Multiple buildings, meters and contracts
Large estates can contain many supplies, suppliers, dates, meter types and usage patterns; without a portfolio view, decisions become rushed.
Public Sector
Reduce costs across the estate without disrupting public services.
Complex estates need evidence-led procurement and investment that fits budgets, governance and the continuity of public services.
A data-led sector review
The costs across a complex estate.
Public estates use electricity and gas across civic offices, depots, libraries, leisure centres, emergency-service facilities, cultural venues and community buildings. Different services, contract dates and building conditions make portfolio control difficult.
We analyse contracts, half-hourly use, building operation and infrastructure before creating one evidence-led plan across procurement, efficiency, generation, storage and electrification within budget and governance requirements.
Common public sector energy challenges
What needs attention.
Contract exposure, consumption and site constraints are assessed together.
Ageing buildings and infrastructure
Older heating, limited controls, poor fabric and restricted capacity increase consumption and complicate improvement work.
Budgets, governance and procurement
Business cases compete for funding and must pass approvals while protecting ownership, maintenance and service continuity.
One plan across the operation
Supply, consumption and generation are connected decisions.
The right priority depends on the contracts, how the site is used, its infrastructure and future plans.
Commercial energy procurement
Review contracts across buildings or the portfolio against consumption, dates, budgets and the applicable procurement route.
Monitoring and efficiency
Identify avoidable use across HVAC, hot water, lighting, IT, depots, leisure facilities and out-of-hours equipment.
Solar PV, storage and electrification
Assess generation, storage, electric heat and charging against building condition, capacity, consumption and return.
Our process
From site data to a clear plan.
Data first, priorities second, then delivery around the operation.
Understand the estate
Collect bills, contracts, interval data, hours and information on significant buildings, equipment and planned work.
Prioritise the opportunities
Assess exposure, baseload, peaks, controls, generation and project readiness, including costs, risks and delivery.
Support delivery and review
Work around public services, access and governance, then review performance as the estate changes.
Our approach
Buy better. Reduce waste. Invest with evidence.
A lower unit rate will not correct poorly controlled buildings. A carbon target does not make every proposed project financially or technically suitable.
Plan procurement properly
Review dates, consumption and portfolio needs early enough to avoid rushed decisions.
Reduce avoidable consumption
Find buildings, controls and equipment using more energy than public services require.
Prioritise deliverable projects
Rank work by saving, capital cost, payback, carbon, readiness and operational risk.
Coordinate investment
Align work with maintenance, refurbishment, vehicle replacement and estate plans.
Why NUA Energy
A commercial view of the whole operation.
Every recommendation reflects the site, the people who use it and the evidence behind the financial case.
Decisions based on evidence
Recommendations begin with contracts, bills, interval data and genuine building use.
Transparent business cases
Costs, savings, assumptions, risks and delivery requirements are clear for internal approval.
Public services come first
Work and shutdowns are planned around staff, visitors and essential services.
Ongoing support
Contracts and improvements remain under review as budgets and service needs change.
Public Sector energy FAQs
Useful starting points for the sector.
How can public-sector organisations reduce energy costs?+
Combine better procurement with tighter control of buildings and equipment, including out-of-hours use, HVAC, lighting, demand and suitable generation.
Can NUA Energy support a compliant procurement process?+
We can support data, option appraisal, technical requirements, commercial comparisons and business-case evidence. The organisation's procurement and legal teams determine the appointment and award route.
How should projects be prioritised across a large estate?+
Assess sites consistently against use, condition, maintenance, savings, capital and constraints, separating immediate actions from projects needing surveys, networks, funding or formal procurement.
Is funding available for public-sector improvements?+
Grant, finance and delivery routes may exist depending on organisation, location, technology and timing. Funding must be formally confirmed before entering the financial case.
