HOW TO HIRE · TRADES & CONSTRUCTION · CHECKED OCTOBER 2026
A loft insulation in Ireland costs €400–€1,500 per job, typically around €800. Here is how to check that in a minute, what to ask before you book, and what you must be handed when the job is done.
THE 60-SECOND VERSION
BEFORE YOU BOOK
REGISTERED FOR WHAT, EXACTLY. Contractors may only carry out the measures they are registered for, so a contractor on the list for insulation is not thereby approved for a heat pump. A renewable installer registers with SEAI first and then adds heat pump or solar PV. For solar PV the INSTALLER applies to ESB Networks for the grid connection, not you. Registration is not a licence to trade — anyone may install insulation. It is MANDATORY TO GET THE GRANT, which is the practical constraint for almost every homeowner.
Search the SEAI Registered Contractor List for the name or the registration number before you agree a price. seai.ie →
Expect public liability; grant work also carries SEAI's own code of practice. From a company, ask for the insurer, the limit and the VAT number, and ask who actually attends: the team that turns up may be employed, subcontracted or both, and only one of those is supervised by the firm you are paying.
Ask to see the current certificate of insurance — the insurer's name, the limit and the date it runs to.
Under the Consumer Rights Act 2022 a trader must tell you they are a trader, and your consumer rights — work carried out with reasonable skill and care, and a cooling-off period on a contract agreed in your home or online — apply to traders and not to private sellers. On Locufy the trader status is shown on the profile.
Look for the trader badge on the Locufy profile, and ask anyone else for it in writing before you agree a price.
Providers on Locufy prove who they are with photo ID before they can be booked; the ID-checked badge shows who has done it, and the document itself is deleted once the check is made. For a loft insulation installer coming into your home it is the cheapest check there is.
Look for the ID-checked badge on the card, before you message anyone.
VAT at 13.5%, the reduced rate Revenue publishes for this service. Ask whether the price you were given includes it. A trader under the €42,500 registration threshold does not charge it; one over it must, and must show it separately.
Ask whether the figure you were given includes it, and for the VAT number if they are registered — Revenue publishes the rate for this service. revenue.ie →
A good answer: A number you can look up yourself before you agree a price — ventilation Considerations — proper ventilation is crucial when installing loft insulation to prevent moisture build-up.
A good answer: The quote rises step by step with the floor area. — ask before the quote rather than after.
A good answer: Materials are usually charged on top of the labour. — ask before the quote rather than after.
A good answer: The more decisions involved, the longer the job runs. — ask before the quote rather than after.
A good answer: Standard loft insulation services typically do not include structural repairs, electrical work, or the removal of existing insulation unless specified — get the exclusions named in the quote, because a loft insulation installer job is priced on what was agreed and not on what was assumed.
A good answer: Expect public liability; grant work also carries SEAI's own code of practice — installation Process — the installation process typically involves assessing the loft space, measuring the area, and applying the chosen insulation material.
A good answer: A written scope and a price before the loft insulation installer starts, and an itemised invoice after — types of Insulation Materials — loft insulation can be made from various materials such as fiberglass, mineral wool, or spray foam.
The figures are for the job, per job, and a quote for your own is the only number that binds anyone. Mineral wool insulation and Foam board insulation each carry their own band. Loft Insulation price guide →
