WINDOW GUIDANCE
Practical pointers to help you plan the work, budget sensibly and pick a reliable Window Specialist.
GOOD TO KNOW
Timber sash and casement windows on period properties can often be draught-proofed and restored rather than replaced, which is sometimes required for listed properties anyway and can be more cost-effective than full replacement if the frames are structurally sound.
RULES & STANDARDS
Do I need a certificate for a single window replacement? Yes, the same Part L rules apply whether it's one window or the whole house. Can I fit my own windows? Technically yes, but you'd then need a separate council building control inspection, which most installers' FENSA/CERTASS registration avoids automatically.
GOOD TO KNOW
For a broken window (break-in, accident, storm damage), boarding up is usually a same-day emergency service separate from full replacement, which follows the normal survey-to-fitting timeline. Ask specifically about emergency call-out availability if security is an immediate concern, not just repair timing.
SAFETY & COMPLIANCE
A proper quote should state frame material and colour, glazing spec, whether old windows/frames are removed and disposed of, the FENSA/CERTASS certificate, and the guarantee length on both frames and glazing units, which can differ.
COST & QUOTES
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.
WORTH KNOWING
Roof windows need to be fitted to the specific pitch and rafter spacing of the roof, and flashed correctly to avoid leaks — this crosses over with roofing work, so some window specialists partner with a roofer for these rather than doing the roof-integration work themselves.
SAFETY & COMPLIANCE
A quote well below others is worth questioning — check it specifies the same glazing spec (U-value), includes the FENSA/CERTASS certificate, and covers disposal of old windows. High-pressure doorstep sales tactics and "today only" pricing are worth treating with real caution in this trade specifically.
USEFUL TO KNOW
A misted glazing unit can sometimes be replaced on its own within the existing frame, which is cheaper and faster than a full window replacement — worth asking specifically if the frame itself is otherwise in good condition, rather than assuming the whole window needs replacing.
AREA GUIDE
Greenwich falls under Greater London and the London region with the SE10 postcode district, and is designated here as a large town. Although no population figure is supplied, SE10 identifies an inner‑London riverside area administered by the Greater London authority, signalling a mix of historic and modern development and tourist activity. For tradespeople, the SE10 postcode helps users find contractors experienced with riverside properties and central London access restrictions, including potential congestion zones and limited parking. Hiring in Greenwich typically requires trades comfortable working in conservation settings or on older buildings, as well as coordinating deliveries in busy urban streets; access for vans and scaffolding permits can be significant considerations. Buyers and landlords should look for contractors knowledgeable about working around high-footfall public spaces and the particular logistical challenges of inner-London projects.
Window specialists working in Greenwich encounter a high proportion of historic facades and conservation constraints alongside modern waterside developments, so installers need to balance thermal performance with appearance. FENSA or CERTASS registration allows firms to self‑certify compliance with Building Regulations, simplifying legal compliance for replacement windows, but conservation areas or listed status may impose additional restrictions on frame material, colour and profile.
Timber sash windows are common on period streets and often require timber‑specific repair or sympathetic replacement to preserve character while improving energy efficiency; secondary glazing can be a practical alternative where external appearance must remain unchanged. In riverside or modern blocks, aluminium or triple glazing options may be appropriate to meet thermal and acoustic needs. When hiring, ask for FENSA/CERTASS registration, examples of work in conservation areas, and a clear plan for proposed frame materials and colours that respect SE10’s historic streetscape.
