Explore how proactive facilities management reduces costs, prevents disruption and protects the long-term value of your commercial property.

Refurbishment costs vary significantly based on building size, scope of work, materials selected, and current condition. A minor render repair might cost £2,000, while a complete exterior transformation can reach £100,000 or more.

Detailed estimates from experienced contractors, after a thorough assessment, typically achieve 90-95% accuracy. Costs vary when hidden issues emerge (structural problems, asbestos, unexpected building regulation requirements), which is why a 10-15% contingency is essential.
Well-planned refurbishment typically achieves 15-30% annual ongoing ROI through rental increases. One-time benefits (avoided void periods, property value increases) can deliver 50-100%+ return in year one. Compliance-driven refurbishment may show lower direct ROI but protects existing income and maintains property value.
Payback periods vary widely: entrance and exterior improvements often pay back in 12-24 months. Compliance work may take 3-5 years. The key is ensuring payback occurs within your ownership timeline and that ongoing ROI justifies the investment.
Refurbish before marketing. Vacant buildings in poor condition sit empty longer and command lower rents. Refurbished properties let faster at higher rates. The extended void period from "waiting for tenant first" typically costs more than refurbishing while vacant.
Lease terms dictate this. Most leases don't allow landlords to increase rent mid-term for improvements. Refurbishment ROI on occupied buildings comes from higher lease renewals or improved tenant retention, avoiding void periods and re-letting costs.
Prioritise work with the highest ROI and defer lower-priority improvements. Phase work over 12-24 months. Focus on the exterior and entrance for maximum return; postpone internal improvements until the budget allows.
Research comparable market rents for similar buildings in better condition. Estate agents provide rental valuations showing achievable rents post-refurbishment. Conservative assumptions: 10-15% rent increase for an exterior refresh; 20-30% for a comprehensive refurbishment.
