Compare whole-of-market solar quotes (UK homes, June 2026)
The “best solar panel deal” in 2026 isn’t just the lowest headline price. It’s the best value system for your property: the right panel output, a suitable inverter, optional battery storage, strong warranties and a reputable MCS-certified installer—matched to your roof and your daytime electricity use.
It matters more this year. With the Ofgem price cap rising +13% to £1,862/yr from 1 July 2026 (confirmed by Ofgem on 27 May 2026), every kWh you generate and use at home avoids a higher import price, while surplus you export earns money via the Smart Export Guarantee (SEG). EnergyPlus compares whole-of-market home solar across the UK—solar-only or solar + battery.

What “best solar panel deals” means in 2026
In the UK, the best deal balances up-front price, expected generation, self-consumption (how much solar you use at home), export income (your SEG tariff), and installer quality. A low-cost system can underperform if panels are poorly positioned or the inverter is undersized; equally, premium kit is poor value if your roof or usage can’t take advantage of it.
1) Compare like-for-like system sizes
Request quotes for the same ballpark capacity (kWp). A “cheap” quote may simply be a smaller system. For many homes, 3–6kW is the common range depending on roof area and budget.
2) Match your battery to your export tariff
The best 2026 deals pair a battery with a high SEG rate (e.g. Octopus Intelligent Flux 32.17p/kWh). Check warranties on panels, inverter and battery, plus meaningful performance guarantees.
3) Prioritise reputable MCS installers
MCS certification is normally required to claim SEG export payments. Ask about accreditations, aftercare and how long the installer has been fitting domestic solar in the UK.
Typical solar panel costs in the UK (verified June 2026)
Pricing varies by roof complexity, access/scaffolding, system size, equipment brand, and whether you add battery storage. Use the guide below as a 2026 starting point—then get tailored quotes for your home. The 0% VAT on domestic solar and battery installations continues to apply in 2026, which is already reflected in installed prices.
| System type | Typical size | Typical home fit | Indicative installed range (UK, 2026) | Typical payback |
|---|---|---|---|---|
| Solar panels only | ~3–4kW | Smaller homes / limited roof | Often £4,500–£7,000 | ~7–9 years |
| Solar panels only | ~5–6kW | Typical family home | Often £6,000–£10,000 | ~7–10 years |
| Solar + battery | ~4–6kW + 5–10kWh | Maximise self-use & evening demand | Often £9,000–£15,000 | ~8–10 years |
| Solar + larger battery | ~6kW+ + 10–15kWh | High usage / EV / heat-pump home | Often £12,000–£20,000+ | ~9–12 years |
These figures are indicative for UK homes (June 2026) and can vary widely by property and specification. Payback ranges assume good self-consumption plus a competitive SEG export tariff; your quotes will reflect roof access, kit choice and installer availability in your area.
Best SEG export rates for solar (June 2026)
The Smart Export Guarantee (SEG) pays you for surplus solar you send to the grid. Rates vary widely by supplier and whether you have a battery—the top tariffs need a compatible battery and, in some cases, that you also buy your import energy from the same supplier. With the import cap rising on 1 July 2026, a strong export rate materially improves your returns. See our full SEG export tariff comparison for the latest detail.
| Export tariff | Export rate (p/kWh) | Type | Key condition |
|---|---|---|---|
| Octopus Intelligent Flux | up to 32.17p | Variable (smart) | Battery + Octopus import required |
| Octopus Flux | 29.32p | Variable (smart) | Battery + Octopus import |
| Good Energy Solar Savings Exclusive | 25p | Flat | Existing Good Energy customers |
| EDF Export Exclusive 12m V2 | 24p | Flat (12m fixed) | EDF import customers |
| British Gas Export & Earn Plus | 15.1p | Flat | Existing dual-fuel customers |
| Ecotricity | 8.9p | Flat | Open to most |
| Variable export floor (various) | 5–7p | Variable | Widely available baseline |
Savings and payback: what to expect in 2026
Your financial outcome comes from three places: (1) electricity you generate and use at home (avoiding imports at the rising cap rate), (2) electricity you store in a battery for the evening peak, and (3) surplus you export via SEG. Typical 2026 payback is 7–10 years, after which generation and export income are largely savings. The “best deal” is the system that aligns with your household’s pattern of use.
