Services
MVHR Design
Our mechanical ventilation with heat recovery design ensures continuous fresh air supply while retaining 90% of heat energy. We create custom solutions for residential and commercial properties that meet Building Regulations Part F requirements. Our systems eliminate condensation, reduce allergens, and maintain optimal indoor air quality through advanced filtration technology.
Passivhaus Consultancy
We provide specialist guidance for achieving Passivhaus certification through thermal bridging analysis and airtightness strategy development. Our consultants help architects and self-builders meet rigorous energy efficiency targets while maintaining architectural integrity. Services include U-value calculations and thermal performance optimisation for new builds and renovations.
Solar Panels
Our high-efficiency photovoltaic systems convert sunlight into electricity with minimal grid dependency. We offer tailored solar solutions that integrate with battery storage and heat pump systems to maximise energy self-sufficiency. All installations comply with MCS certification standards and include performance monitoring options for residential and commercial properties.
Triple-Glazed Windows
Precision-engineered window systems featuring argon-filled chambers and low-E glass coatings achieve U-values as low as 0.8 W/mK. Our windows enhance thermal performance while maintaining acoustic insulation and security standards. Available in timber, aluminium, and composite finishes to suit modern and traditional architectural styles.
Heat Pumps
We supply and install air source and ground source heat pumps that deliver up to 400% efficiency by transferring ambient heat into buildings. Our systems include weather-compensating controls and integrate with underfloor heating for consistent temperature regulation. All installations meet MCS certification requirements for renewable heat incentives.
