Define your goals
What rooms, what changes, what outcome?
Set a budget + 15–20% contingency
Unexpected costs are the norm, not the exception
Check planning permission requirements

Create a timeline
Allow 2–4 weeks for quotes, plus lead times for materials and tradespeople

6. Common Renovation Mistakes to Avoid
Learn from others — these are the mistakes that cost UK homeowners the most time and money.
Underestimating the budget
Always add 15–20% contingency. Hidden problems are common in older properties.
Skipping the survey
A building survey can reveal structural issues, damp and asbestos before you commit.
Hiring on price alone
The cheapest quote is rarely the best value. Check reviews and credentials.
Changing the plan mid-project
Scope changes are the #1 cause of budget overruns. Finalise decisions before work starts.
Not getting Building Regs sign-off
Unsigned work can cause problems when selling. Always get completion certificates.
Paying too much upfront
A 10–20% deposit is reasonable. Never pay in full before completion.
