Renovating your home is a significant investment, and understanding the costs involved can help you plan effectively. Whether you’re looking to modernise your kitchen, refurbish your bathroom, or undertake a full home renovation, knowing what to expect in 2025 is crucial.
At
Home Improvements & Construction Ltd (HICL Builders), we specialise in
home renovations, extensions, loft conversions, kitchen and bathroom refurbishments, and new builds in Surbiton and across South-West London. In this guide, we’ll break down the key factors affecting renovation costs and what you should budget for different types of home improvements.

Factors That Affect Home Renovation Costs
Several factors influence the cost of a home renovation, including:
1. Size and Scope of the Project
The larger and more complex the renovation, the higher the cost. A full house refurbishment will cost significantly more than a single-room renovation.
2. Property Condition
Older homes in Twickenham, Wimbledon, Woking and surrounding areas may require additional structural work, such as damp-proofing, rewiring, or plumbing upgrades, increasing costs.
3. Quality of Materials and Finishes
The choice of materials impacts your budget. Premium finishes like bespoke joinery, natural stone countertops, and designer fixtures will increase the price compared to standard materials.
4. Permits and Regulations
If your project requires planning permission or adherence to building regulations, this may add to the overall cost.
5. Labour and Professional Fees
Hiring experienced building renovation contractors in Surbiton, as well as the above mentioned areas ensures quality workmanship but can be more expensive than using less experienced tradespeople. However, if you want to avoid unexpected costs, stress and time, we highly recommend you research your desired contractor before beginning negotiations.
