By agreement
Grouped by what governs the address rather than by how much is in it, because the document decides the dates, the notice, the condition standard and who has to be asked before anything happens.
Not sure which one you are on? Read the first page of the thing you signed. It will say.
A licence or a room-only agreement, in a house full of other people.
Lodgers, HMO rooms, student rooms
One room out of a house that stays occupied. The smallest job on this site and the one with the most other people in it — housemates using the kitchen, a hallway that cannot be blocked, and a landlord who may live there.
What it involves →One agreement over the whole address — jointly, or on your own.
Everyone signed the same document
A flatshare where one agreement covers everybody. Straightforward while the household moves together and genuinely awkward when one person leaves mid-term, which in this postcode happens constantly.
What it involves →A sole or couple tenancy, and a check-out
The standard rental move. The document sets the end date, the notice and the condition you have to hand the place back in — and the judgement is made on the empty room rather than the furnished one.
What it involves →A lease with a freeholder above it, or a freehold with a chain behind it.
A freeholder, an agent and the communal parts
A flat you own, in a building you share. Your title stops at your front door, and everything between it and the street belongs to somebody with an opinion about move days, insurance certificates and the paintwork.
What it involves →A completion, and a chain behind it
A house sale, where the document that matters is the contract and the hour that matters is set by solicitors. Nobody is asking permission here — you are simply waiting on money moving up a chain.
What it involves →Between two agreements, which is a scheduling fact rather than a failure.
Held while the paperwork catches up
Between one agreement and the next. Goods collected, inventoried at the property and held — which in a postcode where tenancies end on fixed dates and start on flexible ones is the ordinary answer rather than a contingency.
What it involves →Five things. The measured volume, taken with a tape. The access at both ends, which on the hill and in the Roehampton blocks means more than a floor number. How much packing you want. Whether anything is held. And what the building or the agreement requires by way of arranging.
That last one is why two identical flats in SW15 can quote differently. A managed block with permitted hours, a lift booking and an insurance certificate to send is more work than a terraced conversion with a residents' bay, and the quotation says so rather than absorbing it.
No price, rate card or transit time appears anywhere on this site, because none is knowable before a survey. Begin on the quote form, or read the questions page.
Both addresses, and what kind of agreement governs the one you are leaving. That second answer tells us most of what we need to know.
