What To Consider When Buying New Windows

If you’ve recently decided it’s time to upgrade your house with new windows, it’s an exciting prospect – giving your home a fresh look and improved thermal performance. But that excitement is often met with uncertainty when you start researching and find yourself faced with dozens of decisions. Styles, materials, colours, glazing options – and when you’re making a considerable investment, you want to get it right.

Most of these choices become much simpler once you’ve answered a few key questions first. After 50 years of helping homeowners across Lincolnshire, we’ve found that the secret is tackling your requirements in the right order. Get your budget and priorities clear, and your options naturally narrow down until you find the ideal choice.

Here’s the step-by-step process we use with our customers.

Step 1: Understand Why You’re Replacing Your Windows

Before you start browsing styles or colours, take a moment to pin down exactly why you decided to replace your windows in the first place. This might seem obvious, but it will help keep you on track to make the right decisions.

Energy Efficiency Issues

Most modern windows offer excellent U-values and energy-efficient glazing specifications that can contribute to reducing your heating bills. However, performance varies significantly between products, so always ask suppliers for specific thermal performance figures rather than assuming all new windows are equally efficient.

Draughts and Condensation

Here’s some advice that many people don’t realise: draughty windows don’t always need full replacement. Sometimes the issue is poor installation or worn seals rather than the windows themselves. If your windows are relatively modern, it’s worth contacting the original installer or a window maintenance specialist to check whether resealing could solve the problem and save you thousands of pounds.

Noise Problems

Standard double glazing reduces external noise considerably, but if you live near a busy road, airport, or other constant noise source, you’ll want to specifically request acoustic or laminated glass options. These don’t usually come as standard, so mention noise reduction as a priority from the start.

Security Concerns

Modern windows offer far better security than older designs, but specifications do vary. When comparing quotes, ask about locking mechanisms, hinge protection, and glazing options. 

Aesthetics and Property Value

This is something that is often overlooked. The style of your windows should complement your home’s architecture. Installing ultra-modern windows on a Victorian terrace or traditional designs on a contemporary build can harm your property value. Take time to look at similar properties in your area and see what works well.

Maintenance Burden

If you’re tired of scraping and painting timber windows every few years, uPVC or aluminium windows offer a low-maintenance alternative. They won’t rot, and they typically only need occasional cleaning with soapy water to keep them looking pristine.

Why This Step Matters

Your initial reasons for replacing your windows will determine which features matter most and where it’s worth spending extra. A homeowner focused on energy savings has different priorities than someone primarily concerned with kerb appeal, and your budget should reflect that.

Step 2: Set a Realistic Budget for Your New Windows

The cost of new windows is what most customers want to know first. Here’s roughly what to expect:

Entry level (£200-600 per window fitted): uPVC casement with A-rated double glazing. These are perfectly good windows that last 20+ years and meet all Building Regulations. There’s nothing wrong with choosing this tier if it suits your budget.

Mid-range (£600-900 per window): Choice of materials, sophisticated designs, and increased specifications are often what push windows into the mid-range tier. This is where most Lincolnshire homeowners end up, and it typically offers the best balance of performance and value.

Premium (£900+ per window): Aluminium, triple glazing, bespoke styles, heritage authenticity. Worth it if your property demands it or if longevity and aesthetics are your priority.

Don’t forget potential additional costs. Scaffolding (if needed) can add £400-800, though most installations can be done from inside. Budget a 10-15% contingency for repairs to window reveals – you often don’t know what’s behind old windows until you remove them. Disposal of old windows is usually included but confirm this with your installer.

Step 3: Match Your Window Style to Your Property Type

Your property type might restrict your choices just as much as any other factor you need to consider. Understanding this early saves wasted time and disappointment.

Planning and Conservation Restrictions

Period or heritage properties: Check your local council’s planning portal first. Many areas have Article 4 directions restricting what you can install. Finding this out after planning a uPVC installation wastes time and money.

Listed buildings: You’ll need like-for-like replacement and planning permission. This usually means timber windows, which significantly affect both cost and maintenance expectations.

Conservation areas: You may need planning permission, especially for front elevations. Even if you don’t, your choices should respect the area’s character.

Location-Specific Considerations

Coastal or exposed locations: Standard hardware can corrode quickly. Consider marine-grade aluminium and stainless-steel hardware – it costs more initially but saves replacement costs.

Urban or roadside properties: Noise reduction becomes as important as thermal performance. You’ll want to seriously consider acoustic glazing options.

Bay windows: These are more complex installations and typically cost 40-60% more than standard windows of similar size. Factor this into your budget.

