Garage Conversion Cost 2022: Ultimate Price Guide UK

A garage can be a perfect storage space if you have a large household. This is especially true if your attic already contains too many items and you need the extra space for all the memorabilia you do not want to throw out just yet. Also, your garage can be handy as an extra living space if your house feels cramped. Having visitors coming during the holidays or dropping in at odd times does not have to be frustrating anymore.

You can also turn it into any other useful space. It does not have to be a living space. Working from home is the trend these days and having a home office is convenient and cheap. If you have a means of converting your garage, it may be a practical solution to a space problem. The conversion is usually affordable and an option many homeowners often overlook. If the garage is not housing your car or serving as a useful storage area, consider converting it to that extra space you need.

This article discusses the current cost of garage conversions in light of the above. It also looks at the potential factors affecting the cost, the steps involved and finding a suitable garage conversion specialist. It also suggests how to save money on the conversion.

Current Cost of a Garage Conversion

The type and size of the garage determine the amount you spend on conversion. For example, converting a single garage of about 18 square meters may cost as low as £5,000.

You have the option of using an extension, but it’s more expensive. If you want to install a single-storey extension to your garage of about 18 square meters, it may cost as much as £18,000.

The following shows the potential costs of converting different garage types based on various budgets and the required time:

Garage Type Low-Cost  High-Cost Estimated Work Time
Detached double garage Between £45,000 and £56,000 Between £56,000 and £62,000 4 weeks
Detached single garage Between £30,000 and £38,000 Between £38,000 and £53,000 3 weeks
Attached double garage Between £20,000 and £25,000 Between £25,000 and £35,000 3 weeks
Attached single garage Between £13,500 and £17,000 Between £17,000 and £23,500 2 weeks
Integral double garage Between £9,000 and £11,500 Between £11,500 and £16,000 3 weeks
Integral single garage Between £5,000 and £7,500 Between £7,500 and £10,500 2 weeks

It costs more to convert bigger garages than the smaller ones. Another determining factor is whether or not the garage connects to your house. Also, the garage style plays a key role in the amount it costs to convert the garage. The integral single garage is the most affordable option. It costs only between £5,000 and £7,500 if you are working on a budget. If you want to splurge a little, you can add a few extra touches at a cost running between £7,500 and £10,500.

An integral double garage costs a little more. However, the cost depends on the type of work mapped out. A more budget-friendly conversion may cost you between £9,000 and £11,500. Extra touches may spike the cost between £11,500 and £16,000. If the garage is the attached type, it is more expensive to convert it than an integral-style type.

The budget for an attached single garage is between £13,500 and £17,000. The more expensive option is between £17,00 and £23,500. As mentioned, the bigger the garage, the more it costs to convert it. So, for an attached double garage, the cheaper option costs between £20,000 and £25,000, while the costlier option is between £25,000 and £35,000.

A detached garage, single or double, is the most expensive option because of the need to erect a standalone structure. Converting a detached single garage on a budget may cost between £30,000 and £38,000. A more expensive option may range between £38,000 and £53,000.

For a detached double garage, you may spend between £45,000 and £56,000 for the more affordable conversion. However, a more expensive conversion may cost between £56,000 and £62,000. Note that the bigger the garage, the longer it takes to complete the job, as the table details. While this may be true, a smaller garage needing extensive work may take longer to complete than a bigger one with minimal internal and external work.

There are different aspects of labour to consider. You will need an electrician, plasterer, painter, and other contractors. Each contractor charges a separate fee. A painter may charge about £150 to £200 per day, while an electrician may charge £230 per day. However, the amount you spend on labour can vary depending on the amount of internal work required on the garage.

Factors Affecting Garage Conversion Cost

One of the upsides of garage conversions is that you may not need to build an entirely new structure. You can work on what you already have and change it into the space you need. However, such a conversion may be more cost-intensive than erecting a new structure. So, consider the following factors before you put down numbers and make calculations.

  • Utility

Most garages already have electricity, so you may not have to install wires in the walls, and that usually,  is a cost-intensive venture. All you may need to add to the space are sockets and extra light fixtures. It does not cost much to install those, which may translate to reduced costs in the utility department.

However, if there were none, you may need plumbing and gas pipes in the space. Many homeowners do not equip their garages to be living spaces, so they do not bother installing these amenities. If the purpose of the garage conversion is to turn it into a living area, it will need plumbing and gas lines, which are expensive to install. You may spend up to £3,000, depending on the size and type of installation.

  • Doors

Replacing the garage door is one of the primary conversion steps to improve weather-sealing. Garage doors are not exactly weather-proof, so using the old ones is not advisable for safety and health preservation.

Nevertheless, you may not need to remove the door if you can find a suitable weather-sealing material to close any openings. The door may be one of the easiest conversions if the specialist determines to retain the old door and seal the openings.

