When
Planning a Residential Renovation
• • •
Planning a residential renovation is an exciting milestone. Whether you’re restoring a Victorian terrace to its former glory, extending a growing family home, or reconfiguring a dated layout to suit modern living, the possibilities can feel inspiring and full of promise. A well-executed renovation not only enhances your day-to-day comfort but can also add significant long-term value to your property.
However, beneath the surface of glossy design ideas and Pinterest boards lies a process that requires careful preparation, realistic budgeting and informed decision-making. Renovations are complex undertakings involving multiple trades, regulations, timelines and financial commitments. Without the right groundwork, even relatively straightforward projects can spiral into unexpected costs, delays and unnecessary stress.
KEEP YOUR PROJECT ON TRACK BY AVOIDING THESE
Failing to Set a Realistic Budget
One of the most common mistakes is underestimating costs. It’s not just the obvious expenses such as materials and labour; you’ll also need to factor in:
- Professional fees (architects, surveyors, structural engineers)
- Planning application costs
- Building Control fees
- Temporary accommodation (if required)
- Contingency funds
As a rule of thumb, set aside at least 10–20% of your total budget for unexpected costs. Older properties, in particular, can reveal hidden issues such as damp, outdated wiring or structural concerns once work begins.
Skipping Proper Planning and Design
Rushing into building work without a clear, detailed plan can lead to confusion, delays and costly changes mid-project. Investing time in the design phase will save you money and stress later.
Ensure you have:
- Detailed architectural drawings
- A clear scope of works
- A written specification
- Agreed finishes and materials
The more decisions you make upfront, the smoother the construction phase will be.
Ignoring Planning Permission and Building Regulations
In the UK, many types of renovation work require either planning permission or compliance with Building Regulations — or both.
Even if your project falls under permitted development rights, you must still comply with Building Regulations. Failing to obtain the necessary approvals can result in fines, delays, or problems when selling your property in the future.
Always check with your local planning authority before starting work.
Choosing the Wrong Contractor
Selecting a builder based solely on the lowest quote can be a costly mistake. While price is important, it shouldn’t be the only deciding factor.
Before appointing a contractor:
- Check references and past projects
- Confirm they have appropriate insurance
- Ensure they are experienced in similar types of renovation
- Request a detailed written quotation
A reputable builder will be transparent about costs and timelines and will communicate clearly throughout the project.
