Commercial Solar PV & Battery Storage Consultancy
HollenPlus helps commercial property owners and asset managers assess, design and procure solar PV and battery storage across individual buildings and portfolios.
Combining technical expertise with asset management experience, we evaluate feasibility, costs and investment returns to establish whether a project makes commercial sense.
We guide specification and competitive procurement, aligning each solution with energy demand, lease arrangements and investment objectives.
Solar PV and Battery Storage Feasibility
We assess the potential for commercial solar PV and battery storage across individual buildings and portfolios. Reviewing electricity demand, available roof space, building constraints and ownership arrangements, we establish which opportunities merit investment. We assess solar and battery storage separately and together, recommending a combined system only where the additional benefits justify the cost.
System Design and Technical Specification
We develop the project brief and coordinate specialist design around your building’s energy demand, operational needs and investment objectives. Our approach considers system sizing, roof condition, structural suitability, grid connections, export capacity and battery location. Clear specifications give contractors a consistent basis for pricing and help prevent unnecessary expenditure on oversized or unsuitable systems.
Installation Costs and Investment Returns
We build a commercial appraisal covering installation costs, projected energy savings, potential export income and ongoing expenditure. Our analysis considers maintenance, equipment degradation and replacement costs alongside payback, net present value and investment returns. Testing changes in electricity prices, occupancy and consumption helps you understand the assumptions behind the figures and make an informed investment decision.
Competitive Procurement and Contractor Selection
We manage a structured procurement process, helping clients compare contractor proposals against a clear scope and specification. We review pricing, exclusions, performance assumptions, warranties and maintenance obligations to identify the most appropriate offer. Our advice is led by your requirements, with transparent supplier selection and disclosure of any commercial relationships.
Ownership, Funding and Landlord Returns
We assess how different ownership and funding arrangements affect costs, control and financial returns. Options can include direct ownership, funded installations, power purchase agreements and roof leasing. For investment properties, we consider who funds the installation, who consumes the electricity and who receives the benefit, identifying lease, metering and consent matters for specialist review.
Portfolio Planning, Delivery and Performance
We help owners prioritise solar PV and battery storage opportunities across commercial property portfolios, aligning investment with roof replacements, refurbishments, lease events and disposal plans. We coordinate delivery and specialist commissioning, then support performance monitoring against the agreed business case. This creates a consistent approach from initial assessment through to operation, with clear responsibilities and measurable outcomes.
Securing an EPC A Rating for a 415,000 Sq Ft Logistics Facility
HollenPlus was appointed by a global investment manager to undertake a comprehensive EPC renewals across their property portfolio. The latest project has been the MEES compliance strategy and EPC renewal a for a 415,000 sq ft big-box logistics unit and its ancillary building in Yorkshire.
Utilising our data-driven building modelling approach, we successfully achieved asset-improving EPC A ratings across both units, future-proofing the development against tightening UK commercial property MEES regulations.
Proven Results Across Property Portfolios
MEES Strategy and 140x EPC Portfolio Renewal
HollenPlus successfully created and delivered a portfolio wide MEES strategy, completing an EPC renewal program for a leading UK landlord across 140x assets in 12 weeks. The project improved their EPC ratings, reducing Capex requirements and improved forecast returns.
Pathway reports were delivered and unit-specific solutions were given for EPC improvements to reach EPC B & A. The client was further able to remove a previously allocated seven figure Capex sum to achieve EPC compliance across the portfolio, from their business plans.
Strategic MEES Compliance & Decarbonisation Road Map for a Retail Warehouse Asset
As part of a wider project across a portfolio of assets, HollenPlus was appointed to secure commercial property MEES compliance through targeted, risk managed energy interventions. Through navigating the risk, strategic evaluation and structured Capex optimisation, HollenPlus was able to establish an aligned road map for the asset to reach a long-term EPC B rating.