Adding a window or two may be costly if you want that. It cost as much as £1,300. Installing brand new doors and windows may be necessary to change the look and feel of the garage, and this installation may cost a minimum of £500 for each window or door.

  • Wall Structure

The garage may need stud walls to create a new look and feel. The type of wall you select will determine the cost of materials and installation. You can opt for regular drywall and add insulation between pre-existing walls and new walls. Installing regular drywall materials and finishing are affordable, whether you are buying per sheet or square meter. So, you may want to consider using this option to save costs.

However, if you want a soundproof and energy-efficient option, it may cost a little more. There are no fixed prices for these walls, but your contractor is in the best position to suggest the most suitable option for your space. Note that the more privacy you desire, the thicker the walls must be.

  • Flooring

Flooring is also another vital aspect of garage conversion. Typically, a garage houses cars. If you do not store cars in it, other uses may affect the original floor. In other words, it may be necessary to refloor the garage, especially if there are oil or other stains.

The type of floor in the garage may also be inconvenient for a living area. It does not have to be about oil stains but the type of material used in the flooring. That may mean pouring new concrete and using a different finishing afterwards. Redoing the floor may have a starting cost of £1,000.

  • Additional Fees

If you are using a garage conversion specialist for the job, there may be extra charges to add to your budget. The same applies if you use an architect or hire someone to manage the project. Paying for the conversion out of pocket is an excellent idea, but not everyone can afford that while paying without any financial assistance. As a result, most people may resort to taking a loan.

Therefore, consider possible charges if you take a loan to finance the project. Not only are you considering the upfront loan fees but, more importantly, the accruing interests. The longer the loan period, the higher the interest to pay. The loan type will determine the repayment plan, but most will require monthly deposits, affecting your general lifestyle.

How to Save Money on a Garage Conversion Project

Converting a garage into a living space may seem financially daunting. If you look at the factors mentioned above, you may want to back out of the project. However, it does not have to cost as much as it appears. You can save money in several ways on the project. Let’s look at some of them.

  • Decoration Costs

If you are an enthusiastic DIYer or skilled in many things, you may want to do some decoration yourself and cut costs. The painting job can be expensive, but you can opt to do it yourself when the contractors leave at the end of each day. While it is a messy job and you may have little training, it significantly reduces the amount you pay for the project.

You can start small and as you become more confident, add a few decorative swirls if you are so inclined. Using wallpaper may be easier, so consider going for that option, especially if it means spending less on paint.

  • Labour Costs

A few aspects of labour can save you time and money. If you can, consider moving the furniture in the garage out before the contractors come. The longer they spend on the project, the more money you pay, especially if you are paying by the hour.

Since you need to empty the garage for work to commence, cut down the cost of labour by doing the work yourself. Getting someone to help makes the job faster, particularly if there is heavy lifting to do. You can also consider clearing the debris yourself.

Instead of waiting for the contractors to clear the site at the end of each day, offer to do the messy job. It may not be nice and may mean taking time off other chores, but you will save some labour money daily. Channel the money into something else or use it to pay for a more luxurious finish in your garage.

  • Finishing Costs

Speak with your contractor, project manager, or garage conversion specialist to find the best deals and discounts on parts required for the project. You may spend more on supplies if you leave the purchase of parts to the contractors. Therefore, look for stores with products you will need on sale or with discounts and make purchases before the project begins. Ask for a list of the required materials or go shopping with an expert.

What Is Involved in Garage Conversion?

There are several steps in converting a garage. First, you may want to speak with a garage conversion specialist to know your options. The specialist will assess your property, explain the options, and give the conversion options within your budget.

You will get the required planning permission and building regulations. Also, get design options so you can choose, and when you pick one, the contractors can follow the regulations to commence the project. The next step is to clean out the garage and install supports for the structure as work commences.

The installation and fittings will depend on the design of choice, but there will be gas, plumbing, and lighting installations. Then, the contractors will redo the walls and floor before removing the garage door to install one more suitable for the space.

Finding and Hiring a Garage Conversion Professional

An excellent place to start is to ask family and friends for recommendations. You can also ask neighbours who may have converted their garages recently. One or more of them may have recommendations, and you can begin your search from there.

Another option is to search through a service marketplace like Bark to find garage conversion specialists within your locality. You will find several specialists and easily compare prices, services, and nearest locations. It is always advisable to use trusted merchants and marketplaces to find reliable vendors and traders. That way, you avoid fraudulent companies and traders.

Ensure the Professional Is Who You Need

The specialist must give you a written quote. It helps you know if their price fits in your budget so you can make other plans if necessary. They must also state the estimated time within which they can finish the garage conversion. Everything must be written down; a verbal agreement is not enough, especially when you are entrusting a significant amount of money to someone else.

