How to judge a heat pump installer
Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each trader’s public evidence above.
Verify before you hire
- Check the installer holds an active MCS certification: only MCS-certified installers can access the £7,500 Boiler Upgrade Scheme grant and issue a valid warranty certificate.
- Confirm they are a RECC or HIES member, which gives you deposit protection and a free dispute resolution service if something goes wrong.
- Ask to see the heat loss calculation (BS EN 12831-1) for your home: no proper calculation means the system may be sized wrong and struggle in cold weather.
- Check their Companies House registration to confirm they are a real, trading company: heat pump firms can be very young, so trading history matters.
Warning signs of a cowboy
- An upfront deposit of more than 50% before work starts is a known fraud pattern in the heat pump sector: walk away.
- Any installer who says you can get the BUS grant without MCS certification is either mistaken or misleading you: MCS is mandatory.
- A quote that names a specific brand (e.g. Mitsubishi, Vaillant) but won't confirm the exact model in writing risks a cheaper substitution on installation day.
- No mention of a heat loss survey before quoting: an installer sizing a heat pump by guesswork is a serious red flag.
Questions to ask before you hire
- Are you currently MCS-certified for air source or ground source heat pumps, and can I verify this on the MCS register before signing anything?
- Will you carry out a full room-by-room heat loss calculation (BS EN 12831-1) before specifying the system size?
- Are you registered with RECC or HIES, and what deposit protection will I have?
- How many heat pump installations have you completed, and can you provide references from jobs similar to my property?
Frequently asked questions
- How do I choose a trustworthy heat pump installer?
- Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. A heat pump installer backed by several named sources is harder to fake than one found in only one place.
- Does MyTrustedTraders rank or recommend heat pump installers for payment?
- No. There are no ads and no paid placement. Heat pump installers are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
- Where do the reviews come from?
- They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
- What should I check before hiring a heat pump installer?
- Confirm credentials and insurance directly with the heat pump installer, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
