The Renter & Flat-Owner Bundle
The Complete Renter Starter Bundle
Everything a renter or flat owner needs to cut their energy bills, stay cool in summer, and start generating their own electricity — no roof, no rooftop installer, no landlord battles. Five components, honest prices, in the order you should buy them.

This bundle is built for renters and flat owners who want to take control of their energy bills without needing a landlord's signature on every decision. Every item is portable, reversible, and moves with you when you do. We've put them in the order that makes financial sense — buy step 1 first, add the others as budget allows.
Step 1 — Balcony solar kit (the only essential purchase)
EcoFlow STREAM Plug & Play Solar System
2 × 400W rigid panels + 800W STREAM microinverter · G99 approved · 10-year inverter warranty
Two 400W panels and the microinverter that converts their output into 230V household electricity — everything in one box. EcoFlow is an official partner in the UK plug-in solar rollout, the STREAM has UK grid approval, and the app monitoring is best in class. The 2×450W bundle (£649) suits smaller balconies; start here and expand later.
⚠️ Honest notes: the microinverter is shipping in ~1 month due to demand — order now to lock the sale price. EcoFlow direct is £100 cheaper than the identical Amazon listing, which is why the main button above is the better deal.
💡 Mounting: EcoFlow bracket bundles are mostly sold out right now. Buy the no-brackets version above and add EcoFlow's own brackets when they restock, or use generic adjustable mounts from Amazon (£30–£60, search "adjustable solar panel mounting brackets 400W"). Leaning panels against a south-facing wall at ~30° is a free temporary start.
⚡ The connection — the bit the adverts skip
Grid-connected systems must currently be connected by a qualified electrician — budget £150–£300 one-off. In July 2026 the government confirmed it's proceeding: the product specification is published and regulations are being laid before Parliament to allow certified kits to be plugged straight into a socket. Once those regulations are in force and compliant products reach the ENA register, self-install becomes the norm. Until then, the electrician route remains compliant. (Full detail here.)
G98 form: notify your network operator within 28 days of connecting. Free, simple, your electrician usually does it. Not planning permission — nobody inspects your balcony.
Step 2 — Portable power station
EcoFlow DELTA 2
1 kWh LFP battery · charges from STREAM panels or mains · powers appliances, laptops, AC units
This is the renter's answer to home battery storage — no electrician, no installation, fully portable when you move. Charge it overnight on cheap electricity, charge it from your STREAM panels during the day, and use that stored power at peak times instead of buying from the grid at 26p/kWh. Also your backup power for outages.
💡 EcoFlow ecosystem: the DELTA 2 connects natively to your STREAM system via the EcoFlow app — one dashboard shows solar generation, battery charge and real-time consumption. No separate app needed.
⚠️ Important: the battery legal position
The government's plug-in solar legalisation explicitly covers solar-only systems — plug-in batteries that discharge into your home circuits are excluded from the new rules and will continue to require professional connection. The DELTA 2 avoids this entirely because it's a standalone portable unit, not grid-connected. It powers appliances directly from its own outlets rather than feeding your home circuits — which is why it's the right battery choice for this bundle.
Step 3 — Portable AC (summer comfort)
No landlord permission needed, no installation, takes 10 minutes to set up. During a UK heatwave your solar panels generate their most electricity precisely when you most want the AC running — a genuinely good pairing. We've tracked stock daily during the July 2026 heatwave sellout. Two confirmed in stock right now:
See our full portable AC guide for BTU sizing help — choosing the right size for your room matters more than the brand.
Step 4 — Smart thermostat
A smart thermostat lets you schedule heating to run during your solar generation window — noon to 3pm rather than 6pm when you're drawing from the grid. Small behaviour change, meaningful saving over a full year. Both options below are renter-friendly: reversible installation, no structural changes.
⚠️ Renters: Radiator thermostats are the safest choice — they replace only the valve head, need no wiring or boiler access, and unscrew in seconds when you move. They give room-by-room control but don't fire the boiler themselves, so they work alongside your existing thermostat rather than replacing it. Scheduling and remote control are free; geofencing and open-window detection need tado° AI Assist at £3.99/month.
Step 5 — Energy monitor
The missing piece that makes everything else work harder. If you have a smart meter, a clip-on energy monitor shows your real-time consumption alongside the EcoFlow app's generation data — the complete picture. Most people who install one find at least one always-on appliance draining 50–150W they never knew about.
The honest total — all five components
Buy in stages — solar kit and electrician first, then add each piece as budget allows. Steps 2–5 are all optional but each makes the previous step work harder. The DELTA 2 and portable AC are the highest-impact additions after the core solar kit.
