Worcester Bosch accredited. Vaillant trained.
Mitsubishi approved. And Google thinks you change light bulbs.
Your certifications are the thing that separates you from the uncertified operators undercutting on heat pump installs and the chains buying every AC search. The problem is Google can't find them. Your site doesn't explain what they mean, and you don't have the pages that rank for the searches your actual buyers do.
"British Gas, EDF, Octopus — they own the boiler search results. Customer Googles 'new boiler London' and I'm on page 4 behind three energy companies and a comparison site."
"Heat pump grants brought every electrician and plumber into the game. Half of them aren't MCS certified and they're quoting £4k under me for installs that'll fail the BUS grant audit."
"Air con was my summer earner. Now everyone's installing it. The chains buy the search results and I'm scrapping over the leftovers."
"Worcester Bosch accredited, Vaillant trained, Mitsubishi air con approved. None of it shows up on Google. I look like the same Gas Safe bloke as everyone else."
"Commercial AC and ventilation work is where the money is. But it comes through M&E consultants and FM companies, and my website doesn't look like a business they'd put in front of a client."
The reality
HVAC is really three or four businesses — and each one gets found differently
Boilers — repair & replacement
Combi swaps. System upgrades. Breakdown callouts.
The map pack takes repair calls — 'boiler breakdown Hackney,' 'emergency heating engineer near me.' Manufacturer organic results and 'find an installer' locators take installation leads. British Gas and the energy companies dominate the broad searches, but 'Worcester Bosch installer Islington' or 'boiler replacement Lewisham' are winnable. One page per service, one page per manufacturer accreditation, one page per core borough.
Air conditioning
Split systems. Multi-splits. Ducted. Commercial.
Highly seasonal — volume spikes April to July and drops sharply. F-Gas certification is the trust signal buyers check, and manufacturer approval (Daikin, Mitsubishi, Panasonic) is what converts the serious buyer. Most installer sites bury AC under a 'services' tab. A dedicated split-system page, a multi-split page, a commercial AC page — each ranking for its own search — is how you win the category without competing on Google Ads with Aircon Direct.
Heat pumps & ventilation
ASHP. GSHP. MVHR. BUS grant installs.
Grant-driven and research-heavy. The buyer reads for weeks before calling anyone. MCS certification is non-negotiable for the BUS grant — and it's a signal that filters out the uncertified operators who flooded the market. A site that explains the grant clearly, states MCS registration plainly, and shows real case studies from London property types converts this buyer. Most heat pump pages have a grant mention and nothing else.
What actually moves the needle
Eight things that work for heating and AC installers in London specifically.
HVAC SEO has a certification and manufacturer layer that most agencies don't understand and most installer sites completely ignore. These eight levers work with that layer.
01
Split service pages aggressively — boilers, AC, and heat pumps are separate businesses
A boiler installer's site that lumps 'air conditioning' into one paragraph never ranks for AC searches. Full boiler replacement, boiler repair, boiler service, split-system AC, multi-split AC, ducted AC, air source heat pump, ground source heat pump, MVHR, commercial ventilation — each is a different buyer at a different price point with a different search intent. Then within each service: install, repair, service, design. Most competitor HVAC sites do all of this on two or three pages. That's why they rank for nothing specific.
02
Certifications as page content — not footer logos
Gas Safe registration number visible, F-Gas company certificate referenced, MCS registration number if you're doing heat pumps, manufacturer accreditations explained in one sentence each. Customers Google 'what is Gas Safe,' 'what is F-Gas certification,' 'do I need MCS for a heat pump grant' — all real searches with real volume. The site that answers those questions ranks for them and is already the credible expert when the buyer is ready to call. Most competitor sites dump the logos and never explain what any of them mean.
03
Manufacturer partnership pages — a ranking opportunity almost nobody builds
'Worcester Bosch installer Hackney,' 'Daikin air con installer London,' 'Mitsubishi Ecodan installer [borough]' — these are real searches with buying intent and most installer sites have no dedicated pages for them. Build one page per manufacturer you're approved for. Explain what the approval means, what the manufacturer warranty covers, and what jobs you've completed with that equipment. Each page links to the manufacturer's 'find an installer' directory, which builds authority in both directions. It's the kind of thing that's obvious once you see it and almost no one does it.
04
BUS grant content — the biggest content gap in the heat pump trade
The Boiler Upgrade Scheme offers £7,500 toward air source heat pumps in England. Buyers Google 'BUS grant eligibility,' 'ASHP grant London,' 'is my house suitable for a heat pump,' 'how does the Boiler Upgrade Scheme work.' The installer site that explains this properly — eligibility criteria, what MCS certification means for the grant, how the application works, what happens after install — captures the entire research-mode buyer before they've spoken to anyone. Most heat pump pages have a one-line mention of the grant. The page that answers the question properly ranks and converts. [Verify current grant amount and scheme status before publishing.]
05
London property type content — this is where generic HVAC advice fails
An air source heat pump in a Camden conservation area needs planning consideration that a Bromley semi doesn't. A Victorian conversion flat in Stoke Newington has different boiler replacement constraints than a 1980s ex-LA flat in Lewisham. A period terrace in Islington needs different ventilation thinking when windows get replaced. Real local property knowledge on the page — the specific housing stock, the planning sensitivities, the typical complications by borough — outperforms find-and-replace borough templates and Google filters the difference. Write for the boroughs where you have actual job history.
06
Manufacturer locator listings — the lead source most agencies miss
Worcester Bosch 'Find an Installer,' Daikin Pro Partner locator, Mitsubishi Approved Installer directory, Vaillant Advance Partner search — these manufacturer locator pages rank on their own and refer buyers directly to listed installers. Being listed, keeping your profile complete, and having your manufacturer pages on your own site link back to the locator creates a two-direction authority signal. Most installers are listed but have never optimised their profile or built the reciprocal content. That's the gap.
