If your home insurance policy still lists a rebuild figure from three or four years ago, you are probably underinsured — and a claim could be cut proportionally under the "average clause". Irish construction tender prices have climbed roughly 25–35% since 2021, so a rebuild quoted at €280,000 in 2021 typically needs €350,000–€380,000 today. Update your sum insured now.
What the latest reporting actually says
The Ritz Herald recently flagged a growing gap between the rebuild figures on Irish home insurance policies and the real cost of putting a damaged house back together. The reporting echoes warnings from Insurance Ireland, the Society of Chartered Surveyors Ireland (SCSI) and several brokers: a wave of underinsurance is building, and most homeowners will only discover it after a fire, storm or burst-pipe claim.
The driver is simple. Material costs — timber, insulation, concrete, copper, roof slates, uPVC fascia and guttering — rose sharply through 2022 and 2023 and have not retreated. Labour rates for qualified Irish trades have followed. The CSO's Wholesale Price Index for building and construction materials is still well above its pre-pandemic baseline, and the SCSI's House Rebuild Calculator has been revised upward in every annual update since 2021.
The result is a quiet mismatch. Policies renew automatically, sums insured drift up by a token 3–5% inflation uplift, and the real rebuild cost climbs faster than the policy can track.
Rebuild cost is not market value (and this trips people up)
Most homeowners conflate two very different numbers. Market value is what a buyer would pay for your house and the site it sits on. Rebuild cost is what a builder would charge to reconstruct the structure from foundations up, including demolition, site clearance, professional fees, VAT and compliance with current Building Regulations.
In parts of Dublin, market value can sit well above rebuild cost. In rural Leitrim, Roscommon or west Cork, the opposite is often true — rebuild cost can exceed market value, especially for older stone or dormer properties. Your insurer wants the rebuild figure, not the Daft.ie asking price.
The SCSI's 2024 guide put average rebuild costs (excluding site value) at indicative levels such as:
- Dublin 3-bed semi: €2,650–€2,900 per m²
- Cork / Galway / Limerick 3-bed semi: €2,400–€2,650 per m²
- Rural one-off bungalow: €2,100–€2,400 per m²
These are indicative ranges for guidance only — confirm exact figures with a chartered surveyor or your broker before adjusting cover.
The "average clause" — the part nobody reads
Almost every Irish household policy contains an averaging condition. If you are insured for 70% of the true rebuild cost and you suffer €40,000 of fire damage, the insurer can pay 70% of that loss — €28,000 — and leave you to find the rest. Averaging applies even to small partial claims, not just total losses.
Worked example: a Limerick semi with a true rebuild cost of €360,000 is insured for €260,000 (72%). A kitchen fire causes €55,000 of damage. The settlement, after averaging, falls to roughly €39,700 — a €15,300 shortfall before the excess is even applied.
This is the new risk the headlines are warning about. It is not that premiums are rising (they are, modestly). It is that the sum insured itself has fallen behind reality.
A 20-minute self-audit for Irish homeowners
You do not need to commission a full survey to sanity-check your cover. Work through these steps before your next renewal:
- Measure the gross external floor area of your home in square metres, including the garage if attached.
- Multiply by an indicative SCSI rate for your region (see ranges above).
- Add 10–15% for professional fees, demolition and VAT if your policy schedule shows these are not already included.
- Add the cost of outbuildings, boundary walls, paved driveways, solar PV and oil tanks — these are part of "buildings" cover but routinely forgotten.
- Compare the total to the sum insured on your current schedule. If you are within 90%, you are broadly fine. Below that, contact your broker.
- Photograph each elevation and the roof from ground level, and store the images with the policy documents.
If your home is a protected structure, thatched, has natural slate, lead valleys or cast-iron rainwater goods, the per-square-metre rate climbs considerably and a chartered surveyor's rebuild assessment is worth the €350–€600 fee.
Where roof and rainwater systems quietly inflate the figure
A surprising proportion of post-storm claims in Ireland involve the roof envelope: slipped or broken slates, lifted ridge tiles, torn felt, damaged fascia and soffit boards, and dislodged or fractured gutters. Replacement costs for these elements have moved disproportionately fast.
Indicative current Irish-market ranges (confirm with your contractor):
- Full uPVC fascia, soffit and guttering replacement on a 3-bed semi: €2,800–€4,500
- Natural slate roof recover, 3-bed semi: €14,000–€22,000
- Concrete tile re-roof, 3-bed semi: €9,500–€14,000
- Storm-damaged ridge and verge repairs: €450–€1,200
If your policy still assumes 2020 rates for these items, even a partial roof claim can bump into the averaging clause. Keeping the rainwater system maintained also matters from an insurer's perspective: water ingress claims linked to blocked gutters are often disputed as "gradual damage" rather than sudden, accidental loss. A documented annual gutter cleaning and inspection record strengthens your position if it ever comes to a claim.
