About one in ten Irish households gets its drinking water from a private well. If yours fails a lab test, or the well can’t keep up with the house, your county council can pay part of the cost of fixing it. The rates haven’t changed since 2020, but the rules are strict, and the one that catches most people out is starting work too early. Here’s how much you can get in 2026, who qualifies and how to apply.
Quick answer
- Water treatment: 100% of the approved cost, up to €1,000
- Fixing an existing well: 85% of the approved cost, up to €3,000
- A new well: 85% of the approved cost, up to €5,000
- Minimum: the works must cost at least €750 in total, or no grant is paid
- Golden rule: don’t start any works until the council has inspected the well and approved the job in writing
How much is the private well grant in 2026?
The grant is set by the Housing (Private Water Supply Financial Assistance) Regulations 2020 (S.I. 192 of 2020). The Irish Statute Book lists them as unchanged, and Citizens Information showed the same figures in August 2026.
| Type of work | Grant | Maximum |
|---|---|---|
| Water treatment (for example filtration or UV) | 100% of approved cost | €1,000 |
| Well rehabilitation (for example deepening or relining the bore, or clearing silt) | 85% of approved cost | €3,000 |
| New well (where the council agrees it’s the best solution) | 85% of approved cost | €5,000 |
You can claim treatment on its own, or treatment together with either a rehabilitation or a new well. You can’t claim both the €3,000 and the €5,000. The approved cost is whichever is lower: the council’s estimate of a reasonable price, or what the job actually cost.
Heard the grant went up in 2023? That was the septic tank grant, which rose from €5,000 to a maximum of €12,000. The private well grant was not increased.
Who qualifies for the well grant?
Under the regulations and the Department’s national terms and conditions, all of these must apply:
- The house has been fully built for more than seven years.
- It’s the applicant’s normal home. Long-term rentals count. Holiday homes, short-term lets, self-catering properties, caravans and mobile homes don’t, and nor do houses owned by councils, housing associations or the HSE.
- There’s no public main or group scheme available. The house must not be connected to, or able to reasonably connect to, Uisce Éireann or a group water scheme, and the area must not be about to be served by either.
- The well serves one house only. A shared source feeding several houses doesn’t count.
- There’s a real problem. The water isn’t wholesome and clean, or there isn’t enough of it for the household’s domestic needs.
- No grant in the last seven years. No water supply grant, including a treatment grant, can have been paid for the house in the previous seven years.
There is one exception to the seven-year rule. If you didn’t use the full grant the first time and something unforeseen happens, such as contamination, subsidence or weather damage, the council can allow a second application. The two payments together can’t go over €3,000 for rehabilitation or €5,000 for a new well.
What the grant covers, and what it doesn’t
Qualifying works include a new or rehabilitated well, a pump house, pipes, pumps and electrics for the supply, treatment equipment, and the lab testing before and after the works. Testing only counts once the works are complete. The Minister confirmed in December 2023 that testing on its own isn’t funded.
The grant does not cover:
- Water softeners. Hardness isn’t treated as a water quality problem for the grant, and systems to remove sodium from softened water are excluded too
- Plumbing inside the house
- Water for a farm or business. The council may approve only the domestic share of the cost
- Treatment beyond what’s needed to make the water wholesome and clean
- Anything started before approval
The €1,000 is for treatment the council agrees is needed to bring the water up to drinking water standards, such as UV for bacteria. Whether a particular system qualifies is the council’s call, made from the lab report and its inspection.
Don’t start any work before written approval. Works that begin before the council’s on-site inspection and written approval don’t qualify, and the claim will be refused. Asked in the Dáil in July 2026 whether emergency works could be paid for afterwards, the Minister’s answer was no: grant aid is not available where works began before approval. If the well is contaminated while you wait, the EPA advises boiling drinking water until you’re sure it’s safe.
Water testing for the grant
You need two lab tests: one before the works, to show what equipment the water needs, and one after, to prove the treated water passes.
