Lenders don't have a problem with social work. You're qualified, registered with Social Work England, and councils are always recruiting. What trips people up is everything around the salary: an ASYE contract that started six weeks ago, a market supplement, locum pay through an umbrella company, a fixed term contract with five months left. Each of those can get a flat no from one lender and a yes from the next.
We're Alexander Southwell Mortgage Services, a whole of market broker in Romsey, near Southampton, and our team has submitted over 2,500 mortgages. There's no special social worker mortgage with a magic rate. What matters is matching your income structure to mortgage lenders whose criteria fit it, and that can be worth tens of thousands in borrowing.
Over 90% of our clients pay no broker fee, and we'll tell you before we apply if a lender is likely to get twitchy. Below: how lenders treat council and agency pay, a calculator, a worked example and answers to the questions we hear most.
You don't always need months of payslips. Some lenders will use the salary on a signed council contract if you start within a few months, and a few are happy with one payslip, so you aren't stuck waiting for probation to end.
Paid PAYE through an agency or umbrella company, lenders typically want around 12 months of track record. Through your own limited company, some will annualise your day rate like any other contractor.
Three or four days a week, or a shared team manager post, is ordinary employed income to nearly every lender, worked out pro rata. Regular sessional or out of hours pay can often be added on top.
Several lenders will use the salary on a new contract before you start. If you already own, we'll weigh porting your fixed rate against an early repayment charge, and search the market when your deal ends.
Alongside the right lender, these routes can get you moving with a smaller deposit.
Every lender wants to know what you earn and how sure they can be it carries on. A salaried council post is easy. Everything else depends on which bits of your pay a lender will count.
Council pay grades, from ASYE to team manager
Most council posts sit on the national pay spine, which rose 3.3% from April 2026. Roughly, newly qualified roles start in the mid to high £30,000s, experienced practitioners earn in the £40,000s and team managers £50,000 to £62,000, more with London weighting.
Overtime, standby and market supplements
Lenders class these as variable income, usually averaging 3 to 12 months of payslips and using some or all of it. This is the bit that trips people up, because supplements and retention payments often get treated like a bonus.
Essential car user allowance
Many lenders ignore it because it covers motoring costs, and a few may include it. It's rarely a deal breaker, but on a tight case don't build your budget around it.
Agency and locum day rates
Some lenders treat limited company locums as contractors. TSB and Skipton Building Society, for example, annualise a day rate as rate x 5 days x 46 weeks, so £250 a day becomes £57,500 a year.
Fixed term and interim contracts
Accord Mortgages, for instance, will consider fixed term contract income with 12 months left to run or a 12 month record of contract work. Other lenders want proof it has been renewed before.
Pension, student loan and registration
Your pension contribution (6.5% on £29,001 to £47,300 in 2026/27) doesn't cut the gross figure. A Plan 2 student loan on £40,000 is about £80 a month of outgoings. The £122 Social Work England fee is too small to matter.
A team manager eight years in post will probably be fine with their own bank. Three months into an ASYE or on a locum contract, you may not be, and the bank won't tell you who would have said yes.
We know which lenders get council pay. Some are relaxed about new contracts, some count overtime properly and some suit limited company locums.
We get the right income counted. We check your payslips first, work out what each lender would use and package your mortgage application so the underwriter sees a clear picture.
Most cases pay no broker fee. The lender pays us on over 90% of applications. It's £299 on mortgages under £100,000, and complex or adverse cases can cost up to £995.
We fit around your caseload. Phone or video when you can actually talk, and we chase the agent, solicitor and lender so you don't have to between visits.
Add your salary, any regular extras and how much of them a lender might count. Limited company locums can add a day rate, which is annualised the way some lenders do it.
This calculator is for illustration only and is not financial advice or a lending decision. Lenders use their own affordability models, so what you could borrow may be lower or higher.
Your home may be repossessed if you do not keep up repayments on your mortgage.
A simplified illustration, not a real client.
The buyer: a children's locum on £260 a day through her own limited company, taking about £40,000 in salary and dividends. She has £20,000 saved and needs £240,000 for a £260,000 house.
A lender using accounts: 4.5 times £40,000 is about £180,000. Nowhere near enough.
A lender using her day rate: £260 x 5 x 46 is £59,800. At 4.5 times that's around £269,100, so £240,000 could be within reach, subject to affordability and credit checks.
The catch: day rate lenders usually want about 12 months of contract history without long gaps. A month after going locum, accounts would have been her only route.
The point: same person, same income. The only difference was which lender looked at it, and that's the part a whole of market broker controls.
Here's what we do in the situations we see most.
First time buyers with a 5% deposit
A small deposit is normal. Plenty of lenders offer 5% deposit mortgages, and first time buyers in England pay no stamp duty on the first £300,000 of a home up to £500,000. Check yours on our stamp duty calculator.
Key worker priority for First Homes
Councils stopped being required to deliver First Homes in 2024, so supply is patchy, but where they exist councils can put key workers first for the first three months. Shared ownership is the other route.
Contractor routes for limited company locums
A lender that understands contractor mortgages usually beats one that only reads accounts. We'll check which gives you more.
Moving for a new post
Get a mortgage in principle before you view, especially if you're house hunting from a distance.
Credit blips and missed payments
An old default doesn't rule you out, and some lenders care more about the story than your credit score. Check your credit file, then talk to us before applying. A fee may apply here.
Remortgaging when your fixed rate ends
Don't just accept the first product transfer. We compare the market for your remortgage, including lenders that might now count overtime or a pay rise you didn't have when you bought.
Full PDF downloads, not screenshots of your banking app.
Everyone: photo ID, proof of address, three months of bank statements, proof of deposit and details of credit commitments.
Council staff: three payslips (more if we're using overtime), your P60, and your contract if it's new or fixed term.
Agency and umbrella locums: 12 months of payslips, P60s and your current assignment contract.
Limited company locums: a contract showing your day rate, your contract history and usually two years of accounts or tax calculations.
