Senior Estimator

We're a London-based principal contractor specialising in complex retrofit, working across commercial, residential, heritage and public sector projects from £50k to £10m.

We're hiring a Senior Estimator to lead the preparation and submission of accurate, competitive tenders, and to help build out our estimating function as the business grows. Reporting to our Pre-Construction Lead, you'll own full tenders end-to-end, help manage and develop the estimating team, and play a real role in shaping how we win work.

• Owning the preparation and submission of full tenders from enquiry through to award
• Leading take-offs, pricing, and cost build-ups across trades and disciplines
• Driving value engineering and buildability solutions to make our bids more competitive
• Managing supply chain engagement and developing long‑term subcontractor relationships
• Leading structured handovers to delivery teams to keep estimating and live projects aligned
• Mentoring and developing estimators as the team grows
• Working closely with the Commercial Director and Pre-Construction Lead on bid strategy and risk

• A strong estimator with main contractor experience, ideally in sub-£10m complex retrofit
• Confident running tenders end-to-end across a range of project types and contract forms
• Proven ability to drive value engineering and find competitive edge in submissions
• Sharp on supply chain: knows the right people, gets the right prices, builds the right relationships
• Comfortable leading and developing a team, with the judgement to know when to push back on a bid

We're growing, the pipeline is strong, and we're building a pre-con function that takes work‑winning seriously. You'll have real ownership of how tenders are run, a senior‑led team backing you, and the chance to build out the estimating function as Bloom scales.

If you're an experienced estimator who wants to lead, not just price, this is one to look at.
