BATH PROJECTS
Bath Projects We Can Help With
✓ Conversions of Bath stone townhouses and mews buildings into flats, often in conservation areas where external insulation isn't an option.
✓ New homes on infill plots and in villages across Bath and North East Somerset.
✓ Contemporary extensions to period homes with large areas of glazing.
✓ Small residential schemes that need to meet the council's net zero planning policy as well as Building Regulations.
LOCAL REQUIREMENTS
Net Zero Planning Policy in Bath
Bath projects are assessed against the English Approved Document L for Building Regulations. Separately, Bath and North East Somerset Council has net zero planning policies for new homes. These are checked by running SAP results through the council's SAP Conversion Tool, which looks at space heating demand (below 30 kWh/m² a year), total energy use (below 40 kWh/m² a year) and on-site renewables at least matching total energy use.
If your planning permission includes these requirements, tell us at the start. We can produce the SAP outputs the tool needs, and the earlier the targets are tested, the less chance of a costly redesign.
HOW IT WORKS
Two Stages, One Assessor
1
Design stage
From your drawings we produce the design-stage SAP and Predicted Energy Assessment for Building Control, and flag anything that won't pass.
2
During the build
Let us know about any specification changes and we'll check them before they're installed.
3
Completion
We update the calculation with the as-built details and air test result, then lodge the On-Construction EPC.
Full details of every SAP service are on our main SAP calculations page.

SAP Calculations in Bath: Questions
Can you help with the B&NES net zero policy?
Yes. We produce the SAP calculation and the outputs used in the council's SAP Conversion Tool, so you can see early whether the design meets the space heating, energy use and renewables targets.
Do you work on listed or conservation-area buildings in Bath?
Yes. Part L allows for the special character of historic buildings. We model realistic upgrade options and flag where Building Control or the conservation officer may need to agree a balanced approach.
Do you have an office in Bath?
No. We are based in Cardiff and work on Bath projects from drawings and specifications. Any site attendance is agreed in the quote.
