I'm trying to use the Places library in the Google Maps JavaScript API to get a list of suggestions for pleting a partial UK address. Here's a demo of my progress to date. The code that calls the Google Places API is:

var service = new google.maps.places.AutopleteService();
var query = document.getElementById("address").value;
var restrictions = {country: 'uk'};
service.getPlacePredictions({ 
    input: query, 
    types: ['address'], 
    ponentRestrictions: restrictions},  displaySuggestions);

If I submit a partial address such as "Lowther Road", I get back suggestions such as:

• Lowther Road, Bournemouth, UK
• Lowther Road, Dunstable, UK
• Lowther Road, Stanmore, UK

My problem is that I want a list of matching addresses, not places. Even if I include the house number, e.g. by submitting the partial address "79 Lowther Road", the suggestions returned are still not plete addresses, because the postcodes are missing

• 79 Lowther Road, Bournemouth, UK
• 79 Lowther Road, Dunstable, UK
• 79 Lowther Road, Stanmore, UK

Is it possible to submit a partial address to Google, and get a list of matching (plete) addresses?

You can get plete addresses if you execute a place details request for each prediction that you got via AutopleteService. You should create an instance of the google.maps.places.PlacesService and execute getDetails() for each place ID that you have in the predictions.

Note that get details works asynchronously, so you should use Promises to get all details and display them in the <ul> list.

Have a look at this sample that I created based on your code

// This example retrieves autoplete predictions programmatically from the
// autoplete service, and displays them as an HTML list.

// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script src="https://maps.googleapis./maps/api/js?key=YOUR_API_KEY&libraries=places">

function search() {
  var displaySuggestions = function(predictions, status) {
    if (status != google.maps.places.PlacesServiceStatus.OK) {
      alert(status);
      return;
    }

		document.getElementById("results").innerHTML = '';
    
    var arrPr = []; 
    predictions.forEach(function (prediction) {
      arrPr.push(getPredictionDetails(prediction.place_id));
    });
    
    Promise.all(arrPr).then(function(results) {
  			results.forEach(function(result) {
      		//console.info('Result: ' + JSON.stringify(result, 4));
      		var li = document.createElement('li');
      		li.appendChild(document.createTextNode(result.formatted_address));
          document.getElementById('results').appendChild(li);
        });	
		}).catch(err => {
    		console.log(err);
    });
  };
  
  function getPredictionDetails(placeId) {
  	let promise = new Promise( (resolve, reject) => {
		placeService.getDetails({
        	 placeId: placeId
        }, function(result, status) {
        		if (status === google.maps.places.PlacesServiceStatus.OK) {
            		resolve(result);
            } else {
            		reject(status);
            }
        });        
    });
    
    return promise;
  }

  var query = document.getElementById("address").value;
  var restrictions = {country: 'uk'};
  var service = new google.maps.places.AutopleteService();
  var placeService = new google.maps.places.PlacesService(document.getElementById("results"));
  service.getPlacePredictions({ input: query, types: ['address'], ponentRestrictions: restrictions },  displaySuggestions);
}
