You do beautiful work!
That before and after at the bottom of you home page is beautiful! It could use larger images, too. Do you have your originals? You can put large images into BB2 that you can resize down to the content column, yet can gallery (a click on the BB2 image tool) to a much larger image. Also Pinterest images will be as large as the original.
Since Facebook likes a horizontal image and only takes the first one available, it's nice to have that first and a long vertical image for Pinterest.
From one of Cath's and Erin's challenges:
Pin size: 735 px x 1104 px, mobile limit 2061 px height
FB size: 476px x 249px (NEW: 1200 wide x 628 20171205)
The Pinterest Challenge is here:https://forums.sitesell.com/viewtopic.php?f=129&t=222890&hilit=challenge
Yet I'd wait for the updated Pinterest Action Guide when Cath and Erin condense all the good ideas there into many fewer pages and instructions. It's due any time now.
The simple answer is that you can combine the three sites into one, especially now that SBI offers us a 301 redirect (I think it will work between sites, especially SBI sites). You'd want to redirect each page you take down to the exact or best page on the site that you will keep, making sure that that final page has all the info necessary for the different towns.
You can continue to redirect the mikelyonsnewport site to the site you end up keeping. I would think you want to keep your own name's domain for sure. It could redirect to a page on your LyonsFlooring site: mike-lyons-newport.html.
Some considerations: Which one already ranks best? Which one has the most pages to move or redirect? This one looks like the site I'd keep for all the redirects as it has the most pages:[Domain Private]
I am seeing that Cardiff and Newport are different towns. Do you have shops there? If you have individuating info for the different locations (like places where you've worked, photos of jobs there) that info could be T3s from these T2s:[Domain Private][Domain Private]
These pages [Domain Private]
could be moved to T3s under the above Cardiff T2.
Same with the Newport site:[Domain Private]
Your contact info at the bottom of each page can simply go in a site wide dot in the footer.
Social Media? I cannot take the time to look to see if you have the several social media for each site. Oh! What a time sucker that can be! Me? I would surely combine all to one for each SM.
Your personal note at the top can go in a site wide dot, too. Having so much info the same with only the keyword changed is probably not good SEO.
You can expand the LyonsFlooring-UK in your header and H1 on the home page by writing: Lyons Flooring, Tile, and Stone (or whatever keywords work best - Lyons Flooring, Stone and Tile). As you said, the best page for the info will get the traffic.
KEEP these many domain names. Park them in Name Park It. Support can help you with this.
A suggestion: Add a large unique picture to each page as you review it. Also, add captions so visitors and the search engines know what's being shown. Beautiful pictures will sell your beautiful work!
Oh, how I wish good men in our area would do this for themselves!
I hope this helps. I must quit. No time to review well.
PS: May I beg you to add more photos like the Flash players here:[Domain Private]
