Before you remortgage, it helps to understand whether the new payment would still feel comfortably affordable once your real-life bills, debts and day-to-day spending are included.

Featured insight
Ensure your new payment is comfortably affordable.
When you apply to remortgage, affordability is usually assessed using your income, outgoings and employment security, and you will often be asked for documents such as bank statements and payslips.
Many homeowners feel unsure at this stage, especially if costs have changed recently or money already feels stretched. This page is general information only, designed to help you understand the kinds of checks lenders commonly make and the points you may want to think through before applying.
The ten budgeting checks
1) Build a realistic monthly budget based on recent months
Avoid guessing. Use your last 3 to 6 months of bank statements and bills to understand your true spending across essentials and day-to-day costs. Looking at a longer period gives a clearer picture of what feels affordable across the year, not just in a quieter month.
For some homeowners, reviewing their budget is the first step before exploring whether a remortgage could help improve monthly affordability, depending on their situation.
2) Consider whether the payment would still feel manageable if things change
Think beyond today. Consider whether your budget would still work if interest rates rose or household costs increased. Lenders often look at how resilient your budget is over time, not just whether it works today.
In some cases, a remortgage may help reduce or stabilise payments, but it depends on your current deal, costs and overall circumstances.
3) List all committed outgoings, costs you cannot easily pause
Include loans, credit cards, car finance, childcare, insurance, subscriptions and regular bills. These are costs already committed before everyday spending, and lenders take them into account when assessing affordability.
If committed costs feel high, some homeowners explore whether restructuring borrowing, such as a remortgage, could help, but this needs careful consideration of the full cost.
4) Check whether debt repayments and smaller spending are easy to overlook
Things like BNPL, subscriptions or small direct debits can quietly build up. Lenders often review bank statements in detail, so overlooked spending can affect how your affordability is assessed.
For some people, reviewing all spending helps clarify whether a remortgage could simplify or consolidate costs, depending on suitability.
5) Check whether your budget still leaves a comfortable buffer
After essentials and committed costs, consider what is left. A budget with no breathing room can become difficult if anything changes.
Some homeowners review their buffer to see if adjusting their mortgage, for example through a remortgage, could improve monthly flexibility, but it depends on fees and individual circumstances.
6) Plan for known upcoming cost increases
Think ahead, childcare changes, insurance renewals, energy costs or commuting. Mortgages are long-term commitments, so planning ahead helps ensure your payments remain manageable.
In some situations, reviewing options such as a remortgage can form part of longer-term planning, but it should be assessed alongside all future costs.
7) Factor in remortgage costs and any early repayment charges (ERCs)
Switching can involve legal fees, valuation costs and potential penalties. A deal that looks cheaper monthly may not always be better overall once costs are included.
A remortgage can help in some cases, especially where a more suitable deal is available, but it is important to weigh total costs, not just monthly savings.
8) Make sure your income is clear and can be evidenced
Lenders typically require payslips, bank statements or accounts if self-employed. Lenders can only use income they can verify, and may average or adjust it.
If your income has improved or become more stable, it may open up additional options, including remortgage opportunities, depending on your circumstances.
9) Review your bank statements and credit history carefully
Your credit profile and spending patterns matter. Credit history can affect both approval and the range of options available.
For some homeowners, improving their credit profile can lead to better remortgage options, but outcomes vary depending on the full picture.
10) Make sure the payment feels right for your life, not just what is possible
Just because you can borrow a certain amount does not mean it is the right fit. Affordability is not just about approval, it is about long-term comfort.
A remortgage can sometimes help align your mortgage with your current needs, but the right option depends on your personal situation and preferences.
