Wunergy

Air source heat pump installation from Birmingham

Wunergy is an MCS-certified installer of air source heat pumps working across Birmingham and the West Midlands. The company presents itself as a specialist in domestic heat pump systems, combining accredited installation with management of the Boiler Upgrade Scheme (BUS) grant on the customer's behalf. Its stated credentials include MCS certification, Gas Safe registration, F-Gas certification, RECC membership and Ofgem approval, alongside a Trustpilot rating badge.

The service is aimed at homeowners replacing gas or electric heating with a heat pump, and the company frames the offer around lower heating bills, access to the £7,500 BUS grant and reduced reliance on fossil fuels. Installation is described as tailored to each property and carried out to MCS standards.

Technical characteristics of the systems offered

Wunergy highlights several features of the heat pumps it installs, presented as reasons to choose the technology:

• High coefficient of performance (COP) with DC inverter technology, rated A+++ under the ErP energy-efficiency standard.
• Quiet operation, with noise levels as low as 42 dBA achieved through brushless DC inverter fans, dual shock-absorption mounting and multiple sound-insulation features.
• Wi-Fi control, using integrated CAREL and CGK control technology that allows several units to be managed from a single panel.
• PID intelligent defrost mode, which detects when defrosting is needed and switches over automatically.
• Heating capacities from 6 kW to 32 kW, with a DC inverter compressor that adjusts to outside temperature.

Two heat pump ranges for different homes

The catalogue distinguishes two models. The domestic air source heat pump is intended for everyday home heating, delivers water temperatures up to 60°C and operates in outdoor temperatures from –25°C to 45°C; it includes a built-in water pump and runs at noise levels between 42 dB and 45 dB. The cold-climate model uses Enhanced Vapour Injection (EVI) compressor technology and a high-efficiency refrigerant, and is designed to keep working in conditions down to –30°C.

Both are offered for properties ranging from compact terraces to large detached homes, with the company stating that it matches each household to a suitable system.

Boiler Upgrade Scheme handling

A central part of the service is the administration of the £7,500 Boiler Upgrade Scheme grant. As an MCS-certified installer, Wunergy applies on the customer's behalf, submits the documentation to Ofgem and deducts the grant directly from the quote, so the customer does not wait for reimbursement. The process is described in four stages: a free, no-obligation home survey; a fixed-price written quote with the grant already deducted; management of the application through to completion; and installation and commissioning by accredited engineers.

Installation is typically presented as taking two to three days, followed by a handover walkthrough of the system and ongoing support.

Indicative costs after the grant

The website sets out typical installation prices once the £7,500 BUS grant has been applied, depending on property size and system:

• Small property (1–2 bedroom flat or terrace, 6–8 kW heat pump, hot water cylinder included): £2,500–£4,500.
• Medium property (3 bedroom semi-detached, 8–12 kW heat pump, radiator upgrades if needed, smart controls included): £4,500–£7,500.
• Large property (4+ bedroom detached home, 12–32 kW heat pump, buffer tank and cylinder, underfloor heating compatible): £7,500–£12,000.

These figures are presented as indicative examples for typical installations rather than fixed prices.

Coverage across the West Midlands

Beyond Birmingham, the company lists Worcester, Evesham, Stratford-upon-Avon, Bromsgrove, Redditch and Coldfield among its locations. The site also refers to customers in Solihull, Sutton Coldfield and Edgbaston, Birmingham, in the reviews it publishes, which describe lower heating bills, quiet operation and the handling of the grant application.

Additional offer for existing heat pump owners

Wunergy also mentions a tariff for households that already have a heat pump, presented as a way to lower energy bills through twice-daily discounts.
