The physical building work on a managed block is rarely where these projects go wrong. The mistakes that recur are almost always about how the process was run — consultation, access, specification and communication — and they surface as disputes rather than defects.
Recognising the common patterns early makes it much easier to run a smooth process, since the fixes are procedural rather than technical.
Rushing or compressing the consultation process
Attempting to shorten statutory consultation notice periods, or consulting on an incomplete specification with the intention of refining detail afterwards, both create legal and practical risk — leaseholders can challenge inadequately consulted charges, and refining detail post-consultation often means running the notice period again. The process has to be followed properly and with a genuinely finished specification from the start.
This mistake usually comes from an urgency to get works started, but the time lost re-running a flawed consultation is almost always greater than the time that would have been spent doing it properly first.
Assuming access without confirming it
Planning a works programme that assumes internal access to every unit will be available when needed, without confirming this with residents in advance, is one of the most common causes of on-site delay on block projects. A single uncooperative or absent resident can hold up a whole phase of works if access wasn't secured ahead of time.
Building a documented access plan, with named contact points and confirmed windows for each unit, before the programme is finalised removes this as a live risk once works are underway.
Pricing communal works without a proper survey
Commissioning a fixed price for roofing, cladding or communal refurbishment based on a visual assessment alone, rather than a proper condition survey, often leads to variations once scaffolding goes up and the real condition of the structure is revealed. These variations then have to be justified to leaseholders, sometimes requiring a further round of consultation.
A thorough survey before pricing, even where it adds a small cost and a few days to the front of the project, generally produces a more accurate quote and far fewer disputed variations later.
Inconsistent specification without a documented reason
Allowing unit-by-unit variation in specification — one leaseholder gets a different window or door standard from their neighbour, without a clear and recorded reason — is a common and entirely avoidable source of dispute. Even where variation is genuinely justified by different unit conditions, if it isn't documented at the time, it looks arbitrary later.
Agreeing and recording the baseline specification and the conditions for any variation before works start on any individual unit avoids this becoming a retrospective argument.
Under-communicating during the works themselves
Leaseholders who only hear from the managing agent when there's a problem or a bill tend to assume the worst about ongoing works, even when the project is running to plan. A lack of regular, plain-language updates during the works is one of the most common complaints on block projects, independent of how well the actual building work is going.
Scheduled, brief progress updates — even simple ones — generally do more to prevent disputes than any amount of technical reporting produced only at the end.
Common questions
What happens if consultation is found to be inadequate?+
Leaseholders can challenge the recoverable service charge, potentially limiting what can be charged back, which is why the process needs following properly and with a finished specification from the outset.
How can access be confirmed before a programme is finalised?+
Through direct written contact with each resident or leaseholder, agreeing specific windows and a named point of contact, built into the programme as a documented plan rather than an assumption.
Is a full condition survey always worth the extra time before pricing?+
In most cases yes — the cost and time of a proper survey is generally small compared with the disruption and dispute risk caused by significant variations discovered once scaffolding is up.
