Greg Davison, Partner.

How we do it…

  • Our unique approach establishes the most cost-effective solutions to improve energy efficiency and EPC ratings through detailed energy assessments. We use advanced building survey equipment and undertake detailed investigation into every building to ensure the baseline EPC is as high as possible, thereby minimising the costs of any improvements needed. We have successfully achieved EPC B’s where previous assessments have been as low as EPC D.

    Upgrade recommendations are delivered through an asset management mindset, taking into consideration costs, the commercial value they will add, existing PPM's, service charge recoverability and practicality of delivering the works required.

    Our project management capability enables us to provide an integrated, fully managed EPC improvement service, guaranteeing landlords that the CAPEX they spend will result in the successful achievement of the target EPC.

  • We provide tailored, considered decarbonisation advice with the specific intention of maximising the value generated from building improvements, whilst simultaneously minimising costs, taking into account existing PPM's, service charge recoverability and deliverability of works.

    We assess each project individually and create design solutions aimed at achieving low-energy buildings, whilst optimising occupant comfort. This allows for a holistic approach to environmental design.

    We are experienced in Net Zero, M&E engineering, sustainability and ESG certification, whole lifecycle carbon, dynamic simulation modelling, air quality, acoustics, and daylight analysis.

  • We offer a wide range of planning services such as:

    • Whole Life Carbon Assessments (WLCA)

    • Circular Economy Statements (CES)

    • Energy & Sustainability Statements

    • BRUKL reports

    • BREEAM Services

  • Used correctly, ESG accreditations can add significant benefit to occupiers, reduce the cost of debt and enhance capital value for Landlord's.

    We offer a free ESG consultancy service, to advise upon the most beneficial ESG accreditations for a building.

    We have a range of solutions for increasing scores and ratings of existing ESG accreditations.

  • We have a range of energy efficiency solutions with guaranteed savings and free eligibility checks.

    In addition to reducing energy consumption, costs, and environmental impact, these solutions deliver savings that significantly exceed their implementation costs. This not only lowers service charge levels but also makes them recoverable through the service charge.

  • We have full design and build capability for solar installations and battery storage options, including market leading 30-year efficiency guarantees.

    We seek to maximise returns and minimise the payback period by ensuring the maximum amount of power possible is sold directly to the tenants.

    This provides additional income streams for Landlords and lower cost electricity for tenants, thereby enhancing letting prospects and renewal probability.

  • We are specialists in the delivery of low carbon fit-outs.

    We adopt a circular economy approach, re-using suitable materials and furniture to save costs (30%+) and save carbon (80%+)

    We work alongside design teams to create beautiful, sustainable spaces for landlords and tenants.

  • We partner with occupiers to help them every step of the way, from the initial building search, through to the end of the lease.

    • Due Diligence

    • Fit out Design & Testing
