BUILT AROUND THE SITE
Different buildings.
Different demands.
One considered plan.
Warehouses, industrial units and commercial premises each bring their own constraints. We start with the site and its energy use, then shape the installation around the practical details.
FINANCE THAT FITS YOUR BUSINESS
Let your energy
work for your cash flow.
We can tailor solar and battery finance packages so repayments cost less than the projected value of the energy your system generates.
Where suitable, this can give your business a positive cash-flow contribution while spreading the cost of the installation. We build the proposal around your site, electricity use and the available finance terms.
Discuss finance optionsTHE AIM OF YOUR FINANCE PACKAGE
Projected energy valueGreater thanFinance repayments
We compare the projected value of electricity used on site and exported to the grid with the repayments over the same period.
Finance is subject to eligibility, lender approval and agreed terms. Energy value and cash-flow outcomes are projections, not guarantees; they depend on generation, your usage and electricity tariffs.
TAX-EFFICIENT INVESTMENT
Annual Investment Allowance
Commercial solar PV and battery storage installations can qualify for the Annual Investment Allowance (AIA). Eligible businesses can deduct 100% of qualifying expenditure from taxable profits in the period the expenditure is incurred, within their available AIA limit.
The current limit is £1 million for a 12-month accounting period, shared across qualifying expenditure. Eligibility and the amount you can claim depend on your business, ownership and finance arrangements. Your accountant should confirm the treatment for your project.

Discuss your installation01
Site review & survey
We review your electricity bills, site layout and objectives, then assess the roof, electrical infrastructure and practical installation requirements.
02
Design & business case
We develop the solar and battery design, explain the projected energy value and costs, and explore suitable finance options.
03
Grid connection & permissions
We coordinate the relevant Distribution Network Operator (DNO) application and agree the connection and export arrangements. Any required site, landlord or planning permissions are addressed before work proceeds.
04
Planned installation
We agree access, delivery arrangements and any necessary electrical shutdowns with you. The work is planned around your business operations.
05
Commissioning & handover
The system is tested and commissioned. We hand over the relevant documentation and explain the controls, monitoring and warranty details.
06
Aftercare & support
We explain how to get support and discuss the maintenance and monitoring arrangements appropriate to your system.

COMMERCIAL FAQs
Your questions,
answered.
Practical answers for businesses considering solar and battery storage.
Can finance repayments be lower than the energy value?
We can tailor a package with that aim, where the project economics and available finance terms support it. The proposal compares repayments with the projected value of electricity used on site and exported over the same period. Finance is subject to eligibility and lender approval, and actual energy value can change.
Is our building suitable for solar?
We assess the available roof space, condition, structural suitability, shading, orientation and electrical infrastructure alongside your energy demand. A site review identifies the opportunities and any constraints before a design is agreed.
Can we install solar on leased premises?
It may be possible, subject to the lease and the property owner’s agreement. Tell us early if you lease the site so the required permissions, lease duration and ownership arrangements can be considered in the proposal.
Will installation disrupt our business?
We plan access and work areas with you and agree any necessary electrical shutdowns in advance. The level of disruption depends on the building and installation; we explain the programme before work starts.
How long will the project take?
The programme depends on the system size, site conditions, equipment availability and any grid or other approvals. We set out the expected stages and dependencies in your proposal, rather than promise the same timescale for every site.
What happens if the grid limits how much we can export?
The DNO may set a limit on electricity exported to the network. We account for the agreed limit in the design and projections, and assess whether on-site consumption, battery storage or an export-limitation arrangement suits the project.
Do we need battery storage as well as solar?
Not every site does. We assess when your business uses electricity and how a battery might change the value of the system. Storage can retain solar energy for use later, but its costs and expected benefits need to be assessed for your site.
What warranties and aftercare are included?
Warranty cover depends on the selected panels, inverter and battery, with different terms and conditions for each manufacturer and product. Your proposal and handover documentation set out the applicable cover and agreed support arrangements.
What information do you need to prepare a proposal?
Start with your site postcode, a recent electricity bill and a brief description of the premises. Half-hourly consumption data, if available, helps us understand demand. Let us know whether you own or lease the building and whether you are interested in finance.
