Disclaimer

Last updated: July 2026

Short version: this is an independent directory. We publish the SEAI register of registered contractors in a form that is easier to search, alongside general guidance on insulation and grants. We do not carry out insulation work, we do not vet the contractors listed, and we are not the SEAI. Anything on this site is general information to help you ask better questions, not advice about your own house.

We Are Not Affiliated with the SEAI

wallinsulationireland.ie is an independent website. It is not run by, endorsed by, or connected to the Sustainable Energy Authority of Ireland. Where we describe a grant scheme we are summarising SEAI's published rules in plain English. SEAI sets those rules, decides who qualifies and pays the grants, and its own guidance at seai.ie is the authority on all of it. If something here disagrees with SEAI, SEAI is right.

A Listing Is Not a Recommendation

The contractors on this site are taken from the SEAI public register of registered contractors. That register tells you a business has registered with SEAI to carry out grant-supported work of a given type. It is a useful starting point, and it is the reason we publish it.

It is not a review, a rating, a recommendation, or any form of vetting by us. We have not inspected these businesses, checked their insurance, visited their sites or assessed the quality of their work. Appearing on this site says nothing about a contractor beyond what the register says, and the order they appear in carries no meaning.

Choosing a contractor, agreeing a price and a specification, and satisfying yourself about insurance, references and guarantees is your decision. We are not a party to any contract you enter into, and we are not responsible for the work carried out, the conduct of any contractor, or any loss arising from either. If a business is listed in error or its details are wrong, tell us and we will correct or remove it, as set out in our privacy policy.

Grant Amounts

The grant figures on this site were last checked against SEAI's published amounts on 31 July 2026. We state them precisely because SEAI publishes them, and we date them because SEAI changes them. Amounts have changed more than once during 2026.

The home must have been built and occupied before 2011 for insulation and heating control grants. Heat pump and solar measures use a later date, so check the measure you want on seai.ie. The work must be carried out by an SEAI-registered contractor, who issues a post-works certificate. There is no income test on the Better Energy Homes grants. A homeowner on qualifying welfare payments may instead be eligible for the fully funded Warmer Homes scheme.

Whether your own home qualifies, and for how much, is decided by SEAI and not by us. The grant checker on this site is a rough guide built from the published amounts, not an application, an assessment or a promise of anything. Confirm your position with SEAI or with a registered contractor before you commit money to a job.

Cost Ranges

The prices on this site are indicative market ranges, published to help you judge whether a quote you have received is in the right general area. They are not quotes, estimates or offers, and nobody is bound by them.

What a job actually costs depends on the size and condition of the property, the state of the existing walls or render, access and scaffolding, the finish chosen and how exposed the site is. Two houses on the same street can differ. Get at least two quotes from SEAI-registered contractors and treat their figures, not ours, as the real ones.

Savings and Performance

You will not find a predicted annual saving on this site, and that is deliberate. Insulation reduces the heat escaping through the part of the building it covers, so a house currently losing a lot through that element has more to gain than one that is not. What that is worth on a bill depends on the construction and size of the house, the heating system, how the house is actually lived in, and the price of energy at the time.

Any specific figure attached to a house nobody has surveyed is guesswork, so we do not publish one. We also make no claim about what insulation will do to a BER rating, a property's resale value, or the mortgage products available to you. A contractor who has surveyed the property, or an SEAI energy assessment, is where a real number comes from. SEAI publishes its own national estimates if you want a benchmark.

VAT

Supply and installation of property insulation in a private dwelling is listed by Revenue at the reduced rate. The reduced rate is currently 13.5%, against a standard rate of 23%.

The rate depends on how the job is priced. Where the materials in a single supply come to more than two thirds of the total price, the standard rate can apply to the whole job instead. Ask any contractor to state on the quote which rate they have used and whether the price includes it.

This is general information, not tax advice. Revenue is the authority on VAT and its guidance at revenue.ie takes precedence over anything here.

Planning Permission and Protected Structures

External wall insulation changes the outside of a building, so it is not always exempt from planning permission. Protected structures and properties in architectural conservation areas are the common exceptions, and there are others. We describe the general position only. Your local authority decides, and confirming it is your responsibility and your contractor's, not ours.

General Guidance, Not Advice About Your House

Everything on this site is general information about insulation in Ireland. It is not professional, technical, financial or legal advice, and it is not specific to your property. Insulation done to the wrong specification for a building can cause problems, including damp, so decisions about your own house should rest on a survey by a competent person rather than on anything you read here.

We keep this site accurate and correct things when we find them wrong, but we do not warrant that all of it is complete or current at any moment, and we accept no liability for a decision taken on the basis of it. Links to other sites are for convenience and we are not responsible for their content.

Telling Us Something Is Wrong

If a figure here is out of date, a listing is incorrect, or something reads as misleading, we would rather know. Email dave@daveacoleman.com and we will check it against the source and fix it.
