Preparing for the autumn surge: how top-performing branches protect completion rates when volume spikes

By Michael Grimsley, National Account Manager, at Nova Conveyancing

Every autumn, the same pattern plays out. A slower summer gives way to a rush of listings and offers, and branch teams that were coasting in August are suddenly managing double the caseload with the same headcount. This year the pattern is sharper than usual. Zoopla’s own data showed agreed sales running around 9% behind last year through the summer lull, and the portal is now forecasting a busier-than-usual return of buyers as September wears on. Layer on a Budget on 28 October that’s already put buyers and sellers into a pricing stand-off, according to estate agent Jeremy Leaf, and what typically arrives as a steady fourth-quarter uplift risks landing instead as a compressed sprint: fewer working weeks, more live files, and a harder push to exchange and complete before Christmas.

Branch leaders know what happens next if nothing changes. Caseloads climb faster than capacity, and completion rates come under pressure not because anyone is doing a worse job, but because the systems that hold a transaction together were built for a calmer pace.

It’s worth being precise about where that pressure actually lands. Fall-throughs are rarely caused by volume on their own. GOTO Group’s 2024 analysis put the UK’s fall-through rate at 29.8%, almost double the 16% recorded in 2022, with survey issues and mortgage difficulties accounting for the largest share of failures, and conveyancing bottlenecks compounding both. What volume spikes do is remove the slack that normally absorbs those existing risks. A case that would have had a named contact chasing a lender for an update now sits in a queue. A chain that would have had proactive visibility at each link goes quiet for a week, and silence at exactly the moment stress is highest is what pushes a wavering buyer or seller to walk.

That’s the real difference between branches that hold their completion rate through a volume spike and those that see it slip. It isn’t speed. Working faster with the same structure just moves the same risks through the pipeline more quickly. What protects completion rates is whether ownership and visibility survive the pressure intact.

In practice, that looks like a handful of disciplines. Every file keeps a named point of contact from instruction through to completion, so nobody is starting cold when a case escalates. Updates go out on a set rhythm agreed with the client and the referring agent in advance, because silence reads as risk whether or not anything has actually gone wrong. Chain visibility gets checked proactively, so a delay two links away is known before it becomes a surprise on completion day. And cases are triaged by genuine risk rather than simply by how long they’ve been open, so a mortgage offer nearing expiry gets attention before a straightforward cash purchase that can wait a few more days.

None of this depends on hiring ahead of the curve or promising clients a faster move than the market can deliver. It depends on whether the operational structure underneath the branch can flex without losing track of any individual case, which is a different problem to solve than simply working harder through October and November. Branches that get this right tend to have agreed it in advance, before the volume arrives, rather than trying to build the discipline into a process that’s already under strain.

For agency leadership weighing up conveyancing partnerships ahead of Q4, that structural question is worth asking directly: what happens to visibility and communication on your branches’ files when volume doubles overnight? A partner’s average turnaround time on a good week says very little about that. It’s also worth asking how consistently that answer holds across every branch, not just the flagship ones, since a partnership that performs well in one office and unevenly in another creates exactly the kind of inconsistent experience that erodes trust with agents and clients alike. The answer tends to separate partners who scale well from those who only perform well when things are quiet, and it’s a much better predictor of what your completion rate will actually look like in December than any headline turnaround time.

The branches that come through the autumn surge with their completion rates intact aren’t the ones that moved fastest. They’re the ones whose process didn’t need to change shape under pressure, because it was built to hold at volume in the first place.
