Why you’re stuck
Heliodor Mortgages (Topaz Finance) is part of the closed‑book market. Closed‑book servicers typically don’t offer new products or further advances. Instead of a product transfer, the practical route is to switch to an active lender.
Your switch options
- MAA (Modified Affordability Assessment): like‑for‑like balance; based on payment history; new deal must be cheaper.
- RIO (55+): later‑life interest‑only; affordability and LTV still apply.

Quick eligibility check
- Up‑to‑date on payments (last 12–24 months)
- No extra borrowing under MAA (like‑for‑like)
- Not moving home
- Lower LTVs help (e.g., ≤ 60%)
- Ages 55+ may fit RIO route

What we’ll need
- Latest mortgage statement + 12m payment history
- 3–6m bank statements
- Pension/income evidence
- Photo ID + proof of address
Useful specifics
- Heliodor is an inactive/closed‑book administrator; no new products are typically available.
- We help you compare multiple active-lender options and select a cheaper product.
- We’re independent and not affiliated with Heliodor/Topaz.
