Who runs the grid in Gillingham (Medway)
The distribution network operator (DNO) for Gillingham (Medway) is UK Power Networks, which runs the South East England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, UK Power Networks only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Adding a heat pump or an EV charger in Gillingham (Medway)
A heat pump in Gillingham (Medway)
A heat pump does most of its work from November to February. Over those four months, 12 panels in Gillingham (Medway) make about 1,110 kWh, against 3,150 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Gillingham (Medway)
A 12-panel roof in Gillingham (Medway) makes about 820 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Common questions about solar in Gillingham (Medway)
What does a solar panel system produce in Gillingham (Medway)?
Each kWp of panels in Gillingham (Medway) makes 1,047 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,660 kWh, from about 240 kWh in December up to 820 kWh in July.
How much are solar panels in Gillingham (Medway)?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Gillingham (Medway) before a battery. What Gillingham (Medway) changes is the return, about 6,660 kWh a year from that system, and your design call prices your actual roof.
Would a system in Gillingham (Medway) need approval from the network operator?
Gillingham (Medway) is on UK Power Networks' network (South East England licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator. Our G98 vs G99 guide explains both routes.
How much can I earn from exporting solar in Gillingham (Medway)?
With typical use and no battery, a 12-panel system in Gillingham (Medway) exports about 5,722 kWh a year. At 12p per kWh that is roughly £687; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Is solar worth it in Gillingham (Medway) in winter?
It works, but the year is lopsided. 68% of a Gillingham (Medway) roof's output lands between April and September; the four months from November to February give about 1,110 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.

Reading for Gillingham (Medway) homeowners
Sourced, dated and written by us. The same ground we cover on your free call.
Do solar panels work in winter? Yes, just less than summer
Panels run on light, not sunshine. Cloud turns them down, not off. What that means for an awkward roof.
Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Three phase and EV charging: what actually changes
Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
Read the guide →How an air source heat pump actually works
It moves heat rather than making it. The cycle, the efficiency numbers and the trade-offs.
Read the guide →Which tariffs are actually built for battery charging
A battery buys cheap and uses dear. The tariff decides how much that is worth.
Read the guide →How to check an MCS certificate is genuine, before the deposit leaves your account
A logo proves nothing. Certification is business specific, technology specific and checkable.
