Hidden Costs Homeowners Often Overlook
When budgeting for a renovation in Crawley, it’s important to allow for unexpected or secondary costs, such as:
-
- Electrical rewiring or consumer unit upgrades
-
- Plumbing repairs or pipe replacements
-
- Asbestos removal in older properties
-
- Structural reinforcement or steelwork
-
- Building control fees and inspections
-
- Waste removal and skip hire
A sensible contingency of 10–15% is recommended for most renovation projects.
Do You Need Planning Permission?
Not all renovations require planning permission, but some do — particularly home extensions, loft conversions and structural changes.
You may need permission if:
-
- You’re extending beyond permitted development limits
-
- The property is in a conservation area
-
- The renovation significantly alters the exterior
A professional local builder can advise whether planning approval or building regulations apply to your project.
How to Budget Smartly for a Renovation
To keep your renovation on track and within budget:
-
- Get detailed, itemised quotes
-
- Prioritise essential work before cosmetic upgrades
-
- Choose durable materials over short-term savings
-
- Work with a builder who offers clear project management
-
- Avoid changing plans mid-build where possible
Planning properly at the start often saves thousands later.