- An accredited lab. The lab must be independent and INAB accredited (or equivalent). Results from non-accredited labs aren’t accepted.
- The lab takes the sample, not you. A kit you fill yourself won’t count. In some areas the council or the HSE can arrange sampling.
- Your council sets the list. Each council gives you the bacteria and chemical checks to run for local conditions.
- Run the system first. The terms advise using the new treatment for at least two weeks before the after test.
- No pass, no payment. The council won’t pay without a satisfactory Certificate of Analysis. If the after test fails, you retest, with more work if needed, until it passes.

How to apply for the private well grant, step by step
- Get the water tested. Book an accredited lab to take a sample and test for your council’s list. The report shows what’s wrong, so the installers quoting can specify the right equipment.
- Get three quotes. You need three quotes for all the proposed works, including treatment, and a copy of a current Revenue tax clearance certificate for each contractor.
- Fill in Form PWS 1a. Get it from your council’s website or its Rural Water Liaison Officer. It asks for the age of the house, what’s wrong with the supply, the works and their cost, and any grant paid in the last seven years. Send it with the quotes and tax clearance certificates.
- Wait for the inspection. The council inspects the supply to confirm the problem, decide whether the proposed works qualify and are the most suitable, and give advice.
- Get written approval. The council tells you by letter or email whether the application is eligible. Only the approved works will be paid for.
- Have the work done, then test again. Run the system for at least two weeks, then have the lab take the after sample.
- Claim with Form PWS 1b. Include itemised receipts from every contractor, the after Certificate of Analysis, your PPSN and, for a new or rehabilitated well, the driller’s signed Certificate of Water Quantity from a pumping test.
- Post-works inspection and payment. The council checks the works are complete and the supply is satisfactory, then pays. If the job cost less than approved, it pays on the lower figure.
There’s no fixed processing time: the national terms say only as quickly as possible. If you’re refused, you can appeal in writing within three weeks of the decision.
Some councils add their own rules
Councils run the scheme, and several add local requirements:
| Council | Local rule |
|---|---|
| Carlow | The sample must be taken at the kitchen sink tap, by someone trained in drinking water sampling |
| Wexford | The grant isn’t processed until all works have been paid for in full and receipts for those payments have been provided |
| Kildare | Its test list (revised February 2024) has 16 checks, including E. coli, nitrate, iron, manganese and lead |
| Cavan | The lab must be accredited for every check except odour and taste |
Check your council’s well grant page before booking the lab, so the first test covers the right list.
How we help
We don’t test water ourselves. An independent, INAB-accredited lab does that. Send us the lab report and we’ll read it, specify the treatment that fixes what it shows, and give you an itemised quote to submit with your application. We fit only after your council has approved the job in writing.
If the water is also hard, we’ll price a water softener separately, as the grant won’t cover it. See our well water treatment page for the systems we fit, and our guide to bacteria in well water if your report shows E. coli.
Applying for the well grant?
Send us your lab report and we’ll give you an itemised quote for your application. We fit only once your council has approved it, nationwide except Donegal, Kerry, Leitrim and Sligo.

Common questions
Is the treatment grant still €1,000 in 2026?
Yes. It’s 100% of the approved cost up to €1,000, unchanged since the 2020 regulations. The bigger 2023 increase was for septic tanks.
Can I get the well grant for a water softener?
No. Hard water isn’t treated as a quality problem for the grant, so softeners, and sodium removal after a softener, are excluded.
I had to fix my well in an emergency. Can I claim afterwards?
No. Answering a Dáil question about emergency works in July 2026, the Minister confirmed the grant isn’t available where works began before council approval. Contact your council’s Rural Water Liaison Officer before any work starts.
Can I take the water sample myself?
Not for the grant. The lab must take it, using its own sterile bottles and methods. A self-filled kit won’t be accepted.
Does the grant pay for the water test?
Yes, as part of completed works. Sampling and analysis before and after count as qualifying works, but testing on its own isn’t funded.
