Engineering before technology

Energy engineering for commercial sites and estates.

Understand how your business uses energy, what your site can support and which improvements deserve investment. Start with the whole picture, then compare the options.

The Energy Engineers

A clearer view of how you get, use and pay for energy.

The Energy Engineers helps commercial and industrial businesses assess their energy needs. Our expertise spans solar PV, wind and combined heat and power (CHP), alongside efficiency, electrical infrastructure and battery storage. We bring site demand, buildings, equipment and commercial priorities together to establish which options deserve investment.

Cost

Understand avoidable spend.

Separate energy prices from consumption. Look at when equipment runs, how areas are controlled and where the next improvement could make sense.

Capacity

Plan for what comes next.

Bring new equipment, electrification and expansion into the picture early. Identify the site and connection questions that could affect the plan.

Investment

Make the business case clear.

Compare technical options, customer costs and operating responsibilities. See which assumptions need testing before making a commitment.

How we approach a project

Understand the business. Then shape the project.

An energy decision connects daily operations with buildings, equipment and long-term commitments. A useful assessment brings those questions together before a solution is specified.

Explore the options
  1. 01

    Understand the site

    Start with operating hours, energy bills, interval electricity data where available, heat and fuel use, property information and the business’s future plans.

  2. 02

    Compare practical options

    Review demand, efficiency, equipment, generation and storage against the same baseline. Identify surveys, permissions and specialist checks needed.

  3. 03

    Agree the route forward

    Examine the proposal, commercial terms, responsibilities and measurement plan. Agree the scope and delivery arrangements for the chosen project.

The options follow the assessment

What could your site need?

Start with the decision you need to make. Each area has its own questions, and several may need to be considered together.

01

Energy management & controls

Understand demand and reduce unnecessary use.

Review equipment schedules, controls, maintenance and the needs of different parts of the operation. Protect safety, stock conditions and business requirements when considering changes.

  • When and where is energy being used?
  • Which controls or operating routines deserve a closer look?
02

Capacity & electrification

Plan around changing electricity needs.

Assess existing demand alongside plans for new equipment, heating, vehicle charging or buildings. Consider the electrical infrastructure and connection constraints before committing to expansion.

  • What will change in the business?
  • What capacity and connection checks are needed?
03

Onsite generation

Solar PV, wind and CHP, matched to your operation.

Compare solar PV, wind and combined heat and power against the needs of your site. Solar depends on usable space and the generation you can use. Wind needs a suitable wind resource, location and permissions. CHP produces electricity and useful heat together, so the timing and scale of heat demand are central to its assessment. Consider other generation options where relevant, with planning, grid connection, fuel, maintenance, whole-life costs and carbon performance assessed for each proposal.

  • When could the site use the electricity and any useful heat?
  • Which resource, property, planning and connection checks are needed?
04

Battery storage & flexibility

Give storage a defined operating purpose.

Assess the role of storage against demand, tariffs, controls, losses and full operating costs. Specify backup separately where it is required, and keep any trading scenario distinct from bill savings.

  • What would the battery do, and when?
  • How would costs, controls and responsibilities work?
05

Funding & ownership

Compare what you pay and what you commit to.

Consider capital purchase and funded arrangements using the actual proposed terms. Review ownership, ongoing payments, maintenance, roof rights and what happens when the arrangement ends.

  • What are the customer’s costs over the whole term?
  • Who owns, operates and maintains the equipment?

A closer look · Garden centres

Different areas. Different energy patterns.

Retail areas, cafés, growing space and seasonal trading can put different demands on a garden centre. Explore the questions that help owners, finance teams and estates managers decide what to review first.

Commercial & industrial sites

Different buildings. The same need for a sound decision.

Production, refrigeration, storage, hospitality and commercial estates bring their own operating requirements. Start with the individual site or portfolio: its demand, processes, property and future plans.

Explore your commercial site

Ownership & funding

Compare the commitment as well as the cost.

The right commercial route depends on the project and the business. Assess purchase and funded options against the same demand assumptions and comparison period.

Read the solar purchase and PPA guide

Capital purchase

Pay for the system using the business’s funds or separate finance. Include financing, maintenance, insurance and replacement costs where applicable, and confirm the ownership and operating responsibilities.

Funded onsite PPA

A provider typically owns the system and sells electricity under a power purchase agreement. A proposal may reduce upfront equipment cost, while creating ongoing payments and contractual obligations.

Availability and terms depend on site suitability and agreement. Compare price changes, purchase obligations, roof rights, maintenance, transfer and end-of-term arrangements in the actual offer.

Before the next step

A few useful starting questions.

Open a question to explore the thinking behind an energy assessment.

Is the starting point always solar?

Start with energy use, operating needs and site constraints. Our generation expertise includes solar PV, wind and CHP, alongside efficiency, infrastructure and storage. The assessment establishes which options are worth comparing for your business.

Could CHP or wind suit our site?

CHP needs a useful heat demand that aligns with electricity generation and operating hours. Wind depends on the local wind resource, exposure, available space, planning and grid connection. We assess technical fit, operating costs and carbon performance alongside alternatives before recommending a route.

What information is useful for an initial energy conversation?

A broad picture of the site, its operations and priorities helps establish the questions. Further assessment may use a year of energy bills, interval electricity data where available, building information and future plans.

Can we plan across several sites?

A consistent information pack can help compare priorities across an estate. Each site still needs its own demand, property and connection review before a proposal is developed.

Can a funded project mean no upfront equipment purchase?

Some arrangements may reduce or remove that purchase cost, subject to suitability and agreement. They can still involve energy payments, other charges and long-term obligations. Check the actual proposed terms.

Would a battery keep the business running during a power cut?

Backup needs to be an explicit design requirement. Identify the essential loads, duration and acceptable interruption, then verify the proposed equipment and configuration. Battery storage alone does not establish backup capability.

What should we check before accepting a proposal?

Check its demand and generation assumptions, costs, payments, operating responsibilities, permissions, connection requirements and measurement plan. Compare alternatives against the same baseline and keep forecasts distinct from measured performance.