How homes maximise value
- Run washing/dishwasher in daylight (when safe and convenient)
- Use smart timers for immersion heaters (if suitable)
- Add a battery if most usage is evening-based, then pick a high SEG rate
- Check export eligibility and metering requirements for SEG (MCS usually required)
Factors that change payback
- Roof orientation and shading (generation potential)
- Your electricity tariff and the rising price cap (+13% from 1 July 2026)
- System size, battery size and component quality
- How much solar you self-consume vs export, and your SEG rate
Battery add-on economics: is it worth it in 2026?
A battery typically adds £3,000–£6,000 to a system depending on usable capacity (kWh). It earns its keep by raising self-consumption—storing midday solar for the evening peak you’d otherwise import at the capped ~24.7p/kWh (rising from 1 July 2026)—and by unlocking the highest SEG export tariffs, several of which (Octopus Intelligent Flux, Octopus Flux) require a battery. It can also let you charge cheaply on a time-of-use tariff and discharge at peak.
A battery usually pays off if…
- You’re out during the day and use most power in the evening
- You want access to top SEG export rates (e.g. 29–32p/kWh)
- You have or plan an EV or heat pump (higher, shiftable load)
- You value resilience and more control over rising import costs
Be cautious about over-spec if…
- You’re home in the day and already self-consume most generation
- Your evening/night usage is modest (a smaller battery may cycle more efficiently)
- The capacity you’re quoted rarely fully cycles—you pay for unused kWh
- Warranty cycle limits don’t match your expected daily use
Rule of thumb: size the battery to your typical evening/overnight usage, not the largest unit on offer. Always compare solar-only vs solar + battery quotes side by side to see the real incremental benefit.
Panels, inverters and batteries: what to compare
Installers may recommend different equipment mixes. Use these checks to compare quotes fairly and avoid paying more for features you won’t use.
Solar panels
- Wattage per panel and total system size (kWp)
- Efficiency and degradation/performance warranty
- Product warranty length and manufacturer reputation
- Aesthetics (all-black options) vs price
Inverter & monitoring
- String inverter vs microinverters (roof complexity/shading)
- Warranty and expected lifespan
- App monitoring and reporting features
- Battery compatibility (hybrid inverter if adding later)
Battery storage
- Usable capacity (kWh) and round-trip efficiency
- Power output (kW) for evening peak use
- Cycle warranty and warranty conditions
- Compatibility with top SEG export tariffs
A simple comparison checklist for quotes
- System size: total kWp and expected annual generation estimate (kWh).
- Kit: panel model, inverter model, battery model (if included).
- Warranties: panel product & performance, inverter, battery, workmanship.
- Export: MCS certification and which SEG tariffs the system qualifies for.
- Installation: scaffolding, DNO application, roof works, bird protection (if needed), timescale.
- Aftercare: monitoring support, call-out policy, who to contact for faults.
Is your home suitable for solar panels?
Many UK homes can benefit from solar, but suitability affects the deal you’ll receive. Installers will typically consider roof space, structure, shading and access. If you’re unsure, it’s still worth requesting quotes—installers can advise based on your property.
Usually a good fit
- South, east or west-facing roof areas
- Limited shading from trees or nearby buildings
- Sound roof condition with enough usable area
- Homeowners looking to cut electricity imports as the cap rises
May need extra checks
- Heavy shading at peak daylight hours
- Complex roofs (multiple elevations/dormers)
- Listed buildings or conservation areas (planning considerations)
- Older roofs that may need maintenance first
Planning rules can vary. Your installer should advise on whether your proposed installation is permitted development or needs permission, and will normally handle the DNO application for grid connection.
Common mistakes to avoid when chasing a “deal”
Solar is a long-term home upgrade. Avoid these common pitfalls to make sure the deal you choose stays a good deal years from now.
