Maintenance Responsibilities in London Shared Ownership Properties

Shared ownership is one of the most common routes to property ownership for first-time buyers in London, but the division of maintenance responsibilities between the shared owner and the housing association can be a source of significant confusion. This guide explains who is responsible for different types of maintenance in a London shared ownership home.
What Is Shared Ownership and How Does It Affect Maintenance?
Shared ownership is a government-backed scheme under which a buyer purchases a share of a property, typically between 25 and 75 percent of the full market value, and pays rent to a housing association on the remaining share. The buyer takes a long lease on the property, usually 99 or 125 years, and has the right to purchase additional shares over time in a process known as staircasing. Despite owning only a partial share of the property, the shared owner holds the leasehold interest and assumes full responsibility for internal maintenance and repair from the date of completion.
This means that a London shared owner who purchases a 40 percent share of a new-build flat is fully responsible for maintaining and repairing the boiler, plumbing, internal electrical installation, and all internal fixtures and fittings from day one, even though they own less than half of the property. The housing association as freeholder remains responsible for the structure of the building, the external envelope, and the common parts, with costs recovered through service charges payable by the shared owner.
The Shared Owner Responsibility for Boilers and Heating Systems
A London shared owner is responsible for maintaining, servicing, and replacing the boiler and internal heating system in their property from the date of their lease. Housing associations do not cover boiler breakdowns or boiler replacement costs for shared owners under normal circumstances. The shared owner should arrange an annual boiler service with a Gas Safe registered engineer and should budget for eventual boiler replacement, which in a London property will typically cost between 2,000 and 4,000 pounds installed depending on the boiler specification and the complexity of the installation.
Some London housing associations offered a boiler insurance or boiler repair plan to shared owners as an optional extra at the time of purchase. Shared owners who took up such a plan should check the terms carefully, as cover may be limited to repair rather than replacement, and there may be excesses, exclusions, and conditions that affect whether a claim will be accepted. If the shared owner does not have a boiler repair plan in place, they are responsible for the full cost of any boiler repair or replacement.
Service Charges and the Housing Association Responsibilities
The housing association as freeholder of the shared ownership block is responsible for the structure and common parts of the building, including the roof, external walls, communal heating and hot water systems in blocks where these are provided, lifts, and communal areas. The cost of maintaining and repairing these elements is recovered through service charges, which the shared owner pays regardless of their ownership share. Service charge demands in London shared ownership blocks can be substantial, particularly in new-build developments where the service charge includes the cost of managing a sinking fund for future major works.
Shared owners who dispute service charge demands have the same rights as any other leaseholder to challenge the reasonableness of service charges at the First-tier Tribunal. This right applies regardless of the proportion of the property owned. Shared owners in London blocks who receive unexpected service charge demands for major works such as communal boiler replacement, roof replacement, or lift refurbishment should seek independent legal advice before paying.
Gas Safety Certificates in Shared Ownership Properties
Where a shared ownership property is fully occupied by the shared owner themselves, the annual gas safety check is not a legal requirement in the same way it is for a landlord with a tenant. However, many London housing association leases require shared owners to maintain all gas appliances in safe working order and to provide evidence of annual servicing on request. Shared owners who sublet their property, which is usually permitted with the housing association consent, become landlords and must comply with all landlord gas safety obligations, including obtaining an annual Gas Safety Record.
Prestige Engineers carry out gas safety checks, boiler services, and boiler replacements for London shared ownership properties, providing Gas Safety Records and service certificates that meet housing association requirements. We can also advise on whether a gas appliance issue is the responsibility of the shared owner or the housing association, based on the terms of the specific lease.
