Windows Buying Guide
A practical guide to choosing replacement windows with confidence: right style, right material, right glazing and the checks that protect performance, security and long-term value.
How to Choose Style and Material
Start with how each room is used and how your home sits within its street scene. Casement windows are usually the most versatile day-to-day option. Flush, timber-look and vertical sliding designs can suit period-sensitive homes while still delivering modern comfort. Material choice then balances maintenance, appearance and structure: uPVC for practical upkeep, aluminium for slim sightlines, and timber or aluminium-clad timber for heritage-focused detail.
Vertical Sliding and Heritage Looks
Vertical sliding windows suit period-style elevations and can be paired with modern energy and security upgrades.

uPVC, Aluminium or Timber
uPVC is low maintenance, aluminium enables slimmer frames, and timber offers classic character. Hybrid alu-clad options combine benefits.

Glazing should be selected around outcomes, not buzzwords. Double glazing is often the right baseline, while triple glazing can be worthwhile in exposed locations or noise-sensitive rooms. If security, condensation control or outside noise are concerns, ask for a glazing specification that addresses those risks directly.
Double Glazing
A strong all-round choice for most homes, balancing warmth, comfort and value when paired with quality seals and installation.

Triple Glazing
Useful where extra thermal performance or stronger noise control is needed, especially near busy roads or exposed elevations.

Specialist Glazing Considerations
Ask about low-emissivity coatings, laminated security glass and acoustic glazing if heat loss, safety or noise are key priorities.

- Confirm target energy ratings and whole-window U-values, not glass-only figures.
- Ask how frame type, spacer bars and sealing system affect real-world performance.
- Check locking hardware standards (for example PAS 24 options where appropriate).
- Ask for evidence of installation quality controls, not just product claims.
- For exposed or busy locations, request a noise-focused glazing recommendation.
Installer Checks That Reduce Risk
- Survey depth: measured survey, opening condition checks and reveal condition notes.
- Compliance: FENSA and current Building Regulations alignment for replacement works.
- Specification clarity: frame system, glazing build-up, hardware and finish in writing.
- Programme detail: lead times, fitting sequence, and snagging/aftercare process.
- Warranty clarity: what is covered for frames, glazing units, hardware and labour.
Typical Window Replacement Timeline
Timings vary by product and project scope, but a clear sequence helps set expectations and avoid rushed decisions.
Week 1: Home Survey and Scope
Define priorities room by room: style, opening method, materials, comfort targets and budget range.
Week 1-2: Specification and Quote Review
Compare like-for-like specifications before price. Confirm glazing type, hardware and finish details.
Week 2-6+: Manufacturing Lead Time
Made-to-measure windows are manufactured to order. Timings vary with style complexity and finish selection.
Installation Days
Fitting is sequenced by elevation and room use. Installer should protect internal areas and confirm checks on completion.
Handover and Aftercare

Frequently Asked Questions
Is double or triple glazing better for my home?
It depends on your goals and location. Double glazing suits many homes. Triple glazing can add benefit where higher thermal or acoustic performance is needed.
How do I compare quotes properly?
Compare full specification detail first: frame system, glazing build-up, locking hardware, installation scope and warranty terms. This avoids false like-for-like comparisons.
Do I always need planning permission to replace windows?
Not always. Many replacements are permitted development, but conservation areas, listed buildings and Article 4 directions may change requirements.
What security level should I ask for?
Ask for clear hardware and locking specifications and discuss PAS 24-aligned options where appropriate for your property and risk profile.
How long does a full-house window replacement usually take?
Survey and specification can be quick, while manufacturing lead time varies by product. Installation itself is commonly phased over several days depending on scope.
