It’s more complicated than for a freehold house — but not always impossible. Here’s what to check.
This is the crucial question. In most flats and many leasehold properties the roof is not demised to the individual leaseholder — it belongs to the freeholder or is common parts managed by a management company. You will normally need their written consent.
Leases often contain clauses about alterations to the structure and exterior. Review yours, or ask your managing agent, before spending money on surveys.
Some blocks install a communal system serving landlord supply (lighting, lifts) or, less commonly, an arrangement shared between flats. This usually requires the freeholder or residents’ management company to lead.
Flats are more likely to sit in conservation areas or listed buildings, which adds another layer. Check with your local planning authority.
Consider a green electricity tariff and efficiency measures instead — a reputable installer will tell you honestly if your property isn’t suitable.
