Use less from the grid.
Get more from your energy.
Start with how your business uses electricity. We then build the right combination of solar, batteries, tariffs and ongoing management around it.
Store energy for later, or charge from the grid at the correct time
A battery can store spare solar or charge from the grid, then supply your business when electricity costs more.
Buy energy at the right price
We review your import and export tariffs alongside your solar, battery and contract renewal dates.
Keep improving performance
Metering and monitoring show what you use, what you generate and where the next saving could come from.
Part of your energy strategy
Your battery can do more
than store electricity.
Intraday battery trading, explained.
Electricity prices change throughout the day. A specialist trading partner can use a compatible battery’s ability to charge and discharge to respond to those changes and seek additional income.
- 01
Charge when it makes sense
Store spare solar or charge from the grid when the expected value outweighs the cost.
- 02
Respond as prices change
The trading partner adjusts charging and discharging within your agreed site, network and battery limits.
- 03
Track the net benefit
Review bill savings and any trading return after charging costs, losses, fees and battery wear.
Bill savings
Buy less electricity at expensive times.
Your battery supplies the site when it is useful. You continue to pay your electricity supplier for grid imports, including energy used to charge the battery.
Trading income
Earn from the battery’s flexibility.
Where suitable, a trading partner accesses the wholesale market and accounts for trading returns separately under your agreement. You do not need to trade yourself.
We model these together so the same battery capacity is not promised twice. Trading income is variable; suitability depends on your tariff, metering, connection and equipment.
How we work
One plan.
Ongoing improvement.
From the first review to the next tariff renewal, CS Concept keeps the equipment, energy costs and commercial results connected.

- 02
Build the right plan
Compare solar, storage and trading opportunities, including installation and ongoing costs.
- 03
Install & connect
Design and deliver the agreed system, with the required site and network checks.
- 04
Manage & optimise
Monitor performance, maintain the equipment and coordinate tariffs and suitable battery trading.
- 05
Review every year
Compare actual results with the plan and adjust as your business and the market change.
Every annual review feeds back into your energy plan.

Management & maintenance
We stay involved
after installation.
One annual management agreement keeps your system monitored, maintained and reviewed. Available for new projects and suitable existing assets.
Monitor & respond
Track generation and battery performance, investigate alerts and coordinate fault response.
Maintain & inspect
Routine operations and maintenance (O&M), plus annual electrical inspection and certification, are included in the agreed management fee.
Report & review
See how the system is performing and review savings, tariffs and further opportunities each year.
The service scope is agreed for your site. Replacement parts and major remedial work outside that scope are quoted separately.
When your site needs a more detailed review
Energy across more than one site
We can assess whether surplus renewable generation at one building can support another through a suitable supplier arrangement.
Explore energy sharing (P442)Energy-intensive businesses
We consider any relevant energy support alongside solar, storage and procurement to assess the whole financial picture.
Read about EII supportEnergy Intensive Industries (EII) support
Whole energy optimisation
Protect the support. Then optimise the site.
For a high consumption business, EII support can be worth thousands, or tens of thousands, of pounds each year. It should be understood before changes are made to the site's energy profile.
Check eligibility
Review the business, site activity and available evidence against the current eligibility requirements.
Quantify the value
Establish the support currently received, or potentially available, so it is visible in the business case.
Model the interaction
Test how solar, battery storage, procurement and changing consumption could affect the total financial position.
Optimise the whole position
Build the energy strategy around the strongest combined outcome, then keep it under review as the site changes.
Our starting pointWe do not start by selling the biggest system.
We start by understanding the complete financial position, then recommend the combination that delivers the best overall result.
Start an EII review02 / For commercial landlords
Your roof generates power.
Your property generates income.
In a landlord-funded solar project, you own the system. Your tenant buys the electricity it uses at an agreed price. CS Concept designs, delivers and manages the system.
Fund & own the solar.
You invest in the system and receive income from the solar electricity sold to your tenant.
Use & pay for the power.
The tenant buys metered solar electricity at an agreed price, with the aim of reducing its energy bill.
Deliver & manage it.
We assess the project, coordinate installation, monitor performance and provide ongoing maintenance.
How the money works
Tenant pays for solar used → You receive energy income → Agreed costs are deducted to show your net return.
The tenant still buys any additional electricity from its supplier. Expected savings and landlord returns are assessed for each building before an agreement is made.
Review your property or portfolioFrom the first roof to the whole portfolio
How it works,
step by step.
Start with one building or a full estate. The process is the same: establish the opportunity, agree the terms and keep the system working.
- 01
Review the property
We check the roof, electricity use, lease terms and grid connection. For a portfolio, we identify which buildings to start with.
- 02
Agree the business case
You see the installation cost, expected energy income, tenant saving and ongoing costs before deciding whether to proceed.
- 03
Set the tenant agreement
Agree who owns the system, the solar electricity price, metering and responsibilities, including what happens at a lease change.
- 04
Install & start supplying
CS Concept coordinates delivery. Metering records the solar electricity supplied to the tenant and any export.
- 05
Manage & review
We monitor and maintain the system, report performance and review the commercial results across your property or portfolio.
After installation
One annual management fee.
Monitoring, routine operations and maintenance, reporting and annual electrical inspection and certification are included within the agreed scope.
The landlord questions
Know where
you stand.
Funding, tenants, payments and the day-to-day responsibilities.
Who pays for the installation?
In the landlord-funded model, you pay for and own the system. We can also assess tenant-funded or third-party-funded options where suitable. Ownership, income and responsibilities depend on the funding structure agreed.
How does the tenant pay for the electricity?
The tenant pays for metered solar electricity under an agreed energy supply contract, often called a power purchase agreement (PPA). The price and any future price changes are agreed in advance. Metering, billing and collection responsibilities are set out before installation.
Does the tenant still need an electricity supplier?
Yes. Solar will not cover demand at all times. The tenant retains a grid supply for the remaining electricity they need and continues to pay the applicable supplier charges.
What if the tenant leaves or the building is empty?
We address tenant changes, vacant periods, roof access and future lease arrangements before contracts are agreed. On-site energy income can fall during a vacancy, so the business case must account for this.
What happens to electricity the tenant does not use?
Depending on the site and permissions, spare electricity may be stored in a battery or sold under an export arrangement. We can also assess energy sharing between sites. Each option is modelled separately.
Can you do this across several properties?
Yes. We review the portfolio, prioritise suitable buildings and manage each installation through one coordinated programme. You can start with one property and build from there.
Useful answers
A few practical questions.
Do I need solar panels to have a battery?
Not necessarily. A battery can charge from the grid and may support bill savings and trading without solar. We assess your demand, tariff, connection and equipment before recommending a system.
Is battery trading income guaranteed?
No. Returns depend on market prices, battery availability, operating limits and the trading agreement. We show potential trading income separately from forecast bill savings, with charging costs, losses, fees and battery wear included in the assessment.
Can you manage an existing solar or battery system?
Yes. We review its condition, monitoring and documentation, then agree a suitable management and maintenance scope.
What does the management fee include?
Monitoring, fault detection, reporting, routine O&M and annual electrical inspection and certification are included within the agreed scope. Replacement parts and major remedial works outside that scope are identified separately before work proceeds.
