Heat Pump Suitability for West Mayo Homes
Heat pumps are an increasingly popular choice for homeowners across West Mayo looking to reduce energy bills and qualify for SEAI Better Energy Homes grants. However, a heat pump is not suitable for every property — correct installation depends on the building fabric being adequately insulated to allow the system to operate efficiently.
At Homecert, we carry out independent, engineering-led technical assessments to determine whether your home is a genuine candidate for a heat pump — and if not, what fabric upgrades would need to happen first. This protects you from costly installations that underperform.
Our assessments are produced to SEAI standards and can be submitted directly as part of a grant application.
What We Assess
What's Included in a Heat Pump Assessment
Heat Loss Calculations
We calculate the full heat loss of your property room-by-room using CIBSE/BSRIA-recognised methodology. This determines the correct heat pump sizing and output required for your home.
Fabric First Principle
Before recommending a heat pump, we assess the building fabric — walls, roof, floors and windows — to ensure heat is retained effectively. We identify any upgrades needed to make installation viable.
SEAI Pre-Grant Report
We produce a technical suitability report in the format required by SEAI for Better Energy Homes and One Stop Shop grant applications. This report is submitted with your application.
System Sizing Guidance
Based on heat loss figures, we provide guidance on the appropriate heat pump capacity and emitter configuration — whether radiators, underfloor heating or a hybrid system.
Running Cost Modelling
We model estimated running costs for a correctly sized heat pump versus your current heating system, so you can make an informed decision about the investment.
Written Technical Report
All findings are presented in a written technical report you can share with your installer, grant authority or solicitor. Clear, professional documentation.
The Fabric First Principle
Why Insulation Matters Before Heat Pump Installation
A heat pump operates most efficiently when producing lower flow temperatures — typically 35–45°C, compared to 70–80°C from a conventional boiler. This means your home must retain heat well enough that these lower temperatures are sufficient. If the fabric is poorly insulated, the heat pump runs continuously, your energy bills increase and the system may struggle to maintain comfortable temperatures during cold Atlantic winters in West Mayo.
We assess and, where necessary, recommend improvements to the following before declaring a property heat pump ready:
- ✓External or internal wall insulation (U-value ≤0.35 W/m²K)
- ✓Attic/roof insulation to current standards
- ✓Floor insulation where accessible
- ✓Window and door air tightness
- ✓Controlled ventilation strategy
- ✓Thermal bridging mitigation at junctions
FAQ
Heat Pump Assessment Questions
Yes. SEAI requires a technical assessment from a registered assessor as part of the Better Energy Homes heat pump grant application. The report confirms the property is suitable and the proposed system has been correctly sized. Without this documentation, your grant application will not be processed.
Many older West Mayo homes — including cavity wall and solid wall construction built before 1980 — can be made heat pump ready with targeted fabric upgrades. External wall insulation is often the most impactful intervention. We assess each property on its merits and advise honestly on what is required.
Heat pump technical assessments are priced from €250 for standard residential properties in West Mayo. The assessment includes on-site heat loss survey, calculations and written technical report. Use our instant quote tool or call 087 752 6652 for a precise quote.
We operate independently of installers to ensure our assessments remain objective. We can provide you with the technical specification your installer will need. We recommend using an SEAI-registered installer from the SEAI contractor list for grant eligibility.
