What is a Lead Aggregator

Full definition

A lead aggregator is a technology platform that acts as an intermediary between homeowners seeking trade services and the businesses that provide them. The platform invests in consumer-facing marketing — paid search, comparison listings, price-guide content, and SEO — to attract homeowners at the point of project intent. When a homeowner submits an enquiry specifying trade type, job description, location, and timeline, the platform routes that contact information to one or more matching tradespeople as a paid lead.

In the UK home improvement and construction sector, aggregators operate across every trade category: roofing, plumbing, electrical work, extensions, kitchen fitting, boiler installation, damp proofing, and dozens of others. Platforms range from generalist directories such as Checkatrade, MyBuilder, and Rated People to specialist marketplaces focused on a single trade category.

The two dominant commercial models are pay-per-lead — the tradesperson pays a fixed fee per enquiry received — and monthly subscription — a flat fee covers a defined allocation of leads in a given postcode area and trade type.

Why it matters for trades / trust signal

For a tradesperson without an established referral network or a high-ranking website, a lead aggregator provides immediate access to a pipeline of project enquiries without requiring upfront investment in SEO, Google Ads, or brand building. This makes aggregators the primary customer-acquisition channel for many sole traders and small contracting firms in competitive urban markets.

However, aggregators represent a rented audience rather than an owned one: a change in the platform's pricing, algorithm, or terms of service can eliminate a significant portion of a contractor's lead volume overnight. Trades that rely entirely on aggregator leads therefore carry platform dependency risk that those with strong organic search presence, accreditation-driven inbound, or direct referral networks do not.

The quality signal aggregators provide to homeowners is also distinct from accreditation bodies: most platforms rely on consumer reviews rather than independent inspection, meaning a contractor with no complaints is listed alongside one vetted to TrustMark or FMB standards.

How to get listed / registered

Each aggregator has its own onboarding process, but common steps across UK platforms include:

1. Create a business profile: Trade category, service area (postcode radius), business name, and description.
2. Submit verification documents: Public liability insurance certificate and proof of relevant trade qualifications or registrations (Gas Safe, NICEIC, etc.) where applicable.
3. Set lead preferences: Trade types, job sizes, and geographic radius.
4. Choose a pricing plan: Pay-per-lead or subscription, depending on the platform's available models.
5. Build a review profile: Most platforms weight lead distribution in favour of businesses with higher review scores, making early review collection operationally important.
