How We Tripled Profitability for the UK's Leading Hot Tub Brand

Lay-Z-Spa were spending at serious scale on Google Ads, but growth was starting to cost them margin, not build it.

The brief

Lay-Z-Spa is the UK's most renowned, most energy-efficient, and most 5-star reviewed inflatable hot tub brand. They brought us onto their PPC account to improve Google Ads performance, lift return on ad spend, and build a long-term strategy fit for their year-on-year growth targets.

The challenge

The account was already advertising at scale, but scale was working against them. Beyond a certain spend level, returns diminished and ROAS became inconsistent, exactly when their margins needed it to hold steady. A highly seasonal product added another layer of difficulty: the strategy needed to capitalise fully on summer demand while still investing in brand building and data nurture through the off-season, the groundwork that makes the next peak season bigger than the last.

What we did

We started with an in-depth audit of the existing account, which surfaced multiple areas of suboptimal spend and structural wastage. Over three months we ran a full 20-point PPC audit alongside a complete copy and asset review, rebuilding bidding structures, improving ad rank, and optimising the Google Merchant Centre product feed. Every part of the account was rebuilt to channel budget toward what actually drove profit, not just volume.
