of humidification is not essential. We are equally interested in candidates from related mechanical HVAC backgrounds who can demonstrate strong specification sales experience and relevant consultant relationships.

An engineering qualification would be advantageous but is not a prerequisite.

What’s on Offer?

  • Basic salary: £65,000 to £70,000, depending on experience

  • Bonus: Approximately 20%

  • Company car

  • Pension and additional benefits

  • National, field-based position with flexibility to manage your territory

  • Established international manufacturer with a technically differentiated product portfolio

  • Opportunity to play a significant role in developing specification-led business across the UK

Location

This is a national position, although candidates will ideally be based in London, the South East or South Midlands, allowing regular access to major M&E consulting practices.

There is no requirement for regular office attendance; the emphasis is on developing customer relationships and identifying project opportunities.

Interested?

If you have experience selling technical HVAC solutions through M&E consultants and enjoy developing business by influencing specifications at the earliest stages of a project, we’d be interested in hearing from you.
