Huawei LUNA2000 for a leasehold flat in London
Updated
In London, a leasehold flat is a consent problem before it is a Huawei LUNA2000 problem. If the cupboard is not inside the demise, or it sits on the escape route, this London job should stop.
Huawei LUNA2000 on a leasehold flat in London
A side-return garage in Walthamstow and a mansion-block cupboard in Marylebone are not the same quote, and the paperwork should say which one was priced, which is the constraint I would write next to Huawei LUNA2000 for this leasehold flat.
UK Power Networks covers this London example. A 4 kWp-class roof at 980 kWh per kilowatt is about 2,940 kWh a year before shade, and Huawei LUNA2000 does not change that weather.
Money for Huawei LUNA2000 for a leasehold flat in London
Take an 8 kWh pack, cycled about 300 times, at 90% round trip. Charge at 9.0p, and value what comes back at 28.4p. Export given up is priced at 8.0p. About 857 kWh a year of the charge is treated as spare solar from 2.5 kWp that might otherwise have been exported. Delivered energy is about 2160 kWh. After charging cost and lost export, the sketch saves about £420 a year. Set that against £6,418 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 15.3 years on these assumptions. Nudge the night rate up by 4p and see if you still like it.
Where the job is a qualifying install in a home, the 0% rate runs to 31 March 2027 and is due to become 5% after that. This sketch prices the work at £6,418 on that basis. It does not apply to a shop, and it does not apply to a battery you buy and fit yourself.
Connection for Huawei LUNA2000 for a leasehold flat in London
In London, on UK Power Networks, 5 kW sits above the 3.68 kW G98 line, so this wants a G99 application before anyone energises it. Export can still be capped. Agree that before the inverter is ordered. The sketch uses 8 kWh and 2.5 kWp, which is enough to tell two quotes apart if they assumed something else.
In London, the weak case for Huawei LUNA2000 is simple: Retrofits that were supposed to leave a working SolarEdge or SMA inverter untouched.
Would I proceed with Huawei LUNA2000 for a leasehold flat in London?
I would not sign off a 8 kWh install from a video call. Someone has to open the consumer unit.
My default on Huawei LUNA2000 for a leasehold flat in London is no, unless written consent or a live warranty counterparty is already in the file.
Common questions
Is the price on this page a quote?
No. £6,418 is a September 2026 illustration for a 8 kWh example at the temporary 0% residential rate. Your survey replaces it.
Will it stay on in a power cut?
Only if a gateway or essential-load board was designed and paid for. A standard grid-tied battery turns off with the grid. On this 8 kWh sketch the inverter is 5 kW, and backup is still a separate line.
What paperwork should I keep?
Keep the MCS certificate where the job is certified, the electrical certificate, the DNO record, the schematic, the warranty registration and a photo of the schedule. For an illustrated £6,418 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the sketch changes. This page used 9.0p as a charge rate and 28.4p as the rate avoided. A smaller gap means a worse payback. Read the live tariff.

The figures above are a rough guide. An installer still needs to see your fuse board, where the battery will go, and whether you want power during a blackout.
