.NET Consulting in London
Advice for London organisations across the .NET estate, where the first question is which .NET you are on. The original Framework is Windows-only and receives fixes rather than features; modern .NET is cross-platform and releases annually with long-term support versions — and applications are frequently split across both without anyone having decided that.
Why this comes up
The problem
Some services run on the old Framework and some on modern .NET, and nobody has a position on where the estate is heading.
What you get
What we deliver
- Every application placed on one side of the divide, with a stated direction
- Migration candidates prioritised by business value rather than by technical ease
- Applications that should stay identified honestly, since not all need moving
- Long-term support versions targeted rather than the newest release
- Hosting reconsidered, as modern .NET removes the Windows requirement
- Upgrade cadence established within the support windows

London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

.NET Consulting in London — common questions
- Does everything need to move off the old Framework?
- No, and pretending otherwise wastes money. It remains supported as a component of Windows and receives fixes, so a stable internal application with no development planned can reasonably stay — what matters is that this is a decision rather than an oversight.
- What does moving actually gain?
- Performance, cross-platform hosting and access to current development. For an application under active development those are substantial; for one that has not changed in five years they are benefits nobody will use, which is why prioritisation matters.
- Which version should we target?
- A long-term support release. Modern .NET ships annually with alternating support lengths, and targeting the long-term versions gives a predictable multi-year window rather than requiring a move every twelve months.
- Does hosting change?
- It can, and it is frequently where the saving is. Modern .NET runs on Linux and in containers, which opens hosting options that were unavailable before — worth including in the business case rather than treating as a technical detail.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
