New-build windows look simple: clean white uPVC, square reveals, no old paint to worry about. They also hide a few traps for blinds, from trickle vents and chunky handles to shallow reveals and fixings that have to go into plasterboard or steel. Checking these before you order saves a return visit and a blind that never quite works.
Quick answer: Before ordering blinds for a new-build home, check that the blind will not cover or block the trickle vents, that the fabric clears window handles and restrictors, how tilt-and-turn sashes open, how deep the reveals are, and what the brackets will fix into. Book after handover, once snagging is under way.
What should you check before ordering blinds for new-build homes?
Blinds for new-build homes need five checks before you order: where the trickle vents sit, how far the handles project, how each window opens, how deep the reveal is, and what the wall or frame is made of. Get those right and almost any roller blind will fit neatly. Miss one and the blind can clash with the window.
A quick walk round with a notepad helps. For each window, note:
- whether there is a trickle vent, and where on the frame it sits
- the type of handle and how far it sticks out from the glass
- whether the window opens outward, tilts inward or turns inward
- the depth of the reveal from the frame to the room
- any window restrictors, sensors or alarm contacts on the frame
With that list, you can decide on recess, exact fit or outside-recess fitting room by room, rather than choosing one method for the whole house.
Can blinds cover trickle vents on new-build windows?
Trickle vents are small ventilators, usually in the head of the window frame, that supply background ventilation. For new dwellings in England, Approved Document F expects them to be at least 1,700mm above the floor and says they are intended to normally be left open. A blind should not seal them shut.
That guidance comes from the 2021 edition for dwellings, which also says vents should be easy for the occupant to reach. Homes built to a later edition follow its own rules, but the principle is the same: the vent slider needs to stay usable.
There are three common ways to keep a roller blind and a trickle vent working together:
- Fit above the recess. Brackets go on the wall above the window, so the roll sits higher than the vent and the fabric drops in front of it with room for air to move.
- Fit in the recess, below the vent. If the reveal is deep enough, brackets can go on the reveal just under the frame head, leaving the vent clear.
- Exact fit to the frame. The blind sits on the frame beneath the vent, covering the glass only.
A blind hanging in front of a vent at night is normal. The problem is a bracket or headrail over the vent opening, or a slider nobody can reach. When we measure, we mark every vent and plan brackets around it.
How much clearance do window handles and restrictors need?
Window handle clearance is the gap between the glass and the back of a lowered blind, and it must be larger than the handle’s projection. New-build uPVC handles usually stand out from the frame by a noticeable amount, so a blind fitted too close will snag, bulge or stop short of the sill when pulled down.
Measure from the face of the frame to the outermost point of the handle, with the handle in its locked position. Then compare that with the depth available in the reveal. If the reveal is deeper than the handle projection plus the depth of the roller and brackets, a recess fit works. If it is not, the blind needs to come forward.
Options when the handle wins:
- fit outside the recess on the wall, with brackets that hold the roll clear of the handle
- use extension or projection brackets to push a recess-fitted roll forward
- fit an exact-fit blind to the opening sash, so the blind moves with the window
Window restrictors need the same thought. The blind should never hide a restrictor’s release catch, and alarm contacts on the frame must stay clear of brackets.
Which roller blinds work on tilt-and-turn windows?
Tilt-and-turn windows open inward in two ways: the top tips into the room for ventilation, or the whole sash swings in like a door. A roller blind fitted in the reveal will clash with both movements unless it is rolled up first, so the best fit is usually either high above the sash or fixed to the sash itself.
The choice depends on how you use the window:
| Fitting position | How it behaves | Best for |
|---|---|---|
| Outside recess, above the frame | Roll up the blind, then tilt or turn the window freely underneath it | Windows you open occasionally, rooms where you want full coverage |
| Exact fit on the sash | Blind moves with the window, so it can stay down while tilted | Bedrooms where you want air and privacy at the same time |
| Inside recess, at the top of the reveal | Works only if the sash clears the rolled-up blind when fully turned | Deep reveals with plenty of headroom above the frame |
A turned sash swings across the reveal, so side brackets and chain retainers must sit outside that arc. We open every tilt-and-turn window fully during a measure to check it.
