As the Asset Sustainability Manager, you will serve as the analytical engine behind a large-scale housing retrofit programme. You will take ownership of energy performance data, translating property audits and SAP modeling into actionable investment plans that drive home improvements across the country. Your day-to-day involves overseeing the lifecycle of energy efficiency projects, from initial identification of improvement opportunities to the final verification of performance outcomes.

This role is a vital link between climate goals and social equity. By decarbonizing residential assets, you are directly mitigating fuel poverty for thousands of diverse customers while significantly lowering the carbon footprint of the UK’s housing stock. It is a rare opportunity to see high-level sustainability strategy manifest as warmer, healthier, and more affordable living spaces for vulnerable communities.

This suits someone who possesses a sharp analytical mind and deep technical knowledge of residential retrofit standards like PAS 2035. You should be equally comfortable navigating complex energy data and collaborating with external consultants to ensure high-quality delivery.

Job FAQs

What are the main missions and responsibilities of this role?

The primary mission is to manage and analyze the technical data that underpins Stonewater’s decarbonization and retrofit strategy. You will be responsible for energy modeling and identifying which properties require investment to meet efficiency standards. Beyond data analysis, you will oversee the compliance and reporting of grant-funded programmes. This involves ensuring that all energy improvement measures align with national regulations and that environmental outcomes are accurately documented and reported. Finally, you will serve as a technical gatekeeper by reviewing and approving recommendations from external retrofit coordinators. Your goal is to ensure that every investment contributes meaningfully to the organization's sustainability targets and customer comfort.

Key learning opportunities for this job

You will gain deep expertise in the application of PAS 2035 and RdSAP modeling within a large-scale corporate environment. This provides a front-row seat to how national housing policy translates into operational asset management. There is significant exposure to green finance and grant management, specifically regarding the Social Housing Decarbonisation Fund (SHDF) or similar schemes. Mastering the compliance requirements for these funds is a highly marketable skill in the current UK housing market. You will also develop leadership and project management skills by coordinating between environment teams, surveyors, and external consultants, gaining a holistic view of the sustainable construction and renovation lifecycle.

How does the ideal candidate look like (experience, skills)?

The ideal candidate brings a blend of technical energy knowledge and robust analytical skills. You should be well-versed in residential energy efficiency measures and the software tools used to calculate them, such as SAP or enterprise-level asset management databases. Experience working within social housing or the non-profit sector is highly advantageous, as is a proven track record of managing grant-funded programmes. You must be able to prove your ability to turn raw data into strategic insight. Communication is key. You need to be able to explain complex technical retrofit solutions to non-expert colleagues and stakeholders, ensuring that the mission of sustainability is understood and supported across the business.

Advice to stand out and make a successful application

Detail your specific experience with PAS 2035 and RdSAP modeling. General sustainability knowledge is great, but Stonewater needs to see that you understand the technical nuances of residential property decarbonization. Quantify your previous impact. If you have managed grant funding or property improvements before, mention the scale of the budget or the number of units affected. Showing that you can handle a portfolio of 40,000 homes is a must. Tailor your cover letter to reflect Stonewater’s social mission. They aren't just looking for an analyst; they want someone who understands how energy efficiency improves the lives of residents and tackles social inequality.

What aspects of the company's sustainability is this role likely to focus on?

This role is central to the Environment & Sustainability team's efforts to reach Net Zero. The focus is specifically on the 'Environmental' and 'Social' pillars of ESG, through building decarbonization and the alleviation of fuel poverty. You will likely focus on Scope 3 emissions related to the energy used by residents in Stonewater homes. By improving insulation and installing renewable heating, you are physically transforming the asset base to be future-proof. There is also a strong focus on data integrity and transparent reporting. Ensuring that sustainability claims are backed by rigorous energy modeling is a core part of the role’s contribution to corporate governance.

What are the main challenges someone in this role might face?

One of the primary challenges is data fragmentation across a large, diverse portfolio of 40,000 homes. You may spend significant time reconciling different data sources to get an accurate picture of energy performance. Navigating the evolving regulatory landscape in the UK, including changes to SAP software and government funding criteria, requires constant vigilance and the ability to pivot strategies quickly. Balancing technical requirements with social needs can also be tough. Ensuring that retrofit measures are both effective for the building and non-disruptive or affordable for the customers requires a high degree of empathy and coordination.

How could a typical day look like for someone in this position?

A typical day might start with analyzing energy models to identify the next batch of properties for the retrofit programme. You will likely spend time reviewing reports from external coordinators to verify their technical recommendations. Afternoons often involve cross-functional meetings with the investment and finance teams to discuss grant compliance and budget forecasting. You might also provide guidance to site teams regarding specific energy efficiency measures being installed. You will finish the day by updating sustainability performance dashboards, ensuring that the senior leadership team has an accurate view of progress against the organization's carbon reduction targets.

What are the opportunities for professional growth and development in this role?

Within a large organization like Stonewater, there are clear paths toward Senior Asset Management or more specialized Strategic Sustainability roles. You are positioned at the intersection of two high-growth fields: ESG and Property Tech. You may have the opportunity to lead national-level pilot projects for new decarbonization technologies, giving you high visibility within the UK social housing sector. The role offers a platform to become a subject matter expert in sustainable housing, potentially leading to advisory roles or higher-level strategy positions within the Environment & Sustainability department as the team expands.

The main stakeholders you might be interacting with

You will report directly into the Environment & Sustainability team, collaborating closely with colleagues in Asset Management and Investment. Externally, your primary contacts will be Retrofit Coordinators and energy consultants. You will be their main point of contact for technical approvals and performance monitoring. You will also interact with government funding bodies regarding grant compliance and occasionally engage with residents/customers to help explain the energy benefits of the improvements being made to their homes.
