Solar panel installation in Lancashire costs from £5,999 fully installed — including battery storage, scaffolding and — when you use an MCS-registered installer like Alliant Energy. A correctly sized system covers 65–90% of a typical household's electricity use and earns additional income through the Smart Export Guarantee.
Key takeaways
Why now
The electricity bill shock of 2022–2023 never fully reversed. Under the Q3 2026 Ofgem energy price cap, the standard unit rate in the North West sits at approximately 25.2p/kWh — more than 50% above the pre-2022 norm of 16p/kWh. A typical Lancashire semi-detached home consuming 3,500 kWh per year now spends around £880 annually on electricity alone, even on a direct debit tariff.
Solar panels address this directly. A correctly sized system generates electricity from your own roof at an effective cost well under 5p/kWh over its 25-year life — and any surplus gets paid back to you via the Smart Export Guarantee. Add battery storage and the Levelise smart hub, and your system can also buy cheap overnight electricity and sell it back during peak price windows — turning your home's energy setup from a cost into an income stream.
Nationally, the trend is accelerating. More than 2 million UK homes now have solar panels, and MCS recorded a record 267,032 rooftop installations in 2025 — 31% above the previous record set during the original Feed-in Tariff era. In Lancashire, the Warm Homes Local Grant has further accelerated adoption by making fully-funded installations available to eligible households for the first time.

The package
Every Alliant residential installation uses the same core equipment stack, regardless of system size:
The equipment
Alliant Energy installs DMEGC 465W monocrystalline solar panels — a tier-1 manufacturer with a 30-year product warranty and independently verified performance degradation of less than 0.4% per year, meaning your panels still produce at least 88% of day-one output after 30 years. DMEGC panels use PERC cell technology (Passivated Emitter and Rear Cell), which increases efficiency by capturing reflected light from the rear of each cell.
Each panel is mounted using Clenergy tilt-frame racking rated to BS 6399-1 wind-load standards, with Fastensol flashings providing a watertight roof seal. The Fox ESS H3 hybrid inverter converts DC power from the panels to AC power for your home, manages grid export for Smart Export Guarantee payments, and communicates with the Levelise hub for real-time optimisation.
The process
Most Alliant residential installations complete within 4–8 weeks from signed contract to Permission to Operate (PTO).
MCS-registered engineer assesses roof orientation, pitch, shading (Aurora Solar) and energy consumption.
Itemised fixed price confirmed, finance options presented — no post-survey price changes.
Alliant submits G98 (up to 3.68kW) or G99 application on your behalf — typical processing 2–6 weeks.
DMEGC 465W panels, Fox ESS H3 inverter, battery and Levelise hub installed by MCS-registered in-house crews.
Full 18th Edition compliance test, commissioning checklist, inverter and battery configured.
Required for SEG export tariff application and confirmation with HMRC.
Register with an SEG supplier (e.g. Good Energy 25p/kWh). Levelise app configured. System live.
The most common source of delay is DNO processing. Electricity North West processes G98 notifications within 5–10 working days and G99 applications within up to 55 working days. Alliant submits both on your behalf — you don't need to contact the DNO directly. See what to expect from a solar installation.
Before any Alliant installation begins, we notify Electricity North West — the Distribution Network Operator (DNO) for Lancashire — under the G98 or G99 engineering recommendation, depending on system size. Systems up to 3.68kW (AC) export capacity use the simplified G98 notification. Larger systems require a G99 application with a review period of up to 55 working days. We submit both on your behalf.
All installations comply with BS 7671:2018 (18th Edition Wiring Regulations) and MCS MIS 3002. Post-installation, we issue your MCS certificate — required by HMRC to confirm eligibility and by your SEG supplier to approve your export tariff application.
Grants & incentives
Lancashire homeowners have access to several stacked incentives in 2026 that can substantially reduce — or entirely eliminate — the upfront cost.
The relief on residential solar PV and battery storage runs until 31 March 2027 under Schedule 7A of the Value Added Tax Act 1994 — saving £1,800 on a £9,000 system. For households in Lancashire whose Energy Performance Certificate (EPC) is rated D or below, the Lancashire County Council Warm Homes Local Grant — funded under the UK Government Warm Homes Plan — can reduce the cost of a solar + battery system to zero for eligible households. Qualification is means-tested, with income thresholds assessed by Lancashire County Council. Alliant Energy handles the eligibility assessment and grant application as part of project on-boarding — you do not need to navigate the Council portal yourself.
| Incentive | What it's worth | Who qualifies | Deadline |
|---|---|---|---|
| solar PV | ~£1,800 saving on a 12-panel package | All residential installations | 31 March 2027 |
| Warm Homes Local Grant | Free or heavily subsidised install | EPC D or below; means-tested income | While funds last |
| ECO4 | Free solar and battery | Qualifying low-income households | March 2026 (verify current status) |
| Warm Homes Plan loans | Up to £12,000+, 0% interest | Most Lancashire homeowners | Ongoing |
| 0% APR finance | Spread cost over agreed term | Subject to status (Phoenix Financial) | Ongoing |
VAT deadline: on residential solar runs until 31 March 2027. After that, the standard 20% rate applies — adding ~£1,800 to a £9,000 package. Our pipeline books 6–10 weeks ahead, so enquire before January 2027 to guarantee. Check your grant eligibility.
