You could start by putting in a queen excluder. You will shortly (within three days), on inspection, know were the queen is. Alternatively you could check the super frames for the queen and if not found shake the bees into the brood box anyway. Getting her downstairs will give you back the supers, for honey, over about three weeks.
It might be good to ensure she has laying space in the brood and add another super if they are doing so well. If it is a lot and capped brood in the supers, more space for honey will come available sooner.
Checking for signs of imminent swarming will be required from now onwards.
You can then plan ahead for increase or requeening. If they prove to be sufficiently docile - they may have been 'ratty' as they may not have been foraging much and are using up stores (remember the many reports of bees being feisty after the OSR finishes and in the autumn?), or simply most foragers at home due to the weather, or ... other reasons - you could put any eggs (in supers) over a fresh added super and see if they build supercedure cells. Then split, as June will be here by the time a new queen would be ready to mate, so mating will be less risky.
Checking for varroa is quick and easy - checking capped drone brood is a good indicator. Leaving a shallow frame in the brood box for drone brood culling might be a good way to check and reduce mites, with the added advantage that the colony will lose a few thousand bees dc ue to thebrood culling - so, again, reducing the risk of swarming.
Odds on they have superceded, at least, in the intervening time unattended, so queenie could be the daughter of your original queen - and some first or second generations can yield horrid queens with some strains.
But reassess before jumping to buy in new queens. No need to be pushed into panic mode by suggestions of requeening immediately. Especially as it seems they are away from your garden, although if on an allotment, for instance, that may be a wise move.
You have so many options, so don't be in any more of a rush than necessary. They have clearly coped without any attention and do not appear to be at risk of imminent colony death, or of causing trouble.
Plan carefully and get it right is my advice.
