Converting commercial property to residential isn’t always the easiest pursuit, and very much depends on the type of commercial property you’re looking to develop.

Given the rapidly changing face of the UK high street and commercial property in general, thanks to events of the past year or so, there has been a huge surge in demand for converting this type of property.

There is an argument to be had that commercial property was, by and large, changing quickly anyway. Shops, industrial units and other types of business premises had been changing use slowly but surely anyway and taking a walk down your local high street will give you an indication of how popular this is already.

Changing the use of commercial property into residential is lucrative too. When done correctly in the right area, there’s plenty of money to be made wither by converting the property and selling it straight away or converting it and renting it out as a landlord. This decision will have implications if you’re looking for finance too, as we’ll explain in greater detail.

What is planning permission?

property mortgage for residential and commercial landlordsWhen you’re looking to convert any type of property, you’ll need the nod from the local authority to do so. This is known as planning permission and in most circumstances, you’ll need to submit your plans for converting the commercial property, residential property or any significant conversion for approval.

On most occasions it’s fairly straight forward to get planning permission for your property or your development, however, it’s always worth checking with your local authority and getting in touch with their planning department early.

Do I need planning permission?

The short answer to that is, probably, yes. There are some very specific circumstances which you may not need to apply for permission when converting your property, however, these are quite specific and limited. It’s worth talking to your local authority beforehand.

There are things known as Permitted Development Rights (PDRs) which are granted by Parliament rather than local authorities, however, the chances that you’ll be able to use this are slim.

Step One

You’ll need to check what type of property it is and whether it’s eligible to be converted into residential property. The vast majority of commercial properties are eligible for a residential conversion, however, there are circumstances where they’re not. If it’s in a conservation area, for example, a national park, an area of natural beauty or listed buildings. Before you purchase the commercial property or set concrete plans it’s worth checking that these exceptions don’t apply first.

Step Two

You’ll need to figure out what type of activity the commercial property is used for. This should be a number of things. Shops, for example, might be categorised as Class A. The list of classes is:

  • Class A – This class is for shops, restaurants, and businesses that provide professional services
  • Class B – This class is for offices, storage facilities and warehouses
  • Class C – This class is for residential properties, and places of habitation, for example, hotels and care homes.
  • Class D – This is for miscellaneous commercial properties such as schools, doctor’s surgeries, cinemas, and leisure facilities.

When you apply for planning permission, you’ll essentially be applying to change the class, and use, of the building from commercial to residential.

Step Three

You’ll need to figure out if you need planning permission. It’s true that when you’re planning to convert some types of commercial property you don’t technically need to apply for planning permission, however, these are only in very specific circumstances and you should assume that you do need it and should contact the local planning department to seek their advice.

Step Four

Now would be a good idea to sort out your finance or mortgage situation. There are a number of options, such as a mortgages designed for a landlord, or bridging finance whilst you convert the building before arranging a mortgage or mortgages.

We have an experienced team of brokers that can act as an intermediary on your behalf as a landlord or developer and confirm your options with you, which could include mortgages.

Step Five

Finding the right property that meets all of these criteria is key. Not all conversions will be appropriate for your plans. An office building, for example, may be in a key location but is it a listed building? Commercial property comes in many forms and, for example, industrial property may be harder to renovate or use for conversion.

You need to figure out what you’re looking to do with the property in terms of are you looking to immediately use the property for conversion and then sell? Or are you looking to keep hold and use it for residential purposes and rent them out?

These questions will inform your decision of what type of commercial property will suit your needs.

How to change use from commercial to residential

Primarily your budgeting will be key for converting a commercial property or premises. There will be, for example, solicitors’ fees, planning costs, architect costs and building costs. It’s crucial to have some kind of plan not only so that you know your timescales and the amount of money you’ll need, but because if you seek finance at a later point most lenders will want to see this level of detail.

Once you’ve sourced the commercial property you’re looking at for development, it’s then time to get in touch with the relevant solicitors and planning departments to see what level of detail you’ll need to provide to be approved, and then to get in touch with an architect who can develop the plans for you, before sourcing a builder.

Do I need Planning Permission under Permitted Development?

