A typical 4kW solar panel installation costs between £4,999 and £5,499 fully fitted in the UK in 2026. Smaller 3kW systems start around £3,999; larger 6-10kW installs run £6,500-£9,500. Battery storage adds £3,500 (5kWh) to £10,000+ (15kWh). All prices include 0% VAT, panels, inverter, mounting, scaffolding and all paperwork.
Updated June 2026. These North East prices are typically £500-£1,500 cheaper than the UK averages quoted by national comparison sites — we explain why in the regional comparison below.
Here’s the full breakdown of what you actually get for the money and what drives the price.
Solar panel costs by system size
| Property | System size | Solar only | + 5kWh battery | + 10kWh battery |
|---|---|---|---|---|
| Flat / small terrace | 3kW (8 panels) | £3,999-£4,499 | £7,499-£9,499 | n/a |
| 2-3 bed semi | 4kW (10 panels) | £4,999-£5,499 | £8,499-£10,499 | £9,499-£11,999 |
| 3-4 bed detached | 6kW (15 panels) | £6,500-£7,500 | £10,000-£12,500 | £11,000-£14,000 |
| 4-5 bed detached | 8kW (20 panels) | £8,000-£9,200 | £11,500-£14,200 | £12,500-£15,700 |
| Large detached / multi-zone | 10kW+ (25+ panels) | £9,500-£14,000 | £13,000-£18,500 | £14,500-£21,500 |
These are full installation costs for a typical property in the UK in 2026. They include panels, hybrid inverter, mounting kit, all electrical work, scaffolding, DNO notification, MCS registration and SEG application — no hidden extras.
Solar panel cost in the North East vs UK average
National comparison sites publish “average” UK solar prices that aggregate quotes from large national installers, lead-aggregator referral pipelines and London/South-East-weighted samples. Our North East pricing typically undercuts those national averages by £500-£1,500 on a like-for-like spec, for three reasons: lower regional overheads, no lead-aggregator fee (national sites pay £80-£150 per lead they pass to installers, baked into the quote), and direct survey-to-install with no broker layer.
| System size | UK average (national comparison sites) | AMP North East (fully fitted) | You save |
|---|---|---|---|
| 4kW (10 panels) | £5,800-£6,500 | £4,999-£5,499 | £800-£1,000 |
| 6kW (15 panels) | £7,500-£8,500 | £6,500-£7,500 | £1,000 |
| 8kW (20 panels) | £9,500-£10,800 | £8,000-£9,200 | £1,500 |
| 10kW (25 panels) | £11,500-£13,500 | £9,500-£11,500 | £2,000 |

Solar panel costs over time
Looking at how solar pricing has evolved is useful context for anyone wondering whether to “wait a year for prices to drop further”:
| Year | 4kW install (UK average) | Notes |
|---|---|---|
| 2012 | ~£12,000 | Feed-in Tariff era, much higher panel prices |
| 2016 | ~£8,000 | Panel prices halved, FiT rates cut |
| 2020 | ~£6,500 | FiT replaced with SEG (January 2020) |
| 2023 | ~£5,500 | Energy crisis demand surge held prices |
| 2025 | ~£5,200 | Demand normalisation, panel prices flat |
| 2026 | ~£5,000-£5,500 | Largely stable, marginal further decline expected |
The big price drops are behind us. Solar panel manufacturing is now a mature commodity industry — there are no remaining 50% cost reductions to come. Year-on-year price changes have been within ±5% since 2020. If you’re considering solar and the economics make sense at current prices, waiting another year for “lower prices” is a bet on a small change.
What’s continued to improve is panel efficiency. Panels installed in 2026 are ~25% more efficient per square metre than 2018-era panels. That means you can fit more kW on the same roof, or hit the same kW with fewer panels.
What you get for £4,999 vs £6,500
The price difference between an entry-level and a premium 4kW install in 2026 is roughly £1,500. What you get for that extra:
Entry-level (~£4,999):
- Tier-1 panels (JA Solar, Trina, Jinko or Longi)
- Standard string inverter (Solis or similar)
- Standard mounting kit
- Standard 10-year workmanship + 25-year panel performance warranty
Premium (~£6,500):
- Premium panels (REC, LG, SunPower) with higher efficiency
- SolarEdge or Enphase microinverter system (panel-level optimisation, useful for shaded roofs)
- Premium mounting with corrosion-resistant fixings
- Same warranty period but more responsive support network
For most North East roofs with reasonable orientation and minimal shading, the entry-level install delivers virtually identical generation to the premium install. The premium option is genuinely worth it when:
- Your roof has chimney, vent or tree shading affecting some panels
- You’re installing on an east-west split (both aspects, no south)
- Roof access is awkward and replacement/maintenance would be expensive
- You value the better-known brand for resale value
We quote both options if your roof is borderline; for most installs the entry-level package is the right answer economically.
Battery storage cost
Battery prices vary dramatically by brand and chemistry. Current pricing:
| Battery | Capacity | Typical fitted price | Notes |
|---|---|---|---|
| AC | 5kWh | £3,500-£5,000 | Modular, retrofit-friendly |
| AC | 10kWh | £4,500-£6,500 | Most popular size |
| AC | 15kWh+ | £6,000-£8,500 | Larger homes or heat pump |
| Tesla Powerwall | 13.5kWh | £8,500-£10,500 | Premium, Tesla Energy Plan eligible |
| SolarEdge Home Battery | 10kWh | £5,500-£7,500 | DC-coupled with SolarEdge inverter |
| Solis hybrid + Pylontech | 5-15kWh | £4,000-£7,500 | Mid-range value option |
Battery payback runs 6-9 years standalone (on a smart tariff arbitrage basis) or 5-7 years when paired with solar. Modern LFP batteries are rated for 6,000-10,000 charge cycles — equivalent to 15-25 years of daily use. Manufacturer warranties typically cover 10 years.
