How do you choose a Heat Pumps installer in Merthyr Tydfil?
Check MCS Certification
Only MCS-certified installers qualify you for the Boiler Upgrade Scheme grant of up to £7,500. Verify your installer on the MCS register. 21 installers serving Merthyr Tydfil are currently certified.
Get a Heat Loss Survey
A proper installer will survey your home and carry out a heat loss calculation before recommending a system size. This determines the kW capacity needed. Be wary of quotes given without a home visit in Merthyr Tydfil.
Compare Brands & SCOP Ratings
Ask which brand and model is being quoted. Look for a SCOP rating of 3.5+ for air-to-water systems. Daikin, Mitsubishi Electric, Samsung, and Grant are the most common brands used by UK installers.
Check Insulation Requirements
Heat pumps need a well-insulated home (EPC C or better). Ask the installer whether your current insulation is adequate or if upgrades are needed first. Separate insulation grants may be available through ECO4 or the Great British Insulation Scheme.
Verify Warranties
Heat pump manufacturers typically offer 5–7 year product warranties. Ask about the installer’s workmanship warranty (minimum 2 years). Some brands like Daikin offer extended warranties up to 10 years when installed by an accredited partner.
Ask About Running Costs
A good installer will estimate your annual running costs compared to your current heating system (oil, gas, or solid fuel). With a SCOP of 3.5, a heat pump uses roughly one-third the energy of a direct electric heater for the same heat output.

Frequently Asked Questions About Heat Pump Installers in Merthyr Tydfil
How do I find a good heat pump installer in Merthyr Tydfil?
Check that the installer is MCS certified, as this is required to claim the Boiler Upgrade Scheme grant of up to £7,500. A good installer will carry out a full heat loss calculation for your home before recommending a system size. Compare at least 2–3 quotes from installers in Merthyr Tydfil, ask for references, and verify they carry public liability insurance. Look for experience with the specific brand they’re quoting.
How much do heat pump installers in Merthyr Tydfil charge?
A typical air-to-water heat pump installation in Merthyr Tydfil costs £8,000–£14,000 before the Boiler Upgrade Scheme grant. The grant provides up to £7,500, which can bring the net cost down to as low as £500–£6,500. Prices vary based on the heat pump brand (Daikin and Mitsubishi are most common), system capacity, whether you need a new hot water cylinder, and the complexity of the pipework. Ground source systems are more expensive at £12,000–£20,000.
Are heat pump installers in Merthyr Tydfil MCS certified?
Not all heat pump installers are MCS certified. You must use an MCS-certified installer to qualify for the Boiler Upgrade Scheme grant of up to £7,500. MCS maintains a public register at mcscertified.com. On this page, 21 of the 21 listed installers are MCS certified. Look for the “MCS Certified” badge on each listing.
How long does heat pump installation take?
A typical air-to-water heat pump installation takes 2–3 days. If the existing radiators need upgrading or underfloor heating is being added, it may take longer. The full process from initial survey to completed installation is usually 6–12 weeks, including the heat loss survey, Boiler Upgrade Scheme application, equipment ordering, and installation scheduling.
Do I need to upgrade my insulation before getting a heat pump?
It is recommended your home has an EPC rating of C or better before installing a heat pump. Heat pumps operate at lower flow temperatures than oil or gas boilers, so good insulation is essential for them to work efficiently. Your installer should carry out a heat loss calculation — if your home loses too much heat, they may recommend loft, cavity wall, or external insulation first. Separate grants may be available through schemes such as ECO4 or the Great British Insulation Scheme.