Smart Export Guarantee
The Smart Export Guarantee (SEG) pays you for surplus solar exported to the grid. Every MCS-registered Alliant install qualifies you to register. As of June 2026, the best available tariffs are:
| Supplier & tariff | Rate | Conditions |
|---|---|---|
| Good Energy Solar Savings Exclusive | 25p/kWh flat | No battery requirement |
| British Gas Export and Earn Plus | 15p/kWh flat | Existing British Gas customers |
| Octopus Intelligent Flux | Up to 32p/kWh (variable) | Requires battery + Octopus import tariff |
| Octopus Outgoing | 4.1p/kWh | No smart tariff required |
With the Levelise hub, your battery automatically exports stored energy during peak-price SEG windows — maximising earnings without manual intervention. Read more on whether battery storage is worth it.
How to pay
Three ways to fund a solar installation — and why ownership (via a solar loan or cash purchase) almost always beats a lease or PPA for Lancashire homeowners.
| Factor | Solar Loan | Solar Lease / PPA | Cash Purchase |
|---|---|---|---|
| Upfront cost | Low (deposit only) | Zero / minimal | Full system cost |
| Ownership | You own the system | Provider owns it | You own the system |
| SEG eligibility | Yes — you claim SEG | Provider claims SEG | Yes — you claim SEG |
| Savings | High — own all income | Lower — pay lease rate | Maximum long-term ROI |
| Yes | Varies by PPA structure | Yes | |
| Property sale | Adds value | Complications on transfer | Adds value |
| Best for | Can borrow, want ownership | Cannot fund any upfront cost | Maximum return, no debt |
A solar lease or Power Purchase Agreement (PPA) means a third party owns the panels on your roof — they claim the Smart Export Guarantee income and can complicate a future house sale. With Alliant's 0% APR finance or a Warm Homes Plan loan you own the system outright, keep all SEG earnings, and still benefit from Get a fixed-price quote.
Suitability
Most Lancashire homes are suitable. Here's what Alliant's engineers assess during the free survey.
| Factor | Optimal | Viable | May limit output |
|---|---|---|---|
| Roof orientation | South-facing | South-east or south-west (85–90% of peak) | North-facing only |
| Roof pitch | 30–40° | 15–55° | Below 10° or above 60° |
| Shading | No shading 9am–3pm | Partial morning/afternoon shade | Heavy all-day shading |
| Roof age | Under 15 years | 15–25 years | Over 25 years (assess first) |
| Roof type | Concrete or clay tile | Slate, flat roof, metal | Listed buildings (check planning) |
Nelson, Lancashire sits at 53.8°N and receives ~2.7 peak sun hours/day (PVGIS EU data) — an annual yield of ~860–920 kWh/kWp. Lower than southern England's 1,050 kWh/kWp, but still a compelling payback when import prices are 25p/kWh and rising. We use Aurora Solar satellite shading analysis at survey stage to quantify shading on your exact roof. See do solar panels work north of England?
For the Pendle Valley area — covering Nelson, Brierfield, Colne, and Barrowford — mean annual solar irradiance is approximately 985 kWh/m²/year (Global Horizontal Irradiance), sufficient for viable solar on any roof with at least 50% south-facing exposure. Alliant uses Aurora Solar's satellite shading analysis tool at survey stage to quantify the exact impact of any shading on your specific roof before a quote is issued.
Lancashire sits in the North West Energy Distribution Zone, served by Electricity North West Ltd. Under the Q3 2026 Ofgem energy price cap, the standard electricity unit rate in the North West is approximately 25.2p/kWh — elevated compared to pre-2022 rates of 16–18p/kWh. Lancashire County Council has committed to net-zero by 2030 and has allocated Warm Homes Local Grant funding specifically to Pendle District, Burnley Borough, and Ribble Valley.
Property value
A 2024 Swansea University study analysing over 1.5 million UK property transactions found solar panels increase property values by an average of 6.1–7.1% — a typical premium of £14,000–£16,000. The most direct mechanism is the EPC improvement: solar reliably pushes homes up the EPC scale, often from D to C or C to B, which affects mortgage eligibility, rental compliance and buyer appeal.
With minimum EPC C proposed for rental properties from 2030, solar panel installation in Lancashire is increasingly a long-term asset decision as well as an energy cost decision.

FAQs
In Lancashire, solar panel installation with battery storage typically costs £5,999–£9,000 for a 6–12 panel residential system in 2026, (valid until March 2027). Without battery storage, systems start from approximately £4,500–£6,500. Eligible Lancashire households may qualify for free or heavily subsidised installation under the Lancashire County Council Warm Homes Local Grant.
