HOW MUCH DOES IT COST TO RENOVATE? THE DEFINITIVE GUIDE TO PRICES, MATERIALS AND TIPS TO AVOID SURPRISES.

INTRODUCTION

Renovating a home or business premises is much more than just changing the flooring or painting the walls: it is an opportunity to improve your quality of life, increase the value of the property and create a space that suits your style and needs. However, one of the biggest questions before starting is always the same:
How much does a renovation really cost?

At Bybo Group, experts in construction, project management, design and interior design, we have been guiding clients through this process for years. And we know that the key to getting it right is not just knowing the price, but understanding what factors determine it, why it can vary so much and how to avoid cost overruns.

In this article, we tell you everything clearly, with real examples and practical recommendations that will save you worries during the work.

What really influences the price of a renovation

A renovation cannot be measured only ‘on the surface’. Every detail affects the price: square metres, materials, technical difficulty… and even the current condition of the property. That is why it is so important to have the project professionally assessed from the outset and to be wary of construction companies that give estimates on the fly with immediate delivery and verbal estimates.

Let’s break down the main factors so you can get a complete picture

Square metres: the basis of any renovation quote

The size of the space is one of the most straightforward elements when calculating a quote:

• More surface area = more materials
• More surface area = more labour
• More surface area = more time to complete the work

But something that many people don’t know is that the relationship is not always linear. For example:

• A small home may have a higher price per square metre because the logistics are more complicated (less space to work in, more cuts, more adjustments).
• In large homes, some jobs are optimised and the price can be better adjusted.

Approximate price per m²:

• Basic refurbishment or renovation/modernisation of the space: from €450/m²
• Average comprehensive renovation: €650–1,100 per square metre
• Renovation integral premium: +1.200 €/m²

At Bybo Group, we take precise measurements so that the quote is 100% tailored to your home and there are no unexpected variations later on. Por mucho que uno puede decir ” en una reforma nunca sabes que sorpresas te encuentras”. Puede ser cierto, pero tras los años de experiencia, ya sabemos que probabilidades hay en cada proyecto para poder avisar y prevenir a nuestros clientes de dónde podriamos encontrar dicha sorpresa.

Technical difficulty: a factor that makes all the difference

Some renovations are simple… and others require much more complex coordination.
This is where the team’s experience and proper planning come into play.

The interventions that usually increase the cost are:

• Layout changes (demolition of partitions, reinforcements, relocation of sockets and installations)
• Total renovation of electricity or plumbing
• Integration of home automation or advanced systems
• Renovations in old buildings (hidden damp, old installations, uneven floors)
• Special materials that require expert labour

A difficult renovation is not necessarily more expensive just because it is difficult, but because it involves more hours of skilled labour and greater precision to ensure a flawless result. It is also worth noting that with the right technical intervention from a competent team and the ability to anticipate problems and find solutions in good time, the number of hours of work can be reduced, as this eliminates the risk of having to repeat certain tasks.

At Bybo Group, we have specialised teams that ensure that each phase is carried out in accordance with professional standards and current regulations.

Materials: where the client has more control over the price

The choice of materials can cause a quote to vary by thousands of pounds.
Choosing well is key to maintaining the balance between aesthetics, durability and cost. Si un material es mas caro no significa que sea mucho mejor que el más económico, hay que ver en que es mejor y si es significativo para el resultado final o el uso definitivo.

The most important thing is that the materials are clearly specified in the quote, as terms such as ‘average quality’ or ‘standard range’ can mean very different things depending on the company.

✔️The most important factor in avoiding problems: a detailed quote

We want to be very clear on this point:
80% of problems in a renovation are due to insufficiently detailed quotations.

Un buen presupuesto debe incluir:

✓ Desglose por partidas
✓ Materiales especificados con marca y modelo
✓ Cantidades exactas (m², unidades, metros lineales)
✓ Mano de obra separada
✓ Tiempos estimados
✓ Condiciones de garantía
✓ Posibles extras previstos (si aplica)

A document like this avoids:

• Unexpected changes
• Lower quality materials
• Added costs
• Risks during the work

At Bybo Group, we work with transparent, comprehensive budgets that are reviewed with the client before starting the work. We know that trust is built from the beginning.

Conclusion: How much does a renovation cost? It depends… but it should always be clear

The final price depends mainly on three determining factors: square metres, technical difficulty and the materials used.
But what should not depend on these factors is your peace of mind. With a professional company, a team of qualified technicians to ensure proper supervision, or a project manager with the right qualifications (there are many professionals who claim to be ‘project managers’ but have never set foot on a construction site), a clear budget, and careful execution, a renovation can be a positive and transformative experience.
