Senior Estimator | Construction | London

Ambitious estimator wanted to shape the growth of a technology-driven London main contractor specialising in complex refurbishments.

The commercial refurbishment and retrofit sector in London continues to accelerate, with ageing building stock creating sustained demand for contractors who understand the intricacies of cut and carve works in occupied and heritage-sensitive environments. For estimators who thrive on getting under the skin of a project, understanding build sequences, and leveraging strong supply chain relationships, this is exactly the kind of business where your expertise will directly influence growth.

Company Overview
This award-winning London main contractor was founded in 2023 and has rapidly established itself as a specialist in complex refurbishments, retrofit projects, and high-specification fit-outs across commercial, residential, and public sector environments. Based in Fitzrovia, the business delivers projects ranging from £50k minor works to £10m+ complex schemes for clients including London boroughs, institutional landlords, and private developers. With ISO 9001, 14001, and 45001 certifications already in place and a commitment to net-zero carbon by 2030, this is a contractor that takes quality, sustainability, and governance seriously. The business is currently operating at approximately £15m turnover and actively scaling, meaning the right estimator will be joining at a genuinely pivotal moment.
