    Tier 1 Joinery for Prime Central London: What HNW Clients and Architects Should Specify

    Last updated: April 2026. By the Reeve & Co studio team.

    “Tier 1” is a term construction managers use to describe their top tier of trades — the contractors and sub-contractors they will allow on a Prime Central London (PCL) job that is insured, scrutinised and watched by the client every week. For bespoke joinery, the Tier 1 standard is the minimum expectation on most projects in Mayfair, Belgravia, Knightsbridge, Chelsea, Kensington, Marylebone and St John’s Wood.

    This article sets out what Tier 1 actually means for a joinery package in PCL, what HNW clients and architects should look for, and how the workflow differs from a standard residential commission.

    1. The PCL boroughs and what makes them different

    PCL is loosely defined as the seven postcode clusters where average residential prices exceed £2,500 per sq ft: Mayfair, Belgravia, Knightsbridge, Chelsea, Kensington, Marylebone and St John’s Wood. Three things distinguish a joinery commission in these boroughs from any other UK address:

    • Building stock — mostly Georgian or Victorian terraces, frequently listed, in conservation areas, with stringent local-authority controls (City of Westminster and Royal Borough of Kensington & Chelsea are the strictest in England).
    • Construction managers run the site — firms like Walter Lilly, Faithdean, Knowles, R W Armstrong, 4C, Broadland and West Green operate as the “Tier 0” on these jobs and pre-vet every supplier.
    • Client expectations — HNW clients typically have an architect, an interior designer and a project manager all reviewing the joinery package. Tolerance for snags is near zero.

    2. What “Tier 1” means in practice

    When a Tier 0 main contractor calls a joinery shop “Tier 1”, they mean the shop has demonstrably cleared all of these:

    • £10m public liability insurance as a minimum — many PCL projects ask for £25m.
    • £5m+ professional indemnity covering bespoke design.
    • Independent vetting — financial accounts, CIS/HMRC standing, GDPR compliance, modern slavery policy, and at least two reference projects on similar PCL addresses within the last 24 months.
    • Health & safety — CHAS or SafeContractor accreditation, full RAMS for every install package.
    • Lead-time discipline — the joinery programme integrates into a master programme with weekly lookahead reviews. Slippage on a PCL job costs the client £5k–£25k a week in extension-of-time and prelims.
    • Finish standards — visible joinery is hand-finished to a level that survives white-glove handover. This includes proper grain matching across panel runs, no visible fixings, French-polish or hand-rubbed lacquer rather than spray-only.

    3. Materials and finishes that pass white-glove

    Across our PCL projects, the recurring specifications include:

    • Quarter-sawn European oak, walnut or American black walnut — consistent grain, dimensional stability.
    • Solid versus veneer — solid stock for visible structural members, premium veneers (1.0mm+) on large flat panels to maintain grain match.
    • French polishing — on heritage projects and most reception-room joinery. Done in our workshop, not on site.
    • Hand-rubbed lacquer — for contemporary kitchens and wardrobes; we use a 7-stage process with sanding between coats.
    • High-gloss polyester — for piano-finish kitchens and feature panels. Demands a workshop with strict humidity and dust control.
    • Ironmongery — typically Joseph Giles, Samuel Heath, or bespoke pieces sourced through Cox London or A&H Brass.

    4. The CAD-to-installation workflow we use on PCL

    1. Concept review — we sit with the architect and interior designer, mark up the GA drawings, flag buildability and lead-time issues before tender.
    2. Tender response — itemised price, programme, and value-engineering options. We never tender below cost; clients pay for our depth on PCL.
    3. Shop drawings — 1:5 and 1:1 details for every junction. Issued for architect & designer comment, then frozen.
    4. Workshop fabrication — in our Suffolk workshop. Each piece tagged, photographed, and packaged for transit.
    5. Site delivery & install — our two-man install crews on PCL jobs are directly employed (not subcontracted) and CSCS-carded.
    6. Snag & handover — we attend the snag walk with the project manager, agree the punch list on the day, return within 10 working days to clear it.
