Carpet Cost Calculator
How to Measure Your Room
Accurate measurements are essential for calculating carpet costs and ordering the right amount of material. Follow these steps for precise measurements:
- Clear the room of furniture and obstacles where possible to access all areas
- Use a tape measure to measure the longest wall length in metres
- Measure the widest wall width in metres
- For irregular shaped rooms, divide into rectangles and measure each section separately
- Add 10cm to each measurement to allow for trimming and fitting
- Note any alcoves, bay windows or doorways that may affect the carpet layout
- Measure doorway widths to determine if door adjustments will be needed
Top Tip: Carpet is typically sold in 4m or 5m widths. If your room is wider than these measurements, your fitter will need to create a join. Ask about placement options to minimise visibility.

Pile Types Explained
The carpet pile refers to the surface texture and how the fibres are constructed. Each pile type offers different benefits:
- Loop Pile: Fibres are looped and uncut, creating a textured, durable surface ideal for high-traffic areas and pet-friendly homes
- Cut Pile: Loops are cut to create an upright, plush finish that feels soft underfoot, perfect for bedrooms and formal living spaces
- Twist Pile: Tightly twisted fibres stand upright, offering excellent resilience and hiding footprints and vacuum marks effectively
- Saxony: Cut pile with a smooth, luxurious finish, best suited to low-traffic areas as it shows marks more readily
- Frieze: Long, twisted fibres create a casual, textured appearance that conceals footprints and is highly durable

Underlay Selection Guide
Quality underlay extends carpet life, improves comfort and enhances insulation. Consider these factors when choosing:
| Underlay Type | Thickness | Tog Rating | Lifespan | Recommended Use |
|---|---|---|---|---|
| Foam | 8-9mm | 0.75-1.0 | 5-7 years | Light use, budget projects |
| PU Foam | 9-10mm | 1.2-1.5 | 7-10 years | General residential use |
| Rubber | 9-11mm | 1.5-2.0 | 10-15 years | High-traffic areas, stairs |
| Felt | 10-12mm | 2.0-2.5 | 12-20 years | Luxury installations, heavy carpets |
Underfloor Heating: Keep combined carpet and underlay tog rating below 2.5 to allow heat to pass through efficiently. Choose thinner underlay with lower tog values for rooms with underfloor heating systems.

