SEO for HVAC Engineers
Across London & the Home Counties
Rank for Boilers, Not Light Bulbs.
You're Worcester Bosch accredited, Vaillant trained and Mitsubishi approved, and Google still 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.
Why are London HVAC engineers losing heat pump enquiries to companies with less experience?
Search demand for heat pump installation in London has grown as the Boiler Upgrade Scheme has expanded, but most established Gas Safe engineers don't rank for those searches. They haven't built heat pump service pages, haven't published their MCS certification visibly, and aren't listed in manufacturer find-an-installer directories. The companies winning heat pump enquiries online often have less field experience. They just have the right pages. For an MCS-certified engineer who already does the work, that visibility gap is fixable. The same pattern applies to boiler servicing and AC installation. Each is a separate search category, and a single "services" page captures none of them.
Sound familiar?
Heard yourself say any of these?
"British Gas, EDF and Octopus 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 three or four businesses, and each one gets found differently
Boiler repair & replacement
Combi swaps. System upgrades. Breakdown callouts.
The map pack takes repair calls like 'boiler breakdown Hackney' and 'emergency heating engineer near me.' Manufacturer organic results and 'find an installer' locators take installation leads. British Gas and the energy companies hold the broad searches, but 'Worcester Bosch installer Islington' or 'boiler replacement Lewisham' are winnable. You need one page per service, per manufacturer accreditation and per core borough.
Air conditioning
Split systems. Multi-splits. Ducted. Commercial.
Highly seasonal. Volume spikes April to July, then 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. Separate split-system, multi-split and commercial AC pages, each ranking for its own search, let 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 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 moves the needle
Eight things that work for London heating and AC installers specifically.
HVAC SEO has a certification and manufacturer layer that most agencies don't understand and most installer sites ignore. These eight levers work with that layer.
01
Split service pages aggressively, because 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 and commercial ventilation are each 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 explained on the page instead of logos in the footer
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,' and 'do I need MCS for a heat pump grant'. All three are 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
Searches like 'Worcester Bosch installer Hackney,' 'Daikin air con installer London' and 'Mitsubishi Ecodan installer [borough]' have real 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: one of the biggest content gaps 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 captures the entire research-mode buyer before they've spoken to anyone. That means eligibility criteria, what MCS certification means for the grant, how the application works and what happens after install. Most heat pump pages have a one-line mention of the grant. The page that answers the question properly ranks and converts.
05
London property type content 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 can tell the difference. Write for the boroughs where you have actual job history.
06
Manufacturer locator listings, the lead source most agencies miss
Manufacturer locator pages like Worcester Bosch 'Find an Installer,' the Daikin Pro Partner locator, the Mitsubishi Approved Installer directory and Vaillant Advance Partner search 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, so the site works 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 that mention kit names and property types are the ones that 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' does far more than 'great service 5 stars' for GBP ranking and AI search. The product names, the property type and the borough feed search ranking signals, and they're the details AI tools look for 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, because 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. There, the site's only job is to survive a 90-second shortlist check. 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.

I start with our free SEO audit, the Visibility Snapshot. It covers four areas: your website, your Google Business Profile, where you rank today for your three main searches, and whether ChatGPT and Google AI Overviews mention you. Most HVAC firms split their work across boilers, AC and heat pumps, so I pick the three searches that matter most for the work you want more of. You get a written report by email within one working day.
For an HVAC firm, those might be "air conditioning installation Westminster", "heat pump installer Westminster" and "boiler service Westminster". I report Google and Maps positions separately, because you can rank well in one and be missing from the other. The Snapshot is about where you are today. Backlink audits, ranking history, competitor reports and reviews of another agency's work sit outside it, and I don't need logins for anything.

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 win 'new boiler London' and 'boiler installation London', which are broad, high-competition searches with enormous ad spend behind them. They don't win '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 needs its own page with real depth, and so does install versus repair versus service within each one.
Should my site explain the Boiler Upgrade Scheme in detail?
Yes, and almost no installer site does it properly. The BUS grant is one of the biggest content gaps in the heat pump trade. Buyers search 'BUS grant eligibility,' 'how does the Boiler Upgrade Scheme work' and '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.
How do manufacturer locator tools affect my SEO and should I be doing anything with them?
Manufacturer locator pages (Worcester Bosch 'Find an Installer,' the 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 such as M&E consultants, facilities managers and 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, with 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.'
How is this different from the last SEO agency I used?
I'm one person and I do the work myself. There's no account manager passing your brief to a writer who doesn't know what MCS means. Each month you get a plain written summary: which certification and service pages moved, what the manufacturer listings look like, where the seasonal coverage stands going into the next demand peak. You won't get ranking graphs. The measure is whether you got more jobs from it. The Snapshot is free. It shows where you rank today for your three main searches, whether that's boilers, heat pumps or AC, on Google and on Maps, and the one thing I'd fix first.
