Find Local SpecialistsWhat to Expect When Having Windows Replaced in Cavendish Square
A typical window replacement in Cavendish Square is less disruptive than most homeowners expect. An experienced team will usually replace a standard casement window within an hour or two, and a full house of windows can often be completed in a single day. You'll need to clear the area around each window and expect some dust and noise during removal of the old frames.
Your Window Specialists should protect flooring and internal surfaces, seal openings promptly to maintain security, and carry out a thorough check of every window before completing the job. You should receive your FENSA compliance certificate by post within 30 days of the registered installation date.
Insurance and Deposit Protection for Window Work in Cavendish Square
Before paying any deposit to a window specialist in Cavendish Square, confirm that the company holds public liability insurance and that your deposit is protected. Reputable glazing companies operating under the Consumer Code for Home Improvements provide deposit protection as standard, meaning your money is safeguarded if the company ceases trading before completing the work.
Never pay the full cost upfront. A reasonable deposit — typically 10–25% — is normal for ordered goods; the balance should be due on satisfactory completion. Our listed Window Specialists meet these standards as part of our vetting process.

What a Fair Window Quote Looks Like — and Red Flags to Watch For
A fair quote from a window specialist in Cavendish Square will be detailed and itemised, covering products, installation, removal and disposal, FENSA registration and guarantee terms. It will be provided in writing after a site survey, not over the phone. The salesperson will not use high-pressure tactics or claim the price is only valid for that day.
Red flags include: quotes that change significantly after signing, requests for full payment upfront, pressure to make a same-day decision, unusually low prices that don't reflect the scope of work, and companies unwilling to provide a FENSA number or proof of insurance on request. Taking time to compare at least three quotes from vetted Window Specialists in Cavendish Square is the most effective way to identify fair market pricing.
Frequently Asked Questions — FENSA and Certification in Cavendish Square
FENSA is a government-authorised competent person scheme that allows registered window installers to self-certify that their work complies with Building Regulations. This means you receive a compliance certificate without needing to separately notify the local council.
The work must be inspected and certified by your local authority building control department, at additional cost and delay to you. Uncertified window replacement can cause problems when you sell or remortgage.
FENSA registered installers submit installation details to FENSA within 30 days of completion. Your certificate is then posted to you directly from FENSA, not the installer. Keep it with your property documents.
CERTASS is an alternative government-authorised competent person scheme for window and door installers. It performs the same self-certification function as FENSA. Both are equally valid for Building Regulations compliance purposes.
In England and Wales, replacing a window with one of a different specification (e.g. upgrading to double glazing) must comply with Building Regulations and should be certified. Like-for-like replacement in the same opening with equivalent thermal performance still requires notification or self-certification.
