How Does Remortgaging for Home Improvements Work?

When you remortgage for home improvements, you are essentially replacing your current mortgage with a new, larger one. The difference between your existing mortgage balance and the new mortgage amount is released to you as cash, which you can then use to fund your renovation projects.

For example, if your property is worth 300,000 pounds and your outstanding mortgage is 150,000 pounds, you have 150,000 pounds of equity. A lender might allow you to borrow up to 80% or even 90% of your property value, meaning you could potentially release a substantial sum for improvements.

The process works as follows:

Most lenders are happy to lend additional funds for home improvements, as the work typically adds value to the property, which strengthens their security. You will usually need to tell the lender what the funds are for, and home improvements are generally viewed very favourably.

How Much Can You Borrow for Home Improvements?

The amount you can borrow when remortgaging for home improvements depends on several factors, including the value of your property, your existing mortgage balance, your income and your credit history.

Loan-to-value limits

Most lenders will allow you to borrow up to 85% or 90% of your property value when releasing equity for improvements. Some may go higher in certain circumstances, but you will generally get better interest rates at lower loan-to-value ratios. The most competitive deals are typically available at 60% LTV or below.

Affordability assessment

Lenders must ensure you can afford the increased monthly payments. They will assess your income, regular outgoings, existing debts and living expenses. Since the Mortgage Market Review, all lenders are required to carry out thorough affordability checks, and this applies equally when you are borrowing additional funds for improvements.

Income multiples

As a general guide, most lenders will offer between 4 and 4.5 times your annual household income. If you are borrowing jointly, both incomes can be taken into account. Some specialist lenders may offer higher multiples for higher earners or those with particularly strong financial profiles.

Practical considerations

While it can be tempting to borrow as much as possible, it is sensible to only borrow what you need for the planned improvements. Remember that any additional borrowing will increase your monthly payments and the total interest paid over the life of the mortgage. A detailed budget for your improvement project will help you determine the right amount to borrow.

It is also worth considering that the improvements themselves may increase the value of your property, which could improve your LTV ratio over time and potentially give you access to better rates when you next come to remortgage.

Which Home Improvements Add the Most Value?

Not all home improvements are created equal when it comes to adding value to your property. Understanding which projects offer the best return on investment can help you make smart decisions about where to spend your money.

High-value improvements:

Moderate-value improvements:

When planning improvements with borrowed funds, it makes sense to prioritise projects that will add value to the property. This way, your investment is working in two ways: improving your quality of life now and building equity for the future.

Bear in mind that the value added by any improvement depends on the local market, the quality of the work and how well the project suits the property. Over-improving a modest property in a lower-value area may not deliver the same return as similar work on a home in a higher-demand location.

Remortgage vs Other Ways to Fund Home Improvements

Remortgaging is not the only way to pay for home improvements, and it is worth considering all your options before deciding which route is best for your situation.

Remortgage (releasing equity)

The main advantage of remortgaging is that mortgage interest rates are typically the lowest available, often significantly less than personal loan rates. This makes it the most cost-effective way to borrow larger sums. However, you are securing the debt against your home, which means your property is at risk if you fail to keep up with payments. You will also be repaying the additional borrowing over the full mortgage term, which means you could pay more interest overall even though the rate is lower.

Further advance

Instead of remortgaging entirely, you could ask your existing lender for a further advance. This keeps your current mortgage deal in place and adds a second portion with its own rate and terms. It can be simpler and avoids early repayment charges on your existing deal, but the interest rate on the further advance may not be as competitive as what is available from other lenders.

Personal loan

For smaller improvement projects, a personal loan can be a good option. Loans are unsecured, so your home is not directly at risk, and they typically have shorter repayment terms of one to seven years, meaning you pay off the debt more quickly. However, interest rates are higher than mortgage rates, especially for larger amounts.

Credit cards

For very small projects, a 0% purchase credit card could be useful if you can repay the balance within the interest-free period. This is only suitable for modest amounts and requires disciplined repayment.

Government grants and schemes

Depending on the type of improvements you are planning, there may be government grants or schemes available, particularly for energy efficiency improvements. It is worth checking what is currently on offer before committing to borrowing.

The right choice depends on how much you need to borrow, the interest rates available to you, and your personal comfort with securing debt against your property. A mortgage adviser can help you compare the total cost of each option.

The Remortgage Process for Home Improvements: Step by Step

If you have decided that remortgaging is the right way to fund your home improvements, here is what to expect from the process.

Step 1: Plan your improvements and budget

Before approaching lenders, have a clear idea of what work you want to carry out and how much it will cost. Get multiple quotes from contractors and include a contingency of around 10% to 15% for unexpected costs. This will help you determine exactly how much additional borrowing you need.

Step 2: Check your current mortgage terms

Review your existing mortgage to understand whether you are still within a fixed or discounted period and whether any early repayment charges would apply if you switched to a new lender. If early repayment charges are significant, it may be more cost-effective to ask your current lender for a further advance instead.

Step 3: Speak to a mortgage adviser

A whole-of-market mortgage broker can search across all available lenders to find the best deal for your situation. They will assess how much you can borrow, compare total costs including fees and charges, and recommend the most suitable option. Look for an adviser who is authorised and regulated by the Financial Conduct Authority.

Step 4: Make your application

Your adviser or lender will guide you through the application. You will need to provide proof of income, bank statements, details of your current mortgage and identification documents. The lender will carry out affordability checks and a credit search.

Step 5: Property valuation

The lender will arrange a valuation of your property to confirm its current market value. This determines your loan-to-value ratio and the amount of equity available for release.

Step 6: Legal work and completion

A solicitor or conveyancer will handle the legal transfer from your old mortgage to the new one. This typically takes four to eight weeks. Once complete, the additional funds will be released and you can begin your improvements.

