Commissioning roofing, cladding, guttering or communal refurbishment across a managed block involves the same trades as a single house, but multiplied across several units, several leaseholders, and a consultation process that a single-owner project doesn't have.
Understanding what that process actually involves in practice, rather than treating it as paperwork to get through quickly, is what keeps a block project on schedule.
Section 20 style consultation shapes the timeline
Where works are being charged back to leaseholders above certain cost thresholds, a formal consultation process is usually required before a contractor can be instructed, involving notice periods and an opportunity for leaseholders to comment or nominate alternative contractors. This process has statutory minimum timeframes that cannot be compressed, and should be factored into the project timeline from the very start rather than treated as a formality to rush through.
Getting the specification and quotation genuinely ready before the consultation starts — rather than consulting on an outline and refining detail afterwards — avoids extending the process with a second round of notices.
Access coordination across multiple occupied units
Roofing, guttering and cladding works often need internal access to individual units — for scaffolding tie-ins, internal inspection, or snagging — and coordinating that access across tenants and owner-occupiers with different schedules and availability is a genuine logistics task in its own right. Building a realistic access plan before works start, rather than assuming access as and when needed, avoids delays chasing down individual residents mid-project.
Clear, early communication to residents about what access is needed, when, and for how long generally produces far better cooperation than a short-notice request once the scaffolding is already up.
Consistent specification across units, not per-unit variation
Where multiple units on a block need similar works — kitchen or bathroom refurbishments in social housing blocks, for example, or window replacement across a terrace — applying a genuinely consistent specification avoids disputes between leaseholders about why one unit received a different standard from another. This doesn't mean every unit needs identical finishes regardless of condition, but the baseline standard and the reasoning for any variation should be documented and defensible.
A written specification agreed before works start, rather than decisions made unit by unit on site, is what makes this consistency achievable in practice.
Reporting that leaseholders can actually follow
Leaseholders paying into a service charge for major works expect clear reporting on progress, cost and any variations, and a lack of clear communication is one of the most common sources of dispute on block projects even where the physical work itself is done well. Regular, plain-language progress updates, rather than technical reports only understood by the managing agent, reduce queries and complaints during the works.
Where variations to the original scope arise — a common occurrence once scaffolding reveals the true condition of a roof, for example — these should be communicated and, where the consultation process requires it, notified formally before proceeding.
Programme certainty across a whole site
A block project typically runs to a longer, more structured programme than a single-house job, because scaffolding, access and consultation timelines all interact, and slippage in one area tends to cascade into the others. Building realistic float into the programme for consultation, access coordination and weather-dependent external works avoids the whole project sliding when one element runs late.
Communicating programme changes promptly to the managing agent and leaseholders, rather than only updating at scheduled milestones, keeps confidence in the project even when a delay does occur.
Common questions
Can Section 20 style consultation be skipped for urgent works?+
There are provisions for genuinely urgent works, but these have their own conditions and shouldn't be assumed to apply without checking — most works still need the standard process followed.
How is access to individual units usually arranged?+
Through advance written notice to residents specifying what access is needed and when, ideally coordinated well before scaffolding or works reach that part of the building rather than requested at short notice.
Should every unit on a block receive identical specification?+
Not necessarily, but the baseline standard should be consistent and any variation should be documented and justified, since undocumented inconsistency between units is a common source of leaseholder dispute.
