Remote-first SAP calculations for Swansea projects
Design-stage and as-built SAP calculations for new homes, conversions and extensions in Swansea, assessed against the Welsh Approved Document L. Swansea projects are handled mainly from drawings and specifications, which is how most SAP work is done anyway. Where a site visit adds value at completion, we'll agree it with you in the quote.

SWANSEA PROJECTS
Swansea Projects We Can Help With
✓ Stone and solid-wall buildings converted into homes, including former chapels, shops and outbuildings, where existing walls often need careful U-value assumptions.
✓ Coastal and hillside plots where exposure, orientation and large view-facing glazing need balancing against Part L targets.
✓ Holiday-let and new-home builds on the Gower and in surrounding villages, often off the gas network.
✓ Extensions with glazed gables or roof lanterns on homes across the city and the Swansea Valley.
LOCAL REQUIREMENTS
Getting Swansea Projects Through Part L
Swansea projects follow the Welsh Approved Document L. With conversions of older buildings, the existing fabric is often the weak point, so we look early at where upgrades give the biggest benefit for the money.
Send us the Building Control comments if you already have them. We'll respond to each point and update the calculation so the submission can move forward.
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 Swansea: Questions
Do you need to visit my Swansea site?
Usually not for the design stage, which is produced from drawings. At completion we need the final specification and air test result, and we'll agree any site visit in advance.
Can you do SAP for a chapel or barn conversion?
Yes. Conversions that create new dwellings normally need a SAP-based EPC. We'll advise on realistic assumptions for the existing walls and the most effective upgrades.
How do I send drawings?
Email or WhatsApp PDFs or CAD exports, or use the quote form on this page and we'll reply with where to send them.
