A modular home mortgage in Ireland is possible in some cases, but it is not as simple as asking a bank to fund any factory-built unit. The lender is not just looking at a house shape. It is checking title, planning, valuation, certification, security, insurance and whether the completed property can be sold if the loan ever has to be enforced.

This guide explains the mortgage route without promising approval. Use it before you compare suppliers, because the funding route can decide which modular systems, warranties and paperwork are acceptable.
Quick answer
For an Irish modular home to be mortgage-ready, the file usually needs more than a brochure and a price. Expect questions around:
- planning permission or a clear exemption route
- land ownership and title
- valuation and resale evidence
- building system certification
- warranty and completion sign-off
- stage payments and drawdown timing
- insurance
- BER or energy performance
- site services and access
A lender may support a specific modular-home route or supplier arrangement, but that does not make all modular homes mortgageable. Treat every lender, product and site as separate.
The PTSB and BuildWright example
PTSB announced on December 31, 2025 that it was partnering with Irish modular building company BuildWright to provide mortgages for new modular homes. The notice says the homes are A2-rated, built offsite at fixed price, and that customers can avail of PTSB Green Mortgage fixed lending rates. It also says the PTSB modular home mortgage is currently only available to customers purchasing their modular home via BuildWright.

That distinction matters. If you are comparing suppliers, do not read one lender/supplier partnership as a market-wide mortgage guarantee. Ask each supplier:
- Which lenders have actually funded this exact system?
- Is the home mortgageable before, during or only after completion?
- What certification and warranty are included?
- Who provides stage-completion sign-off?
- What happens if the lender's valuer disagrees with the expected value?
Why lenders are careful
A mortgage is secured against property. That means the lender has to be comfortable that the finished home is durable, compliant and marketable.
Modular construction can be high quality, but the word "modular" covers very different products:
| Product type | Finance implication |
|---|---|
| Garden room or small studio | Usually not a standard mortgage product |
| Cash-funded auxiliary-style unit | May need planning, services and insurance checks; mortgage route depends on structure and lender |
| Full residential modular home | More likely to need certification, warranty, building control and lender-specific approval |
| Supplier-linked lender route | Can be clearer, but only inside that named lender/supplier arrangement |
This is why a lower quote is not always the better finance route. A cheap unit may be fine for cash buyers but difficult for mortgage security.
Planning comes before finance
Citizens Information explains that planning permission is the process where your local authority agrees to proposed building work. It also notes planned 2026 changes, including possible small detached homes in back gardens, but says those changes have not started yet and draft regulations still need approval.
For modular homes, planning affects finance because a lender will not want ambiguity around the legal use of the property. The Government's April 21, 2026 announcement on auxiliary habitable dwellings is important, but the detailed conditions and timing still matter.
If your project is in the small-garden-home category, read modular homes planning permission Ireland and the 45sqm planning exemption guide before talking to a broker.
Finance routes compared
Cash
Cash gives the most flexibility, but it does not remove planning, building control, insurance or services. It also puts all site risk on you. Ask for a full installed cost rather than the unit price only.
Personal loan or credit union loan
This may work for smaller garden rooms, studios or fit-out elements. The limitation is loan size, repayment term and rate. It may not suit a full residential home.
Mortgage or mortgage top-up
This is the route most buyers ask about for a full modular home. It is also the most paperwork-heavy. Expect lender questions on title, planning, valuation, construction method, warranty, drawdown and completion.
SEAI/SBCI energy-upgrade loan
The SEAI Home Energy Upgrade Loan Scheme is not a general modular-home mortgage. SEAI says it is for eligible energy upgrade works and has rules around grants, One Stop Shops or Community Coordinators, and minimum BER uplift. It may be relevant to certain energy works, but it should not be treated as automatic funding for a new modular home.
What a broker or lender may ask for
Prepare a folder with:
- Site address and map.
- Evidence of land ownership or right to build.
- Planning permission, exemption evidence or planning-adviser note.
- Supplier quote showing unit, foundations, services, transport, VAT and exclusions.
- Construction specification.
- Certification or approval documents for the building system.
- Warranty information.
- Project timeline and stage-payment schedule.
- Insurance position during transport and build.
- BER or energy-rating route.
- Final connection and completion sign-off plan.
If you cannot answer those questions, the mortgage conversation is premature.
Price and mortgageability are linked
Our modular homes prices Ireland guide separates unit price from finished site price. That separation matters even more when finance is involved. A lender wants to know what is being funded, when it becomes fixed to the land, and what evidence supports the final value.
Use a three-column budget:
| Cost line | Cash quote | Mortgage-ready quote |
|---|---|---|
| Unit supply | Supplier price | Supplier price |
| Foundations and services | Often site-specific | Must be documented clearly |
| Certification/warranty | May vary | Usually more important |
| Professional fees | Planning, engineer, BER as needed | More likely to be required |
| Contingency | Essential | Essential |
The mortgage-ready route may look dearer upfront because it includes paperwork and sign-off that a cash quote leaves out.
Supplier questions before applying
Ask every supplier:
- Have Irish lenders funded this specific model before?
- Which lender or broker was involved?
- Is the system accepted by a warranty provider?
- Is the home treated as a permanent structure?
- What documents does the valuer receive?
- Are stage payments needed before mortgage drawdown?
- What happens if planning changes are delayed?
- Is the quote fixed, and for how long?
Do not accept "mortgage approved" as a generic claim. Ask who approved what, for which site, and under what conditions.
Bottom line
A modular home mortgage in Ireland is a paperwork and risk question before it is a product question. PTSB's BuildWright notice shows that lender-backed routes exist, but it also shows how specific they can be.
Start with land, planning, system evidence and valuation. Then compare finance. If the modular unit, site and lender file do not line up, the project may still be possible with another route, but it should not be sold as a standard mortgage-ready home.
