NG32 Grantham and Bourne
South Kesteven Rating D Score: 57 / 100

NG32 is below average for energy efficiency — most homes here have room to improve.

11.9% of homes are rated F or G — above the national average of 2.9%.

Based on 3,975 Energy Performance Certificates, NG32 in South Kesteven has an average EPC score of 57 out of 100, placing it below the national average. To put this in context, the national average sits at 67. The most common rating band is D, with 8.5% of homes rated A or B and 50.5% in the C or D bands. Meanwhile, 11.9% of homes sit in the F or G bands — the least efficient categories. In practical terms, a rating of D means many homes here lose more heat than average — potentially adding £200-400 per year to energy bills compared to a C-rated home.

Most of the housing stock here consists of houses. Around 71% of properties are owner-occupied . Oil-fired heating is common in this part of NG32, reflecting the more rural character of the area and limited mains gas coverage.

There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 57 to 79 — a 22-point jump that would lift the typical rating to C. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions

What is the average EPC rating in NG32?

Homes in NG32 have an average EPC rating of D, scoring 57 out of 100 for energy efficiency. That figure comes from 3,975 certificates issued across the district.

That is below the national average of 67, which means there is real scope to improve energy efficiency here. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.

What percentage of homes in NG32 are rated F or G?

11.9% of homes in NG32 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

That means NG32 has a higher-than-average proportion of poorly insulated homes. On the positive side, many of these properties may qualify for free improvements through government schemes like ECO4 or the Great British Insulation Scheme. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