The Town and Country Planning (General Permitted Development) (England) Order 2015 states that you don’t require planning permission for “The enlargement, improvement or other alteration of a dwellinghouse.”

The general advice is, however, to ensure that you speak to the planning department at the local authority first.

Commercial to residential conversion cost

The cost of development for a commercial property can range hugely. If, for example, you’re developing a small office block then there are things to consider such as fire regulations and the need for each flat or dwelling to have its own lockable door. These regulations are usually best discussed with a solicitor, and a reputable builder can help give you a better idea and potentially quote you a rough cost.

Are there any grants for converting commercial property to residential?

In some very specific and strict circumstances you could possibly eligible for a grant from the local authority if the property could be classed as an empty property.

This is at the discretion of the local authority and there are strict terms, but you can usually find out if the property is empty or abandoned and therefore possibly eligible via the land registry website.

Work out office to residential conversion cost per square foot

You can use a quite simple mathematical process to work this out, and some lenders may ask you for your projected costs in this way. First, you’ll need to work out the Gross Internal Area (GIA) in square feet. You’ll then need to take away lobbies, stairs, toilets, etc that are required to stay and take it away from the GIA, which will give you a Net Internal Area (NIA).

Work out how much of your space is useable, so that’s how much can actually be used for flats and dwellings, and then work out how big you want your flats to be. Take your GIA and divide it by your costs, and then deduct your profit margin and this should give you a good idea.

Different ways to fund the conversion

There are a number of ways you can fund a housing project or commercial property of this type, such as a mortgage broker or bridging loan.

Bridging loans

Bridging loans are a type of loan that are designed to be short term. This could cover, for example, the initial cost of buying the land and materials before then agreeing a mortgage for your commercial property conversion at a later date. This type of loan is ideal for developers who need quick access to initial funding and our brokers can talk you through the process.

Self funded

If you have deep pockets and a good supply of cash at hand then this can be a good option, however, it’s probably worth keeping finance options open for unforeseen costs that can arise through the project.

Property mortgage

Some lenders may be willing to fund your entire project with a mortgage if you’ve got a decent sized deposit and a good track record as a developer, however, different lenders have different requirements so it’s advisable to speak to a broker or intermediary who can discuss this with you and let you know what you’ll need to be approved.

Frequently Asked Questions

You may have heard about bridging loans in the context of property investment or moving house, but what exactly are they? Basically, bridging finance is a type of short-term loan that allows a buyer to purchase a property before their existing home or investment property is sold. As the name suggests, it ‘bridges’ the funding gap in the lag between purchase and sale – offering rapid access to the necessary purchase funds for a brief period of time.

Borrowers can access from £5,000 to £250 million, depending on applicant status, the value of the property and other lender criteria. Higher lending amounts are typically reserved for borrowers who can put up several properties as security. Quotes are provided on a Loan to Value (LTV) of 65%-80% in most situations.

Bridging loans can be used in a number of situations. For example:

  1. When people are moving home in a chain, with a gap between completion dates (e.g. needing to pay for the new property before receiving funds on the completed old property).
  2. When property investors or private buyers renovate a home and want a rapid sell-on.
  3. When an individual is looking to buy a property at an auction.
  4. When property investors and developers are looking to pay a tax bill
  5. When buyers want to secure finance against an uninhabitable property.

This type of finance can be used by homeowners, landlords and property developers alike.

The bridging finance market has grown rapidly, with a number of small and focused lenders now on the market, catering for specialist property finance needs. The market has changed because large high-street lenders have become less willing (and sometimes less able) to lend ever since the financial crisis of 2008.

As to whether a bridging loan for property development, auction purchase or private home buying is a good idea, it depends on a variety of factors. Bridging loan requirements vary by lender, but each will have certain common features that need to be considered.

The most notable feature of this type of finance is that the interest rate is likely to be high. At the same time, there are typically high administration fees applied to the loan. Because of this, it is essential to proceed very carefully and with a full view of the facts. Borrowers have been burned by this type of loan in the past, in instances where transactions have fallen through, or where lenders have turned out to be unscrupulous and untrustworthy.

Benefits of instant bridging loans

1. Rapid access to money
2. Ability to borrow large sums – often up to £250 million depending on applicant status
3. Options for flexible borrowing.

