1. External Housing Investment 2025/26
The external housing investment programme continues to prioritise improvements in energy
efficiency across homes in Renfrewshire through the installation of External Wall Insulation
(EWI).  This investment  reduces heat loss, lowers carbon emissions and supports the
Scottish Government’s national Net-Zero ambitions, the Energy Efficiency Standard for
Social Housing (EESSH) and Scottish Housing Quality Standard (SHQS).  It also  aligns with
the Council’s wider strategic approach to climate change and sustainability.
In addition to energy efficiency improvements, the external housing investment programme
delivers essential fabric and renewal works.  This may include a combination of roof and
gutter replacement, renewal of external render finishes, windows and door renewals, solar
PV and improvements to loft insulation.
Collectively, these enhancements extend the lifespan of the housing stock, enhance
building performance and contribute to improved living conditions for residents.
During 2025/26, at total of 781 homes benefitted from a range of external improvement
works, with 1132 installations completed. Some properties will have received more that one
installation as part of the works – EG a combination of external works, solar PV and new
windows.
A breakdown of the external works carried out in 2025/26 is set out in the table below:

An example of the works completed as part of the external housing investment programme
during 2025/26, is the project at 74 Seedhill Road within the  housing regeneration area at
Auchentorlie in Paisley.
This block along with a further eight blocks in the Auchentorlie and Howard Street areas
received significant upgrades including EWI, roof and gutter replacement,  windows and
door replacement, solar PV,  loft insulation.
In addition to the regeneration works in Paisley, many villages and towns within Renfrewshire
have also received similar enhancements across diverse property types, reflecting the
varied nature of the housing stock across the area.
MP Group have a cumulative contractor KPI score of 96% against a 90% target. This score is
calculated as a weighted average across key performance areas, including timescale delivery,
contractor progress reporting, health and safety, recycling performance, application for payment,
and community benefits.

This was the first tenement block to be completed within the Housing Regeneration and
Renewal (HRR) areas.
The project adopted principles from the EnerPHit standard, a high performance retrofit
standard that enables existing buildings to achieve 75% – 90% energy savings alongside
enhanced comfort and enhanced structural performance .
EnerPHit serves as a practical and deliverable alternative to the full Passivhaus standard
(extremely energy-efficient buildings requiring minimal heating or cooling) which is typically
applied to new build developments aiming to achieve Net Zero targets.
The key elements delivered as part of the pilot were:
b) 74 Seedhill Road – Regeneration Pilot Project
HOUSING ASSET AND INVESTMENT PROGRAMME 2025/26 UPDATE
Improved Insulation: The block has been upgraded with the installation of
external wall insulation boards, underfloor insulation and loft insulation to
minimise heat loss through the building fabric.
Airtightness: The block is as airtight as possible through sealing gaps and cracks
in loft and roof space as well as in individual properties to prevent unwanted
draughts. This helps maintain a stable indoor temperature and reduces the need
for excessive heating or cooling. Underfloor insulation is also installed in ground
floor properties where possible.
High-Performance Windows and Doors: Installing triple-glazed windows and
well-insulated internal and external doors to flats as well as the installation of a
high spec common close door greatly improves the building’s energy efficiency by
reducing heat loss and preventing cold spots. This has also been applied to
common windows and doors of the block. Maintaining minimum temperatures
throughout the building will help to eradicate condensation/dampness.
Mechanical Ventilation with Heat Recovery (MVHR): An MVHR system is used in
all homes within the block to provide fresh air while recovering heat from outgoing
air. This helps maintain good indoor air quality without losing valuable warmth.
Every room in each of the flats has had ventilation units installed.
Minimising Thermal Bridges: Energy-efficient renovations focus on reducing
thermal bridges—areas where heat can escape easily - such as around windows
and at junctions between walls and floors. Various measures including taping and
foaming gaps around windows and doors play a vital role in minimising thermal
bridges and maintaining a continuous insulating barrier thus helping to reduce
heat loss.

This pilot retrofit project was undertaken to demonstrate and evaluate the benefits of
delivering high-performance energy efficiency measures in an existing residential block.
Internal enhancements were also delivered, including new kitchens, bathrooms and boilers.
As external works were completed in early 2026, the project will now undertake a period of
post completion evaluation through temperature and humidity monitoring using in home
sensors.
The retrofit of 74 Seedhill Road was intentionally delivered as a small-scale pilot, that would
help assess the future feasibility of such an intrusive approach to retrofitting older property.

Adjacent to  74 Seedhill Road , eight other fully Council owned blocks in Auchentorlie also
received external upgrades. An architectural design was produced in the early stages of the
project to capture the look and feel of an energy enhanced version of the blocks at
Auchentorlie. The final design was delivered bringing the original concept to life.

Houston Place in Elderslie was the first terraced Council block  to replace gas central
heating with clean heating. Air Source Heat Pumps (ASHP) have been installed to provide
highly efficient, renewable heating and domestic hot water by extracting heat from the
outside air into each property.
Complete in October 2025, this project demonstrated a whole house retrofit approach to
eight terraced homes and was supported by grant funding  of £254,000 from the Scottish
Government to deliver this Net Zero pilot project. As well as the air source heating system,
further property enhancements including solar PV, EWI, Mechanical Ventilation with Heat
Recovery (MVHR)  designed to provide continuous fresh, filtered air while retaining up to
95% of heat from extracted air have been utilised.
The properties also benefitted from internal improvements including new kitchens and new
radiators. Further energy efficient enhancements have been introduced - double glazing
replaced with triple glazing, replacement of external doors (including new porch) loft
insulation top-up and thorough air tightness measures to alleviate tenant fuel costs and
provide comfortable, high performing energy efficient homes.

This pioneering project will see the replacement of the gas infrastructure in two high-rise
blocks in Gallowhill, Paisley, with sustainable, clean heating for residents. In April 2025, the
Council obtained grant funding of £1.8m from the Scottish Government to support a project
to provide 180 homes with sustainable and clean heating by taking heat from the ground to
replace fossil fuelled boilers.
This project represents the first time a local authority in Scotland has deployed a ground
source heat pump system of this nature and scale, placing Renfrewshire Council at the
forefront of clean heating innovation in Scotland.
On-site pre-enabling works commenced in August 2025 followed by a borehole network
drilling exercise to enable the extraction of renewable heat energy from the earth, which will
be delivered to each flat via individual ground source heat pumps - discreet units designed
to fit inside a cupboard that deliver high-efficiency heating and hot water.
Drilling of the borehole network was successfully completed in December 2025, followed by
significant groundworks which were completed in May 2026. The next phase of works
includes the riser installation which will carry the ground sourced heat into all 180 homes. 
Following this, each flat will have new heat pumps and radiators installed and the existing
gas heating system removed, with the new system expected to be fully operational by the
end of this year.

Internal investment in Renfrewshire’s housing stock continues with improvement works
delivered to over 1000 homes in the last year. The table below  provides details of the
combination of measures that were completed during 2025/26, with both building services
and the Council’s appointed contractors delivering internal improvement works in both
tenanted and void properties.
Despite experiencing some initial challenges in the early phases of this year’s internal
investment programme, a high standard of quality of work has been maintained across the
kitchen, bathroom and rewire installations. Tenant  feedback has been positive, particularly
in relation to workmanship, communication and displays of professionalism reflecting the
customer focused approach taken for these works.
A contract was awarded in January 2026 which will see over 3000 properties benefitting from
kitchen, bathroom and electrical rewiring works over the next four years.
