Explore hosting & supportWhy Kestrel
Chosen for the same reasons clients renew every year
Anyone can promise results. We structure every engagement so you can check them — and hold us to them.
One team, end to end
Strategy, design, build, marketing and hosting under one roof --- nothing lost between suppliers, and one number to call when it matters.
Measurable by default
Every engagement starts with agreed numbers and ends with a review against them --- no vanity metrics, no moving goalposts.
Accessible as standard
WCAG 2.2 AA is our floor, not an add-on invoice --- built in from the first wireframe, verified before every launch.
Honest about trade-offs
We would rather win your trust than the upsell --- if a service is not right for you we will say so. It is why 98% of clients stay.
UK-based, always
Design, engineering and support from our Leeds studio. No outsourcing, no time zones, no waiting for tomorrow.
