Why bother with solar in 2026?

Electricity prices may move around, but the long-term trend has been upwards. A well-designed solar PV system can cover a large chunk of your daytime usage and, with a battery, push your grid imports right down – especially if you also have an EV or work from home.

  • • 0% VAT on qualifying domestic solar installations (subject to current rules).
  • • SEG can pay you for exports (rate depends on supplier/tariff).
  • • A well-designed solar PV system can reduce the amount of electricity you buy from the grid. Actual generation, self-consumption and bill savings vary depending on roof orientation, shading, system size, battery storage, tariff and household usage patterns.
  • • Solar can improve your EPC rating and make the property more attractive to buyers.

Where the savings come from

  • • Using your own solar instead of buying every unit from the grid.
  • • Charging a battery with solar (and sometimes cheap night-rate electric).
  • • Exporting excess via SEG so generation isn’t wasted.

When solar makes most sense

  • • You expect to be in the property for several years.
  • • You’re at home in the day, or have an EV / immersion to soak up energy.
  • • Your bills are already high and you want a long-term fix.

Typical solar & battery setups

Every roof and home is different, but these examples give you a feel for the kind of systems we regularly install. Final designs and prices are always based on a proper survey.

Examples are guide-only and depend on roof type, access, cable routes and kit choice.

Smaller homes / lower usage

Starter Solar

Ideal for flats, smaller terraces and households with modest daytime use.

  • • ~3–3.6 kWp (approx. 7–9 panels)
  • • High-efficiency mono panels
  • • App for tracking generation

Typical installed range (guide only):

From ~£4,500–£6,000

Quote depends on access, roof type, protection and cabling routes.

Most common

Family Solar + Battery

Suits typical 3–4 bedroom homes looking for a solid cut in grid imports.

  • • ~4.5–5.5 kWp solar (roof-space dependant)
  • • 5–10 kWh battery with app control
  • • SEG-ready with smart meter support
  • • Option to prioritise EV / hot water loads

Typical installed range (guide only):

~£7,500–£10,500

Balanced for upfront cost, bill reduction and sensible payback.

Higher usage / EV homes

Larger Solar + Battery

For bigger families, heavy usage or properties with multiple EVs / high electrical loads.

  • • ~6–8 kWp solar (where roof allows)
  • • 10–15+ kWh battery capacity
  • • Expandable where future usage grows
  • • Strong focus on board layout & future-proofing

Typical installed range (guide only):

From ~£10,000+

Often best where bills are already high or multiple EVs are in use.

Solar only, solar + battery or battery only?

There isn’t a single “right” answer – it depends on how you use energy, your budget and how long you’ll be in the property. We’ll talk you through the options, but as a rough guide:

Solar only

  • • Best when someone is home during the day.
  • • Lower upfront cost than PV + battery.
  • • SEG can still pay for exports.
  • • Battery can often be added later if designed for it.

Solar + battery

  • • Best overall match for most family homes.
  • • Stores daytime excess for evenings and early mornings.
  • • Works well with time-of-use tariffs and EV charging.
  • • Higher upfront cost but can shorten payback time where usage is high.

Battery only

  • • Sometimes suitable for homes on good off-peak tariffs.
  • • Charges cheap at night, discharges at peak time.
  • • Often used as an upgrade on older “solar-only” systems.
  • • We’ll always check economics before recommending battery-only setups.
