How We Choose Heat Pump Installers in Bristol

Why we publish this

When you send an enquiry through this site, it goes to one installer from our network. That’s only worth doing if you can see how that installer was chosen. This page sets out the criteria, and every one of them can be checked against a public register, so you don’t have to take our word for it.

Two requirements

MCS certification

The Microgeneration Certification Scheme (MCS) assesses installers of renewable heating against standards for design, installation and commissioning. Since 28 April 2026, MCS certification has been a legal condition of the Boiler Upgrade Scheme, so without it there is no £7,500 grant. MCS installers must also belong to a consumer code (RECC or HIES), which sets rules on contracts, deposits and complaints.

Check it yourself: search the company name on the MCS website’s installer search.

Working in the Bristol area

A heat pump installation takes several days on site and needs aftercare. We look for installers who genuinely work across Bristol, South Gloucestershire and North Somerset — not a distant firm that lists Bristol on its website. Local experience matters here: stone and solid-brick period homes, steep gardens, a high share of conservation areas and hard water all affect the design.

Check it yourself: ask where their recent installations have been, and for a local customer you can speak to.

Three things in an installer’s favour

TrustMark registration

TrustMark is the government-endorsed quality scheme for work in and around the home. It isn’t required for a heat pump, but it adds another layer of standards and complaints handling.

Check it yourself: the TrustMark website has a search by business name.

Manufacturer approval

Major manufacturers such as Vaillant, Mitsubishi Electric, Daikin, Samsung and Grant run approved-installer programmes. Approval usually means brand-specific training and, often, access to longer warranties.

Check it yourself: most manufacturers have a find-an-installer page.

Heat pump design training

Heat pump design is a specialism. Independent training bodies such as Heat Geek recognise installers who have shown depth in low-temperature design, which is particularly useful in Bristol’s older, solid-walled homes.

Check it yourself: look for the installer on the training body’s directory.

What we don’t do

We don’t install, service or repair heat pumps.
We don’t publish reviews or star ratings we can’t verify.
We don’t send your enquiry to several companies at once.

If something goes wrong

If an installer we introduced you to doesn’t meet these standards, or their certification lapses, please tell us at privacy@bristol-heatpumps.co.uk. We’ll stop passing them enquiries while we look into it.
