Who We Work With
Sectors We Deliver Into
Insulation retrofit programmes for buyers who need framework-grade suitability, supervision and conformity records, not a homeowner-style brochure.
Housing Associations
Portfolio cavity, loft and IWI rollouts across social-housing stock, with resident comms, suitability documentation and completion records.
Facilities Management
Insulation works across managed estates, coordinated with planned maintenance windows, access constraints and tenant operations.
Main Contractors
Subcontract fabric and retrofit scope delivered to programme, with RAMS, ITPs, supervision and snagging discipline expected on tier-one sites.
Commercial Owners
Industrial, warehouse, office and mixed-use stock, fabric upgrades with suitability inspection and documented conformity on completion.
Agriculture / SMEs
Rural housing stock and farm dwellings, loft, cavity and IWI programmes with access planning and conformity handover.
Why It Matters
Fabric Performance, Suitability & Documented Quality
Procurement needs inspection criteria, installer competence and conformity records, not accreditation logos alone. Every claim is evidenced per project.
Fabric-First Performance
The measure that does most for warmth and carbon when done correctly.
Inspection & Suitability First
Pre-install inspection criteria and clear exclusions, so measures suit the property.
Documented Quality Control
Installer training and conformity documentation shown, not just accreditation logos.
Scope
What We Deliver
Cavity, loft and internal wall insulation delivered with pre-install suitability, trained installers and per-measure conformity records.
Cavity Wall Insulation
Suitability-inspected installs to standard.
Cavity Extraction & Re-Fill
Removal of failed insulation and re-fill where appropriate.
Loft Insulation
Top-up or full, with eaves ventilation maintained.
Internal Wall Insulation (IWI)
Design-stage risk control, thermal-bridge management and on-site supervision.
Suitability Inspection
Pre-install criteria and exclusions documented.
Conformity Documentation
Per-measure conformity records and lodgement.
Mobilisation & Delivery
Coordination Is The Differentiator
Portfolio surveys, suitability, design, programme, RAMS and site supervision, all run as one programme under framework agreements.
Portfolio Surveys & Suitability
Pre-install criteria, exclusions, damp and ventilation flags documented before work proceeds.
Design & Specification
Measure selection, RdSAP alignment, IWI design controls and thermal-bridge management.
Programme & RAMS
Framework programme, resident comms, access coordination, RAMS, ITPs and site induction.
Site Supervision
Trained installers, on-site supervision, ITPs and thermal-bridge checks, especially on IWI delivery.
KPIs & Reporting
Visible Performance, Documented Accountability
Buyers see what's happening on programme, on H&S, on quality, on conformity records and on social value, in formats their boards and panels expect.
Programme Adherence
Weekly programme reporting against the agreed schedule, with early-warning of risk.
Health & Safety
RAMS, ITPs, permits, induction and incident reporting documented and shared.
Snagging & Quality
Snag list management with closure evidence, photo records and sign-off.
Commissioning & Records
PAS 2030 conformity records, TrustMark lodgement evidence and handover packs per measure.
Carbon Reporting
Project-level carbon reporting in the buyer's format. Claims evidenced, not generic.
Social Value Reporting
Local jobs, apprenticeships, supply chain and community benefit reported per project.
Compliance
Accreditations & Insurances
The diligence pack, up front. Renewal dates published so your procurement team isn't chasing.
For cavity insulation, we document inspection criteria and exclusions before install. For internal wall insulation, design-stage risk control, thermal-bridge management and installer competence are the delivery-risk differentiator. PAS 2030 conformity and TrustMark lodgement are completed per measure, claims evidenced per project.

Funding & Programme Routes
Direct Procurement, ECO Or Framework
Insulation retrofit programmes can be delivered under direct procurement, ECO or SHDF funding routes, or through an existing framework agreement. Scope and funding structure are confirmed in writing per project.
Direct Procurement
Buyer-funded programme with written scope, suitability criteria and conformity records per property.
ECO / SHDF
Funded or part-funded routes where eligibility and measure suitability are documented before install.
Framework Agreement
Call-off delivery under an existing framework with programme reporting and conformity handover.
Our Process
1
Survey & Suitability
Portfolio or property-level survey, pre-install criteria, exclusions and damp/ventilation checks documented.
2
Design & Specification
Measure selection, IWI design controls and thermal-bridge management, written specification per property.
3
Install & Supervise
Trained installers, RAMS, ITPs, on-site supervision, especially IWI delivery risk.
4
Conformity & Sign-Off
PAS 2030 conformity records, TrustMark lodgement, handover pack and sign-off to the buyer.
Trust & Track Record
What Procurement, Asset Managers & Main Contractors Say
"CRS ran our loft and cavity programme across the estate with documented suitability checks on every property, exclusions were flagged early, not after install."
"Mobilised quickly under our framework, coordinated access with our FM team and handed over conformity records without us chasing."
"The IWI specification included thermal-bridge detail and supervision records we could actually use at panel. That was the differentiator."
FAQ
Procurement & Delivery Questions
- Are you framework-ready for council and housing-association procurement?
- Yes. We work with councils, housing associations, facilities managers and main contractors under framework agreements, with RAMS, insurances, PAS 2030 conformity and reporting expected at that level. A current capability statement is available on request.
- Do you handle portfolio insulation rollouts across multiple properties?
- Yes. We mobilise portfolio surveys, sequence suitability checks and install programmes across stock, rather than one-off jobs. Programme adherence, H&S, conformity records and snagging are reported back to the buyer.
- How do you manage suitability and exclusions before install?
- Every property is assessed against pre-install inspection criteria before work proceeds. For cavity insulation, documented criteria and exclusions are recorded. Where a measure is not suitable, that is stated in writing, not overridden to hit a target.
- What about internal wall insulation delivery risk?
- IWI is specified with design-stage risk control, thermal-bridge management and on-site supervision. Installer competence and conformity documentation are part of the delivery model, not an afterthought.
- Do you provide PAS 2030 conformity and TrustMark lodgement?
- Yes. Per-measure conformity records and TrustMark lodgement are completed as part of sign-off. Claims are evidenced per project, not quoted generically.
- Is a capability statement available?
- Yes. We provide a current capability statement and accreditation pack on request, with renewal dates for each accreditation and insurance to reduce diligence friction.
