Your priorities come first.
We begin with the cold rooms, existing upgrades and changes you want to make. The professional assessment establishes the starting condition and tests the options against your budget and comfort goals.
FENNOR / WHOLE-HOME RETROFIT
One connected plan.
A more comfortable home.
A whole-home upgrade brings warmth, fresh air and heating into one plan. Fennor helps you see the full picture, choose priorities and understand how the work will fit around your life.
YOUR UPGRADE WITH FENNOR
Sequence is
part of the design.
Fennor turns the assessment findings and your daily routine into a proposed sequence. You can see when rooms or services would be affected, which decisions come first and what the next stage delivers.
Plan your retrofit with FennorYour concerns, budget and plans come first.
Tell us what a better home means to you.
Fennor turns your comfort concerns, budget and previous upgrades into a brief. We explain which survey answers the remaining questions, including any moisture, structural or services investigation, before presenting a firm proposal.
What becomes clear
Your brief, available BER/advisory report and relevant survey findings.
This is an outline of the conversation and project stages. Your home, design and agreed delivery contract determine the actual order, duration and responsibilities.
WHERE THE DISCIPLINES MEET
Good details.
Clear handovers.
We bring the design and installation responsibilities for the joins into the proposal. You know who handles each part and when it is inspected, instead of having to resolve a gap between trades during the work.
Windows × insulation
Reveal depth, sill projection, airtightness and the intended line of insulation.
Airtightness × ventilation
Purpose-provided air paths and a ventilation strategy suited to the improved home.
Fabric × heating
Room heat losses and emitters assessed against the agreed post-upgrade specification.
Construction × evidence
Photographs, product records and inspection points captured before work is concealed.
ONE BRIEF, EVEN WHEN PHASED
Today’s work.
Tomorrow’s options.
If the upgrade needs to happen in stages, we show what each phase delivers and where provision for later work belongs. Future floor levels, window positions and service routes are considered before the first phase is agreed. The image is not a construction specification; your installation details follow the assessment of your home.

A better-feeling home.
One joined-up plan.
Look inside an illustrative home to see how the upgrades connect. Fennor explains the assessed options and their effects on your rooms before the work is agreed.

EXPLORE YOUR UPGRADE
A more comfortable home
A warmer home starts with its shell.
The roof, walls and floor form a connected layer around your rooms. Suitable insulation helps retain warmth, but the existing construction and any damp issues need assessment before an upgrade is chosen.
YOUR FENNOR JOURNEY
Fennor turns the assessment findings into insulation options for your home, explaining preparation, repairs and the finishes affected before you choose the work.
YOUR PROJECT WITH FENNOR
One home.
Improvements that work together.
We explain the choices, the work involved and what happens next, so you can decide with a clearer picture.
We connect the work between rooms and trades.
Window edges, wall insulation and roof junctions need to work together. We identify the required design input and explain the order of work, including access and whether you will need temporary accommodation.
A home you understand at handover.
Before work is agreed, we set out the inspections, commissioning and post-works assessment included. We also explain who will demonstrate the controls, provide maintenance guidance and deal with any remaining items.

