By Jake Perry, Founder, DigiSurf Agency.

We've audited hundreds of UK hvac & heat pump installers websites. The same seven mistakes show up every time. Fixing them is the difference between a site that sits idle and one that puts booked work on your calendar.

Mistake #1: Generic 'HVAC services' page

Air-source heat pumps, ground-source heat pumps, ducted air conditioning, MVHR, F-Gas servicing — five different markets with five different customers. A single 'HVAC' page wins nothing.

The fix: Build a dedicated landing page per system per city. ASHP installer {city}, GSHP {city}, air con installer {city}, MVHR specialist {city}. See HVAC London.

Mistake #2: Missing MCS certification

MCS-certified installers are the only ones who can register systems for the Boiler Upgrade Scheme £7,500 grant. Customers Google specifically for it. Hide MCS and you lose every grant-aware lead.

The fix: Lead with MCS certification + your MCS number. List in the hero. Link to your public MCS profile. The single biggest trust signal in UK heating right now.

Mistake #3: No Boiler Upgrade Scheme page

The £7,500 BUS grant is the #1 buying motivation for UK heat-pump customers in 2025-26. Most installers have nothing about it on the site.

The fix: Build a dedicated BUS page per city. Cover eligibility, application process, who qualifies, typical timeline. High-intent traffic, easy ranking.

Mistake #4: No heat-loss or ROI calculator

Customers want to know if their house will work with a heat pump and what the savings are. 'Call us for an assessment' converts under 2%; an interactive calculator converts 8-15%.

The fix: Build a simple postcode + property-type calculator. Output an annual savings estimate. Highest-converting tool on a heat-pump site.

Mistake #5: Stock photos with no installed-system context

Mitsubishi Ecodan, Daikin Altherma, Samsung EHS, Vaillant aroTHERM — customers research brands. Stock 'heat pump unit' photos do nothing.

The fix: Show real installs with the brand, the property type, the heat-loss calc result. Adds technical credibility.

Mistake #6: F-Gas registration hidden

F-Gas certified engineers are legally required for refrigerant work. Customers don't know the rule but Google does. Hide F-Gas and you miss commercial air-con tenders.

The fix: Display F-Gas registration + Refcom membership on every air-con page. Schema-tag it. Commercial customers verify before procurement.

Mistake #7: Missing HVACBusiness + GovernmentService schema

Schema.org's Service + GovernmentService (for BUS grant pages) + MedicalProcedure-style structured data triggers grant-aware rich results.

The fix: Add Service, Offer (with BUS pricing context), FAQPage schema. We build it in by default — see industries/hvac.