What the cost gets you in savings
Worked example for a typical 3-bed semi in the North East with a 4kW solar install and 10kWh battery (total install: ~£10,500):
Year 1 financial benefit:
- Bill savings from self-consumption (70-80% of 3,500 kWh): ~£700-£800
- SEG export income (1,000-1,200 kWh at 15p): ~£150-£180
- Total Year 1: £850-£980
25-year benefit:
- Bill savings rising with electricity inflation: ~£24,000-£32,000
- SEG income (degrading slightly with battery wear): ~£3,500-£5,000
- Total 25-year: £27,500-£37,000
Payback on the £10,500 install: 8-9 years for the combined package, with the panels then continuing to generate for another 16-17 years of near-zero marginal-cost electricity.
Without a battery, the same 4kW install at £5,000 typically pays back in 7-8 years and delivers £18,000-£25,000 over 25 years. Adding the battery improves total returns at the cost of slightly longer payback.
What’s not included
A few costs that you should budget for separately if applicable:
- Bird/squirrel protection mesh: £150-£300, recommended for properties near trees or known wildlife issues
- Optimisers for shaded panels: £40-£60 per panel where partial shading affects performance
- EV charger installation: From £799 — pairs well with solar but separate quote
- Consumer unit upgrade: Rare, £300-£600 if your existing board can’t handle the inverter circuit
- Roof repair or strengthening: Some older roofs need structural work before mounting
- Listed building consent application: Rare, £200-£500 plus 4-8 week timeline
We flag any of these during the survey and quote them transparently before signing.
Solar panel cost vs heat pump cost
A useful comparison if you’re considering both:
| Service | Capital cost (typical 3-bed) | After grants | Year 1 saving |
|---|---|---|---|
| Solar + 10kWh battery | £10,500 | £10,500 (no grant) | £850-£980 |
| Heat pump (gas swap) | £12,500 | £5,000 (£7,500 BUS) | £50-£150 |
| Heat pump (oil swap) | £12,500 | £5,000 (£7,500 BUS) | £1,000-£1,500 |
| Solar + battery + heat pump | £23,000 | £15,500 | £1,300-£2,400 |
For most North East homeowners on mains gas, solar payback is faster than heat pump payback even after the BUS grant — because Year 1 savings are larger on solar. Heat pumps make economic sense fastest when replacing oil/LPG, or when the home was going to need a boiler replacement anyway.
For homes installing both, the combined install costs less than two sequential installs (shared scaffolding, electrical work, project management) and the solar dramatically reduces heat pump running costs by powering it from your own roof.
Frequently asked questions about 2026 solar panel costs
Are solar panels cheaper in 2026 than 2025? Marginally — typical 4kW prices have moved from ~£5,200 in 2025 to ~£5,000-£5,500 in 2026. Panel manufacturing is now a mature commodity industry and year-on-year changes have been within ±5% since 2020. Waiting another year for a meaningful price drop is unlikely to pay off.
Why is my quote higher than the UK average? Common reasons: a complex or multi-aspect roof, scaffolding access issues, a premium inverter (SolarEdge or Enphase), bird-mesh, an older consumer unit needing upgrade, or a listed/conservation property. Roof complexity is the single biggest swing.
Is there VAT on solar panels in 2026? No. Residential solar, batteries (including standalone retrofit batteries) and heat pumps are all zero-rated for VAT until 31 March 2027. The £4,999-£14,000 prices quoted here are inclusive of 0% VAT.
What’s included in a £4,999 4kW install? 10× tier-1 panels (~400W each), a 5kW hybrid inverter, K2 or Schletter mounting, all electrical work, scaffolding, DNO notification, MCS registration, SEG paperwork, a 10-year workmanship warranty and a 25-year panel performance warranty.
How much extra is a battery on top of solar? £4,500-£6,500 for a 10kWh battery added during the same install. 5kWh batteries add £3,500-£5,000; 15kWh+ £6,000-£8,500. Adding the battery at the same time as solar is ~£500-£800 cheaper than retrofitting later.
Are solar panel prices the same in the North East? No — our North East prices are typically £500-£1,500 cheaper than UK averages quoted on national comparison sites. Recent examples: NE8 4kW £4,999, SR4 6kW £6,800, DH1 8kW £8,400 — all fully fitted.
What pushes the price up? Roof complexity (hips, valleys, multiple aspects), 3-storey scaffolding, premium SolarEdge/Enphase optimisers, larger or modular batteries, bird/squirrel protection mesh, a consumer-unit upgrade, listed building consent, or installing on slate/stone-tile roofs.
Are there grants to reduce the cost? Solar PV itself has no UK grant in 2026. What’s available: 0% VAT on installation, the Smart Export Guarantee for exported power (typically 15p/kWh), and ECO4 / Great British Insulation Scheme for low-income households. To estimate your numbers with current prices, use the solar payback calculator. For grant detail across solar, batteries and heat pumps, see the grants page.
