What is an MCS-certified installer?

MCS (Microgeneration Certification Scheme) is the UK's quality assurance scheme for low-carbon heat and power technologies. An MCS-certified heat pump installer has met the scheme's competence requirements, follows MCS installation standards (MIS 3005 for ASHP), and registers each install on the MCS database. Crucially, MCS certification is required for any property to receive the £7,500 Boiler Upgrade Scheme grant — Ofgem only pays the grant if the installer holds active MCS status at the point of install.

How are installers ranked on Propertoasty?

We geo-filter by straight-line distance from your area's centroid (town centre, local authority centre, or postcode district centre depending on which page you're on), widening the radius automatically when installer density is low so the section doesn't render empty. We then rank by a Bayesian-smoothed Google review score — installers with very few reviews are damped toward the national average so a 5★/3 doesn't beat a 4.8★/200. Distance is the tie-break. Sponsored installers (clearly flagged with a 'Sponsored' badge) float to the top of the list; the same Bayesian ranking applies between them, and they pay double credits per accepted lead in exchange for the placement. We never fabricate ratings — Google verified reviews are shown when available, otherwise no stars row.

Why do you ask me to do a property check first?

Two reasons. (1) For the homeowner — heat pumps don't suit every property. The 5-minute check uses your EPC, Google's Solar API, and our floorplan analysis to give you a fit assessment BEFORE you spend an installer's time. About 15% of homes that start the check find out they need fabric work first — saving them and the installer a wasted site visit. (2) For the installer — they want qualified leads with property context, not blind enquiries. The check produces an installer-ready report that arrives with the booking, so the first conversation is about the install, not about discovery.

What happens to my contact details?

Nothing automatic. You enter your contact details during the property check; we use them to send your report to you. The installer you picked DOES see your details once you book a meeting with them — explicit opt-in. We never spam installers with your details, never auto-share, never sell your data. Full privacy policy at /privacy.

How do you make money if you're free for homeowners?

Installers pay a small per-lead fee when a homeowner books a meeting with them. Roughly £20-£50 per booked meeting depending on the technology. This is a fraction of what installers spend on traditional lead-gen channels (Google Ads, Checkatrade subscriptions, lead-broker fees), and they get fully-qualified leads with property data + photo, so the economics work for them. Free for homeowners; sustainable for the platform.

What if there's no installer covering my postcode?

For most UK postcodes there are 3-10 MCS-certified installers within a 25 km radius. Rural areas (mid-Wales, Lake District, parts of Scotland) sometimes have lower density — we widen the search radius automatically up to 200 km, so installers willing to cover that area still appear. If absolutely none are found, the page tells you and routes you to the property check, where we'll search live against the MCS directory for any installer covering your specific postcode.

About the directory

Propertoasty’s heat pump installer directory is built from the official MCS-certified register (mcscertified.com), updated monthly. We filter to installers approved for air-source heat pumps (the dominant residential technology) who are BUS-registered — meaning they can apply the £7,500 Boiler Upgrade Scheme grant directly to your install invoice.

Each installer card shows: MCS certificate number, BUS-registered status, years in business (where Companies House data is available), Google verified reviews (when a Google Business listing exists), and a Checkatrade verification link-out (when present). Sponsored installers are clearly flagged with a “Sponsored” badge. We don’t fabricate ratings — if Google has no data for an installer, we simply don’t show a stars row.

What makes a good heat pump installer

Beyond MCS certification, four signals are worth weighing when comparing installers:

BUS registration. Required for the £7,500 grant — non-negotiable. Every installer in this directory is BUS-registered.
Years in business. A 3+ year track record means the company has weathered at least one heating season and one BUS application cycle. Younger firms can be excellent but offer less historical data to assess.
Google review depth. A 4.5+ rating across 20+ reviews is a much stronger signal than 5.0 across 2 reviews. The number of reviews matters as much as the score.
Specialism match. An installer who fits only air-source heat pumps may be more focused than one who does ASHP + GSHP + solar PV + biomass + battery storage. Specialists often have shorter install timelines and more confident sizing decisions.

The customer journey explained

When you click “Request a quote” on any installer card:

We take you into a 5-minute property check (your address, a quick floorplan upload, a couple of questions about your existing heating).
We generate a free personalised report — suitability verdict, sizing range, EPC context, BUS grant eligibility.
If the report says you’re a fit, we offer to share your report + contact details with the installer you picked, and you book a meeting with them directly. We never share before that opt-in.
