What Is a Residents' Management Company (RMC)? A Plain-English Guide for Directors

The short answer

A Residents' Management Company (RMC) is a company owned by the leaseholders of a building, set up to manage that building. It is usually a private company limited by guarantee, registered at Companies House, with the leaseholders as its members and a handful of volunteer leaseholders serving as its directors. The RMC's authority comes from one of two places: the leases themselves (which name it as the party responsible for management) or ownership of the freehold.

If you have just been asked to "join the residents' management company" or have discovered your flat comes with a share in one, this guide explains what you have signed up for - in plain English, with the legal references where they matter.

How RMCs come to exist

1. Set up by the developer

In many modern developments, the developer creates the RMC at the outset and writes it into every lease as a third party. These are often called tripartite leases: the three parties are the freeholder, the leaseholder, and the RMC. The lease assigns the management obligations - repairing the structure, insuring the building, maintaining common parts, collecting service charges - directly to the RMC. Each purchaser automatically becomes a member when they buy their flat.

2. Created when leaseholders buy the freehold

When leaseholders club together to buy their building's freehold (known as collective enfranchisement), they normally form a company to hold it. That company - sometimes called a freehold management company or "share of freehold" company - functions as an RMC: it owns the building and manages it, and the leaseholders own it.

What an RMC is not

An RMC is frequently confused with two neighbouring structures, and the distinction matters because the legal rights and duties differ:

• RTM company - a company formed under the Commonhold and Leasehold Reform Act 2002 to take over management from the freeholder by statutory right, without buying the freehold. The qualification rules, formation process, and company articles are prescribed by statute. Our step-by-step Right to Manage guide covers the process in full.
• Residents' association (RTA) - a group of leaseholders that represents residents' interests but does not manage the building. A Recognised Tenants' Association has consultation and information rights under the Landlord and Tenant Act 1985, but no management powers. See our guide to leaseholders' associations.

Day to day, RMC and RTM directors do very similar work - the difference is where their authority comes from. Marklet's RMC overview page and RTM overview page set out how the same tools apply to each.

What the RMC is responsible for

The RMC's obligations come from the lease and from statute. In a typical block they include:

• Repair and maintenance of the structure, roof, common parts, and shared services - to the standard the lease requires, not just when something breaks.
• Buildings insurance - arranging cover for the whole building and, under the Leasehold and Freehold Reform Act 2024 reforms being phased in, providing greater transparency over commissions.
• Service charge administration - setting budgets, issuing demands, collecting payments, and accounting for the money. Service charges are subject to the Landlord and Tenant Act 1985: they must be reasonably incurred (Section 19), and leaseholders can challenge them at the First-tier Tribunal.
• Statutory consultation - under Section 20, works costing any leaseholder more than £250, or long-term agreements costing more than £100 a year, require formal consultation before the cost can be fully recovered.
• Holding service charge money on trust - under Section 42 of the Landlord and Tenant Act 1987, service charge funds belong to the leaseholders collectively and must be held in trust, ideally in a designated client account.
• Building safety - for buildings over 18 metres or seven storeys, the Building Safety Act 2022 adds "accountable person" duties; even below that threshold, fire risk assessments and routine compliance checks (lifts, electrical, asbestos, legionella) sit with whoever manages the block.

The RMC can do all of this itself ("self-managing") or appoint a professional managing agent to do it on the company's behalf. Either way, the legal responsibility stays with the RMC - an agent is the company's contractor, not its replacement. If your board employs an agent, our guide on holding your managing agent to account is a good companion to this one.

What RMC directors are personally signed up to

RMC directors are real company directors. The role is voluntary and almost always unpaid, but the duties in the Companies Act 2006 apply in full - acting within powers, promoting the success of the company, exercising independent judgment and reasonable care, and avoiding conflicts of interest. The company must also keep up its Companies House obligations: an annual confirmation statement, annual accounts (often dormant or micro-entity accounts for small RMCs), and an up-to-date register of directors and members.

In practice, the bigger day-to-day exposure is not company law but leasehold law: missed Section 20 consultations that cap recovery at £250 per leaseholder, service charge demands that are invalid because they omit the landlord's name and address (Sections 47-48, Landlord and Tenant Act 1987), or costs challenged at the Tribunal because no one can produce the paper trail. Most RMCs take out directors' and officers' (D&O) insurance precisely because volunteers should not carry that risk personally.

We cover the full list - with a practical annual calendar - in our companion piece, RMC director responsibilities: the complete checklist.

How an RMC actually runs

A well-run RMC tends to have a simple rhythm:

1. An annual general meeting where directors are appointed or re-elected, accounts are presented, and the year's budget and works are discussed.
2. A board that meets regularly - quarterly is common - with minutes, so decisions are recorded and survive director changes.
3. A service charge budget set before the year starts, tracked against actual spend, with variances explained rather than discovered at year end.
4. A single shared record of issues, contractor jobs, invoices, and correspondence - so the company's memory does not live in one director's inbox.

That last point is where most volunteer boards struggle. Email chains, spreadsheets, and WhatsApp groups work until a director moves away, an agent changes, or a leaseholder disputes a charge from three years ago. Our comparison of software, spreadsheets, and portals looks at the options for fixing this.

Common problems RMCs face

• Director burnout and succession - one volunteer does everything until they stop; nothing is documented; the next board starts from zero.
• Agent drift - the managing agent reports little, invoices arrive unitemised, and the board rubber-stamps because it lacks the records to push back.
• Arrears - a few non-paying leaseholders strain cash flow, and the company hesitates to enforce against neighbours.
• Compliance gaps - fire risk assessment actions, electrical condition reports, and lift inspections slip because no one owns the calendar.
• Disputes - service charge challenges at the First-tier Tribunal succeed against the RMC because consultation steps or paperwork were missed, not because the works were wrong.

None of these are character flaws - they are what happens when a volunteer-run company has professional-grade obligations and household-grade tools.

The bottom line

An RMC puts leaseholders in control of their building - and puts real legal duties on the volunteers who serve as its directors. The companies that run smoothly are not the ones with the most enthusiastic directors; they are the ones with the best records.
