SolaX Triple Power for a leasehold flat in London
Updated
In London, a leasehold flat is a consent problem before it is a SolaX Triple Power problem. If the cupboard is not inside the demise, or it sits on the escape route, this London job should stop.
SolaX Triple Power 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 SolaX Triple Power 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 SolaX Triple Power does not change that weather.
Money for SolaX Triple Power for a leasehold flat in London
Take a 5 kWh pack, cycled about 260 times, at 90% round trip. Charge at 7.0p, and value what comes back at 26.0p. Export given up is priced at 4.0p. There are no panels beside this 5 kWh pack, so every unit charged comes off the grid. Delivered energy is about 1170 kWh. After charging cost and lost export, the sketch saves about £213 a year. Set that against £4,161 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 19.5 years, which is past a typical 10-year warranty. 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 £4,161 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 SolaX Triple Power for a leasehold flat in London
In London, on UK Power Networks, 3.6 kW is in the band where G98 connect-and-notify is often enough. Export can still be capped. Agree that before the inverter is ordered. The sketch uses 5 kWh and 0 kWp, which is enough to tell two quotes apart if they assumed something else.
In London, the weak case for SolaX Triple Power is simple: Households whose priority is a widely recognised backup brand and a large certified-installer network.
Would I proceed with SolaX Triple Power for a leasehold flat in London?
I would not sign off a 5 kWh install from a video call. Someone has to open the consumer unit.
My default on SolaX Triple Power 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. £4,161 is a September 2026 illustration for a 5 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 5 kWh sketch the inverter is 3.6 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 £4,161 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the sketch changes. This page used 7.0p as a charge rate and 26.0p 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.
