Company: RPM Installations - Established 1983

Established in 1983, RPM Installations is a respected mechanical services contractor delivering high-quality HVAC solutions across London and the South East. We work across the commercial, high-end residential, education, and public sectors, offering mechanical design, installation, and commissioning services.

Following a recent change of ownership, the business is entering a significant phase of modernisation, investment, and process improvement.

The Role

This is a key senior hire. You will be responsible for all mechanical estimating activities across the business and will play a pivotal role in developing a formal estimating department.

Lead all mechanical estimating for tenders ranging from small works to multi-million-pound packages. Carry out detailed take-offs, cost analysis, and tender submissions using drawings, specifications, and site information. Review and improve our current pricing methods (largely Excel-based) and implement a consistent, structured estimating system. Establish best-practice procedures, databases, templates, and cost libraries. Liaise with supply chain and subcontractors across mechanical, electrical, and BMS packages. Provide value-engineering options and technical input during bid stages. Support business strategy by helping to forecast, analyse, and improve our win rates. Work with project managers to ensure smooth handover of successful bids into delivery.
You will report directly to senior management and have the autonomy to build and shape an estimating function as the business continues to expand.
