Installing before the deadline locks in the full savings — delay could mean paying more for the same system. Secure your survey now and protect your investment.

MCS. RECC. TrustMark. The standards that protect you.

Choosing a solar installer is not just about price or equipment — it is about legal protection, technical compliance, and long-term accountability. Our accreditations are not marketing badges; they are independently audited frameworks that govern how we design, install, contract, and support every system.

RECC, TrustMark, MCS, NAPIT and Approved Code Accreditations

MCS Certification confirms that our solar PV and battery installations meet strict UK technical standards for performance, safety, and competency. It also ensures eligibility for the Smart Export Guarantee (SEG), meaning your system can legally export electricity back to the grid. Without MCS, installations may not qualify for export payments or recognised compliance documentation.

RECC (Renewable Energy Consumer Code) membership means we operate under a Trading Standards Institute (TSI) approved consumer protection code. This legally governs our sales process, quotations, contracts, and aftercare. Customers are protected through defined complaint procedures, deposit safeguards, and access to independent dispute resolution should it ever be required.

TrustMark Registration adds a further layer of government-endorsed oversight. TrustMark businesses are monitored for financial stability, technical competence, and customer service standards. It provides an additional accountability route beyond the installer itself — protecting homeowners from rogue operators and short-term companies.

Our electrical certification and industry approvals demonstrate more than competence — they confirm we are authorised to self-certify work under UK building regulations. This ensures your installation is legally compliant, properly registered, and fully documented — critical for property resale, insurance validation, and long-term system warranties.

The "15 Years Certification" recognition reflects sustained compliance and continuous assessment within a regulated industry. Accreditation is not a one-time award — it requires ongoing audits, inspections, and adherence to evolving standards. Remaining approved year after year demonstrates operational stability and long-term accountability.

Understanding tariffs: Maximise your energy. Minimise your bills.

Understanding which energy tariff is right for your home or business can make a big difference to your bills, especially if you own an electric vehicle, have solar panels, or use battery storage. Below, we've outlined some of the most innovative and flexible tariffs currently available - each designed to help you take control of your energy usage, cut costs, and make smarter use of renewable power.

Octopus Go

Octopus Go is a popular electric vehicle (EV) tariff that offers super-low overnight electricity prices. Typically, customers get around four hours of very cheap electricity (usually between 00:30 and 04:30), making it ideal for charging an EV or running energy-hungry appliances during off-peak hours. The rest of the day is charged at a standard unit rate. The key benefit is significant cost savings for EV owners, but it can also suit solar battery owners looking to top-up overnight at low prices.

Octopus Flux

Octopus Flux is a smart export tariff ideal for solar and battery owners. It offers higher rates for exporting electricity back to the grid during peak times (usually in the evening) and lower import rates overnight. The tariff is time-of-use, meaning import and export prices vary by time of day. This structure encourages users to consume energy when it is cheaper and export when demand (and payments) are higher, maximising the value of a home battery or solar setup.

Octopus Agile

Octopus Agile is a dynamic time-of-use tariff where electricity prices change every half hour based on wholesale market rates. This means prices can be extremely low (even negative at times) during periods of high renewable generation and low demand, but can rise during peak usage. Agile is best suited to tech-savvy customers who can shift their usage to low-cost times, such as smart home users, solar battery owners, or those with automation tools.

Octopus Outgoing

Octopus Outgoing is a solar export tariff that pays customers for the electricity they send back to the grid. It can be paired with any import tariff and offers a simple flat rate (or variable rate via Outgoing Agile) for exported energy. It's a great option for solar panel owners not on a Smart Export Guarantee (SEG) deal or want a more competitive rate. It helps solar users get paid fairly for surplus energy while staying flexible with their import choices.

Eon Next Drive

E.ON Next Drive is a dual-rate tariff designed for electric vehicle owners. It offers cheaper electricity rates overnight (typically between midnight and 7am), allowing customers to charge their EVs at a much lower cost. The daytime rate is slightly higher than a standard tariff, but the savings can be substantial for those with EVs or battery systems that can use overnight charging. It's ideal for households looking to reduce the running costs of electric vehicles or shift some usage off-peak.

Solar electric frequently asked questions.

I want to reduce my bills, but is Solar PV still a good investment?

Most Solar PV systems are grid-connected, allowing electricity generated by your panels to be used instantly within your home or business. This reduces the amount of electricity you import from the grid, directly lowering your energy bills. Any excess electricity not used is exported automatically and can generate income through the Smart Export Guarantee (SEG), depending on your chosen energy supplier.

