Executive Summary 
The Housing Committee (the Committee”) is asked to approve the award of a contract for the
Replacement of Windows and Doors (2023 – 2025) (the ‘Contract’) to: 
• Lot 1 – Walker Profiles Limited 
• Lot 2 – Belac Group Limited 
The Contract is for an initial period of nine (9) months anticipated to commence on 03 April 2023.
The Council reserves the right to extend the Contract for additional periods up to a maximum of a
further 12 months. 
The maximum value of the Contract shall not exceed Fifteen Million Pounds Sterling
(£15,000,000.00) exclusive of VAT. The value of the Contract is split across both lots with
£10,000,000 applicable to Lot 1, and £5,000,000.00 applicable to Lot 2. As a “Measured Term
Contract” form of agreement, the value of the Contract is pertinent to demand therefore there is no
guarantee that the Councils spends any or all of the awarded contract value. 
Recommendations 
It is recommended that Committee approves the award of the Contract at the maximum value of
Fifteen Million Pounds Sterling (£15,000,000.00) exclusive of VAT to: 
• Walker Profiles Limited for Lot 1 up to the maximum value of Ten Million Pounds Sterling
(£10,000,000.00) exclusive of VAT 
• Belac Group Limited. for Lot 2 up to the maximum value of Five Million Pounds Sterling
(£5,000,000.00) exclusive of VAT 
This recommendation follows the completion of a procurement procedure, where the tender
recommended for award has been evaluated as providing the most economically advantageous
tender in terms of cost and quality for the Council.

The Plan for North Lanarkshire 
Priority Improve economic opportunities and outcomes 
Ambition Statement (1) Ensure a housing mix that supports social inclusion and economic
growth 
1. Background 
1.1 The requirements within the Contract are currently under contract. This contract is due to
expire on 26 March 2023 with the Contract detailed within this report due to supersede it. 
1.2  As part of the Councils ongoing “Capital Programme”, there is a requirement for window and
door replacements throughout the Councils housing stock including ‘four in a block’, semi-
detached, low rise and high rise properties etc. 
1.3 The scope of works within the Contract includes but is not limited to the following: 
• Removal of existing finishes, removing doors/composite screens, 
• removing timber or UPVC windows of various sizes;
• removing existing plumbing and electrical installations (where it presents an issue with
new installs, etc.);
• supply and fit of like for like replacement doors and windows of various size, any
mineral wool slab cavity barriers, any associated pointing and mastic works; 
• new kitchen and bathroom ventilation, axial fans to windows, refixing etc; and 
• reinstating any previously removed installations including fans etc. or finishes
including paint and plaster. 
1.4 To enable adequate service provision, the requirements of the Contract have been split
across two (2) lots, with each lot having a set maximum value of work orders the appointed
contractors could be issued. This approach allows the Council to spread the workload across
multiple contractors therefore ensuring delivery of requirements can be met depending on
appointed contractor’s availability and capacity at time of order. 
1.5 Accordingly, tenderers were free to bid for both lots 1 and 2 however, should a tenderer be
recommended for lot 1, their tender for lot 2 (if bidding for both lots) would be excluded on
the basis of the Councils intention to appoint a single / separate contractor to each lot. 
2. Report 
2.1 A user intelligence group (the ‘UIG’) of technical and procurement representatives was
formed to review technical specifications, discuss trading processes, market conditions and
trends, ways to maximise community benefits and sustainability and to agree the
procurement strategy that would deliver maximum benefit for the Council via the Contract. 
2.2 The initial estimated value of the Contract dictated that the procurement procedure be
undertaken in accordance with the Public Contracts (Scotland) Regulations 2015. An advert
for the contract opportunity was published on the Public Contracts Scotland and the UK Find
a Tender (FTS) website.

2.3 The procurement procedure was undertaken as an “Open Procedure” Based on the
evaluation criteria and scoring methodology set out in the invitation to tender package within
the procurement procedure, an evaluation of tender responses was completed by members
identified by the UIG. Selection stage responses were assessed first and compliant tenderers
that satisfied / declared that they met the published minimum selection stage criteria
progressed to the award stage evaluation. Following identification of the recommended
tenderer(s), their selection stage responses were assessed in more detail to ensure they
satisfied the minimum selection stage criteria applied 
2.4 The Contract award recommendation is made on the basis of the two tenderers who
submitted the most economically advantageous tender. 
2.5 The tender(s) as detailed below have been evaluated as representing the most economically
advantageous tenders for this Contract: 
• Lot 1 – Walker Profiles Limited 
• Lot 2 – Belac Group Limited 
2.6 Appendix 1 confirms the scoring achieved by each tenderer, further details of the
procurement procedure is provided in Appendix 2 and the SME status and location of all
tenderers is located within Appendix 3. 
2.7 The maximum value of the Contract shall not exceed Fifteen Million Pounds Sterling
(£15,000,000.00) exclusive of VAT. The value of the Contract is split across both lots with
£10,000,000 applicable to Lot 1, and £5,000,000.00 applicable to Lot 2 
2.8 The costs associated with contract delivery will be contained within the Housing Capital
budget for Housing Property Services. 
Price Savings / Increases 
2.9 The pre-tender whole life estimate for the Contract was £15,000,000.00. This is the maximum
value of the Contract as identified and set by the Council and as a measured term contract
there is no obligation on the Council to spend any or all of this value. 
When comparing rates to with the existing contract tendered in 2019, tendered rates for this
Contract have increased by approximately 40%. These increased costs can be attributed to
a multitude of factors including the Covid pandemic, the ongoing war in Ukraine, increased
construction material costs, and increased labour costs brought about by the sharp rise in
inflation and other cost of living pressures i.e. utility / fuel costs. 
As a result of the increased costs associated with the Contract, there will be a subsequent
reduction in the number of homes to be included within this phase of the Council’s Windows
and Doors Replacement Programme when compared to the previous contract.
