The Association of North East Councils, operating through NEPO, is engaging suppliers on the next NEPO233 Retrofit and Energy Efficiency Works framework. The planning information indicates an estimated value of £500 million excluding VAT, or £600 million including VAT, over four years.
This is a specialist retrofit opportunity. It is likely to interest retrofit delivery partners, principal contractors, installers, assessors, coordinators, designers and low-carbon technology providers, depending on the final lot structure. It should not be framed simply for any business in the building-construction sector. To review likely fit, contact Thornton & Lowe.
Differences with the existing framework
NEPO233 is already recognised as a route to deliver retrofit and decarbonisation works. The 2026 notice concerns the development of the next arrangement. Suppliers should therefore separate evidence about performance under the current framework from assumptions about how the replacement will operate.
The geographic scope, lot structure, supplier numbers and call-off methods are expected to be shaped through engagement. Businesses should monitor those details closely, especially if they can only cover the North East or specialise in a single measure.
Which suppliers may be well placed?
Potential bidders include organisations able to manage whole-house or whole-building retrofit programmes, as well as specialists in insulation, glazing, heating, solar PV, ventilation, controls and related energy-efficiency measures. The final procurement may also require technical assessment, design, resident engagement, funding compliance and programme management.
A direct framework bid is most credible where the supplier can take responsibility for the full scope attached to its lot. Specialist installers may be better placed within a delivery partner’s supply chain if the lot requires end-to-end retrofit coordination.
Evidence to prepare
- Technical compliance: applicable certifications, competent people and controlled installation processes.
- Resident and customer journey: surveys, appointments, disruption management and complaint resolution.
- Quality assurance: design checks, inspection, testing, evidence capture and defect prevention.
- Programme capacity: labour, surveyors, coordinators, materials and regional delivery management.
- Funding and reporting: accurate records, audit-ready files and performance data.
- Social value: skills, employment and supply-chain commitments that are realistic for each delivery area.
Our guide to social value in tenders can help suppliers develop commitments that are specific, measurable and linked to the work.
Market engagement and next steps
The current engagement deadline is shown as 11 September 2026. Suppliers should review the official notice, complete any questionnaires and register for future procurement updates.
Use the planning period to map which measures you can deliver directly, identify delivery partners, check certification coverage and build case studies around measured energy, quality and resident outcomes. These preparations will be more useful than producing generic environmental messaging before the final questions are known.