Frequently Asked Questions
How much carpet waste should I allow?
+
Add 10% to your measurements to account for pattern matching, cutting errors and awkward corners. For rooms with bay windows, alcoves or irregular shapes, increase this to 15%. Carpet is sold by the linear metre in 4m or 5m widths, so your fitter will calculate the most economical way to cover your floor area.
Is underlay really necessary?
+
Whilst technically optional, underlay dramatically extends carpet lifespan by cushioning foot traffic impact. It improves comfort, reduces noise transmission between floors, and provides additional insulation that can lower heating costs. Most manufacturers require underlay for warranty coverage, and fitting without it may void guarantees.
How long does professional carpet fitting take?
+
A single room typically takes 2-4 hours including preparation, fitting and cleanup. Whole house installations average 1-2 days depending on property size and complexity. Stairs require additional time due to precise cutting and fitting requirements. Your installer will provide a time estimate during the quote stage.
What preparation is needed before fitting?
+
Remove all furniture from rooms being carpeted. Take down curtains to prevent dust damage. Remove old carpet unless you’ve arranged professional removal. Check floorboards for loose boards or damage and repair as needed. Vacuum subfloors thoroughly. Notify your fitter of any radiators requiring temporary removal or underfloor heating systems.
Can I fit carpet over existing flooring?
+
Carpet can be laid over vinyl or laminate flooring if the surface is smooth and level. However, this adds height which may cause door clearance issues. Fitting over tiles is not recommended due to grout lines creating an uneven surface. Most professionals recommend removing old flooring for best results and to avoid future problems.
How often should carpet be replaced?
+
Budget carpets typically last 5-7 years, mid-range nylon carpets 8-12 years, and quality wool carpets 15-25 years with proper care. High-traffic areas wear faster than bedrooms. Replace carpet when it shows permanent staining, worn patches, odours that cleaning cannot remove, or if underlay has compressed and lost cushioning properties.
What’s the best carpet for pet owners?
+
Loop pile carpets in nylon or polypropylene work best for homes with pets. Short loops prevent claw snagging whilst making hair removal easier during vacuuming. Polypropylene offers excellent stain resistance for accidents. Avoid long cut pile and wool, which trap hair and absorb odours. Darker colours and patterns help conceal pet hair between cleaning sessions.
Do I need to remove skirting boards?
+
Skirting boards typically remain in place during carpet installation. Fitters tuck carpet edges beneath skirting boards using specialist tools for a neat finish. Removing skirting boards is only necessary if they’re damaged, if you’re replacing them, or in rare cases where the carpet pile is exceptionally thick. Discuss with your fitter during the quote stage.
What causes carpet rippling and how can I prevent it?
+
Rippling occurs when carpet isn’t properly stretched during installation, when humidity changes cause fibre expansion, or when poor quality underlay compresses unevenly. Prevention requires professional power stretching during fitting, climate-controlled storage before installation, and quality underlay appropriate for carpet weight. Most rippling within the first year indicates poor installation.
Should I carpet or use hard flooring on stairs?
+
Carpet offers superior safety on stairs by providing grip and cushioning in case of falls, particularly important for households with children or elderly residents. It reduces noise transmission between floors and feels warmer underfoot. Hard flooring looks sleek but can be slippery and noisy. Many homeowners choose carpet for safety whilst using runners for aesthetic appeal.
Maintenance & Care Tips
Proper maintenance extends carpet life and keeps it looking fresh. Follow these care recommendations:
Regular Maintenance
- Vacuum high-traffic areas twice weekly, other areas once weekly minimum
- Use carpet protector sprays on new installations to create a stain-resistant barrier
- Rotate furniture periodically to prevent permanent indentation marks
- Use entrance mats to reduce dirt and moisture tracked onto carpets
- Attend to spills immediately by blotting (never rubbing) with clean absorbent cloths
Deep Cleaning
- Professional steam cleaning every 12-18 months maintains appearance and hygiene
- Hire carpet cleaning machines for DIY deep cleaning at approximately £25-£35 per day
- Allow 6-12 hours drying time after wet cleaning before replacing furniture
- Avoid over-wetting which can damage backing and promote mould growth
Stain Removal
- Blot liquid spills immediately with white absorbent cloths, working from outside edges inward
- Scrape solid residues gently with a blunt knife before treating
- Use carpet-specific cleaning products matched to stain type and carpet material
- Test cleaning solutions on hidden areas first to check for colour fastness
- Avoid harsh chemicals like bleach which permanently damage carpet fibres
When to Choose Carpet Over Hard Flooring
Both carpet and hard flooring have distinct advantages. Carpet excels in specific situations:
- Bedrooms: Warmth and softness underfoot create a comfortable environment, whilst sound absorption promotes better sleep quality
- Stairs: Cushioning and grip reduce slip hazards, especially important for children and elderly household members
- Upper Floors: Sound dampening prevents noise transmission to rooms below, maintaining household peace
- Cold Climates: Superior insulation properties reduce heat loss through floors, potentially lowering heating costs
- Family Homes: Softer surface reduces injury risk from falls and provides comfortable play areas for children
- Rental Properties: Budget carpet options offer cost-effective flooring that’s easily replaced between tenants
Hard flooring proves more suitable for kitchens, bathrooms, hallways with exterior doors, and homes with severe allergies or pets that shed heavily.
Environmental Considerations
Environmentally conscious homeowners have several sustainable carpet options:
Sustainable Materials
- Wool: Renewable natural fibre that’s biodegradable and has low environmental impact during production
- Recycled Nylon: Made from reclaimed materials including old carpets and fishing nets, reducing landfill waste
- Plant-Based Fibres: Sisal, seagrass and jute offer renewable alternatives, though less soft than traditional carpets
- Recycled PET: Manufactured from plastic bottles, diverting waste whilst creating durable carpet fibres
Eco-Friendly Practices
- Choose carpets with low VOC emissions certified by recognised environmental standards
- Opt for natural rubber or felt underlay instead of synthetic foam alternatives
- Extend carpet life through proper maintenance rather than premature replacement
- Arrange carpet recycling through specialist programmes rather than landfill disposal
- Select local manufacturers and suppliers to reduce transportation carbon footprint