07
Seasonal content — the site should work differently in May than in November
Boiler content ranks year-round but peaks September to December. Air con content peaks April to July. Heat pump content runs steady year-round with grant-cycle spikes when policy changes. The GBP posts, the homepage hero messaging, and any paid campaigns need to rotate with demand. Most installer sites have the same homepage in January as they do in July. That's leaving seasonal search volume on the table. It's also a simple thing to fix.
08
Reviews with kit names and property types — the signals that actually move rankings
'Installed our Mitsubishi Ecodan air source heat pump in a 1930s semi in Sutton, sorted the grant paperwork, system's been faultless through winter' outperforms 'great service 5 stars' for GBP ranking and AI search citations by a significant margin. The product names, the property type, the borough — these feed both search ranking signals and the AI citation logic that recommends specific installers when someone asks ChatGPT 'best heat pump installer for a Victorian terrace in South London.'
The numbers
Three boiler replacements a month covers SEO. One heat pump job covers most of the year.
The pitch here isn't lead volume — HVAC doesn't need dozens of leads a month. It needs the right ones. The buyer who finds you through a well-built manufacturer partnership page or a proper BUS grant explainer is already qualified. They know what they want, they've seen your certifications, and they're not phoning six other installers to compare on price.
On the commercial side, the economics shift completely. One commercial AC contract with a hotel group, a restaurant chain, or an FM company is worth more than thirty domestic boiler jobs. The site's job there isn't to generate volume — it's to not lose the shortlist in 90 seconds. Most HVAC sites fail that test because they look domestic when the M&E consultant opens them.
Air source heat pump (after BUS grant)£3,000–£8,000
Air source heat pump (gross, pre-grant)£10,500–£15,500
MVHR system (whole home)£3,500–£8,000
Commercial AC (per zone)£2,000–£5,000
One air source heat pump installation at gross value covers most of a year's SEO. Three boiler replacements a month covers it comfortably.

Common questions
Questions heating and AC installers ask before getting in touch
Can a heating engineer or HVAC installer realistically compete against British Gas and the energy companies on Google?
Yes, at the borough and service level. British Gas and Octopus dominate 'new boiler London' and 'boiler installation London' — broad, high-competition searches with enormous ad spend behind them. They don't dominate 'Worcester Bosch installer Lewisham' or 'boiler replacement Hackney' or 'Daikin air con installer North London.' Specific service and location combinations have real buyer intent and much weaker competition. A sole trader with the right manufacturer partnership pages and borough content can rank above the national brands on those searches.
Do I need completely separate pages for boilers, air conditioning, and heat pumps?
Yes. They are different buyers, different search terms, different certifications, and different decision timelines. The homeowner replacing a boiler is not the same person as the one researching a heat pump grant, and neither is the business owner pricing a commercial AC system. One 'heating and cooling services' page competes for none of those searches properly. Each service — and within each service, install versus repair versus service — needs its own page with real depth.
Should my site explain the Boiler Upgrade Scheme in detail?
Yes, and almost no installer site does it properly. The BUS grant is the single biggest content gap in the heat pump trade. Buyers search 'BUS grant eligibility,' 'how does the Boiler Upgrade Scheme work,' 'is my house suitable for a heat pump' — these are high-intent research queries with weak competing pages. A clear, accurate explainer covering eligibility, what MCS certification means for the application, the install process, and what happens after the grant is processed will rank quickly and capture buyers at the earliest research stage. Verify the current grant amount and scheme status before publishing.
How do manufacturer locator tools affect my SEO and should I be doing anything with them?
Manufacturer locator pages — Worcester Bosch 'Find an Installer,' Daikin Pro Partner directory, Mitsubishi Approved Installer search — rank on their own and refer buyers directly to listed installers. Keeping your manufacturer profile complete and building dedicated manufacturer pages on your own site that link back to the locator creates a two-direction authority signal. Most installers are listed but have never optimised their profile or built the reciprocal site content. It's a low-competition, high-intent ranking opportunity.
How long before SEO starts generating heating and AC leads?
For Google Business Profile work — photos, review strategy, GBP posts aligned to the season — map pack movement for borough-level boiler and AC searches typically takes 4–8 weeks. For organic service and manufacturer partner page rankings, 3–5 months is realistic. Heat pump and BUS grant content often ranks faster because competition on those specific searches is weaker — most installers aren't writing the informational content buyers are searching for.
My business does both domestic and commercial HVAC. Do I need a separate commercial section?
Yes, if commercial work is a real part of your revenue. Commercial buyers — M&E consultants, facilities managers, hotel operations teams — shortlist in 90 seconds based on whether the site looks capable of handling their job. A domestic boiler photo on the homepage kills commercial credibility. The commercial section needs case studies, industry sector experience, the types of systems you specify and install, and any named client work you can reference. It doesn't need to be large. It needs to look like the business you actually are.
What does AI search visibility mean for a heating engineer or AC installer?
It means appearing when someone uses ChatGPT, Perplexity, or Google AI Overviews to research HVAC work — questions like 'best heat pump installer for a Victorian terrace in South London' or 'MCS certified ASHP installer Hackney' or 'who installs Mitsubishi air con in North London.' These tools cite websites that directly answer those questions with named certifications, specific equipment, real property experience, and stated service areas. An HVAC site with manufacturer partnership pages, grant explainer content, and certification-specific service pages is far more likely to be cited than one with generic copy about 'heating and cooling solutions.'
