For an accurate quote, consult local contractors who can provide personalised estimates based on your renovation needs. The numbers provided are rough averages and may vary depending on location and project requirements. Starting with a comprehensive list of the tasks you wish to undertake is a wise initial step in calculating renovation costs and planning your budget effectively.

Factors Affecting Cost

Here are the main things that will affect how much your renovation costs:

Cost by Size

The home renovation project's cost depends on the house's size. A larger house requires more materials and labour to complete the project. To estimate the renovation cost, it's important to consider the total square footage of the house and the number and size of the rooms since these factors significantly impact the cost.

Additionally, the spatial aspect should not be overlooked. Allocating sufficient room for construction workers or contractors to manoeuvre within the workspace can prevent unnecessary delays and expenses arising from a congested environment. This factor can also influence material requirements; larger rooms typically consume more materials than their more compact counterparts.

Furthermore, rooms with elevated ceilings introduce their own set of considerations. They may necessitate additional labour and specialised equipment, such as lifts for accessing hard-to-reach areas or specific tools designed for working on high ceilings and fixtures mounted well above wall height.

Estimating home renovation costs based solely on square footage may not provide the most accurate picture, as the expenses can vary significantly from one room to another. Renovation costs typically span a wide spectrum, ranging from £15 to £118 per square foot.

A budget-friendly renovation (£15-£47 per square foot) predominantly focuses on preserving your home's structural integrity, which includes the roof and walls. In such projects, synthetic materials like laminate and vinyl and ready-made units for cabinetry and shower stalls are often utilised.

A mid-range renovation (£47-£79 per square foot) encompasses upgrades to home appliances and systems, offering a notable improvement in quality and functionality.

A high-end renovation (£79-£118 per square foot) is characterised by structural modifications and the integration of luxury appliances and premium materials like hardwood or natural stone. This category may involve a complete overhaul of an older home.

Cost by Renovation Types

The specific remodelling project(s) you choose significantly influences the overall cost of your renovation endeavour. Different projects come with varying price tags, reflecting the complexity, materials, and labour involved. Here's a breakdown of estimated costs for various types of remodelling projects:

  • Basement: £9,480 - £23,700
  • Bathroom: £15,840 - £30,220
  • Bedroom: £7,920 - £11,850
  • Deck addition: £11,850 - £15,840
  • Garage: £5,530 - £11,850
  • House exterior: £3,950 - £11,850
  • Kitchen: £18,170 - £104,400
  • Living room: £7,920 - £11,850
  • Roof replacement: £6,715 - £11,347
  • Room addition: £106,650 - £222,780

Labor Cost

Labour costs are a significant portion of professional home remodelling expenses, accounting for approximately half of the total project cost. The specific contractors required for your project depend on its scope and complexity, and the pricing structure can vary, either by the project or on an hourly basis. Additionally, trades that necessitate licensing in your state often come with higher costs. If you choose to hire a general contractor to oversee the project, this typically adds 10% to 20% to the overall cost.

  • Architect: £99 - £198
  • Carpenter: £27 - £70
  • Electrician: £31 - £95
  • Flooring: £31 - £79
  • HVAC (Heating, Ventilation, and Air Conditioning): £59 - £118
  • Painter: £16 - £40
  • Plumber: £59 - £102
  • Roofer: £36 - £59

Cost by Location

The location of your renovation project can significantly impact the overall costs, with densely populated urban areas typically carrying higher price tags. Conversely, very rural areas might also incur higher expenses due to factors such as contractor travel and the transportation of materials over longer distances.

Additional Cost Considerations

The following are several additional factors that can influence the cost of your home renovation.

Age of Home

Renovating older properties can present challenges and expenses not found in newer homes. These factors can contribute to higher renovation costs:

Structural Repairs

Older homes may require more extensive structural repairs due to wear and tear. Addressing issues with the foundation, roofing, and load-bearing walls can increase the overall cost.

Retrofitting for Modern Amenities

Retrofitting older homes to accommodate modern amenities, such as updated electrical systems, plumbing, and HVAC, can be a significant expense. To comply with present-day building codes and safety regulations.

Asbestos Removal 

Asbestos is commonly used in building materials in older homes, and its removal or encapsulation can be costly. The health of both occupants and workers needs to handle and remove asbestos safely.

Preservation of Historic Features

If your home is a historic building, preserving or recreating its original appearance can involve specialised work and materials, which can be more expensive than standard renovation.

