Letting a leasehold flat: consents, restrictions and service charges

Owning the flat outright does not mean you can let it however you like. Most leases contain their own rules about subletting, and getting this wrong can mean breaching your lease rather than just annoying your freeholder. Here is what to check before you advertise the property.
Start with the lease, not the tenancy agreement
If you own a leasehold flat, the lease is a separate legal document from any tenancy agreement you go on to sign with an occupier, and it sits above it. The lease is the contract between you, as leaseholder, and the freeholder (or the management company acting for them), and it will almost always contain a clause covering subletting. Read it properly before you do anything else, ideally the actual clause rather than a summary someone gave you when you bought the flat, because the wording varies a lot between leases even in the same building.
Most leases fall into one of three categories: subletting is freely allowed, subletting is allowed but only with the freeholder's written consent (sometimes with a fee attached), or subletting is restricted in some other way, for example requiring the freeholder to be notified within a set number of days of a new letting starting. A smaller number of leases, often older ones, prohibit subletting altogether or only allow it for part of the property. If you are not sure how to interpret your lease, a solicitor who deals with leasehold property can usually confirm the position quickly.
Getting consent, and what it might cost
Where consent is required, do not treat it as a formality you can skip. Letting without the consent your lease requires is a breach, and while many freeholders will not chase a minor breach aggressively, some do, and it can create real problems if you later want to sell or remortgage, since a breach of lease has to be disclosed and can hold up a transaction. Apply in writing, keep a copy of the freeholder's written consent once you have it, and note any conditions attached to it, such as a requirement to register the tenancy or notify them of the occupier's details.
Some leases allow the freeholder to charge a registration fee or an administration fee for processing a subletting request. These fees are usually modest but should be budgeted for, particularly if you let the flat out again to a new occupier every year or two and the lease requires fresh notification each time.
Service charges, ground rent and how they interact with letting
As leaseholder you remain responsible for service charges and any ground rent regardless of whether the flat is let. Your occupier has no direct relationship with the freeholder or the building's managing agent, so if the service charge goes up, that is a cost you absorb or factor into the rent you charge, not something you can pass straight through to whoever is living there. It is worth building a buffer into your rental income calculations for service charge increases, since major works to a building, such as roof repairs or re-cladding, can be billed as a large one-off charge with relatively short notice.
Keep an eye on the building's reserve fund if the managing agent publishes accounts. A well-funded reserve fund reduces the chance of a sudden large bill landing on you mid-tenancy. If you are working out whether a leasehold flat still stacks up as an investment once service charges and ground rent are accounted for, it is worth running the numbers properly using a method like a standard rental yield calculation rather than just looking at the headline rent.
Insurance: who covers what
Buildings insurance for a leasehold flat is almost always arranged by the freeholder or the building's managing agent and paid for through the service charge. You should not need to arrange separate buildings cover, but you do need your own landlord contents and liability insurance for fixtures, fittings and anything you own within the flat, plus cover for loss of rent and landlord liability. Check what the building's buildings insurance actually covers, since some policies exclude certain types of damage or have excesses that are higher than you would expect, and make sure your own policy does not leave a gap.
The building's rules versus your tenancy agreement
Many leasehold buildings have additional rules around noise, pets, use of communal areas, and sometimes even restrictions on short-term or holiday letting. These rules bind you as leaseholder, and if you want them to bind whoever lives in the flat, you need to build them into your own tenancy agreement, because your occupier is not automatically bound by the lease, only by the terms you actually give them. If the building prohibits pets or has restrictions on noise after a certain time, say so clearly in the tenancy paperwork and during your inventory and check-in, which is also a good moment to document the condition of the flat properly before anyone moves in.
Be aware too that under the Renters' Rights Act, a general prohibition on keeping pets is no longer enforceable against a tenant in the way it might once have been, and tenants now have a right to request permission to keep a pet, which a landlord cannot unreasonably refuse. If your lease itself prohibits pets in the building, that restriction still applies and you should make clear to any prospective tenant that the building's rules, not your personal preference, are what is driving the position.
Managing agent versus building management
It is easy to conflate two different roles in a leasehold flat: the managing agent who runs the building on behalf of the freeholder, and your own letting or managing agent who deals with the tenancy itself. They are usually different companies with different responsibilities, and problems get resolved much faster when everyone involved knows which one to contact. If a communal repair is needed, such as a broken lift or an issue with the entry system, that goes to the building's managing agent, not your letting agent. If something inside the flat needs fixing, that is your responsibility as leaseholder and landlord, coordinated through whoever manages the tenancy for you.
A quick pre-letting checklist
- Read the subletting clause in your lease and confirm whether consent or notification is required.
- Apply for and keep written evidence of any required consent, noting any conditions or fees.
- Check what the building's buildings insurance covers, and arrange your own contents and liability cover to fill the gap.
- Factor service charges and ground rent into your rent calculations, with a buffer for likely increases.
- Carry over any relevant building rules, such as pet or noise restrictions, into your own tenancy agreement.
- Know who to contact for communal issues versus issues inside the flat itself.
The bottom line
Letting a leasehold flat is entirely routine, most flats in the UK are let this way without any drama, but it does add a layer of paperwork that a freehold house does not have. Sort out consent, understand your service charge exposure, and make sure your tenancy agreement reflects the building's own rules, and there is no reason a leasehold flat should be any harder to let successfully than any other property.
