End-to-End Retrofit for Commercial Real Estate
Vantage is a specialist commercial retrofit contractor delivering decarbonisation programmes across office and industrial assets throughout mainland UK. We design, manage and deliver the works ourselves – as Principal Contractor – carrying the delivery and EPC risk so you don’t have to.
Most retrofit programmes fail at the gap between strategy and delivery. Advisory reports with indicative costings leave all the risk with the investor. Vantage closes that gap. Our Clarity feasibility process locks in your target EPC rating, locks in real contractor pricing, and confirms buildability all before capital commitment. All this in as little as eight weeks – then we deliver it.
Solar installations complete in as little as four weeks. Completed solar schemes have delivered NOI uplifts of up to 3.64%, capital value increases of up to £2.1M, and rent increases of up to 46% – all on occupied, live assets with no disruption to tenants.

We design and deliver rooftop solar PV installations across commercial office and industrial buildings throughout the UK. From feasibility and planning through to installation and grid connection, we manage the full process as a single accountable contractor. Recent schemes have achieved payback periods of four years, NOI uplifts of up to 3.64%, and capital value increases of up to £2.1M - all completed in as little as four weeks on occupied assets with no disruption to tenants.

We design and deliver full building electrification programmes, removing gas-fired systems and replacing them with high-efficiency alternatives including VRF and centralised heat pumps. Managing structural, mechanical and electrical elements under a single contract removes the coordination risk that typically inflates cost and programme on M&E-led projects. Fully electric buildings eliminate gas price exposure, meet occupier net zero requirements, and directly improve EPC ratings.

Accurate sub-metering is the foundation of any credible decarbonisation strategy - without it, energy performance is unverifiable. Our installations are completed without building isolations, minimising disruption in occupied buildings. Once live, the data provides full visibility of plant and equipment usage, identifies waste, reduces service charge costs, and generates the verified operational data required for EPC assessments and ESG reporting.

LED lighting remains one of the highest-returning energy efficiency measures available. Our installations go beyond lamp replacement - we design and install advanced systems with daylight-linked and occupancy-triggered controls that eliminate unnecessary energy use across office floors, common areas and circulation. Properly specified LED systems materially improve EPC ratings at relatively low capital cost, with fast payback periods.

Occupier demand for EV charging is growing rapidly and is increasingly a factor in lease negotiations. We deliver bespoke EV charging infrastructure from feasibility through to installation, sized correctly for the building's electrical capacity and future-proofed for demand growth. As a Principal Contractor we manage the full scope, no coordination risk between multiple suppliers.
We carry the risk, not you As Principal Contractor, we underwrite the delivery and EPC outcome. Your target rating is locked in before works begin – and we are accountable for hitting it.
Clarity before capital Our Clarity™ feasibility process provides investment-grade cost certainty, verified contractor pricing and confirmed buildability before you commit capital. No indicative estimates, no surprises on site.
Delivered on occupied assets Every project we deliver is programmed around live, tenanted buildings. Our clients include institutional landlords and property funds managing occupied multi-asset UK portfolios – minimal disruption is not an aspiration, it is a requirement.
We work with your consultants We operate openly alongside your existing advisors – whether that’s a trusted cost consultant, technical due diligence team or asset manager. Our pricing, methodology and EPC modelling are fully transparent and independently verifiable. Your experts can interrogate everything we do.
Frequently Asked Questions
What is a commercial retrofit contractor? A commercial retrofit contractor designs and delivers energy efficiency and decarbonisation improvements to existing commercial buildings. This includes solar PV installation, fossil fuel removal, LED lighting, metering and high-efficiency mechanical systems. Unlike consultants who produce strategies and reports, a retrofit contractor physically delivers the works on site and is accountable for the outcome.
What does retrofit mean for commercial property? In commercial property, retrofit refers to upgrading an existing building’s energy systems and fabric to improve its EPC rating, reduce carbon emissions and lower operating costs. This can range from single measures such as solar PV or LED lighting through to full building electrification programmes replacing gas-fired systems entirely.
How long does a commercial retrofit project take? This depends on scope. Solar PV installations typically complete in four to five weeks. Full building decarbonisation programmes – including fossil fuel removal, new mechanical systems and fabric improvements – vary by asset complexity. Vantage’s Clarity™ feasibility process establishes a confirmed programme before works begin, so there are no surprises.
What EPC rating will commercial buildings need? The UK government has proposed EPC C as a minimum standard for commercially let properties by 2028, rising to EPC B by 2030. While formal confirmation is still pending, the direction is clear. Vantage’s Clarity™ process models every route to EPC A for your asset – tested, ranked and costed before capital commitment.
Do you work on occupied commercial buildings? Yes. All of our retrofit projects are delivered in occupied, tenanted buildings. We programme works specifically to minimise disruption and manage all health and safety obligations as Principal Contractor.
What areas of the UK do you cover? We deliver commercial retrofit projects across the whole of mainland UK, with offices in London and Manchester. Completed projects include sites in Newcastle, Leeds, Glasgow, Cardiff, Edinburgh, Leicester, Salford and London.
Can you guarantee the EPC rating improvement? Yes. Through our Clarity™ feasibility process we lock in the target EPC rating before works begin, with verified contractor pricing and confirmed buildability. We carry the EPC risk, not the client.
