Who is the best heat pump installer in the UK?

It depends on your home. Prioritise MCS certification, a proper design survey and good reviews over brand name or price alone.

Are national or local installers better?

Both can be excellent. Local firms may cost less and know regional housing; nationals often offer broader guarantees. Compare on process and references.

How many heat pump quotes should I get?

At least three written quotes, each following a proper heat-loss survey, so you can compare design quality and price fairly.

Best Heat Pump Installers in the UK

There is no single 'best' heat pump installer for everyone — the right one depends on your home, location and expectations. Rather than a paid league table, this guide explains what actually separates a good heat pump install from a bad one, the certification that proves competence, and how to compare quotes with confidence.

What 'best' really means

A great install starts with a proper heat-loss survey and low-temperature design, not a like-for-like boiler swap. Look for strong aftercare, transparent warranties, and verifiable customer reviews. National and local firms can both be excellent — judge on process, not size.

Certification to check

For a grant-funded install, the installer must be MCS-certified — that's required to claim the £7,500 Boiler Upgrade Scheme. MCS membership is also the clearest competence signal for non-grant work.

How to compare quotes

Get at least three written quotes that include the survey method, cylinder size, radiator/underfloor plan, warranty length and aftercare. Be wary of anyone quoting without surveying your home.

Use the open directory

Our open installer directory lets you filter UK heat pump and renewable-heating companies by area and specialism — a useful shortlist alongside the MCS registry.

What it costs

Installed costs typically run £7,000–£13,000 before the grant. See our open benchmark dataset for current ranges and the heat pump vs gas calculator to model running costs.
