Can't Get Solar Panels on Your Heritage Edinburgh Roof?

Plenty of Edinburgh homes can't take solar panels. A Category A listed townhouse in the New Town, a roof that faces straight onto the street, a tenement flat with a shared roof: the reasons vary, but the result is the same. Panels are off the table, or close to it.

That doesn't leave you without options. A solar battery works even without the solar. It charges when electricity is cheap and runs your home when it's expensive. There are no panels, no scaffolding and no change to the outside of the building. For many Edinburgh households, it's a practical way to take back control of their bills.

Quick take:

• A battery on its own can cut a typical Edinburgh electricity bill by around £260 to £330 a year on the right tariff.

• Higher-use homes can save £460 or more, and homes with an electric car can save more still.

• It shields you from price spikes and can keep the lights on in a power cut.

• In a typical home, bill savings alone won't repay a premium system within its warranty.

• Homes with an EV, a heat pump or high evening use get the most from it.

Why So Many Edinburgh Homes Can't Have Panels

Edinburgh's character is protected for good reason. The Old Town and New Town form a UNESCO World Heritage Site, and the city has around 50 conservation areas.

The rules did relax in May 2024. Scottish permitted development rights now cover solar panels in conservation areas, as long as they sit on a rear roof slope or a side slope that doesn't face a road. So if you live in a conservation area such as Stockbridge and your back roof suits panels, it may be simpler than you think.

A lot of homes are still left out:

• Listed buildings. Panels need listed building consent, and approval isn't guaranteed.

• The World Heritage Site. Homes in the Old Town and most of the New Town fall outside permitted development, so panels need planning permission.

• Street-facing roofs. In a conservation area, panels on the front of the house, or on a side that faces a road, still need permission.

• Tenement flats. The roof is usually shared, so the other owners have to agree by majority vote under the Tenements Act.

Add shading from taller neighbours and north-facing slopes, and a large share of the city simply can't make panels work.

How a Battery Saves Money Without Panels

Electricity prices now change through the day. On a time-of-use tariff, overnight power can cost around 15p per kWh or less, while the 4pm to 7pm peak can go well past 40p.

A battery makes use of that gap. It charges overnight at the cheap rate, then runs your home through the day and evening. You're still buying from the grid. You're just buying at a better time.

You'll need a smart meter that sends half-hourly readings. Most homes either have one already or can get one fitted free by their supplier.

Tariffs That Work With a Battery and No Panels

Not every tariff accepts battery-only homes. Octopus Flux, often recommended for batteries, requires solar panels, so it's out. These work instead (South Scotland rates, October 2026):

Agile carries more risk. Its 4pm to 7pm average was about 46.7p over the same period, and single half hours reached 87p. A battery that covers your evening handles that well. One that runs empty by 5pm doesn't.

If you drive electric, the Octopus EV tariffs deserve a close look. The cheap overnight rate covers the whole home, so your battery charges at it too.

What a Battery Could Save You

Here's an illustrative example. It assumes a Sigenergy battery with 8.76 kWh of usable storage, charging once a day, compared with staying on the October 2026 price cap (around 26p per kWh, with no VAT on electricity until 31 March 2027).

With an electric car on Intelligent Octopus Go, the home alone could save around £490 to £690 a year, before you count cheaper car charging.

These figures will move with prices, and your own pattern of use matters most. Your installer can model them against your smart meter data.

Be realistic about payback. A single-module Sigenergy system starts from around £8,000 installed. At £260 to £330 a year, a typical home won't recover that through bill savings within the battery's 10-year warranty. Homes with an electric car, a heat pump or heavy evening use come much closer, which is why they're the strongest fit.

Can You Sell Power Back to the Grid?

Sometimes, under the right conditions. The Smart Export Guarantee only pays for power from eligible generation such as solar panels, so a battery on its own doesn't qualify.

Octopus is the exception. Its Outgoing tariff accepts battery-only homes through a non-MCS route. It pays a flat 12p per kWh, or 16p between 4pm and 7pm on Prime Outgoing. You'll need:

• Octopus as your electricity supplier

• sign-off from SP Energy Networks, the local network operator

• an export meter number (MPAN)

• a £250 setup fee

The margin is thin. Buy at around 15p, lose a little in storage, sell at 12p to 16p, and there's not much left. Export works best for spare charge at peak times, not as your main source of savings. Octopus also runs occasional Saving Sessions that pay you to use less grid power at busy times, and a battery makes those easy to join.

More Than a Lower Bill

Savings are only part of what a battery gives you. It also puts you in control of when and how your home uses power.

