Preliminary Market Engagement - Refurbishment of Properties for Disposal – London and Hertfordshire
Authority: Sovereign Network Group
What is being bought
Published requirement descriptionSNG is exploring options for the refurbishment of selected dilapidated residential properties prior to disposal on the open market across London and Hertfordshire. The objective is to improve property condition, maximise capital receipts, and achieve efficiencies through a scalable delivery model.
An emerging option under consideration is the appointment of a Managing Contractor to oversee refurbishment works, with specialist works delivered by sub-contractors. This PME is intended to test the commercial and contractual viability of such approaches and to understand how risk, responsibility, and liability are commonly allocated within the market.
The geographical scope of the anticipated works is relatively broad, with primary activity expected across North and West London and surrounding areas. The highest concentration of properties is currently anticipated within the London Borough of Brent, with additional activity likely in Westminster and Barnet. Coverage may also extend north into East Hertfordshire, alongside smaller volumes of work across other London boroughs where suitable opportunities arise.
In terms of property type, the portfolio is expected to be predominantly Victorian residential stock, particularly Victorian house‑to‑flat conversions and subdivided Victorian houses. These properties typically originate as single‑family dwellings that have been converted into multiple self‑contained flats. They may retain period features and commonly present considerations relating to layout, structure, building services, fire safety, regulatory compliance, and long‑term maintenance.
While there may be scope for other residential property types to be included, Victorian properties are currently expected to form the core of the portfolio due to their prevalence within the target areas and the specific technical and compliance considerations they present. This description is indicative and provided to support market understanding rather than to define fixed scope or volumes.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
