Why Solar for Your Business?

It's not just about saving money — it's about taking control

Too often, businesses fall victim to market volatility and international events that send energy costs spiralling. Our goal is simple: to give your business cost certainty and supply assurance through onsite solar and battery generation — so you can plan, operate, and grow with confidence.

Cost Certainty

Lock in your electricity costs with onsite generation. Unlike grid tariffs, solar energy gives you a predictable, stable unit cost over the lifetime of your system — typically 25+ years.

Supply Assurance

Generate your own electricity on-site and reduce dependency on the national grid. With battery storage, you can maintain operations even during outages or supply disruptions.

Immune to Market Forces

Geopolitical events, international energy markets, and wholesale price spikes won't affect the electricity you generate yourself. Your energy becomes a stable business asset.

Reduced Operating Costs

Offset a significant portion of your energy consumption with solar generation, directly reducing your operating expenses and improving your business's bottom line.

Battery Energy Storage

Smart battery storage — save costs and earn income from the energy markets

Today's battery systems come with dynamic trading software that actively trades energy markets on your behalf. Your battery charges at the cheapest times and discharges at peak price periods — not just reducing your bill, but in many cases generating an income by selling stored energy back into the grid at peak market rates.

Peak Demand Shifting

The battery charges at the cheapest off-peak rates and discharges during expensive peak periods, dramatically reducing your grid import costs — with no change to your operations.

Dynamic Market Trading

Built-in trading software actively participates in energy markets, automatically selling stored energy at peak price windows — turning your battery into an income-generating asset.

Supply Resilience

With stored energy on-site, your business maintains continuity even during grid disruptions — reducing vulnerability to supply interruptions.

Real-World Reference Case

A commercial site consuming 309,437 kWh/year (£73,072 at market rates) achieved savings of £5,794 (7.9%) on a fixed tariff and £11,386 (15.6%) on a dynamic tariff — purely through battery demand-shifting and dynamic market trading, with no change to operations.

These figures reflect demand-shifting savings only. Dynamic trading income will vary based on market conditions and is additional to the figures shown below.

Choosing a Solar Installer

A guide for domestic homeowners: what to look for, and the most common mistakes.

MCS certification, checked properly

MCS makes the system eligible for Smart Export Guarantee (SEG) payments. Check the installer on the MCS register yourself, a website logo isn't enough. Confirm the MCS certificate will be issued in your name after the install.

Consumer code membership (RECC or HIES)

MCS no longer requires a consumer code after its 2025–26 redevelopment. MCS covers the technical standard; the consumer code covers sales conduct, contract terms, deposit protection and what happens if the firm ceases trading. Ask why if one is missing.

Deposit and workmanship protection

Deposits should be modest and protected. Ask for an insurance-backed workmanship warranty that survives the installer going out of business, and get the name of the insurer.

A site-specific design, not a brochure quote

A good quote is based on a proper survey: roof orientation, pitch and shading, structural condition, consumer unit and earthing, and where the inverter and battery will go. The generation estimate should follow the MCS method and include the shade factor.

Named components

Ask for the panel make and model, inverter, battery, mounting system and bird proofing. Reluctance to name components is a warning sign, and so is 'Tier 1 panels' without a model number.

DNO notification handled correctly

The installer should handle G98 notification, or G99 approval in advance where the inverter or battery capacity requires it. Battery export capacity is a common thing to get wrong.

Track record and aftercare

Look for a local, established firm with independently verifiable reviews, references from installs a few years old, a clear fault-response process, and monitoring set up in your name.

Their own installers

Ask whether the people on the roof are the company's own staff or subcontractors, and who signs off the electrical work (BS 7671 certificate, Part P notification and building control).

The most common mistakes

  • •Buying from a doorstep or high-pressure seller — 'today-only' discounts, finance pushed on the day, or claims the system will 'pay for itself in 5 years'.
  • •Taking a single quote. Get at least three itemised quotes so they can be compared like for like.
  • •Accepting an inflated savings forecast — unrealistic self-consumption, energy price inflation built into payback, and generation figures that ignore shading.
  • •Getting the system size wrong for how the house uses energy — not considering when power is actually used (who is home, EV, heat pump).
  • •Buying a battery that doesn't earn its keep — an expensive battery rarely pays back unless paired with a suitable time-of-use tariff.
  • •Ignoring roof condition and remaining life — panels may have to be removed and refitted later for roof repairs.
  • •Skipping the scaffolding and bird-proofing detail — frequent hidden extras; pigeons nesting under panels is a very common complaint.
  • •Not checking permissions — conservation areas, listed buildings and flats or leaseholds may need consent.
  • •Not getting the paperwork at handover — MCS certificate, electrical certificate, warranties, DNO confirmation, commissioning record and monitoring login. Without the MCS certificate there is no SEG.
  • •Not applying for SEG — many people never apply, or stay on a poor default export rate.
  • •Unclear finance or lease terms — finance must be FCA-regulated, and roof leases can make a property harder to sell or remortgage.

Find a trusted installer near you

Search for MCS-certified, RECC or HIES-member domestic solar installers within 10 miles of your postcode, with very high customer ratings.

Results are found via live web search and may be incomplete or out of date. Always verify any installer yourself on the official MCS register, the RECC directory and the HIES directory before appointing them.

Disclaimers

• This page is for domestic homeowners only. Commercial enquiries should use the main registration form.

• The calculator provides illustrative estimates only, based on UK average generation figures and the cost ranges in the attached 2026 guide. It is not a quotation or a guarantee of savings.

• Actual generation, savings and installed costs depend on your roof (orientation, pitch, shading and condition), your household energy use, your electricity tariff, and the specific installer and components you choose.

• Residential solar and qualifying battery installations currently attract 0% VAT; this relief is due to end on 31 March 2027, after which a 5% rate is expected to apply. Standalone battery retrofits may not always qualify — confirm VAT treatment with your installer.

• UEC Energy is not responsible for any decisions made based on these estimates. Always obtain at least three itemised quotes from MCS-certified, consumer-code-member installers before proceeding.