Reviewed · Guidance, not an eligibility decision.
Grant support
Heat-pump system for your home
Up to €14,500
The eligible house maximum includes the system, necessary heating upgrades and qualifying scrappage. It is not a flat payment for every installation.
Conditions & official guidance+
- Heat-pump system — house
- Up to €10,500
- Necessary central-heating upgrades — house
- Up to €2,000
- Qualifying scrappage
- €2,000
- Combined apartment maximum
- Up to €11,500
- Home built and occupied before 2021, with an MPRN. Applies to eligible air-to-water, ground-source, exhaust-air-to-water and water-to-water systems; air-to-air has a different ceiling.
- Scrappage covers qualifying oil, gas, solid-fuel or electric-storage heating replacement; SEAI also includes eligible homes without central heating. The installation design determines each component.
- Grant approval must precede work. Payment cannot exceed eligible cost; a post-works BER and completion documents are required. Existing-heat-pump replacement follows a separate route.
Grant support
Attic insulation
Up to €2,000
Standard grants vary by home type. Certain households can receive the enhanced rate below instead.
Conditions & official guidance+
- Detached
- €2,000
- Semi-detached / end-terrace
- €1,500
- Mid-terrace
- €1,400
- Apartment
- €1,100
- Home built and occupied before 2011; no previous attic grant. The appropriate roof area, ventilation and installation standard must be addressed.
- The apartment rate depends on eligible exposed roof area. This individual grant is for qualifying attic insulation; it does not turn roof or attic-conversion work into grant-funded work.
Grant support
Enhanced attic insulation
Up to €2,500
Higher attic support for qualifying welfare recipients, eligible HAP/RAS homes and qualifying first-time buyers of existing homes.
Conditions & official guidance+
- Detached
- €2,500
- Semi-detached / end-terrace
- €1,900
- Mid-terrace
- €1,800
- Apartment
- €1,400
- First-time-buyer eligibility relates to qualifying existing-home purchases from 1 January 2025; evidence is required. Other enhanced routes have their own welfare or tenancy conditions.
- This replaces the standard attic amount; it is not a second payment. The pre-2011 home and previous-funding rules still apply.
Grant support
Cavity-wall insulation
Up to €1,800
Standard support depends on dwelling type and whether the walls are suitable for a complete cavity-insulation solution.
Conditions & official guidance+
- Detached
- €1,800
- Semi-detached / end-terrace
- €1,300
- Mid-terrace
- €850
- Apartment
- €700
- Home built and occupied before 2011. Required whole-surface coverage, construction suitability and moisture checks apply.
- Previous wall support affects the permitted next measure. Traditionally constructed homes are excluded from this individual scheme; we assess suitable non-grant improvement work separately.
Grant support
Enhanced cavity-wall insulation
Up to €2,300
Higher cavity rates for qualifying welfare and eligible HAP/RAS households. First-time-buyer status alone does not establish this entitlement.
Conditions & official guidance+
- Detached
- €2,300
- Semi-detached / end-terrace
- €1,700
- Mid-terrace
- €1,100
- Apartment
- €900
- This replaces, rather than supplements, the standard cavity grant. Household evidence and the pre-2011 property conditions apply.
- Your walls must meet the scheme’s technical requirements; this is not funding for unsuitable traditional construction.
Grant support
Internal wall insulation
Up to €4,500
Support towards a qualifying complete internal-wall upgrade, with room space, junctions and moisture considered before the work.
Conditions & official guidance+
- Detached
- €4,500
- Semi-detached / end-terrace
- €3,500
- Mid-terrace
- €2,000
- Apartment
- €1,500
- Home built and occupied before 2011. Traditionally constructed homes are excluded from this individual wall scheme.
- A previous cavity grant may permit a subsequent internal upgrade under current rules. Prior internal or external funding changes eligibility; the same measure is not simply funded twice.
Grant support
External wall insulation
Up to €8,000
The largest individual wall-insulation ceiling applies to detached homes, with different rates for other dwelling types.
Conditions & official guidance+
- Detached
- €8,000
- Semi-detached / end-terrace
- €6,000
- Mid-terrace
- €3,500
- Apartment
- €3,000
- Home built and occupied before 2011. A suitable whole-surface solution and appropriate junction, moisture and ventilation details are required.
- Previous cavity or internal funding may permit a later external measure; previous external funding does not permit a further wall grant. Traditionally constructed homes are excluded from this individual scheme.
Grant support
Energy-efficient replacement windows
Up to €4,000
Support depends on your dwelling type, the existing windows and the home’s insulation performance—not just the specification of the new glass.
Conditions & official guidance+
- Detached
- €4,000
- Semi-detached / end-terrace
- €3,000
- Mid-terrace
- €1,800
- Apartment
- €1,500
- Home built and occupied before 2011. Required performance is post-works HLI at or below 2.3, or attic and walls assessed Good or Very Good, alongside scheme window standards.
- You do not necessarily have to replace every window, but the grant is paid once per property. Ventilation and escape requirements still apply.
- For a new project, secure approval before ordering or starting. If work was already ordered or started, ask about SEAI’s specific transitional provisions rather than assuming eligibility.
Grant support
Energy-efficient external doors
Up to €1,600
€800 per eligible external replacement door, up to two doors, subject to the property and performance requirements.
Conditions & official guidance+
- The pre-2011 home, insulation/heat-loss, compliant door-performance and post-works BER conditions apply.
- Not a grant for ordinary internal doors or every new opening in an extension. We explain the proposed eligible replacements before you order.
Grant support
Heating controls
€700
Support to improve control of an existing heating system. A separate €50 contribution towards the required post-works BER may also apply.
Conditions & official guidance+
- Home built and occupied before 2011, with a valid MPRN. Approval must precede work and the eligible controls upgrade must be completed by a contractor registered with SEAI for this measure.
- Not available if you are applying for, or have already received, a heat-pump-system grant. Fennor confirms the registered delivery role before presenting this support as part of your proposal.
Grant support
Post-works BER support
€50 standard support
A contribution towards the required post-works BER for applicable individual-grant upgrades. Qualifying welfare applicants may receive €280 instead.
Conditions & official guidance+
- Support is tied to the eligible grant works and required assessment; it is not a general payment for obtaining any BER.
- The enhanced €280 route has separate welfare and application conditions. We explain the assessment cost and which support applies without adding both rates.
USEFUL ANSWERS
A whole-home project.
Your questions, answered.
Plain language. No pressure to have it all figured out.
01Can Fennor coordinate several improvements in one plan?
+
Yes. We connect insulation, ventilation, windows and heating in a sensible sequence, including work that can be phased. Your proposal identifies the work Fennor can cover, the individual-grant conditions to check and any specialist assessment or registered role required.
02Can we agree a target BER?
+
Yes. We put your target into the assessment and explain what the proposed work is expected to achieve. The final rating depends on completed work, supporting information and the assessor’s calculation.
