Planned maintenance for developers and asset owners: protecting value and reducing risk

Published on: December 8, 2025

Buildings are long-term assets. Without structured maintenance, even high-quality developments can suffer from early component failure, higher energy use and complaints from residents or tenants. 

GSIM’s maintenance services are designed specifically for companies and developers, delivering both planned and reactive solutions that keep buildings safe, efficient and compliant. 

Who our maintenance services are for 

Our maintenance programmes are tailored to: 

Developers handing over new schemes but retaining long-term interests 

Asset owners and funds managing residential or mixed-use portfolios 

Housing associations and institutional landlords 

Property and facilities management companies 

Why regular maintenance saves money 

Compared with sporadic, reactive repairs, planned maintenance offers major cost savings: 

  • Preventive maintenance – scheduled inspections identify issues early, before they become expensive failures. 
  • Extended equipment lifespan – well-maintained systems suffer less wear and last longer, reducing capital replacement costs. 
  • Reduced emergency call-outs – proactive work lowers the risk of unexpected breakdowns and disruptive outages. 
  • Better energy efficiency – tuned and cleaned plant consumes less energy and performs more reliably. 
  • Preserved property value – well-presented, well-maintained buildings attract and retain high-quality occupants. 
  • Compliance and safety – regular checks help meet statutory obligations and reduce the risk of enforcement action or claims. 
  • PPM and reactive maintenance working together 
  • An effective maintenance strategy blends: 
  • Planned Preventative Maintenance (PPM) – structured schedules for inspections, servicing, testing and statutory compliance. 
  • Reactive works and contracts – clear processes and response times when issues do occur, supported by robust work order management and root cause analysis. 

GSIM works with clients to design maintenance contracts, set service level agreements and manage both PPM and reactive works so that portfolios remain safe, efficient and resilient.
