Can you get a 100 percent mortgage with bad credit?
A 100 percent mortgage is a loan covering the full purchase price of a property, requiring no deposit from the buyer. In the UK market of recent years these products are rare even for borrowers with spotless files, and for borrowers with adverse credit the honest answer is that they are effectively unavailable. We have found no segment of the regulated market offering zero-deposit lending to applicants with meaningful credit problems, and any firm advertising exactly that combination should be treated as a scam risk.
This page exists because the search is common and the marketing around it is often misleading. Rather than tease an option that does not exist, we explain why lenders refuse to stack these two risks, what the small number of genuine zero-deposit products actually require, how family-assisted alternatives work, and the realistic routes from no deposit and bad credit to a completed purchase. We are an information website, not a broker or lender, and nothing here is advice.
Why will no lender combine zero deposit with adverse credit?
Lending at 100 percent loan to value means the lender has no equity cushion at all. If prices fall even slightly, the loan immediately exceeds the property value and the borrower is in negative equity. The lender can only absorb that exposure for borrowers whose repayment record suggests arrears are very unlikely, because repossessing a property in negative equity crystallises a loss.
Adverse credit is, by definition, evidence that repayment has failed before. Combining the two would stack the highest probability of default onto the lowest protection against loss, which fails any credit committee and sits awkwardly with regulatory responsible lending obligations. This is also why deposit requirements rise with the severity of credit problems across the entire adverse market: the deposit is the mechanism that makes adverse-credit lending viable at all.
It is worth being equally honest about the past: 100 percent and higher lending did exist before 2008, including for credit-impaired borrowers, and it ended in repossessions and negative equity at scale. The current market structure is a lesson learned, not an oversight waiting for a clever workaround.
What 100 percent products do exist, and who qualifies?
A small number of genuine zero-deposit products have appeared in recent years, most prominently rent-track-record lending, where a history of paying rent reliably substitutes for a deposit as evidence of capacity. These products are aimed at trapped renters who can clearly afford payments but cannot save while renting.
Their credit requirements are the point to absorb: applicants generally need a clean recent credit record, with no recent defaults, CCJs or missed payments, alongside a sustained record of on-time rent. The products demand stronger conduct evidence than ordinary lending precisely because there is no deposit, which is the opposite of an adverse-credit product. If your file carries recent credit events, these products are not a route around the deposit; they are a reason to repair the file first.
Can a guarantor or family member bridge the gap?
Family-assisted products are the closest legitimate relatives of the 100 percent mortgage, because they replace the buyer deposit with family resources. They do not generally remove the credit requirements, but for buyers whose problem is deposit rather than severe credit history, or whose credit issues are minor and ageing, they can be genuinely useful. The main structures are below; availability with adverse credit varies by lender and severity, and a broker can confirm what fits a specific file.
| Product type | How it works | Bad credit reality check |
|---|---|---|
| Family savings as security | A relative locks savings, often 10%, with the lender for a set period | Some providers tolerate minor historic issues; recent adverse usually declines |
| Charge over family property | Lender takes a legal charge over equity in a family home | Family home is at risk; credit criteria still apply to the buyer |
| Guarantor mortgage | A relative guarantees the repayments contractually | Now rare; guarantor liability is serious and credit checks still run |
| Joint borrower sole proprietor | A relative joins the mortgage but not the deeds to boost affordability | Helps affordability, not credit history; both files are checked |
| Gifted deposit | Family gives the deposit outright with a signed gift letter | Most flexible route; turns the case into a normal adverse-credit application |
What are your realistic paths to buying?
With no deposit and adverse credit, the workable strategies all involve converting time into either deposit, credit repair, or both. None is glamorous; all are real.
- A gifted family deposit of 10 to 15 percent plus a specialist lender is the fastest legitimate route, because it changes the case into a standard adverse-credit application.
- Saving 5 to 10 percent while your credit events age does double duty, since each anniversary of a default or CCJ opens cheaper criteria tiers.
- A Lifetime ISA adds a 25 percent government bonus to first-home savings within its limits and conditions, accelerating the deposit timeline.
- Shared ownership lowers the cash needed by mortgaging only a share of the home, and some participating lenders accept lighter adverse credit.
- Right to Buy, for eligible council tenants in England, can supply the deposit through the discount, and some specialists lend the full discounted price.
- Credit repair first, purchase second: twelve months of clean conduct, satisfied defaults and electoral roll registration can move you from unlendable to lendable.
How should you judge anyone offering you 100 percent with bad credit?
With extreme suspicion. The regulated market does not offer this combination, so an offer of it is either an unregulated arrangement you should not touch, a misunderstanding of your file, or loan fee fraud, where an upfront payment is collected for a mortgage that never materialises. Check any firm on the FCA register before sharing documents or paying anything, and treat guaranteed approval language as disqualifying in itself.
The constructive next step is cheaper than a scam and more effective: read your own credit reports, talk to an FCA-regulated whole-of-market broker about where your file actually sits, and get a realistic two-path plan, that is, what is possible now with family help, and what becomes possible in twelve months without it. Buyers who take the honest route usually end up owning; buyers chasing the mythical product usually end up poorer and no closer.
Common questions
Is a 100 percent mortgage with bad credit ever approved?
In the regulated UK market, effectively never. The rare zero-deposit products that exist require clean recent credit records, and every adverse-credit lender requires a deposit, typically 10 to 25 percent depending on severity. An offer combining no deposit with bad credit acceptance is a strong scam indicator.
What is the lowest credit score that can be approved for a mortgage?
There is no universal minimum, because lenders score internally rather than using the consumer numbers from credit agencies. Specialist lenders assess the events on your file, their age and their value. The same headline score can be lendable or unlendable depending on what produced it.
How hard is it to get a 100 percent mortgage even with good credit?
Hard. Only a handful of products exist, mainly rent-track-record lending for established renters, and they demand spotless recent conduct, sustained on-time rent and full affordability evidence. Most buyers, including clean-credit buyers, still purchase with at least a 5 percent deposit.
How much can I borrow with poor credit?
Loan sizes are driven by the same income multiples as mainstream lending, commonly around four and a half times income, but adverse pricing raises the tested payment and some lenders trim multiples on adverse tiers. Deposit matters more than loan size: with poor credit, the deposit percentage decides which lenders will consider you at all.
Can my parents help me buy if I have bad credit and no deposit?
Yes, most usefully through a gifted deposit, which converts your case into a standard adverse-credit application that specialist lenders can consider. Family savings or property charge products may also work where credit issues are minor. Joint borrower sole proprietor arrangements help affordability but do not offset your credit history.