What if new-build windows have shallow reveals?
Shallow reveals are common in new builds because windows are often set towards the inside face of the wall, leaving only a small plaster return around the frame. A shallow reveal may not be deep enough to hold a roller, brackets and handle clearance, so the blind usually goes outside the recess or on the frame instead.
A face-fixed blind, mounted on the wall above the opening and overlapping each side, is often the neatest answer. It also cuts light gaps at the edges, which matters for bedrooms. If you want a blackout effect, fitting outside the recess with a generous overlap does more than any fabric change. Our guide to measuring for roller blinds explains how much overlap to allow.
Deep window boards (internal sills) matter too. A blind fitted outside the recess must stop just above the board or clear its projection, so measure both.
Large glazed doors and floor-to-ceiling windows, common in new flats, have their own rules. Our page on roller blinds for French and patio doors covers handle clearance, door swing and wide spans.
What can blinds be fixed into in a new-build home?
New-build blind fixings usually go into one of three materials: plasterboard, a steel or concrete lintel above the window, or the uPVC frame itself. Each needs a different approach, and the wrong fixing is a common reason blinds pull away from new walls. Knowing what is behind the plaster comes first.
Plasterboard. Many new homes are dry-lined, with plasterboard stuck to blockwork on adhesive dabs or fixed to a timber or metal frame. Standard plugs in plasterboard alone will not hold a blind that is pulled up and down every day. The fixing has to reach the solid wall behind, hit a stud or batten, or use a proper cavity fixing rated for the load.
Steel lintels. Directly above most window openings sits a lintel, and in brick and block houses this is often steel. It can be only a few millimetres behind the plaster. A fitter needs the right drill bit and fixings for metal, and should expect it rather than discovering it halfway through a hole. Timber-frame houses are different again, with timber members around the opening.
uPVC frames. Screwing into a window frame can be fine with the right short screws, but it is permanent and may matter for the window manufacturer’s guarantee. Check your paperwork before agreeing to any frame fixings, particularly in the first couple of years.
Cables and pipes do not always run where you expect, so check before drilling. Our measuring and fitting service covers these checks.
Will fitting blinds affect a new-build warranty?
New-build warranties generally cover defects in how the home was built, not items you add afterwards. Under NHBC’s Buildmark, the builder is responsible for putting right defects in the first two years, followed by insurance cover to year ten. Alterations you make after completion are excluded, so fixings you add are your responsibility.
That does not mean blinds are a problem. Screwing brackets into a wall is routine. The points to watch are narrower:
- Damage caused by a fitting, such as a cracked reveal or a drilled cable, will not be the builder’s to fix.
- Window frames may carry their own guarantee with conditions about drilling. Check it.
- If you have an outstanding snag on a window or reveal, get it fixed before a blind goes up, so nobody can blame the blind.
Other warranty providers work on similar lines, but the terms differ. Read your own policy, or the NHBC summary of Buildmark cover if that is your provider, and the homeowner guide your developer gave you at handover. If in doubt, ask the developer’s customer care team before drilling into window frames.
When should you book blinds for a new-build home?
The best time to book blinds for a new-build home is straight after handover, once you have the keys and have done a first snagging walk-round. That way the measurements reflect the finished windows, any reveal or window defects are logged first, and the blinds can go up soon after you move in.
A sensible order runs like this:
- Handover and snag list. Walk every room and note problems with windows, reveals, sills and plaster. Report them to the developer.
- Measure. Book a measuring visit as early as you can after completion. Windows are fixed in position by then, and measurements taken on the finished opening are reliable.
- Fix window snags first. If a window is being adjusted, re-sealed or replaced, wait for that before fitting.
- Fit. Blinds go up once the reveals are finished and any snag work around the windows is complete.
New homes dry out over their first months, and small shrinkage cracks in plaster are common. A crack along a reveal is worth reporting before a bracket goes near it.
Can you measure for blinds before moving in?
