WINDOW ESSENTIALS
A quick guide to planning your project, understanding costs and choosing a good Window Specialist.
GOOD TO KNOW
In a leasehold flat, window replacement sometimes needs freeholder or management company permission, particularly if it affects the building's external appearance — check your lease before booking work, not after ordering.
WORTH KNOWING
A garden room used year-round needs the same Part L-compliant glazing as house windows, not just any glazed unit — worth checking this is specified if you're having a garden office or similar built, since it affects both comfort and any future certification needed.
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.
RULES & STANDARDS
You should receive a FENSA or CERTASS certificate within a few weeks of completion — chase it if it hasn't arrived, since some installers register the job but delay sending the physical certificate. Keep it with your house paperwork; you'll need it when you sell.
GOOD TO KNOW
Fitting itself is typically one day per 4-6 windows once the made-to-measure units arrive (the survey-to-fitting lead time, 2-6 weeks, is usually the longer wait). A full house re-glaze commonly takes 1-3 days of on-site work.
WORTH KNOWING
French doors suit a more traditional look and a narrower opening than bifold or sliding doors, but both leaves typically need to open for full access, unlike sliding or bifold options. The right choice often comes down to the room layout and how the space is actually used day to day.
THE PROCESS EXPLAINED
A composite front door typically offers better security and insulation than a standard uPVC door at a similar price point. Multi-point locking, a door viewer, and anti-snap cylinder locks are all worth asking about specifically rather than assuming they're included as standard.
GOOD TO KNOW
Toughened (safety) glass is required by Building Regulations in doors and low-level windows. Laminated glass adds security and noise reduction. Obscure (patterned) glass is used where privacy matters, like bathroom windows, without losing light — worth specifying which you need per opening rather than assuming standard clear glass throughout.
AREA GUIDE
Farnham is a market town and civil parish in Surrey, around 36 miles southwest of London within the Borough of Waverley and operating under the GU9 postcode district. The town occupies the north branch of the River Wey and sits at the western edge of the North Downs; the civil parish includes nearby villages such as Badshot Lea, Hale and Wrecclesham and covered some 14.1 square miles at the 2011 census with a population close to 39,500. Farnham has deep historical roots — Saxon-named, with prehistoric finds and a medieval castle linked to the Bishops of Winchester — and has evolved through cloth production, hop growing and Victorian-era expansion following the arrival of the railway. For tradespeople, GU9 locates a market with substantial stock of older buildings, conservation areas and period properties requiring sensitive repairs, conservation-led planning and possibly specialist materials. Local contractors often provide services in historic-structure work, heritage roofing, traditional joinery and retrofit measures appropriate for a mix of listed and non-listed homes; access for vehicles can vary between narrow town-centre streets and more spacious suburban roads.
Window work in Farnham often sits at the intersection of heritage sensitivity and modern performance needs: town-centre properties and some suburbs include conservation areas and listed buildings where frame material, sightlines and traditional proportions matter, while other homes benefit from uPVC or aluminium upgrades for thermal efficiency. Installers operating locally frequently handle sash-window repairs, bespoke timber frames and secondary glazing to preserve appearance while improving insulation — projects where timber-specific skills and careful finishing are important. Registration with FENSA or CERTASS allows installers to self-certify Building Regulations compliance, which simplifies paperwork for replacements and ensures documented compliance with thermal and safety standards.
For conservation or listed properties, expect restrictions on frame style and finish and ask whether the installer has experience with timber sash repairs or approved sympathetic u-values for conservation settings. When choosing an installer, request to see previous work in conservation areas, check FENSA/CERTASS membership and ask for detailed drawings showing sightlines, frame materials and how new units will marry up with existing brick or stone reveals; also confirm timescales for any planning or listed-building consents if relevant.
