The short answer
A block management company is the organisation responsible for maintaining and administering the shared parts of a residential building, typically a block of flats. If you own or are considering buying a leasehold flat in London, understanding how block management works can save you thousands and prevent future headaches.
A block management company is the organisation responsible for maintaining and administering the shared parts of a residential building, typically a block of flats. If you own or are considering buying a leasehold flat in London, understanding how block management works can save you thousands and prevent future headaches. Our team works with leaseholders across the capital every day, and we've seen first-hand how the quality of block management directly affects property values, service charge bills, and day-to-day living.
What Does a Block Management Company Actually Do?
A block management company acts on behalf of the freeholder or Right to Manage company to keep the building running smoothly. Their duties typically include arranging building insurance, maintaining communal areas like hallways and gardens, organising repairs to the roof and exterior, and collecting service charges from leaseholders.
They also handle administrative tasks such as issuing Section 20 consultation notices for major works, enforcing lease terms, and liaising with contractors. In buildings with a concierge or porter, the block management company will manage those staff too. The quality of this service varies enormously across London, which is why savvy buyers always check the managing agent before committing to a purchase.
Service Charges and What You'll Actually Pay
Service charges are the annual fees leaseholders pay to cover the cost of running the building. According to HomeOwners Alliance, London leaseholders pay an average of £1,800 per year, though this can range from a few hundred pounds for a small conversion to over £10,000 in a luxury development with a gym and concierge.
Your block management company prepares the annual budget and invoices leaseholders, usually quarterly or half-yearly. Always request at least three years of audited service charge accounts before you buy. Look for unexplained increases, large sinking fund deficits, or outstanding Section 20 works that could land you with a hefty bill. Our /property-management team reviews these documents regularly and knows the red flags to watch for.
Right to Manage and Changing Your Block Management Company
If you're unhappy with your current block management company, leaseholders have the legal right to take over management through a Right to Manage (RTM) company. This requires at least half the qualifying leaseholders to participate, and the building must meet certain criteria set out in the Commonhold and Leasehold Reform Act 2002.
Once the RTM company is established, leaseholders can appoint a new managing agent or self-manage. We've seen this work brilliantly in buildings around /estate-agents/kensington, where engaged residents have cut service charges by 20-30% while improving standards. It does require commitment and organisation, but for many leaseholders it's worth the effort. The Leasehold Advisory Service (part of GOV.UK) offers free guidance on the RTM process.

Step 1 of 2What to Check Before You Buy
When viewing flats, always ask who the block management company is and research their reputation. Check online reviews, ask current residents about responsiveness, and request copies of recent service charge accounts and the building's reserve fund statement.
Look at the physical condition of communal areas during your viewing. Neglected hallways, broken lifts, or poorly maintained gardens often indicate poor block management. If you're looking at /property-to-rent/kensington or anywhere across London, these same checks apply to rental properties too. Your solicitor should also review the lease carefully during conveyancing, particularly clauses about service charges, major works provisions, and any restrictions that might affect your use of the property. A good /valuation will factor in management quality when assessing the property's worth.

Frequently asked
- Can I choose my own block management company?
- Individual leaseholders cannot unilaterally change the managing agent, as they're appointed by the freeholder. However, if at least half the qualifying leaseholders participate, you can exercise the Right to Manage and then appoint your preferred block management company.
- What's the difference between a freeholder and a block management company?
- The freeholder owns the building and the land it sits on. A block management company is the professional firm appointed by the freeholder (or Right to Manage company) to handle day-to-day administration, maintenance, and financial management of the building.
- Are block management fees the same as service charges?
- No. The block management company's fee is one component of your total service charge. Your service charge also covers insurance, repairs, maintenance, utilities for communal areas, staff costs, and contributions to the reserve fund.
- How much should I budget for service charges in London?
- According to HomeOwners Alliance, London leaseholders pay an average of £1,800 annually, but this varies enormously. Always review at least three years of accounts before buying, and budget for potential major works contributions on top of annual charges.
- What happens if my block management company goes bust?
- The freeholder or Right to Manage company must appoint a new managing agent. Your service charge funds should be held in a separate client account, protecting them if the management company fails. Check that your block management company is a member of ARMA or RICS for additional protection.
