Services
Energy Assessments
We conduct comprehensive energy performance evaluations for residential properties using SAP software and thermal imaging technology. Our assessments identify cost-effective improvements that typically save homeowners 500 annually with 2-year payback periods. Our certified assessors provide detailed reports with prioritised recommendations for enhancing energy efficiency in both new and existing dwellings.
Thermal Surveys
Our thermal imaging surveys detect hidden heat loss and air leakage points in building envelopes. Using specialist infrared cameras, we identify insulation gaps and thermal bridging issues that contribute to energy waste. This non-invasive diagnostic tool helps homeowners visualise heat patterns and target remedial work where it will have maximum impact on energy bills and comfort levels.
Ventilation Solutions
We design and implement mechanical ventilation systems that maintain healthy indoor air quality while reducing energy consumption. Our solutions address CO2 build-up and dampness issues in modern airtight homes, improving occupant health and productivity. We specialise in whole-house ventilation strategies that comply with current building regulations while minimising heat loss.
Building Inspections
Our detailed building inspections assess structural integrity and energy performance of residential properties. We examine construction materials, insulation levels, and thermal performance characteristics across different property types including 1930s terraces and 1990s semi-detached homes. Our reports highlight maintenance requirements and energy-saving opportunities tailored to each property's specific characteristics.
Sustainability Consultancy
We provide expert guidance on achieving sustainable building standards including Code for Sustainable Homes requirements. Our consultancy covers renewable energy integration, low-carbon heating systems, and eco-friendly construction materials. We help homeowners navigate grant schemes for boiler replacements and energy efficiency improvements while ensuring compliance with current environmental regulations.
