New builds, extensions and testing, Scottish Borders
Ventilation for new builds, extensions and lofts in the Scottish Borders
Ventilation designs, MVHR or extract installs and the commissioning paperwork building control needs, across the Scottish Borders.
- From £4,750 inc VAT per home
- Free survey
New homes, extensions and loft conversions need ventilation that meets the building regulations and is tested before sign-off. We design the system, install it at the right stage of the build, measure the airflows and provide the commissioning information building control asks for.
The Scottish Borders has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

What the work involves
We work for self-builders, small developers, builders and architects. Fitting ducts at first fix is far cheaper than retrofitting, so it pays to involve us before the ceilings go up.
Commissioning only
Testing and paperwork for systems installed by others.
MVHR for new builds
Design, first fix, second fix and commissioning for whole-home heat recovery.
MEV or dMEV
Continuous extract systems where MVHR is not specified.

Which towns in the Scottish Borders do you cover?
All of the Scottish Borders, including Galashiels and Hawick. If your town is not listed, send the postcode and we will confirm.
When should MVHR be fitted in a new build?
MVHR ducts should go in at first fix, after the structure and before plasterboard. Planning it at design stage avoids clashes with joists and steels.
How much does MVHR cost in a new build?
For a 3 to 4 bedroom new build, MVHR fitted at first fix usually costs £4,950 to £7,950 including VAT. VAT on new-build work can differ, so we confirm the treatment on your quote.
Are prices different in the Scottish Borders?
Our guide prices are adjusted by region. In the Scottish Borders we use Scotland rates, so MVHR in a new build or full renovation (fitted at first fix), 3 to 4 bedrooms is typically £4,750 to £7,650 inc VAT per home.
Is the survey free in the Scottish Borders?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
