What gets surveyed in Wales

Slate is the recurring theme. Valleys terraces stepped up hillsides, chapels, farmhouses and barns — Welsh roofs are overwhelmingly slate, and slate fails one piece at a time: a slipped slate here, a delaminating face there, nail-sickness across a whole pitch. High-resolution stills from a drone pick out individual slates, which is exactly the evidence a roofer, insurer or conservation officer asks for before anyone prices a repair.

The land work is just as broad. Hill farms commission field-by-field topos and drainage mapping; forestry covers big tracts of mid and North Wales; and the slate landscape of the north-west — now World Heritage-listed — still holds working quarries and a century of tips that get surveyed for stability and planning. On the energy side there are onshore wind farms down the spine of the country, offshore arrays off the North Wales coast and solar farms across the south, while heavy industry around Port Talbot and the southern ports adds structural and stack inspection work.

Then the coast. The Wales Coast Path runs roughly 870 miles, and a fair share of that is eroding cliff, harbour wall and sea defence that somebody is responsible for monitoring. Repeat drone flights measure what has changed between visits without putting anyone on the cliff edge.

Airspace in plain English

Cardiff Airport's Class D zone sits over the Vale of Glamorgan coast and the airport's approaches — most Cardiff city-centre jobs fall outside it, but pilots check the boundary rather than assume. It is the only civil control zone of any size in the south.

The military presence is bigger than the civil one. The Aberporth danger areas over Cardigan Bay protect the UK's main drone test range at West Wales Airport; Sennybridge and Castlemartin run live firing under their own danger areas; and fast jets train low through the mid-Wales valleys — the Mach Loop near Machynlleth most famously — on most weekdays. None of these is a permanent no-go for a survey: they activate on published schedules, and local pilots check NOTAMs and range activity before confirming your date.

In the north, RAF Valley's zone covers part of Anglesey and stays busy with training jets through the working week. Eryri and Bannau Brycheiniog, for all their other rules, don't restrict the airspace itself — take-off and landing permission from the landowner is the thing that needs arranging.

Weather windows, honestly

Wales takes the Atlantic weather first, and the uplands are among the wettest places in Britain — which the slate roofs already knew. The practical effect is that dates here are windows, not fixtures: pilots watch the front coming through, fly the calm slot behind it, and will move a booking rather than fly marginal conditions.

Valleys funnel wind, mountains make their own weather, and conditions in Eryri can turn inside an hour — upland jobs get a margin built into the deadline. The coast is windier but clears faster. Mornings are reliably the calmest slot almost everywhere.

Flying happens all year. Winter brings fewer usable days and shorter ones, but it is also the season for thermal heat-loss surveys; big mapping jobs are easiest to schedule in the long daylight between April and September.

Where the pilots actually are

The count above is the real one, and the map behind it is lopsided: most Welsh pilots are based around Cardiff, Newport and Swansea or along the north coast, with mid Wales covered by those willing to drive — several are, and the travel appears in the quote rather than smuggled into extras.

For Powys, Ceredigion and the remoter stretches of coast, expect fewer quotes and slightly longer lead times, not silence. Your request goes to every listed pilot covering your area, and if genuinely nobody does, we say so. Posting one costs nothing — the form on the homepage takes about two minutes.
