Commercial & Facilities

Cut running cost and protect every asset's value, before the EPC deadlines bite.

Energy is your biggest controllable cost and roughly a quarter of it is wasted, while tightening efficiency standards threaten to strand the buildings that miss them.

We cut energy, water and carbon across your portfolio and evidence it for disclosure, on the buildings you already operate, with no disruption to occupiers.

Independent evidence: building energy optimisation delivers 15 to 30% savings, with heating, ventilation and cooling the single largest opportunity.

The challenge

Your biggest cost is wasted, and the assets that miss EPC are about to strand

Facilities and property teams are carrying rising energy bills and tightening efficiency standards on the same buildings, with disclosure duties expanding underneath both.

Energy is the largest controllable overhead, and commercial buildings waste roughly 25 to 30% of it, with heating, ventilation and cooling alone accounting for about 54% of use. Every wasted kilowatt is margin and carbon you are paying for twice.

Minimum energy efficiency standards are tightening from EPC E today towards a proposed EPC C by 2027 and EPC B by 2030. Around 58% of central London office stock already sits below EPC B, and the share of commercial property failing the standard could rise from 10% to 85% under an EPC-B minimum. A building that cannot be let is a stranded asset.

At the same time, carbon and energy disclosure is expanding, from SECR, already mandatory for around 11,900 companies, to the new UK Sustainability Reporting Standards from the 2026 financial year. What you cannot measure, you now have to report.

Our approach

How we cut cost and protect value without disrupting the building

We improve the performance of the buildings you already run, so running cost and carbon fall and the asset stays lettable, with no capital rebuild and no disruption to occupiers.

Energy, water and air are optimised in place, on live plant and occupied floors, so the savings land without a refit. The result is lower operating cost, a stronger EPC position and a smaller carbon footprint on the same building.

Every reduction is measured, so the same work that lowers your bills also produces the auditable evidence your SECR and UK SRS disclosures need. One accountable partner carries it across the portfolio.

What you get

Lower cost, protected value, disclosure evidenced

Cost

Cut your biggest controllable cost

Take 15 to 30% out of building energy through optimisation, with heating, ventilation and cooling the single largest opportunity, measured and reportable against your baseline.

Risk

Protect lettability and asset value

Move buildings up the EPC scale before tightening minimum standards strand them, so the asset stays lettable and holds its value through 2027 and 2030.

Obligation

Evidence your disclosure

Produce the auditable energy and carbon data your SECR and UK SRS reporting require, measured rather than estimated.

Risk

Healthier air for occupiers

Cleaner indoor air that measurably supports occupier wellbeing and productivity, the differentiator that keeps space let, with no ozone or harmful byproducts.

Cost

Safe water, no toxic residue

Effective water and surface disinfection with no toxic chemical residue, including independently verified removal of 99.99% of biofilm (ASTM E2799).

Obligation

Generate energy from the building

Recover energy from the water already moving through your building systems, with no new civil infrastructure, contributing to your net zero target.

Evidence

Measured savings, not estimates

Independently evidenced, reportable against your baseline.

Results you can take to an asset review

Hospitality estate

A private estate eliminated biofilm using a fraction of the previous chemical volume

Over a ten-week trial, biofilm and algae were eradicated from the water system with zero Legionella, E. coli or coliforms detected, verified by an independent water-authority laboratory.

Facilities water

A major facility eliminated recurring waterborne pathogens in four days

Bioload fell to 0 cfu/g across every test point after years of failed chemical dosing, confirmed by a UKAS-accredited laboratory, and held on routine maintenance dosing.

Leisure

Commercial pools reduced sanitiser demand with superior water clarity

Supplemental treatment lowered the reliance on sanitiser chemistry while improving water clarity and swimmer safety, with mineral scaling brought under control.

Before you commit

Clear payback, no disruption, fully reportable

The questions facilities and property teams ask first are the right ones: what is the payback, will it disrupt occupiers, and is the saving real and reportable?

So we answer all three up front. Savings are measured against your baseline, not estimated, so the business case and the disclosure evidence come from the same work. It is delivered in place, on occupied buildings, with no refit and no disruption to occupiers, and it is designed to move the asset up the EPC scale before tightening standards strand it. We start with your highest-cost or hardest-to-let building, prove the result, then roll it across the portfolio.

Every saving is measured against your baseline and reportable.
Questions answered
What is the payback, and will it disrupt occupiers?

Savings are measured against your baseline so the payback is explicit before you commit, and the work is delivered in place on occupied buildings with no refit and no disruption to occupiers.

Will it keep our buildings lettable as EPC standards tighten?

Yes. The work is designed to move buildings up the EPC scale ahead of the proposed EPC C by 2027 and EPC B by 2030 minimums, so the asset stays lettable and holds its value.

Is the saving real and reportable, or just an estimate?

It is measured against your baseline, so the same work that cuts your bills produces the auditable energy and carbon evidence your SECR and UK SRS disclosures require.

Does it require capital works or new plant?

No. Energy, water and air are optimised on the plant and systems you already run, so the savings land without a capital rebuild.

How does cleaner air help the business case?

Clean indoor air is independently linked to measurably better occupier cognition, wellbeing and productivity, which supports retention and lettability, delivered with no ozone or harmful byproducts.
