Conservatory Installation Costs in Ireland: 2026 Price Guide
Adding a conservatory is one of the most popular ways to expand and enhance Irish homes, offering extra light, living space, and a seamless bridge to the outdoors. Whether you’re after a classic suntrap for relaxing or a fully insulated extension to use year-round, conservatory prices in Ireland vary widely based on specifications and finish.
In 2026, homeowners should budget between €12,000 and €22,000 for a standard 12 square metre conservatory, covering supply and installation. For those seeking a higher-spec, insulated sunroom of around 15 square metres, expect to pay circa €18,000 to €35,000. Premium orangeries, which offer the highest build quality and insulation, generally range from €30,000 to €55,000. Dublin prices are typically 15–20% higher than elsewhere, reflecting greater demand and increased labour costs.
Factors like size, materials, glazing type, foundation requirements, and bespoke features all play an important role in the final bill. This guide will break down the costs, discuss what affects pricing, highlight available grants, and offer practical tips to ensure your conservatory project is a happy investment.

What Influences the Cost of a Conservatory?
The overall spend on your conservatory depends on a combination of choices and site conditions. Understanding these factors will help set your expectations and priorities.
- Size & Complexity: Larger builds and intricate shapes increase both materials and labour costs.
- Frame Material: uPVC is usually cheapest, aluminium comes mid-range, and hardwood frames command a premium.
- Roof Type: Polycarbonate roofs are the most affordable, while glass and insulated warm roofs deliver more comfort at a higher price.
- Glazing: Double or triple glazing boosts thermal performance but adds to the upfront cost.
- Foundations: Poor soil, uneven sites or access issues can add €3,000–€6,000 for foundations and site prep.
- Finishes & Features: Extras like underfloor heating, bespoke lighting, and custom paints drive up the final price.
Regional Price Differences – Dublin vs the Rest of Ireland
Dublin homeowners should expect to pay a premium. Labour charges and demand in the capital typically push conservatory costs 15%–20% above the national average. That means a standard conservatory in Dublin may start nearer €14,000–€26,000, and premium builds run even higher.
Elsewhere in Ireland, prices tend to be steadier, but rural locations with challenging access or ground conditions can also see costs rise due to logistics or groundwork requirements.
Planning Permission: What You Need to Know
For most homeowners, installing a conservatory up to 40 square metres at the back of the house usually doesn’t require planning permission—provided the new room stays within certain boundaries for height, distance from boundaries, and overall site coverage. It’s vital, however, to double-check with your local authority or seek professional advice, as local rules or unusual site situations can alter requirements.
Financial Supports & SEAI Grants in 2026
While there’s no direct grant for conservatory installation, the Sustainable Energy Authority of Ireland (SEAI) now offers a Windows and Doors Grant (since March 2026), as well as longstanding insulation grants. These can significantly offset the cost if you choose upgraded energy-efficient glazing or insulation as part of your project.
For best value, consider integrating high-performance windows, doors and insulation—then check SEAI’s site or speak to your installer about available grants and how to apply.
Practical Tips for a Hassle-Free Conservatory Build
- Get at least three written quotes from reputable, registered installers.
- Ask to see examples of previous work and confirm industry credentials.
- Clarify what’s included in your quote (design, construction, electrics, finishes, VAT).
- Opt for quality glazing and insulation if you plan to use the space year-round.
- Have a written contract detailing costs, timelines, and materials before paying a deposit.
- Check with Revenue on VAT rates—some energy-efficient upgrades may attract reduced VAT.