Comparing price only
Two quotes can differ due to system size, panel quality, inverter type, or included works. Compare specifications and expected generation, not just totals.
Ignoring shading and layout
A cheaper layout that underperforms can cost more over time. Ask for generation estimates and how shading is handled (optimisers or microinverters).
Overbuying battery capacity
Batteries improve value only if they match your evening demand. Compare solar-only vs solar + battery to see the real benefit before over-spec’ing.
Not checking aftercare
Ask who supports monitoring, faults and warranty claims. A strong installer will make this clear in writing.
Ignoring the SEG export tariff
Export rates range from a 5–7p floor to 32.17p on Octopus Intelligent Flux. The wrong tariff leaves real money on the table—check eligibility before you commit.
Rushing the decision
A good deal will stand up to comparison. Review at least two quotes and ask for written specs before proceeding.
FAQs: best solar panel deals for UK homes (June 2026)
Are solar panels worth it in the UK in 2026?
For many homeowners, yes—when the system is sized correctly and installed well. With the price cap rising +13% to £1,862/yr from 1 July 2026, every kWh you self-generate avoids a higher import price, and surplus earns SEG export income. Typical payback is 7–10 years, after which generation and export are largely savings.
How much does a solar system cost in 2026?
As a 2026 guide: ~3–4kW solar-only often £4,500–£7,000; ~5–6kW £6,000–£10,000; solar + battery £9,000–£15,000; larger systems £12,000–£20,000+. Domestic solar and battery installs continue to benefit from 0% VAT in 2026. Your quotes will reflect roof access, kit and installer availability.
What is the best SEG export rate right now?
As of June 2026, Octopus Intelligent Flux pays up to 32.17p/kWh (battery and Octopus import required), with Octopus Flux at 29.32p, Good Energy Solar Savings Exclusive at 25p, and EDF Export Exclusive 12m V2 at 24p. Variable floors sit around 5–7p. See our SEG export comparison.
Is a solar battery worth adding in 2026?
A battery (typically +£3,000–£6,000) raises self-consumption and unlocks the highest SEG tariffs, several of which require one. It’s usually worth it if you have higher evening usage, an EV or heat pump, or want more control as the cap rises—sized to your typical evening/overnight use rather than over-spec’d.
How does export offset the July 2026 cap rise?
The cap rises +13% to £1,862/yr on 1 July 2026, so imported electricity costs more. Solar reduces those imports, and surplus you export at 25–32p/kWh earns income—often £375–£800/yr depending on system size and tariff—which increasingly offsets the higher import cost.
Do I need MCS certification to get SEG payments?
In most cases, yes. SEG export tariffs are usually available only when the installation is completed by an MCS-certified installer (or an equivalent accepted scheme) and the system meets the supplier’s eligibility rules. Confirm eligibility with your chosen export provider before installation.
Will solar work on an east- or west-facing roof?
Yes—many UK homes with east/west aspects still see good results. You may generate more in the morning/afternoon rather than a single midday peak, which can suit household usage patterns and pair well with a battery.
How many quotes should I compare?
Aim for at least two or three quotes with comparable system sizes. When you request quotes via EnergyPlus, you can compare options side by side and focus on value, warranties, SEG eligibility and installer quality.
How long does installation take?
A typical domestic install is often completed in 1–2 days once scaffolding is in place, though the overall timeline can be longer due to survey, design and DNO permissions. Adding a battery may extend the install slightly.
What homeowners look for (and what they wish they’d known)
Every home is different, but the themes are consistent: clear specs, realistic generation estimates, the right SEG export tariff, and responsive aftercare. Here are typical sentiments we hear from UK homeowners comparing solar quotes in 2026.
“Comparing quotes properly made the difference. One ‘cheap’ option was smaller and had shorter warranties.”
Homeowner, South East England
“Adding a battery let us switch to a higher export tariff. With the cap going up this summer, it felt like the right call.”
Homeowner, West Midlands
“The installer’s aftercare and monitoring mattered more than I expected. It’s not just the panels.”
Homeowner, Scotland
