Lomax & Wood is a specialist in premium timber windows and doors with over 30 years of craftsmanship. The company provides bespoke, sustainably made windows, doors, and orangeries for projects across the UK. In 2025, Lomax & Wood became a UK Employee Owned Trust, securing long-term continuity while keeping founders Chris Wood, Yvonne Wood, and Andrew Goding active in the business.
The previous PPC agency delivered inflated headline metrics that didn’t translate into real enquiries. Campaigns were dominated by irrelevant targeting and unmonitored Performance Max activity, which drove impressions and clicks but did little to capture people who were ready to buy. The account lacked structure, intent alignment, and ongoing optimisation. As a result, the cost per acquisition was high at £269.29, and the conversion rate was stuck at 0.13%.
We rebuilt every campaign around clear search intent. This meant restructuring the account, removing irrelevant targeting, pausing unfocused PMax activity, and tightening keyword groups. We introduced negative lists, improved match types, and kept refining this throughout the year. The results show the difference a structured, data-led setup can make: a 75% fall in CPA, more than triple the number of conversions, and a jump in conversion rate from 0.13% to 5.35%.
“They’re just a really nice team to work with – it’s like an extension of our own team. Or even, more so – it’s LIKE they’re our own team.”
“Everyone that I’ve spoken to within Purplex has been really friendly, very helpful and they all have a great all-round knowledge of the industry – you’re not spending loads of time and effort having to train people.”
“Purplex in my experience have done really good work in SEO, the increase in website visits, click throughs and eventual orders is up is about 50% up on last year, so the website is really, really working.”
“It’s been an amazing transformation in terms of not only the growth of the business in terms of orders-in, but profitability as well.”
“Dekko has grown from £6m to £25m over the last 12 years and we simply couldn’t have achieved it without Purplex. Our brand is well recognised and the exposure we get through the press, social media and online consistently puts us in front of good quality prospects.”