Possible downsides of bridging loans:

1. Failure to understand the unique features of these loans can result in financial risk
2. Bridging finance is secured against your property; meaning it can be sold if you can’t meet the repayment terms
3. A costly option with fees and higher interest

Bridging finance interest rates will vary by lender. However, interest costs of 1.5% a month are not unusual, which can equate to an annual percentage rate of 18%.

Bridging loans may have fixed or variable interest rate features. Fixed interest rates are ideal for customers who want stability, as they offer the same amount of interest for the duration of the term. The rate is pre-agreed, but there may be a premium for this security.

The other choice is to have a variable rate bridging loan which can change with the base rate. However, you can save money if the base rate decreases. Borrowers who are less concerned about security sometimes prefer the variable rate option if they believe that the financial markets will travel in their favour. Knowledge and market insight is required here, along with a thorough understanding of personal risk tolerance. If interest rates appear to be rising, most customers will choose the fixed interest rate to lock it in and avoid further increases in the event of a base rate rise.

Bridging loan periods tend to be for several months and there are usually different options for paying the interest portion.

Monthly repayments

The customer repays the interest every month as a separate payment, rather than adding it to the outstanding balance

Rolled-up bridging finance deals

The compound interest is calculated monthly but added to the outstanding loan balance and paid together when repayment is due.

Retained interest

The monthly interest payment due is covered up to a predefined date so that the full sum is only repaid when monies are due.

As well as interest payments, there will be an arrangement fee for the set-up of the bridging loan, which is usually around 1-2%. A repayment fee for exit paperwork may also apply, along with valuation fees for the cost of the surveyor.

Remember, this type of finance is designed to be short-term. As soon as it extends beyond the agreed interim or bridging period, penalties can rapidly stack up. Typically, bridging finance is available for 1 – 18 months.

Yes, there are two broad types: closed bridging finance and open bridging finance.

With closed bridging finance you will tell the lender how you will repay the loan – with what funds and when. These loans usually complete within a few months and the clear exit plan is required as a lending condition.

Open bridge finance won’t usually need this type of exit plan, and it is typically the loan of choice when funds are needed urgently to complete a property transaction. No detailed plan is needed to explain how the debt will be settled, and the finance tends to be offered for up to a year. Of course, it’s important to note that interest will keep being applied throughout this period.

There are also first charge bridging loans and second charge bridging loans.

If you have a loan against a property which is already mortgaged, you’d take out a second charge loan. An example of this would be if you were planning to finance a property extension to improve the property. The categorisation tells the lenders who will have legal priority for repayment if the loan was unable to be paid off at the term-end.

First charge loans apply if the new loan is the first secured on the property.

Bridging loan requirements will depend on the lender. Often, lenders will require that:

Customers must also take out their property mortgage with them too, providing the bridge finance as an interim measure before the standard mortgage comes into play.

Property is put forward as security against the loan. Some lenders expect applicants to have more than one property in order to be eligible for their bridging finance products, but this will depend on the lender and the size of the loan.

Applicants show proof of income – although, interestingly, as loan interest isn’t repaid monthly, some lenders do not request this.

The applicant shows evidence of their property investment track record if they are planning to develop their purchased property.

The applicant can show a business plan if they are using the bridging loan for commercial purposes.

Development loans are another type of short-term property development loan. They are repaid in stages and calculated on the gross value of the development. Personal loans are another option, as are remortgages when timescales are more flexible and a long-term loan is desirable.

Use a bridge loan calculator
Ask for your lender to provide a tailored bridge finance example or illustration around your particular borrowing needs.
Think carefully about the type of bridging loan that you need – whether open bridge finance or closed bridge finance.
Know whether the loan is a first or second charge type.
Clarify whether the interest rate is fixed or variable.
Review products from several lenders.
Be clear on your security.
Read the small print!

Bridging loans are offered by banks, building societies, specialist lenders and brokers. They aren’t widely advertised and usually require a direct application by the customer to find out the product features and offers.

Once you have made an application, a decision will usually be made within 24 hours. The funds then will take around two weeks to be issued, including time for checks to be carried out, the valuation and the actual transfer.
