Loft Conversions, Extensions and Bathroom Renovations: Which Trade Gets the Most Leads from Google in South London?

One of the most common questions we get from South London trades businesses is some version of: 'Is it even worth doing SEO for my trade?' The answer is almost always yes — but the opportunity varies significantly depending on what you do.

Here's what the search data actually shows for South London — and what it means for where you should be investing your marketing budget.

The search volume breakdown by trade

Based on keyword research across South London postcodes, here's how monthly Google search volumes compare across the most common home improvement trades:

• Kitchen fitting — 1,200–2,400 searches/month across South London. High intent, high average job value (£10k–£40k). Very competitive but extremely rewarding to rank for
• Bathroom renovation — 800–1,600 searches/month. Similar profile to kitchens — high value, high competition, strong ROI on SEO investment
• Loft conversions — 600–1,200 searches/month. Fewer searches but average job values of £30k–£80k make each lead extremely valuable
• Extensions — 500–1,000 searches/month. Similar to loft conversions — lower volume, very high value per job
• General builder — 1,500–3,000 searches/month. Highest volume but most competitive and broadest intent — harder to convert than specific trade searches
• Electrician — 900–1,800 searches/month. Split between residential and commercial. Strong local intent
• Plumber — 1,200–2,400 searches/month. High volume, often emergency intent — good for Google Ads, strong for local SEO
• Painter and decorator — 400–800 searches/month. Lower volume but lower competition — easier to rank, lower average job value

What this means in practice

If you're a kitchen fitter or bathroom renovator in South London, the search volume justifies significant SEO investment — the combination of volume, intent and job value means even ranking for a handful of local searches delivers strong ROI.

If you're a loft conversion or extension specialist, the volume is lower but each lead is worth more. A single job won from Google could be worth £50k+. Even 5–10 organic enquiries a month from a well-executed SEO strategy represents a transformative return.

If you're a general builder, the opportunity is real but the strategy needs to be specific. 'Builder South London' is competitive. 'Builder Clapham' or 'builder Dulwich' are significantly more achievable — and the homeowners searching those terms are closer to hiring.

The competition picture

Search volume only tells half the story. The other half is how many other businesses are competing for those searches. In South London, the trades with the highest search volume — kitchen fitting, bathroom renovation, general building — also have the most competition.

This doesn't make them impossible to rank for. It means the businesses that invest properly in SEO — complete Google Business Profile, strong reviews, well-optimised website, consistent content — will consistently outperform the majority who don't.

In our experience across South London, most trades businesses in any given area have done very little SEO. The bar to outrank them is lower than most people assume.

The geographic factor

Search volume also varies significantly by South London borough. Clapham, Dulwich, Wandsworth and Battersea generate more home improvement searches than areas further out — partly because of higher property values and homeowner demographics, and partly because there are simply more searches happening in denser areas.

If you're targeting multiple South London boroughs, it's worth knowing which ones generate the most searches for your specific trade — and prioritising your local SEO and Google Ads targeting accordingly.
