Services
Energy Assessments
We conduct detailed energy performance assessments for residential and commercial properties, including SAP calculations and EPC ratings. Our evaluations identify cost-effective improvements to enhance energy efficiency, reduce carbon emissions, and comply with regulatory standards while maximising property value.
Thermal Surveys
Using thermal imaging technology, we detect heat loss and air leakage points in building envelopes. Our surveys pinpoint insulation gaps, thermal bridging, and ventilation issues, enabling targeted upgrades that improve thermal comfort and reduce heating costs by up to 30%.
Ventilation Solutions
We design mechanical ventilation systems that maintain optimal indoor air quality while preventing heat loss. Our solutions address condensation risks and CO2 buildup, reducing health hazards and improving productivity in residential and commercial environments through balanced airflow management.
Retrofit Design
Our retrofit strategies integrate insulation, air sealing, and renewable energy systems to modernise existing structures. We provide phased implementation plans that prioritise high-impact improvements like cavity wall insulation and boiler replacements, achieving energy bill reductions of up to 2,500 annually.
Sustainability Consultancy
We advise on sustainable construction practices and low-carbon technologies, including photovoltaic panels and low-energy lighting. Our consultancy covers grant eligibility for energy upgrades and long-term cost-benefit analysis to support environmentally responsible building operations.

Questions
What energy efficiency grants are available for homeowners?
Grants of £400–£1,000 are available for boiler replacements through the Housing Executive. We can advise on eligibility criteria and application processes for energy-saving upgrades.
How can ventilation improve indoor air quality?
Mechanical ventilation systems reduce CO2 levels and moisture buildup, cutting cold transmission risks by 40% and improving cognitive performance. We design systems that maintain air quality without compromising thermal efficiency.
What payback periods can I expect from energy upgrades?
Insulation and air sealing typically pay back within 2–5 years. Photovoltaic panels offer 8-year returns, while boiler replacements save £210–£500 annually, with grants covering up to 60% of installation costs.
How do energy efficiency improvements affect property value?
Upgrades like cavity wall insulation and EPC improvements can increase property values by £10,000+ while reducing annual energy bills by up to £2,576 through enhanced thermal performance and modernised systems.
What building types do you specialise in?
We work on residential properties including 1930s terraced houses, 1960s semi-detached homes, and commercial buildings, providing tailored retrofit solutions that address unique thermal performance challenges in each structure.
