Heat pump installers in Portsmouth: MCS-certified directory

How we rank installers

Installers shown above are filtered to those:

• Listed on the official MCS-certified directory (mcscertified.com).
• Approved to certify air-source heat pump installs (cap_air_source_heat_pump = true).
• BUS-registered — meaning they can apply the £7,500 Boiler Upgrade Scheme grant to your install.
• Within a sensible distance of the Portsmouth centroid. We widen the radius automatically if installer density is low in your area.

Ratings come from Google verified reviews, fetched via the official Google Places API with attribution. We show a rating only when it’s current (refreshed in the last 30 days). Installers without a Google Business listing don’t show a rating — we don’t fabricate stars.

What happens when I click “Request a quote”

We don’t hand over your phone number or email to the installer until you decide. The flow:

1. 5-minute property check. Enter your address; we pull your EPC, check Solar / heat-pump suitability based on roof + floor area + heating type.
2. Personalised report. We tell you whether your home is a good fit, indicate sizing + cost ranges, and flag any insulation prerequisites that need clearing for the BUS grant.
3. You decide.If the report says you’re a fit, you can book a meeting directly with the installer you chose. We share your details only then — never automatically.
