The ultimate guide to adding value to a home by improvement

Home improvements can significantly impact the value of a property, making it more appealing to potential buyers and increasing its market price. In the UK, factors such as location, buyer demand, and the overall property market influence the return on investment (ROI) for home improvements. However, certain renovations consistently add value. This article explores various home improvements, their potential value-added, and considerations for homeowners looking to invest in their property.

1. Kitchen Renovations: The Heart of the Home

Why It Adds Value

The kitchen is one of the most important areas for potential buyers. A modern, well-designed kitchen can add between 5% and 15% to a home’s value. Buyers look for stylish yet functional layouts with high-quality appliances and ample storage.

Best Improvements

Upgrading worktops (e.g., quartz or granite)

Replacing outdated cabinets with modern units

Installing energy-efficient appliances

Adding a kitchen island for extra workspace and seating

Enhancing lighting with under-cabinet LED strips and pendant lights

ROI Estimate: 50%–80% of the renovation cost

A full kitchen remodel can cost between £5,000 and £25,000, depending on size and quality. However, even minor updates, such as new cabinet doors or fresh paint, can refresh the space and make a noticeable impact.

2. Bathroom Upgrades: Modern and Luxurious Appeal

Why It Adds Value

Bathrooms are another critical selling point. An outdated or poorly maintained bathroom can be a deal-breaker for buyers. Upgrading a bathroom can add 4%–10% to a home’s value.

Best Improvements

Installing a new suite with a modern bath, shower, and sink

Adding a second bathroom or en-suite (especially in older homes)

Updating tiles and flooring for a contemporary look

Installing underfloor heating for a touch of luxury

Improving water efficiency with low-flush toilets and aerated taps

ROI Estimate: 50%–70% of the renovation cost

A full bathroom remodel can cost between £3,000 and £10,000, but even simple updates like new taps, mirrors, and regrouting can make a big difference.

3. Loft Conversion: Adding Usable Living Space

Why It Adds Value

Converting a loft is one of the best ways to add value to a home, with a potential increase of 10%–20% in property value. It transforms unused space into a functional area, often used as a bedroom, home office, or playroom.

Best Improvements

Adding a dormer window for increased headroom

Installing proper insulation to improve energy efficiency

Including an en-suite bathroom for maximum appeal

Ensuring adequate lighting with skylights or Velux windows

ROI Estimate: 50%–75% of the renovation cost

A typical loft conversion costs £20,000–£50,000, but it can increase a home’s square footage, making it a great long-term investment.

4. Extension: Expanding the Living Area

Why It Adds Value

Extensions provide additional space, making homes more suitable for growing families or those needing extra room for work or leisure. A well-designed extension can add 10%–25% to a property’s value.

Best Improvements

Single-storey rear extension (popular for kitchen-diners)

Side return extension (common in Victorian terraces)

Two-storey extension (adds bedrooms and bathrooms)

Garden room or office (ideal for home working)

ROI Estimate: 40%–60% of the renovation cost

Costs range from £30,000 to £100,000+, depending on size and materials. Planning permission may be required for larger projects.

5. Energy Efficiency Improvements: Lower Bills, Higher Appeal

Why It Adds Value

With rising energy costs and government incentives, energy-efficient homes are increasingly attractive to buyers. Improvements in this area can add up to 14% to a home’s value and make it more appealing to eco-conscious buyers.

Best Improvements

Upgrading to double or triple glazing

Adding loft and wall insulation

Installing a new boiler or heat pump

Fitting solar panels (may qualify for government incentives)

Using smart home technology for energy monitoring

ROI Estimate: 50%–80% of the renovation cost

Costs vary widely, from a £1,500 boiler upgrade to a £5,000+ solar panel installation.

6. Garden and Outdoor Improvements: Maximising Curb Appeal

Why It Adds Value

Outdoor space is a major selling point, especially post-pandemic when homebuyers value gardens more than ever. A well-maintained garden can add 5%–10% to property value.

Best Improvements

Landscaping with low-maintenance plants

Adding decking or a patio for outdoor entertaining

Installing garden lighting for ambiance

Creating an outdoor office or summerhouse

ROI Estimate: 40%–60% of the renovation cost

Spending £5,000–£15,000 on landscaping and outdoor structures can provide a strong return.

7. Kerb Appeal Enhancements: First Impressions Matter

Why It Adds Value

Buyers often decide within seconds whether they like a home. Improving the exterior can boost a home’s desirability and add 5%–8% to its value.

Best Improvements

Repainting the front door and exterior walls

Replacing old windows and doors

Upgrading the driveway with resin or block paving

Installing exterior lighting for security and style

ROI Estimate: 50%–70% of the renovation cost

Simple updates like repainting and new fixtures cost as little as £500–£5,000 but can dramatically improve perception.

8. Open-Plan Living: Modern and Spacious Appeal

Why It Adds Value

Modern buyers favour open-plan layouts, particularly in the kitchen and living areas. Removing walls to create a more open space can increase a home’s value by 3%–7%.

Best Improvements

Knocking down walls to merge kitchen and dining areas

Adding sliding or bi-fold doors to connect to the garden

Ensuring adequate structural support with beams where needed

ROI Estimate: 50%–80% of the renovation cost

Costs range from £2,000–£10,000, depending on structural work required.

Final Thoughts: Which Renovations Are Best?

The best home improvements depend on budget, property type, and buyer demand. Loft conversions and extensions offer the highest value increase but require substantial investment. Kitchen and bathroom upgrades are essential for modern appeal. Energy efficiency is an increasingly important factor, especially with government incentives.

For those selling soon, cost-effective updates like repainting, improving kerb appeal, and minor bathroom/kitchen refreshes offer the best ROI with minimal disruption.

Before undertaking any major work, always check planning permission rules and consult estate agents to gauge local demand.
