What £450 fully fitted actually buys
That is a real small to medium window, A-rated, with a warm edge spacer, argon fill and multi point locking, fitted by our own team. It includes taking the old window out, disposing of it, sealing and making good the reveal, and the certificate at the end.
It is worth stating what it does not include, because that is where quotes diverge. It does not include a bay, which is a structural job, and it does not include a sliding sash or a flush profile, which are different products with their own starting prices.
| Window | From price, fully fitted |
|---|---|
| uPVC casement | £450 |
| Flush casement | £520 |
| Tilt and turn | £560 |
| Triple glazed casement | £610 |
| Sliding sash | £780 |
| Aluminium | £890 |
| Bay, three facet | £1,850 |
Why per house is a band and not a number
A house is not a multiple of one window. Bedrooms need escape sized openers, bathrooms need obscure glass, a front bay is a structural operation and a landing window may be fixed and cheap. Add those together and two identical looking semis on the same street can differ by a four figure sum.
The useful thing to ask for is one fixed written figure for the whole job after a measured survey, itemised so you can see which openings carry the cost. We will happily strip an opener out of the specification if you never use it.
- Number of openings, and how many of them actually need to open
- Whether a bay is included, which is priced as a structural job
- Glass upgrades such as acoustic laminate, solar control or obscure
- Colour, since a foil or a powder coat adds to every unit
- Access at the rear, scaffolding, and whether there is parking
Where to spend and where to hold back
Spend on the front elevation, because it is seen from the street and it is where a flush profile or a correct bar layout earns its money. Spend on glass in rooms with a specific problem, a road, a west facing glare, a bathroom overlooked by a neighbour.
Hold back on opening every light out of habit, on triple glazing in a sheltered mid terrace, and on decorative details at the rear that nobody will ever look at.
Get your actual number, not a range
A free measured survey gives you one fixed written figure with every opening itemised, so you can see where the money is going.
