With foreign holidays back on the agenda this year under a traffic light system, British travellers are keen to get a fix of summer sunshine before the winter.

However, travel isn’t as simple as it used to be: many countries now demand tourists present a negative Covid test on arrival, which needs to be taken within a certain timeframe beforehand. This is sometimes referred to as a “Fit to Fly” test. Many countries require the gold-standard PCR test but others are accepting cheaper antigen tests. Check the Covid entry requirements for your destination on the Foreign Office website before booking any tests.

UK travellers are not permitted to use the free NHS testing service and must instead go through a private firm to obtain their result although, increasingly, travel firms are luring holidaymakers with discounted or subsidised travel tests.

All returning travellers, meanwhile, will be required to take at least two tests: one before departing for the UK, which can be an antigen or PCR test; and at least one PCR test within two days of arrival to the UK, depending on their vaccination status and whether they’ve been to a green, amber or red country.

PCR tests for travel can often run into hundreds of pounds, particularly for families.

Here’s where to find a test that’s cheaper than the average.

Providers offering PCR testings at UK airports include Collinson (Heathrow, Gatwick, Luton, City, Manchester, East Midland and Stansted), ExpressTest (Birmingham, Gatwick, Heathrow, Edinburgh) and Randox (Heathrow, Belfast, Manchester, Stansted, East Midlands).

Collinson’s rapid PCR tests, which offer results in three hours, are available at Heathrow for £95. The company’s standard PCR tests cost £69. It also offers pre-departure LAMP tests (rapid tests with results taking between 90 and 120 minutes) for £85.

ExpressTest’s fit to fly PCR tests at its airport branches range from £59 to £80 each, depending on the location. It also offers LAMP and lateral flow tests at some of its branches.

Randox offers express PCR tests for £90 at its airport locations. Day two and eight tests, as well those that enable passengers to test and release on day five, are available for £55 at its airport locations. These tests are done by trained staff at drive-through centres.

Boots UK has launched a PCR self-test package for £65.

It’s selling an at-home PCR self-test – offered by MyHealthChecked – that can be purchased on boots.com and delivered to customers’ homes the next day. The test, which is also available at over 500 Boots stores, can also be purchased by Boots Advantage Card holders using their points.

Boots also offers an in-store Covid-19 PCR Testing Service for £79, which is now available at over 200 stores in the UK and offers results within 48 hours. Its in-store Rapid Antigen Testing Service, meanwhile, costs £49.99 and provides same-day results in more than 50 stores.

All three private Boots tests can be used as a private pre-flight testing service, depending on the specific requirements of the destination country and airline, for customers who require a negative Covid-19 certificate before travelling abroad.

Boots is also now an accredited test provider for the government’s Test to Release scheme, offering next-day results for those wishing to reduce their home quarantine by taking a voluntary test on the fifth day after arriving in England from a country not on the ‘red list’. These in-store tests cost £85 each.

The company’s tests for day two and day eight testing for international arrivals, at-home PCR self-test kits with results available typically within 48 hours from receipt of the sample at the laboratory, cost £68 each or £136 for a days two and eight package.

One of the largest providers of private Covid-19 testing in the UK, Randox offers PCR home testing kits in addition to those available at its testing centres. These cost £45, though discounts are available via a number of airlines (see below).

Britain’s biggest holiday firm has partnered with provider Chronomics which sells a range of tiered Covid test packages to customers travelling to green and amber destinations.

Tui’s testing packages start at £20 for green list travellers who require just a pre-departure lateral flow test and inbound PCR test or day two back in the UK.

Amber packages start at £50 and include UK return pre-departure antigen (lateral flow) test and day two and day eight PCR tests to take on return home.

It’s an extra £40 for PCR tests and an extra £10 for an antigen (lateral flow) test.

If a destination changes from amber to green, Tui says it will refund the difference. If a customer has booked an amber package and no longer need day eight, they can cancel the test and receive a refund by logging into their Chronomics dashboard. Once processed by Chronomics they will receive a refund within 14 days.

Travellers will be able to order tests on a new Chronomics and Tui booking hub.

British Airways is offering discounted rates with government-approved Covid-19 testing providers with prices starting from £22.40.

Options available include:

Test providers include Qured, Randox, Halo, Medicspot and LetsGetChecked.

Tests can be done at home, at testing centres and selected major UK airports.

Passengers travelling on selected routes can also upload their Covid-19 test results to an app called VeriFLY to certify their test certificates.

The budget airline has partnered with testing kit brand Randox to offer passengers money off its PCR tests, which cost £43 rather than the usual £48.

The discounted prices are only available for travellers based in the UK.

The UK’s biggest budget airline has also partnered with Randox Health to offer discounted home testing kits for £43.

EasyJet customers wishing to take pre-departure PCR tests at the airport before departure can take advantage of the airline’s partnership with Collinson. Using the special discount code when booking tests on the Collinson website will get you 20 per cent off the usual price.

This also applies to Collinson’s green list day two test, which you can complete at the airport on arrival in the UK (the day two tests must be completed on or before day two).

The Sofitel at London Heathrow is selling “test and rest” stays for travellers, comprised of a night at the hotel and a PCR test.

On arrival at the Terminal 5 hotel, guests take a self-administered test that requires them to spit in a tube. This is then couriered to a lab at Imperial College in London for processing overnight.

The testing programme is being delivered by biotech firm Halo, and guests must also download the Halo app when they check in.

The app is linked directly to their test, so their result and certificate appears in the app as soon as it’s ready. It means that, provided they don’t test positive for the virus, travellers can wake up ready to fly.

However, this test is a saliva-based test, whereas many destinations specify that the test has to be a nasal swab.

The package costs £229 per person, including a double room. Two people sharing costs £299. Breakfast is available for an additional £19.95 per person.
