Quick answer
- A mortgage top-up with FHS should be checked before you rely on it.
- Purpose matters: not every extra-borrowing reason is treated the same.
- Using a top-up to redeem FHS can make sense, but the valuation-based redemption amount must be understood first.

What a mortgage top-up means with FHS
A mortgage top-up is extra borrowing secured on your home after the original mortgage has been drawn down. With the First Home Scheme, a top-up is not just a normal lender decision. FHS has an interest in the property, so the purpose of the borrowing and your remaining equity position can matter.
This is especially important if you want to borrow for home improvements, education, medical costs, or to buy back part or all of the FHS equity share.
Top-up purpose guide
| Top-up purpose | Why it may be considered | Extra checks |
|---|---|---|
| Home improvements | Can improve or maintain the home that FHS supported. | Check lender approval, cost evidence and FHS no-objection requirements. |
| Medical needs | May be allowed where the borrowing purpose is clearly documented. | Keep documents and do not rely on a verbal assumption. |
| Education needs | Can be an acceptable purpose in specific circumstances. | Confirm before applying for the top-up. |
| Redeeming FHS equity | Can help buy back part or all of the FHS share. | Usually needs valuation and no-objection steps. |
| General spending | May not fit the scheme purpose rules. | Higher risk of objection. |
The 10% equity idea in plain English
One important check is whether you keep enough equity in your home after the top-up. In simple terms, the scheme does not want the homeowner\’s remaining interest to be squeezed too far by extra borrowing while FHS still has a share.
Example: if the estimated open market value is €420,000, 10% equity is €42,000. Before taking extra borrowing, the homeowner should check whether the proposed mortgage, FHS share and other security position still leave enough homeowner equity after the top-up.
Process before applying for a top-up
- Write down the purpose. Be specific: home improvement, medical, education, or redemption.
- Ask the lender if the top-up is available. Your income and mortgage affordability still matter.
- Notify FHS before relying on the top-up. FHS may need to confirm it does not object.
- Check valuation needs. If the top-up is for redemption, a valuation may be needed to calculate the FHS share.
- Do the full affordability check. A bigger mortgage can reduce cash pressure today but increase long-term repayments.
Common mistakes
- Assuming any top-up purpose will be acceptable.
- Starting home improvement work before finance and FHS no-objection steps are clear.
- Using a top-up to redeem FHS without understanding the valuation-based redemption amount.
- Ignoring the effect of higher mortgage repayments.
- Forgetting that a mortgage switch plus extra borrowing can create both switching and top-up questions.
Frequently asked questions
Can I get a mortgage top-up after using FHS?
Possibly, but you should notify FHS and get the lender and scheme position clear before relying on the extra borrowing.
What purposes are usually safer for a top-up?
Home improvements, medical needs, education needs and buying back the FHS share are the main purposes to check first.
Can FHS object to a top-up?
Yes. FHS may object if the purpose does not fit the scheme rules or if the homeowner's remaining equity position is too low after the top-up.
Can I use a top-up to buy back the FHS share?
Yes, that can be a reason for a top-up, but valuation and no-objection steps normally matter.
Do I need a valuation for a top-up?
A valuation may be needed, especially where the top-up is connected to redeeming the FHS equity share.
Is a top-up the same as switching mortgage?
No. But a switch can include extra borrowing, so both sets of rules may need to be checked together.
