Engineering Expertise for Guernsey’s Energy Transition
Independent engineering advisory supporting Guernsey’s transition to low-carbon heating, industrial efficiency, and resilient energy systems.
Why Guernsey Requires Engineering Expertise
Guernsey’s properties present unique technical challenges — granite construction, exposed coastal conditions, rising electricity costs, and increasing adoption of heat pump systems.
iSolutions delivers independent, high-level thermal engineering advisory to homeowners, developers, architects, commercial operators and installers seeking performance, reliability and long-term efficiency.
Independent Heat Pump Advisory
Heat pump systems must be correctly sized, specified and controlled to deliver expected seasonal performance. Poor early-stage engineering decisions frequently result in high operating costs, reduced efficiency and long-term underperformance.
Engineering support includes:
- Retrofit feasibility assessments
- Independent heating load verification
- Seasonal COP and performance validation
- Control strategy review and optimisation
- Low-GWP refrigerant advisory
- Pre-installation design review
Suitable for:
- Homeowners planning upgrades
- Developers prior to equipment commitment
- Installers seeking technical validation
- Property managers addressing performance concerns
Granite & Retrofit Building Assessment
Many Guernsey properties are constructed with thick granite walls and traditional building methods. Thermal upgrades must be engineered carefully to avoid condensation risk, emitter mismatch and system inefficiency.
Advisory scope includes:
- Thermal performance assessment of existing buildings
- Emitter suitability evaluation (radiators / underfloor heating)
- Domestic hot water optimisation
- Retrofit heating strategy development
- Low-carbon upgrade roadmapping
- Insulation strategy considerations (internal vs external approaches)
Developer & Architect Technical Advisory
Early-stage engineering decisions determine long-term performance, cost exposure and operational reliability.
Independent technical input at planning and design stages reduces risk before procurement and installation.
Support includes:
- Heating system specification review at planning stage
- Mechanical design validation
- Risk identification prior to procurement
- Pool heating integration strategy
- Independent second-opinion engineering reports
- Value engineering without compromising performance
Applicable to:
- High-end residential developments
- Refurbishment and retrofit projects
- Hospitality and mixed-use schemes
Commercial & Hospitality Energy Optimisation
Hotels, leisure facilities, care homes and commercial buildings frequently operate heating systems below achievable efficiency levels.
Independent engineering review identifies performance gaps and practical optimisation pathways.
Focus areas include:
- HVAC performance audits
- Energy cost reduction strategy
- Heat recovery feasibility assessment
- System optimisation with short ROI focus
- Plant upgrade advisory during refurbishment
- Independent technical evaluation of contractor proposals
Specialist Pool Heating Advisory
Swimming pool heating systems require careful thermodynamic and hydraulic design to operate efficiently, particularly when using modern low-GWP refrigerants.
With direct experience designing pool heat pump systems and heat exchangers, advisory covers:
Support includes:
- Pool heat pump sizing verification
- Seasonal running cost modelling
- Hydraulic and heat exchanger optimisation
- Pool heating integration strategy
- Performance troubleshooting
- Upgrade and replacement strategy
Dispute & Independent Technical Review
Where system performance does not meet expectation, objective engineering assessment becomes critical.
Independent review may include:
- Technical performance reporting
- Warranty performance validation
- Installation and design review
- Support in technical or insurance disputes