Architectural Style Matching

Just because you like a style doesn’t mean it suits your home. We’ve had customers insist on modern grey aluminium windows on Victorian terraces, and whilst we try to provide customers with exactly what they want, we’re also honest about suitability.

Victorian or Edwardian homes: Sash windows are almost always the right choice. Casement windows can also look appropriate depending on the style.

1930s semi-detached properties:  Casement windows are typically suitable. This is good news because they’re usually more affordable than sash alternatives.

Post-war (1950s-70s) properties: Flush casements are more authentic than standard casements and are becoming increasingly popular.

Modern or new build homes: You generally have the most freedom when selecting styles for modern properties. Slimline aluminium is popular for contemporary looks.

Sometimes the authentic choice is the better long-term investment, even if it’s not your initial preference.

Step 4: Choose Window Materials and Glazing Specifications

By now, your previous decisions have narrowed down your options significantly. Here’s how to make the final choice.

Window Material Options

uPVC: Best for standard replacements, energy efficiency on a budget, and low maintenance. It’s the most popular choice for good reasons. Avoid if you need very slim sightlines or if you’re in a conservation area where it might not be permitted.

Aluminium: Best for contemporary designs, coastal locations (it doesn’t corrode like other materials), and achieving maximum glass area with minimal frame. Avoid if budget is tight – it typically costs 50-70% more than equivalent uPVC.

Timber: Best for listed buildings and conservation areas where it’s often your only permitted option. However, if you do have a choice, modern uPVC and aluminium can replicate authentic period styles with superior thermal performance, better security, and far less maintenance.

There really is no “best” material overall. It’s about choosing what works for your specific situation. 

Glazing Specifications

For energy efficiency: Building Regulations require a maximum U-value of 1.4 W/m²K. A-rated double glazing (1.2-1.4 W/m²K) is adequate for most Lincolnshire homes and meets regulations comfortably.

Triple glazing (0.8-1.0 W/m²K) costs 20-25% more. Here’s what we tell our customers: unless you’re in an extremely exposed location or building to specific standards, the payback period is often 25+ years. For standard replacement windows, the energy saving alone rarely justifies the additional cost of triple glazing.

For noise reduction: Standard triple glazing often doesn’t help with noise; you need acoustic laminated glass with different thickness panes. Be realistic about expectations: even the best acoustic glazing reduces noise by 35-40 decibels. That turns heavy traffic into a background hum, not complete silence.

For security: Ground floor windows and accessible windows should have laminated glass, which stays in the frame if smashed. Combine this with multi-point locks for genuine security.

Step 5: Navigate Requirements and Get Quotes

The final step covers the practical and legal requirements you’ll need to meet, plus how to get comparable quotes.

Building Regulations and Compliance

Building Regulations compliance isn’t optional – it affects your ability to sell your property in the future.

FENSA-registered installer (easiest option): We self-certify Building Regulations compliance and you receive a FENSA certificate within weeks at no extra cost. This is what most homeowners use.

Without proper certification: Your solicitor will ask for FENSA certificates if you sell your home. Without them, you’ll need retrospective Building Control approval indemnity insurance. Sales can fall through due to missing certificates. Our guidance: always use a FENSA-registered installer – it’s not worth the risk.

Practical Requirements

Trickle vents: Building Regulations require these in habitable rooms. Don’t refuse them – they prevent condensation and are legally required. They’re also much less noticeable on modern windows.

Fire escape requirements: Bedroom windows must be wide enough to escape through and operable without keys. Your installer should know this, but mention it if you’re replacing bedroom windows.

Child safety: Upper-floor windows where children are present should have restrictors limiting opening to 100mm.

Easy-clean options: Tilt-and-turn windows and some other hinge types let you clean the outside from inside – worth considering for upper floors or difficult access situations.

Getting Comparable Quotes

A good supplier will naturally walk you through all these steps and provide honest advice based on your specific situation. You shouldn’t have to become an expert before picking up the phone.

That said, when you do contact installers, tell them clearly what you need so you receive comparable quotes rather than wildly different proposals you can’t sensibly compare. Include: property type, number of windows, your primary reason for replacement, budget range, material preference, style required, glazing specification, and any constraints like conservation area status or difficult access.

How many quotes you get is entirely up to you. Some people prefer to speak with just one or two installers they trust, whilst others want to compare four or five options. There’s no right answer. What matters most is that you don’t feel pressured into making a decision on the spot, and that you consider more than just the price.

Compare specifications, warranties, whether the installer is FENSA registered, how well they listened to your requirements, and whether their advice felt genuinely helpful or just like a sales pitch. The cheapest quote isn’t always the best value, and the most expensive isn’t always the best quality.

Still Got Questions?
