Are you going for a HOMEBASE kitchen? I considered using Homebase and discovered some valuable bits of information. I was provided with a detailed quote, took it home and went through it with a fine toothed comb. I compared the prices in the quote with the prices I could get elsewhere for every item. The kitchen itself was hard to compare (they seem to keep the real cost and name of manufacturer secret). But everything else I subjected to the utmost scrutiny (taps, sinks, worktops, cookers, hoods, plumbing kits, adhesive products, jointing kits etc etc).
At the time Homebase were running a half price sale with a further 15% off. Sounds good? No! It was a complete sham. The prices they quoted WITH those reductions were ON AVERAGE 60% HIGHER than elsewhere. I took my breakdown back to Homebase and the salesman (who had looked at me like I was naïve meat the first time) looked shocked. He said he'd talk to his manager and work up a more competitive quote.
However, he said he COULD NOT SHIFT on the installation cost. Now, my kitchen isn't that big or complex and yet he quoted me £6700 to install! That is absolutely mad. The correct figure should be around £2600 to fit the kitchen plus around £700 to do the electrical and gas bits.
I'm just getting my kitchen fitted now. It's not a Homebase one. I started researching and doing the legwork in March, now it's July and I've learned a shedload on the way.
I recommend the following: Find a fitter, a trustworthy one with over 10 years experience. Ask your neighbours, ask your friends, personal recommendations are like gold dust. That fitter will almost certainly be able to recommend an electrician and a gas man. Look around the smaller independent kitchen companies and look at what they sell. Pick a kitchen you really like at a price you're happy with and get the fitter to obtain & fit it. Set a budget and stick to it!
Keep a separate contingency fund to cover the unforeseen.
You're going to want a kitchen you'll love so learn all about the process. Investigate the best cookers, the best floors and the best worktops. Don't pay silly money for substandard fittings! If you leave it to people like Homebase they'll palm you off with shoddy goods at a premium.
Example: A solid oak 40mm thick/ 40mm stave worktop for my kitchen from Homebase would have come to a whacking £1730! I bought the worktop myself from Worktop Express for £435!!!
Know your stuff! Once you get your teeth into it it's great fun and with your knowledge you'll be able to see the frauds and charlatans a mile off.
