Home electrification means moving a home’s car, heating and some of its energy supply onto electricity: an EV charger, a heat pump, solar panels with a battery, and smart controls tying them together. In North East Scotland the practical question is whether your supply, consumer unit and earthing can carry the extra load, and in what order to add each piece. This guide sets out what has already changed, what each technology asks of your electrics, and what is funded in Scotland as of October 2026.
We have kept to facts with a source and a date. Where something depends on future policy or prices, we say so rather than guess.

What electrification asks of your electrical system
Each new technology adds a large load or a new source of power. Before adding any of them, three things need checking.
- The incoming supply. Most homes have a single phase supply. Whether it can carry a charger and a heat pump together depends on the main fuse rating and your other loads. SSEN runs the electricity network across the north of Scotland, and connecting an EV charger, heat pump, solar or battery involves notifying or applying to them.
- The consumer unit. Each large load needs its own circuit and protective device, so a full or old board may need changing first. Our consumer unit upgrade in Aberdeenshire page covers when that is needed; the price is £550 to £950 + VAT, or £750 to £1,000 + VAT bundled with an EV charger.
- The earthing. Under A4:2026, an outdoor EV chargepoint on a PME supply needs protection against a broken PEN conductor, such as an earth electrode or an open PEN protective device. This is checked at survey.
Load management helps. Smart chargers can measure the whole house supply and slow down charging when other heavy loads are running, which can avoid a supply upgrade.
EV charging at home
A home charger is normally a 7.4kW smart unit on a single phase supply. Faster 22kW charging needs a three phase supply, which most homes do not have. Every charger we fit is smart, as the law requires, and solar ready, so it can charge from your own panels when you add them.
- Price with us: £900 to £1,300 + VAT for a standard install, with packages from £995 + VAT (Ohme Home Pro or TeltoCharge) and from £1,195 + VAT (Hypervolt Home 3 Pro or myenergi Zappi). Cable runs beyond 15 metres, consumer unit upgrades and earthing upgrades are quoted after the survey.
- Grant: the OZEV grant pays 75% of the cost, up to £500, for renters and flat owners with private off street parking. Most homeowners with a driveway cannot claim it.
For prices, packages and how the survey works, see our EV charger installation in Aberdeenshire page.
Vehicle to grid and vehicle to home
Bidirectional charging lets a car’s battery supply power back to the home or the network. A4:2026 now sets rules for it: protective devices must work with current flowing in either direction, and the system must disconnect from the network in a power cut (loss of mains protection to G98 or G99). Whether it is worth having depends on your car, the charger and your supplier, so check all three before paying extra for it.
Heat pumps
An air source heat pump replaces a boiler with an electrical appliance, usually on its own circuit from the consumer unit. Two facts frame the decision in Scotland.
- Funding: the Home Energy Scotland Grant and Loan, funded by the Scottish Government, offers homeowners up to £7,500 in grant for a heat pump, plus an optional interest free loan of up to £7,500. Rural and island homes can get an extra £1,500 uplift. Replacement heat pumps get the loan only.
- The Boiler Upgrade Scheme is not available here. Some guides quote its £7,500 grant, but gov.uk says the scheme is open to people in England and Wales.
On running costs, Ofgem’s cap for October to December 2026 puts electricity at 26.32p per kWh against 7.97p for gas, so electricity costs about 3.3 times as much per kWh. A heat pump’s running cost compared with a boiler therefore depends on how efficiently it runs in your home and on your tariff. Get a heat loss based design and figures for your house rather than relying on averages.
The electrical side is ours to check: a dedicated circuit, space on the board and enough supply capacity for the heat pump alongside everything else. The heat pump itself is designed and installed by a heating installer.
Solar panels and battery storage
Solar works in the North East, but plan with realistic numbers. Our guide figures are 1,800 to 2,800 kWh a year for a 3kWp to 4kWp system and 2,400 to 3,000 kWh a year for a 4kWp system, depending on orientation and shading.
| System | Installed price |
|---|---|
| 3kWp to 4kWp solar only | £7,000 to £8,500 |
| 4kWp solar with a 10kWh battery | £10,000 to £12,000 |
| 6kWp+ solar with a 10kWh+ battery | £12,000 to £15,000 |
| Battery added to existing solar (5kWh to 10kWh) | £3,500 to £5,000 |
0% VAT applied automatically on qualifying residential solar and battery installs until at least March 2027.
