Halifax mortgages: the lender rules that are actually useful in 2026

Halifax is most useful when you focus on a few concrete rules that genuinely change decisions: 95% lending rules, a soft-search Agreement in Principle, a clear annual overpayment allowance, and a self-employed criteria section that explicitly includes some one-full-year cases.

That makes the Halifax route more useful when it stays focused on criteria and fit instead of cashback-style filler.

Start here

Start with Halifax early if:

• you are a first-time buyer or home mover testing a 5% deposit route
• you want an Agreement in Principle that only uses a soft credit check
• you are self-employed and need a lender with a published one-full-year consideration example rather than a generic ‘most lenders need two years’ answer
• you already have or expect to have early repayment charges and want a lender page that states the overpayment allowance clearly

Halifax is a weaker fit to start with if:

• you want a 95% mortgage to work with Shared Ownership, shared equity or Right to Buy, because Halifax excludes those routes from this product
• you want a 95% interest-only route, because Halifax does not allow interest-only borrowing here
• you specifically want an offset mortgage, because Halifax does not currently offer one

Deposit and AIP rules

Halifax’s 95% mortgage page is much clearer than many comparison articles.

Key points include:

• a 95% mortgage can allow eligible first-time buyers and home movers to borrow up to 95% of the property value
• a minimum 5% deposit makes up the remaining amount
• Halifax offers eligible customers 90% to 95% LTV mortgages depending on circumstances and deposit amount

The same 95% page also makes the exclusion list explicit. This route is not compatible with:

• interest-only mortgages
• publicly assisted loans such as shared equity schemes
• shared ownership and Right to Buy
• remortgaging to Halifax from a different provider with a 95% mortgage

That is exactly the kind of detail old lender review pages usually blur.

Halifax also sets out a clear Agreement in Principle process:

• the AIP is obligation-free
• it only involves a soft credit check
• it does not affect your credit score
• it is not a guarantee, because the full application later involves more detail and a full credit check

For a user choosing between lenders, that is much more decision-relevant than a generic ‘good first-time buyer lender’ label.

Self-employed criteria

Halifax’s intermediary criteria is one of the main reasons to look closely at the lender for self-employed cases.

Published Halifax criteria point	What it means
Self-employed income details must be entered for the latest 2 years of trading	Halifax wants full trading-year evidence where available, not loose recent-month figures
Figures should only be entered for each full year of trading	Partial-year optimism is not the same as a usable affordability input
Where the customer has been trading for less than 2 years but for at least one full year the application can be considered	One-full-year cases are possible, but they should be treated as narrower manual routes
Accounts are then the preferred method of income verification	A one-year self-employed case needs cleaner documentation, not weaker documentation
The income level used is the lower of the latest year or the average of the last 2 years	A stronger latest year does not automatically become the working affordability number
Full accounts must be finalised and the year end must not be more than 18 months before application	Drafts, loose management figures and stale year-ends weaken the case quickly

This is the practical reading:

• Halifax can be a serious lender to check for self-employed borrowers, including some one-full-year cases
• Halifax is still not a shortcut around evidence quality
• Halifax should not be sold as though it simply ‘likes self-employed applicants’ without the lower-of calculation and document limits being made explicit

If you want to test this against your own structure before a broker call, use the Self-Employed Diagnostic and the Self-Employed Mortgage Guide.

Overpayments and product fit

Halifax’s overpayment page sets out a limit of 10% of the amount owed as of 01 January in that calendar year where early repayment charges apply. If you go above the allowance, the fee applies only to the amount above that threshold.

That is useful because it gives borrowers a concrete starting point for three questions:

1. Are you likely to overpay materially during the fixed period?
2. Does the 10% annual allowance cover what you actually want to do?
3. Would waiting until an ERC reduces or ends change the decision?

There is also a useful negative fit point here that many lender roundups get wrong.

Halifax has a help page explaining what an offset mortgage is, but that same page also makes clear that Halifax does not currently offer offset mortgages. Anyone specifically shopping for offset should therefore treat Halifax as an educational source on the concept, not as a current shortlist entry.

Next steps

• Use the Mortgage Comparison Calculator if the real question is Halifax versus the wider market
• Use the First-Time Buyer Advice Page if your main issue is 5% deposit planning rather than lender choice alone
• Use the Self-Employed Diagnostic if your case depends on one-full-year or two-year self-employed evidence
• Use the Remortgage Calculator and Mortgage Deal Ending Guide if the overpayment and switch timing questions matter more than purchase eligibility
