Hidden Window Installation Costs: What to Watch For in Bishop's Stortford

Hidden Window Installation Costs: What Bishop’s Stortford Homeowners Must Watch For

Received a “too good to be true” window quote? It probably is. Hidden costs can turn a bargain into a budget-buster.

I’m Oliver Greene, and in my 38 years in the industry, I’ve reviewed thousands of window quotes. Today, I’ll expose the hidden costs I see most often in Bishop’s Stortford and give you the tools to keep your project on budget.

1. Scaffolding and Access Equipment

Why It Matters

Properties with upper floors or difficult access need scaffolding or cherry pickers.
Typical cost: £400-£1,200 depending on height and duration.

How to Avoid Surprises

Ensure the surveyor assesses access needs.
Request scaffolding charges be included in the quote.

2. Waste Disposal Fees

The Issue

Old windows and packaging must be disposed of legally.
Some installers charge £100-£250 for skip hire.

Oliver’s Tip

Ask if waste disposal is included and whether recycling is used.

3. Finishing Trims and Making Good

Hidden Extras

Internal window boards, plaster repairs, and external trims.
Can add £50-£150 per window if not included.

How to Protect Yourself

Insist on itemized quotes with finishing included.

4. Building Regulation Certificates

Potential Cost

Using building control instead of FENSA adds £300-£500 in fees.

Best Practice

Choose FENSA-certified installers to avoid extra costs and delays.

5. Structural Repairs

Surprise Factor

Hidden rot, lintel issues, or brickwork damage discovered during installation.
Budget 10% contingency or arrange pre-install structural survey.

6. Decorative Extras

Upsell Alert

Decorative glazing bars, special colours, and hardware.
Adds £50-£200 per window.

Decision Framework

Prioritize performance over aesthetics if on tight budget.

7. Interest-Free Credit Fees

Hidden APR

“0% finance” often includes arrangement fees or higher cash prices.

Oliver’s Advice

Compare cash price vs finance price.