Unforeseen Issues

Renovating older homes can uncover unforeseen issues like hidden structural damage or outdated wiring that needs replacement, adding to the project's scope and cost.

Changing Wall Structure

If you're thinking about changing the layout of your home, it's important to plan carefully and get professional help. This is especially true if you want to remove walls that support the weight of your house. To make sure everything is safe and secure, you should hire a structural engineer to oversee the project. Here's what you can expect in terms of costs:

Structural Engineer Consultation

Hiring a structural engineer for a consultation typically costs between £240 and £560. This investment is essential to assess the feasibility of your project, ensure it complies with safety regulations, and provide guidance on the necessary structural modifications.

Removing Load-Bearing Walls

Removing load-bearing walls is a complex and costly endeavour due to the need for structural reinforcement. This process can require significant alterations to support the load previously carried by the wall. Costs for removing a load-bearing wall can range from £850 to £7,900 or more, depending on factors such as the wall's size, location, and the extent of structural modifications required. It could sometimes even exceed £7,900, especially if it involves major structural changes.


Obtaining the necessary permits is a crucial step in any home renovation project, especially if it involves structural changes, additions, or significant plumbing and electrical work. Here's what you should know about permits and their associated costs:

Permit Requirements

When undertaking a comprehensive whole-home renovation or making substantial alterations to your property, you will likely need one or more building permits. These permits are essential to ensure your project complies with local building codes and safety regulations.

Types of Permits

The specific permits required can vary based on the scope of your project. Common permits include those for structural changes, additions, plumbing, electrical, and HVAC installations.

Preparing for a Renovation

Preparing for a large renovation project involves several important steps to ensure a smooth and successful renovation. Here are some key aspects of preparation and associated costs:

Landscaping and Site Preparation

In some cases, you may need to clear your landscaping to create access for construction trucks and equipment. This can involve removing trees, shrubs, or other features. The cost of landscaping and site preparation can range from a few hundred to a few thousand dollars, depending on the extent of the work required.

Furniture Storage

To protect your furniture and belongings during the renovation, you may put them in storage. The cost of furniture storage can vary depending on the size and duration of storage.

Interior Design Consultation

Consulting with an interior design professional can help you plan the finished look of your home and make informed design decisions. The total cost will depend on the scope of the consultation and design services you require.

Temporary Accommodation

If your home is undergoing extensive renovations that make it temporarily uninhabitable, you may need to budget for temporary accommodation. Costs for short-term rentals or hotel stays can vary significantly based on location and duration.


It's always prudent to allocate a budget for potential repairs, even when your home seems to be in good condition. You can't always anticipate the extent of necessary repairs until contractors begin delving into your walls, floors, or roof. Planning for potential budget overages in advance is a smart strategy to avoid unpleasant surprises midway through your renovation journey. Let's take a look at some significant structural repairs and their average costs:

  • Foundation repair: £1,580 to £5,925
  • HVAC repair: £1,580 to £2,370
  • Rewiring: £4.75 to £7.90 per square foot
  • Roof repair: £237 to £11,850
  • Roof replacement: £6,715 to £11,347
  • Sewer line replacement: £2,370 to £4,740
  • Water heater replacement: £672.50 to £2,765

These figures represent average costs and can vary depending on factors such as the extent of the repairs needed and your location. Including a buffer in your budget for unexpected repairs is a wise financial strategy when embarking on a renovation project to ensure you're well-prepared 

for any surprises that may arise.

Signs That You Need to Renovate

Many homeowners can find the idea of renovations daunting in terms of cost and stress. However, regardless of your initial investment in your home, it's important to recognise that renovations may become necessary over time. While they often come with a price tag, certain signs can indicate when it's time to consider a renovation:

Time for a Home Revival

If you find your beloved home grappling with the relentless wear and tear of time, it might be a telltale sign that a renovation is in the cards. Renovating your home can give it a new lease on life, from peeling wallpaper to crumbling ceilings.

When the need for renovation goes beyond the cosmetic and delves into structural territory, seeking professional counsel from a skilled builder is a prudent step. Their expertise can illuminate the extent of the structural improvements required and provide you with a clear understanding of the financial commitment involved.

Remember to create a comprehensive budget, including a safety net of at least 10% for those unexpected twists and turns that renovation journeys tend to unveil. 

Leaky Roof

When your roof starts to leak, it's a clear signal that action is needed, and the sooner, the better. While roofs typically have a lifespan of around 30 years, the presence of a leak demands immediate attention from a reputable roof repair service.

