• Maintain accurate estimating files and assumption registers.
• Provide indicative pricing to support business development.
• Attend site visits as required and ensure tender submissions are robust, compliant and commercially sound.
• Prepare handover packs for operational teams following contract award.

What Were Looking For

• Strong civils, drainage, utilities or infrastructure experience (rail experience welcome but not essential).
• Proven experience preparing estimates up to approx. £5m.
• Good understanding of estimating software and Microsoft Excel.
• Confident presenting to senior stakeholders.
• Strong commercial thinking and attention to detail.
• Candidates who have progressed from hands‑on site roles into estimating are very welcome
• Ability to travel for client meetings and site visits.

Salary & Benefits

• £70,000 – £90,000 depending on experience
• Car allowance
• 23 days annual leave, increasing with length of service
• Company pension
• Office‑based role with at least 3 days per week on site or in the office

Why Apply?

• Work with a supportive, expanding contractor with a strong project pipeline.
• Real influence over bid strategy and tender decision‑making.
• Opportunity to mentor others and lead on major tender submissions.
• Stable, long‑term role with progression potential.
