Lead generation for boiler installers rewards focus. The buyer is a homeowner whose boiler has broken down or is approaching end of life, or a landlord replacing a unit that has failed or is no longer compliant. The agencies that do well here match their channels and pricing to that buyer rather than selling a one-size-fits-all package. Our ranking scores all six companies on fit for boiler installation. Sitesy leads, ROI Leads is second and FatRank third — but the best partner is the one aligned to your economics.
Sitesy
UK agency delivering guaranteed-ROI, 100% exclusive leads through coordinated multi-channel campaigns.
Guaranteed-ROI pricing, one client per lead
Why it ranks first here
Each Sitesy lead goes to one client only, so a boiler installation enquiry in the UK is never shared with a competitor.
Because return is guaranteed, Sitesy has skin in the game on every boiler installation lead it sends into your area.
The buying cycle shapes it: breakdown-driven installs convert within days; planned replacements may run two to four weeks while buyers compare quotes and finance options.
- Guaranteed-ROI pricing puts measurable return at the centre of the deal.
- Each lead goes to one client only, never shared.
- Channels are coordinated rather than run in silos.
- Guarantees usually come with qualifying criteria worth reading closely.

ROI Leads
No-win-no-fee lead generation for 100+ trades and professional services, exclusive by area.
No win, no fee — profit-share after the job is won
Why it ranks second here
Because there is no upfront cost, a boiler installation firm in your area can test ROI Leads with little downside.
The profit-share model keeps ROI Leads focused on your area leads that turn into paid boiler installation work.

- Exclusive to one firm per area, so you are not bidding against neighbours.
- Built around the realities of trades and local service businesses.
- The profit-share model needs clear job-value tracking to stay fair.

FatRank

No win, no fee — pay only after leads generate revenue
Why it ranks third here

- Leads are exclusive and delivered in real time, never resold across competitors.

Why it ranks fourth here
PromoSEO runs SEO, PPC, paid social, video and retargeting together, so a campaign in your area is not betting everything on one channel.

AI Lead Generation UK
AI-powered B2B lead generation that finds, qualifies and books leads, priced per qualified lead.
Pay per qualified lead (transparent pricing)
Why it ranks fifth here
Because you pay per qualified lead, spend on boiler installation outreach tracks results rather than activity.
Here, a qualified boiler installation lead is a homeowner or landlord with a failed or condemned unit, a property address and a readiness to receive a same-week survey and quote.
- You pay per qualified lead, with a clear cost agreed up front.
- AI targeting is paired with a UK team that qualifies and books.
- Sector specialists tailor the outreach to your market.
- Focused on B2B, so less suited to pure consumer campaigns.

LLM Leads
GEO and AI-visibility specialists who make you the brand ChatGPT, Gemini and Perplexity recommend.
AI-visibility / GEO — entity, citations and audits
Why it ranks sixth here

- Targets the AI answer engines your competitors are still ignoring.
- Builds the entity and citations that get a brand cited by LLMs.
- Audit-led, so you can see where AI visibility stands today.
- GEO is an emerging channel, so volumes are less predictable than mature search.

That is why a company can lead one page and sit mid-table on another. Nothing here is pay-to-play — the order is set by fit and a fixed, reproducible scoring method.