As a responsible homeowner, being extra vigilant regarding leaky roofs is essential. It's not just about the unsightly stains on your ceiling; it's about the potential health hazards that may be lurking beneath the surface. A professional roof inspection is the best course of action. You need someone who can comprehensively evaluate the roof's condition and a clear roadmap for necessary repairs or replacements. This is where a skilled expert comes in. Hire a professional to ensure your home's integrity and the well-being of its occupants. Don't delay in taking prompt action regarding a leaking roof - it's the superhuman thing to do!

A Call for Transformation

The statistics don't lie; we tend to dwell in the same abode for an average of twenty-one years. It's only natural for our tastes and preferences to evolve during this extended period. That interior design scheme you once adored upon moving in might not quite resonate with your current sensibilities.

So, when your style transforms, it's only fitting that your home undergoes one. Our homes are special in our hearts as they reflect who we are. We invest a substantial portion of our lives within their walls, and they must exude our personality and taste. It's not just for our sake but also to offer visitors a glimpse into our identity.

While some aspects of a renovation may necessitate professional expertise (unless you're a bathroom renovation specialist), selecting the right renovators is paramount, especially if your goal is to align your home with your evolving style. One misstep in this process, and you might end up with a home that doesn't quite capture the essence of your style – defeating the very purpose of renovating.

Opting for specialised renovation companies can give you greater control over your home's aesthetics. For instance, a dedicated kitchen renovation company is often better equipped to bring your vision to life than a general home renovator.

Regardless of your choice, the linchpin is clear communication. Ensuring that your vision is heard and accurately interpreted is key. Sometimes, being a tad persistent is worthwhile if you'll ultimately have the home you've always envisioned.

You Need More Space

When a growing family fills your home's once-roomy halls, the walls can start closing in. Children's laughter and the pitter-patter of tiny feet bring joy, but they also bring the need for more room to breathe.

There's good news if your family is growing and you need more space. A redesign of your home and some thoughtful extensions can make a big difference. You'll have more living space, comfortable bedrooms, and a well-equipped kitchen that meets your changing needs. When the project is finished, you'll feel the difference right away.

The result is not just a more spacious abode but a haven that accommodates the vitality of family life. So, when your family's growth beckons for more space, a tailored renovation and extension can be the key to unlocking a brighter, more accommodating future in the very place you call home.

You Can Afford It

Facing the financial aspect of renovation may not be the most exhilarating step, but it's undeniably one of the most critical. Renovations can often appear as voracious consumers of funds, and it's imperative to ensure that your financial footing remains steady throughout the process.

A comfortable budget is not just about starting the renovation but sustaining it. Unforeseen expenses can loom like spectres, and you don't want to sacrifice winter heating to cover them. A comprehensive financial plan should encompass these uncertainties, ensuring you're not caught off guard.

Halting a renovation midway due to financial constraints can result in a home feeling disjointed and lacking cohesion. It's akin to leaving your masterpiece incomplete. So, before you embark on this transformative journey, scrutinise your financial resources and ensure you can comfortably see it through to fruition. Your home's cohesion, functionality, and peace of mind depend on it.

Professional vs. DIY

The idea of cutting costs by taking the DIY route can be alluring for homeowners contemplating a home renovation. It's a commendable approach for smaller projects that align with the skills of experienced do-it-yourselfers (DIYers). However, the wisdom of calling in the professionals shines through regarding more extensive renovation undertakings.

Professional Renovation

When it comes to messing with your home's bones, trust the experts! Structural changes need professional contractors. They're like the superhero protectors of your home's integrity and local building codes.

And hey, don't forget the licensed electricians and plumbers. They're the sidekicks needed for any wiring or plumbing changes. These folks have undergone intense training and have tons of experience under their utility belts.

The cool thing about the pros is they work faster and more effectively than trying to DIY. Furthermore, their established relationships with wholesalers enable them to acquire materials at reduced rates, providing you with cost savings.

Sticking to those building codes isn't just a rule; it's your home's value insurance. And most pros even offer guarantees on their work, so you can sleep easy knowing your home's in good hands.

DIY Renovation

If you've got time and patience, small renovation projects might be your chance to shine. You can do DIY tasks like changing faucets, painting walls, or installing kitchen fixtures.

However, it's often wiser to call in the professionals regarding the big game. A recent NBC News survey revealed that 55% of DIY enthusiasts were disappointed with how their big projects turned out. Even worse, the same percentage found that these endeavours dragged on much longer than anticipated.

