Window & Door Fitting Quotes: What’s Included, Measurements, and Common Extras

Window and door fitting quote checklist for the UK. Learn what’s included, why surveys matter, common extras like disposal and making good, and red flags.

Window and door fitting quotes can be hard to compare because “the same job” often isn’t the same at all. One quote may include a full survey, disposal of old frames, making good around reveals, and upgraded glazing. Another may be fit-only, assume standard specs, and add costs later once measurements or access issues are confirmed.

This guide explains what a professional window and door fitting quote should include in the UK, why measurements matter so much, and the common extras you should clarify before you commit. Browse local window and door fitters near you to compare options before requesting quotes.

What a Window & Door Quote Should Include (Minimum)

A reliable quote should clearly confirm:

• What’s being supplied and/or installed (windows, doors, both)

• Survey/measurements included (or excluded)

• Product specification (frame type, glazing spec, hardware)

• Removal and disposal of old units included or extra

• Making good (internal/external) included or excluded

• Timescales (survey date, lead time, install dates)

• VAT clarity

• Payment terms (deposit/stage/final payment)

• How changes and extras are approved

For this service, spec + survey + making good is where quotes usually differ.

1) Survey and Measurements: Included or Extra?

Accurate measuring is essential — and it’s one of the biggest reasons quotes change.

A quote should state:

• whether a survey/measure visit is included

• whether the initial price is provisional pending survey

• what happens if measurements change the spec or cost

• whether survey fees are charged and refundable if you proceed

Tip: If the quote is given from photos only, treat it as a starting estimate until a proper survey confirms sizes and condition.

2) Supply & Fit vs Fit-Only (Big Price Difference)

Some providers quote for:

• supply + installation

• installation only (you supply products)

Confirm:

• whether the quoted price includes the units

• whether you’re choosing the products

• who is responsible if supplied products don’t fit or have faults

• whether materials like trims, fixings, and sealants are included

Fit-only can be cheaper — but it can also create responsibility gaps if the products aren’t correct.

3) Specification: Frame Type, Glazing, and Hardware

This is where “similar” quotes become non-comparable.

A professional quote should specify:

• frame material (uPVC, aluminium, timber, composite)

• glazing type (double/triple, acoustic, laminated, low-E)

• colour/finish and handles/hardware

• security features (locks, hinge types)

• trickle vents (if included)

• whether the quote includes upgrades or standard spec

If the quote says “new windows installed” with no spec, ask for the product details in writing.

4) Removal, Disposal, and Skip Costs

Old frames, glass, and rubble need disposal, but it’s not always included.

Confirm:

• whether removal of old windows/doors is included

• whether disposal is included

• whether skip hire is needed (and included)

• whether there are extra charges for heavy or awkward removals

Disposal is a classic source of unexpected extra charges.

5) Making Good: Internal and External Finishing

A quote might cover fitting only, but leave the “finishing” to you.

Confirm whether the quote includes:

• internal trim and neat finishing

• plaster repairs around reveals

• external sealant and weatherproofing

• replacing or repairing damaged sills/frames

• paint touch-ups (rarely included unless stated)

If you want the job to look finished, making good matters as much as the fitting itself.

6) Access, Parking, and Building Constraints

Costs can rise if access is difficult or if extra time is needed.

Common access factors:

• upper floors without easy access

• restricted parking/loading

• narrow staircases or tight hallways

• communal areas and booking lift access

• working hours restrictions (commercial sites)

Best practice: mention any constraints before quoting and share photos where helpful.

7) Lead Times, Scheduling, and Installation Duration

Window and door work often involves manufacturing lead times.

A good quote should clarify:

• whether products are in stock or made-to-order

• estimated lead time after survey and deposit

• expected installation duration

• what happens if delivery is delayed

This helps you plan, especially if security or weather exposure is a concern.

8) Fixed Quote vs Estimate

A quote may be fixed after survey, but estimated before.

Ask in writing:

• Is this provisional until survey?

• When does the price become fixed?

• What could increase the cost (repairs, access, extras)?

• How are changes approved before continuing?

Agree the “pause, price, approve, proceed” approach for any extras.

9) Payment Terms: What’s Normal?

For supply-and-fit, deposits are common because products are ordered to size.

Good practice often looks like:

• deposit after survey confirmation

• staged payment for larger projects

• final payment after installation is completed and checked

Red flags:

• unclear terms

• pressure to pay immediately

• full payment upfront without clear paperwork

Always keep documentation and ask for invoices/receipts.

10) Red Flags in Window & Door Quotes

Be cautious if you see:

• no mention of survey/measurements

• no product spec (frame/glazing/hardware)

• unclear disposal and making good terms

• very low prices with vague inclusions

• pressure to sign quickly

• refusal to confirm details in writing

If the quote is unclear, ask for clarification before committing — this service is too expensive to guess.

FAQ — Window & Door Fitting Quotes (UK)

1) Why do window and door fitting quotes vary so much?
Differences in survey/measurements, product specification (frame and glazing), disposal, making good, and access constraints can change pricing significantly.

2) Is a survey included in most quotes?
Many providers include a survey, but some treat early pricing as provisional. Always confirm whether the quote is subject to survey.

3) What does “making good” usually include?
It varies. It can include trims and sealant, but plaster repairs and external finishing may be excluded unless stated. Confirm it in writing.

4) Are removal and disposal included in fitting quotes?
Not always. Ask whether old frames/glass removal and disposal are included, and whether skip hire is needed.

5) Is it better to choose supply-and-fit or fit-only?
Supply-and-fit can be simpler because one provider is responsible for product and installation. Fit-only can be cheaper but can create responsibility issues if products don’t fit or arrive damaged.

6) When does the quote become fixed?
Often after survey and final specification confirmation. Ask when pricing becomes fixed and what could increase the cost before that.