• Protection from price spikes. Your battery covers the expensive hours, so you're less exposed when evening prices jump.

• Power during cuts. With the Sigen Energy Gateway fitted, selected circuits, or the whole home, can stay on through an outage. It's optional, so check what your system includes.

• No change to your building. The battery sits indoors or out of sight. Nothing goes on the roof or the front of the house.

• Ready for panels later. The Sigenergy controller is a hybrid inverter, so panels can connect if consent or circumstances change.

• Ready for an EV or heat pump. Both make a battery work harder, and an EV charger module can be added to a Sigenergy system later.

Why Sigenergy Suits Edinburgh Homes

When choosing a solar battery in Edinburgh without panels, the system has to fit the space you have and the tariff you're on. The installers we connect you with are Sigenergy-certified, supplied direct by Sigenergy's UK Platinum Distributor, and Octopus Energy Trusted Partners.

For most battery-only homes, a sensible starting point is:

• A 3.6 kW single-phase SigenStor Energy Controller. It stays within the limit for a simple G98 notification to SP Energy Networks, so there's no wait for approval.

• One SigenStor BAT 10.0 module. It holds 8.76 kWh you can actually use, and it can be fully discharged. At 3.6 kW it fills in about two and a half hours, which fits even the shortest cheap window.

Homes with an electric car or heat pump often suit a 5 to 6 kW controller with two modules (17.52 kWh usable). That needs a G99 application to SP Energy Networks, which can take several weeks.

Why it works well here:

• Room to grow. One controller takes up to six modules, about 54 kWh. Each module has its own optimiser, so new ones can sit alongside older ones.

• Fits awkward spaces. Each module measures 767 x 270 x 265 mm and carries an IP66 rating, so it can go indoors or outside.

• Runs itself. Sigen AI Mode uses your usage, the weather forecast and electricity prices to decide when to charge. The mySigen app shows you everything.

• Long cover. A 10-year manufacturer warranty, extendable to 15 years.

Where the Battery Goes, and What Consent You Need

Fire safety guidance (PAS 63100) says the best place for a home battery is outside. Indoors, it can't go in bedrooms, escape routes such as hallways and stairs, or lofts, and it needs interlinked smoke detection. In a New Town townhouse, that often means a basement, vault, rear area or mews building.

A battery inside the home doesn't normally need planning permission. Listed buildings are different. Fixings, cable runs or vents through historic fabric can need listed building consent, and an external unit on a visible wall in a conservation area may need council approval. Our accredited installers check this at survey, before you commit to anything.

A New Town Example

One of our customers lives in a Category A listed Georgian terrace in the New Town, inside the World Heritage Site. Roof panels there face the strictest consent rules, so he chose a battery instead.

We connected him with one of our accredited installers, who fitted a Sigenergy battery system indoors. There was no roof work and no change to the front of the building, and his home now buys more of its electricity at the cheapest times of day.

Costs and Support

• Price. Single-module Sigenergy installs start from around £8,000. Other brands' 10 kWh batteries start from around £5,500.

• 0% VAT. Standalone batteries are zero-rated for VAT until 31 March 2027, after which 5% is due to return.

• No grant for battery-only homes. Home Energy Scotland doesn't currently fund standalone batteries. Our solar incentives page covers schemes that may help if you add panels later.

Take Control, With or Without Panels

Not being able to fit panels doesn't mean missing out. A battery lets you choose when you buy electricity, protects you from the worst prices and keeps your home ready for what comes next. If you drive electric or use a lot of power, the savings are hard to ignore.

FAQs

Do I need solar panels to have a home battery?

No. A battery can charge from the grid at cheap rates and power your home when rates are high. You'll need a smart meter and a time-of-use tariff.

Can I get the Smart Export Guarantee with a battery only?

No. The Smart Export Guarantee pays for exports from eligible generation such as solar panels. Octopus's Outgoing tariff is the main exception for battery-only homes, with the conditions above.

Does a battery need planning permission in Edinburgh?

Usually not when it's fitted indoors. Listed buildings may need listed building consent for related works, and external units on visible walls in conservation areas may need council approval.

How big a battery do I need?

For most homes without an electric car, one 8.76 kWh module covers a typical day. Homes with an EV or heat pump often need two. Your installer will size it from your smart meter data.

Will a battery work in a power cut?

Only if the Sigen Energy Gateway is fitted and set up for backup. Ask which circuits your system covers.

Can I add panels later?

Yes. The Sigenergy controller can take panels if consent or circumstances change. Once you have panels, your exports would also qualify for the Smart Export Guarantee.
