Homeowners: Shutter Brief per Window

Client shutter brief preparation guide
A complete shutter brief gives your supplier exact measurements for every window, states the window type and shape, includes labelled photographs, and sets out your preferred material, finish, panel layout and louvre size. Add site access notes, a budget band, and your preferred installation window. Any professional maker will ask for these details before producing an accurate quotation, so preparing them upfront saves time on both sides.
TL;DR:
- Precise measurements, clear photographs, and detailed design preferences improve quote accuracy and reduce installation issues, especially on complex or non-standard windows.
- Budget ranges are preferable to fixed figures, and early communication of installation schedule helps align manufacturing and scheduling timelines.
- Professional surveys are recommended for irregular, bay, arched, or historic windows to ensure proper fitting and avoid costly errors.
- Suppliers should provide written guarantees, show past work on similar window shapes, and verify their in-house or trusted survey process before commitment.
- Attention to sightline matching and handle or sill obstruction photos can prevent common post-installation issues and ensure a seamless final result.

What should a client shutter brief preparation guide include?
A shutter brief is simply a written specification. Suppliers use it to scope your project before anyone picks up a tape measure professionally, and the more precise yours is, the closer your first quote will land to your final invoice.
Here’s what a well-built brief covers, window by window:
- Window reference – label each window (Window 1, Window 2, and so on) so nothing gets muddled if you have several rooms in one enquiry.
- Measurements – width, height, depth, and a diagonal check, noted as either recess (inside the window reveal) or face-fit (covering the whole frame).
- Window type – standard rectangular, bay, arched, angled, skylight, bi-fold, or conservatory.
- Photographs – at least one wide shot and one close-up, clearly labelled to match the window reference.
- Design preferences – material, finish or colour, louvre size, mid-rail or divide height, and frame style.
- Access and installation notes – anything that might affect fitting, such as radiators, deep sills, or restricted parking.
- Budget band and timing – a realistic range rather than one fixed number, plus your preferred installation window.
Pro Tip: Send one email per property rather than one per window. Suppliers process multi-window enquiries faster when everything sits in a single, well-organised message.
A short template does the job well. Something like: “Hi, I’d like a quote for shutters in three rooms. Window 1 (living room bay): width 1,820mm, height 1,340mm, depth 120mm, recess fit. Photos attached. Preference for hardwood in a soft white finish, standard louvre size. Budget around £1,200 to £1,800 per window. Ideally installed within eight weeks. Happy to discuss a survey.” Adapt that structure for each window and you’ve given a supplier everything needed to respond with a proper quote rather than a vague estimate.
How do I measure my windows and take useful photos?