Many homeowners start the remortgage process around six months before their current deal expires, as most lenders allow you to lock in a new rate well in advance. This gives you time to plan your improvements and have everything ready to go when the funds become available.

Important Considerations Before Remortgaging for Improvements

Before committing to a remortgage for home improvements, there are several important factors to consider to ensure it is the right decision for your circumstances.

Will the improvements add value?

Consider whether the planned improvements are likely to increase the value of your property by more than they cost. While not every improvement needs to deliver a positive return, it is reassuring to know that your investment is enhancing your asset as well as your living space.

Can you afford the higher payments?

Increasing your mortgage means higher monthly payments. Make sure you have stress-tested your budget to ensure you can comfortably afford the new payments, even if interest rates rise or your income changes. Lenders will carry out their own affordability assessment, but it is wise to do your own calculations too.

Planning permission and building regulations

Some home improvement projects require planning permission from your local council, and almost all structural work needs to comply with building regulations. Make sure you have the necessary approvals in place before starting work. Carrying out work without proper permission can cause problems when you come to sell or remortgage in the future.

Insurance considerations

Major improvements such as extensions or loft conversions will affect the rebuild cost of your property. You should inform your buildings insurance provider about any significant work and update your cover accordingly. Failure to do so could invalidate your policy.

Choosing the right contractors

The quality of workmanship on your improvements will affect both the value added and your enjoyment of the finished result. Take time to research contractors, check references and ensure they have appropriate qualifications and insurance. For larger projects, consider using contractors who are members of recognised trade bodies.

Tax implications

If you let part of your property or use it for business purposes, some improvements may have capital gains tax implications. It is worth taking professional advice if your property use is anything other than a straightforward residential home.

Taking the time to plan carefully and consider all these factors will help ensure that your remortgage-funded improvements are a success, both financially and practically.

Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There will be a fee for mortgage advice. The actual rate available will depend on your circumstances. Think carefully before securing other debts against your home.

Frequently Asked Questions

Yes, remortgaging to fund home improvements is one of the most common reasons UK homeowners switch their mortgage. You release equity from your property by taking out a larger mortgage, and the additional funds can be used to pay for renovation work. Most lenders view home improvements favourably as they typically increase the property value.

You will need enough equity in your property to cover both your existing mortgage and the additional borrowing. Most lenders require you to retain at least 10% to 15% equity after the remortgage. For example, if your home is worth 300,000 pounds, most lenders would cap your total borrowing at around 255,000 to 270,000 pounds.

Remortgaging typically offers lower interest rates than personal loans, making it cheaper on a monthly basis. However, because you repay a mortgage over a much longer term, you could end up paying more in total interest. For smaller amounts under 25,000 pounds, a personal loan with a shorter repayment period may actually cost less overall.

Yes, most lenders will ask you to state the purpose of the additional borrowing when you apply. Home improvements are generally seen as an acceptable and low-risk reason to release equity. Some lenders may ask for more detail about the planned work, particularly for larger amounts.

Many home improvements do increase property value, though the amount varies depending on the type of work, the quality of the finish and the local market. Extensions, loft conversions and kitchen renovations tend to add the most value. It is worth researching local property prices and seeking professional advice to understand the likely return on your specific project.

The remortgage process typically takes between four and eight weeks from application to completion. You can start the process up to six months before your current deal expires. Once the funds are released, you can begin your improvement work immediately.

Yes, although your options may be more limited and the interest rates higher. Specialist lenders cater to borrowers with adverse credit histories, and a whole-of-market broker can help identify the best deals for your circumstances. The amount of equity in your property and the severity of your credit issues will both affect the deals available to you.

You do not need planning permission in place before you remortgage, as the lender is primarily concerned with the current value and condition of your property. However, you should ensure you obtain any necessary planning permission and building regulations approval before starting the actual improvement work.

Yes, you can carry out DIY improvements using remortgage funds. However, for any work involving structural changes, electrics, gas or plumbing, you should use qualified professionals. Poorly executed work can reduce rather than increase your property value and may cause problems with insurance or future mortgage applications.

Yes, if you are remortgaging to a new lender, they will arrange a valuation of your property. This is based on the current condition before any improvements, so the valuation will reflect what the property is worth today. Some lenders use automated or desktop valuations, while others may send a surveyor to visit in person.

You can, but if you are still within your fixed rate period, you may face early repayment charges for switching to a new lender. These charges can be substantial, typically between 1% and 5% of the outstanding mortgage balance. An alternative is to ask your current lender for a further advance, which would not trigger early repayment charges on the existing deal.

It is common for improvement projects to exceed their initial budget. Building a contingency of 10% to 15% into your borrowing amount can help cover unexpected costs. If you run out of funds, you may need to consider a personal loan or credit card for the shortfall, as taking out another remortgage shortly after the first is not usually practical.

For standard residential homeowners, there are no specific tax benefits to remortgaging for home improvements. However, certain energy-efficient improvements may qualify for reduced VAT rates. If you are a landlord making improvements to a rental property, the mortgage interest may be partially deductible, though the rules have changed in recent years. Consult a tax adviser for guidance specific to your situation.

Yes, you can remortgage a buy-to-let property to fund improvements. Buy-to-let remortgages work slightly differently from residential ones, with affordability typically assessed on rental income rather than personal earnings. Improving a buy-to-let property can increase both its value and the rent you can charge, making it a worthwhile investment.

It depends on your circumstances. Remortgaging before improvements gives you the funds to pay for the work. However, if you already have savings to cover the costs, remortgaging after the improvements are complete means the property will be valued in its improved state, potentially giving you a lower LTV ratio and access to better rates. Discuss the best timing with your mortgage adviser.