You can measure for blinds before moving in, provided the windows are installed and the reveals are plastered. The most useful time is after completion but before furniture arrives, when every window is easy to reach. Measuring from the developer’s plans alone is risky, because finished openings rarely match drawings to the millimetre.
Some developers allow buyers a pre-completion visit to measure up. Others only allow access once the sale completes. Ask your sales adviser what is possible. If you do get access early, take these measurements for each window:
- Recess width at the top, middle and bottom, and use the smallest for a recess fit.
- Recess height on the left, centre and right.
- Reveal depth from the frame face to the room.
- Handle projection from the frame, with the handle locked.
- Position and length of the trickle vent.
- For tilt-and-turn windows, the height the sash needs to clear when fully opened.
Label each window by room so nothing is mixed up later.
Common mistakes with blinds in new-build homes
The most common mistakes with blinds in new-build homes come from treating every window the same. New developments mix fixed panes, side-hung casements, tilt-and-turn sashes and glazed doors, often in one room. Each type needs its own fitting decision, and a single approach for the whole house nearly always causes a clash somewhere.
- Covering the trickle vent with a bracket. The vent must stay open and usable.
- Forgetting handle depth. The blind gets caught on the handle every time it comes down.
- Recess fitting a tilt-and-turn window with no headroom. The sash hits the roll when opened.
- Using plasterboard plugs only. The blind loosens within weeks of daily use.
- Measuring from plans. Drawings rarely match the finished opening.
- Fitting over an unresolved snag. It muddies who is responsible for the repair.
Where can you get blinds fitted in new-build homes in East London and Essex?
New-build blinds in East London and Essex are best measured in person, because developments across the area use a wide mix of window systems, lintels and wall build-ups. A home visit lets someone open every window, find the vents and check what the brackets will fix into before a single blind is made.
The riverside and regeneration areas of East London have a lot of new flats with tall windows, Juliet balconies and tilt-and-turn sashes. New housing estates across Essex tend to mix casements, French doors and bi-folds. North Kent has plenty of recent development too. HD Blinds offers a free, no-obligation home measure across London, Essex and North Kent, with fabric samples brought to you and a written quote. See the areas we cover to check your postcode.
Key takeaways
- Plan bracket positions around trickle vents so they stay open and easy to reach.
- Measure handle projection and compare it with the reveal depth before choosing recess or outside fit.
- Tilt-and-turn windows need a blind above the sash or fixed to it.
- Know what is behind the plaster: plasterboard, steel lintel, timber or blockwork.
- Read your warranty and window guarantee, and fix snags before fitting.
- Book the measure soon after handover, not from the developer’s plans.
Frequently asked questions
Is it okay for a roller blind to hang in front of a trickle vent?
Yes, a roller blind can hang in front of a trickle vent, as long as the vent itself is not covered by brackets or a headrail and the slider stays easy to reach. Fitting the blind above the frame, or on the frame below the vent, keeps air moving while the blind is down.
Do I need permission from the developer to fit blinds?
Freehold owners usually do not need developer permission to fit internal blinds. Leaseholders in new flats should check the lease, as some restrict changes visible from outside. Either way, read your warranty and window guarantee before drilling into frames, and report any window snags before fitting.
Can blinds be fitted to tilt-and-turn windows without stopping them opening?
Blinds can be fitted to tilt-and-turn windows without blocking them. Either fit the blind above the frame so the sash opens beneath the rolled-up blind, or fit an exact-fit blind to the sash so it moves with the window. A recess fit only works when there is plenty of headroom above the sash.
How soon after moving into a new build can blinds be fitted?
Blinds can be fitted as soon as the windows and reveals are finished and any window snags are resolved. Most people book a measure straight after handover. If you are planning to decorate or a window is due to be adjusted, fit afterwards so the blind is not taken down again.
Why do blinds come loose in new-build homes?
Blinds come loose in new-build homes mainly because they were fixed into plasterboard with plugs meant for solid walls. Daily pulling works the fixings free. The fix is to reach the blockwork or a stud behind, fix into the lintel with suitable fixings, or use rated cavity fixings.
