Finding the Best UK Lender for a New Build Mortgage

New build mortgages have typically been a specialist product, but as more mainstream lenders start offering similar lending, the marketplace is growing.

Suppose you're keen on the convenience of buying a new build home or flat. In that case, the best option is to seek application support from an independent broker who can advise which lenders offer the most competitive terms, and where you're most likely to be approved.

For bespoke advice from a whole-of-market broker on the best new build mortgages in the UK, contact Revolution Brokers on 0330 304 3040, or email us at [email protected].

How Lending Criteria Works on New Build Mortgage Applications

The lending criteria for new build mortgages tend to be stricter than for established homes - this is primarily because it is hard to get an accurate valuation.

Mortgage providers may also ask for confirmation that the construction adheres to relevant standards required by indemnity schemes to ensure there is a ten-year warranty in place.

For a borrower, you will find fewer lenders offering new build mortgages, often higher interest rates and higher deposit requirements. So expert advice from an independent broker is essential to avoid paying over the odds.

Many new build mortgages are capped at 80% or 90% of the property value, although some lenders will offer mortgages off-plan if you're buying before the construction work has completed.

Where there are incentives to buy, such as cashback, a lender might be more cautious, mainly if purchase incentives equate to 5% or more of the property sale price.

Which Lenders Offer the Best New Build Mortgage Deals?

Each lender will have different criteria, so the only sure way to find the most competitive deals is to consult a whole-of-market broker who can recommend the best products, and the lowest rates currently available anywhere on the UK market.

New products are launched regularly, so an independent broker will have access to specialist lending options that are not available directly to the public, and maybe a much more cost-effective option.

How Does the Application Process Work for New Build Mortgages?

In many cases, banks and lenders do not offer new build mortgages directly to the public. It can also be far more cost-effective to consult a broker, who can advise which lenders are offering the best rates, and are most likely to approve your application.

Making speculative applications can rack up credit searches on your credit file, which can cause problems if you have multiple rejected mortgage applications.
