£70 per point supplied and fitted

£69 per point supplied and fitted

68 per point supplied and fitted

£69 is the average then!

Well it might go up if there's a lot of work about or down if there isn't lol

Depends how easy it is to wire a 3 core and earth
might want to go with RF bases bit more money but client will save on labour cost no lifting of carpets moving furniture etc
you can house code too

aico are quite expensive if the customer is willing to pay bang them in.

problem is you still require a feed to each one and in a 3 storey could possibly from 3 different lighting circuits which would require 3 minor works certs so what you give with one hand you take with another

You could design a MWC on your own PC that allows several circuits to certified on it getting round the above problem.

I am sure the ones available on the Elecsa website are set up like this.

We'd go with Aico RF bases for all of them. And probably around the £70 a point price - we'd also probably look to fit an RF test switch too somewhere nice and communal....

As someone said - you're in the position of needing to cert MW on multiple circuits potentially, and to provide a part 6 cert - easy enough on software, but just a thing to bear in mind on the cost really.

Of slightly more concern though.... 3 floors - be careful it's not falling into the need for a full system because of size.... essentially, if a single family dwelling of less than 200m2 overall, you can get away with Grade D - much what you've been asked for, over that, it's Grade A, LD2. If it's an HMO, the rules change again - it's Grade D within dwellings, and Grade A LD2 in communal areas (at which point it's often easier to put the dwellings on the main system with hush buttons).......

Beat me to it bill, but Building regs is 200m2, part 6 classes 3+ foors grade A.
Now if thes properties are domestic, privately own they customer can fit anything the want battery grade F.
If new build then building control will have there say, If Hmo local Aurtority will have theres.

Grr....there's no proofreading for you - should have read overall per floor...... well caught!

Agreed, existing dwellings can fit Grade F (all) as much as they like - new builds (or materially altered) require Grade D minimum.

I don't see any of these points changing much with the revision due out this year either - certainly won't be any reductions, though I've commented liberally on the draft for comment to remove Grades E and F altogether and make D and above a minimum requirement in all refurbs - I don't see where either complies with the essence of having a compliant detection system of any type is as F is battery only and E mains only - no redundancy in either.

Also think it's time there was a joined up national policy for such things - rather than allowing local areas to interpret themselves. I find a lot of inconsistency across even London boroughs, much less counties too.

IMO bill Grade D should be the minimum, there is no place for battery or mains only. Interlink is the only way to keep the db levels high in a domestic or HMO, otherwise we sould be fitting sounders in bedrooms to meet the 75db rule. All London and south are now sing from the same hym sheet over the last year or so, main HMO is either grade D or Grade A with the latter having heat detection in rooms and solo mains/battery smoke in same room.

Yup, totally, and we won't fit less than Grade D anywhere.

I'd like to have hoped that all of London was on the same page - sadly not from experience this week alone - two more or less conversions, one in Lewisham, one in Lambeth..... identical down to the plumbing (and refurbed by same contractor) -

Lewisham wanted Grade D throughout, Lambeth (rightly) Grade A due to size. The two buildings are within three Sqm of each other - 230 sq m per floor over five floors! The clue should have been in that for Lewisham's man. He caved when shown the standard.

Also agree totally on dB requirements - and sometimes think part 6 doesn't go far enough at lower grades - especially given a lot of HMOs get filled with more vulnerable members of society. We found variance on that too though - and too many relying on 13.1.2 of part 6 - which claims 75dB(A) will most likely NOT be achieved at the bed head - it's my belief this has moved on a long way since 2004. Typical sound levels even with interlinked stuff (Aico) can still be as low as 45dB(A) at the bed head when siting of the smokes complies with say a D, or a C.

Being totally honest, it's my view that a minimum Grade A should be fitted in any HMO for two reasons - one, residence is transient by nature, and two, landlord often not on premises, hence limited or no responsible person.

75dB(A) is only a recommendation btw and not enforced at anything under Grade A - again 13.1.2 attests.
