Funding options
Power Purchase Agreement (PPA)
£0 Upfront Cost
Not ready to invest upfront
For businesses that want the benefits of solar without the upfront capital outlay, a Power Purchase Agreement offers a straightforward alternative. You get a fully installed commercial solar system at no initial cost, we take care of the installation, ownership, and maintenance, and you simply pay for the electricity the system generates.
The rate you pay under a PPA is set below the standard grid rate, meaning you save on your electricity bills from the moment the system goes live. There are no capital costs, no maintenance responsibilities, and no system ownership risk, just cheaper, cleaner electricity delivered directly to your business.
PPAs are typically structured over a 10–25 year term, with the electricity rate either fixed or index-linked depending on the agreement. At the end of the term, options usually include renewing the agreement, purchasing the system outright, or having it removed at no cost.
For SME business owners who want to reduce energy costs without tying up capital, a PPA is a low-risk, high-impact route into commercial solar.
Capital Expenditure
(CAPEX)
100% Capital allowance available
For businesses ready to invest directly in their energy future
Purchasing a solar system outright is the most straightforward route, and the one that delivers the greatest long-term return.
With CAPEX you own the system from day one, meaning every unit of electricity your panels generate is yours at zero cost. Most commercial solar installations pay back the initial investment within 4–7 years, after which the system continues generating effectively free electricity for 25+ years.
CAPEX also comes with a significant tax advantage. Commercial solar qualifies for 100% capital allowances under the UK government's Full Expensing scheme, meaning the full cost of the system can be deducted from your taxable profits in the year of purchase — substantially reducing the effective cost of your investment.
For SME business owners who have the capital available, a direct purchase is one of the most reliable and tangible investments a business can make in its own infrastructure.
"I was responsible for coordinating the installation of a solar PV system across a number of buildings involving complex roof aspects and electrical arrangements. Electrasure were professional, reliable, and straightforward to work with throughout. Very trustworthy and respectable on site — they turned up when they said they would and delivered in the agreed timeframe."

How much could commercial solar reduce my electricity bills?
1
Most commercial solar installations reduce electricity costs by 50–75%, depending on your energy usage, roof size, and system specification. Businesses with high daytime energy consumption — such as manufacturers, warehouses, and food production facilities — tend to see the greatest savings. As part of your free consultation, we provide a detailed ROI projection specific to your site so you know exactly what to expect before committing to anything.
How long does a commercial solar installation take?
2
Most commercial solar installations are completed within 2–5 days depending on system size and roof complexity. The process from initial consultation to a live system typically takes 6–12 weeks, which includes the site survey, system design, DNO application, and installation. We manage the entire process and keep you updated at every stage.
Do I need planning permission for commercial solar panels?
3
In most cases, commercial solar installations fall under permitted development rights and do not require planning permission. There are exceptions — listed buildings, conservation areas, and some larger installations may require consent. We assess this as part of your initial site survey and handle any necessary applications on your behalf.
What is the typical payback period for a commercial solar system?
4
Most commercial solar systems pay back the initial investment within 4–7 years. After payback, the system continues generating effectively free electricity for the remaining lifespan — typically 25 years or more. Businesses that opt for a Power Purchase Agreement (PPA) see savings from day one with no upfront investment required.
What happens if my business generates more solar energy than it uses?
5
Any surplus electricity your system generates can be exported back to the grid under the Smart Export Guarantee (SEG). We handle the SEG setup as part of your installation, ensuring you receive a payment for every unit of electricity you export. The exact rate depends on your energy supplier.
Can solar panels be installed on any commercial roof?
6
Most commercial roofs are suitable for solar installation, including flat roofs, pitched roofs, and metal profile roofs common on industrial and warehouse buildings. South, southeast, and southwest facing roofs deliver the best generation output, but east and west facing roofs can also be viable depending on your energy profile. We carry out a full structural and electrical assessment as part of your site survey.
7
Do you handle the DNO application and grid connection?
Yes — we manage the full DNO (Distribution Network Operator) application and grid connection process on your behalf. This is often one of the more complex parts of a commercial solar project, and our team has extensive experience navigating it efficiently to avoid delays.
What accreditations does Electrasure hold for solar installation?
8
Electrasure holds MCS (Microgeneration Certification Scheme), NICEIC, NAPIT, CHAS, and RECC accreditations. MCS certification in particular is a requirement for accessing the Smart Export Guarantee and demonstrates that our installations meet the highest standards for renewable energy systems.
