Chapter 01
How much does a garage door cost fitted?
Most single garage doors cost £850 to £3,500 supplied and fitted including VAT as of 2026. Steel up-and-overs are cheapest at £850 to £1,900, insulated electric rollers run £1,800 to £3,200, and insulated sectionals £2,000 to £3,500. Double doors add roughly 40 to 80 per cent.

What size garage door do you need?
The most common UK single garage door is 7'0" × 6'6" (2134 × 1981mm) and the classic double is 14'0" × 7'0" (4267 × 2134mm) — but every door type is measured differently: up-and-overs between the frame, sectionals to the structural opening, rollers with the curtain overlapping it.

Which door type suits your garage?
Choose a sectional for the best insulation and a tight drive, a roller where headroom or space is limited, an up-and-over for the cheapest like-for-like replacement, and side-hinged doors when you walk in more than you drive in. The survey settles it against your actual opening.

Which material should you choose?
Steel is the default: strong, affordable and low-maintenance. Aluminium suits rollers, GRP gives a timber look without timber upkeep, and real cedar looks superb but needs regular finishing and costs from £3,700 fitted. Match the material to your exposure, budget and appetite for maintenance.

Is an insulated garage door worth it?
Yes when the garage is attached to the house or used as a gym, workshop or office: a well-insulated sectional achieves 1.0 to 1.4 W/m²K and cuts heat loss through the door by roughly 80% versus single-skin steel. For a detached storage garage, insulation rarely repays its £700+ premium.

Which colour works on your house?
Anthracite grey remains the most requested colour we fit, black the strongest contrast on light render, and standard white the budget pick. Non-standard RAL colours add £100 to £200 on a single door, woodgrain laminates £200 to £500. Sample swatches come to every survey.
Anthracite vs black, settledChapter 07
Should you automate?
If you drive in daily, yes: operators start at £605 supplied and fitted, and adding automation to a new door costs £400 to £700 — cheaper than retrofitting later. Rollers are electric by default, sectionals automate naturally, and side-hinged doors cannot be automated.

Repair or replace?
If the door is sound, secure and reasonably straight, repair: most faults cost £80 to £350 to fix. Replace when the door is rusted through, failing repeatedly, or repair quotes approach 30 to 50 per cent of a new fitted door. We tell you which side of the line you are on at survey.
