Installation & the rules that apply

This is a multi-split. Same F-gas certified-installer requirement and sub-750 GWP refrigerant rule as a single split, applied across a bigger system. Because it touches multiple rooms and routes pipes through the structure, it more often triggers planning or prior-declaration steps, freeholder, landlord or condominium and shared-wall consent, and neighbour distance and noise rules. Heritage and historic-centre restrictions apply to the outdoor unit just as for a single split, but the single shared condenser is often easier to get approved than several separate units.
