Beyond day-to-day maintenance, buildings periodically require capital investment: planned refurbishments, system upgrades, fit-out works, and energy-efficiency improvements. For property managers and building owners, the challenge is finding a contractor with the technical competence to design and deliver complex works, the project management discipline to complete them on time and on budget, and enough knowledge of your operational context to minimise disruption to tenants and users during construction.
Fuimus manages building projects and minor works for commercial landlords, residential managing agents, and mixed-use estate operators across London. Our project delivery team combines in-house engineering expertise with a curated supply chain of specialist subcontractors, giving us the capability to handle everything from a single M&E upgrade to a full commercial fit-out or multi-phased refurbishment programme — all managed under a single point of contact.
Commercial fit-out requires close coordination between structural, M&E, data, and finishing trades — and a project manager who understands the constraints of an occupied building. Our fit-out projects cover Cat A and Cat B commercial office works, retail unit fit-outs, and the refurbishment of common areas in multi-tenanted commercial buildings. We work with your design team or can provide design input ourselves, and we manage the full lifecycle from initial specification through procurement, construction, snagging, and handover with a complete H&S and as-built documentation package.
For landlords managing lease events — whether fitting out vacant space to attract new tenants, or managing dilapidations at lease end — we provide fast mobilisation and documented condition assessments that support your negotiations and protect your asset value.
Building assets have finite lifespans. Boilers, chillers, lifts, roofing systems, windows, and electrical distribution equipment all reach end-of-life at different points, and planned lifecycle replacement is almost always more cost-effective than reactive replacement of failed plant. Our projects team works with building owners to develop lifecycle replacement programmes aligned with capital expenditure budgets — phasing works to distribute cost over time while prioritising the assets most critical to compliance and operational continuity.
Refurbishment works we regularly deliver include roof replacement and waterproofing, window and curtain wall replacement, communal area refurbishments for residential blocks, kitchen and bathroom renewals in BTR portfolios, and M&E distribution upgrades including consumer unit replacements, busbar upgrades, and LED lighting conversions.
With UK commercial and residential buildings under increasing pressure to reduce carbon emissions and improve energy performance ratings, many property owners are now investing in building services upgrades to improve EPC ratings, reduce energy costs, and meet net-zero commitments. Fuimus manages energy efficiency projects including heat pump installations, LED lighting retrofits, building energy management system (BEMS) upgrades, electric vehicle charging point installations, and solar PV systems for commercial rooftops.
We work with your energy advisors or can carry out preliminary energy assessments ourselves to identify the most cost-effective improvement measures for your building, modelling the investment against projected energy savings to support your business case for capital expenditure.
Every project we manage is allocated a dedicated project manager who acts as your single point of contact from inception to handover. We produce a programme at the outset showing key milestones, procurement lead times, and critical path activities, and we provide weekly progress reports throughout the construction phase. At handover, you receive a complete documentation package including as-built drawings, O&M manuals, warranties, and compliance certificates — everything you need to maintain the new assets under your ongoing FM programme.
From energy-saving upgrades to office fit-outs and small works, we manage projects end-to-end with clear timelines, compliance, and minimal disruption. Our approach combines technical expertise with transparent reporting and sustainability goals.