Check past testimonials and projects they have previously handled. These will inform you whether or not they are the right fit for the project you have in mind. Verifiable clients go a long way in boosting your confidence, so it helps if you can more than one to back the specialist’s claims.

Additionally, the specialist must have insurance appropriate enough to cover every aspect of the project, including the workers and you. A lack of insurance should be deciding factor because it means you are liable for any damages incurred during the project. You can also use bark for other services like tree removals.

Final Checklist

Deciding to convert your garage into a living or workspace is not a small undertaking. You must carefully consider every aspect of the job before commencing. However, if you have come to the point where you are sure a garage conversion is what you need, especially if the space is not currently useful, below is a final checklist to tick before contractors begin work:

  • Contact the appropriate authorities to determine whether or not you need planning permission. If you live in a protected area, you should get planning permission from the local council before work commencement. Also, find the building regulations to know what you need for the project.
  • Carefully think of the best use for the garage. It is one thing to want to convert a garage, but an entirely different thing to know the most suitable use for it. The use of the room will determine the direction of the conversion project; it may be too late to change your mind if work commences.
  • Thoroughly inspect the current structure, although this part may be for the contractors. However, the state of the structure will reflect the overall cost of the conversion. If the structure needs to be improved to handle the modifications, it costs money. If it is already sound, there is no further need for adjustments.
  • Find a suitable contractor or garage conversion specialist. There are several marketplaces to use, and is one of them. You will find several traders for easy comparison and selection. Always use trusted platforms and verified services instead of relying on ads alone.
  • Ensure you document every discussion between you and the contractor you select. Word of mouth is not enough, especially for a project of this magnitude. It helps in comparing quotes, designs, and other aspects of the project. With the document, you can easily calculate the overall cost and make appropriate plans.
  • Make room for extra costs that are not a part of the main quotes from the contractor. If you are going to plaster and paint, have a budget because some contractors may not include it in their quotes. Do not go overboard on this part of the project to avoid overshooting your budget.
  • Locate stores offering sales on specific items you may need to finish the project. They may not be the main part of the fixtures, but they make the entire project look excellent. However, this expense does not have to eat deep into your budget if you can find the items on sale or with discounts.

FAQs Regarding Garage Conversion 

  1. Is Getting Approval for Building Regulation Necessary for Garage Conversion?

Getting approval for building regulations is crucial for a garage conversion. Any modifications to buildings or properties must pass through the approval stage and abide by the regulations governing such modifications. The same rule applies to all property types, whether or not it is a private residence.

  1. Is Planning Permission Necessary for Garage Conversion?

You may not need planning permission before converting your garage and putting it to another use. Since many garages are integrated into the main building, they are already within the appropriate permitted development scope.

However, a standalone garage may require a planning permit, especially if the property is in a conservation area or is listed. The best step is to contact the appropriate authorities to determine whether or not you need permission to make any changes to the structure. Note that new houses must maintain their garages as places to park cars and cannot convert them for any other use.

  1. Should I Get Insurance Cover for Garage Conversion?

If you do not have insurance for your home, it is best to get a policy that ensures your home is protected. It ensures you do not directly bear the cost of any structural damage during the project.

However, if you already have insurance overage for your home, inform your insurance carrier to avoid voiding the coverage. If there is any damage to the property during a garage conversion without pre-informing your insurance company, you may invalidate the policy.

Furthermore, you must find out what areas the insurance covers. Some policies do not offer coverage to outlying buildings such as garages. You may be removing the garage from under insurance coverage if you opt for a detached option. Nevertheless, you may take out a separate policy to cover the garage and other detached buildings.

  1. Does a Garage Conversion Increase a Property’s Value?

A garage conversion may significantly increase the value of a property, but it depends on its usefulness to the owner. An extra bedroom may make the property more useful for any owner, while an extra kitchen makes all the difference.

Utility rooms also add value as every homeowner finds a use for such spaces. What works for you may not be useful to a future owner. If you convert the space to a home office because you work from home, the next owner may not be thrilled by it.

  1. Is It More Affordable to Convert a Garage than to Get an Extension?

Typically, it is more affordable to convert a garage to a useful space than to add an extension. However, there is no hard and fast rule; the purpose of the conversion makes all the difference. If the conversion is to get an extra kitchen or guest bedroom, it will require plumbing, gas pipes, and light fixtures. These tend to be expensive, which significantly increases the conversion costs. However, if you are turning it into a personal space without necessarily living out of it, it may require only minimal changes. These may not cost so much and affects the overall conversion cost. The building’s structural condition also affects the cost. It significantly increases if there is a need for structural adjustments or repairs. These are some crucial aspects to consider before correctly determining whether a garage conversion is more affordable than an extension.
