Living aboard is legal, common and — done properly — straightforward. The complications almost always come from one thing: the difference between a mooring where people live and a mooring that is lawfully residential. This guide explains that distinction and everything that follows from it.
What is a residential mooring?
A residential mooring is a berth where a boat may lawfully be used as the occupant's permanent or main home. That status comes from planning permission held by the site operator, not from anything the boater does. It is generally not something an individual can apply for on a single berth.
Plenty of people live aboard at moorings without formal residential permission. That can breach both planning control and the mooring agreement, and the risk falls on the boater as well as the operator — enforcement action against the site can end with you needing to move at short notice.
Residential status is independent of the physical berth: a residential mooring can be a linear bank mooring, a pontoon berth or a basin berth. Types of moorings explained covers the physical formats, and this guide covers the legal status that sits on top of them.
Planning permission
Operators who allow residential use normally need planning permission from the local planning authority for that use. Interpretation and enforcement vary considerably between councils, and a site can hold consent for some berths and not others.
Before you sign anything, ask the operator directly:
Does this site have planning permission for residential use?
Does that permission cover the specific berth I am taking?
How many berths on the site are consented as residential?
Are there conditions attached — occupancy limits, seasonal restrictions, a cap on numbers?
Will you confirm the residential permission in the written agreement?
Get the answers in writing. If an operator will not put residential permission in the agreement, treat that as your answer. You can check who the planning authority is via GOV.UK's find your local council tool.
Council tax
If a boat is your sole or main residence, the mooring and boat may be treated as a dwelling and entered in the council tax list. Bands are assessed by the Valuation Office Agency, and the bill comes from the council for the area where the mooring sits. Liability normally falls on the occupier.
A mooring with no boat on it is generally exempt while it remains unoccupied, and the charge starts when a boat moves onto it. Councils differ in how they apply this, so ask both the operator and the billing authority rather than assuming.
Being asked to pay council tax is not a bad sign. It is usually evidence that the mooring is properly assessed as residential — which is what you want.
CRT and Environment Agency rules for liveaboards
On Canal & River Trust waterways, a boat without a home mooring must cruise continuously — no more than 14 days in one place on most of the network, less where signs say so, and on a genuine journey rather than back and forth along one stretch. A boat with a valid home mooring can stay at that mooring.
Many people live aboard as continuous cruisers. It is lawful, but it is not a residential mooring: you have no fixed berth, no security of location, and you carry the movement obligation year-round. CRT applies a surcharge to boats without a home mooring — 15% in 2026, rising to 25% by 2028.
The Environment Agency manages the non-tidal Thames, the Anglian waterways and the Medway Navigation. Registration is required for boats kept on those waters, but again it is separate from residential status — whether you may live aboard still depends on the marina's permission and the site's planning position.
What residential berths cost
It is widely assumed that a residential berth simply costs more. The Trust's own published vacancies do not bear that out. Its residential berths at Cuckoo Wharf in Birmingham work out at £159 to £177 per metre per year, below the £225 asked for leisure berths at Hockley Port a few miles away. Clarence Dock in Leeds sits at £230 per metre against £114 for a leisure berth at Dowley Gap, and Engineers Wharf in London is advertised at £8,979 a year for a 21.4m berth.
What makes a residential mooring expensive is that hardly any exist. Consent is held by the site, rarely granted, and cannot be applied for berth by berth — so in high-demand areas the berths that do come up are auctioned rather than sold at a fixed price. You are paying for scarcity and location, not a residential rate card. Add council tax, metered electricity and the higher day-to-day consumption of full-time living when you budget.
Residential consent is attached to a site, so supply is geographically lumpy. It is worth searching by location rather than by radius, and widening the search area well beyond where you would look for a leisure berth.
Utilities and daily life
Shore power: check the amperage, how it is metered and what it costs per unit — winter consumption on a liveaboard boat is substantial.
Water and waste: tap access on the berth, pump-out or Elsan on site, and refuse and recycling arrangements.
Heating: solid fuel, diesel or gas, and where you can store fuel safely on site.
Post: whether the site accepts post and parcels, and whether you can register the address.
Connectivity: fixed broadband is rare; most liveaboards rely on mobile data, so check coverage on the berth itself.
Parking and access: 24-hour access, a usable parking space, and how the site is reached in ice or flood.
Registering an address
Banks, employers, the electoral roll and the DVLA all expect an address. Sites with residential consent usually have a formal address structure for berths, which makes this straightforward. Sites without it often do not — one more practical reason the distinction matters.
Before you commit
Confirm residential planning consent in writing, for your specific berth.
Confirm the council tax position with the operator and the billing authority.
Check the notice period and what happens if the site loses or changes its consent.
Visit in winter as well as summer — access, heating and daylight all look different in January.
Speak to people already living on the site, out of earshot of the office.
Mooring contracts explained covers the clauses to read closely before signing.
