UK Drivers Licence

No.

So long as you have a UK address which you can use, try to renew it there and then, with a valid UK licence, you should have no problem.
And, whilst I wouldn't disagree with Becasse, I would check with the commune to be absolutely certain.

If you can still use the UK address that is on the licence, relatives living there for example, then you should be able to renew your UK licence using that address. If that isn't possible, it is unlikely that you will persuade the DVLC to renew your licence with a different address because they are likely to demand proof that you live there - a utility bill in your name, for instance - because it won't be a straight renewal, given the time that has elapsed since expiry.
As Kasseistamper says, you could try for an exchange at your commune but they are almost certain to spot that the licence is expired and unexchangeable because some of the dates from that licence are entered on your new Belgian driving licence record.

When I got my BE license, I had lost my UK license completely.

They told me to get a form from DVLA and that was all I needed to get a Belgian one.

Your current license has your driver number on. This should be sufficient for the commune to issue a new Belgian one.

P.S. Don't drive there...

I had the same issue.

I had an expired U.K. license. I could not renew it because I didn’t have a U.K. address.

Thankfully, I found my original paper license which doesn’t have an expiry date.

I returned with that to the commune and the person behind the counter was very kind and used that to generate my BE one.

Had she not done allowed that I would have had to take a Belgian driving test!
