Triple glazing for new builds and self-builds in Holywood
We arrange surveys and fitting of new-build triple glazing in Holywood and the BT18 area, with a written, fixed quote after a free survey.

Triple glazing that gives your energy calculation headroom. Triple glazing is not required by Building Regulations for new homes, but it helps a new dwelling meet its overall energy target.
Winter light and glass choice in Holywood
On the shortest day, Holywood gets about 7 h 14 min of daylight and the midday sun reaches only about 12° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

Rules for new builds and self-builds in Northern Ireland
For a new home in Northern Ireland, windows and doors are approved through the build’s full plans application to council Building Control: they must average 1.40 W/m²K, with no single unit worse than 3.00. The house itself needs planning permission.
VAT: supply and fitting by a VAT-registered contractor in the construction of a new home is normally zero-rated, so new-build guide prices are shown without VAT; supply-only purchases carry 20% VAT, which self-builders can usually reclaim through HMRC’s DIY housebuilders scheme.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions from Holywood
Is triple glazing mandatory for new builds?
No. Neither the current rules nor the Future Homes Standard make it compulsory. Triple glazing helps meet the overall energy target.
Can you price from drawings?
Yes. Send your drawings or window schedule and we will price a package, then confirm sizes on site before manufacture.
How long does it take to get new-build triple glazing fitted in Holywood?
After the survey, typical manufacture time is 6 to 12 weeks, and fitting is planned around your build programme.
Do I need permission for new-build triple glazing in Holywood?
In Northern Ireland, a new home needs planning permission, and its windows and doors are approved through the build’s own Building Regulations application rather than as replacements.
