CIS New Build Mortgage

David Sharpstone explains how the new build mortgage process works for CIS workers.

Is it harder to get a mortgage on a new build property for a CIS worker?

The rules for getting a CIS mortgage on a new build property are exactly the same as for a mortgage on a second-hand property.

What also has to be factored in, because it is a new build, is the amount of deposit. As always, you will need to demonstrate your income, using normally your last three months CIS payslips – but with a new build you may also need a slightly bigger deposit.

Some mortgage lenders, in particular if it’s a flat, would want a 10% or a 15% deposit – or even more in some cases.

It’s less restrictive on a house, and more and more lenders can do that with a 5% deposit, especially since the Help to Buy scheme ended a couple of years ago. So I would say it’s a little bit more difficult if lenders want a higher deposit.

How long does the new build application process take for a CIS worker?

It takes between 10 and 15 working days to approve the mortgage. The lender needs time to inspect the CIS payment and deduction statements, validate the income on the bank statements and do their own enquiries. That’s also the same timescale as buying a secondhand property as well.

Then we have the legal process. As a mortgage advisor, I’m not legally trained, but I’ve experienced the process hundreds of times over the last couple of decades for my clients.

That normally takes anything from four weeks to two or three months.

What are the eligibility criteria for a CIS worker to get a mortgage on a new build property?

If you’re paid through the CIS scheme and you want to buy new build property, first of all, you need to make sure you’ve got a minimum of three months of CIS payment and deduction statements. Make sure you have the 20% deduction and not the 30% deduction – the 20% tax indicates that you’re fully CIS registered. 30% is an emergency tax that applies when you haven’t been fully registered.

You would need to have a minimum of 12 months working in the construction industry. You wouldn’t be able to go from being a butcher four months ago and then straight into working in construction, for example. You need that track history.

How is affordability calculated for a CIS worker on a new build property?

The mortgage lender would normally look at either the last three months or the last 12 months CIS payment and deduction statements.

If they’re looking at the last three months, they’ll take the average and annualise that figure. Of course, if they’re looking at 12 months, that’s already the annual figure.

Then, they have to factor in other things. Quite often new builds have estate charges or service maintenance charges. That’s factored in as a monthly ongoing commitment along with any other financial commitments you may have, such as loans, car finance, credit cards, Klarna and PayPal payments.

Some commitments don’t appear on your credit file – such as looking after children or vulnerable adults. That’s all factored in when a mortgage lender calculates how much you can borrow using your CIS income.

What deposit do I need for a new build property as a CIS worker?

The minimum deposit is 5%. However, that can be impacted if you’re buying a flat. A new build flat will often need a minimum of a 10% deposit, and in some cases, maybe 15%. It just depends on the mortgage lender.

On a new build house, more and more lenders now accept CIS income and a 5% deposit.

There are exceptions to that – it might also depend on your credit profile. If it’s not a great credit profile, a 15% deposit would get you over the line.

How much can I borrow for a new build as a CIS worker?

It’s calculated using the gross income from your CIS payment and deduction statements, and then putting that into the mortgage lender’s calculator.

These calculators are all different from lender to lender, but generally speaking, you can typically borrow between four and 5.5 times your income.

If there’s a second person on the mortgage application, their income is added into the mix as well. You might get less than four times the total if you’ve got lots of financial commitments, or it might be closer to 5.5 times if you’ve got a very strong income with no commitments.

If you’re reading this as a Construction Industry Scheme (CIS) contractor, then you or your partner are probably struggling to find a mortgage right now. We can help.

What schemes are available for CIS workers for a mortgage on a new build property?

The most popular one at the moment is the shared ownership scheme, which is part-buy, part-rent.

There’s also the JBSP, which is Joint Borrower Sole Proprietor. It’s not a scheme as such, but it’s a different way to buy the property. It lets you add an extra person onto the mortgage application to boost the borrowing, but without them actually appearing on the deeds with the Land Registry [information correct at the time of recording in April 2025].

Can I get a mortgage as a CIS worker on a new build with bad credit?

Yes, there are options available, but you will need to put down a minimum of a 15% deposit.

There are lenders that can work within those parameters, taking your gross income from your CIS payslips to calculate what you can borrow.

How does a CIS worker remortgage work on a new build property?

It’s the same process as usual. If you want to move your mortgage from one lender to another because there’s a better deal, the new lender will want to inspect your CIS payment and deduction statements.

Again, it depends on the lender in terms of whether that’s three months or 12 months – then they’ll work out how much you can borrow from your gross income.

It’s the same as going to a mortgage lender in the first instance. It doesn’t matter that you’ve already got that mortgage – they need to make sure you can continue to afford to do so.

It would be lovely if it were just based on making all those monthly payments for the last two or five years, so there’s no need to demonstrate affordability. But no, it’s exactly the same as when you bought that property in the first instance.

What are the pros and cons of new build mortgages for a CIS worker?

The main benefit of a new build is you’re buying a property that is ready to move into. It doesn’t need any additional work. If you have no interest in making a mess in your home, or you don’t have the funds to buy property and renovate it, a new build would be a great solution.

The downside to new build properties, in my opinion, is that they are typically a bit smaller than properties built 30 or 40 years ago. Sometimes freshly built properties can have snagging issues, and there might be a period of time where the builder is coming back to correct issues with the property. That’s generally to be expected.

But reputable house builders will build that into their contracts – that they will come back to address the snagging on the property: just fixing the little things that get spotted here and there.

Properties also take time to settle and dry out. Sometimes little cracks appear that aren’t necessarily structural, just in the plaster.

How can a mortgage broker help a CIS worker?

If you’re a CIS worker looking to buy a new build property, in my view, you should speak to a mortgage broker. Not only have we got the lending criteria for CIS subcontractors to deal with, we’re now adding in the lending criteria on new build.

The size of deposit needed will vary from lender to lender, as will the criteria. We’ve got so many different factors to put into the mix to get the right mortgage for your circumstances. A mortgage broker with specialist knowledge will be able to figure that out pretty quickly – rather than you having to go to every single mortgage lender on the high street trying to work it all out for yourself.

YOUR PROPERTY MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE.
