Covering Hampshire from a Hampshire base
Selenium Energy works right across Hampshire, not just in the city where we are based. Our office is in Winchester, but on any given week Steve is likely to be surveying a roof in Basingstoke, fitting a battery in Southampton, running an EICR in Portsmouth, or fitting an EV charger in Eastleigh. The county's road network: the M3 running north to Basingstoke and beyond, the M27 linking Southampton and Portsmouth along the coast, and the A34 and A303 serving Andover and the west: means most of Hampshire is a manageable drive from Winchester, and we plan our diary around that rather than pretending distance does not matter.
Travel time varies sensibly with distance: Southampton and Eastleigh are a short hop down the M3, Basingstoke and Andover a slightly longer run north and west, and Portsmouth further again along the M27 corridor. For most of the county a survey can be booked within a few days, and for jobs closer to Winchester - Alresford, Romsey, Twyford and the villages just outside the city - turnaround is often quicker still. We are upfront about this at enquiry stage rather than promising a response time we cannot stand behind.
Hampshire's housing stock changes a great deal from one town to the next, and we have fitted work across most of the variations the county throws up. Basingstoke's post-war new towns and modern estates sit at one end of the spectrum, with plasterboard construction, modern boards and generous roof space that usually make solar and EV charger installs straightforward. Southampton and Portsmouth mix dense Victorian terraces near the docks and city centres with 1930s suburbs and post-war estates further out, each with different loft access and supply arrangements. Market towns like Andover, Romsey and Alresford, and villages along the South Downs and towards the New Forest fringe, bring older cottages, listed buildings, rural single-phase supplies and, in places, conservation area constraints that need factoring into a quote from the outset.
The most common enquiries we get from across Hampshire are solar and battery quotes from homeowners comparing installers on price and honesty rather than sales pressure, EICR reports for landlords letting property in Southampton, Portsmouth and Basingstoke's rental-heavy areas, EV charger installs on suburban driveways from Eastleigh to Andover, and consumer unit upgrades on older housing stock in market towns and villages that has never had its board modernised. Wherever the job is in Hampshire, it is surveyed, quoted and fitted by the same person, with a fixed written quote typically within 48 hours of the visit.

What Hampshire properties actually need
The right specification for a Hampshire job depends heavily on where in the county the property sits: coastal city, inland market town or rural village all behave differently.
Property types and building age across the county
Hampshire's building stock spans a genuinely wide range. Basingstoke is largely defined by its post-war new-town expansion and more recent development, giving generous roof space, modern boards and straightforward access for solar and EV charger work. Southampton and Portsmouth mix dense Victorian and Edwardian terraces close to the docks and city centres with 1930s suburbs and post-war estates further out, so loft access and original wiring vary street by street even within the same city.
Market towns such as Andover, Romsey and Alresford, along with villages scattered across the South Downs and towards the New Forest fringe, bring a different challenge again: period cottages, some listed, timber-framed construction in places, and housing stock that has often had partial rather than full electrical upgrades over the decades. Eastleigh sits somewhere in between, with a strong mix of interwar semis and more recent infill development.
Roofs, orientation and Hampshire's varied climate
Hampshire runs from the chalk downland around Winchester and the South Downs to the flatter, more exposed coastal plain around Southampton and Portsmouth, and the wooded, sheltered fringe towards the New Forest: three quite different environments for a solar survey. Coastal properties around Portsmouth and Southampton Water get strong, relatively unshaded exposure but need equipment specified for salt-laden air and more exposed wind loading, while inland towns like Basingstoke and Andover tend to be more sheltered but can suffer more shading from mature street trees and hedgerows.
The South Downs and the chalk valleys around Winchester and Alresford create localised wind funnelling that we account for when siting panels and outdoor battery cupboards, and the New Forest fringe's wooded lanes mean shading from mature woodland is checked properly on site rather than assumed from satellite imagery.
Grid and infrastructure across the county
Supply arrangements vary considerably: Basingstoke's newer estates and much of Southampton and Portsmouth run modern three-phase or upgraded single-phase supplies, while rural properties around Romsey, Alresford and the New Forest fringe are sometimes still on older single-phase supplies that need a DNO application before higher-capacity solar, battery or EV charging work can go ahead. We identify this at survey stage so it is reflected in the quote and timeline rather than discovered later.
