EPC Improvements Ltd

EPC Improvements Ltd is a Chelmsford-based renewable energy installer specialising in heat pump and solar PV systems for residential and commercial properties across Essex and the wider South East of England. The company holds both MCS certification and TrustMark accreditation, and has completed over 1,500 installations since its founding in 2016.

Operating with a design-led approach, EPC Improvements focuses on delivering whole-system renewable energy solutions that reduce running costs and carbon emissions. Rather than adopting a sales-driven model, the company emphasises technical consultation, clear advice, and long-term system performance to guide clients towards the most suitable solution for their property.

The company's installed base collectively produces approximately 4.3 GWh of energy annually whilst reducing around 2,200 tonnes of CO₂ equivalent emissions each year — figures that reflect a substantive and growing presence within the UK's renewable energy transition.

Services

EPC Improvements offers a comprehensive range of renewable energy and energy-efficiency installations, handling design, supply, and installation across all of its core technology areas. Post-installation support and maintenance are also provided as part of the company's long-term service commitment.

• Air source heat pumps: Design and installation of air source heat pump systems for residential and commercial properties, sourcing equipment from manufacturers including Mitsubishi, Vaillant, Viessmann, and Stiebel Eltron.
• Ground source heat pumps: Ground source heat pump installations for properties where ground loop or borehole systems are suitable, delivering efficient low-carbon heating solutions.
• Solar PV panels: Supply and installation of solar photovoltaic systems for homes, commercial buildings, and new-build developments, designed to reduce grid energy dependency.
• Battery storage: Integration of battery storage systems including Tesla Powerwall, SolarEdge, and GivEnergy products, allowing clients to store and maximise their solar-generated energy.
• Underfloor heating: Installation of underfloor heating systems, frequently paired with heat pump installations to optimise system efficiency.
• Mechanical ventilation with heat recovery (MVHR): MVHR system installations to improve indoor air quality and energy efficiency, particularly suited to well-insulated new-build and retrofit projects.
• Air conditioning: Supply and installation of air conditioning systems for residential and commercial applications.
• EV charging: Electric vehicle charging point installations for homes and commercial premises.

Accreditations

EPC Improvements holds MCS (Microgeneration Certification Scheme) certification for solar panel installation, air source heat pump installation, and ground source heat pump installation. The company is also TrustMark accredited, demonstrating compliance with government-endorsed quality and consumer protection standards.

These accreditations are a requirement for customers wishing to access government funding schemes such as the Boiler Upgrade Scheme (BUS), which currently offers grants of up to £7,500 towards the cost of a qualifying heat pump installation. EPC Improvements assists clients in navigating available funding to reduce upfront installation costs.

Pricing

Pricing for heat pump and solar PV installations varies depending on the technology selected, the size and type of property, system complexity, and any additional products such as battery storage or underfloor heating. Ground source heat pump installations typically carry higher costs than air source systems due to groundwork requirements. As an MCS-certified installer, EPC Improvements is able to facilitate access to the Boiler Upgrade Scheme grant, which can significantly offset the cost of heat pump installations for eligible customers. Prospective clients are encouraged to contact the company directly for a tailored system design and quotation.
