ESRI Says Retrofit Hassle Is High — Why Dublin Attic Insulation Is Still the Low-Disruption First Step

On 10 September 2026, The Irish Times reported ESRI research that should change how Dublin homeowners sequence a retrofit. Heat-pump knowledge is low — just 44 per cent of people could offer even basic information — and the “hassle factor” of disruption is high enough that national retrofit targets look at risk. That is not an argument against heat pumps. It is a practical reason to start with fabric work that does not empty your house: attic insulation.

What the ESRI actually found

Shane Timmons of the ESRI’s Behavioural Research Unit put more than a thousand people through exercises on switching from fossil heating. Fewer than half knew anything useful about heat pumps, even when the bar was as low as knowing they are routinely fitted in new homes. Separately, Prof John Curtis looked at disruption: 26 per cent intended to retrofit, 23 per cent had no interest because they did not want the mess, and 30 per cent said they were thinking about it but would be swayed by what the works entailed. Curtis said that mix will not deliver 500,000 homes to BER B2 by 2030 at the current pace. The same package of studies is summarised on the ESRI’s residential retrofit disruption bulletin, and the institute’s wider review of residential heat decarbonisation progress makes the same delivery shortfall clear.

National climate and energy policy still points at deep retrofit and heat-pump scale-up — that is the frame at the Department of Climate, Energy and the Environment. The behavioural evidence says many households will stall if the first ask is a high-disruption package they do not understand. So the useful Dublin question is not “heat pump or nothing.” It is “what low-disruption fabric step can you do while the bigger decision matures?”

Why attic insulation is the low-hassle first move

For a typical 1980s Dublin semi, or a redbrick terrace with a cold-roof loft, attic insulation is usually a one-day (or short multi-day) job: hatch open, joists quilted to modern depth, eaves air paths kept clear, hatch surround finished, cold-water tank jacketed if one still sits in the void. You keep living downstairs. There is no scaffolding wrap around the street elevation, no full heating-system rip-out, and no weeks of rooms off-limits. That is the opposite of the “whole property not suitable for use” end of the disruption spectrum the ESRI priced so heavily.

Attic insulation does not replace a heat pump when your plan eventually needs one. It is the fabric step that stops heat pouring through the ceiling while you learn what a heat pump actually is, what your BER path looks like, and whether walls or windows come next. Grid and meter questions for later electrification still sit with ESB Networks; they do not have to be solved on the same morning as the loft quilt. Irish newsrooms will keep covering the national numbers — see RTÉ News Ireland — but your hatch photo decides whether this week’s move is low or high hassle.

What “done” looks like on a Dublin loft day

Continuous depth on the joists. Clear eaves vents, not wool stuffed into the edge. An insulated, sealed hatch so you do not leave a cold picture-frame. If a cistern still lives in the roof void, jacket and lag it in the same visit so the new quilt is not undone — the same object we covered in why a naked attic tank undoes the quilt. That checklist is short on purpose. It is the kind of scope a hassle-sensitive household can say yes to without booking a week away from home.

SEAI attic grants are €1,100–€2,500 by dwelling type — confirm the live bands on SEAI’s attic insulation grant page. After-grant you-pay for a straightforward Dublin attic is typically €300–€1,500 on the personal quote. If SEAI does not approve, no work starts and you pay nothing under the grant guarantee. Broader scheme context for homeowners also sits on Citizens Information’s housing grants hub.

What to do this week

Read the Irish Times / ESRI piece once. Then open your hatch and photograph joist depth, eaves, hatch surround, and the tank if there is one. That photo set is the low-disruption brief.