Yes. Lancashire receives approximately 2.7 peak sun hours per day on average (PVGIS data, 53.8°N). A 4kW system in Nelson or Burnley generates 3,200–3,500 kWh per year — sufficient to cover 65–90% of a typical household's electricity needs. The lower solar irradiance versus southern England is fully offset by identical import prices and the same grant eligibility.
From signed contract to Permission to Operate (PTO), Alliant typically completes residential installations in 4–8 weeks. The physical installation takes 1–2 days. Most of the lead time is DNO processing — Electricity North West processes G98 notifications within 5–10 working days, G99 applications within up to 55 working days. Alliant submits and tracks both on your behalf.
Alliant Energy's UK solar installation process follows these steps: 1) Free home survey — an engineer assesses roof orientation, pitch, shading (using shading analysis software) and your consumption profile. 2) Fixed quote issued within 1 working day — itemised pricing with no post-survey price hikes. 3) DNO notification — Alliant applies to Electricity North West under G98 (systems up to 3.68kW AC export) or G99 (larger systems, up to 55 working days review). 4) Installation — 1–2 days on site; DMEGC panels, Fox ESS H3 hybrid inverter, and battery installed to BS 7671:2018 (18th Edition Wiring Regulations) and MCS MIS 3002 standards. 5) Electrical test and commissioning — full 18th Edition compliance check, inverter and battery configuration. 6) MCS certificate issued — required by HMRC to confirm eligibility and by your SEG supplier to approve export tariff applications. 7) SEG registration — register with your chosen supplier (e.g. Good Energy at 25p/kWh) to begin earning export payments.
Several incentives are currently available in Lancashire: on all residential solar (valid until 31 March 2027, saving ~£1,800 on a £9,000 system); the Warm Homes Local Grant (free or subsidised installation for EPC D or below households, means-tested); ECO4 (free solar for qualifying low-income households); and Warm Homes Plan loans up to £12,000+ at 0% interest, available to most Lancashire homeowners.
The Smart Export Guarantee (SEG) is a UK government scheme requiring licensed electricity suppliers with over 150,000 domestic customers to pay solar panel owners for surplus electricity exported to the National Grid. Any MCS-registered solar installation qualifies. Rates range from 4.1p to 25p/kWh depending on tariff chosen, with variable tariffs via Octopus Intelligent Flux reaching 32p/kWh during peak export windows. The SEG replaced the Feed-in Tariff in January 2020.
The Smart Export Guarantee (SEG) pays you for surplus electricity your MCS-registered system exports to the grid. You register with an electricity supplier — rates currently range from 4.1p/kWh (Octopus Outgoing, no requirements) to 25p/kWh flat (Good Energy). With the Levelise hub, your battery exports during peak SEG windows, pushing effective rates higher. A 12-panel system with Levelise can earn £120–£220/year in SEG payments alone.
The Levelise Hub is a smart battery management controller developed for solar + battery storage systems. Installed alongside Fox ESS, GivEnergy, and compatible battery systems, it optimises charging and discharging across four revenue streams: self-consumption savings, Smart Export Guarantee income (timing exports to peak SEG windows), price arbitrage (buying grid electricity cheaply overnight, discharging at peak), and National Grid flexibility payments. Alliant Energy includes the Levelise Hub in all domestic solar packages. Customers operational for 36+ months average £440/year in combined Hub-driven savings and income above basic self-consumption.
A 2024 Swansea University study of over 1.5 million UK property transactions found solar adds an average 6.1–7.1% to property values. The primary mechanism is the EPC rating improvement — solar typically moves a property from EPC D to C or C to B, which improves mortgage eligibility and buyer appeal. With minimum EPC C proposed for rental properties by 2030, solar installation is increasingly a compliance decision as well as an energy cost decision.
Yes. Every Alliant Energy installation is carried out by MCS-registered installers — MCS (Microgeneration Certification Scheme) is the quality mark required for SEG payments and government grant funding. We also hold TrustMark Government Endorsed Quality, NICEIC, NAPIT, and RECC accreditations, and operate under ISO 9001, ISO 14001, and ISO 45001 management systems — independently audited annually.
The key checkpoints when comparing solar installers in Lancashire: MCS certification (required for SEG eligibility and Warm Homes Plan grants); TrustMark registration (required for government-funded installations); fixed pricing (post-survey price hikes are a common complaint in the sector); in-house crews (subcontracted installations are harder to warranty); and named equipment (if an installer won't name the panel brand, that's a red flag).
For most Lancashire homeowners in 2026, yes — battery storage significantly improves the economics. Without a battery, a typical system exports 40–50% of what it generates at 4–15p/kWh while buying back at 25p+ when the sun isn't shining. A 5.76kWh battery lifts self-consumption from ~35% to ~70%, cutting import costs substantially. With the Levelise hub, the battery also captures grid arbitrage income and National Grid flexibility payments. All Alliant packages include battery storage.
