| Job | Low | Average | High | Duration |
|---|---|---|---|---|
| Single Casement Window (uPVC) | £385 | £555 | £725 | 2-3 hours per window |
| Supply and fit a standard double-glazed window with one opening panel. This is the most common window type in UK homes — it can open from the top or from the side. All modern replacements are double-glazed with good energy ratings as standard. Price includes removing and disposing of the old window, fitting new trim around the inside, and sealing the outside. What affects the price
| ||||
| Double Casement Window (uPVC) | £485 | £680 | £870 | 2-4 hours |
| Supply and fit a wider double-glazed window with two opening panels side by side. Common in living rooms and bedrooms where you need a bigger window. Both panels open independently, and on first floors one usually needs to open wide enough to escape in a fire. Includes new trim and all sealing. What affects the price
| ||||
| Bay Window (3-Panel, uPVC) | £1,160 | £1,935 | £2,905 | 1 day |
| Supply and fit a three-panel double-glazed bay window. Bay windows stick out from the wall, usually with a fixed centre pane and two opening side panels at an angle. Price typically includes structural support, the small roof over the bay, and all internal finishing. This is a bigger job than a flat window because of the angles and weatherproofing involved. What affects the price
| ||||
| Sash Window Replacement (uPVC) | £580 | £870 | £1,160 | 3-4 hours |
| Supply and fit a plastic (uPVC) sliding sash window with double glazing, designed to look like traditional Victorian or Edwardian windows but with much less maintenance. The panels slide up and down like old-style sash windows. A good option if you want the classic look without repainting every few years. Note: if your home is in a conservation area, you may need to use timber instead — check with your council first. What affects the price
| ||||
| Sash Window Replacement (Timber) | £970 | £1,550 | £2,420 | 4-6 hours |
| Supply and fit a real wooden sliding sash window with double glazing. Timber sash windows are often required in conservation areas or listed buildings where plastic windows are not allowed. They are made to measure and arrive pre-painted. Hardwood options last longer but cost more than softwood. Expect to repaint them every 5-8 years. What affects the price
| ||||
| French Doors (uPVC Pair) | £775 | £1,115 | £1,450 | Half day |
| Supply and fit a pair of double-glazed French doors that open outward (or inward) from the centre. Popular for opening onto a garden or patio. Price includes a new frame, sill, internal trim, multi-point locks, and all handles. Available in white or coloured finishes, though non-white options cost more. What affects the price
| ||||
| Patio / Sliding Doors (uPVC) | £870 | £1,405 | £1,935 | Half day |
| Supply and fit double-glazed sliding patio doors. One panel slides behind the other, making them ideal where you do not have room for doors to swing open. Available in 2, 3, or 4 panel sizes. Wider openings cost more because of the bigger glass panels and heavier frames. Includes secure locking, new sill, and internal finishing. What affects the price
| ||||
| Bi-Fold Doors (3-Panel, Aluminium) | £2,420 | £3,630 | £4,840 | 1 day |
| Supply and fit 3-panel aluminium bi-fold doors with double glazing. These fold open like a concertina to create a wide opening between your home and garden. Aluminium frames are slimmer than plastic ones, giving you more glass and a modern look. Price includes the structural beam above the opening (if needed), threshold, secure locking, and all finishing. Plastic bi-folds are 20-30% cheaper but have thicker frames. What affects the price
| ||||
| Front Door Replacement (Composite) | £775 | £1,115 | £1,450 | 3-4 hours |
| Supply and fit a composite front door with a new frame, multi-point locks, and all handles. Composite doors have a solid core with a tough outer skin, making them more secure, better insulated, and longer-lasting than standard plastic doors. Available in a wide range of styles, colours, and glass designs. Look for doors with a security rating approved by police and insurers (often called 'Secured by Design'). What affects the price
| ||||
| Full House Window Replacement (3-Bed, 8 Windows) | £3,390 | £4,840 | £6,290 | 2-3 days |
| Supply and fit all windows in a typical 3-bedroom house (approximately 8 standard double-glazed windows). Price includes removing all old windows, fitting new trim, sealing, and a FENSA certificate (this proves the work meets building regulations — you will need it if you sell the house). Beware of pressure-selling window companies that quote eight to twelve thousand pounds for this same work — the realistic market rate is three and a half to six and a half thousand. Common high-pressure tactics include fake 'manager discounts' on the spot, limited-time pricing, and claiming you qualify for government grants you may not be eligible for. Always get at least three quotes from local FENSA-registered installers and never sign on the first visit. What affects the price
| ||||
| Glass Replacement (Single Sealed Unit) | £75 | £130 | £195 | 30-60 minutes |
| Replace just the glass panel inside an existing window frame — the frame stays in place. This is usually needed when you can see condensation or misting trapped between the two panes (meaning the seal has failed) or when the glass is cracked. Much cheaper than replacing the whole window. What affects the price
| ||||
| Secondary Glazing (Per Window) | £195 | £290 | £385 | 1-2 hours |
| Fit an extra panel of glass or clear plastic on the inside of an existing window to improve insulation and reduce noise. This does not replace the original window, which makes it popular in listed buildings or conservation areas where you are not allowed to change the windows. The extra panel can be fixed, sliding, or hinged so you can still open it. What affects the price
| ||||
| Roof Window / Skylight (Velux-Style) | £485 | £825 | £1,160 | Half day |
| Supply and fit a roof window (commonly called a Velux) including the weatherproof surround. The fitter cuts a hole in the roof, removes tiles, and fits the window between the rafters. Price assumes a straightforward installation without any structural changes needed. Electric or solar-powered versions that open by remote cost more but are worth it if the window is hard to reach. What affects the price
| ||||
| Window Repair (Hinges, Locks, Handles) | £50 | £95 | £145 | 30-60 minutes |
| Fix a window that will not close properly, lock securely, or has a broken handle. Common repairs include replacing hinges, fitting new handles, fixing or replacing the locking mechanism, and re-aligning panels that have dropped. Much cheaper than a full window replacement and usually done in a single visit. What affects the price

Step by step
What's Involved in Hiring a Window Fitting
Replacing windows involves choosing the right products, finding a trustworthy installer, and making sure the work complies with building regulations.