You can receive SEG payments for electricity exported back to the national grid.
The electricity you generate and use reduces your reliance on imported power, protecting you against rising energy prices.
Solar energy significantly reduces your carbon footprint.
Well-designed systems can enhance property value and energy efficiency ratings.

Solar PV systems consist of three main elements:

- an array of Solar PV modules
- an inverter(s)
- cables, monitoring equipment and switchgear

Image reference: Caplor Energy – Solar PV operation diagram.

The inverter converts the direct current (DC) electricity produced by the panels into alternating current (AC) electricity, compatible with your property's mains supply. Modern inverters include integrated safety monitoring systems that automatically disconnect in the event of grid faults, ensuring full compliance with UK regulations.

The inverter feeds electricity directly into your distribution board, meaning your home uses solar energy first before drawing from the grid — maximising efficiency and reducing bills.

Do PV systems work in the UK?

Yes. Solar PV systems perform effectively across the UK climate. While output varies seasonally, modern high-efficiency panels generate electricity even during overcast conditions. The current 0% VAT rate on residential solar and battery installations remains in place until 31 March 2027, making this a key window for homeowners considering installation before the rate reverts.

How is the solar electricity used?

The electricity generated is fed directly into your property's existing electrical circuits via the distribution board. There is no difference in quality between solar-generated electricity and grid electricity — the only difference is reduced reliance on external suppliers.

What happens if the system generates more than the building is using?

Any excess electricity is automatically exported to the grid. Exported energy is measured via your smart meter and can generate SEG payments depending on your energy tariff.

How long will my PV system last?

Most solar panels carry 25–30 year performance warranties, and inverters typically carry warranties between 5–20 years depending on the manufacturer. Many systems installed decades ago are still operational. Proper design, installation and servicing ensure long-term reliability.

What range of roof pitch is acceptable?

The ideal roof pitch is between 30° and 45°. However, systems installed between 5° and 60° still perform effectively, with only minor efficiency variance depending on orientation and shading. During your survey, we calculate precise projected output based on your specific roof characteristics.

We would like a PV system, but have heard they are costly and will take years to repay?

Systems are designed to suit individual budgets and energy needs. The current 0% VAT rate (ending 31 March 2027) reduces upfront costs for residential installations. Combined with bill savings and SEG income, many homeowners see strong returns, although actual performance depends on system size, usage and energy tariffs.

Size of System in kW	Orientation and Pitch	Shading	Electric Generated Per Year
4.35	South / 35°	Minimal	Approx. 3915 kWh

Figures shown are illustrative examples only. Actual performance, savings and SEG payments vary based on installation size, location, usage and energy tariffs.

Estimated system cost (exc VAT):	£5,300.00
VAT at 0% (until 31 March 2027):	£0.00

Do I need planning permission?

Most residential solar PV systems fall under permitted development rights. Listed buildings, conservation areas and certain protected zones may require additional approvals. We advise accordingly during your survey.

Do PV systems need regular maintenance or servicing?

Solar PV systems have minimal moving parts, but periodic servicing is recommended to ensure electrical connections, roof fixings and system performance remain optimal. Keeping panels clean and systems inspected protects long-term output and warranty conditions.

What is a Solar PV panel?

Photovoltaic panels convert sunlight into electricity using silicon cells. These cells create an electric field when exposed to light, generating usable electrical current. Panels are sealed within tempered glass and aluminium frames to ensure durability and long-term weather resistance.

What's the life expectancy of a PV system?

A well-installed solar PV system can operate effectively for 25–40 years. Degradation rates are low, and performance warranties guarantee minimum output levels over time.

What if my roof is shaded?

Shading can reduce performance, but modern systems use optimisers or microinverters to minimise impact. During your survey, we conduct shading analysis to ensure accurate performance projections.

Do I need to inform my electricity supplier if I have a PV system installed?

Yes. Your electricity supplier must be notified once the system is commissioned. We assist with the necessary documentation.

Can I heat my water with a PV system?

Yes. Solar diverters can direct surplus electricity to immersion heaters, allowing you to use excess solar generation to heat water efficiently.

What are monocrystalline and polycrystalline cells?

These terms describe the type of silicon used in panel construction. Monocrystalline panels are typically more efficient and uniform in appearance, while polycrystalline panels are slightly less efficient but cost-effective. Modern installations predominantly use high-efficiency monocrystalline technology.

How is a system sized?

Solar PV systems are modular and designed based on available roof space, energy consumption patterns and budget. We calculate system size to align with your usage and long-term energy goals.