- Equipment: we fit SolarEdge, Fox ESS, Alpha ESS and SolaX inverters and batteries, with tier 1 monocrystalline panels carrying a 25 year performance warranty.
- MCS and export payments: every installation we complete is fully MCS registered through our Q-Smart partnership. Q-Smart is a Competent Person Scheme. Faithful Spark Electricians carries out the installation and Q-Smart issues the MCS certificate, so your system qualifies for the Smart Export Guarantee.
- Smart Export Guarantee: Ofgem’s scheme requires licensed SEG suppliers to pay for low carbon electricity you export. Each supplier sets its own rate and terms, and the rate must always be above zero, so compare offers. Our Smart Export Guarantee guide for Scotland explains how to register.
- Scottish funding: standard solar panels and home batteries are not on the current Home Energy Scotland Grant and Loan list. Only hybrid solar PV and water heating systems get loan funding.
- Backup power: a battery does not automatically keep the lights on in a power cut. That needs a battery and inverter with a backup function and the wiring to suit, so ask for it at design stage if it matters to you.
A4:2026 added requirements for stationary batteries in homes, so a battery installed now should be installed and certified to the current edition. For a quote, see our solar panel installation in Aberdeenshire page, or home battery storage in Aberdeen if you already have panels.
Smart controls that tie it together
The value of electrification comes from timing: charging the car and heating water when electricity is cheapest or when the panels are producing. Useful controls include:
- EV chargers that divert surplus solar into the car (all four units we fit can do this).
- Hybrid inverters that decide whether solar goes to the house, the battery or the grid.
- Heating controls and timers that run a heat pump or immersion heater in cheaper periods.
- Apps that show what each system is using, so you can see whether a tariff suits you.
Mixing brands is possible, but integration is simpler when the inverter, battery and charger are known to work together. Ask what talks to what before you buy.
A sensible order for most homes
- Test what you have. An EICR shows whether the existing wiring and earthing are sound before you add large loads.
- Check the supply and board. Confirm the main fuse rating, spare ways and earthing arrangement.
- Upgrade the board if needed, sized for the circuits you plan to add, not just today’s.
- Add the EV charger with load management if the supply is tight.
- Add solar, then a battery, or both together if the budget allows.
- Plan the heat pump with a heating installer, using the Home Energy Scotland funding route, and let your electrician confirm the supply can take it.
Your own order may differ. If the car comes first, the charger comes first; the point is to check capacity once and plan for what follows.
Frequently asked questions
Can my house supply run an EV charger and a heat pump at the same time?
Often yes, especially with a smart charger that uses load management to reduce charging while the heat pump runs. It depends on your main fuse rating and other loads, which are checked at survey. If the supply is not enough, a larger supply is an application to SSEN.
Is there a grant for a heat pump in Scotland?
Yes. The Home Energy Scotland Grant and Loan offers homeowners up to £7,500 in grant plus an optional interest free loan of up to £7,500, with an extra £1,500 for rural and island homes. The Boiler Upgrade Scheme covers England and Wales only.
Are solar panels worth it in North East Scotland?
They can be, but use realistic generation figures: 2,400 to 3,000 kWh a year is our guide for a 4kWp system. The return depends on how much you use yourself, your import tariff and the export rate your supplier offers.
Is there a grant for solar panels in Scotland?
Not for standard solar panels or batteries through Home Energy Scotland at present. What is available is 0% VAT on the installation until at least March 2027, and Smart Export Guarantee payments for exported power on an MCS certified system (ours are MCS certified via our Q-Smart partnership).
Do I need a three phase supply?
Most homes do not. A 7.4kW charger, a typical heat pump and solar all work on single phase. Three phase becomes relevant for 22kW charging or very large combined loads, and it is an application to SSEN.
Will a home battery keep my power on in a power cut?
Only if it is designed to. Backup needs an inverter and battery with a backup function and suitable wiring. Without it, the system shuts down when the grid goes off, as safety rules require.
