Best ways to add value to your home in Devon

What returns the most in 2026

Devon estate agents we work with consistently rank these as the best-value upgrades:

1. Loft conversion with en-suite — typically adds 15–20% to property value
2. Single-storey kitchen extension — 10–15% uplift on a 3-bed semi
3. Garage conversion to home office or annexe — 5–10%
4. Garden room with proper foundations — adds usable square footage at lower cost
5. Re-roofing with insulation upgrade — strong EPC gains

What to avoid

• Over-personalised finishes
• Swimming pools (negative return in most of Devon)
• Removing all bedrooms for one giant master
• Cheap conservatories

EPC matters more every year

With MEES tightening, an EPC jump from D to C can be the difference between a fast sale and a 6-month sit. Insulation, triple-glazing on extensions, and a heat pump-ready hot water system all help.
