How Working from Home Affects Your Mortgage
Updated 13 April 2026
If you work from home or run a business from a residential property, it is worth understanding how this can affect a mortgage application, an existing mortgage, or the terms your lender expects you to meet. For most people working remotely at a desk, there is no impact at all. But if your home doubles as a salon, studio, workshop or treatment room, lenders, surveyors and insurers may view the property differently. This guide explains where the lines fall and what you need to consider. Mortgage One can advise on how your working arrangements fit with lender criteria and help you find the right mortgage for your circumstances.
Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

When Working from Home Does Not Affect Your Mortgage
If you are an employee working remotely from a laptop or desktop at a home desk, this will not affect your mortgage. The property remains entirely residential in character, and lenders do not need to be notified. This applies whether you work from home full-time or on a hybrid basis.
The same generally applies if you are self-employed and your work is desk-based, provided you are not receiving clients at the property, storing significant commercial stock, or making physical changes to the building to accommodate business activity. A freelance writer, a software developer or an accountant working from a spare bedroom is using the property residentially, and lenders treat it accordingly.
When Business Use Could Affect Your Mortgage
The position changes when a property is used for commercial activity that goes beyond desk work. Examples include running a home beauty salon or treatment room, operating a hairdressing or barber business, teaching classes or holding therapy sessions with clients visiting the property, using a garage or outbuilding as a workshop or studio, childminding, or storing significant quantities of commercial stock.
Home-based beauty and wellness professionals are a good example of where this arises in practice. A therapist offering treatments from a dedicated room at home, such as Skin by Léa, operates a legitimate business from a residential property. The same applies to personal trainers with home gyms, music teachers with soundproofed studios, and dog groomers using a converted garage. In each case, the key question for lenders is whether the business activity materially changes the character of the property.
This does not mean you cannot get a mortgage or that your existing mortgage is at risk. It means you need to understand what your lender requires and, if you are buying, ensure the property is assessed correctly from the outset.
What Lenders Look For
Lenders assess whether a property is genuinely residential or whether the level of business use tips it into mixed-use or semi-commercial territory. The main factors they consider are the proportion of floor space used for business, whether clients or customers visit the property, and whether any structural changes have been made to accommodate the business.
Floor space.
Most lenders apply an informal threshold of around 30% to 40% of the total floor area. If the business occupies less than this proportion, the property is usually treated as residential. If more than 40% is given over to commercial use, some lenders may reclassify it as mixed-use, which could require a semi-commercial mortgage with different rates and criteria.
Client visits and footfall.
A home-based business that generates regular client visits, deliveries or vehicle traffic may attract more scrutiny from a lender or surveyor than one that operates quietly from a single room. This does not automatically prevent a standard residential mortgage, but it is something lenders and their valuers may flag.
Structural changes.
If a room, garage or outbuilding has been converted specifically for business use, particularly with separate access, signage, or commercial-grade fittings, lenders are more likely to view the property as mixed-use. Conversions that could be easily returned to residential use are generally less of a concern than permanent structural alterations.
If you are unsure how a lender would view your property, a broker can assess the situation before you apply and identify lenders whose criteria are most compatible with your setup.

Notifying Your Lender
If you have an existing residential mortgage and you start running a business from the property, you should notify your lender. Most residential mortgage contracts include a condition that the property is used as a private dwelling, and some explicitly prohibit business use without prior consent. Failing to notify your lender could put you in breach of your mortgage terms.
In practice, most lenders will grant consent for small-scale, low-impact home businesses without changing the mortgage product. If the business use is more significant, the lender may ask for more information or, in some cases, require you to move to a different product. The important thing is to check and get confirmation in writing rather than assume consent.
Insurance, Planning and Legal Considerations
Beyond the mortgage itself, running a business from home raises several practical considerations that can affect your application or your existing property arrangements.
• Buildings and contents insurance. Standard home insurance policies typically exclude business activity. If you are running a business from home, you may need to extend your home policy or take out separate business insurance. Lenders require adequate buildings insurance as a condition of the mortgage, so it is important that your cover reflects how the property is actually used.
• Public liability insurance. If clients or customers visit your home, public liability insurance is strongly advisable. Some professional bodies require it as a condition of membership. This is separate from your buildings and contents cover.
• Planning permission. You may need planning permission if you are making structural changes to accommodate a business, if the business generates significant traffic or noise, or if you are changing the use class of part of the property. Your local planning authority can advise on whether your intended use requires consent.
• Restrictive covenants. Some property title deeds contain covenants that prohibit or restrict business use. These are separate from your mortgage terms and are binding regardless of what your lender permits. Check the title deeds or ask your solicitor before starting a home business.
• Business rates and council tax. If part of your home is used exclusively for business, your local authority may assess business rates on that portion while you continue to pay council tax on the remainder. This can also have capital gains tax implications when you sell the property. You should discuss this with a qualified accountant.
The mortgage protection and insurance page on the Mortgage One website covers the main types of insurance relevant to mortgage borrowers, including buildings cover and life insurance.
Self-Employed Income and Mortgage Applications
If you are self-employed and work from home, your income will be assessed in the same way as any other self-employed applicant. Lenders will look at your SA302 tax calculations, business accounts, and bank statements to establish your average income over two to three years. The fact that you work from home rather than rented premises does not change how your income is assessed.
What can differ is how the property is valued and classified, which is the focus of this page. For a full explanation of how lenders assess self-employed income, including sole traders, limited company directors and contractors, see the self-employed mortgages guide on the Mortgage One website.
If you are buying your first home and plan to work from it, the first-time buyer mortgage guide explains the general process, deposit requirements and what to expect from lenders. Downloading your credit report before applying is also a useful step, as it allows your broker to identify any issues early and match you with the right lenders.

FAQs
1. Do I need to tell my mortgage lender if I work from home?
If you are an employee working from a laptop at a desk, you generally do not need to notify your lender. If you are running a business from the property, particularly one that involves client visits, stock storage or structural changes, you should notify your lender and get written consent.
2. Can I get a standard residential mortgage if I run a business from home?
In most cases, yes, provided the business use does not dominate the property. Lenders typically apply a threshold of around 30% to 40% of floor space. If business use exceeds this, a semi-commercial mortgage may be required.
3. Will a home salon or treatment room affect my mortgage application?
It can, depending on the lender and the scale of the setup. A dedicated treatment room in a residential property is common and many lenders will accept it, but the surveyor may comment on it in the valuation. A broker can identify lenders whose criteria accommodate this type of use.
4. Do I need planning permission to run a business from home?
Not always, but you may need planning permission if you are making structural alterations, changing the use class of part of the property, or if the business generates significant noise, traffic or disturbance. Check with your local planning authority.
5. Does working from home affect my home insurance?
Standard home insurance typically excludes business activity. If you run a business from home, you may need to extend your policy or take out separate business insurance. Lenders require adequate buildings cover as a mortgage condition, so this matters.
6. Will I pay business rates if I work from home?
You may pay business rates on the portion of your home used exclusively for business. You would continue to pay council tax on the residential portion. Contact your local Valuation Office Agency for an assessment.
7. Does running a business from home affect capital gains tax when I sell?
It can. If part of your home has been used exclusively for business, that portion may not qualify for the principal private residence relief that normally exempts your home from capital gains tax. This is a question for a qualified accountant, not a mortgage adviser.
