Heating Upgrade Framework

Gentoo currently has 29,026 properties located in predominately 4 geographical management areas in the City of Sunderland, Houghton/Hetton and Washington.

Within this housing stock 28,324 are tenanted properties and 702 are leasehold.

The numbers of tenanted and leasehold properties may vary throughout the duration of the Programme.

Gentoo have pledged that all properties under its ownership that currently occupy an EPC rating of band "D" or lower will receive the necessary measures required to improve this rating to a minimum of band "C" by 2030.

At the time of this Tender documentation being prepared, it is anticipated that there are approximately 7,000 properties which require some form of work to enable this pledge to be realised.

Properties are eligible to receive a large number of additional SAP points via the works completed as part of this Tender.

Thereafter, Gentoo will release numerous further Tender opportunities to allow this pledge to be achieved.

This is the first Tender opportunity, and relates to Heating Upgrade Works.

The Tender is broken into 2 separate Lots, as follows: - Lot 1: Planned & Responsive Boiler Replacements; and - Lot 2: Back Boiler Removals, Boiler Installations and Secondary Heating Removals.

Within Lot 1, there are currently 401 planned boiler replacements scheduled to be completed over a 2-year period, and it is estimated there will be approximately 800 responsive installations per year - however, this number is subject to fluctuation.

Within Lot 2 there are currently 225 boiler replacements, 48 back boiler and gas fire installations to be removed completely and replaced with a condensing combi boiler and there are 225 gas and electric secondary heating removals to be completed.

Regardless of whether the works are planned or responsive, the scope of the work will effectively be the same, and those works will include, but may not be necessarily limited to, the following across the 2 Lots: - Installation of combination gas boilers; - Installation of system gas boilers; - Installation of radiators; - Upgrade of existing heating control systems; - Cylinder insulation and replacement; - Replacement of full distribution systems ; and - General Building Works in relation to energy performance. - Removal of back boilers; - Removal of secondary heating appliances including all making good.

Each Lot will run for separate durations.

Those durations are as follows: - Lot 1; four years, commencing in June 2024 and concluding in June 2028; and - Lot 2; two years, with 2 optional extension clauses of 12-months each, maximum duration of four years.

Commencing in June 2024 and set to conclude in June 2026.

Gentoo will notify the Providers in early 2026 if the first of the available optional extension clauses is to be utilised.

Gentoo will establish a Framework for each Lot.

The number of Providers on each Framework is still yet to be determined, but will be confirmed within the Tender documents.
