Talking Utilities

A publication for the UK energy and utilities sector.

Joanne Smalley publishes news and analysis for the UK energy and utilities sector. She writes in Notion and the site rebuilds itself, so a new article goes up without waiting for us.

Publishing
Joanne edits articles, author pages and the standing page text in Notion, and each change triggers a fresh build.
On the site
Five sections, an author page for every byline, and a newsletter signup that does not hand readers to another service.

The front-end website was built to my spec really quickly and needed minimal tweaks — which were delivered in hours.

How it works

There is no price list because there is no standard job. Tell us what you need and your rough budget. We’ll come back with the scope, cost and timing before you commit. If the budget and the work are too far apart, we’ll say so.

  1. Step 1: Tell us what it needs to do

    Who it is for, what it has to do, and when you need it.

  2. Step 2: See the plan

    You get the proposed scope, cost and timing before you commit.

  3. Step 3: See the build

    You get a live link to follow it as it is built.

  4. Step 4: It goes live

    On your domain, with access handed over and a walkthrough of how it all works.

A useful development

A website that helps visitors get things done.

WebMCP lets a site offer clearly defined actions to compatible browser assistants. For a contact form, that could mean preparing an enquiry while the visitor stays in charge of checking and sending it.

It is still experimental. We are testing a careful first use and keeping the ordinary site experience intact.

What is WebMCP, and why does it matter?

The workings, shown

A score needs an explanation.

When we report on a site, we want you to know what a number measures, where it came from and what it leaves out.

This works best when you want to deal with the person doing the work.

You can see the site while it is being built, ask questions as they come up, and know the cost before work starts.

Tell us what you need

What you need, when you need it, and a rough budget.

Or write to hello@sleightof.dev

Everything below is required unless marked optional.

A date, a season, or a good guess.

A ballpark is enough. If it does not fit the work, we’ll say so straight away.

What it has to do, and who it is for.