It's all about being real with yourself. Recognise your limits, both in terms of time and skills. While DIY can be immensely satisfying for smaller changes, larger transformations are often best entrusted to those who make it their profession. So, before you dive into a project, weigh the scope and complexity and consider whether it's a job for the pros or your inner DIY guru.

How To Save on Home Renovation

Home renovation costs have a knack for spiralling out of control, whether your budget is big or small. To keep your project on track and in harmony with your financial goals, consider these handy tips:

Create and Stick To a Budget

Budgeting isn't about being tightfisted; it's about being smart with your resources, whether your project is grand or petite. Here's a down-to-earth guide to managing your finances when sprucing up your home:

Know Your Financial Limits

Your budget isn't about cutting corners; it's about knowing your financial boundaries. Before you open your wallet, understand how much you can comfortably set aside for your project, whether it's a significant amount or more modest funds.

Break It Down

If you're diving into a home project, begin by determining the dollar amount you're ready to invest. Then, get into the specifics. Calculate the costs of materials, fixtures, and labour, and don't forget those sneaky taxes.

Spreadsheet Smarts

Create a simple list of everything you'll need. Collect quotes for both labour and materials, including those taxing taxes. This sheet will shine a light on where your budget is gobbled up. You can make savvy decisions from there, like choosing more budget-friendly materials or nixing unnecessary extras.

Prepare for the Unexpected

Budget for surprises because they tend to sneak in. Some experts recommend squirting around 10% of your budget for these unforeseen hiccups, but the exact amount is up to you.

Pay Cash

When planning to fund your home renovation, you have two main options: using your own cash or taking out a loan. Let's break it down in plain terms.

Cash Is Great

Paying with your own money (cash) is smart because you won't have to deal with loan interest or credit card charges. This is especially handy if your renovation isn't about selling your home. To make it happen, start saving up by tightening your household budget.

Loan Logic

On the flip side, consider getting a loan if your renovation aims to boost your home's resale value. Why? Because the improvements you make can increase your home's worth, and you'll likely make enough money when you sell to repay the loan quickly. It's a clever move if you're in it for the long-term gain.

So, it depends on your situation and goals. Cash saves you from extra financial costs, while loans can be a strategic choice for renovations that'll pay off when you sell. It's all about finding the right fit for you.

Take Your Time

Timing is everything when it comes to home renovation. Rushing into decisions can leave you with regrets down the line. Here's why taking your time matters:

Crafting a cohesive and functional design takes careful consideration. If you're feeling overwhelmed, remember that taking your time is okay, even if you've got the money ready. Rushed choices can lead to disappointment.

Start with the most intensive parts of your project, such as one or two rooms, and complete them before moving on to others. This approach can save you from unexpected expenses. If surprises do pop up, you'll have the resources to handle them without taking loans or making big sacrifices in other areas.

Do It Yourself

Getting your space ready before the renovation crew arrives can greatly affect your project's overall cost. Here's how to be proactive and keep those labour costs down:

Cleaning, preparing surfaces, and even painting can save you precious hours of labour costs. Since you typically pay per hour, doing some of these tasks can set you ahead.

You can achieve remarkable results with a moderate level of DIY skills, a willingness to learn, and the power of YouTube. Renting tools can be a great motivator, with due dates pushing you to complete tasks efficiently.

While you can tackle many tasks, some require a professional's touch and may even demand a license. It's essential to know when to bring in the experts. For those tasks you can handle, ensure you obtain the necessary permits to adhere to regulations and ensure the safety and future comfort of your home's inhabitants.

Balance High and Low-End Materials

When it comes to renovation spending, it's all about finding the right balance. Here's a strategy to help you get the most value from your budget:

Think of your renovation budget like a puzzle. Spend less in some areas, but allocate more to those statement items that will really make your home shine. It's all about getting the most bang for your buck.

The perfect balance can vary from person to person and project to project. You might choose to invest more in stunning windows that completely transform the appearance of your home while taking it slow on some appliances.

Don’t Skimp On Cost-Saving Opportunities

When buying items for your renovation, how you pay can make a significant difference. Here's why it's often better to avoid credit:

If you use credit to purchase items, the interest on your payments can quickly eat away at any money you might save from using energy-efficient appliances or other cost-effective choices.

Paying with cash can provide a clearer return on investment. By avoiding interest charges, you'll enjoy the full benefits of your energy-saving purchases sooner.


Home renovations can vary in size and cost. Some small cosmetic jobs can be DIY projects, but if you're changing your home's structure, hire pros. Budget carefully and prepare for surprises by keeping some extra funds handy.
