What Is New Build Boost?

New Build Boost is a home financing scheme introduced by Gen H designed to help people purchase new-build properties with a lower deposit. It combines a standard mortgage with an interest-free equity loan to lower upfront costs and improve affordability.

Key Features:

  • Buy with just a 5% deposit

  • Get a 15% interest-free equity loan from Gen H

  • Take out an 80% LTV mortgage

  • The equity loan remains interest-free for the full mortgage term

  • You own 100% of the property

For the first five years, the equity loan is locked at its original value. After that, repayments adjust with the market value of the home but are capped at twice the original loan amount.

Who Can Apply?

The scheme is open to:

  • First-time buyers and existing homeowners

  • Buyers purchasing a new-build home from Persimmon or Charles Church

  • Those with a deposit of 5–15% (from savings or a gift)

📍 Not available in Scotland or Wales

How Does It Compare to Help to Buy?

While inspired by the Help to Buy model, New Build Boost introduces several differences:

Feature Help to Buy New Build Boost
Buyer eligibility First-time buyers only Includes homeowners
Interest-free period 5 years Entire mortgage term
Loan-to-value 75% mortgage + 20% loan + 5% deposit 80% mortgage + 15% loan + 5% deposit
Equity loan value adjustment Based on market value from year 6 Fixed for 5 years, then adjusts (capped)
Application process Separate mortgage and loan steps Integrated application through Gen H

In short, New Build Boost offers greater long-term predictability and simpler access, even for those who’ve owned before.

Why It Matters

With the end of Help to Buy, many buyers were left without viable support. Gen H’s New Build Boost could provide a lifeline for those struggling with deposits or affordability—especially in today’s challenging housing market.


Is It the Right Choice for You?

While schemes like this can open doors to homeownership, they aren’t for everyone. Monthly repayments may be higher than a standard mortgage, and if your new build is leasehold, you’ll need to budget for service charges or ground rent.

✅ Speak to a mortgage broker or financial advisor to evaluate whether this fits your budget and long-term goals.

Key takeaways

  • Bigger Borrowing Power: Gen H is offering the potential to borrow more, with borrowers being assessed against 80% Loan to Value (LTV) criteria. For some eligible borrowers, they might be able to borrow up to 5.5 times their income. And what’s better, buyers will own the entire home from day one.
  • Potentially Smaller Deposits: New Build Boost unlocks 80% LTV mortgages on new-build homes with just a 5% deposit. It aims to help first-time buyers, and those looking to buy a new build, get on the ladder with less savings required.
  • Thinking Outside the Box: Gen H aren’t your typical mortgage lender, and this new product seems to reflect that. They’re talking about how they can be more flexible and “reimagine the new build buying journey.”
