SEAI grants: can a new self-build qualify?
A new self-build cannot claim these heat pump or solar grants. Check the age tests, approval rules and other supports before accepting an installer’s quote.
Stage 3: Arrange finance and budget
Self-building with savings and no lender in Ireland? What changes: insurance, certification, Help to Buy, and borrowing against the finished home afterwards.
Plenty of people building in Ireland want to avoid a self-build mortgage. They have savings, a site that came with the family, or the money from selling a previous home. Some plan to build with cash and borrow at the end, and others plan never to borrow. You must arrange the inspections, payment checks and insurance that a lender would otherwise require. Building Regulations are the legal standards for the home’s design and construction; building control is the system of notices and compliance records that still applies without a lender.
A self-build mortgage comes with payment conditions that protect the lender. Depending on its requirements and your certification route, these can include:
Without a lender, you set your own payment schedule. Planning and building-control duties still apply, including Building Regulations compliance. Arrange your own inspections and payment checks, and agree insurance and the records you will need for a future sale or loan before work starts.
Cash builders often run into the same problem: the money runs out when the shell is up. Plan phases that each leave a safe, dry result.
Price each phase with VAT before you begin, and keep a contingency for the whole job. The cost guide shows how to build up the budget, and the stages guide lists the order of work. Planning permission does not last forever, so check how long yours runs in the permission duration guide before you stretch a build over years.
With no lender checking cover, it is easy to skip, and skipping is a risk. A fire, a theft of materials or a worker’s injury with no cover can cost more than the savings you built with. Read the self-build insurance guide and if you manage the work yourself, insurance when you project manage.
How you pay does not decide the building-control route. Discuss it with your architect, engineer or building surveyor before filing the commencement notice, the notice to your council before construction starts:
An opt-out is not permission to skip professional checks. Agree inspections and written evidence of compliance with your professional and solicitor, and ask your insurer and any prospective lender what they will accept before choosing. It does not guarantee later finance. Keep records as work proceeds: inspections missed before work is covered cannot reliably be recreated afterwards.
Help to Buy for self-build is a refund of income tax and other taxes you have paid, and it is tied to a qualifying mortgage and a qualifying build. If you pay in cash with no mortgage, you should assume it is not available. If you might borrow later, read the Help to Buy guide now, and check Revenue’s claim and mortgage-drawdown timing before you budget for a refund. Grants for the energy performance of the house are separate, and the SEAI guide explains what applies to a new home.
Equity release here means borrowing against the value of the finished house, rather than a particular loan product.
Borrowing on a finished house is often easier than borrowing to build it, because the lender can see what it is lending against. Expect it to ask for:
Policies differ on how soon after completion they will lend, which certification routes and professional records they accept, and how they treat a house you built yourself. Ask two or three lenders before you start and write down their answers. The lenders comparison is a starting point for who to ask. If you need to bridge a gap during the build rather than after it, see funding a gap in the build.
A lender’s stage payments act as a brake: money goes out when an inspector confirms the work is done. With your own money you need your own brake.
The saving from skipping interest is easy to see. The other costs are not, so list them before you decide.
Neither route is better for everyone. If you plan to use cash to reach weathertight and then borrow to finish, speak to a prospective lender before starting. Ask whether it will accept a part-built house and what planning, insurance and compliance records it needs for the stages built before it joined. The mortgage guide shows what it normally asks for.
Some records are hard to replace after the builder has gone. Keep a single folder, on paper and in a cloud backup, with the planning decision and conditions, drawings showing what was built, commencement documents, professional inspection reports, the BER certificate, guarantees for the roof, windows, heating and wastewater system, and electrical and gas completion certificates where applicable. On the statutory route, retain the registered completion certificate and supporting records. For an opt-out, retain the registered declaration and the professional compliance evidence agreed with your solicitor, insurer and any prospective lender. Ask your solicitor to check the file before you offer the house for sale or apply for a loan.
It may be possible, but completion does not guarantee a loan. Lenders differ on accepting a house you built yourself and the evidence for your certification route. Expect a valuation, a solicitor's review of title and compliance documents, and questions about how it was built. Ask two or three lenders what they need before you start, so you collect it as you go.
Yes. No lender is requiring it, so nobody will remind you. A site policy covers the works, materials and your liability to people on site, and the contractor's own insurance usually covers only their work. See the self-build insurance guide for the covers.
Paying cash does not decide this. For a new single dwelling on a single-unit development, the owner can submit an opt-out declaration with the commencement notice. A valid registered opt-out removes the assigned-certifier and statutory completion-certificate requirements, but Building Regulations compliance and remaining commencement requirements still apply. Otherwise, appoint the assigned certifier before filing. Agree professional inspections and evidence with your solicitor, insurer and any prospective lender before choosing.
Help to Buy is paid against a qualifying mortgage or against the cost of a build financed that way, with conditions on the lender, your tax record and the home. Read the current rules on Revenue's site. If a mortgage is not part of the plan, treat the scheme as unavailable until Revenue says otherwise.
You avoid interest during the build, which is real money on a long project. But you may build more slowly, which can raise costs and leave a shell exposed, and you tie up savings that might be better kept as a reserve. Work out the total, not just the interest.
If the finished house has no mortgage, ask a lender about taking out a mortgage against it. If it already has a mortgage, ask about increasing or replacing that mortgage. The lender will value the house and want proof it was built to regulations. Equity release products and rates vary and change, so compare several lenders and ask about fees.
Plan the phases so each one leaves the house safe. The guide to funding a gap in the build covers the options. Stopping with a house that is not weathertight is the worst place to stop.
