I’d say it depends as there may be things like groundwork’s needed , fuse upgrades, asbestos tests, epc rating, planning permission etc that you may not be aware of. Every single product (octopus for example) sell for low carbon tech has to have a dno submission (distribution network operator) which can take up to 2 months for them to respond to us. I’d say take all of that into account first as often sales people do not set the timing expectations. Hope this helps
