WINDOW ADVICE
Helpful information to plan your job, understand costs and choose the right Window Specialist.
RULES & STANDARDS
FENSA and CERTASS are the two government-authorised Competent Person Schemes for window and door replacement in England and Wales. An installer registered with either can self-certify that new windows meet Building Regulations Part L (energy efficiency) without a separate council inspection, and you'll get a certificate proving it — needed if you sell the property.
GOOD TO KNOW
uPVC is the most common choice for cost and low maintenance. Timber suits period and listed properties but needs repainting or resealing every few years. Aluminium is slimmer-profiled and suits larger glazed areas or a more modern look, typically costing more than uPVC for the same size.
COST & QUOTES
An initial quote is usually based on rough measurements and photos; a firm price follows an in-person survey, since window openings in older properties are rarely perfectly square or a standard size. Made-to-measure lead times are typically 2-6 weeks after survey, before installation is booked in.
GOOD TO KNOW
Listed building consent is usually required to replace windows in a listed property, and uPVC replacements are often refused — timber matching the original profile is typically required instead. Conservation areas have similar restrictions even where the property isn't individually listed. Check with your local planning authority before ordering anything.
USEFUL TO KNOW
Trickle vents are the small vents built into a window frame that provide background ventilation without opening the window — increasingly required by Building Regulations on replacement windows to manage condensation and indoor air quality, particularly in well-sealed modern homes.
GETTING A QUOTE
Windows are rated A++ to E based on their whole-window performance (frame and glass together), similar in concept to appliance energy labels. A higher rating generally means better heat retention, but the U-value figure is the more precise technical spec worth asking for if comparing quotes closely.
GOOD TO KNOW
The spacer bar between glazing panes affects both thermal performance and condensation risk at the edge of the glass — modern "warm edge" spacers perform better than older aluminium spacer bars. Worth asking which type is specified, particularly for a north-facing or otherwise cold room.
USEFUL TO KNOW
Double glazing is standard for most UK homes and meets current Part L requirements on its own. Triple glazing further reduces heat loss and noise but costs more and adds weight to the frame — usually only worth the extra cost in an exposed or noisy location, or a new build aiming for very high efficiency.
ABOUT THIS AREA
Bromley is a large town in Greater London, located in the London Borough of Bromley and covered by the BR1 postcode district, about 9.5 miles (15 km) southeast of Charing Cross. An estimated population for Bromley was 329,991 as of 2023. Historically part of Kent, Bromley developed from a market town and grew significantly after the arrival of a railway station in 1858; it is now one of Greater London’s major retail and commercial centres and is identified in the London Plan as one of 13 metropolitan centres. Local planning, building control and permits are administered by the Borough of Bromley, which also oversees parks and local services. For tradespeople and residents, Bromley’s size and commercial role mean a wide range of contractors operate in BR1, covering large‑scale refurbishments, retail fit-outs and common suburban needs such as roofing, rewire and loft conversions. When hiring, allow for potential busy‑centre restrictions on vehicle access and check whether borough consents are required for prominent external alterations.
Bromley’s housing stock and active commercial centre create demand for a wide range of window and door work: from timber sash repair and sympathetic replacements in older houses to uPVC or aluminium units for newer flats and retail shopfronts. In conservation or prominent streets close to the town centre, homeowners may face restrictions on frame materials and appearance, so installers experienced in working to local planning and conservation requirements are valuable. FENSA or CERTASS registration enables installers to self‑certify Building Regulations compliance for replacement windows, giving homeowners assurance that thermal performance and safety standards are being met without separate inspections.
Older sash‑window properties often need timber‑specialist repairs or bespoke units that match original profiles, while double or triple glazing upgrades can significantly improve comfort and reduce noise in a busy metropolitan town. When choosing an installer, ask for FENSA or CERTASS certificates for past jobs, examples of work in properties of a similar age and confirmation of how they will handle any conservation‑area consents. Expect a measured survey, a clear explanation of frame materials and U‑values, and a timetable that takes account of deliveries and any council notice periods for visible external changes.
