Quick Summary
We’ve helped plenty of people looking to mortgage steel-framed property, and whilst there are several options, it’s still a consideration for buyers because most lenders consider them as non-standard construction.
From over 100 lenders across the market, approx. 48 lenders can consider it, but each has varying policy. It often depends on the cladding material and year of build – if built in the 1970s or before there’s more risk given the approach and material at the time, and these can require a more specialist lender as a result. Modern steel constructions, particularly modular homes / property built with Structural Insulated Panels (SIPs), are usually more widely accepted.
This is why speaking to an advisor beforehand is important – they can get the details of the property and ensure they match you with the lenders’ policy before applying, and with some lenders, can even get a pre-valuation assessment to indicate acceptance before you spend any money on applications and physical surveys.
In this article:
Yes, it’s possible, but your ability to get a mortgage will depend on the type of steel-framed house you’re interested in. Some lenders won’t approve mortgage applications from people buying these properties because of resale and insurance concerns.
Other lenders will only say ‘yes’ to certain types of steel-framed construction. Thankfully, some flexible lenders provide steel-framed property mortgages in most cases – both standard house builds and bungalows – and the right mortgage broker can help you find them.
Steel-framed houses are often considered risky, making many lenders more cautious than usual. Nowadays, most construction companies use wooden frames rather than steel.
However, many steel-framed houses were built after World War II to house people displaced by the war. These houses weren’t designed to last a long time, and because of this, some lenders are reluctant to offer mortgages for them.
Potential problems can include structural issues, poor insulation, and high energy costs, though not all steel-framed properties have these issues.
A steel-framed building can last for decades, as long as it’s properly cared for. If you pay a surveyor to do a thorough inspection, they can determine the quality of the home and help you avoid making a bad investment.
Potentially, but selling a steel-framed home can be difficult. Buyers may be reluctant to buy the property from you because of the challenges they face getting a mortgage.

Lending criteria for steel-framed properties
Lending criteria can vary significantly from one lender to the next, as each property can be a unique case, and something that is difficult to have a black and white policy about. For this reason most lenders will insist that a structural engineer or building surveyor carry out a thorough survey, and will lend based on what the valuer tells them about how “suitable” it is.
To assess suitability, they look for current condition, construction material risks, and any impact to resale prospects. The age of the property will often be considered. Some lenders will only accept properties that were built after the 1950s. Others are even more selective, insisting the property must have been built after 2000.
Once this is understood, lenders can decline to lend or in some instances, limit the amount they’ll lend to a certain loan-to-value (LTV) – For example, 75% – to limit the risk exposure should something go wrong. That said, there are lenders that if happy with the property will offer standard terms, and access to their full range of products up to the highest LTVs.
Which lenders will consider these properties?
Here are a few examples of the restrictions you might encounter from specific lenders:
The Mortgage Lender
They will only approve mortgages for those buying a modern, purpose-built flat. They will also only lend to those who can provide a 3-year address history and are likely to take student loans into account when assessing applicants’ affordability.
Norton Home Loans
Requires a full valuation before deciding whether to approve an application. If the surveyor says the property isn’t fit for conventional mortgage lending, the LTV will be restricted to a maximum of 50%.
Coventry Building Society
Will only consider properties that have been built on or after 1st January 1990. They also insist that at least 67% of the property’s cladding must be brick or stone. Properties with large concrete panels, timber, plastic metal sheeting and tiles are excluded in many, but not all, cases.
Halifax
They will base their decision on the valuer’s report and accompanying comments. All non-standard construction properties are assessed on individual merit.
These examples show that getting a mortgage on a steel-framed home can be complicated. This area of the market can be difficult to navigate alone. If you’d like help finding the lenders most likely to approve your application, or if you’ve already had an application declined, look for a specialist mortgage broker with experience dealing with non-standard properties.

Can you get a mortgage for a BISF construction?
Yes, but unfortunately, getting a mortgage for a BISF home can be extremely challenging because this type of steel-framed building is often considered more risky than others. A large number of steel-framed homes are British Iron and Steel Federation (BISF) properties.
Some specialist lenders will consider lending on BISF builds, but you may need to put down a larger deposit or pay a higher interest rate.
These lenders can be difficult to find without the help of a professional who knows this corner of the market well. Luckily, some brokers specialise in non-standard property types, and their knowledge, expertise, and lender contacts can boost your chances of getting a mortgage approval.
What about steel-framed extensions?
If you’re buying a standard property but it has a steel-framed extension, some lenders may be reluctant to approve your application. Specialist lenders will probably still want to conduct a thorough valuation, even though most of the property is traditionally built. The age of the extension may also play a role in lenders’ decisions.
If only part of the property has a steel framework—in this case, the extension—your choice of lenders and products might be wider than for somebody buying a home with steel frames throughout.
How to increase your chances of getting your application approved
There are a few ways to improve your chances of getting a mortgage on a steel-frame property.
You might decide to:
Save a bigger deposit
Saving a bigger deposit is easier said than done, but it can improve your chances of getting the mortgage you need. Most residential mortgage lenders ask for a deposit of at least 10%. This means you may need an even larger deposit to buy a steel-framed home.
Generally speaking, the bigger your deposit, the more comfortable lenders are about approving your application. This is because it reduces the risk they’re taking and gives them some protection if things were to go wrong or you couldn’t afford your mortgage payments.
Improve your credit rating
If you’re able to improve your credit rating before applying for a mortgage, this could make it easier to get the loan you need. Unfortunately, building your credit score isn’t an overnight process, and it can take a number of months.
Here are a few steps that could help you improve your score:
- Make existing debt payments on time and in full.
- Settle any debts you’re in a position to clear.
- Check your report with the three main credit referencing agencies (Experian, Equifax and TransUnion) to see if there are any inaccuracies.
- Let the referencing agencies know if you spot any mistakes.
- Register to vote on the electoral roll.
- Avoid making any unnecessary credit applications.
If you’ve struggled with debt in the past and your credit score has been affected, getting a bad credit mortgage may be possible.
Use a mortgage broker
A mortgage broker can help you overcome home-buying obstacles and get your loan. They’ll know the property market inside out and can compare hundreds of different lenders and mortgage deals to find the right one for you.
Your mortgage advisor will also know which lenders are least likely to approve your application based on your circumstances. With this knowledge, they can help you avoid damaging your credit score with a rejected application.

The importance of paying for a building survey
It’s a good idea to pay for a thorough building survey before making an offer on a steel-framed property. Since this type of property is considered ‘non-standard’, a Level 3 home survey may be needed. Your surveyor will inspect the property and look for any issues that could affect its value and make it harder to resell in the future.
Not all steel-framed houses are built the same way, and some are considered less risky than others. If you’re lucky enough to be buying one that does well in the survey, this could make it easier to get a mortgage.
If you apply for a mortgage with a lender who’ll consider lending to steel-framed house buyers, they’ll usually carry out a thorough inspection of the property themselves, too. This can make the application process longer than it would ordinarily be, and there may be more admin involved.
