A quarter-century of doing it properly.
Liam Swift started this company in 1998 with one goal: to build a firm that homeowners could genuinely trust. Twenty-five years on, that's still the whole business.
Today we're a team of fourteen, six in the office, two representatives, one surveyor, four installers and one engineer, covering London, Kent, Surrey and the South East. Liam is still actively involved in the business every day.
The credentials that back the handshake.
The quiet stuff that separates a proper installer from the rest, in writing, before you commit.

How much does a new window or door cost?
+
Every home is different, so we don't publish rates. What we promise is a free survey, a fixed written quote, and no pressure. Payment is 30% on order, 60% before install and 10% on completion, card or bank transfer, no cash.
How long does an installation take?
+
Most window and door installs are completed in one to three days. A full conservatory or warm-roof project depends on scope; your surveyor will confirm exact timings in your written quote.
What guarantee do I get?
+
One 10-year Swift guarantee covering workmanship, frames, glass units, doors and hardware, with any manufacturer cover included inside those 10 years, plus an Insurance-Backed Guarantee that protects you in the unlikely event we're no longer trading.
What materials do you work with?
+
uPVC, aluminium, timber, composite doors and fire doors. We're an approved installer with every brand we fit, so you get the right product for your home, not the one we're pushing this month.
Which areas do you cover?
+
London, Kent, Surrey and the wider South East. We're based in Greenhithe and previously had a Tadworth showroom, so Surrey is very much on our doorstep.
Do you take on small jobs?
+
Yes. There's no minimum job size, a single replacement window is as welcome as a full-property fit-out. We handle both domestic and commercial work.
