How Much Does Double Glazing Cost In Exeter?

Double glazing costs in Exeter vary quite a bit depending on the size of your property, the type of windows you choose and what’s already there. Based on jobs we’ve carried out across the city, a typical full-house replacement for a 3-bedroom semi runs somewhere between £3,500 and £7,000 - though you’ll find quotes above and below that range depending on who you ask and what’s included.

This guide breaks down what drives the cost and what to look out for when you’re getting quotes. If you’re after a figure specific to your property, the quickest way is a free survey from our team - we’ll measure up and give you a written price before you commit to anything.

What Affects The Cost Of Double Glazing In Exeter?

Number and size of windows

The most obvious factor. A one-bedroom flat might need four or five windows; a larger detached could be twenty or more. Size matters too - a standard casement window costs considerably less to supply and fit than a large bay or a picture window.

Most installers price per window, so the total quickly adds up on a bigger property. Don’t assume a quote from a house two doors down reflects what yours will cost - window counts and sizes vary more than people expect.

Frame material

uPVC is the most popular choice in Exeter and generally the most affordable. Aluminium costs more but gives slimmer frames and a more modern look, which suits some properties better. Timber frames are the most expensive option and require more maintenance, but are sometimes the only acceptable choice for listed buildings or properties in conservation areas.

Glass specification

Standard A-rated double glazing is fine for most Exeter homes. Step up to triple glazing or specialist acoustic glass and the price increases. Acoustic glazing is worth considering if you’re on a busy road - the A379 and Topsham Road get noisy enough that it makes a real difference. The Energy Saving Trust’s guidance on windows and doors explains how energy ratings work and what to look for when comparing quotes.

Existing frame condition and installation complexity

If your current window reveals are in poor condition, or if the openings aren’t square, that adds time and cost. Older properties in Heavitree, St Thomas and around the Cowley Bridge Road area sometimes have irregular reveals - particularly 1930s and pre-war properties where the original building wasn’t always precise.

Difficult access also adds to the price. Upper floor windows on a three-storey property will take longer to fit than ground-floor ones.

Typical Double Glazing Prices In Exeter

These are rough guide prices based on standard uPVC double glazing. Exact prices depend on your specific windows - treat these as a starting point, not a firm quote.

Window type	Typical supply and fit cost
Standard casement window	£400 - £700
Larger picture window	£600 - £1,000
Bay window	£1,200 - £2,500
Sash window	£700 - £1,200
Tilt-and-turn window	£500 - £900

For a standard 3-bed semi with 8-10 windows, expect the total to land somewhere between £3,500 and £6,500 for uPVC in white. Coloured frames, aluminium or timber will push that higher.

What’s Included In A Double Glazing Quote?

A properly written quote should include:

• Supply of frames and glazing units
• Removal and disposal of old windows
• Installation labour
• Making good around the reveals internally (usually with white trim)
• FENSA certificate on completion

Watch out for quotes that look cheap but don’t include disposal of old units, or that have a separate charge for the certification. A lower headline price can end up costing more once extras are added.

Is It Worth Getting Multiple Quotes?

Yes - but keep a few things in mind. The cheapest quote isn’t always the best value. We’d suggest getting two or three quotes and comparing what’s actually included. Check whether each company is FENSA registered using the FENSA approved installer search and whether they carry public liability insurance. Which? has a useful double glazing buying guide that covers the questions worth asking when comparing installers.

Also worth checking: do they offer a product warranty separate from the installation guarantee? The frames and sealed units should come with a manufacturer warranty of at least ten years. If a company only offers a five-year all-in guarantee, it’s worth asking why.

Double Glazing For Listed Buildings In Exeter

If your property is listed or sits within one of Exeter’s conservation areas - which includes Topsham, Cathedral Close and parts of the city centre - you can’t simply swap out the original windows for double glazed units. Secondary glazing is the standard approved route in these cases, and it’s worth knowing upfront so you don’t get halfway through planning work on a budget based on full replacement prices.

Secondary glazing is fitted on the room side of the existing window and is considerably cheaper than full replacement - typically £300 to £600 per window depending on the system. It doesn’t give quite the same thermal improvement as full replacement, but it does make a noticeable difference and Exeter City Council’s planning team generally looks on it favourably.

The most reliable way to get an accurate price is to have someone come out and measure properly. Online calculators can give you a rough idea, but the actual cost depends on too many site-specific factors to be accurate from a postcode and bedroom count alone.
