Just thought id drag up this thread as i made my choice and installed it over the Easter holiday period.
I eventually chose"Nearly Grass 40mm" which is a blend of 2 colours, light green is twisted/curly and the Darker green is a straight pile, this costs anywhere between £24 - £40 per sq mt but i found the manufacturers are just a mile away from me so spoke to the factory direct and agreed a price of £17.50 per sq mt inclusive of VAT and Delivery
Completed the job in 3 days, first day was to remove the old turf (not required) add a 2inch layer of sharp (4 ton at £40 per ton) sand and wacker plate it down, cover with a weedproof membrane, not strictly required as the grass has its own inbuilt weed control but for 50p a sq mt it was a no brainer, pegs were £10 for 50 from eBay.
I got the factory to cut the grass into 2 seperate 4 x 6.10 mt rolls
Laid the grass (bloody heavy, took me, wife and 2 late teen sons to lift it into place)
Jointed 2 seperate pieces with joint tape and joint compound ("1 per mt for tape and 2 tubes of glue @ £8 each)
Trimmed edges to form borders and dug in block paving on its edge to creage border edges.
New double palisade fence panels fitted. 6ft x 5ft high to apex at £27 each, 8x garden lights in borders £10 in B and Q sale and bushes at top and down right side have 200 solar LED's in them as well
6x Galvanised large planters (not shown) placed in borders between lights, bargain for £10 off eBay
Should have taken some before pics but never thought
Anyway, these were taken the last time the sun came out, about 2 weeks ago, all in all, very happy, best money ive spent
Just to add that the Dog also loves it, hes sat out there all day and hasn't crapped on it once, he now does he business on the gravelled area which is fine by me
