WINDOW GUIDE
Guidance to help with planning, costs and finding the right Window Specialist for the job.
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.
FREQUENTLY ASKED
"Misted double glazing means the whole window needs replacing" — usually just the glazing unit, not the frame. "Triple glazing always pays for itself quickly" — the payback period varies a lot by property and current window condition. "uPVC never needs any maintenance" — hinges and seals still benefit from occasional attention.
PRICING & QUOTES
A conservatory is predominantly glazed (roof included); an orangery has more solid roof/brick structure with a glazed lantern; a garden room is typically a fully insulated, solid-roofed structure suited to year-round use. Building Regulations requirements differ between these, so it's worth clarifying which you're actually getting quoted for.
WORTH KNOWING
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.
WORTH KNOWING
Bifold doors fold back concertina-style for a fully open aperture, good for maximising opening width. Sliding doors have a smaller usable opening (roughly half the total width) but a slimmer profile and often lower cost. The right choice usually depends on how the opening will actually be used, not just the look.
SAFETY & COMPLIANCE
Conveyancing solicitors routinely ask for the FENSA or CERTASS certificate for any window or door replacement done during your ownership. Without it, you may need a retrospective building control inspection, which can hold up a sale — keep the certificate with your house paperwork when the work's done.
USEFUL TO KNOW
Modern replacement windows and doors use multi-point locking as standard, and some are tested to PAS 24 security standards — worth asking about specifically if security is a priority, since not every installer fits PAS 24-rated hardware by default even on similar-looking frames.
USEFUL 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.
ABOUT THIS AREA
Southwark sits on the south bank of the River Thames as the north‑western quarter of the London Borough of Southwark and is one of South London’s oldest districts. Its development grew up around the southern end of the historic London Bridge; Roman engineers recognised the crossing point here around 43 AD, which set the area’s long urban history. By the medieval period Southwark had been incorporated as an ancient borough and places such as the Liberty of the Clink became noted entertainment districts; pieces of City administration persist in institutions like the Guildable Manor. Modern Southwark contains landmarks from Southwark Cathedral and Borough Market to Shakespeare’s Globe, The Shard and the Tate, reflecting a mix of heritage, retail and cultural economy along a prominent river frontage. Administratively it falls under Greater London and the borough council, with the SE1 postcode district defining a compact central area. For trades and property work this central riverside setting implies a mix of historic buildings and contemporary developments: conservation rules can affect exterior works, gated access and restricted parking may complicate on‑site logistics, and demand is high for specialist restoration, high‑spec glazing and commercial fit-outs as well as standard domestic maintenance.
Window projects in Southwark frequently require a careful approach because many properties sit in conservation areas or are adjacent to listed buildings; installers must be prepared to propose materials and styles sympathetic to the original appearance. Timber sash restoration and timber‑specific specialists are often needed for older terraces close to the river, while modern developments commonly require aluminium or uPVC replacements and high‑spec double or triple glazing for noise reduction and thermal performance.
FENSA or CERTASS registration helps installers self‑certify compliance with Building Regulations, but in conservation settings planning consent or listed‑building approval may still be necessary for visible changes. Tight access and gated entrances on central London streets also influence installation methods and logistics. Homeowners should request references for conservation work, check FENSA/CERTASS evidence, and ask about proposed profiles that match the existing streetscape; expect installers to outline any planning permissions that may be needed.
