Renting — what you can actually do about solar

Balcony solar is now legal — with one caveat

The UK legalised plug-in solar for the first time via BS 7671 Amendment 4, which came into force on 15 April 2026. You can now install an 800W AC (balcony or garden) system at a rented property — railing-mounted, floor-standing, or on an outbuilding — without planning permission, and your landlord cannot unreasonably refuse under the Renters' Rights Act 2025.

The practical caveat: a BSI product standard certifying specific kits for genuine DIY self-connection was still pending publication as of June 2026 (expected July 2026). Until it is published, the compliant route is installation by a Competent Person Scheme (CPS) registered electrician via a hardwired fused spur — add £250–£450 on top of kit cost. A G98 DNO notification is also required before connection; this is a 5-minute online form submitted to your regional DNO, and does not involve your landlord.

Practical rules to protect your deposit: use railing-clamp or floor-stand mounts only — no wall drilling. Notify your landlord in writing before installing. Check your tenancy agreement for 'external alterations' clauses.

What an 800W system actually generates

On a south-facing balcony or garden in central England, an 800W system generates approximately 550–800 kWh per year. At current electricity prices (~27p/kWh), that is a saving of around £170–£220/year on your electricity bill.

• South-east England (optimal): 650–785 kWh/year
• Central England: 600–680 kWh/year
• North England / Scotland: 450–550 kWh/year
• North-facing or heavily shaded: roughly half the above

Kit costs range from £300 (budget single 400W panel) to £1,200 (dual-panel with microinverter and mounting hardware). Add the electrician cost (£250–£450) until DIY-certified kits are available. At the south-facing, mid-range end, payback runs 3–6 years.

Note: plug-in solar currently has no route to Smart Export Guarantee export payments. All generation goes into the home's circuits; surplus is exported at zero rate. Size to consume most of what you generate.

How to approach your landlord about a full rooftop system

If you want a proper rooftop install, your landlord needs to agree. These are the arguments that tend to work:

• The 2030 EPC C deadline: All rental properties must reach EPC Band C by October 2030 or face fines up to £30,000. Solar is often the most cost-effective route for properties already at Band D. Frame it as helping them get ahead of a legal requirement — spending from October 2025 counts toward their £10,000 cost cap.
• Smart Export Guarantee income: Any surplus export goes to the landlord, not you. A system generating modest export earns 10–25p/kWh from suppliers like Good Energy or E.ON. It is a direct income stream for them during void periods.
• Renters' Rights Act 2025: Landlords cannot unreasonably refuse requests for minor, reversible improvements. This is the legal basis for plug-in solar requests; a refusal without documented reason creates a paper trail you can use if needed.

Always make any request in writing. If refused, ask for the specific reason in writing. Shelter and Citizens Advice both publish template letters for housing improvement requests that can be adapted.

Other options that don't require any roof access

Community energy: Community energy co-operatives let renters buy a financial share in a solar or wind project. The electricity flows to the grid; members receive a bill credit proportional to their share. Active UK share offers include the Big Solar Co-op and Community Energy Together (via Ethex). These are financial investments with risk — check FCA registration before committing. Note: Ripple Energy, formerly a leading platform, entered administration in July 2025 and should not be relied upon.

Smart tariffs — no solar required: Any renter who pays their own electricity bill directly (not utilities-included) can switch to a smart time-of-use tariff. Octopus Agile requires a SMETS2 smart meter (request one free from your supplier) and tracks wholesale prices every 30 minutes. Shifting flexible loads — dishwasher, washing machine, EV charging — to cheap overnight or midday slots can save £200–£440/year with no hardware beyond the meter. No solar panels needed.
