Grainger plc (GRI), the UK's largest listed residential landlord and a FTSE 250 company, has announced the results of its annual independent customer satisfaction survey, recording a Net Promoter Score (NPS) of +48 across its portfolio. That figure stands significantly ahead of the UK Build to Rent sector average of -4, according to the company's 9 November 2026 announcement. The results were achieved during a period of notable regulatory change in the UK rental sector, which the company says demonstrates the strength and scalability of its operational platform. Investors may be watching the data as a leading indicator of customer retention and occupancy performance across Grainger's approximately 11,300 rental homes.

  • Annual independent customer satisfaction survey recorded an NPS of +48, against a UK BTR sector average of -4
  • 74% of customers indicated intent to stay in their Grainger home; 90% said they really like their Grainger home
  • Investors should watch how retention and occupancy metrics translate into future operational and financial performance updates

Grainger's NPS of +48 Outperforms UK Build to Rent Sector Average of -4

The headline finding from Grainger's independently conducted survey is an NPS of +48, a metric that measures customer loyalty by comparing the proportion of promoters to detractors. The UK BTR sector average of -4 provides direct context for the scale of Grainger's outperformance. Additional survey data disclosed in the announcement shows that 86% of customers agree Grainger is easy to do business with, 85% consider it a brand they trust, and 90% say they really like their Grainger home — each figure pointing to consistent satisfaction across different dimensions of the customer relationship.

CONNECT Technology Platform and On-Site Teams Central to Grainger's Service Delivery Model

The announcement attributes the results in part to Grainger's proprietary CONNECT technology platform, which the company states supports data-led insights and enhances service delivery across the portfolio. On-site resident services teams are also highlighted as a core component, alongside amenities such as gyms, residents' lounges, roof terraces, co-working spaces, and 250MB superfast fibre optic broadband. The company states this combination improves operational efficiency and helps drive strong customer retention and occupancy — metrics that underpin the revenue model of a large-scale residential landlord managing roughly 11,300 homes for over 25,000 customers.

74% Customer Retention Intention Signals Occupancy Stability Amid UK Rental Regulatory Change

The announcement explicitly notes that the survey results were achieved during a period of significant regulatory change in the UK rental sector, a risk factor relevant to all residential landlords. Grainger's disclosure that 74% of surveyed customers intend to stay in their homes provides a forward-looking indicator of occupancy stability. The company has a secured BTR development pipeline of approximately 4,000 homes valued at £1.2 billion, meaning that sustaining high retention rates will become increasingly important as new stock enters the portfolio across multiple UK cities.

Helen Gordon Highlights Long-Term Platform Investment and Shareholder Value Focus

Chief Executive Helen Gordon stated that the results reflect an operational platform built over many years and the commitment of Grainger's teams to delivering a high-quality customer experience. She noted continued investment in technology, data, and people as the basis for improving both customer experience and operational scalability. Gordon added that Grainger's investments position the business to support future growth and deliver long-term value for shareholders. The company did not disclose specific financial metrics or updated earnings guidance alongside this announcement.