Storm Éowyn, Storm Bert and the claims pattern
The January 2025 windstorms caused tens of thousands of household claims across Munster and the south-east, with average payouts for roof and guttering damage running notably higher than equivalent claims five years earlier. Three patterns emerged from broker debriefs:
- Underinsurance averaging applied in roughly one in five buildings claims, particularly on properties extended since 2018 where the sum insured had never been revised to reflect the new floor area.
- Fascia, soffit and gutter damage was frequently capped because policies treated these as "external decoration" with sub-limits of €2,000–€3,000.
- Delayed repairs led to secondary damp claims being declined, because insurers argued the homeowner had failed to mitigate.
The practical lesson: get a post-storm inspection done quickly, document everything, and do not assume the headline sum insured is the ceiling — sub-limits inside the policy can bite first. Our notes on roof repairs across Cork, Limerick and Munster walk through what a thorough inspection should cover.
Extensions, attic conversions and solar PV — the silent underinsurance trigger
If you have done any of the following since your last policy review, your sum insured almost certainly needs revising upward:
- Rear or side extension (every additional m² should be added at full rebuild rate)
- Attic conversion with dormer or Velux
- Garage conversion to habitable room
- New kitchen above €15,000
- Solar PV array (typically €8,000–€14,000 installed)
- Heat pump installation (€10,000–€16,000 typical, often grant-aided)
- External wall insulation (adds rebuild complexity and cost)
SEAI-grant-funded works in particular are frequently omitted because homeowners view them as energy upgrades rather than buildings improvements. Insurers view them as part of the structure you would need to reinstate.
What to ask your broker at renewal
Skip the price-only conversation and put these five questions in writing:
- What rebuild cost per square metre is my current sum insured based on, and what year was it set?
- Does my policy include an "index-linked" or "day-one" uplift, and what percentage?
- Is there a "no average" or "underinsurance waiver" clause available on this policy?
- What are the sub-limits for external items — fascia, soffit, guttering, boundary walls, gates, paving?
- Are accidental damage and escape-of-water cover both included as standard?
A broker who cannot answer these clearly is a reason to shop elsewhere. The Competition and Consumer Protection Commission and the Central Bank's Consumer Protection Code both require clear disclosure of these terms.
Practical maintenance that protects the policy
Insurers increasingly look at maintenance evidence when assessing claims. Keep a simple folder — paper or digital — with:
- Annual gutter clean receipts and before/after photos
- Roof inspection reports (every 3–5 years for slate, 5–7 years for concrete tile)
- Records of any fascia, soffit or fascia and soffit replacement work
- Boiler and electrical certs
- Chimney sweep records if you have a solid-fuel stove
For homeowners in older Limerick city housing stock, where cast-iron downpipes and original timber fascia are still common, documented upkeep is particularly important — see our notes on Limerick gutter repairs and replacements for what good practice looks like on these properties.
Frequently Asked Questions
How often should I review my home insurance rebuild cost in Ireland?
At every renewal, and immediately after any extension, attic conversion or major refurbishment. As a minimum, run the SCSI House Rebuild Calculator once a year. A formal chartered surveyor's reinstatement valuation is worth commissioning every 5–7 years, or sooner for protected structures and one-off rural homes.
Will my insurer automatically increase my sum insured with inflation?
Most policies apply an index-linked uplift, typically tied to the Wholesale Price Index for building materials, but this generally lags real construction tender inflation by 12–18 months. During periods of rapid cost rises — like 2022–2024 — the index-linked figure can drift well below true rebuild cost, leaving you exposed to averaging.
What is the average clause and how does it affect a claim?
The average clause allows an insurer to reduce a claim payment in proportion to the level of underinsurance. If you are insured for 75% of the true rebuild cost, the insurer can pay 75% of any claim — even a small partial loss. It applies to buildings and contents sections separately.
Are storm-damaged gutters and fascia covered by standard home insurance?
Usually yes, under buildings cover, but sub-limits and exclusions are common. Many Irish policies cap external rainwater goods at €2,000–€3,000, exclude "wear and tear", and require evidence of recent maintenance. Keep dated photos and service records to support any storm claim.
Should I get a surveyor or trust an online rebuild calculator?
For a standard estate-built 3 or 4-bed semi-detached home, the SCSI online calculator is generally accurate enough. For one-off houses, extended properties, period homes, thatched cottages or anything with non-standard materials, commission a chartered surveyor — the €350–€600 fee is trivial compared to a refused claim.
Does claiming for gutter or roof damage push up my premium significantly?
A single weather-related claim typically affects renewal premiums modestly — usually 10–20% — and most insurers retain you as a customer. Multiple claims within three years, or evidence of poor maintenance, have a much larger impact. Preventive maintenance almost always costs less than the long-term premium effect of an avoidable claim.
