✅ 20 Renovation Mistakes to Avoid and How to Get It Right

These 20 common mistakes can derail your project, drain your budget, or reduce your property’s value. Whether you’re upgrading a buy to let or restoring a family home, this checklist helps you stay ahead.

 

1. Skipping Planning Permission or Building Control

Many works require approval from your local authority. Ignoring this can lead to fines or forced demolition.

Tip: Check on the Planning Portal or consult your local planning officer.

 

2. Underestimating the Budget

Hidden issues like damp, wiring, or structural damage can blow your budget fast.

Tip: I always add a 20 percent contingency to all estimates.

 

3. Choosing the Wrong Contractors

Unqualified or unvetted tradespeople can leave behind poor workmanship and legal problems.

Tip: Always check references, insurance, and written contracts.

 

4. Ignoring Structural Issues

Covering cracks with paint won’t fix the foundation.

Tip: Get a full structural survey before planning any cosmetic work.

 

5. Over Renovating for the Area

Adding luxury finishes to a modest house often leads to overspending with no return, particularly when you pay full price for items. See my document on how to install kitchens and bathrooms at up to 90% off here at:

Best-Value-Kitchens

Tip: Match your upgrade level to the best homes in your area, but do not exceed it.

 

6. Poor Project Management

Without structure, your site becomes chaotic. Overlapping trades waste time and money.

Tip: Use a clear schedule of works and assign one person to coordinate everything.

 

7. Neglecting Energy Efficiency

Poor EPC ratings can block rentals and future sales.

Tip: Insulate, upgrade heating, and install energy efficient lighting and windows.

 

8. Disturbing Asbestos

Often found in homes built before 2000, asbestos is hazardous, can be lethal and is legally regulated.ALways remember Artex into the 1990s can contain asbestos. See my guide here at: https://solidyields.com/artex

Tip: Always arrange a pre refurbishment asbestos survey before demolition.

 

9. Changing the Plan Midway

Making design changes during work leads to delays, waste, and extra cost.

Tip: It is critical to finalise all layouts and finishes before work begins. I have usually got my final plan ready before I even take possession of the property so I can hit the ground running at day one.

 

10. Overlooking Insurance and Legalities

If you don’t tell your insurer about structural works, your policy may be void.

Tip: Notify your insurance provider and mortgage lender before renovation begins.

 

11. Overlooking Invasive Plants Like Japanese Knotweed

Knotweed and other invasive species can reduce property value and block mortgages.

Tip: Inspect gardens and neighbouring land. Use a professional treatment service with a 10 year guarantee.

12. Skipping a Proper Schedule of Works

Without a proper work timeline, jobs overlap, trades clash, and delays mount.

Tip: Map out all tasks in order, from roof to ground, and get agreement from your builder or team.

 

13. Poor Lighting Design

Insufficient lighting makes even new rooms feel gloomy.

Tip: Use a mix of ceiling, task, and accent lighting. Add enough sockets and switches.

 

14. Ignoring Ventilation

Modern insulation traps moisture, causing condensation and mould.

Tip: Install extractor fans in bathrooms and kitchens and add window vents.

 

15. Failing to Check Plumbing and Drainage

Hidden leaks and poor connections lead to expensive repairs after completion.

Tip: Test all systems before walls or floors are sealed.

 

16. Not Checking the Roof Early

A leaking roof can undo all your internal work.

Tip: Inspect and fix roof tiles, flashing, and gutters before interior finishes.

 

17. Buying Materials Too Early or Too Late

Storing materials on site risks damage and theft, but late deliveries cause project delays.

Tip: Schedule deliveries in line with the timeline. Use trusted suppliers.

 

18. Not Thinking About Future Maintenance

Designer taps and obscure parts may be hard to replace later. Use plastic water pipes as far as possible and I do not use copper any more as far as possible to reduce theft. Fit boilers as late as possible in the project,

Tip: Choose reliable, easy to maintain fixtures and finishes.

 

19. Overlooking Fire Safety

Especially in HMOs and flat conversions, fire safety is not optional.

Tip: Fit fire doors, smoke alarms, and escape routes as required by building regulations.

 

20. Not Planning for Waste Disposal

Waste builds up fast. Skips fill quickly and local authorities have rules. Check for asbestos and allow for specialist removal if it is in the building.

Tip: Arrange skips and permits early and plan for recycling or clearance services
