A bit like asking to recommend a good car 🙂

It depends on your requirements for... better routing features, your house layout, size, construction materials, your tech abilities, and of course, budget, ~£60-80 will get a decent introductory wireless router but 'may' not alone solve the wifi in your house, but spending up to ~£500 will get the “Rolls Royce” solution of a high-end Wifi6 Router & WAP's or a top end Tri-band Mesh system. You'll probably want something suitable - somewhere within that range - I reckon ~£100-150 is around the “sweet spot” for most standard users, and where you would probably need to start for a standard 2/3-story house if it has brick walls. Less for a one-bedroom modern build flat, more for a stone built 8 bedroom mansion
Good options for Access points/Wifi routers/Mesh systems come from Ubiquiti, Asus, TP-Link Deco's M4/M5, Linksys Velop's, Tenda Nova's, Netgear Orbi's (and others) – I would stick with these companies whose business this is - rather than “newcomer” and data-driven” companies like Google, Amazon, etc. Also be sure the router or Mesh specifically says that they have 1GB ethernet ports - some of the cheaper ones only have 100Mbps ports.
Recently, just as an example... two of my friends who both live in brick built 3/4 bed semis, both just got TP-Link Deco M5 3-packs (~£150) and both told me it is - “absolutely brilliant with full wifi speeds in all rooms, the attic and the garden, and the App is a doddle to use”. The first Mesh unit becomes the new router - you need to check whether the one you look at has all the "features” you need. Ethernet ports are usually limited to 1 or 2/unit , so you “may” need to add in an unmanaged GB port switch (<£20) in there as well. My mates also get "full speeds" from the ethernet ports on the Deco's in the remote locations. Finally if you get a 2/3-pack of any Mesh system, which doesn’t cover dead spots everywhere, you can just add in extra unit(s).
Take a look at what fits your needs, tech ability, house layout and budget. Use sites like Techradar & Techadvisor for reviews of "Best Routers" or "Best Mesh". Post again if you want personal recommendations from others on your short list
