Yes. The Star Ratings are based on the results of the National New Homes Customer Satisfaction Survey, an independent industry survey completed by new build buyers. The survey is validated by Ipsos and is entirely independent of any builder or builder group.

The National House Building Council (NHBC), Premier Guarantee and Local Authority Building Control (LABC) operate the survey to gather anonymous feedback.

There are a range of rules in place that all participating members must follow.

Star Ratings are based on feedback from the National New Homes Customer Satisfaction Survey, which is sent to buyers 8 weeks and 9 months after they move into their new home.

Builders are assessed on the responses to two survey questions: one about the quality of their home and one about the service they received. Each answer is scored on a scale from 1 to 5, where 5 means very satisfied and 1 means very dissatisfied.

Both questions are asked in the 8-week and 9-month surveys, giving four scores in total. These scores are averaged to calculate the overall rating, with responses scored from 1 (very dissatisfied) to 5 (very satisfied).

For the 2024/25 survey year, announced in March 2026, builders must achieve a score of 4.15 or higher to receive a 5-star rating. This threshold will increase in future years to continue improving customer service standards across the industry.

This data is updated every quarter, showing results for participating builders’ % scores for the key ‘Would you recommend you builder to a friend?’ question from the 8-week survey.

Participation in the National New Homes Customer Satisfaction Survey and HBF Star Rating scheme, and publication of results is voluntary.

Results from the survey can also be found on the New Homes Quality Board’s website. Moving forward the NHQB intends to make publication of data a requirement of its scheme.

HBF Star Ratings are updated annually and can be checked by viewing the current awarding year's results.

If the builder is displaying the wrong star rating, inform our team by emailing us at info@hbf.co.uk, including:

• The home builder’s name
• The home builder’s address
• Any details of the star rating and how it is being displayed (for example on a site flag or in sales literature)
• A photo, if possible

HBF Star Ratings are valid for one year, with new ratings announced each March. At that time, home builders must ensure they display their updated rating and replace any outdated materials so that all merchandise reflects the score for the current award year.

This means that participating home builders should only display their ratings for one year, in order to comply with the survey's rules.

HBF Star Ratings are based on an overall annual score and published in March each year. We also publish rolling 12-month rolling data quarterly. This enables home builders to monitor their performance and provides timely updates to home buyers.

• Q1 (house purchases completed Oct-Dec) data is published in June.
• Q2 (house purchases completed Jan-Mar) data is published in September.
• Q3 (house purchases completed Apr-Jun) data is published in December.
• Q4 (house purchases completed Jul-Sep) data is published in March.

Home builders can also chose to have this data published on the New Homes Quality Board's website to support home buyers in making informed decisions.

Yes, participating home builders can opt out of the scheme by notifying the Home Builders Federation (HBF) or Homes for Scotland (HFS). HBF will write to all participants at the end of each survey year to check whether they wish to publish that year.

Should a participant inform HBF or HFS (as appropriate) that they would not like to publish a Star Rating, they will still be permitted to publish in future years.

More details can be found in the scheme's rules.

Participating home builders have to have a full year of results before they are awarded a HBF Star Rating and receive indicative quarterly rolling % scores. Find out how your organisation can join the scheme.

Home builders achieving a five-star status will be invited to our Customer Satisfaction Survey awards.

Members taking part in the scheme can also order promotional materials to promote their Star Rating. This includes flags and plaques to display on your sites.

The National New Homes Customer Satisfaction Survey and HBF Star Rating Scheme is a voluntary scheme open to all HBF or Homes for Scotland (HFS) members.

Participating builders must comply with the scheme’s rules, which outline how scores are calculated and the conditions for opting out of publication. Once you have a full year’s results you will be awarded an annual star rating and receive indicative quarterly rolling % scores.