Off-street parking for EV chargers is generally straightforward on Basingstoke and Eastleigh's estate-style roads and on rural driveways, but denser terraced streets in Southampton and Portsmouth sometimes rely on on-street parking, which affects charger position and cable routing across a pavement.
- Modern three-phase and upgraded supplies common in Basingstoke and city estates
- Older rural single-phase supplies around Romsey, Alresford and the New Forest fringe
- DNO applications sometimes required before higher-capacity installs proceed
- Off-street parking availability varies significantly between estate roads and city terraces
- Coastal exposure near Southampton and Portsmouth affects equipment specification
Conservation areas, planning and rural access
Hampshire has a large number of conservation areas and listed buildings spread across its market towns and villages - Alresford, parts of Romsey and numerous South Downs villages among them - where solar panels, external cabling and equipment siting need extra care and, occasionally, planning consideration. City centre conservation areas in Winchester, Southampton and Portsmouth add similar constraints on a smaller number of properties.
Rural access brings its own practical points: narrow lanes towards the New Forest fringe and the Downs can restrict scaffold and delivery vehicle access compared with wide estate roads in Basingstoke or Eastleigh, and some rural properties have long cable runs between the supply, the consumer unit and the proposed panel or battery position that need planning into the quote from the start.

Hampshire questions, answered
Do you cover the whole of Hampshire?
Yes. We are based in Winchester and work right across the county, including Basingstoke, Southampton, Andover, Portsmouth, Eastleigh, Romsey and Alresford, plus villages along the South Downs and towards the New Forest fringe.
How quickly can you get to me in Hampshire?
It depends on distance from our Winchester base. Southampton and Eastleigh are a short run down the M3, Basingstoke and Andover a bit further north and west, and Portsmouth further again along the M27. Most surveys across the county can be booked within a few days.
How much does solar or battery installation cost in Hampshire?
Pricing depends on the roof and specification rather than the town, but recent installs across the county include £6,995 for 10 panels with a Fox EP6 5.76kWh battery and inverter, £8,500 for 13 panels with two Fox 5kW batteries, and £8,900 for 12 panels with a Sigenergy 10kW battery. Solar and battery installations carry 0% VAT, and the survey and quote are free.
Do you offer emergency call-outs across Hampshire?
Yes. Standard on-site hours are 7am to 6pm, Monday to Saturday, with emergency call-outs available outside those hours across the towns we cover for genuine faults such as total loss of power.
Are you accredited for this work?
Steve is NAPIT registered under Part P, RECC registered, OZEV authorised for EV chargers, and City & Guilds 2391 qualified for inspection and testing, with 25 years' experience as a qualified electrician. He is also MCS-qualified for solar PV and battery installation, with the company's own MCS accreditation currently in progress.
How long will an installation take, wherever I am in Hampshire?
Most domestic solar and battery installs are completed in a single day, and a standard EV charger install usually takes a few hours, regardless of which Hampshire town the property is in. Larger projects are scheduled and agreed with you in advance.
Is there VAT on solar and battery work?
Solar PV and battery storage installations currently carry 0% VAT anywhere in Hampshire. General electrical work, such as rewiring or consumer unit upgrades, is quoted individually and VAT is shown clearly on the quote.
I'm a landlord with property in Southampton or Portsmouth: can you carry out an EICR?
Yes. Our EICR inspections are carried out to City & Guilds 2391 standard anywhere in Hampshire, with a plain-English report and a talk-through of anything, if at all, that needs addressing before re-letting.
Can you fit an EV charger on a rural driveway near the New Forest or South Downs?
In most cases yes. Rural driveways are usually straightforward, though older single-phase supplies in some village locations occasionally need a DNO application first, which we identify and handle at survey stage.
Can you add a battery to solar panels I already have anywhere in Hampshire?
Yes, retrofitting battery storage to existing solar, including systems installed by other companies, is something we do regularly across the county. We check your existing inverter and consumer unit at survey and quote the most suitable route.
