Evolution NetZero exists to make Net Zero practical, defensible, and commercially viable.

Founded by Jonathan Nuttall after working with a leading London technology integrator in guest-room energy management, Evolution NetZero was built on a simple insight: most organisations don’t struggle with intent, they struggle with execution.

We work with hotels and commercial property operators who want to reduce energy waste, cut carbon, and improve ESG performance without disrupting operations or compromising guest experience.

With years of hands-on experience working directly with UK hotel groups and ownership teams, we understand the pressures of live environments, legacy systems, tight margins, and the need for decisions that stand up at board level.


Our approach is simple, sustainability must be sustainable.

We provide retrofit-ready solutions that reduce energy waste, lower CO₂ emissions, and improve ESG outcomes — all designed to integrate seamlessly into how your buildings already operate.

Our work sits across three connected pillars:

Cost & Carbon Optimisation Retrofit-first solutions with rapid, measurable ROI.
Strategic Energy & Procurement Smarter energy buying decisions, backed by independent, data-led advice and tailored procurement strategies.
Governance & Assurance Independent ESG credibility, a clear ESG starting point, and structured certification pathways for EcoVadis and B Corp.
A trustworthy, accountable partner Independent, vendor-agnostic advice focused on outcomes, not product pushing.
Professional, end-to-end services From assessment and strategy through to delivery and reporting.
Responsible, affordable pricing Commercially realistic solutions aligned to real operating budgets.
Proven energy waste reduction Practical interventions that deliver measurable results in live environments.

Frequently Asked Questions

Answers tailored to your role, pick the one that fits

Will installing your energy-saving technologies disrupt our guests or operations?

In most cases, no. Most of our solutions are retrofit-friendly and designed to work alongside your existing HVAC systems with minimal disruption. Where a particular approach could affect operations, we work with you upfront to choose the option, timing and installation schedule that best suits your hotel, so guest experience and day-to-day running stay protected throughout.

How much can we realistically save on our energy bills?

It depends on your building, systems and occupancy, which is exactly why we start with a free assessment rather than a generic figure. We draw on a range of different solutions depending on what your specific property needs, so the right combination (and the savings it delivers) varies site to site. As a guide, Guest Room Energy Management typically delivers 25–50% reductions in HVAC energy use and runtime, and Voltage Optimisation typically saves 8–12% on electrical consumption. Your free report will show which measures are most relevant to you.

What’s the typical cost and payback period for a retrofit?

Costs and payback vary by property size, existing systems and energy spend, so we don’t quote a single number upfront. Your free Cost & Energy Waste Report gives you a tailored estimate of savings and payback for your specific building before any commercial conversation.

Do you have examples of similar hotels you’ve worked with?

We work across UK hotels, commercial buildings and multi-site operators, with a particular focus on guest-room and back-of-house energy waste. We keep client details confidential, but we’re happy to talk through relevant, comparable examples and typical outcome ranges on a call.

Will this affect guest comfort or our reviews?

No, if anything it should help. Voltage optimisation and HVAC controls work invisibly in the background. Guests experience the same or better comfort levels; the only difference is less energy being wasted when rooms are unoccupied or conditions don’t require full output.