Decide what you need replacing
Work out which windows need replacing and why — failed sealed units (misting between panes), draughty frames, damaged mechanisms, or a general upgrade for energy efficiency. Sometimes only the glass units need replacing rather than the whole window, which is significantly cheaper.
Get quotes from FENSA-registered installers
Get at least three quotes from local installers registered with FENSA or CERTASS. These schemes mean the installer can self-certify that the work meets building regulations, saving you the cost and hassle of a separate council inspection. Be very cautious of large national companies that use high-pressure sales tactics and inflated prices.
Choose your window style and material
uPVC is the most popular and affordable option. Aluminium offers slimmer frames and a more contemporary look. Timber suits period properties but needs regular maintenance. For properties in conservation areas or listed buildings, there may be restrictions on what materials and styles you can use — check with your local planning department.
Survey and manufacture
The installer will visit to take precise measurements of every window opening. The windows are then manufactured to order, which typically takes 4-6 weeks. Any structural work needed (such as widening an opening for bi-fold doors) should be discussed at this stage.
Installation day
Each standard window takes 2-3 hours to fit. The fitter removes the old window and frame, checks the opening, fits the new window, insulates around it with expanding foam, and finishes with internal trim and external sealant. A full house of 8-10 windows typically takes 2-3 days.
Building regulations certificate and aftercare
Your installer should provide a FENSA or CERTASS certificate within 8 weeks confirming the work meets building regulations. Keep this safe — you will need it when selling your property. Most windows come with a 10-year guarantee covering the frames and sealed units. Report any issues with misting, draughts, or mechanisms promptly.

Local insights
What Affects Window Fitter Costs in Torfaen?
Wales has a distinctive mix of housing, from Victorian and Edwardian terraces in the south to stone-built cottages and rural properties across the rest of the country. Torfaen has a range of property types and ages that can affect the scope and cost of work, and the wider area around Swansea and the Valleys includes many older properties that present challenges for window fitter work. With a population of null, Torfaen is a area where window fitter costs are close to the national average. Stone walls, exposed locations, and older infrastructure all tend to push costs toward the higher end — double casement window (upvc) here averages around £680.
Wales sits below the national average for trade costs. Labour rates in Torfaen are typically 3% below the UK average. In Torfaen, local demand for window fitter services varies depending on the mix of residential and commercial properties in the area. While this makes window fitter work more affordable, there can be fewer qualified professionals in rural areas compared to English cities, which can mean longer waiting times. With fewer tradespeople based locally, you may find slightly less choice, and it is worth booking ahead for larger jobs. Always get at least three quotes.
Properties in Torfaen can present specific challenges that affect window fitter costs. Stone-built and older Welsh terraces often have thick walls that make work more difficult and expensive. Properties in exposed or rural locations may face harsher weather conditions that influence timing and approach. A typical single casement window (upvc) in Torfaen costs around £555, while for larger jobs expect to pay £3,390 to £6,290 for full house window replacement (3-bed, 8 windows). As a area that is close to the national average, Torfaen offers decent value for window fitter work overall.
When getting quotes in Torfaen, aim for at least three from different qualified professionals. Ask each one to visit and assess the work rather than quoting over the phone. A good window fitter will check existing conditions, identify complications, and provide a detailed cost breakdown. With fewer tradespeople based locally, you may find slightly less choice, and it is worth booking ahead for larger jobs. Be wary of quotes that seem significantly cheaper — they may be cutting corners on materials or quality. Always check qualifications, insurance and recent reviews.
Depending on the work involved, you may also need painting & decorating (£195–£630), carpentry (£70–£195), or handyman (£40–£115) in Torfaen.