Getting the numbers right matters more than almost anything else in the brief. Most fitting problems trace back to a measurement taken once, in a hurry, without checking the window is actually square.
Follow this sequence for a standard window:
- Decide recess or face-fit first. Recess mounting sits the shutter inside the window reveal, so you’ll need reveal depth as well as width and height. Face-fit sits over the frame and skips the depth measurement, though you still record it if you’re unsure which method suits the room.
- Measure width in three places – top, middle, and bottom of the reveal or frame – and record the smallest figure.
- Measure height in three places – left, middle, and right – and again take the smallest.
- Check the diagonals. Measure corner to corner both ways. If the two figures differ by more than a few millimetres, the window is out of square, and your supplier needs to know that before manufacturing anything, since diagonal checks confirm whether a window frame is square before it goes into production.
Complex shapes need their own approach:
- Arched windows – record the span (width at the base) and the rise (height from base to the highest point of the curve).
- Angled bay windows – measure each facet separately, including its own width, height and angle where possible.
- Triangular skylights – note the base width and the vertical height to the apex.
- Anything historic, oddly proportioned, or genuinely unclear – book a professional survey rather than guess.
For photographs, take a wide shot showing the whole window in context, a close-up of the reveal or frame edge, and a close-up of any handle or catch. Label each image with the matching window reference so nothing gets mismatched once it lands in a supplier’s inbox, since labelled photos from multiple angles help suppliers assess obstructions and reveal depth without needing to visit first.
What design choices affect price and manufacturing?
Every stylistic decision you make changes either the cost, the manufacturing complexity, or both. Stating your preferences clearly means the quotes you receive are actually comparable.
Material is the first fork in the road. MDF with a polypropylene coating handles moisture well, making it a sensible choice for bathrooms, kitchens, and conservatories, while sitting at a lower price point than hardwood. Premium hardwood, by contrast, gives a richer grain and a longer-term finish that suits living rooms, hallways, and period properties where appearance carries more weight than budget.
Louvre size shapes both light control and how the shutter looks when closed, since larger louvres open up sightlines while smaller louvres give finer control over light. Bedrooms often suit slightly larger louvres for a bolder look, living rooms sit comfortably in the middle, and kitchens benefit from smaller louvres where precise light adjustment matters near worktops.
State your panel layout and opening preference too. Suppliers will usually propose the most practical configuration for the width you’re covering, but you should still say which side you’d like the panels to open from and how many panels you’re expecting, since panel configuration depends on window width and stated opening preference. If a mid-rail is relevant, note where you’d like it positioned, since mid rails let the top and bottom louvres operate independently and are common on taller panels.
- Note your frame preference: L frame (recess) or Z frame (face fit with an architrave look).
- Provide a paint or stain reference if you have one, or ask the supplier for colour matching.
Pro Tip: If you’re shuttering several windows in the same room, ask your supplier to match louvre sightlines across them. Mismatched louvre heights on adjacent windows is one of the most common complaints fitters hear after the fact.
What site access details does the supplier need?
Installation logistics get overlooked more often than they should, and they can affect both price and scheduling once a fitter is on site.
- Access – note parking availability, distance from the road to the front door, and whether there are stairs to navigate with panels.
- Room occupancy – say whether the room needs to stay usable during fitting, which affects how the visit is scheduled.
- Obstructions – flag window handles, radiators, vents, deep sills, or decorative coving that might interfere with the frame.
- Permissions – mention landlord consent, listed building status, or restricted conservatory roof access if any apply.
- Panel size – very large or heavy panels sometimes need two installers or additional equipment, so flagging this early lets the supplier plan the visit properly.
How should I set my budget and timeline expectations?
Give a budget band rather than a single number. A range like £150 to £220 per square metre tells a supplier far more than a flat figure, because it signals whether you’re prioritising price or finish, and lets them suggest the right material without guessing.
Bespoke shutters typically take several weeks to manufacture once measurements are confirmed, so state your preferred installation window early rather than assuming a supplier can turn things around overnight. If budget is tight, there are trade-offs worth raising directly: MDF instead of hardwood, a simpler frame style, or phasing the project room by room rather than shuttering the whole house at once.
- Ask for an itemised quote, not a single lump sum.
- Confirm whether survey, delivery, and installation are included in the price.
- Check what the product and workmanship guarantee actually covers before you sign anything.
Diagonal checks matter more than most homeowners realise. Even a small discrepancy between the two diagonal measurements on a window can mean the frame is out of square, and that single detail changes how the shutter needs to be manufactured to fit properly.
What happens after you send your brief to a supplier?
Once your brief lands with a supplier, expect a short back-and-forth before anything is booked in.
- Review and clarification – the supplier checks your measurements and photos, and may ask follow-up questions, particularly on complex or non-standard windows.
- In-home survey – for anything beyond a simple rectangular window, a professional survey is strongly recommended, since DIY measuring suits straightforward windows while complex shapes benefit from a professional visit. Clear access, remove existing blinds or curtains beforehand, and make sure someone is home to answer questions on site.
- Quote confirmation – read it carefully, confirm your chosen options in writing, and check deposit terms before paying anything.
- Installation day – most single-room jobs take a few hours. Before the fitter leaves, check that louvres open and close smoothly, panels sit flush, and nothing rattles or catches on the frame.
How do I check a supplier’s certifications and quality standards before committing?
Not every quote you receive will come from a supplier who can back up their claims. Before commissioning anything, it’s worth running through a short verification checklist.
Ask how long the company has been trading and whether they manufacture in-house or outsource production, since that affects both quality control and lead times. Request to see examples of past work on windows similar to yours, particularly if you have an arched, bay, or angled bay shape, since these demand more precise engineering than a standard rectangle.
Confirm what guarantees are offered in writing, covering both the product itself and the standard of workmanship on installation. A supplier confident in their manufacturing should have no hesitation putting this in your quote document rather than leaving it as a verbal promise.
Check whether the company carries out its own in-home surveys with trained staff, rather than subcontracting measurement to a third party who may not understand shutter-specific tolerances. Ask what happens if a panel arrives faulty or doesn’t fit, since the answer tells you a great deal about how the business handles problems after the sale has gone through.
Finally, look for verified customer reviews rather than testimonials curated only for the company’s own website. Genuine feedback tends to mention specifics, fitting time, communication, how obstructions were handled, rather than vague praise, and that specificity is usually a good sign you’re dealing with an established, accountable business.
What maintenance and warranty terms should you expect after installation?
Shutters are a long-term fixture, so it’s worth understanding upkeep and cover before the fitter has even left the property.
Day-to-day maintenance is minimal. A soft cloth or duster on the louvres every few weeks keeps them looking sharp, and an occasional wipe with a mild, non-abrasive cleaner handles most marks. MDF with a polypropylene coating tolerates damp environments well, making it low-maintenance in bathrooms and kitchens, while hardwood benefits from being kept away from direct, prolonged moisture exposure to protect the finish over time.
On warranty terms, clarify two separate things before you commission: the product guarantee, which covers materials and manufacturing defects, and the workmanship guarantee, which covers the quality of the installation itself. These are often different lengths, so ask your supplier to state both clearly rather than assuming one covers everything.
Keep your original brief, quote, and any written confirmation of your chosen options somewhere accessible. If a hinge needs adjusting or a louvre pin works loose years down the line, having the original specification on hand makes any warranty claim considerably faster to resolve, since the supplier can match the part exactly rather than trying to reverse-engineer what was fitted.
Ken’s perspective: two things clients almost always forget
After 25-plus years watching briefs land on a supplier’s desk, the pattern is consistent: two details get missed more than any others. First, sightline matching across adjacent windows in the same room, which causes visible inconsistency once shutters are fitted. Second, handle and sill photographs, which are easy to skip but often reveal the one obstruction that changes a whole installation plan. A solid product and workmanship guarantee exists precisely because these details matter, and a careful brief means you’ll rarely need to call on it.

FAQ
What measurements does a shutter brief need?
Width, height, and diagonal measurements for every window, plus reveal depth if you’re planning a recess fit rather than a face-fit installation.
How many photos should I include per window?
Two to three: a wide shot of the whole window, a close-up of the reveal or frame, and a close-up of the handle or catch, all clearly labelled.
Do I need a professional survey for a standard rectangular window?
Not always. Simple rectangular windows can often be measured accurately at home, but arched, angled, bay, or historic windows benefit from a professional in-home survey like the one Shutter World provides.
Should I give a supplier an exact budget or a range?
A range works better than a single figure, since it tells the supplier whether finish or price matters more to you, letting them recommend suitable materials without guesswork.
What’s the difference between an L frame and a Z frame?
An L frame sits inside the window reveal for a recessed look, while a Z frame fits over the face of the window with an architrave-style finish.
