What Lincoln houses usually score
The rating follows the construction, and Lincoln's construction follows its history. Knowing which kind of house you have tells you most of what the certificate will say before anyone visits.
- Victorian and Edwardian terraces, West End, Monks Road, Sincil Bank, Newport: solid brick walls, usually D or E. The cheap measures lift most to the top of a D; a C needs the wall insulated
- 1930s semis, Boultham, Bracebridge, St Giles: cavity walls, often unfilled. A C is readily reached with the cavity filled and a modern boiler
- Post-war estates, Ermine, Birchwood, Hartsholme: cavity-walled and frequently insulated already. C is common; controls and lighting finish the job
- New-build, the last twenty years: B is typical and the certificate from the developer is usually still valid
- The villages off the gas grid, oil or LPG heated: E and F are common because of the fuel cost weighting, regardless of how well the house is built
