Why solar makes sense in Hampshire

Hampshire market notes

Coastal salt-air exposure makes corrosion-rated mounting hardware important along the Solent. Inland, the standard A2 stainless mounting kits are fine. Installer lead times across Hampshire run 4-8 weeks outside peak season.

Typical property mix

A balanced mix of detached, semi-detached and terraced housing, with substantial new-build estates around Whiteley, Andover, Basingstoke and Eastleigh — many already pre-wired or configured for solar. Bungalows are common in coastal districts and ideal for solar.

Grants, VAT & export

0% VAT applies. The Smart Export Guarantee pays for export. ECO4 grants can cover most or all of an install for qualifying low-income households. Some New Forest and South Downs parish councils have small community-energy grant pools.

Solar panel costs and payback across Hampshire

The cost of solar panels in Hampshire in 2026 is driven by three things: the size of the array (kWp), whether you add battery storage, and how complex your roof access is. A typical 4 kWp system on a two-storey semi in Hampshire lands between £6,500 and £8,500 fully installed, MCS-certified and DNO-notified. Step up to a 6 kWp array with a 10 kWh battery — the fastest-growing spec across Hampshire — and most homes sit between £11,000 and £14,000. Larger 8-10 kWp systems for detached properties with an EV and a heat pump typically run £14,000-£18,000. Every quote from our vetted Hampshire installers is at 0% VAT under HMRC's Energy Saving Materials relief, which stays in place until at least March 2027.

Payback in Hampshire is amongst the fastest in the UK because the region enjoys stronger-than-average irradiance. Solar-only systems typically pay back in 7-9 years; solar plus battery in 8-11 years. Both numbers assume you self-consume 35-50% of what you generate (higher with a battery) and export the balance under the Smart Export Guarantee. Over a 25-year system life, most Hampshire households will see net savings of £18,000-£32,000 in today's money — closer to £45,000 once inflation on grid tariffs is factored in.

Battery storage and EV charging in Hampshire

More than three quarters of new solar installs across Hampshire in 2026 now include battery storage. The reason is simple: Hampshire homes generate the bulk of their solar during working hours, when nobody is home to use it. A 5-10 kWh battery captures that surplus and discharges it into the evening peak, lifting self-consumption from around 35% to 75-85%. Pair it with a time-of-use import tariff like Octopus Cosy or Intelligent Octopus Go and the battery also charges overnight at 7-9p/kWh, ready to power the morning peak. Popular batteries fitted across Hampshire include GivEnergy, Fox ESS, Tesla Powerwall 3 and Puredrive — every one carries a 10-year warranty and is IP65-rated for garage or utility-room installation.

A solar-aware EV charger completes the picture. Units like the Myenergi Zappi, Ohme ePod and Hypervolt Home 3 Pro monitor your solar export in real time and divert surplus power into the car — turning miles that would cost 8-10p/kWh on a smart tariff into free solar miles between April and September. Every EV charger installed by our Hampshire network qualifies for the OZEV EV chargepoint grant where you're eligible (flats and rental properties), and all are notified to your DNO on your behalf.

Roof types, planning and conservation areas in Hampshire

Hampshire covers a huge spread of housing stock — from Victorian and Edwardian terraces to 1930s semis, post-war estates, and brand-new developments with integrated in-roof panel options. Most Hampshire roofs sit between a 30° and 45° pitch, which is close to optimum for a UK south-facing array. East-west splits work well too: they flatten your daily generation curve, which pairs neatly with a battery and EV charger. Concrete tile, clay tile and natural slate all take standard MCS-compliant hook-and-rail mounting; flat roofs (typical of dormers and modern extensions in Hampshire) use ballasted A-frames that require no roof penetration.

Domestic solar in Hampshire is generally permitted development, meaning you do not need planning permission — but there are exceptions. Conservation areas, listed buildings, and flats always require consent, and in an Area of Outstanding Natural Beauty the panels must not project more than 200mm from the roof surface. Your installer will check your specific address against the local planning portal before quoting, and any required application (usually decided within 8 weeks) is priced into the quote at no extra cost to you.

DNOs, G98/G99 approval and export tariffs in Hampshire

Every solar install in Hampshire needs to be registered with the local Distribution Network Operator (DNO). Most of Hampshire sits under UK Power Networks or SSEN depending on the postcode, with a small number of fringe areas under National Grid Electricity Distribution. Systems up to 3.68 kW per phase are notified after commissioning under G98; anything larger — which includes almost every 4 kWp+ single-phase install — needs G99 pre-approval, typically decided in 4-8 weeks. Our vetted Hampshire installers handle every part of that submission, and won't quote you a system size the DNO won't approve.

Once commissioned, your system qualifies for the Smart Export Guarantee (SEG). You do not have to stay with your current import supplier to export — you can shop the SEG market independently. In 2026 the most popular tariffs amongst our Hampshire customers are Octopus Outgoing Fixed (15p/kWh flat), Octopus Flux (variable, peak export ~26p/kWh, designed for solar + battery households) and E.ON Next Export Exclusive (16.5p/kWh). See our Octopus Flux vs SEG tariff comparison for a full breakdown.

The install process and aftercare on every Hampshire job

From accepted quote to commissioned system, a standard Hampshire install runs 4-8 weeks. Your installer books scaffolding, submits the DNO paperwork, and files a Section 80 notification with your council (a free notification, not a planning application). Scaffolding typically goes up the day before install and stays for 5-7 working days. The on-roof work itself takes 1-2 days; battery, inverter commissioning and electrical certification (NICEIC or NAPIT) happen on day two. You'll receive your MCS certificate, Building Control notification (via the Competent Person scheme), electrical installation certificate and full product warranty pack within 5 working days of commissioning.

Every system installed via our Hampshire network is covered by a 25-year panel performance warranty (typically guaranteeing at least 84-87% output at year 25), a 10-12 year inverter warranty, a 10-year battery warranty, and a 12-year workmanship warranty backed by IWA insurance through RECC — so the workmanship cover survives even in the extremely unlikely event that your matched installer ceased trading. Annual remote monitoring and maintenance is included as standard, and any on-roof repairs during the workmanship period are handled at no cost to you.
