Core Integrated Group

Core Integrated Group is a building services group working with property managers, facilities managers, managing agents, and business owners across London and the South East.

We provide mechanical and electrical maintenance, M&E project work, commercial fit-outs, and post-installation finishing — all delivered by a single, connected team. That means one relationship, one point of accountability, and a consistent standard of work across everything we do.

We are straightforward to work with, technically capable, and focused on long-term partnerships rather than one-off contracts. The buildings we look after stay well-maintained, their systems remain compliant, and the people who manage them can get on with other things.

Three Divisions. One Team.

Core Maintenance Services

Planned preventive maintenance, reactive callouts, and compliance servicing. We keep your building’s mechanical and electrical systems performing properly, document everything clearly, and respond quickly when something goes wrong.

Core Technical Services

M&E installations, commercial fit-outs, and infrastructure upgrades. We manage the full technical scope — from initial survey and design through to commissioning and handover — working alongside your project team without creating programme problems.

Core Interior Services

Make good and decoration services following M&E works and fit-outs. We restore building fabric and finish spaces properly, so the technical work is never the thing people notice.

What We’re Here To Do

We maintain safe, compliant buildings that work properly for the people using them.
