About Commercial Improvements

A Trusted Name in Home & Property Improvement

We are a fully accredited installer of heating and insulation measures, proudly serving homeowners, landlords and local authorities across the UK for over 15 years.

Founded with a commitment to quality and customer satisfaction, Commercial Improvements Ltd has grown from a specialist insulation contractor into a comprehensive property improvement company. Today we deliver everything from cavity wall and loft insulation to full central heating systems, solar PV installations and air source heat pumps.

Our Values

What Drives Everything We Do

Our values aren't just words on a wall — they shape every survey we carry out, every installation we complete and every customer we serve.

Customer Satisfaction First
Your satisfaction is not an afterthought — it is the measure of everything we do. We won't consider a job done until you are completely happy with the result.
Respect & Integrity
We treat every home as if it were our own. Our engineers carry ID, arrive on time, work cleanly and always communicate clearly before, during and after the job.
Quality Without Compromise
We only promise what we can deliver, and we deliver exactly what we promise. Every installation meets or exceeds the relevant industry standard — no shortcuts, ever.
Health & Safety Always
The safety of our customers and our team is non-negotiable. All work follows current health & safety regulations and every engineer is fully trained and certified.
Transparent Communication
No jargon, no surprises. We provide clear, honest information at every stage — from your first enquiry through to final sign-off and aftercare.
Long-Term Reliability
We don't just install and disappear. Our 25-year guarantee and dedicated aftercare team mean we're still here for you years after the job is done.
