 Trustindex verifies that the original source of the review is Google. I had a very smooth and accommodating experience. Penny Brown came around when I was expecting the visit, was very mindful that I was on work calls, and was particularly accommodating that there was a heavy piece of furniture that I couldn’t move and so worked around it. Really stress free and so lovely to have a nice customer service experience as it just starts the day off a little better :)

Why Proactive PPM is the Foundation of Effective Building Maintenance

Reactive maintenance (fixing things only when they break) is costly, inefficient, and disruptive. Our proactive building maintenance strategy, built on custom PPM programmes, transforms your asset management, providing predictable performance and clear benefits:

Predictable Spending: Convert unpredictable repair costs into manageable operational expenditure (OPEX) with fixed contract pricing for all building maintenance needs.
Regulatory Peace: Our scheduling ensures compliance with all mandatory regulations (Gas Safe, L8, F-Gas), providing documentation for audits.
Extended Lifespan: Regular servicing and calibration prevent wear and tear, dramatically increasing the operational life of expensive plant room equipment.
Operational Continuity: Proactive identification and fixing of minor faults prevents catastrophic system failures that halt business operations.
